ABSTRACT:
A tile grout composition and method of using the tile grout composition to grout set tiles are provided. The tile grout composition is a water-based epoxy grout composition which has excellent stain and chemical resistant properties and is workable and easy to clean up after grouting the tiles. The grout composition employs a water dispersible epoxy polymer and a water compatible polyamine epoxy resin adduct as the curing agent in combination with a water repellent component. For colored grouts, a color coated filler such as sand is employed to obtain the enhanced tile grout properties. Luminescent and fluorescent additives and sparkle additives may be used in the grout to provide special visual effects in the light or dark.
