Preparation
Before applying ProGRP Topcoat it will be necessary to lightly sand the whole of the roof surface, corners and details. Smooth, unblemished surfaces will produce a high-quality finish when top coated. After the roof has been sanded an Acetone wipe will aid adhesion of the final topcoat. using a sanding pad or sandpaper lightly sand the corners taking care not to create any holes.
Top coating
Calculate the amount of topcoat required, measure out into a bucket and add catalyst to each batch of topcoat as you need it. Stir well for at least 1 minute. Apply to the roof surface starting at the furthest point from the exit point on the roof and using the relevant sized soft application roller. The topcoat applied should allow the fibre pattern of the laminate to still be visible after application.
Non-Slip Finish
If a non-slip finish is required, grit or slate chippings can be sprinkled onto the topcoat, this should be added by hand or a dispenser as the roof is top coated. For a neat finish use masking tape or battens to define the edges of the aggregated areas.
