Good preparation is key to a professional looking, long lasting finish. Remove any loose or peeling paint and obvious solid soil or dusty agglomerates.
Wet Test a small area prior to application to determine the thickness (generally 3mm) of QSTRIP required and note the time (minimum 40 minutes) needed to allow it to work
Apply using a brush, roller or applicator pad, and leave QSTRIP for a minimum of 40 minutes to soften and dissolve the film. Thicker coatings may take a few hours. It is advisable to check a small area with a palette knife. If it removes easily proceed with the entire area.
On stubborn coatings use a stiff broom or brush, (pay close attention to cracks and grooves), then remove by scraping, scrubbing or power wash.
Generally, two applications will work, however sometimes a third application may be required. Leave to dry and examine. Repeat process in any areas that have not been removed until the entire area is acceptable.
