MIXING

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.
Allow the grout to slake for 5 minutes then remix.
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.

APPLICATION

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 the cleaning water and rinse the sponge frequently.
Using clean water and a sponge will enhance color uniformity.
Remove haze from the tile surface with a soft, dry, microfiber cloth.

FINAL CLEAN-UP:
After 24 hours, the grout installation can be cleaned with clean water. Cleaning with acid is not recommended.

MOVEMENT JOINTS:
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.

MAINTENANCE:
Sealing is not required, but if used apply using a high-performance penetrating grout sealer following the 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.

CLEANING OF TOOLS
