5. INSTALLATION INSTRUCTIONS
Mixing—With Water
For best results pour liquid in a bucket and then add powder. In a clean mixing
container, add AccuColor
®
grout to clean, cool water as specified below:

-3 cups [22-24 fl. oz.] (600-700 mL)
1 lbs. (0.454 kg)
2.25-2.5 fl. oz. (66-74 mL)
Mix well. Avoid breathing dust and contact with eyes and skin. Allow mixture to
“slake” (sit in the container) for 10 minutes, then remix before using. Slaking
allows the water, Portland cement and other ingredients to react properly. The
working time (pot life) when mixed this way is approximately 1 to 2 hours.
Note: If less than a full container of AccuColor
®
grout is going to be mixed at one
time, or multiple bags are used from different lot numbers, mix the dry grout
prior to taking out desired amount. (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 liquid to
grout proportions when using multiple containers for the same job.
Mixing—With Latex Additive
For exterior or other applications subjected to freeze/thaw conditions or
other ANSI A118.7 applications, use TEC
®
Acrylic Grout Additive in place of
water. In addition, H.B. Fuller Construction Products Inc. (“HBF-CP”) recommends
use of liquid latex additive in any installation where increased flexibility is desired
or high water resistance is required. Note: Liquid latex additives should not be
used when grouting marble or natural stone.
Application
Fully pack the joints between the tiles by spreading AccuColor
®
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,
1
⁄
2
to 1 hour for grout mixed with water
and 30 minutes for liquid latex-modified grout. Wet a grout sponge in a pail
containing cool, clean water and wring out all excess liquid. Move the dampened
sponge across the tiles diagonally to smooth the grout down to the proper height
in the joint. Continue this procedure, repeatedly rinsing the sponge in clean water
and wringing out excess liquid. Do not allow excess cleaning water to remain
on the surface of the grout joint. Allow the grout to dry an additional hour before
removing any remaining grout residue with a dampened terrycloth towel.
For removing any remaining grout residue, use a grout haze remover.
Protection/Damp Curing
Protect the finished installation from traffic or impact for at least 24 hours; from
water immersion or freezing for at least 72 hours. Sealing grout is recommended.
HBF-CP recommends the use of TEC
®
brand premium sealers for protecting grout,
tile and stone from staining. Consult sealer directions for proper application.
Damp curing is highly recommended in cementitious grout installations to
promote complete cure. Damp curing is best accomplished by covering the tile
and grout with a single layer of 40# natural kraft paper for 72 hours. Periodically,
mist the kraft paper with water to maintain a moist atmosphere over the tiled
surface. Do not use newspaper, plywood overlay or polyethylene film for curing.
