New Concrete Floors:

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

Timber Floors:

Must be clean, sound, dry. Old clear varnish/topcoat must be removed/sanded prior to application, as it may affect the inter-coat adhesion with Resupen WB Clear.

Existing Concrete Floors:

Remove all dirt, oil, grease, old paints or any or 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. Local repairs should be carried out using Resuscreed PA or Resuscreed 45.

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 existing floor coating.
Where Resupen WB Clear is applied to masonry/concrete surfaces, care must be taken to ensure that surface preparation is thorough but does not disfigure the surface.
Where surfaces are found to be porous a primer coat may be required to achieve a uniform sealed surface


Resupen WB Clear may be applied directly to concrete or as a seal coat or top coat to a resin floor system specified in our datasheets where a primer is not required. When applied direct to porous substrates the surface may require priming. Dry surfaces may be primed with Resuseal WB Clear or Resuprime ST.
Where the Relative Humidity of the substrate exceeds 75% Resuprime MVT should be specified and 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 1coat of RESUPRIME MVT at 200 microns per coat
85-92 2coats of RESUPRIME MVT at 200 microns per coat
92-97 3coats of RESUPRIME MVT at 200 microns per coat


The ambient temperatures of the area should not be allowed to fall below 10°c throughout application and curing. Surface temperature must be above 5°c.

Mixing: Pre-mix the base component to a uniform consistency then add the entire contents of the hardener to the base and mix by using a slow speed handheld powered mixer and mixing paddle for approximately two to three minutes to achieve a consistent mixture.
Note: Do not use a separate mixing bucket as it may affect the mixing ratio.
Apply the whole mixed paint by using a spreading rake, roller and brush to achieve the maximum coverage within the specified pot life time frame.

Do not add water to this product.
Slip resistance can be improved by lightly broadcasting anti-slip aggregates on the first coat (after primer) whilst still wet and back rolling, at a rate of 50/100 g/m2. When cured apply the second Resupen WB Clear coat to secure the aggregates.
