Step 1: Ensure surface is clean. Using the scrubbing brush and dustpan, remove any debris from dried grout line.
Step 2: Push the clear plastic lock on Selleys White For Life Grout Sealer trigger clockwise to the open position. Spray liberally onto grout, saturating the surface. Allow to penetrate grout for 1 hour.
Step 3: Wipe off overspray from face of tiles, using a clean white cloth or paper towel.
Step 4: Apply a second coat of sealer for maximum protection. Ensure that this overspray is wiped off within 2 hours of application to prevent sealer drying on the tile surface.
Step 5: Allow to dry for at least 24 hours before exposing sealed grout to water on shower walls.
Step 6: Re-seal grouted surfaces every 12 months for ongoing protection.
