Review: Concrete floor crack & seam sealant - If you have cracks and expansion seams on concrete floors, this self leveling polyurethane compound is great. Good adhesion and complete sealing. Be sure to use backer rod to fill most of the space on seams and large cracks. Backer rod means you use far less on this compound and also prevents three point adhesion in expansion seams.
Review: A driveway saver for sure. - We have tried several different types of sealers for the cracks in our driveway. This one has worked the best first used it three years ago and it is still holding up. Just finished sealing several long and wide cracks again. Love the self leveling since I am not the steadiest at applying it. We live in Rockies and it gets cold and hot in the same day. The caulk seems to expand and contract and still maintain the seal.
