TEST PATCH:
Always prepare a test patch before full application. This will suggest
the time needed for project completion and suitability of product for
the paint and substrate.
EQUIPMENT AND TOOLS:
This product is engineered for spray application. Airless sprayers or
HVLP spray equipment are recommended. Even the smallest airless sprayer
can spray this product. Equip the sprayer with a tip size of 0.019
inches or larger. (Example: a 519 or 425 tip). Other equipment: brushes,
rollers, scraper, masking tape / polyethylene sheet, pressure washer,
electric drill with mixer, empty pails for clean-up, running water,
rags.
PREPARATION:
(a) MASKING: Cover / protect areas where the paint is to be left
on. This includes adjoining surfaces where over spray may travel.
Polyethylene sheets make an effective barrier. If using masking tape,
apply two layers of tape and remove the top layer immediately after
application as the remover may soak through the tape, damaging paint
under it. Plants should be covered or washed thoroughly with water
before and during application.
(b) MIXING: If, on visual examination, water appears to have
separated out of the product, thoroughly mix the remover with a high
speed drill mixer till it becomes homogenous once again. (Usually within
20 minutes)
(c) EQUIPMENT: Remove all filters from the pump, sprayer and gun.
Prime the pump and run remover through the hose and gun till all
previous water / solvent / paint residue has been cleaned out.
APPLICATION PROCEDURE:
Apply a thick, even layer of remover onto the coating being removed. An
airless spray machine is the most effective means for application.
Always start the sprayer pump at the lowest pressure setting and slowly
build up the pressure till an adequate fan pattern has been generated.
High pressure is neither wanted nor desired. High pressure and narrow
tip sizes will break the remover's emulsion and will destroy its
effectiveness.
When trying to build up films thicker than 30 mils (600 microns), or
when trying to apply the remover on a glossy or greasy vertical surface,
it is advisable to build the remover film in two separate applications.
First apply a light coat of roughly 10 mils (250 microns), allow it to
dwell for about 30 minutes and then build the rest of the remover film
thickness in a second application. Once applied, leave the remover
alone, as agitation slows down penetration.

Brushing and rolling
should be avoided because these methods produce a lower film build and
inconsistent thickness of remover. If a brush must be used, then use the
brush like a spade (shovel), to deposit the remover onto the paint
surface. Do not try to spread the remover with the brush.
COVERAGE:
The product is engineered for thick film build up on vertical and
overhead surfaces. The desirable wet film thickness of remover is
roughly one and a half times the dry film thickness of the paint.
Minimum wet film thickness is 15 mils (300 microns). Coverage is about
40 to 90 sq. ft. / US gal (1 to 2.2 sq. m / L)
DWELL TIME:
The time needed for penetration varies according to the type of paint,
the thickness of the paint, and the temperature. Most paint systems
require between 1 to 6 hours. Leave the remover overnight for best
results.
RE-APPLICATION:
When there are multiple layers of paint, it is likely that there is poor
inter-coat adhesion between some layers. Premature lifting may occur at
this interface. If this happens, remove the lifted layers and re-apply
the remover. Do not allow the remover to dry out. The remover is
designed to remain wet and effective over extended periods of time (up
to 48 hours), but excessive sunshine, windy conditions or insufficient
remover thickness can cause early drying. If the remover starts to dry,
reapply a light coating and allow extra time for completion.
REMOVAL AND CLEANUP:
Removal of lifted paint can be completed by scraper, squeegee, wet/dry
vacuum suction system or by high pressure (2,500 - 3,500 psi) water
wash. The stripped surface must be rinsed with water to remove all
chemical residues before re-painting. Collect lifted paint and dispose
of according to local government regulations. Do not collect and/or
store removed paint and remover waste residue in metal containers. Clean
spray equipment by running water through the equipment soon after the
spraying has been finished.
OPTIMUM TEMPERATURE:
Surface temperatures should be 65° to 95° F (20° to 32° C). The product
does perform effectively at lower temperatures (even at 32° F, 0° C),
but the dwell time increases.
SAFETY PRECAUTIONS:
Always follow proper safety procedures while handling the product. Refer
to the Material Safety Data Sheet for important health and safety
information before use.
