WaterShield is a clear, penetrating sealer that repels water, grease and oils. For use on porous surfaces such as concrete, stucco, brick, block, and stone, WaterShield is non-toxic, odor-free and safe for both indoor and outdoor use. This can also be used outdoors on vertical wood surfaces that are raw wood or those stained with most water-base stains such as AFM Durostain. Not for decks or horizontal fence railing.

Why we like it
It's easy to use, has no odor and creates a lasting seal on all masonry surfaces. It also does not change the sheen of what it's applied to. It works well to protect American Clay plaster in damp areas; in fact, we have successfully used WaterShield on our American Clay backsplash in the kitchen – including behind the stove – and on the walls around the vanity in our powder room.
