WPA-1500-line.png

WPA 3460 is a single component primer based on polyether polyol and modified MDI isocyanate. The primer is a polyurethane pre-polymer with a surplus of isocyanate which reacts with the moisture in the substrate to cure the product. The product was designed as a low viscosity concrete primer for preparing substrates prior to applying the WPA 3400 spray applied membrane.

  • Very high bond strength.

  • Deep penetration into concrete.

  • Brush, roller or spray applied.
