Epoxy DPM

A two-part, solvent-free, damp-tolerable, epoxy-based damp-proof membrane (DPM) that suppresses residual construction moisture and rising dampness in concrete and sand/cement screeds and can be used in situations where the relative humidity level is above 85%.

The high quality, low viscosity formulation is suitable for application onto damp substrates, allowing for the speedy application of flooring, coatings, membranes, levelling compounds and screeds.

Epoxy DPM is quick and simple to use and can be applied over cementitious screeds and concrete. It is applied by brush or roller in two different coloured, gloss coats, or in just one coat if applied above Epoxy Primer.

    Key Benefits

    • Very damp tolerable.
    • Can be applied to concrete and screed 7 days after placement.
    • Solvent free.
    • Excellent vapour barrier.
    • High-bond DPM that provides a barrier to vapour and prevents osmotic blistering.

    Typical Applications

    Typical Applications

    Priming of damp, non-porous concrete and screed to provide a DPM and vapour barrier, prior to the application of moisture-sensitive flooring, coatings, membranes, levelling compounds and screeds in the following scenarios:

    • Car parks
    • Warehousing and storage
    • Garages
    • Plant rooms

    Suitable Substrate

    Suitable Substrate

    Correctly formed, compacted and prepared:

    • Concrete of at least 7 days old
    • Screed of at least 7 days old
