Moisture Resistant Systems for Swimming Pools

Promat has developed a moisture resistant ceiling and wall lining system specifically for use in swimming pool and other high humidity environments.


The high performance system, which can be used to form a seamless ceiling and wall lining, incorporates Promat MASTERBOARD® moisture resistant calcium silicate board, a corrosion resistant metal support structure and a Steridex® protective coating.

System benefits include:

  • Seamless system providing greater design flexibility
  • Tested and warranted system backed by three component manufacturers
  • Proven performance when subjected to high humidity and corrosive atmosphere
  • Hygienic surface prevents the growth of mould and bacteria
  • No risk of warping, disintegration or failure of ceiling or wall lining
  • Steridex® protective coating forms the final decorative finish
  • Smooth or textured, matt or gloss, hygienic or biocidal surface finish
  • BBA certification


Wall linings can be formed using a similarly treated metal support system to ‘dry-line’ block walls, using Promat MASTERBOARD®. These linings can be finished with Steridex® protective coating or can be tiled using suitable adhesive and grout.

The system has been successfully installed throughout the UK and Ireland in more than 200 swimming pool projects over the last 10 years.
