Tri-Seal Epoxy Resin Coating

A solvent free, low odour, two-part epoxy resin coating, typically used as a surface damp proof membrane and water vapour suppressant. Tri-seal is suited for use as a damp proofing system beneath raised access floors, in plant rooms and bunded areas. It is also suitable for application on damp surfaces, such as sand/ cement and concrete floors subject to rising damp or containing residual construction moisture. The system can be used as a vapour barrier, applied internally to concrete, for example, to attain a Grade 4 basement, as described in BS 8102.

Tri-seal can be blinded over with Triton coarse and fine aggregates to provide slip-resistant finishes or to form a key for renders, bonded screeds and tiles. Tri-seal is suitable for areas on the negative side of construction only where it will not be subject to positive hydrostatic pressure.


  • Part 1: Low viscosity epoxy resin, reactive dilutent, flow promoters and oxide red pigment.
  • Part 2: Low viscosity epoxy curing agent and accelerator.
