A fast drying primer for porous surfaces
A two pack solvent free primer especially designed to reduce suction on porous, very absorbent surfaces prior to application of Watco Chemi Coat or Watco Resiflow. It has significant benefits over traditional water-based primers in respect of penetration, substrate binding and curing. Not for use on non-porous surfaces.

Concrete and cementitious surfaces should be clean, dry and free of loose material. Watco Etch & Clean, an acidic preparatory agent, may be used to remove dirt (not grease) and loose cement deposits. Watco Bio D, a virtually solvent free virtually odourless degreaser, removes oil and grease. If the surface has to be wetted during preparation it should be left to dry as long as possible to allow the primer to penetrate. The primer will tolerate some dampness.
Pour the liquid contents of the two small tins (resin and hardener) into the larger outer tin and mix thoroughly until uniform in colour. The mixed components must be decanted into a scuttle and used immediately. If the mixed components are not decanted immediately, they will quickly become unusable and the mixing tin will become very hot and could pose a hazard.
Apply from the paint tray or scuttle using a medium pile simulated sheepskin roller working well into the surface. A brush may be used for cutting in. Apply in warm, well ventilated conditions.
