TUFCHEM Silicate Concrete – Foundation Grade (FG) is a two component inorganic acid resistant polymer concrete based upon potassium silicate chemistry. It is formulated for the casting method of placement. TUFCHEM Silicate Concrete – Foundation Grade should be installed at a minimum thickness of 1.5 in. In continuously wet environments, a chemical resistant membrane should be installed onto concrete substrates before installation of the TUFCHEM Silicate Concrete-Foundation Grade overlayment.

TUFCHEM Silicate Concrete FG Powder is supplied with factory dispersed polypropylene fibers to improve tensile properties and minimize hairline shrinkage cracks.

TUFCHEM Silicate Concrete FG is resistant to all concentrations of most acids including sulfuric, hydrochloric, nitric, chromic, acetic, and phosphoric. It is not resistant to acid fluorides or hydrofluoric acid, and should not be used in alkaline or caustic environments.
