Planning • To find out how much paint you’ll need you must first calculate the area to be painted. Measure the height and width of each wall, then multiply the results together to give you its area. Do the same for each window and door, counting any open hatches as windows and any doorless frames or arches as doors. • Add the areas of all the walls together and subtract the areas of all the doors and windows. The calculation will look something like this: 5.44 m x 2.07 m 0.9 m (h) x 1.145 m (w) • Ascertain the spread rate of the paint. If it’s not printed on the side of the tin, check with the manufacturer. The rate is often given as m²/ℓ. Now divide the m² you need to paint by the spread rate. For instance, if the spread rate is 9 m²/ℓ, then the example above would need 13.76 ÷ 9 = 1.53 litres. If two coats are required, simply multiply 1.53 by 2 (= 3.06). 2.532 m (w) x 2.07 m (h) 2.1 m (h) x 0.813 m (w) Wall 5.44 m x 2.07 m = 11.2608 m² Wall 2.532 m x 2.07 m = 5.24124 m² Door 2.1 m x 0.813 m = 1.7073 m² Window 0.9 m x 1.145 m = 1.0305 m² Calculation 11.26 + 5.24 – 1.71 – 1.03 = 13.76 m² 2 • There are many online calculators which will do the calculations for you. • Having bought the paint, take time to read the directions on the tin for the proper way to prep and prime your walls before painting them with that specific paint. Painting equipment SANDING need to start with a coarse grit, whereas if you are just scuffing the surface to paint over it, you will need an extra fine grit (220). WIRE BRUSHES What you will need: - Sanding block - Wire brushes - Scrapers - Putty knife or filler tool - Mutton cloth - Disposable overalls - Paint shield - Painter’s tape Sanding a previously painted surface before repainting it ensures that the new paint or primer will bond well with the surface and you end up with a lasting, quality coat. Some electric sanders are too abrasive to use on paint so you have to be careful not to gouge the surface with them. Always choose sandpaper with the right grit for the job. For removing old paint you will - Polycell brush cleaner - Paint paddle/stirrer - Drop cloths, plastic sheeting - Paint pot/kettle These are mainly used for removing old paint and rust. They come in all shapes and sizes and also as attachments for electric drills (excellent for cleaning rusted burglar bars). - Safety gear - Paintbrushes - Rollers - Crack filler 3 DISPOSABLE OVERALLS SCRAPERS Scrapers are ideal for removing old paint, rust, putty or glue but as they have sharp edges and corners, mind you don’t scar the surface with one. Before storing a scraper, make sure it’s clean. A quick wipe with turpentine will do the job. it’s easier to press filler into a crack and scrape off the excess afterwards. Once dry, sand the filler smooth, paint with plaster primer and then your topcoat. MUTTON CLOTH PUTTY KNIVES OR FILLER TOOLS Before filling a crack, knock off any loose bits of plaster, brick or paint and brush out any loose material and dust. Open up the crack if necessary. Paint the crack with plaster primer to ensure the filler bonds well with it, then use a putty knife or filler tool to press the filler into the crack. A filler tool is similar to a scraper but has a more flexible blade with which 4 A pure cotton, soft and absorbent fabric that’s ideal for buffing, polishing, dusting and cleaning. Some waxes and polishes cannot be removed by washing so it’s best to keep separate cloths for specific uses. Mutton cloth is good for wiping up spills too. These are really convenient and can be reused, but they won’t hold up to a wash. You can buy just a jacket or a whole suit that protects all your clothing and hair. They are breathable and lightweight with elastic cuffs and ankles. PAINT SHIELDS A ready-made guard to keep paint off an adjacent surface. Often used when painting window frames and skirting boards. The shield is held against the glass or wall to protect it. An alternative to masking off areas and a handy tool that can be cleaned and reused. PAINTER’S TAPE An alternative to masking tape. Masking tape can be hard to remove and can take some of your new paint with it, which means touching up. Bloc-it painter’s tape is designed to be easily removed and leave a clean, crisp edge every time. It also prevents any paint from seeping through. Tape is an essential item when doing paint effects or masking between two colours. POLYCELL BRUSH CLEANER Although more expensive than turpentine (the regular solvent cleaner), these powerful solventbased cleaners are easily rinsed off with water. To clean a brush used with oil-based paint, work a small amount through the bristles, then rinse with water until the water runs clear. Hang the brush (or roller) up to dry. Allow dirty cleaner to stand and separate. The clear top layer can be reused but the sediment must be disposed of correctly (see page 14 ). PAINT PADDLES/ STIRRERS Most paint needs stirring before use, the exception being nondrip enamel. Always read the instructions on the tin before stirring, then stir with a clean, flat, smooth piece of wood with holes drilled through it, or a ready-made paint stirrer, which is the reusable option. Or use a drill attachment stirrer. DROP CLOTHS OR PLASTIC SHEETING It’s important to protect your floors, furnishings and trim when painting. Flecks of paint can go everywhere, even when you are being careful. Drop cloths are for protecting floors from drips and spills and are positioned right up against the walls or under the ceiling being painted. Plastic sheeting is slippery so it’s not that good to use under a ladder or underfoot, but it is handy for wrapping around furniture, taping over doorways and taping to skirting boards to save you lots of cleaning up afterwards. PAINT PAILS/ KETTLES It’s always advisable to decant paint into another container rather than use it straight from the tin. This ensures that any bristles that fall out of your brush and any dirt that it picks up won’t contaminate the entire tin. A ready-made paint pot is recommended. Spare paint pots come with magnetic brush holders that save you from damaging your brushes by standing them in the paint, disposable liners which make cleaning them much easier, and Velcro straps for attaching them to your ladder. SAFETY GEAR • Safety glasses • Latex gloves (especially with solvent-based paints) • Short scarf or cap (to cover your hair) • Overalls 5 PAINTBRUSHES Always have a project in mind when choosing a paintbrush as it will help you pick the best one for the job. If you are stocking your workshop, choose quality brushes as they will last you a lifetime. Paintbrushes can be used with all types of paint as well as with lacquers, varnishes and oils. In addition to painting, varnishing or sealing whole objects, such as doors, walls, furniture and toys, they can be used for cutting in (painting the edges, corners or trim) when you roller a wall. It is possible to paint a wall itself with a brush, but this is uncommon as rollers do the job much better. QUALITY VS • Quality brushes improve with use as their loose bristles are lost and the tips become rounded, enhancing paint pick up and release. • You also won’t have to load the brush with paint so often as quality brushes have a high loading capacity. CHEAP BRUSHES • Cheap brushes are acceptable when you’re buying an all-rounder brush to use only a few times, but they tend to drop their bristles into your paint and onto your newly painted surface, and they don’t spread the paint evenly. • If the ferrule (the metal binder between the handle and bristles) is made of stainless steel, it won’t ever rust. • They also have fewer bristles for their width, which affects their paintloading capacity, and the bristles are often anchored with an adhesive which deteriorates with use, which means you lose bristles every time. • Quality brushes also hold their shape and form over long periods, but you do need to clean, look after and store them correctly. • Projects where cheap brushes are needed include applying wood preservatives to rough timber or for removing dust after sanding. WHAT SIZE BRUSHES TO CHOOSE 6 < 25 mm Small jobs, touch up work on toys, chairs, interior trim 38 mm Furniture, small panels, window frames, downpipes 50 mm Small to medium-sized projects, including doors, table tops, cabinets, gutters 75 mm Medium to large projects, including floorboards, skirting, fence posts, cupboards, outdoor furniture 100 mm < Large flat areas such as walls, floors, ceilings, roofs CUTTING IN BRUSH NATURAL BRISTLE BRUSHES STORAGE Store brushes by hanging them, lying them flat or propping them upside down in a jar. The bristles need to be protected, so never store brushes with pressure on the tips or sides of the bristles. These are narrow and angled so as to give a smooth line. They are used for painting around fixtures and areas where a roller or larger brush would be unweildy. Quality cutting in brushes have a convex chisel shape to produce smooth even lines. Natural bristle brushes are often used with varnishes, oils, fibreglass, glues and resins. Ones with unpainted wooden handles are meant for resins and solvents that would dissolve any paint on the handles. Natural bristle brushes are the best for oil-based paints (but not latex paints, which need synthetic bristles). If a paint requires a particular type of brush or roller, it will say so on the tin. 7 FOAM ROLLERS ROLLERS Ideal for covering large areas such as walls, doors and ceilings quickly and smoothly. Foam rubber or mohair rollers are best for smooth surfaces while lamb’s wool or nylon pile rollers are best for textured ones. Rollers are always used with a roller tray. ROLLER TRAY splatter and are virtually lint-free. Mohair rollers are also suitable for solvent-based enamel paints, unlike most rollers. These are general purpose rollers, used for smooth and lightly textured surfaces, but they do not give a high-quality finish. Some can be used for paint effects. MINI FOAM ROLLERS LAMBSWOOL ROLLERS Holds the paint for loading rollers. Some new trays are designed to be used on a ladder (vertical) and you can also get deeper ones to use with thicker rollers. SHEEPSKIN ROLLERS Wool has good paint pick up and release, which means less splatter and a long lifespan. It is also suitable for varnishes, enamels and other solventbased products. SYNTHETIC ROLLERS Suitable for all types of paint and for covering small to medium areas. Handy for spots where normal rollers can’t fit (behind pipes etc). STORAGE Professionals tend to use these as they hold more paint and are easier to work with - less splatter and fewer fibres shed. MOHAIR ROLLERS These have a fine nap and give a quality finish on smooth surfaces. They produce less 8 There are thick-nap synthetic rollers for rough and textured walls, and fine-nap rollers for smoother surfaces. They are often the most costeffective rollers. You also get combination rollers with a mix of natural and synthetic fibres. Hang up rollers when not in use to prevent the pile from being flattened, but ensure they don’t lean against a wall or other flat surface. EXTENSION POLE Extension poles enable you to paint ceilings and the tops of walls without using a ladder or scaffolding. Most rollers have hollow handles into which you can screw one. They also speed up painting as you don’t have to keep climbing up and down the ladder to reload your roller or move the ladder when painting a ceiling. PAINTING VOCABULARY A few painting terms you might like to know BLISTERING BUBBLES hot day), or the paint was stretched too far during application. EXTREME CRACKING The name for the bubbles that sometimes form while paint is drying. They can be caused by moisture in the wood, adding a second coat before the first has dried properly, or applying paint to a surface that’s too hot or greasy. Refers to the bubbles in newly applied paint. Can be caused by excessive rolling or vigorous mixing which resulted in trapped air. CHALKING The formation of powder on a top layer of paint. Often caused by the paint breaking down through weathering. Also called crocodiling. Could be because the undercoat is incomparable with the topcoat or because the topcoat was applied before the previous coat had dried completely, or because of loss of paint elasticity due to extreme temperature fluctuations. CRACKING OR FLAKING MUD CRACKS When a newly painted surface cracks, either the surface was incorrectly prepared, the paint dried too fast (e.g. on a very Deep irregular cracks that appear in paint that was applied too thickly or when there are coats of different thicknesses. BLUSHING When lacquer dries cloudy instead of clear. Caused by moisture in the lacquer as a result of the solvent evaporating too quickly. 9 Fired Earth A ll-in-One is a combined plaster primer, seale r and undercoat, w hich means you on ly have to apply one coat of it and nothing else before your topcoat. Paints and primers TYPES OF PAINT ACRYLIC Fast-drying, water-based paints that can be used on most surfaces over a suitable primer. Commonly used for large areas, such as walls and ceilings. The gloss versions are never as glossy as their enamel equivalents. Acrylics are often chosen because they are easy to work with, can be cleaned off brushes etc with water, and are quick drying. 10 ENAMEL Oil-based paints, generally reserved for timber and metalwork such as doors, architraves, window frames and burglar bars. Produce a tough, glossy finish that’s easy to clean and great for areas which sustain small knocks, such as doorways. However, enamels take longer to dry between coats (often overnight), and it’s harder to clean the brushes and rollers because you need a solvent. UNDERCOAT Prepares the surface for the topcoat. Designed with the type of surface in mind. Assists with paint adhesion, improves topcoat coverage and ensures a good finish. Often used when painting a water-based paint on top of a solvent-based one. PAINT FINISHES MATT FINISH Modo Pink to White Ceiling Paint goes on pink before drying white, thereby making it easy to see if you’ve missed a spot during application. No need for a primer either, just prep, apply an undercoat and paint on your Pink to White. PRIMERS A finish that doesn’t shine. Often used for ceilings and irregular wall surfaces (except in kitchens and bathrooms, where a semi-gloss or gloss paint is usually chosen for its ability to withstand frequent washing). Although not popular, solvent-based paints with a matt finish are occasionally found. SATIN AND LOW SHEEN HIGH GLOSS Ideal for rooms with a lot of traffic and need to be moisture, dirt and grease resistant, such as bathrooms and kitchens. Gloss finishes highlight imperfections while matt finishes hide them. So if painting a wall with a shoddy plaster job, make sure you choose matt paint. A primer seals the surface to be painted and binds the paint onto it. It is one of the most vital steps in the painting process. Different primers are needed for different surfaces. For interior walls you need a plaster primer, for wood, a wood primer, and for metal, a metal primer. Primers can also be used on surfaces that defy cleaning. BONDING LIQUID Used on friable and highly porous surfaces (such as raw brick, weathered paintwork, lime-washed walls and filled cracks) to ensure the paint sticks to them and doesn’t flake after drying. Sometimes referred to as eggshell. Recommended for most walls. Often easier to clean than matt paints. GLOSS AND SEMI-GLOSS Generally used on windows, doors and other woodwork that’s susceptible to greater wear and soiling as they are hard-wearing and easy to wash. But gloss finishes tend to show brush and roller marks as well as surface imperfections, so preparation needs to be thorough, with all cracks and holes filled in and spot-primed. The paint also needs to be layed off (given final light brush strokes in the direction of the wood grain) if you want a smooth, even finish. With the right primer you can give almost any surface a new look. The important thing is to get rid of any sheen on the old surface as it will prevent paint adhesion. One way of doing this is to dull the surface with superfine 220-grit sandpaper. Give your kitchen a facelift by painting your melamine cupboards and tiles for a fraction of the price of an entire revamp. It’s as easy as clean, sand, prime and paint. 11 The success of your paint job depends on your brush and roller... Using and cleaning brushes and rollers HOW TO PAINT WITH A BRUSH 2 You can speed up paint mixing by buying a mixer attachment for your drill or, if using a wooden paddle, by drilling large holes (20 mm or so) in it. 2 Choose the right size brush. Grip large brushes around the handle and hold smaller brushes more like a pencil. 1 1 Stir the paint with a paint paddle – except for non-drip paint, which you mustn’t stir at all. Mix in any liquid that’s risen to the surface thoroughly by lifting the stirrer as you go. 12 4 3 3 Flick the bristles against your hand to remove any dust, old paint and loose bristles. 4 Wet the brush and squeeze dry (use water for water-based paints) and turpentine for solvent-based paints). This will help the bristles to absorb and release the paint better. 5 5 Dip the brush into the paint to about one-third of the bristle length. 8 8 When using an acrylic, apply the paint in horizontal bands from the top to the bottom of the area, working the paint in all directions as you go. 6 Press the brush against the wall of the tin to remove surplus paint; do not scrape it over the rim as too much paint will come off. or other liquid in which you have cleaned brushes down the drain as it will pollute our water. See page 14. DEFINITION: CUTTING IN 9 9 Before reloading a brush, 7 When using an oil-based enamel, apply three vertical strips, leaving gaps just narrower than the width of the brush between them. Then, without reloading the brush, brush it horizontally across the strips to work the paint into the gaps. Then, using the same brush but without reloading it, apply light vertical strokes, ending on an upstroke. Continue with the next section in the same manner. 11 Never throw paint, solvent Keep toothpicks on hand to remove any bristles that end up in your paint. Remove, then brush over the area. Doing this while the paint is still wet is the easiest way of remedying the problem. 6 7 11 wipe it on the edge of the pot to remove any paint that has worked its way up the bristles and handle. The term for painting the edges of a wall next to doors, ceilings, fixtures or a different colour -- all the spots that are hard to paint properly with a roller. You can use a normal paintbrush for this or an angled brush, but there are also ready-made cutting in brushes designed to produce clean, smooth lines. Green hint 10 10 When finished, clean your Never allow the water in which you are cleaning brushes or rollers to run down the drain. This is harmful, pollutes our water and is often illegal. See page 14. brush immediately. 13 HOW TO CLEAN A BRUSH AFTER PAINTING WITH ACRYLIC 1 2 3 Gently scrape excess paint from the brush onto cardboard or absorbent paper. Using the back of a putty knife, work from the heel (the base of the bristles) to the tip. HOW TO CLEAN A BRUSH AFTER PAINTING WITH ENAMEL (SOLVENT BASED) 1 Gently scrape excess paint from the brush onto cardboard or absorbent paper. Use the back of a putty knife and work from the base of the bristles to the tip. Wash water-based paint out of the brush under a running tap over a bucket. Rub a little soap or washing-up liquid into the bristles and rinse in clean water. Shake brushes vigorously outdoors to get rid of excess water. 4 Let the brush air dry completely. 5 Slip a loose rubber band over the tip of the bristles to hold them together and to keep the brush in shape for future use. Alternatively, wind some old newspaper or paper around the damp brush a couple to times and leave to dry - the newspaper will keep the bristles aligned while in storage. 2 Work a small amount of Polycell Brush Cleaner through the bristles in an old tin or glass jar. 3 Rinse the brush with water until the water runs clean. 4 All the brushes benefit from a final wash in soap and a rinse in clean water, but it’s not strictly necessary. 5 Shake brushes vigorously to get rid of any remaining cleaner. It’s best to do this in an old paint tin or bucket as brush cleaners are not good for the environment or plants. 6 Let the brush air dry completely. 7 Slip a loose rubber band over the tip of the bristles to hold them together and keep the brush in shape for future use. Alternatively, wind some old newspaper or paper around the damp brush a couple of times and leave to dry the newspaper will keep the bristles aligned while in storage. DISPOSING OF THE CLEANING WATER DISPOSING OF THE CLEANING SOLVENT This is the correct way to minimise the impact on our planet and its valuable water resources. If you have a container of dirty Polycell brush cleaner or turpentine, here’s how to get rid of it without harming the environment. NB: It’s illegal in most municipalities to throw this solvent down a drain. • Let the paint settle in the bucket. Overnight is best. • Pour the clear water down the drain. • Scrape the paint sediment into old newspaper and add to your domestic rubbish. • Never throw paint or liquid in which you have cleaned brushes down a drain. 14 • Allow the paint to separate from the solvent in a closed container. This might take a few days. • Pour off the clear top layer of solvent for reuse and seal in a clean, airtight container. • Leave the remainder to dry out in an old tin or jar, then add to your domestic rubbish. HOW TO PAINT WITH A ROLLER 5 1 1 Thoroughly stir the paint with a flat paint paddle. 3 3 Wet the roller and squeeze dry (use water for water-based paints and turpentine for solvent-based paints). This will help the pile to absorb and release the paint. 5 Dip the roller into the paint and then run it lightly on the ridged part of the tray. This will spread the paint evenly on the roller. Line your paint tray with aluminium foil or cling wrap so you don’t have to clean it when finished. Just throw away the liner. 6 6 When painting a wall, place 2 2 Use a brush to cut in the edges around the doors, windows, skirting, interior corners and where walls meet the ceilings or a cornice. 4 4 Fill about one-third of a roller tray with paint. Do not overfill or it will spill. the roller in the middle of a run (strip of wall about a metre wide) and work it up to the ceiling and then down towards the floor in a W pattern. This will distribute the paint. Then, without reloading the roller, work it horizontally across the area to fill in the gaps. 15 HOW TO CLEAN A ROLLER 1 Scrape as much paint as possible from the roller back into the paint tray using a paint stirrer. 7 7 Do not stretch the paint out. When it starts to run out reload the roller and continue applying in a W pattern. 2 Run the roller over the ribbed part of the tray and then over sheets of newspaper to remove excess paint. 3 Remove the roller from the handle, if possible. For water-based paint, wash under running water (over a bucket), working the paint out with your hands (wearing latex gloves). More than one bucket might be necessary. Continue until all the paint has been washed out. 8 8 Overlap strokes while paint is 4 For solvent-based paint, work a small amount of Polycell brush cleaner through the roller pile, then rinse over a bucket until the water coming off is no longer milky. 5 Shake roller vigorously outdoors. 6 Air dry before storing. 7 Store by hanging so you don’t damage the nap. 8 Never throw paint residue down the drain. (See page 14 for disposal). wet for a smoother finish. End each section with a light roll to even out any lines left by the roller. 9 9 Clean roller immediately after use. 16 Drill small (±2.5 mm) holes in the groove around the rim of the paint tin to allow any paint in it to drain back after decanting into a roller tray. As paint doesn’t store well in a tin that’s no longer airtight, do this only if you intend using all the paint. Green hint Large amounts of turpentine are needed to clean brushes and rollers properly. However if you choose a brush cleaner like Polycell, only a small amount is needed; the last bit of washing happens with water. So brush cleaners are a greener option than turpentine. Never leave brushes or rollers to soak in water or solvent as it will damage the integrity of the bristles or pile. Preparing the surface HOW TO PREPARE THE SURFACES 1 Remove all door locks and other fittings. 2 Check for damp (see page 19) and remove the cause. Wait for about a month for the wall to dry out completely before painting. 3 4 To remove any mildew, clean with a solution of water, bleach and a mild ammonia-free detergent. Wash walls and mouldings down thoroughly with warm water and sugar soap (clean walls require 20% less paint). Make sure you rinse off the sugar soap properly (use rubber gloves to protect your hands from this alkaline product). Clean around electrical outlets and switches with a damp cloth and sugar soap. Make sure no water gets onto your electrical fitings; ‘rinse’ by wiping with a clean damp cloth. 5 Remove any loose or peeling paint with a scaper and feather the edges with sandpaper. Try not to gouge the surface with the scraper as you will have to go back and fill in the marks. What you will need: - Canvas drop cloths - Plastic drop cloths - Detergent/sugar soap and warm water - Clean rags and sponges - Bloc-it painter’s tape - Paint scraper SAFETY GEAR • Dust mask • Safety glasses • Rubber gloves • Overalls - Spatula and filling compound - Hammer (if needed) - Sandpaper, sanding block - Plaster primer - Paint tin opener (or screwdriver) - Paint stirrer/paddle 17 6 Apply filler to any large uneven areas or gashes in the old paint. Do the same with nail holes and cracks. Level the areas you have filled and, once dry, sand smooth. (Refer to the Cracks section). 7 Sand walls lightly, including the corners, to smooth out any lumps and bumps with fine-grit sandpaper. After sanding, be sure to brush and vacuum away the dust. Surfaces must be free of all dirt, crayon (wax) and grease (try washing or, alternatively, sanding these away) as they could bleed through the paint if left. 8 9 Tape over light switches and plug points (or, better yet, remove the cover plates). 10 Mask all doors, windows and skirting boards with painter’s tape so no paint gets on them, then cut in up to them. 11 Spot-prime any newly patched areas on the walls. Ask a Builders to help you choose the right primer for your preparation coat. 12 Apply an undercoat followed by your topcoat. Start at the floor and move towards the ceiling when cleaning a wall with sugar soap. The grimiest part is usually near the ceiling so cleaning it last means you won’t drag the dirt across the rest of the wall. 18 CRACKS All cracks should be opened up and filled before painting. 4 4 Sand flush with the wall. 1 1 Sand around the crack and open it up with a scraping knife. Vacuum all the dust out or use a clean wet rag to pick it up. Allow to dry. 2 2 Apply a coat of plaster primer and allow to dry. 3 3 Mix filler and fill the crack with it using an X pattern. Allow to dry. 5 5 Paint with plaster primer to ensure your undercoat or topcoat adhere well. Use a 100 mm paintbrush or an old dustpan brush dipped in warm water and sugar soap to wash a textured wall in preparation for painting. Rinse well to neutralise the soap. Write down the name of the paint (its colour), the manufacturer and batch number with a permanent marker on the inside of the light switch cover. Should you repaint, you will then be able to match it closely, if not exactly. THE DAMP ISSUE Three types of damp problems occur with walls; rising damp, penetrating damp and condensation. RISING DAMP leaking shower seeps through to the ceiling of the room below, or when water from a leaking gutter runs down a wall. Damp patches then occur on the wall or ceiling and attract mildew. CONDENSATION Caused when groundwater moves up through the brickwork and affects the plaster and paint. When soil lies up against a wall, water can also seep through the bricks sideways. This is usually noticeable as brown stains where the wall and floor join. Other signs that you have rising damp are soft, crumbly plaster and peeling paint. PENETRATING DAMP The moisture in humid air can condense on wall surfaces. Where this is ongoing it encourages mould to grow on and stain the surface. The problem, which often affects bathrooms, can be cured with proper ventilation. SOLVING IT When water drips constantly onto a painted surface, the paint weathers faster than normal and can allow the water to penetrate the underlying surface. Examples of this are when water from a The solution to damp problems is to remove the cause. Begin by identifying the cause. Whether it’s a leaking gutter, air conditioner outlet, geyser overflow or soil against bricks, you have to fix it. Air conditioner outlets and geyser overflows can be routed further away through tubing or piping, gutters can be fixed and showers can be waterproofed. If the problem is a wall with soil against it, consider stepping the soil back permanently, or exposing the wall and waterproofing it properly before replacing the soil. Rising damp might require more drastic action, such as routing groundwater away from foundations. In such cases you’ll need to consult a damp/ waterproofing specialist. Before repainting a wall that had damp issues you must take steps to prevent any moisture still trapped in the bricks from affecting your new paintwork. Scrape or sand the wall back to the plaster and wash with sugar soap. Repair any cracks in the plaster with Tite waterproof crack filler, then apply three coats of thinned Dampseal, as per the instructions. Sand the surface smooth and paint with plaster primer and an undercoat before finishing with a topcoat. 19 Painting your ceiling When painting an entire room, first paint the ceiling, then the walls and lastly the woodwork and trim. Any splashes and splatters will then land on areas still to be painted. 1 PERSON 1 3 SKILL 6 HOURS HOW TO PAINT YOUR CEILING What you will need: - Drop cloth and plastic sheeting - Paint stirrer - Modo Pink to White Ceiling Paint - Cutting in 1 1 Prep by washing and rinsing the surface to get rid of any grease. Scrape off any flaking paint, fill in any cracks and sand down any lumps and bumps. 20 brush (50 mm) SAFETY GEAR • • • • Safety glasses Cap to protect hair Overalls Latex gloves - Paint tray - Roller - Extension pole - Ladder 5 2 2 If you have cornices, they will need to be cut in completely as your roller will not be able to adequately paint them. Extend the cut-in about 100 mm onto the ceiling. 3 3 If you don’t have cornices, then cut in where the ceiling and walls meet, extending the paint about 100 mm onto both the walls and ceiling to ensure no gaps will be left after you’ve painted the walls. 4 4 Using an extension pole, roller on a thin coat of Modo Pink to White Ceiling Paint. It will show up any spots you’ve missed as the paint goes on pink before drying to white. A thin coat will ensure there are no drips and runs. Work from one side of the ceiling to the otther, moving backwards to avoid too many splatters landing on the area you’ve already painted. 5 5 Let the paint dry completely. Cut in cornices/corners again and apply a second coat to the ceiling. This is where Modo Pink to White is invaluable as the second coat will be going pink onto an already-white surface. 21 Painting interior walls HOW TO PAINT YOUR INTERIOR WALLS 1 PERSON What you will need: 3 1 SKILL 6 HOURS 5 - Paint stirrer (drill attachment or flat wooden paddle) - Paintbrush and pail - Small touch-up paintbrush Tint your undercoat to a lighter shade of the topcoat you intend using as it will ensure better coverage and colour intensity. 1 1 Prep your wall (clean, mask, fill, sand and prime). 22 SAFETY GEAR • • • • Dust mask Safety glasses Rubber gloves Overalls - Paint roller and tray - Undercoat - Interior paint Fired Earth Ultimate - Ladder and extension pole - Bucket for cleaning - Painter’s tape 4 Fix a dry paint drip by sanding it smooth, wiping it with a damp cloth and touching up. 4 Roller your wall from right to 2 left (the reverse if you are left handed) as you are less likely to accidentally touch and mess up an area you’ve already painted with your hand or elbow. 2 Cut in and roller on your undercoat. 5 5 Allow each coat to dry before applying another coat. Two coats should be sufficient for a good finish, but if you’re painting a light colour over a dark one, more might be necessary. 7 7 Remove masking. If the paint starts to lift, lightly score along the edge of the tape before continuing. Touch up where paint was pulled off. 3 3 Using a paintbrush, cut in the door and window frames, any fittings, skirting and the ceiling with your topcoat. Wrap the brush in clingwrap to prevent it from drying out before the next cutting-in session. 6 6 Shine a strong light onto the wall to show up any missed or light spots. Insert the handle of your roller through a tinfoil or paper plate to stop paint dripping and flicking onto your head when painting above it. 23 Trim refers to windows and window frames , doors and door frames, skirting boards and deck rails. Painting your trim with enamel Traditionally, woodwork in the home is painted with enamel because of its glossy finish and ability to withstand knocks. The end choice of colour and type of paint always lies with you. What you will need: PAINTING A WINDOW - Drop cloth Because windows have many surfaces and extra effort is required to keep the glass clean, painting a window takes longer than you think. As you’ll probably want to close your windows at night for security reasons, start work as early in the day as possible. HOW TO 1 PERSON 1 3 SKILL 7 HOURS 5 - Bucket, sponge and sugar soap - Screwdriver - 38 mm cutting in brush - Paint shield - Bloc-it painter s tape - Sanding block SAFETY GEAR - Fine-grit sandpaper - Steel wool - Mineral turpentine - Primer (if necessary) 1 1 Lay down a drop cloth to protect your floor. 24 • Safety glasses • Latex gloves • Dust mask for sanding - Modo enamel paint - Polycell brush cleaner 2 2 Prep your windows and frames by washing them with sugar soap. Rinse well and let dry. 5 6 Apply primer or stain sealer where necessary to any bare wood. 7 7 A 38 mm trim or cutting in brush is a good choice. If you have wider or thinner surfaces, then choose a different size. A cutting in brush with an angled edge will be best for painting the parts closest to the glass. 3 3 Use a scraper or sandpaper to remove any loose paint. 6 6 Don’t stir the paint as this 4 4 Remove any fittings and fill any holes with wood filler. will break down the non-drip compound. If the paint has separated, then stir it very slowly and stop as soon as it’s mixed well. 8 8 If you have casement windows, open them halfway, mask the glass with tape and mask off the walls around the window. 25 9 9 Paint in the following order: 1 cross-bars and rebates (where the glass meets the wood); 2 top and bottom cross-rails; 3 hanging stile and hinge edge; 4 meeting stile; 5 frame 10 10 Work from the glass outwards. 12 12 Paint the architraves and the window frame. 13 13 Prep for a second coat (optional) by sanding the first lightly. Dust off or vaccum and apply the second coat the same way as the first. 11 The brush strokes should follow the pattern of the joinery - so make your vertical strokes cut off the horizontal ones. 26 11 Do not apply too much paint in one coat as it will run and take longer to dry. You can close windows when the paint is dry to the touch by rubbing talc on the meeting surfaces or putting cling wrap on areas likely to stick. PROTECTING THE GLASS You can use painter’s tape, petroleum jelly or lip balm to protect window glass from paint. Or use a ready-made masking shield, held in place as you paint. Leave a 2 mm gap between the frame and mask/shield to allow a tiny bit of paint onto the glass. This will seal the frame and is a great trick for external windows as it makes both the paint and frames last longer. If your technique with a cutting in brush (an angled brush designed to give good clean edge if you have a steady hand) is good, then you might not have to protect the glass at all. The trick is not to overload the brush with paint and to ease it towards the glass. 14 14 Remove the painter’s tape and scrape off any excess paint with a scraper. 15 15 When paint is dry, reattach the fittings. The parts of window frames right next to the glass can suffer from mould. Use a fungicide wash or bleach (diluted 1:3 with water) to get rid of the problem. Always wear gloves and safety glasses with these products. 16 16 If a window sticks at all, sand where it’s sticking lightly until it closes easily. Remove drips on metal (if you left your fittings on) with steel wool dipped in mineral turpentine. Alternatively, remove fittings, put each in a plastic bag, reattach and pull the bags tight. Paint right up to the plastic and when dry, remove fittings, discard bags and reattach fittings. 27 PAINTING A DOOR Prepare door, doorframe and architrave at the same time. Wash to remove grease (sugar soap is excellent but must be rinsed off well afterwards). Fill any cracks or nicks with filler, sand level when dry and prime with bonding liquid. Sand the sheen off the surfaces with 220-grit sandpaper to ensure the new paint bonds well with them. Remove any handles and other fittings. Jam the door between two doorstops to prevent it from closing and trapping you inside. Always decant oil-based paint before use, resealing the tin to prevent what’s left in it from drying out and debris from dropping into it. HOW TO 1 PERSON 3 1 SKILL 7 HOURS What you will need: - Modo enamel paint - Paintbrush and pail - Sanding block 1 1 Start with the door (always leave the frame till last), working from top to bottom and left to right (if you are right-handed). It will feel easier this way and you shouldn’t get as much paint on your elbow. Paint the door all in one go or it will show where you took breaks. Paint small sections at a time, blending them well into one another. Remember to paint the top and bottom of the door - this is often forgotten. 28 - Fine sandpaper - Painter’s tape - Polycell brush cleaner - Plastic sheeting 5 4 2 2 Load the brush, dipping the bristles about 1/3 of their way into the paint. Paint three vertical strokes next to each other, leaving a gap between them just narrower than the brush width. 4 When the brush is almost dry, go over the section lightly with vertical strokes, stopping on an upward stroke (this is called laying off and will give the work a quality look). 5 3 3 Without reloading the brush, work across the strips to fill in the gaps and smooth the paint. 5 Paint the next section to the side of the first, working the new paint into the previous section. Go right across the door before moving down, but make sure the paint you are working the new section into is still wet, otherwise the door will be spoilt by a dry paint line. 29 PAINTING SKIRTING PAINTING A PANELLED DOOR 2 1 Paint inside panels first Cross-bars and centre struts moving down When painting skirting above a fitted carpet, make sure you don’t load too much paint onto the brush, then start from the top and move slowly down. This will reduce the chance of drips getting on the carpet. 3 Vertical side pieces 4 Top and bottom edges Paint the inside panels first then the cross-bar at the top, followed by the vertical centre strut and the middle and bottom cross-bars. Finish with the vertical side pieces. The order for the frame (not shown) is top cross-bar and then the two side pieces. Check for drips and runs and brush them out before the paint dries. 30 Paint your skirting last. First, vacuum the floor well so your paintbrush won’t pick up any dirt or fluff from it. Next, mask the floor, or use a paint shield as you go, to protect your flooring or carpet. To paint or seal the bottom edge of a door (without taking it off its hinges), use a strip of carpet as a paintbrush. Slip a sheet of newspaper under the door, apply paint or sealant to the pile of the carpet, slide it under the door and work it back and forth to coat the bare wood. Waterproofing a shower Sika Cemflex is designed for waterproofing showers, balconies, retaining walls and fish ponds. You add cement and water to it to create a waterproofing slurry and then use it in conjunction with a membrane. HOW TO 1 PERSON 1 3 5 SKILL 8 HOURS SAFETY GEAR • Safety glasses • Gloves What you will need: 2 1 1 Remove old coating and prep wall as for painting. It is important to remove all dirt, oil, grease and flaking, bubbling or lifting paint to create a clean, sound surface. 2 Mix Cemflex with equal quantities of water. Add the correct amount of cement (check the table provided) and mix to a lump-free slurry. Use immediately, ensuring the cement stays in suspension throughout by mixing it periodically. - Bucket - Block brush - Trowel - Black cement (Portland slag cement) - Silka Cemflex - Membrane 31 3 3 Prime the surface by painting it with a generous amount of slurry. 5 5 Remove all creases and bubbles before overcoating with slurry. 6 6 Allow to dry and then apply a final coat of slurry. 7 Clean tools immediately with warm water. 8 Protect the area from sunlight and wind for 24 hours and allow 2 days for the waterproofing to cure before use. TAKE NOTE 4 4 Saturate the membrane with slurry and immediately lay it onto the surface. (Large pieces of membrane are hard to handle but small pieces have to be overlapped, so you end up using more membrane.) 32 Portland blast furnace cement is not suitable as a substitute for Portland slag cement when mixing Sika Cemflex.
