Concrete Block Sealer

This waterproofing sealer will help to prevent water from seeping through concrete blocks and cinderblocks. Not only that but mold, mildew and efflorescence growths are reduced and are easily cleaned off.

Available in a ready to use version, or an ultra concentrated version. The ultra concentrated version is mixed with 4 gallons of distilled water prior to application. Two coats are easily applied wet-on-wet (the second coat is applied immediately after the first coat while the first coat is still wet) with a sprayer, roller or brush. The concrete retains its natural appearance after sealing and will not yellow or fade with UV light exposure.
