How do you waterproof laminate countertops?
Gel gloss will smooth, shine and seal laminate countertops. Mix 1 tsp. mild dish detergent into a sink of warm water. Apply 1 tbsp. of gel gloss to a sponge, and wipe the gloss over a section of the laminate countertop, using circular motions. Wipe the gel gloss from the laminate countertop with a clean cloth.
