Health and Safety

Directions for Use

Joints preparation: Before beginning of grouting, always ensure that the mortar or adhesive that was used to fix the tiles has completely hardened. The joints must be thoroughly cleaned, free of dust, loose particles, and emptied to a depth of at least 2/3 of the tile thickness. Dampen the interior of the joints prior to product application.

Mixing: Depending on the desired consistency, one 10-kg bag of BATIMIX Tile Grout HP-425 must be mixed with approximately 3.5 to 4 liters of clean water for a minimum of 3 minutes. Mixing should preferably be done with a slow-speed electric mixer to avoid formation of air bubbles and to get a uniform smooth consistency. Do not mix more grout that can be used within a 20-minutes period at 23ºC and do not re-wet the mix.

Grout application: All joints must be well filled with BATIMIX Tile Grout HP-425 using a trowel rubber spatula or float, making sure that they are completely compacted with no unevenness. While still fresh, remove the excess from the surface by moving the trowel or float diagonally to joints.

Coverage: The coverage (C, kg/m2) of BATIMIX Tile Grout HP-425 varies depending on the tile thickness and size as well as on the joint width. The following formula can be used for the coverage calculation:

C = 1.6 h e (L + W)/(L x W)

L = length of tile (mm) W = width of tile (mm) h = thickness of tile (mm) e = width of joint (mm)

The actual amount of adhesive material required may vary depending on factors such as the type of tile used, the condition of the underlying surface, and the specific installation technique being used

Finishing: When BATIMIX Tile Grout HP-425 loses its plasticity, usually after 20 to 40 minutes, clean excess of grout with a wet sponge working diagonally to the joints. Rinse the sponge frequently using clean water. When applying the grout in hot, dry, or windy climates, it is advisable to moist cure the joints for at least 3 days.
