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 the 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 the surface is totally dry. Then remove spills or excess on tiles with a damp cloth when the sealer on the joints is dry to the touch. If it is too difficult, you may also use Heavy Duty Cleaner & Acrylic Finish Stripper (FC350). For wall grout joints apply sealer using a fine point brush.
