Installation Instructions

the grout joint.
4. Work grout back and forth at a 45° angle to the face of the tile. Firmly press grout into the grout joints to ensure they are
fully packed. Failure to fully pack joints may compromise structural integrity.
5. DO NOT grout the expansion gap around the perimeter of the room, toilet ange and permanently installed cabinetry,
etc. Caulk should be used in the expansion gap in installations exposed to moisture, such as in a bathroom. Other areas
are covered with mouldings.
6. STEP 2: Remove all excess grout by holding rubber oat at a 90° angle, working diagonally across the face of the tile
to prevent grout removal from joints.
7. Clean-up as you nish each 10 sq. ft. (See Clean Up)
WORKING AREA
Working time of grout is approximately 2-3 hours at 70° F. Warm and dry conditions reduce working time, while cool
and humid conditions extend it. Covering the grout pail with the lid when not in use will extend working time.
CLEAN UP
1. Remove grout residue and haze as you work. If working alone, only grout approximately
6-10 square feet before initial cleaning. If working as a team, one person should grout,
with the other(s) cleaning immediately behind the rst person. Cleaning should take place
within 5 minutes of application and before grout begins to set-up.
2. Using a clean grout sponge, rinse the sponge in the pail of water that contains the dish
soap and wring out. Sponge should be lightly damp. Do not use a saturated, dripping
sponge. Standing water should not be present on the tile surface or puddled in the grout
lines. Excessive water used during clean-up will dilute the grout and prevent proper curing.
STEP 1: Work in a circular motion to loosen the grout residue on the tile surface, tooling the grout joints smooth. Use both
sides of the sponge. Rinse sponge in upper part of the bucket and wring again. Do not plunge sponge to the bottom of the
pail where the urethane has settled so as to avoid circulating the urethane through the water.
DO NOT overwash grout joints by using excessive scrubbing and/or water.
3. Using a clean microber sponge, rinse the sponge in the pail of water containing clean,
fresh water only (no dish soap). Do not use a saturated, dripping sponge. Standing water
should not be present on the tile surface or puddled in the grout lines. Excessive water
used during clean-up will dilute the grout and prevent proper curing. DO NOT over wash
grout joints by using excessive scrubbing and/or water.
STEP 2: Make a diagnonal pass over the tile surface with one edge of the microber sponge
and then the other edge of the sponge, ensuring you remove all excess grout and residue.
Rinse and repeat. Rinse sponge in upper part of the bucket and wring again. Do not plunge sponge to the bottom of
the pail where the urethane has settled so as to avoid circulating the urethane throughout the water. Change the water
frequently to prevent the grout residue from being redeposited on the tile surface. Change water after each 100 square
feet, with each new bucket of grout, or when water is dirty or milky in appearance.
4. Check work as you clean. Repair any low spots with additional grout.
NOTE: Wipe up any spilled water immediately. Do not allow water to sit on grout joint surface or in un-grouted joints.
5. All grout residue is capable of being removed using the microber sponge. Remaining grout and/or residue on the
surface of the tile should be treated at this step for the most eective removal.

CURE TIME AND PROTECTION
1. Humidity aects the rate at which Urethane Grout cures more than temperature: the lower the humidity, the faster
the cure.
2. Under normal residential conditions, light foot trac is acceptable after 24 hours; normal household foot trac after
72 hours.
3. Wait 7 days before exposing grouted area to household cleaners (see Technical Data Sheet for Chemical Resistance
Properties Table).
4. Protect grout from stains and chemicals while curing.
5. Do not cover oor with cardboard, plastic, area rugs, etc. while grout is curing. Grout must be exposed to air to cure
properly.
SECONDARY HAZE REMOVAL
Allow cleaned tiles to dry then inspect the surface. If additional residue removal is necessary, use a urethane grout
haze cleaner (UGC or Krud Kutter). Wait 24 hours before using UGC or Krud Kutter ™. Make sure the grout is suciently
cured to withstand light nger pressure without losing form. Spray the urethane grout haze cleaner on a nylon scrub
pad designed for delicate surfaces such as the 3M™ Doodlebug ™ white cleaning pad or ScotchBrite nylon mesh pad.
Rub the cleaning pad lightly over the urethane haze on the tile being careful not to touch the grout joints. Excessive
haze may require repeated cleaning. Do not ood the surface with cleaner. Allow the urethane grout cleaner to rest on
the tile/stone surface for at least 3-5 minutes to ensure sucient penetration. After 3-5 minutes, rub the tile a second
time with the scrub pad. Then, use a damp sponge and clean water to remove lm and cleaner. Finish by drying the tile
surface with a clean towel or cloth.
