442 Tuff Flex Additive


442 Tuff Flex is a compounded and stabilized latex emulsion for use with 700 Premium Set (or a non-modified thin set mortar).

700 Premium Set (or a non-modified thin set) with the addition of 442 Tuff Flex is notched troweled to form a thin mortar bed for the installation of porcelain, granite, quarry tile, glass mosaic, dimensional stone and other hard to bond tiles. When cured, these mortars display excellent physical properties in adhesion, resiliency, water and weather resistance, and exceed ANSI A-118.4 requirements.
