This is a generic tech help for stone floor and grout sealing. It covers ceramic and porcelain tile floors.


  1. Sweep floor to remove any abrasive debris.
  2. Mix sealer, according to directions. Apply using Grout Wand.
  3. Allow sealer to completely penetrate into the grout 5-15 minutes.
  4. Liberally apply a second coat following steps 2 and 3 if needed.
  5. Wipe up all sealer from the surface of the tile. Use a clean dry lint-free towel.
  6. If sealer was not completely wiped off and residue appears, wipe entire surface with a towel dampened with sealer. Use a white nylon pad to loosen residue and follow with a clean white absorbent towel to remove.
  7. A full cure is achieved after 24-48 hours; foot traffic may begin in 4 hours.
