R.S. Dampshield FH

R.S. Dampshield FH is a faster curing version of R.S.Dampshield setting in less time providing overcoat times of 6 hours. Both products are two-component epoxy resin membranes that are tolerant of residual moisture in concrete floors. This enables earlier application of screeds, coatings and other floor coverings including carpets, tiles, vinyl and wood.


Product Benefits:


  • Enables resin coatings to be applied onto new concrete much sooner than the normal time required for concrete to dry
  • Easily applied by brush, roller or trowel edge
  • Can be applied onto substrates with hygrometer readings up to 97% RH
  • Completely solvent free and low odour
  • In ambient conditions over-coat times of 6 hours

Where to use:


R.S. Dampshield FH can be used on concrete floors and fine concrete screeds, of not less than 50mm thick, in the case of un-bonded screeds. The surface must be of sufficient quality, continuity and mechanical strength to ensure an even coating.


R.S. Dampshield FH may also be applied to polymers, screeds and certain types of smoothing underlayments; provided these are well bonded. Such underlayments must be stable to the effects of water. If not the concrete floor must contain an integral damp-proof membrane to prevent further ingress of water from the ground.

When laid onto a concrete surface where there is no damp proof membrane (DPM) or where damage may have rendered the DPM ineffective, due consideration must be given to the possible presence of hydrostatic pressure, and the consequences of creating a barrier layer resulting in the pressure /water flow being directed elsewhere.
