Ames Polyester Contouring Roof Fabric is designed for maximum saturation resulting in maximum adhesion when used in conjunction with Ames Research Labs coatings. Ames reinforcement fabric strengthens coating systems susceptible to puncture, tear, movement, and shifting. It may be cut to different widths for specialized jobs. Substantially extends the life of low-slope roof coating systems. May be used over tar, plywood, metal, and concrete.
