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 2.9 pt (1.4 L) clean water to 10 lb (4.5 kg) grout.
Mix 7.25 pt (3.43 L) clean water to 25 lb (11.34 kg) grout.
For increased stain resistance use StainBlocker for Grout Additive.
See datasheet for details.
Mixing Procedures
Dry mix bags of different batches together as they can vary slightly in
color. Mix with a trowel or low speed mixer (less than 300 rpm) for
approximately 3 minutes to achieve a smooth, lump-free consistency.
If needed add: up to 0.2pts (0.1L) of water for each 10 lb. (4.5 kg)
powder. Let the mixture stand (slake) for 5 minutes, and then remix
and use. Periodically remix grout to keep it workable but do not add
water as it can weaken the grout, cause color variation, shrinkage,
cracking and pinholes. Discard grout when it becomes too stiff to
spread.
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.
