ARDEX MVS 95 Moisture Vapour Suppressant

A ready-for-use, one component, water based, dispersion coating supplied in pre-gauged 12 kg units. It is supplied pigmented blue to indicate uniform coverage and is waterproof when fully cured. It is designed to suppress residual construction moisture in cementitious substrates including suitably prepared power floated concrete and cement/ sand screeds. Designed for use as a two coat system. When fully dry, two coats produce a membrane which can accommodate hygrometer readings up to 95% RH and allows the subsequent application of ARDEX levelling and smoothing compounds without priming. The product can be used on heated screeds that have been installed and commissioned in accordance with BS 8204-1, taking into account the recommendations in BS EN 1264-4. It is not suitable for use on direct to ground substrates without a functioning, structural damp proof membrane. Refer to the ARDEX DPM, ARDEX DPM 1C or ARDEX DPM 1CR datasheet for applications where no structural damp proof membrane exists or the relative humidity is above 95% RH.
