1. An omniphobic aqueous stain repellant grout additive, comprising:
at least 5 weight percent based on the total weight of the additive, of ingredients (A) through (E):
A) 1 to 30 parts by weight of at least one aminoalkyl-functional polyorganosiloxane;
B) optionally, from up to 50 parts by weight of at least one higher alkyl alkoxysilane and/or partial hydrolysate thereof;
C) from 20 to 30 parts by weight of at least one T-functional polyorganosiloxane resin containing alkoxy groups;
D) from 20 to 70 parts by weight of at least one fluorocarbon compound containing at least one >C3 perfluorinated group;
E) optionally, up to 20 parts by weight of at least one film forming acrylic latex polymer;
where the parts by weight are for each component itself in neat form, and are relative to the total amount of components A) through E), and totaling 100 parts by weight, further comprising an effective dispersion stabilizing amount of at least one surfactant, and water.
