Restoration utilizing the Silent Paint Remover and organic linseed oil paint.
Complete Specification
Project: Complete Exterior Restoration. Paint removing and re painting.
This specification is based on utilizing infrared heat as the means of paint
removing with a 98% clean surface as a goal. Organic linseed oil paint is the
prescribed type of paint to avoid future paint failure.
Equipment Requirement per person for the project:
QTY
1.Silent Paint Remover
6 Triangular scrapers
2 Profile scrapers
4 Clapboard scrapers
1 Hands free Track optional pro arm for porches, bay windows and
overhang. Soffit attachment is also available for over head paint removing.
1 Tarp to cover minimum 8’ from the vertical wall along working area.
Sharpening station including gig and blade holder.
Work platforms set up:
Start by installing scaffolding or ladder jacks for the project after the ground below is completely
covered to ensure that as much paint chips and paint dust can and will collected. Using a lift can
work well but may be cost prohibitive and noisy. A sturdy platform with a safety rail is by far the
most cost effective method for paint removing.
Lead laws:
If you are a contractor you must comply with the latest state and federal laws for lead paint
removal. A house owner doing his own work should also adhere to safe work practices to
eliminate lead contamination even though it may be voluntary. You have to assume any old
building containing lead paint. If you have to, confirm the lead with a lead test. Equal attention
should be paid to all other paints as well. Many unknown chemicals in petroleum oil paint and
acrylic water based paints may be highly toxic to heat.
Safety equipment:
Use gloves and goggles. Collect paint chips at the end of each day and collect in appropriate
containers. Dispose paint chips with local county hazardous waste drop of locations. Contact
your local health department for more information.
Avoid vacuum cleaners on any interior project as the exhaust from the vacuum will stir the air
spreading the very fine dust into multiple parts of the building. If a vacuum is required, always
place the canister on the outside with the hose through the window create a negative pressure in
the space. This will significantly reduce the chance of getting dust from spreading. The vacuum
should be of HEPA type. Keep in mind that the very fine lead dust is the most dangerous for
health.
Clean-up is always a necessary evil. It is extremely important not to create more dust than
necessary. Unfortunately most vacuums are not designed to collect the fine dust. It simply passes
right through the filter and out the other end. If you own a regular Shop-Vac, we do not
recommend using it for paint dust at all, because you will disburse the dust in other parts of your
home. By running the vacuum, the air will expand and transport large amounts of dust into other
adjacent spaces. If you are not going to make the investment in a new HEPA or High Efficiency
vacuum, we recommend wetting mop to keep the dust down to a minimum.
Where you place a vacuum is also important. If you are using a vacuum in the same space that
you are removing paint, you will most likely transfer substantial amount of dust into other parts
of your house no matter what vacuum you use. A HEPA or a High Efficiency vacuum will not
pass dust through its filter, but the exhaust from the motor will create air turbulence and stir dust
on the floor into the air. A simple suggestion is to create a negative air pressure in the space you
are working in.
How to create a negative air pressure: Cut a plywood sheet to fit a window in the space you are
working. Make a hole to fit the vacuum hose and the power cord. Install the plywood sheet in the
window. Place the vacuum on the outside of your house. Install the hose and the power cord
through the hole in the plywood and seal with duct tape. You may have to purchase additional
vacuum hose and a power cord. Using a remote power switch is also a good idea making it easier
to switch the vacuum on and off. Place the vacuum on the outside with the blower directed away
from the window. By having the vacuum outside, you also do not have to listen to the noise.
Why use an expensive vacuum when you place it on the outside anyway? Believe it or not, dust
flying around on the outside can still find a way inside through cracks in windows and doors. By
using a HEPA or a High efficiency vacuum, you will eliminate the chance of having fine dust
getting into your house by capturing it in the first place. Tape any cracks around doors and
windows. Try my suggestion; you will be amazed how well it works
Starting the Silent Paint Remover.
Connecting the Silent Paint Remover to a GFCI outlet is critical for safety. Using the organic
raw linseed oil on the surface and let it reconstitute the old dry paint to make it react even more
to infrared heat. The organic raw linseed oil will also bind much of the dust you may create with
the scraper. Cover the ground to ensure as much of the paint dust is collected. Start with a short
heating time to learn how long time you need to heat the old dry paint so it can be scraped off.
Never heat long enough to see the surface smoking and turning dark. You usually need shorter
heating time that you may expect. Infrared heat will heat from the inside of the wood storing
enough heat to be able to scrape the paint off. Heating time is about the same as the scraping
time. Variables as ambient temperature, thickness of the surface you are heating and the various
types of paint you are removing are all determining the heating time. Thin wood needs shorter
heating time as a solid wood post needs longer heating time. Learn how to most effectively hold
the scraper. Use sharp scrapers to be effective and have about 5-6 sharp scrapers for a 6 hour day
of scraping available. It is easier to sharpen slightly dull scrapers as it goes much faster to bring
the sharp edge. Very dull scraper blades create extra work as it slows down the paint removing
process significantly.
Sharpening scraper blades regularly. It is important to have at least 5-6 sharp scrapers handy
per 6 hours of scraping. It dull scrapers will slow you down and require significantly more work
to sharpen. Sharpen at the beginning or at the end of the day. Sharpening blades during the
course of the day will break the momentum and create inefficiency. If you are working on a large
project, dedicate one person for sharpening.
Linseed primer coat on the same day you remove the old paint. When the paint is scraped
off, the wood is very dry and will absorb organic linseed oil very well. This is a great opportunity
to get some organic boiled linseed oil into the wood. Add 15% zinc white into the linseed oil
paint if you are located in hot and humid climate.
The objective it to load the wood up with the organic boiled linseed oil. Add 15% zinc white
to the organic boiled linseed oil for extra mildew protection. It is always a good idea to wash the
surface down with the linseed oil soap EXTRA for additional protection as well. If you
experience dirt or mold buildup after some time, you need to go over the area with linseed oil
soap EXTRA as normal maintenance. Add the organic boiled linseed oil when the surface looks
dry. Normal maintenance is cleaning the surface and then wiping on the organic boiled linseed
oil for maintenance every 5-10 years.
Time and linseed oil Material study.
Here are our preliminary results on coverage rates with the Allback Linseed
Oil Paint - Pre-Treating with Allback Boiled Linseed Oil.
Four men worked for 8.5 hours and oiled and painted 965 square feet of
surface coverage - working on loose, dry, rough-sawn, poplar boards in our shop.
That works out to a production rate of 28.38 square-feet per hour, per man,
to oil and apply a first coat of linseed oil paint.
We used 12.5L (3.3 gal.) of oil and 5.5L (1.45 gal.) of paint.
That calculates to 77.2 square feet to the liter of oil (292 square feet to
the gallon) and 175 square feet to the liter of paint (666 square feet to
the gallon).
Conclusion: Very dry wood will require more organic linseed oil. As the wood surface is
saturated, the coverage increases significantly. Blotchy surfaces is a sign of very dry wood ( dry
wood is referred to as lack of natural oil in the wood and not moisture) Add extra boiled linseed
oil to even the surface. Over time, maintain the surface by wiping a coat of the organic boiled
linseed oil onto the surface bringing the color back as you maintain the wood. Always clean the
surface prior to the oiling or the paint with the linseed oil soap EXTRA.
Work and Material Description

Tool & Material list
The Silent Paint Remover
Triangular scraper
Profile scraper
Clapboard scraper
Putty Knife
Shellac flakes
Denatured Alcohol
Allback Glazing Putty
Sand paper
Cotton rags
Linseed oil soap
1. Mark each sash, glass and hardware to identify for reassembly
2. Remove all paint with the Silent Paint Remover. If old paint is very hard and does not
react to heat well, apply a thin coat of organic raw linseed oil. Allow the oil to soak into
the surface. The organic raw linseed oil will make the old dry paint react to heat better.
Lightly hand sand if necessary. Avoid powers sanding as you push any lead paint residue
into the grain of the wood at the same time you create very dangerous fine lead dust.
Avoid any chemical paint removers as you will load the wood up with various chemicals
that can cause bleeding over time as the chemicals come out of the grain during seasonal
changes. Also avoid steam for paint removing as this can cause wood to warp over time.
3. Clean all hardware by boiling in linseed oil soap and water. Scrape and brush paint off.
4. Rust proofing all metal hardware with organic boiled linseed oil. Heat the organic boiled
linseed oil and brush a thin coat onto the metal. Here, the heat from the Silent Paint
Remover can be very helpful as well.
5. Clean edges of all old glass and inspect for cracks and determine if any glass needs to be
replaced.
6. Repair any decayed wood by splicing or utilizing a Dutchman. Glue with Casein glue.
Casein glue: 10 gram hydrated lime, 50 gram cottage cheese, 20 ml water. Warm the
cottage cheese till water separates from the fat. Sift the water way. Mix well with the
lime. Add water. Let the mixture rest for about 20 minutes. Set up time 10 minutes.
Waterproof after 24 hours. Never use any epoxy repair system on windows or other wood
components for exterior as it has limited life. Here, we focus on restoration for 50 or 100
years witch none of the petroleum products is compatible with.
7. Determine if weather stripping is necessary and if the sash edges have to be slightly
shaved off to accommodate the thickness of the weather stripping.
8. Altering of the glazing groove is possible to accommodate a double pain glass but before
embarking on such a project all other alternatives should be explored. By adding a second
storm window on the inside of the window can be a great solution to altering the old sash
you are restoring.
9. Impregnate the wood surface with hot organic raw linseed oil. Heat with the Silent Paint
Remover or if very careful use a heat-gun at low setting. One good coat is usually enough
on an old window with good quality wood and maybe slightly more on a new wood
window build from kiln dried wood.
10. Mounting of hardware. Back any hardware with the linseed oil glazing putty, Cracks,
screw holes etc for extra protection. This is very important specifically in exposed areas
where lots of sun and rain beats on the surface constantly.
11. Apply a solid coat if the shellac solution on the glazing grooves as a barrier coat. Mix
shellac flakes/mineral spirits to create a thick viscosity coating. You mix this yourself by
purchasing the shellac flakes and adding just a few drops of mineral spirits. Allow the
flakes to dissolve over night if needed. The shellac should be the consistency of thin
syrup. Shellac on the glazing grooves will block the organic raw linseed oil from being
absorbed by the wood, causing the glazing putty from failing prematurely. This is one of
the most important steps in restoring an old window and to get the restoration to last.
Shellac any knots with a shellac flakes/mineral spirits as well if needed.
12. Installing the glass. Back bed the glass with a relatively thin consistency glazing putty.
Apply a good bead of putty and set the glass into the compound. You can also use a
sander with a soft cloth on the glass to gently vibrate the glass into the glazing putty.
13. Install the wood wedges between the glass edge and the glazing groove to eliminating the
window pane from sliding sideways. Cut 1” of the end of a piece of wood and split
wedges length grain to size.
14. Place the glazing pins to secure the glass in the sash. Usually you need 2 pins on each
side of the glass unless it is a small piece of glass. A larger glass may require 3 or more
pins to hold the glass in place.
15. Apply the slightly harder glazing putty on the exterior of the glass. Determine how wide
the putty seam should be including the 1/8” you will be painting onto the glass later. If do
not want to see the paint from the inside you need to make sure you measure how wide
the outside glazing should be. To make the linseed oil glazing putty harder, place the
putty on a piece of clean dry wall until you have the putty the right consistency. Never
add chalk to the putty as dry chalk can jeopardize the adhesion of the putty over time.
Dry chalk has strong surface tension and does not easily mix with organic raw linseed oil.
This also goes for dry pigment that should not be added either.
16. Add about 15 to20 % zinc white into the linseed oil paint for hot and humid climates.
Apply several thin coats carefully with a soft natural brush. The type of brush will make a
huge difference. Paint about 1/8” onto the glass for a very important seal. Linseed oil
paint adheres very well to glass. In this stage, avoid any acrylic or other petroleum paint
because it does NOT adhere to glass over time causing the window restoration to fail. If
you have to use petroleum paint for some reason, apply it after a few coats of linseed oil
paint.
17. Allow the linseed oil paint to dry over night. The linseed oil paint does not have to be
completely dry. It can still be slightly sticky but the paint should not come off. Apply 2 or
3 thin coats. Paint in 50-60 degree minimum. Linseed oil paint will dry faster in warmer
weather and with good ventilation.
18. After a few days of drying: Apply a small amount of linseed oil soap and a mist of water
onto the glass before cutting. Use a wide spackle by placing it along the glazing putty to
leave about 1/8” edge on the glass. Scrape a sharp edge with a good glass scraper. It is
very important to create the edge as it creates an excellent seal.
19. Allow the glazing putty and the linseed oil paint to cure a few days unless you work in a
cool climate or in the cooler part of the season.
20. Clean the window and the tools with the linseed oil glazing
21. Before installing the sashes in the jambs, make sure the channels are oiled and a last coat
of the linseed oil wax is applied to reduce friction.
22. Document the process with photos and fill out diagnostic sheet for future reference.
