Installation Guide

DS121 9/04R
SURFACE PREPARATION
Tile must be firmly attached to a sound substrate and setting
material must be cured a minimum of 24 - 48 hours before
grouting
. Remove all spacers. Grout joints should be uniform
in depth and width and free of all loose debris, contaminants
and excess mortar. Pre-seal tile or stone that can be subject to
staining with TileLab SurfaceGard Penetrating Sealer.
MIXING
Start with 3 pints (1.4 L) of cool, clean water. Mix in 10 lbs.
(4.54 kg) of grout with a margin trowel or low speed mixer
(less than 300 RPMs) to a smooth, paste-like, non-pourable
consistency. If needed, up to one pint (473 ml) of additional
water may be added to adjust consistency. Do not use
additives. Let stand 10 minutes, re-mix before use. Periodically
re-stir; do not add additional water as this weakens the
material. Discard grout when too stiff to work, about 2 hours.
APPLICATION
Installation to 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, force grout diagonally into joints ensuring joints
are completely filled. Remove excess grout using edge of float
held at a 90° angle. Cleanup can begin when grout can be only
slightly indented when pushed hard with your fingernail or
about 10 – 20 minutes depending on type of tile and ambient
temperature. Use as little water as possible for grout cleanup.
Excess water will weaken the joint, cause variation in color and
may cause shrinkage, cracks or pinholes. Smooth and level
joints and remove excess grout from tile with a damp (not wet)
small pore (hydrophilic) grout sponge using a circular motion.
Change water and rinse sponge frequently
. Using clean water
and sponge will enhance color uniformity. Wait 2 hours before
removing haze from tile surface with a soft, dry cloth.
CURING
P
eriodically mist the installation with clean, cool water for
3 days. If grouting dense (low absorptive), vitreous or semi-
vitreous tile, curing time will be extended. We recommend
using P
olyblend
®
Grout.
PRODUCT DESCRIPTION
White Dry Tile Grout is non-sanded and formulated for grouting
porous floor and wall tiles with joints up to 1/8" (3 mm) wide.
Ideal for use with glazed tile and polished marble that can be
scratched by sanded grout. It can be used for interior and
exterior applications. Meets ANSI A118.6 specifications.
USES
n
For grouting soft glazed tile, marble or other polished stone
that could be scratched by sanded grouts.
n
For grout joints up to 1/8" (3 mm).
n
Use on floors, countertops, walls, ceilings, showers, fountains
and pools.
n
For interior or exterior installations.
LIMITATIONS
n
Portland cement grout should not be installed when ambient
temperature is below 50° F (10° C) or for exterior applica-
tions if rain is expected within 24 hours.
n
For industrial and commercial installations where chemical
resistance is required, use 100% Solids Epoxy Grout in
accordance with ANSI A118.3.
n
Generally white grout is best suited for grouting white or
light colored marble or granite. Follow tile manufacturer’s
recommendations. Test a small area prior to use.
Certain tile with high absorption, surface porosity or rough,
textured surfaces and certain types of porcelain may require
sealing prior to grouting to prevent staining. Use TileLab
®
SurfaceGard
®
Penetrating Sealer as a grout release to
prevent grout staining when required.
n
Efflorescence, a crystalline deposit that sometimes appears
on cement grout as a whitish powder or crust, can occur
with any Portland cement based product. If it occurs,
remove with TileL
ab Sulfamic Acid Cleaner or Grout Haze
Remover according to directions. Some natural stones
are sensitive to acids. Test cleaners in an inconspicuous
area before use. If the stone is sensitive, use TileL
ab
Heavy-Duty Cleaner & Stripper.
