Tile grouts are generally of polymer modified cementitious or epoxy resin based. It should be flexible in nature; should accommodate movements and also should not shrink like white cement. It should have a good bond with all types of tiles, thus making joints impermeable to water. In situations where non-toxic, chemical resistant
properties for tile joint filler are required especially in food and pharma industry, epoxy resin based is the ideal solution.
1. Grouting should not begin until the tile
setting material is properly cured (a minimum
of 24 hours).
2. Wipe the tile surface with a damp cloth
before grouting.
3. Using a Float, trowel the mixed grout over the
surface and into the grout joint, careful to assure all
joints are filled fully. Hold the float at a 45O angle to
the surface of the tile.
4. As soon as possible, remove excess grout from the
tile surface with float held at a 90O angle and moving
diagonally across the joints. Strike the joint with the
blunt end of a tool-compacting the surface but not
