Follow our Step By Step instructions
to learn how to clean the gelcoat
Step 1
Hempel's Gelcoat Cleaning Powder is particularly suited for cleaning of large areas, such as skid-proof decks, where there is a build-up of contaminants. Wet the gelcoat surface with clean, fresh water.
Step 2
Mix the Hempel's Gelcoat Cleaning Powder with fresh water in order to obtain a paste and apply the paste evenly onto the surface. After approximately 10-20 minutes, while the paste is still moist, clean the surface with a soft brush.
Step 3
Rinse thoroughly with fresh water. Depending on application conditions, the treatment may need to be repeated.
