RSL Resuprime MVT Epoxy Concrete Primer Overview

RSL Resuprime (formerly known as RSL Dampshield) is a faster curing 2 pack epoxy resin primer, it enables even earlier access onto new or existing concrete substrates for screed and coating applications on carpets, tiles, vinyl and wood. 

  • Enables resin coatings to be applied onto new concrete much sooner than the normal time required for concrete to dry
  • Easily applied by brush, roller or trowel edge
  • Can be applied onto substrates with hygrometer readings up to 97% RH
  • Completely solvent free and low odour
  • In ambient conditions over-coat times of 6 hours

Preparation

New Concrete Floors: New concrete must be clean, sound, dry, fully cured & surface laitance removed by vacuum enclosed shot blasting or mechanical grinding, a minimum strength of 25N/mm sq. 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 & detergent washing and make sure all residue of detergent is washed and removed by rinsing with clean water. Local repairs should be carried out with Resuscreed PA.

Existing Floors (previously coated): All previous coatings & 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 existing floor coating.

Where Resuscreed PA 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 & selected on the basis of hygrometer readings in accordance with BS 8203.

The number of coats to be applied is chosen in accordance with the following table.

ERH% - Required Coating Thickness 
75-85 - 1 coat of Resuprime MVT at 200 microns per coat 
85-92 - 2 coats of Resuprime MVT at 200 microns per coat 
92-97 - 3 coats of Resuprime MVT at 200 microns per coat

For further information please refer to recommended individual product data sheets.

Application

The ambient temperatures of the areas should not be allowed to fall below 15°C throughout the application & the curing period, as this could have an adverse effect on the appearance and colour of the system. Surface temperature must be above 10°C. Where possible it is recommended that the application area is heated to a minimum temperature of 15°C ideally to allow the ambient and substrate temperature to stabilise prior to installation.

Mixing: Pre-mix the base component to a uniform consistency then mix the entire contents of the base with the hardener. If a separate mixing bucket is being used for mixing ensuring all contents of both components are removed from the buckets supplied. Mix using a slow speed electric mixer for approximately two to three minutes until the two components have fully combined.

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

Coverage rates may vary depending on profile and porosity of the substrate
