SeamsPerfect Base Coat is more than just a membrane, it is the only complete underlayment system specified for the concrete overlay industry.

This liquid applied, seamless, flexible acrylic membrane patches substrate cracks, assuring they will no longer telegraph through to the surface, minimizing costly customer call-backs.

Unlike putty or epoxy, SeamsPerfect Base Coat attaches and integrates seamlessly with itself, specialty concretes, and with sealers. It moves, bends and breathes making the substrate and overlay systems act as one.

These patented products, tested and used worldwide, are now available to the American market.
