An omniphobic aqueous stain repellant integral grout additive contains an aminoalkyl-substituted polyorganosiioxane, preferably, a higher alkyl allcoxysilane, an organopolysiloxane T resin bearing silicon-bonded alkoxy groups, a fiuoro(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. |
