7165 Tru-Mastic Seam Sealer Brush Grade is a soft, brushable elastomeric mastic for sealing roof seams, vent stacks, etc. on galvanized or painted metal.

Has the unique ability to develop strong tensile strength quickly, plus the elastomeric properties withstand flexing over a long period of time when used as a preparation material over seams and fasteners on metal roofs.

Excellent adhesion and flexibility.

7165 will not stain, bleed, or crack.

7165 is a thixotropic (butter-like) consistency for ease of application. It can be caulked, squirt bottled or gun applied over seams and fasteners for durable sealing. ‍

Applicable Roof Types

Metal Roof

With prolonged exposure to sun and weather, metal roofing systems inevitably deteriorate overtime — developing leaks, rust and corrosion. Years of heat-related expansion and contraction also loosen seams and fasteners, potentially damaging the roof and building structure. Whether you have a new metal roof or one in need of reinforcements, you can protect it and extend its lifespan with TRUCO Coatings easy-to-apply SEBS and Silicone roof coatings.
