Did much research online to find a product to seal a brick chimney in our finished attic (which was flaking all over the place). Purchased this Acrylic Waterproofing Sealer and it worked like a dream! It is very watery, and it was suggested to be sprayed on, but I brushed it on with a thick paintbrush, 2 coats as suggested. Goes on milky, dries clear (satin finish). Absolutely fantastic! So happy. Will be using it in a friend's house to seal a brick wall, too. Goes a long way.
This was a great product for my interior brick walls. Seemed to seal them up nicely while not affecting the finish too much.
Shipping was great, and very quick. Packaging was superb.
