Microtech Penetrating Sealer Directions

Surface Preparation

New Grout: wait for 7 to 14 days to allow proper curing of grout before applying the sealer (Refer to grout manufacturer’s recommendation).

Existing Grout: First deep clean or remove any existing topical sealer using Heavy Duty Cleaner & Acrylic Finish Stripper (FC350).

Floor Application: Apply a thin coat of sealer evenly on the surface with an FCS Mop (FC230) and an application Mop Cloth (FC225) or a White Scrub Pad (FC210). Then allow the sealer to penetrate the surface for 15 minutes. Do not allow the sealer to pool on the surface by wiping the surface with a dry cloth after 15 minutes. Allow sealer 1 hour to completely dry afterward. Apply a second coat in the same manner. Two coats are generally sufficient.

Wall & Backsplash Application: Make sure there is no accumulation of sealer on the top edge of the tiles to avoid apparition of streaks during the drying period. The most effective method is to saturate the surface by misting or spraying the sealer. Then let the sealer penetrate for 5 minutes and dry tile surface with a dry cloth. One coat is generally sufficient.

To verify if sealer protection is adequate: To assure protection is adequate test the sealed surface once it has dried. Put a few drops of water on the surface and then wait a few minutes. If the surface does not darken, then there is no water penetration and the protection is adequate.
