Some types of glazed ceramic tile, marble and stone can be scratched, stained or damaged when grouted with
pigmented or sanded grouts. Generally white grout is best suited for grouting white or light colored marble or
granite. Follow tile manufacturer’s recommendations. Test a small area prior to use. Certain tile with high
absorption, surface porosity or rough textured surfaces and certain types of porcelain may require sealing prior to
grouting to prevent staining.
Surface Preparation:
Tile must be firmly attached to a sound substrate and setting material must be cured for a minimum of 24-48
hours before grouting. Remove all spacers. Grout joints should be uniform in depth and width and free of all loose
debris, contaminants and excess mortar or adhesive.
Application:
New installation:
Before grouting, soak the grout sponge in a pail of clean cool water and thoroughly wring out. Next, use the
dampened sponge and lightly wipe the tile surface in an area no larger than 5-10 sq.ft. A slightly wet tile surface
allows the grout to glide easily over the tile and into the grout joint while providing for easier cleanup. While tile is
still damp, dispense a liberal amount of grout onto the tile surface. Using the grout float, press the grout into the
grout joints over the dampened area apply grout on no more than 5-10 sq. ft. at a time to allow for prompt
cleaning; delayed cleaning may cause some cracking. Next, place the grout float on edge at a 45° angle and rake
the float diagonally across the tile surface while exerting a downward pressure. This will force the grout evenly
into the grout joints. Immediately remove all excess grout from the tile surface by holding the grout flat at a 90 °
angle to the tile and drawing it diagonally across the tile. Finally, clean by soaking grout sponge in clean cool
water. Wring out excess water completely. Use dampened sponge in a circular motion to smooth grout joints and
clean off any remaining excess grout. Continued rinsing of sponge in clean, cool water will aid in cleanup. Avoid
excess water in grout joints. For final cleaning/haze removal, allow grout to cure for 24 hours. Use a dampened
sponge, then soft cloth to polish off residue.
Repair existing grout:
Remove existing old grout with a grout saw 1/8” below the surface of existing tile, Sweep or vacuum dust and
debris from surface of tile and grout joints. Shaw Array-Grout can be applied directly over old grout. Apply
enough to totally cover the old grout. Follow directions for new installation as shown above.
Cleanup:
Clean tools and hands with cold water before material dries.
Care and Maintenance:
Mold and Mildew can grow on dirt, food, and soap scum that can accumulate on the grout surface. Routine
cleaning will limit mold and mildew growth.
Safety:
Avoid eye contact or prolonged contact with skin. Wash thoroughly after handling. If eye contact occurs, flush
with water for 15 minutes and consult a physician.
