Abstract
An omniphobic aqueous stain repellant integral grout additive contains an aminoalkyl-substituted polyorganosiloxane, preferably, a higher alkyl alkoxysilane, an organopolysiloxane T resin bearing silicon-bonded alkoxy groups, a fluoro(meth)acrylate polymer or copolymer, and preferably, a film forming (meth)acrylate polymer or copolymer latex. The omniphobic grout additive provides high stain repellancy to grout in an economic manner.
