Abstract
A premixed composition is formed from modified polyacrylate polymer, silicone emulsion, one or more amine compounds, and silane, that cures rapidly to form a composition that can be used as a grout or coating. The premixed composition includes a latex resin including an acrylic-based polymer, a silicone emulsion, one or more amine compounds, and a silane, and optionally various fillers, pigments, and adjuvants. These components in the proper proportions form a stable viscous suspension that can be floated into tile joints, and cleaned from an adjacent tile surface. The composition rapidly cures to form a hard mass that is resistant to abrasion, in both dry and wet conditions, is color consistent, and is resistant to staining.
