STEP 1. We recommend doing a test on a small area first; allow it to cure for 24 48 hours to determine the desired results.

STEP 2. Before you apply, make sure the surface if clean, dry and free of residues.

Do not dilute Nano4-Grout with water, as it is not required.

STEP 3. Pour Nano4-Grout into a clean plastic container and use a brush for the most economical application to apply on the grout as spraying may waste the liquid. Apply 2 coats (wet to wet). Apply the 2nd coat before the 1st coat dries while it’s still wet – usually within 3 – 5 minutes. Once completed, use a cloth and wipe off any excess residue off tiles. Let it dry for 24 – 48 hours before allowing contact with water.

Nano4-Grout offers a long life protection of up to 5 years for new surface and when applied correctly according to instructions and maintained according to Nano4Life’s maintenance guide.

However, you may need to re-apply earlier depending on the usage and for optimum results.


  • For the best results apply generously on the surface and make sure the coatings are wet
  • Avoid using the shower of the treated grout and use a second shower if possible to allow the treated surface to cure within the desired time frame (24 – 48 hours)
  • Once applied in the bathroom, leave the doors and windows open for better ventilation to assist in the curing process
  • If you’re unsure please visit for our application video or contact us.


  • Apply when surface temperature is between 5 – 30OC
  • Avoid moisture contact with the surface after application until fully cured for 24 – 48 hours for optimum results
  • Wear gloves and protective clothing
  • Wash hands after application
  • Store in a cool and dry location away from direct sunlight
  • Keep out of reach of children
  • PH Value 14 or above cleaner can destroy the effect
  • Nano4-Grout does not protect against etching, wear and high water pressure 50 bar and above
