5. INSTALLATION INSTRUCTIONS
Mixing
For best results pour water in a bucket and then add powder. In a clean mixing
container, add Power Grout
®
to clean, cool water as specified below:

cups [18-21 fl. oz.] (532-621 mL)
5 lbs. (2.27 kg)
13-14 fl. oz. (0.34-0.38 L)
Mix for 2 minutes. Avoid breathing dust and contact with eyes and skin. Allow
mixture to “slake” (sit in the container) for 3-5 minutes, then remix before using.
Slaking allows the water, cement and other ingredients to react properly.
Note: HBF-CP recommends that a full container of Power Grout
®
be mixed and
used at one time. However, if less than a full container of grout or multiple
containers from different lot numbers are used, pre-mix the entire contents
of the container(s) prior to mixing with water. (The fine pigment particles
may settle during shipment and color variance can occur in the finished joint
unless you first dry blend in this fashion.)
To ensure color consistency across the installation, use the same water to
grout proportions when using multiple containers for the same job.
Application
Fully pack the joints between the tiles by spreading Power Grout
®
with a clean,
hard rubber float. Work only a small area at one time [5-10 sq. ft. (0.5-1 m
2
)].
Apply in a diagonal direction across the joint lines to prevent the grout from
being dragged out of the joints. Go over each area several times from all
directions to make sure that the grout is fully packed in. Remove any excess
grout from the surface of the tile by holding the float at a 90° angle to the
surface and moving it diagonally across the joints. Repeat the entire process
until all joints are grouted.
Clean-up
Allow the grout to firm up in the joints, 20 to 30 minutes under normal conditions.
Check for firmness by touching the grout with your finger. If there is transfer, wait
15 minutes and test again. When there’s no transfer it is time to begin clean-up.
Wet a grout sponge in a pail containing cool, fresh water and wring out. Loosen
the grout on the tile surface by moving the sponge in a circular motion across the
tiles. Then use the sponge to smooth the joints. Completely rinse and wring out
the sponge. Wipe diagonally across the tiles to remove grout residue. Use each
side of the sponge once, then rinse, completely wring out and repeat. Change the
water frequently.
Allow the grout to dry 30 to 60 minutes and remove all remaining grout residue
from the tiles with a damp sponge or terrycloth towel.
Protection/Damp Curing
Protect the finished installation from foot traffic or impact for at least 4 hours.
Wait 24 hours before mopping, routine cleaning or shower use. Do not expose to
stains, complete water immersion or freezing for 7 days.
No need to seal grout. If tile or stone is to be sealed after grout is installed, use a
compatible solvent based sealer. Test a small area of the tile/stone and grout to
ensure you achieve the desired results.
If a water-based sealer is required, consult Technical Support for a list of approved
sealers. Allow grout to cure for 72 hours before sealing.
