Ask a Question
  • A: This product helps to seal a very porous or weak floor, therefore improving the bond between the surface and the paint, and also reducing loss of coverage. If you dont think the concrete is weak or overly porous I would recommend using our etchant instead on a bare floor before painting to remove surface laitance which can affect  how the paint bonds.
