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.
