Application Instructions

Surface Preparation: Area must be clean, dry, free of dirt and dust. Grout joint should be free of sealers.


  • For best results, grout no more than 10 ft2 (0.93 m2) at a time.
  • Press grout diagonally into joints holding float at a 45-degree angle. Make sure that joints are completely filled.
  • Remove all excess grout off tile by holding float at a 90-degree angle and drawing diagonally across tile.
  • For best results, wait 10 minutes before beginning clean up to allow the grout joint some time to firm up so it is not pulled out of the joint during clean up process. Do not wait longer than 40 minutes.
  • To clean, first soak sponge in cool clean water. Wring out most excess water, then pat the surface of the tile with the damp sponge to loosen the film. Next, rinse the sponge in water a second time and wring out excess water completely.
  • Use the damp sponge in a light, circular motion to smooth joints and clean film from the tile. Avoid using excessive amounts of water on the grout joints.
  • Turn sponge over to a clean side and draw diagonally across tiles to remove any remaining film.
  • For optimal results, follow these final clean-up steps: moisten a towel with clean water, wring out excess, then drag damp towel across surface diagonally. This will pick up remaining film.
  • If a light haze remains after cleaning, do not attempt to remove it with the sponge. Instead, leave the haze on the surface and remove the next day with a damp sponge. Haze will easily come off of most tile surfaces.
  • There is no need to seal TEC® Ready-To-Use Grout.

Note: If excess water is used in the sponge during clean up, minor cracks or pinholes can develop. If the grout is over-worked, it may appear to shrink down into joint. Should any of these things occur, simply apply a second coat to the affected areas. You must allow your initial application to cure for 24 hours prior to your second application.

  • Instruction For Use Over Premixed and Cement-Based Grout: To installll, existing premixed or cementitious grout must be clean, sealer free, and 1⁄8" (3 mm) lower than tile surface. If not: Remove existing grout with a grout saw to at least 1⁄8" (3 mm) below the surface of the tile. Make sure the joint is free of all dust and debris, then apply grout per instructions above.
  • Set-up Time: Light foot traffic after 24 hours. Allow 7 days to achieve final cure which includes hardness and stain resistance. ALLOW 7 DAYS BEFORE EXPOSURE TO WATER.
  • Clean-up: Clean tools and hands with warm soapy water while grout is still wet.
  • Maintenance: For routine cleaning of your grout, use a Neutral pH cleaner. Follow manufacturer instructions for dilution. Do not use acids, bleaches or vinegar for cleaning. Alkaline-based cleaners can be used for periodic heavy duty cleaning. Follow manufacturer instructions for dilution.
  • Not for exterior use
  • Not for use with polished marble, metal tiles and most glass tiles*, travertine or Saltillo tile.
  • Certain tile surfaces may be stained when grouted with colored grout. Follow tile manufacturer recommendations or test.
  • Use on grout joints from 1⁄16" up to 1⁄2" (1.6 up to 12 mm) wide.
  • Do not grout over existing epoxy grout Installations.
  • Maintain temperature range of 60°-100°F (16°-32°C) during use and drying.
  • Freeze-thaw stable. If frozen, thaw completely and remix before using.
  • Not for use in swimming pools or exterior applications.
