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 4.5 qt (4.25 L) cool, clean water to 25 lb (11.34 kg) grout.
Mix 0.9 qt (0.85 L) cool, clean water to 5 lb (2.27 kg) grout.
For 1 lb grout, see package for fill line indicator.
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.
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 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
Periodically 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.
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exteriorinstallationsandmaintain>50°F(10°C)
temperatures for at least 72 hours for proper cure.
Sealing of Grout
Use a pH-neutral, water-based, penetrating 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
Installation must comply with the requirements of all applicable local,
state and federal code jurisdictions.
