General Surface Prep

USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when handling product.

Tiled surface and joints must be clean, and adhesives must be dry. When grouting both vertical and horizontal substrates together, protect horizontal substrate from excess wash water that may fall during the cleaning of grout on walls by covering the floor area prior to grout installation on the walls. 

Health Precautions

Contains ethylene glycol, 2-butoxy ethanol and acrylic latex. Avoid contact with eyes and skin. Do not take internally. CAUTION: KEEP OUT OF REACH OF CHILDREN. Use in well-ventilated areas. Wear chemical resistant gloves and eye protection. FIRST AID: If eye or skin contact, flush thoroughly with water. In case of respiratory tract irritation, move person to fresh air. If irritation persists, seek medical attention. If ingested, do not induce vomiting. Seek medical attention. This product contains a chemical or chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Limitations to the Product

  • Should not be installed when ambient or surface temperature is lower than 50° F (10° C) or above 90° F (32° C).
  • Some ceramic, glass, metal, marble or stone tiles can be scratched or damaged by the silica aggregate filler. Perform a test on a small area prior to use.
  • Tile or stone with high absorption, surfaces that are porous or rough, textured surfaces and some types of porcelain tile may require sealing prior to grouting to prevent possible staining. See the General Surface Prep section for details.
  • Do not use Fusion Pro with irregularly shaped or spaced tile or stone, such as pebble stones, where joint widths or depths exceed 1/2".
  • Not for use in either industrial applications or in areas subjected to harsh or continuous chemicals, high heat or high-pressure cleaning. For heavy industrial tile installations, use CEG-IG 100% Solids Epoxy Grout.
  • Not for use over concrete slabs with high moisture emission rates.
  • Not for use in steam rooms or submerged applications (swimming pools, spas, water features and fountains).
  • Not for use in movement joints or changes of plane in the tile installation. In these areas us an appropriate caulk or sealant such as Commercial 100% Silicone Caulk or Polyblend® Ceramic Tile Caulk.

Mixing Procedures

Ready to use – no mixing required.

Application of Product

  • Pre-seal natural stones and porous or rough textured tile and fogged glass with Aqua Mix® Grout Release, Aqua Mix® Sealer's Choice® Gold or TileLab® SurfaceGard®.
  • Fusion Pro cures by evaporation. Ensure setting material has dried, substrate does not have a high moisture emission rate and work area has adequate ventilation.
  • Only spread for 3-4 minutes, typically 20 sq. ft. (1.85 m²) before cleaning grout off the tile surface. More can be spread in cool, damp conditions; less in hot, dry conditions.
  • Do not allow Fusion Pro to dry or skin over prior to final cleaning. If grout dries on surface during installation, lightly moisten and wait 2-4 minutes, then gently clean tile surface using sponge or white nylon scrubber.

Fusion Pro is a new technology grout with significant advantages over traditional grouts, requiring modified installation techniques to achieve best results. Do not apply or clean up this grout as typically done with cement or epoxy grout.

Lightly dampen tile surface before spreading. Do not allow any water to puddle on the surface of the tile or in the grout joints. Use a medium to hard grout float to spread grout. Spread grout and fill joints for 2 minutes, typically 10 sq. ft. (0.9 m²) increments. More grout can be spread in cool, damp conditions; less in hot, dry conditions. Drag the edge of the float diagonally across the tile to remove excess grout while leaving the joints full. Cleaning of grouted area should begin immediately, before grouting next section.

Use a lightly damp grout sponge held flat against the tile. Working the entire 20 sq. ft. area, use a circular motion and moderate pressure to loosen any grout that is still adhered to the tile surface. Limit the number of times you rinse out the sponge at this stage. The residue on the sponge will help break up and soften residue on the surface of the tile. Do not over scrub as it may pull grout out of the joints. Grout joints must remain full. In areas where the Fusion Pro is well-adhered, leaving a visible film that is not releasing from the surface of the tile, re-apply a small amount of Fusion Pro. Slurry the grout with the clean up sponge until clean (approximately 30 seconds). Wipe the area clean with a rinsed, lightly damp sponge, followed by a lightly damp microfiber towel.

Once grout on tiled surfaces has been loosened, thoroughly rinse and wring out the sponge.
Wipe the sponge once across the grouted tile diagonally to clean the face of the tile and create smooth consistent grout joints.
Flip the sponge over and continue cleaning the next area.
Rinse, wring and repeat until you have dragged a clean sponge face across the entire 20 sq. ft. area of freshly grouted tile.

Lastly, drag a lightly damp microfiber towel across the surface for final clean up. Do not allow Fusion Pro to dry or skin over prior to final cleaning. If grout dries on the surface, lightly moisten and wait 2-4 minutes, then gently clean the tile surface using a sponge (or a white nylon scrubber) to remove residue. If streaks or residue remain after 2 hours, use diluted Aqua Mix® Grout Haze Clean-Up, Aqua Mix® Non-Cement Grout Haze RemoverTileLab® Grout & Tile Cleaner or TileLab® Heavy Duty Stripper & Cleaner and clean with a sponge or scrub pad. Additional instruction and videos available online.

Curing of Product

Allow 24 hrs until light traffic, and 7 days at 70° F (21° C) and 50% relative humidity before intermittent water exposure (such as a shower enclosure). Lower temperatures and higher humidity will slow the cure times. Covering Fusion Pro immediately after grouting will extend the cure time. Grout should be allowed to cure 24 hours before covering with a highly-porous protective material to ensure a timely cure to protect the surface from other trades traffic. Lower temperatures and higher humidity will slow cure times. Exterior applications must be protected from rain, snow and other wet conditions for at least 7 days with temperature above 50° F (10° C). If inclement weather is expected, protect the work area with tenting at least 1 foot (30 cm) above the finished surface to allow air flow. Enclose and protect exterior installations and maintain >50° F (10° C)  temperatures for at least 72 hours for proper cure.

Sealing of Grout

Fusion Pro is a stain resistant grout.  Sealing is not necessary. If sealing of the tile is necessary, use a water based sealer like AquaMix Sealer's Choice Gold and wipe off excess on grout joints. Do not use solvent-based sealers with Fusion Pro.

Cleaning of equipment

Clean tools and hands with water before material dries.

Handling & Storage

Protect grout from freezing. If product freezes, return to room temperature and use as directed. Do not stir if partially frozen.

Product Maintenance

Clean with a neutral cleaner such as Aqua Mix AquaKleen, Aqua Mix Concentrated Stone & Tile Cleaner or Tilelab Grout & Tile Cleaner.
