Urethane Stone Color Enhancer Sealer – High Gloss Directions

Surface Preparation

Existing Surface: This sealer can be applied over a solvent based sealer but the surface must be scuffed with a Black Scrub Pad (FC205) first. Water-based sealers must be removed. First deep clean or remove any existing topical water-based sealer using Heavy Duty Cleaner (FC350). If for a new installation then use the Pre-Finish Cleaner (FC250).

New Installation: Apply 1 coat of sealer on the tiles before installation and/or grouting. Then apply a second coat after the manufacturer recommended grout curing time.


Using the FCS Mop (FC230) with the Application Cloth (FC225) apply 1 thin, even coat over the entire surface. Avoid air bubble formation while applying the sealer. Allow the surface to totally dry before applying another coat (4 to 6 hours). Application of two coats is usually enough. No polishing required.

Application on Vertical Surfaces: Make sure there is no accumulation of sealer in the joints or on the top edge of the time to avoid white streaks or white residue.

Caution & Limitations
