Stripping Paint
IMPOrTaNT: read the general operating and safety information sections of this owner's
manual before using the heat gun.
The heat gun heats up the surface and causes the paint to soften, at which time it can be
scraped off easily without damaging the surface. Some paints may soften even though they do
not blister; some may become rubbery, and some may require higher heat.
When working with several layers of paint, it speeds up the scraping process to heat the surface
thoroughly, all the way to the wood. Then all the layers can be scraped at one time.
A soft wire brush may be the best tool to use for very intricate surfaces. Mineral paints and
finishes, such as cement paint and porcelain, do not soften with heat, so using a heating tool will
not work for paint removal.
The best method of paint removal
Move the gun slowly and steadily forward at an angle to
the surface, pointing the nozzle in the direction of motion.
This allows you to scrape safely outside the hot air stream
and keeps the scraper and the scraped surface cooler.
A. Warm air preheats the surface.
B. Paint is softened by hot air.
A + B. Deep penetration of heat over total area.
C. Paint can be easily scraped off as soon as it is
softened and the gun is moved forward.
D. Stripped surface allowed to cool.
Note: do not use the heat gun on surfaces that can be damaged by heat, such as vinyl-
coated paneling, siding or window frames.
When removing paint from window frames, the heat gun will soften the putty.
Be careful not to gouge the putty with the scraper. The putty will firm up after it
cools.
do not use the heat gun on insulating laminated window glass such as
Thermopane. The glass edge expansion may break the edge seal.
When scraping fascia, do not overheat the edges of the asphalt shingles
protruding over the edge of the sheathing. Too much heat will melt the asphalt.
IMPOrTaNT: The removal of paint by heat gun is safe if the above guidelines are used,
but always keep either a container of water or an aBC fire extinguisher (suitable against
Class a, B and C type fires) within reach.
