DELTAPrime 2K SF Primer is a two component, solvent-free, medium viscosity epoxy primer specifically designed for sealing and priming concrete substrates.

DELTAPrime2K SF is ideal for solidifying porous and weak concrete substrates and can be combined with quartz sand to make a fast curing hard patch repair material.


  • Formulated at 1:1 ratio by volume for easy application with brush, spray or roller.
  • Penetrates deeply into concrete surface
  • Solvent-free. Non-hazardous.
  • Exceptional adhesion to correctly prepared concrete, steel and most common construction substrates.

Typical Uses

  • As a penetrating concrete densifier and primer prior to the application of DELTA protective linings.
  • As a patch repair material when combined with either quartz sand or DELTAPrime Filler.
  • As a base coat for DELTA floor coatings
