(1) General preparations. The following actions will
prepare the equipment for cleaning and stripping:
preferably in shaded area, attach a static
For best results, ambient temperature
should be approximately between 50 and
100°F (10 and 37°C). Do not attempt to
accomplish paint removal in rain, or on
surfaces which are not dry.
When painted surface is exceptionally
dirty or coated with fuel, oil, grease, mud
before applying remover.
After equipment has been cleaned, allow
sufficient time for surfaces and crevices
to dry thoroughly. Water remaining on
detrimental effect on paint removers.
(2) Chemical Removal from Metals. The use of
MIL-R-81924 paint remover is described in the following
Prolonged breathing of remover fumes
must be avoided as serious health
problems may result. Use only in well
Removers must be well mixed before use
as they tend to segregate on standing.
Do this by agitating with a wooden paddle
if mechanical mixers are not available.
Rolling a drum will not mix its content
very effectively. At temperatures below
600F, the removal power of removers will
be noticeably slower than at higher
(3) Applying removers. Beginning at the highest
point of any vertical or sloping surface, apply a coat of
remover with a suitable brush. Barrel pump and spray
gun may be used for application of removers. In no
case should the spray be highly atomized. Agitate with
a stiff fiber brush, if necessary, to loosen paint. A wet
film of remover should be maintained on the surface
being stripped to obtain efficient removal. This may
require additional application of the remover. Areas
should be treated progressively, kept wet, and allowed
sufficient time for the stripping action. Best results are
obtained by applying removers in shaded areas since
sunlight dries the remover quickly.
(4) Painted surfaces. Enamel surfaces should
wrinkle within 5 to 15 minutes after application. Most
surfaces with lacquer or polyurethane paint will not
wrinkle but will merely be softened by the remover;
allow remover to remain 8 to 20 minutes, keeping a wet
surface by applying another coat of remover if
Zinc chromate primed surface, where
topcoat material has not been applied,
should be washed down as soon as
possible after initial loosening of primer.
If the surface becomes dry, another
application of remover is required since
redeposited on the surface.
(5) Cleanup of stripped surfaces. Flush the stripped
surfaces, using warm water at 150 to 250 psi maximum.
If high pressure warm water is not available, cold water
at usual hydrant pressure may be used. This will require
a longer time to accomplish the washing.
