Materials · Basecoat, one coat
Polyurea
The basecoat is the layer nobody ever sees and the one that decides whether the floor stays attached. Polyurea goes down straight onto the ground slab, soaks into the open profile, and stays flexible after it cures.

| Where we use it | Directly on the ground slab, under the flake |
Flexibility is the whole point
A concrete slab in an unheated space expands and contracts all year. A brittle coating bonded to a moving slab has two options: crack, or let go. Both look like peeling.
Polyurea keeps moving with the slab after it has cured. Through forty freeze and thaw cycles a year that is the difference between a floor and a repair job.
It needs an open slab to work
Penetration is what makes the bond mechanical rather than just adhesive. That requires concrete that has actually been opened up with diamonds first. On a closed, troweled or acid etched slab there is nothing for it to key into.
Right choice for
- Basecoat under a flake broadcast
- Slabs that move seasonally
- Cold weather installation
Wrong choice for
- Use as a topcoat, it is not UV stable on its own
- Application over a closed slab
