Cop-R-Tite Mastic was developed to ensure the proper sealing characteristics of copper laminated flashings. Cop-R-Tite Mastic is manufactured to a trowel grade consistency that will provide a durable coating with excellent adhesion qualities. At last there is no need to worry about compatibility of mastics to flashing.
Stocked in quart caulk tubes and 5 gallon pails.
