A:  Hi Joacko, the AS- 210 is an acrylic primer vs Aquaproof that is a rubberized membrane base coat .You can apply the AS 210 as a base then Aquaproof primer as waterproof primer and lastly 100% silicone .

A:  Hi Lenny, if your rubber roof is made of EPDM then you can use the Coolguard directly. Wash and Rinse: Make sure the roof is clean. Pressure wash the roof with a mild detergent and rinse thoroughly. Remove all dirt, grease and loose particles such as gravel, old coating, etc. Remove any mildew or fungus with a bleach solution of 2 parts water and 1 part bleach. If needed use a scrub brush. Apply with a heavy nap roller or airless sprayer in two (2) coats; allow 24 hours dry time between each coat. Apply only at temperatures above 50oF. Do not apply if temperature is expected to drop below 50oF before the coating has completely dried. Do not apply if roof surface is above 100 degrees F. If roof is too hot, spray with water, allow to dry and recoat before surface temperature rises above 100 degrees F. Each coat should be applied in a perpendicular direction from previous coat. Allow 24 hours dry between coats.. Do not apply if rain is forecast within 24 hours. Do not apply after 4 PM. NEVER THIN OR DILUTE FROM FULL STRENGTH. If your rubber is TPO then we suggest to prime before with Aqua Proof Primer and then the Coolguard.
