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, cold water as specified below:
Size Water
25 lbs. (11.34 kg) 2.25-2.75 quarts [72-88 fl. oz.] (2.13-2.60 L)
10 lbs. (4.54 kg) 3.6-4.4 cups [28.8-35.2 fl.oz] (0.85-1.04 L)
7 lbs. (3.18 kg) 2.6-3.1 cups [20.2-24.6 fl. oz.] (596-729 mL)
1. Start with the low-end water range. Add water per instructions. Do not over water.
2. Mix with a drill (350 rpm max.) and mixing paddle attachment for a minimum
of 2 minutes. Drill mixing is preferred and provides optimal results – hand
mixing will yield acceptable results.
- Do not add more water until mixture has been mixed for 2 minutes. Product
consistency will loosen with mixing. Add water with care not to exceed
recommended range. Under conditions that can result a shorter pot life,
(i.e. hot weather), mix at the top end of the water range to provide more
working time.
3. Allow to slake in bucket for 3-5 minutes
4. Remix with drill and mixing paddle for a minimum of 1 minute
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.
When grouting very absorptive tiles e.g. bisque tile and/or for thin grout lines, mix
Power Grout
®
to the highest water ratio. Additionally, pre-moistening the tile edges
by spraying or wiping with a damp sponge or towel will help ensure that the grout
retains water needed to properly cure.
Clean-up
Allow grout to firm up 15-30 minutes under normal conditions before final cleanup.
Check for firmness by touching the grout with your finger. If there is transfer, wait 5
minutes and test again.
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
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.
