Sherwin Williams Resuprime MVT

Sherwin Williams Resuprime MVT is a two-component epoxy resin primer that is tolerant of residual moisture in concrete floors.

Best Uses

Sherwin Williams Resuprime MVT enables earlier access onto new concrete substrates for the application of screeds, coatings and other floor coverings including carpets, tiles, vinyl and wood.

• Ease of application
• Application onto substrates with hygrometer readings up to 97% ERH
• Low odour
• Excellent adhesion
• Solvent free

Sherwin Williams Resuprime MVT is available as a standard Clear or as Stirling Grey and is also used for existing concrete slabs where there is no damp-proof membrane or where a degree of moisture tolerance is required for a resin floor system being installed.

Recommended for use on "green" concrete, concrete substrates with no DPM, polymer screeds and cementitious underlayments.

Application

New Concrete Floors: New concrete must be clean, sound, dry, fully cured and surface laitance removed by vacuum enclosed shot blasting or mechanical grinding, a minimum strength of 25N/mm² is required.

Existing Concrete Floors: Remove all dirt, oil, grease, old paint or any other surface contaminants by vacuum enclosed shot blasting, scarifying or mechanical grinding. Fats, oils or greases must be removed by mechanical means and detergent washing and making sure all residue of detergent is washed and removed by rinsing with clean water. Local repairs should be carried out using Resuscreed PA.

Existing Floors (previously coated): All previous coatings and loose floor paints must be removed by mechanical preparation as described in the above section and primed as specified. If the old resin flooring cannot be removed then please consult with our technical team for advice on intercoat adhesion and suitability, as it may not be compatible with the existing floor coating.

Where Resuprime MVT is applied to masonry/concrete surfaces, care must be taken to ensure that surface preparation is thorough but does not disfigure the surface.

Priming

Where the Relative Humidity of a substrate exceeds 85% ERH Resuprime MVT should be specified and selected on the basis of hygrometer readings in accordance with BS 8203:2017.

Application

The mixed unit should be applied immediately by roller, brush or squeegee with a consistent procedure. Floor areas should be cross-rolled to ensure even application and to minimise roller marks.
