Moisture barrier timber flooring adhesive

Epoxy based two component moisture barrier and sealer, to be used on certain porous substrates prior to the application of Soudal's timber flooring adhesives.

Open technical data sheet

  • Two component epoxy sealer
  • Moisture resistant
  • Porous and non-porous substrates
  • Suitable for underfloor heating
  • High shear, compressive and tensile strengths
  • Supresses rising damp and residual construction moisture. Ideally suited for preliminary treatment of sandy or powdery (high) absorbing mineral subfloors, such as cement bounded subfloors, concrete, calcium-sulphate bounded (anhydrite) and levelled subfloors. Also suitable on wooden subfloors, chipboard, terrazzo, ceramic tiles and metal.

Open technical data sheet

  • Epoxy Sealer EPR-31P should be acclimatised to room temperature before installation. Punch repeatedly through the plastic plug and base of the upper container which contains component B (e.g. with a long screwdriver). Allow the B component to drain fully into Component A and mix the components for at least 2 mins. Use a variable speed electric drill with a mixing paddle attachment. Ensure thorough mixing including the walls and floor of the container to achieve a homogeneous mixture. Always mix one package at the time (A-component + B-component). Never deviate from the prescribed mixing ratio between A and B component. Every deviation of this mixture ratio will affect the curing of the sealer and the final mechanical properties. Epoxy Sealer EPR-31P must be applied within 30 minutes after mixing. Apply the primer, undiluted from a bucket, to the subfloor by means of a paint roller or a brush. Do not pour the primer onto the subfloor to prevent puddles. In case of very porous and highly absorbing subfloors with rising dampness a second layer of sealer is recommended. Apply the second layer of sealer crosswise after the first layer has dried completely. Throw in quartz sand immediately after applying the second layer (approx. 2k/m², granule size 0,3 – 0,7 mm). Allow the epoxy sealer to dry completely prior to further activities to the subfloor. Not allowing for proper drying adversely affects the final result. Crater formation (in conjunction with Soudal Screed) and/or reduced adhesion might be the consequence.
