TEST PATCH:
Always prepare a test patch prior to full application. This will
indicate the time required for project completion and suitability of
product for the paint and substrate.
PREPARATION
Ensure that all areas not to be cleaned are suitably protected. Apply a
small test application to determine proper dwell times, effect if any,
on underlying paint/substrate, final removal and clean up methods. The
product should not be diluted and does not need any mixing before
application. Do not pre-wash the surface to be cleaned before
application of RemovALL 400
APPLICATION:
Apply a generous amount of RemovALL 400 by spray, brush, roller or a rag
to fully saturate the problem substance to be removed. A brush or roller
can be utilized for application over small areas. Larger areas will
require a small hand pump, weed sprayer or conventional spray equipment
capable of producing a fine atomized spray.
DWELL TIME:
The time required to remove or soften graffiti or overspray, depends on
the type of paints, number of layers of paint &, temperature of the
substrate.
|
Most graffiti /
over-spray will soften within 10 minutes. Do not let any application
stay on for more than 15 minutes. If the job has not been completed,
wipe off the softened graffiti / overspray with a cotton cloth and
re-apply RemovALL 400.
REMOVAL:
For small areas, removal of residue can be completed by wiping with a
dry cotton cloth, followed by a warm or soapy water rinse. For larger
surfaces, removal can be accomplished by pressure washing at
approximately 600 psi with fresh water.
OPTIMUM TEMPERATURE:
Ambient and surface temperatures should be in the range of 20° to 32° C
(65° to 95° F). The product does perform effectively at lower
temperatures (even at 32° F, 0° C), but the dwell time increases.
CAUTION:
Weak paints like interior latexes will also be
softened by RemovALL 400. To clean such surfaces, several applications
with dwell times of no more than one minute will be required. The area
should be wiped gently with a slightly dampened cotton cloth after each
application. The paint will re-harden to its original color and finish
in a few hours.
COVERAGE:
Coverage rate normally falls between 3 to 6 sq. metre per Litre. (120 to
270 sq. ft. per US gallon.)
