5 Instructions
General Surface Prep
USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when
handling product.
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 sheet 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 or Aqua Mix® Grout Release to seal
tile or stone subject to staining or when using a grout that contrasts
with the color of the tile.
Mixing Ratios
Mix 2 qt (1.89 L) clean water to 25 lb (11.34 kg) grout.
Mix 1 pt (.473 L) clean water to 7 lb (3.17 kg) grout.
Mixing Procedures
When installing more than 1 container of grout at a time, blend dry
powders prior to mixing with water. Mix with a trowel or low speed
mixer (less than 300 rpm) to achieve a smooth, lump-free consistency
(approximately 3 minutes). Let the mixture stand (slake) for 5 minutes,
and then remix and use. Periodically remix to keep the mixture
workable, but do not add water, which can weaken the grout, 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 the joints. Holding the edge of the float at a 90° angle,
remove excess grout. At 70° F, do not spread more grout than can be
cleaned within 30 minutes of the grout firming and use as little water
as possible for grout clean-up (higher temperatures may shorten this
time frame). 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 ten days with Aqua Mix® Sulfamic Acid
Crystals, TileLab® Sulfamic Acid Cleaner or Aqua Mix® Cement Grout
Haze Remover. Perform a test in an inconspicuous area prior to
complete application. Movement joints are required for perimeters and
other changes of plane in all installations. See TCNA Detail EJ171 for
recommendations.
Curing of Product
Curing time is affected by ambient and surface temperatures and
humidity. For exterior applications, it is recommended that the
installation is misted periodically with clean, cool water for 3 days.
Exterior applications must be protected from rain, snow and other wet
conditions for at least 7 days with temperature above 50° F (10° C). If
inclement weather is expected, protect the work area with tenting at
least 1 foot (30 cm) above the finished surface to allow air flow.
Enclose and protect installations and maintain >50° F (10° C)
temperatures for at least 72 hours for proper cure.
