Applications & Uses

Application Area
Suitable Substrates
  • Proper preparation of the tile and joint surfaces is important and will help promote a quality installation. The joints between the tiles should be free from foreign materials, and be at least 2⁄3 of the thickness of the tile in depth. High ridges of adhesive or mortar should be raked out. Any spacers used should be removed.
  • Tiles should be held firmly in place according to manufacturer’s instructions before grouting.
  • Power Grout is a highly pigmented product and it is critical to protect surrounding areas from exposure to pigment. Be sure to protect cabinets, countertops, and other surrounding areas which might become stained by the pigment present in the grout.
  • This is especially important with dark colors which include black pigment. Due to rough surface texture or high porosity, some tiles require sealing prior to grouting.

Limitations Information
  • Jobsite and grout temperature should be 50o-80oF (10o-27oC) for optimal installation.
  • Do not install during temperatures below 50°F (10°C).
Application Instruction

For best results pour water in a bucket and then add powder. In a clean mixing container, add Power Grout to clean, cold water as specified below:

Size Water
25 Ibs. (11.34 kg) 2.25-2.75 quarts [72-88 fl. oz.] (2.13-2.60 L)
10 Ibs. (4.54 kg) 3.6-4.4 cups [28.8-35.2 fl.oz] (0.85-1.04 L)
7 Ibs. (3.18 kg) 2.6-3.1 cups [20.2-24.6 fl. oz.] (596-729 mL)
  • Start with the low-end water range. Add water per instructions. Do not over water.
  • Mix with a drill (350 rpm max.) and mixing paddle attachment for a minimum of 2 minutes. Drill mixing is preferred and provides optimal results – hand mixing will yield acceptable results.
  • Do not add more water until mixture has been mixed for 2 minutes. Product consistency will loosen with mixing. Add water with care not to exceed recommended range. Under conditions that can result a shorter pot life, (i.e. hot weather), mix at the top end of the water range to provide more working time.
  • Allow to slake in bucket for 3-5 minutes.
  • Remix with drill and mixing paddle for a minimum of 1 minute
Recommended Applications
  • Fully pack the joints between the tiles by spreading Power Grout with a clean, hard rubber float. Work only a small area at one time [5-10 sq. ft. (0.5-1 m2 )]. Apply in a diagonal direction across the joint lines to prevent the grout from being dragged out of the joints.
  • Go over each area several times from all directions to make sure that the grout is fully packed in. Remove any excess grout from the surface of the tile by holding the float at a 90° angle to the surface and moving it diagonally across the joints. Repeat the entire process until all joints are grouted.
  • When grouting very absorptive tiles e.g. bisque tile and/or for thin grout lines, mix Power Grout to the highest water ratio. Additionally, pre-moistening the tile edges by spraying or wiping with a damp sponge or towel will help ensure that the grout retains water needed to properly cure.
Cleaning Instructions
  • Allow grout to firm up 15-30 minutes under normal conditions before final cleanup. Check for firmness by touching the grout with your finger. If there is transfer, wait 5 minutes and test again. Wet a grout sponge in a pail containing cool, fresh water and wring out.
  • Loosen the grout on the tile surface by moving the sponge in a circular motion across the tiles. Then use the sponge to smooth the joints. Completely rinse and wring out the sponge. Wipe diagonally across the tiles to remove grout residue.
  • Use each side of the sponge once, then rinse, completely wring out and repeat. Change the water frequently. Allow the grout to dry 30 to 60 minutes and remove all remaining grout residue from the tiles with a damp sponge or terrycloth towel.
  • Protect the finished installation from foot traffic or impact for at least 4 hours.
  • Wait 24 hours before mopping, routine cleaning or shower use. Do not expose to stains, complete water immersion or freezing for 7 days. No need to seal grout. If tile or stone is to be sealed after grout is installed, use a compatible solvent based sealer.
  • Test a small area of the tile/stone and grout to ensure you achieve the desired results. If a water-based sealer is required, consult Technical Support for a list of approved sealers. Allow grout to cure for 72 hours before sealing.
