Was easy to use. I used this to seal interior brick & mortar that we have as backsplash in kitchen and on our fireplace. Didn’t want someone to spill or splash something and possibly stain it. Should be easy cleanup now.

So far, so good. We'll see how it holds up, but application went well.

Easy to apply. Breathable barrier reduces small cracks due to freeze/ thaw cycle. Kept my sandstone chimney from becoming a sponge last winter.

great product
