Description
Ardex MVS 95 (12kg) One Component Residual Moisture Vapour Suppressant
ARDEX MVS95 is a ready-for-use, one-component, water-based, dispersion coating supplied in pre-gauged 12kg units. ARDEX MVS 95 is supplied pigmented blue to indicate uniform coverage and is waterproof when fully cured.
ARDEX MVS 95 is designed to suppress residual construction moisture in cementitious substrates including suitably prepared power-floated concrete and cement/sand screeds.
ARDEX MVS 95 is designed for use as a two-coat system. When fully dry, two coats of ARDEX MVS 95 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.
ARDEX MVS 95 can be used on heated screeds that have been installed and commissioned in accordance with BS 8204 Part 1, taking into account the recommendations in Part 4 of BS EN 1264.
It is not suitable for use on direct-to-ground substrates without a functioning, structural damp-proof membrane. Please refer to the ARDEX DPM 1 C or ARDEX DPM 1 C R datasheet for applications where no structural damp-proof membrane exists or the relative humidity is above 95% RH.

- Drying time will be extended under cool and/or humid conditions.
- Colour: Blue
- Coverage: 12kg maximum unit coverage per 2 coat application (m²)
- 90% RH = 36m²
- 95% RH = 27m²
Application:
STIR WELL BEFORE USE. Do not add water or dilute ARDEX MVS 95, it is ready for use. Do not use this product when the air temperature is below 100C and/or the substrate temperature is below 50C. Apply an even coat with a suitable short pile roller in one direction over the appropriate area (see table below).
Depending on the film thickness applied, the porosity/absorbency of the subfloor and the ambient conditions, ARDEX MVS 95 may be dry in as little as 30 minutes at 20°C. These times may be extended at lower temperatures and/or in high humidity conditions. When the first coat is touch dry, apply the second coat at right angles to the first.
It is essential that the applied ARDEX MVS 95 is a continuous film and is free from pinholes, cavities or thin patches, otherwise, additional applications may be necessary. Allow to dry to a tack-free film. This will take approximately 1 hour at 200C in good drying conditions. ARDEX MVS 95 should be overlaid with 3mm, to a maximum of 10mm, of an ARDEX Smoothing Compound to protect the film and to provide a uniform absorbent layer for subsequent floorcovering application with an appropriate ARDEX Flooring Adhesive.
ARDEX MVS 95 must not be trafficked between coats and before the levelling and smoothing compound is applied. No more than 24 hours should be allowed to elapse.
Packaging, Storage and Shelf Life:
ARDEX MVS 95 is supplied in a 12kg container and is ready to use. It can be roller applied directly out of the container. Part-used containers should be resealed after use and the contents will remain usable for at least 6 weeks if stored under good conditions
Store in dry conditions out of direct sunlight & between 5°C and 30°C. Protect from frost. ARDEX MVS 95 has a storage life of not less than 12 months in the original unopened containers.
