Always clean the roof surface prior to the application of primers, coatings, asphalt membranes and other types of roofing materials that require clean surfaces to ensure adhesion. Clean the ponded area as dirt collects in these areas and then rinse with clean water and let dry.


To begin application, remove all contents from the 5 gallon pail, leaving only the GreenSlope™ granules. Pour the polyurethane binder into the pail and mix thoroughly to achieve a consistent blend. Prime the area being repaired using the enclosed primer. Using a pointed trowel or screen board, evenly spread the material onto the low section of the roof to help bring the roof surface back to its original slope and achieve positive water flow to desired drainage areas. Tamp down with a trowel to close any open pores – especially around the perimeter to prevent water infiltration. Allow to dry for 24 hours prior to applying a coating over the surface to match the color of the existing roof and fully waterproof the area.
