Requirements concerning masonry mortars. Part 1: Plastering mortar. •They can be divided in terms of manufacturing concept: - mortars of specified properties - mortars of specified composition •The most important standard division of mortars classifies them in terms of properties and/or mode of application. So, there are plastering mortars: - of general use (GP) - light (LW) - coloured (CR) - for single layer plasters (OC) - renovation plasters (R) - thermo insulating plasters (T) The above division allows to select the mortar for the needs of a given investment practically unambiguously. Of course, you always have to consult the manufacturer of the material of which the wall has been built. •Depending on the quality of the finishing coat, plasters are divided into categories from 0 to III. All plasters manufactured by ATLAS are of the highest finishing category - III. They are characterized by very smooth and even surface required of this grade of plasters, without cracks, efflorescence, or air bubbles. Classification of plastering mortars Plasters are present on every building. They are manufactured from various raw materials, which results in various parameters in application. The highest requirements are set for façade plasters having a few important functions. First of all, they are to protect the external walls from adverse effects of weather conditions and secondly - to make the façade more beautiful. •Traditional plaster as the final finishing Proponents of traditional solutions often leave the façade finished with grade III plaster and limit themselves only to painting it. This is also done by people whose houses are exposed to intensive soiling - dirt does not “cling” to smooth façade as much as a structural one. •Traditional plaster as a substrate for thin-coat render Thin-coat renders require even substrate and this can only be obtained by the application of traditional cement or cement-lime plaster as the substrate. The ready to use ATLAS plastering mixes provide very good technological parameters and allow machine application. The kind of mix must be properly selected for the type of the substrate, i.e. the wall that we want to plaster. 146 www.atlas.com.pl PLASTERING MIXES Plaster selection • • • particularly recommended for that purpose • can be used for that purpose Type definition: GP - general purpose LW – light-weight OC – of specified properties Mortar type PLASTERING MIX ATLAS CEMENT SCRATCH COAT REKORD KB-TYNK LIGHT-WEIGHT MACHINE APPLIED CEMENT-LIME PLASTER GP GP OC LW LW ••• Place of application Indoors ••• ••• ••• ••• Outdoors ••• ••• ••• ••• Substrate type Ceramic ••• ••• • • ••• Lime-sand ••• • • • ••• Concrete ••• ••• ••• • • • • ••• ••• ••• ••• ••• • ••• ••• Cellular concrete Application Manual ••• ••• Machine • • •* ••• Plaster parameters Colour grey grey white grey grey Grade 0-III - III 0-III 0-III CSII 1.5 – 5.0 N/mm2 CSIV ≤6.0 N/mm2 CSIII > 6.0 N/mm2 CSI 0.4 – 2.5 N/mm2 CSII 1.5 – 5.0 N/mm2 6 - 30 mm ca. 4 mm 1 - 10 мм 2 - 8 mm 5 - 30 mm ca. 20 kg/m2 ca. 8 kg/m2 ca. 15 kg/m2 ca. 15 kg/m2 ca. 11 kg/m2 Compressive strenght Thickness Consumption per 1 cm of thickness * Machine-applied plaster is manufactured as a variant of ATLAS PLATERING MIX - the packaging of the product marked with letter M. Product Data Sheets Catalogue 147 PLASTERING MIXES ATLAS PLASTERING MIX traditional cement plaster of category III • manual or machine application • high plasticity • high strength, CS II • layer thickness 6 – 30 mm • for plastering walls and ceilings CLASS OF REACTION TO FIRE ACC. TO THE EUROPEAN STANDARD PRODUCT CONFORMS WITH THE EUROPEAN STANDARD Use Technical data Double layer plaster of category 0-III – the plaster consists of two layers: the “initial scratch coat” and the “surface floating coat” (it can be additionally covered with a finishing coat layer made of white, cement - based ATLAS REKORD finishing coat). Suitable for manual and machine application – the mix is available in two versions: for manual or machine plastering (packages additionally marked with letter M). ATLAS PLASTERING MIX is manufactured in the form of dry mix of cement binder, quartz fillers and improvers of the highest quality. Types of substrates – ceilings and walls made of bricks, blocks, hollow bricks and other similar ceramic or silicate materials; surfaces of concrete, aerated concrete, chip-cement boards, cement and cement-lime plasters. Properties High strength: CSII category (1.5 ÷ 5.0 N/m2). The mortar can be supplemented with so-called anti-frost additives allowing to carry out works at lowered temperatures, i.e. below +5°C – the new temperature range of mortar application, the way of its preparation (especially the adjustment of the amount of water added), principles of carrying out works and the mortar setting conditions must be accepted according to the guidelines of the manufacturer of the additive. The amount of the anti-frost agent depends on the content of cement in the mortar – the proportion of cement to fillers in ATLAS PLASTERING MIX is at 1:4. Note. The manufacturer of the mortar is in no way responsible for the effects and the quality of the anti-frost agents used.

Hammer off poorly adhering elements and remove loose pieces using a steel brush. Contacting edges of particleboards should be reinforced prior to plastering using strips of stainless steel mesh. Protect the corners and edges of window and door reveals with galvanized steel profiles. If necessary, use ATLAS UNI-GRUNT priming emulsion to reduce substrate excessive absorption. Mortar preparation Pour the mortar from the bag into a clean container with the suitable amount of water (see Technical Data for proportions) and mix using a drill with a mixer (or in cement mixer) until homogenous. In the case of machine application - in a plastering unit. Leave the mortar to rest for 5 minutes and then remix. The mortar is ready to use directly after mixing and should be used up within ca. 4 hours. Plaster application Apply the plaster in two layers. In order to obtain even plaster surfaces, use plastering boards. They can be fixed mechanically or by embedding in the mortar (mesh profiles). The first plastering stage is the execution of the “initial scratch coat.” After it sets (but still before hardening), the “surface floating coat” has to be executed. In both stages, the plaster is applied evenly with the use of a trowel (or a plastering unit). Collect the excess of the mortar using a float made of EPS or wood and put back into the container. Fresh plaster surface can be made even with a long rule, using the guide strips. Floating The moment to start floating has to be determined experimentally in order to avoid excessive drying of the plaster. Floating is usually carried out after the application of an additional thin layer of the mortar, corresponding to the grain size of the aggregate. The finishing works must be carried out in accordance with plastering works technology, with the use of tools appropriate for the expected finishing result and the intended use of the plaster. If the plaster is to be the substrate for ceramic facing, it should not be floated at all or coarsely finished. If the plaster is to be covered with gypsum finishing coat, float it with EPS float. Maintenance Ensure appropriate room ventilation during drying. Protect external plasters from drying too quickly, e.g. by sprinkling them with water. Consumption One 25 kg bag is sufficient to obtain 1.3 ÷ 1.4 m2 of 10 mm thick plaster. Important additional information • Adjust the ratio of added water experimentally, following the desired consistency of the mortar, type of substrate and weather conditions. Inappropriate amount of water for mix preparation results in deterioration of strength parameters of the plaster. • Tools must be cleaned with clean water directly after use. Difficult to remove residues of the set mortar can be removed with the ATLAS SZOP agent. • Irritant - contains cement. Irritating to respiratory system and skin. Risk of serious damage to eyes. May cause sensitisation by skin contact. Due to its form - powder, the product may cause mechanical irritation of eyes and respiratory system. Keep out of reach of children. Do not breathe dust. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Wear suitable protective clothing, gloves and eye/face protection. If swallowed, seek medical advice immediately and show the container or label. Follow the instructions in the Material Safety Data Sheet. • The mortar must be transported and stored in tightly sealed bags, in dry conditions (most preferably on pallets). Protect against humidity. Shelf life in conditions as specified is 12 months from the production date shown on the packaging. Content of soluble chromium (VI) in ready-to-use mix - ≤ 0.0002%.

Date of update: 2013-07-01 Painting Plastered substrates can be painted with all façade paints (e.g. ATLAS ARKOL S, ATLAS ARKOL N, ATLAS FASTEL-NOVA and ATLAS ARKOL E). Commencing painting works is possible after 2 ÷ 6 weeks after the completion of plaster application (depending on the kind and colour of the paint). Painting with ATLAS ARKOL S silicate paint and ATLAS FASTEL NOVA silicone paint can start just after the plaster sets, not earlier, however, than after 48 hours (ARKOL S) or 5 days (FASTEL NOVA). Product Data Sheets Catalogue 149 PLASTERING MIXES ATLAS CEMENT SCRATCH COAT scratch coat for 2- or 3- coat plasterwork • improves plaster adhesion to substrate • recommended for cement and cement-lime plasters • reduces the material cost of plasterwork • the highest strength category • manual or machine application PRODUCT CONFORMS WITH THE EUROPEAN STANDARD Use Technical data Creates adhesion layer in two- or three-coat plaster systems – applied directly to the substrate before the application of top coat of cement or lime-cement plaster. Excellent compatibility with ATLAS plastering mortars: -- PLASTERING MORTAR, -- LIGHTWEIGHT CEMENT-LIME PLASTER -- KB-TYNK Reduces the cost of two- or three-coat plasterwork – replaces more expensive plaster types at the scratch coat stage. Hand or machine applied – the use of plastering units speeds up the application considerably. ATLAS CEMENT SCRATCH COAT is manufactured in the form of dry mix of highest quality cement binder, quartz fillers and modifiers improving the plasticity and workability of the material. Types of substrates – walls and ceilings of bricks, blocks, hollow blocks and other similar ceramic or silicate elements; concrete and aerated concrete; cement-bonded particleboard, cement and cement-lime plasters. Properties High strength – the highest standard-specified strength class CS IV (above 6.0 N/mm²) – the scratch coat is a suitable base for top coats, even those of high strength plastering mortars, as it is resistant to shrinkage stress occurring during the setting of mortars of that type. Excellent adhesion to substrate – especially recommended for smooth surfaces or substrates of low absorption capacity; bonds strongly to bricks, blocks etc. The mortar can be supplemented with so-called anti-frost additives allowing to carry out works at lowered temperatures, i.e. below +5°C – the new temperature range of mortar application, the way of its preparation (especially the adjustment of the amount of water added), principles of carrying out works and the mortar setting conditions must be accepted according to the guidelines of the manufacturer of the additive. The amount of the anti-frost agent depends on the content of cement in the mortar – the proportion of cement to fillers in ATLAS SCRATCH COAT is at 1:4. Note.

Insufficiently bound substrate fragments should be hammered off, whereas all loose or crumbling particles should be removed using a steel wire brush. Contacting edges of particleboards should be reinforced prior to plastering using strips of stainless steel mesh. Corners and edges of window and door reveals should be protected using galvanised steel corner profiles. If necessary, substrates characterised by excessive absorption capacity should be primed with ATLAS UNI-GRUNT emulsion.

In the case of machine application - in a plastering unit. Leave the mortar to rest for 5 minutes and then remix. The mortar is ready to use directly after mixing and should be used up within ca. 2 hours. Application of scratch coat The mortar is applied to the prepared substrate manually or mechanically, in a uniform coat, to the thickness of ca. 4 mm. Do not smooth or float the material. Leave the mortar to set initially (ca. 12 hours). After initial mortar setting the top plaster coat can be applied. Maintenance Ensure appropriate room ventilation during drying. Protect external plasters from drying too quickly. Consumption Material consumption depends on the accuracy of surface covering. In the case of scratch coat covering the entire surface the material consumption is ca. 8 kg of dry mix for 1 m2.

Poorly adhering surface elements should be chipped off and loose pieces removed with the use of a steel brush. The substrate should be initially intensively wet before skimming and matt-wet during the mortar application. If it is necessary to reduce the absorbing capacity of the substrate, it is recommended to use ATLAS UNI-GRUNT emulsion. Mortar preparation Pour the material from the bag into a clean container with a measured amount of water (see Technical Data for proportions) and mix it with a slow-speed mortar mixer (or in a concrete mixer) until homogenous. Leave the mortar to rest for 5 minutes and then remix. The mortar is ready to use directly after mixing and should be used up within ca. 2 hours. Plaster application It is recommended to fill large holes in the substrate before applying the plaster coat. Apply the mortar evenly and smooth it with a smooth steel float. When the mortar starts setting, spray it with water and smooth again with the steel float. The mix open time (from the application of the mortar to the final smoothing) depends on the absorbing capacity of the substrate, ambient temperature and mortar consistency. Maintenance Indoors, avoid draughts and ensure proper ventilation and airing of rooms during drying. Prevent outside surfaces from drying too quickly and protect them from precipitation (during and directly after application). It is recommended to sprinkle the surface with water within 1-3 days depending on the conditions. Painting The mortar layer does not require painting. Plastered substrates may be painted with any façade paints (e.g. ATLAS ARKOL S, ATLAS ARKOL N, FASTEL NOVA and ATLAS ARKOL E). In order to improve the surface parameters (reduced soiling and extended durability) you may use a surface hydrophobisation agent ATLAS SILSTOP (it is required to conduct a test in order to check if the surface gets uniform coating). It is possible to commence painting after 2÷6 weeks from the end of plastering works (depending of the paint type and colour). You may start painting with the silicate paint ATLAS ARKOL S or silicone paints ATLAS FASTEL NOVA immediately after the plaster dries up but not earlier than after 48 hours (ARKOL S) or 5 days (FASTEL NOVA). You may apply waterproof insulation of ATLAS WODER type after 2 days. Consumption The average consumption is ca. 1.0 kg of mix/ 1 m² / 1 mm of layer thickness. Important additional information • Adjust the ratio of added water experimentally, following the desired consistency of the mortar, type of substrate and weather conditions. Inappropriate amount of water for mix preparation results in deterioration of strength parameters of the plaster. • Avoid application onto surfaces in strong sunlight. • Protect the surfaces surrounding the work site against dirt. • Tools must be cleaned with clean water directly after use. Difficult to remove residues of the set mortar can be removed with the ATLAS SZOP agent. • Irritant - contains cement. Irritating to respiratory system and skin. Risk of serious damage to eyes.

TO THE EUROPEAN STANDARD PRODUCT CONFORMS WITH THE EUROPEAN STANDARD Use Technical data Recommended for cellular concrete plastering – it is specially designed for plastering walls made of cellular concrete. Suitable for manual and machine plastering – the plaster can be applied manually (with a trowel) or mechanically – with a plastering unit. ATLAS KB-TYNK is manufactured in the form of dry mix of cement, lime, quartz fillers, light mineral aggregate and improvers. Types of substrates – cellular concrete, aerated concrete and walls made of other construction materials with increased insulating capabilities. Properties Light plaster – much lighter than plaster based on traditional aggregate, which makes it easier to apply and float. Contains perlite – volcanic origin aggregate with perfect thermal insulation (very low thermal conductivity coefficient) and sound absorbing properties and very low wet density. Improves thermal insulation of a partition – it is a heat absorbing plaster – limits the possibility of creation of thermal bridging and what follows, e.g. mapping the jointing grid on a cellular concrete wall. High vapour permeability – it is a porous plaster – does not interfere with vapor permeability of the wall made of porous materials like cellular concrete. Low consumption in comparison with traditional plasters.

Insufficiently bound substrate fragments should be hammered off, whereas all loose or crumbling particles should be removed using a steel wire brush. Contacting edges of particleboards should be reinforced prior to plastering using strips of stainless steel mesh. Corners and edges of window and door reveals should be protected using galvanised steel corner profiles. If necessary, substrates characterised by excessive absorption capacity should be primed with ATLAS UNI-GRUNT emulsion. Mortar preparation Pour the mortar from the bag into a clean container with the suitable amount of water (see Technical Data for proportions) and mix using a drill with a mixer (or in cement mixer) until homogenous. In the case of machine application - in a plastering unit. Leave the mortar to rest for 5 minutes and then remix. The mortar is ready to use directly after mixing and should be used up within ca. 3 hours. Plaster application In order to obtain even plaster surfaces, use plastering boards. They can be fixed mechanically or by embedding in the mortar (mesh profiles). The plaster can be executed in one layer or in two layers. In both cases, apply evenly with a trowel or a plastering unit. Collect the excess of the mortar using a float made of EPS or wood and put back into the container. Fresh plaster surface can be made even with a long rule, using the guide strips. Floating The moment to start floating has to be determined experimentally in order to avoid excessive drying of the plaster. Floating is usually carried out after the application of an additional thin layer of the mortar, corresponding to the grain size of the aggregate. The finishing works must be carried out in accordance with plastering works technology, with the use of tools appropriate for the expected finishing result and the intended use of the plaster. If the plaster is to be the substrate for ceramic facing, it should not be floated at all or coarsely finished. If the plaster is to be covered with gypsum finishing coat, float it with EPS float. Maintenance Ensure appropriate room ventilation during drying. Protect external plasters from drying too quickly, e.g. by sprinkling them with water. Painting Plastered substrates can be painted with all façade paints (e.g. ATLAS ARKOL S, ATLAS ARKOL N, ATLAS FASTEL-NOVA and ATLAS ARKOL E). Commencing painting works is possible after 2 ÷ 6 weeks after the completion of plaster application (depending on the type and colour of the paint). Painting with ATLAS ARKOL S silicate paint can start just after the plaster sets, not earlier, however, than after 48 hours. Consumption One 30 kg bag is sufficient to obtain 1.8 ÷ 2.0 m2 of 8.0 mm thick plaster. Important additional information • If plasters thicker than 8 mm are required, apply the mortar in two layers with a dozen-hour technological break necessary for the initial setting of the first layer. In this arrangement, plaster thickness must not exceed 15 mm in total. • Adjust the ratio of added water experimentally, following the desired consistency of the mortar, type of substrate and weather conditions. Inappropriate amount of water for mix preparation results in deterioration of strength parameters of the plaster. • Tools must be cleaned with clean water directly after use. Difficult to remove residues of the set mortar can be removed with the ATLAS SZOP agent. • Irritant - contains cement. Irritating to respiratory system and skin. Risk of serious damage to eyes. May cause sensitisation by skin contact. Due to its form - powder, the product may cause mechanical irritation of eyes and respiratory system. Keep out of reach of children. Do not breathe dust. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Wear suitable protective clothing, gloves and eye/face protection.

TO THE EUROPEAN STANDARD PRODUCT CONFORMS WITH THE EUROPEAN STANDARD 2 Use Technical data Recommended for indoor cellular concrete plastering – in premises with normal air humidity as well as in kitchens and bathrooms. Acts as category III plaster – can be used as traditional double-layer plaster consisting of the “scratch coat” and “surface floating coat”, as well as base coat or finishing coat. Suitable for manual and machine plastering – the use of plastering units allows for fast work progress. ATLAS LIGHT MACHINE APPLIED CEMENT-LIME PLASTER is manufactured in the form of dry mix of cement binder, lime, quartz fillers, perlite and improvers of the highest quality. Types of substrates – substrates of increased thermal insulation capacity: porous ceramics and cellular concrete; concrete, aerated concrete, particleboards, cement and cement-lime plasters. Properties Increased output – due to specially developed recipe, it offers 50% higher output than traditional cement - based plasters. Very good adhesion to the substrate – due to the content of lime, it fills in all irregularities of the wall tightly, seals it and strongly adheres to bricks, blocks, etc. Transfers and distributes strain very well – due to the content of lime, it is a resilient plaster, self-protecting against cracking. Enables increasing the distance between vertical expansion joints – in comparison with plasters based on cement as the only binding agent. Limits the absorptivity of the wall – the tightness of cement-lime plaster protects the wall against water penetration and negative effects of it, e.g. against development of biological corrosion. Perfect workability – the content of lime makes the preparation and the application of the mortar very easy. Easy to apply and float – very convenient to work with, at plastering both ceilings and walls. High water vapour permeability – the plaster coat does not interfere with vapour permeability of the wall executed in porous materials like cellular concrete.

If necessary, substrates characterised by excessive absorption capacity should be primed with ATLAS UNI-GRUNT emulsion. Directly before plastering, the substrate can be wet with clean water and the next step is the application of the preliminary scratch coat. Plaster application Apply the plaster with a plastering unit adapted for work with ready-to-use mixes. Apply the material upon walls using a spray gun, in overlapping horizontal stripes, from top to bottom. The sprayer nozzle should be guided in a smooth motion, at a constant distance from the surface. In case of manual application, apply the material with a trowel. Plaster leveling Even out the applied mortar using an H-shaped plastering rule and leave until the plaster begins to set. Fresh plaster can be smoothed with a long feather edge until a flat surface is obtained. Floating The moment to start floating has to be determined experimentally in order to avoid excessive drying of the plaster. Floating is usually carried out after the application of an additional thin layer of the mortar, corresponding to the grain size of the aggregate.
