Description
Siena Mastic 625
Siena Mastic 625 is a non-slip high performance, smooth spreading mastic formulated for interior installation of all types of wall and floor tile on vertical or horizontal surfaces. It is non-flammable, freeze-thaw stable to 10º F, and exceeds ANSI-A-136.1 Type 1 specification on organic adhesive for the installation of most tile and stone. Organic mastics are not recommended for exterior use.
Siena Mastic 625 can be used over APA grade underlayment plywood, association grade particleboard, cork underlayments, existing well-bonded vinyl, tile and sheet flooring, terrazzo, radiant heated subfloors where surface temperatures do not exceed 85°F, concrete, and TCNA approved vertical surfaces. Install above, on, or below grade, in the absence of excessive moisture and alkali. The pH levels of concrete should be greater than 5 and less than 9.
