What are the benefits of ROYAL GUARD PLASTIC CEMENT?
All Royal Guard roofing systems begin with flashings, and any other obvious trouble areas. ROYAL GUARD PLASTIC CEMENT is a full-bodied “mastic” made of the same materials as other Royal Guard products. The difference is the increased quantity of reinforcing fibers. This allows PLASTIC CEMENT to form a tight waterproof bond yet remains pliable to withstand roof expansion and contraction. Always use ROYAL GUARD PLASTIC CEMENT with GLAS-GUARD patching fabric. GLAS-GUARD is “sandwiched” between 2 layers of PLASTIC CEMENT to give greater strength to the patch (as steel is used to reinforce concrete).
