Sherwin-Williams Floorcoating Resuprime PU

Solvent-free polyurethane primer

Resuprime PU is a two-component, solvent-free polyurethane primer designed for use on car parking decks and other areas where a more flexible solution is required. The product has excellent adhesion to a wide variety of substrates and imparts a degree of flexibility that complements the properties of the Resudeck ID and Resudeck TD systems.

Advantages

  • Good flexibility
  • High bond strength
  • Will cure at temperatures down to 5°c
  • Low VOC

Recommended Uses

  • Intermediate Car Park Decks
  • Top Car Park Decks
  • Underground Car Park Decks

Preparation

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 make 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 existing floor coating.

Priming

Open and porous substrates will require priming with Resuprime PU, on dry substrates only with less than 75% ERH reading. Where the Relative Humidity of a substrate exceeds 75% ERH Resuprime MVT should be specified and selected on the basis of hygrometer readings in accordance with BS 8203:2017. 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
For further information please refer to individual product datasheets.

Application

The ambient temperatures of the areas should not be allowed to fall below 10°C throughout the application and the curing period, as this could have an adverse effect on the appearance and colour of the system. The surface temperature must be above 5°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.

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

The mixed unit should be applied immediately by squeegee, roller or brush to achieve an even smooth finish.

The surface should be protected from temperatures of less than 5°C and moisture in the early stages of cure. This could adversely affect the surface finish of Resuprime PU.

Application of the relevant system being used should be undertaken no longer than 24-48 hours after the primer has been applied. Beyond this, the primer will need preparation to ensure good adhesion between the primer and the system.
