Surface Preperation

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

Existing Grout: Deep cleaner remove any existing topical sealer using Heavy Duty Cleaner & Acrylic Finish Stripper (FC305). Follow directions to achieve required results.



Remove the seal and cut the tip of the spout. Inset a small piece of sponge into the extremity of the spout. This piece of sponge will regulate the sealer in the bottle when up-side down and allow an easier application by just squeezing the bottle to release the sealer. Put the spout back into place and put the tip of the bottle on a grout joint. Apply a coat of sealer by gently squeezing the bottle and taking it along the joints. 2 thin coats are usually sufficient. Allow 30 to 45 minutes to dry between coats or until surface is totally dry. Remove spills or excess on tiles with a damp cloth as soon as the sealer on the joints is dry to the touch. If it is too difficult, you may use FCS Solutions Ltd. Heavy Duty Cleaner & Acrylic Finish Stripper (FC350). For wall grout joints apply sealer using a fine point brush.
