Installation Guide

TIP
Removing Residue
If Fusion Pro remains on the surface,
lightly moisten these areas and wait
2-4 minutes.
Then, gently clean the tile using a
sponge or a white nylon scrubber.
If streaks or residue remain after 2 hours,
use diluted Aqua Mix
®
Grout Haze
Clean-Up or TileLab
®
Grout & Tile Cleaner
and clean with a sponge or scrub pad.
For any dried residue that is noticed in
the days following the installation, use
diluted Aqua Mix
®
Heavy-Duty Tile & Grout
Cleaner or TileLab
®
Heavy Duty Stripper
& Cleaner with a sponge or scrub pad.
Tools Needed
• Medium to hard rubber grout float
• Grout sponges
• Microfiber towels

Use Clean Water
Use only clean, fresh water to prevent
grout haze.
Rinse and refill the bucket frequently –
every 30-40 sq. ft.

Important Notes
Because Fusion Pro
®
Single Component
®
Grout cures by evaporation,
installing Fusion Pro is different than other types of grout.
• The work area requires adequate ventilation.
• Do not cover the grouted surface during the drying period.
• The mortar for setting tile must be fully cured.
• The substrate cannot have a high moisture vapor emission rate.
†
• Tile and grout joints must be clean and dry.
• Do not add water to the grout.
• Do not mix the grout.
• Do not use Fusion Pro with irregularly shaped or spaced tile or stone, such as
pebble style mosaic tile, where joint width or depth exceeds 1/2" in any direction.
• Due to the varied tile finishes in the market today, always perform a test with Fusion
Pro on a sample of tile in ambient conditions similar to those you will be grouting in
before beginning the project.
• CUSTOM recommends using a grout release or sealer prior to all grout installations
for ease of clean-up and grout haze prevention.
†
The moisture vapor transmissions rate from the substrate should not be in excess of 5 lbs.
of water/day/1000 sq. ft., based on a standard ASTM F-1869 Calcium chloride test, or 80% rh,
based on ASTM F-2170.
