A special blend of adhesive asphalts, fibers, special resins, and other ingredients that assure its rapid fusion to the base surface. Indended primarily as a blind nailing cement for use with roll roofing. It creates a tight bond and prevents buckling and curling of edges. Roof adhesive is also suitable for application to older roofs to seal cracks and pinholes.

Adhesive for Rolled Roofing

Clean Surface - Clean surface with brush or broom, removing all loose sediment and dirt. Nail down any loose parts. Repair any leaking or weak areas with SealBest Roof Cement and SealBest Reinforcing Fabric repair material.

Applying Roof Coating - Stir pail thoroughly. Do not dilute. Apply with a roofer's brush or masonry trowel in a uniform consistency. Apply a sufficient amount of adhesive to cover the entire underside of the membrane and to allow a 1/8" - 1/4" bead of adhesive to form along the lap seam when membrane is pressed into place. Broom or walk the overlying sheet firmly into the cement and smooth it out to prevent buckles or blisters.
