5. INSTALLATION
Surface Preparation
Read entire label before using. Use only as directed.
Test in a small inconspicuous area with a 24 hour cure
time to determine ease of application and desired
results. Allow new grout installations to cure for at least
72 hours prior to application. Make sure surface is clean,
thoroughly dry and free of waxes and coatings. Surface
temperature should be 50°F–80°F (10°C-27°C). Ensure
work area is well-ventilated during application and until
surface is dry. Keep children and pets out of the area
until surface use resumes.
Directions
1. Shake well and apply STONETECH®Heavy Duty
Grout Sealer directly onto grout lines and joints to
thoroughly wet surface using a paint pad, roller or
brush. Avoid applying sealer on unintended surfaces.
2. Allow sealer to completely penetrate into the grout, 5–
15 minutes.
3. Liberally apply a second coat following steps 1–2.
4. Wipe up all sealer from the surface of the tile. Use a
clean, dry, lint-free, cotton towel or mop to remove
excess sealer.
5. If sealer was not completely wiped off and a residue
appears, wipe entire surface with a towel dampened
with sealer. Use a white nylon pad to loosen residue
and wipe surface with a clean, white absorbent towel.
6. A full cure is achieved after 24-48 hours; surface use
may begin in 4 hours. If use of the surface must
resume sooner, cover the treated surface with red
rosin paper to protect it until full cure is achieved.
7. Clean tools used during application with water.
Expected Wear
•Up to 5 years on interior surfaces
•Up to 3 years on exterior surfaces

8. MAINTENANCE
Highly alkaline, acidic, ammoniated, or abrasive cleaners
are not necessary for daily maintenance and may also
degrade the STONETECH sealer used, adversely
affecting stain resistance. Tile and stone routine cleaning
with a neutral pH cleaner such as STONETECH Stone &
Tile Cleaner is recommended. For tough or difficult to
remove soil use STONETECH KlenzAll™ Cleaner and a
nylon scrubbing pad or a long handled stiff bristle brush.
Please note: Prior to using any cleaning material on a
tile, stone, etc. installation, test a discrete area or scrap
piece of tile to ensure desired results. For additional
information, please refer to the TDS 262 Stone and Tile
