Applied Product Ready for Use

Do not disturb grout or walk over installed tiles for at least 24 hours after setting. Do not allow heavy traffic over installed tiles for at least 72 hours after setting. For residential showers and tub surrounds, restrict use for 24 to 48 hours after grouting. For steam showers, restrict use for 14 days after grouting. Like other Portland cement products, SikaTile®-800 Unsanded Grout will reach full curing in 28 days.


To minimize color variation when using multiple containers of the same grout, dry blend the powders prior to the addition of water. Add approximately 2.75 – 2.85 pints (1.30 – 1.35 L) of cool potable water for every 10 lbs. (4.53 kg.) of SikaTile®-800 Unsanded Grout in a clean mixing container. Add the grout to the water slowly; blend by hand or power mixer at low speed (less than 200 RPM). The ideal grout looks stiff but has a creamy consistency. Periodic mixing during use keeps the grout workable, but do not add additional water or additives. When the grout becomes dry and difficult to work, discard and make a new batch. For best results on multiple mixes, have the same person mix the grout to ensure the repetition of the mixing technique.


Read all installation instructions before installation and reference ANSI A108.10-1999. Slightly moisten the tile surface with a damp grout sponge before application. Holding a rubber grout float at a 45° angle, force grout diagonally into joints ensuring joints are completely filled. Remove excess grout using the edge of the float held at a 90° angle. Cleanup can begin as soon as the grout becomes firm enough to only be slightly indented when pushed. Use as little water as possible for grout cleanup. Excess water will cause variation in color and may cause shrinkage, cracks or pinholes. Smooth and level joints and, in a circular motion, remove excess grout from tile with a moist small-pore grout sponge. It is best to change cleaning water and rinse sponge frequently. Using clean water and sponge will enhance color uniformity. Remove haze from tile surface with a soft, dry, microfiber cloth.


After 24 hours, the grout installation can be cleaned with clean water. Cleaning with acid is not recommended.


All expansion, control, construction, cold, saw-cut, isolation, contraction, and seismic joints in the structure should continue through the tilework, including such joints at vertical surfaces, as specified per TCNA Method EJ171 or TTMAC Specification Guide 09 30 00, Detail 301MJ.


Sealing is not required, but if used apply using a high-performance penetrating grout sealer following manufacturer’s directions. Grout must be fully cured for 21 days before regular cleaning. To maintain a clean tile surface, use a neutral-pH cleaner for maintaining the floor, followed by a clean-water rinse. Do not use harsh chemical cleaners to maintain the tile surface. Before proceeding with cleaning, consult the cleaner’s manufacturer for compatibility, use and application instructions. Remove or rinse fatty acid residue from the grout surface to avoid potential grout deterioration caused by prolonged exposure.
