TekFlex® Black AP is a cement-based spray material designed with superb flexibility, high tensile strength and excellent adhesive qualities.
The product enhances the structural integrity of the rock and forms an impervious barrier, which eliminates the degrading effects of weathering. Material coverage at a thickness of 1/6” for a 1 bag / 2-1/2 pail batch varies from 70 to 140 square feet, depending on the roughness of the rock surface.
