Extend the life of your rubber roof! Two-part, commercial grade system combines a primer/cleaner necessary for proper roof preparation with an acrylic coating to provide an excellent protective barrier for extending the life of the EPDM rubber membrane. This two-part system (primer/cleaner & acrylic coating) saves over 25% in labor compared to similar systems. Quick drying time. Endorsed by Carlisle Syntec Systems.---Breakthrough product dramatically increases the bond of Sure-Seal® White Acrylic Coating to new or weathered rubber roof surfaces. This low viscosity liquid chemically alters the rubber surface to which it is applied, creating a "lock and key" effect with the acrylic coating.
