5 Instructions
General Surface Prep
Tile or stone must be firmly bonded to a sound substrate, and setting
material must be cured a minimum 24-48 hours before cement grout
is applied, unless rapid-setting mortars are used. See the
corresponding data for the bonding mortars used in your application.
Remove spacers and ensure that the grout joints are uniform in depth
and width and free of loose debris, contaminants and excess mortar.
Use TileLab®SurfaceGard®Sealer to seal tile or stone subject to
staining or when using a grout that contrasts with the color of the tile.
Mixing Ratios
Mix 4-5 pt (1.89-2.36 L) clean water to 17 lb (7.71 kg) box. Do not use
additives.
Mixing Procedures
Mix with a trowel or low speed mixer (less than 300 rpm) to achieve a
smooth, lump-free consistency. Let the mixture stand (slake) for 10
minutes, and then remix and use. Periodically remix to keep the
mixture workable, but do not add water, which can weaken the joint,
cause color variation and possible cause shrinkage, cracks and
pinholes. Discard grout when it becomes too stiff to work.
Application of Product
Installation must conform to ANSI A108.10. Lightly dampen absorptive,
highly porous tile with clean, cool water, but leave no standing water
inthejoints.Holdingarubbergroutfloatata45°angle,completelyfill

30 minutes of the grout firming and use as little water as possible for
grout clean-up. Using a damp, small pore grout sponge in a circular
motion, smooth and level joints and remove excess grout. Change the
water and rinse the sponge frequently. Haze can be removed after 3
hours with cheesecloth or wrung-out sponge. If haze persists, the
installation can be washed after three days with Aqua Mix
NanoScrub or after seven days with AquaMix®SulfamicAcid
Crystals or TileLab®SulfamicAcidCleaner. Perform a test in an
inconspicuous area prior to complete application.
Curing of Product
Curing time is affected by ambient and surface temperatures and
humidity. Use the following as a guideline. For exterior applications, it
is recommended that the installation is periodically misted with clean,
cool water for 3 days.
Sealing of Grout
Use a pH neutral sealer such as AquaMix Sealer's Choice
Gold or TileLab Surface Guard.
Cleaning of equipment
Clean tools and hands with water before the material dries.
Health Precautions
This product contains Portland cement. 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. Use
with adequate ventilation; do not breathe dust and wear a NIOSH
approved respirator. If ingested, do not induce vomiting; call a
physician immediately.
Conformance to Building Codes
