RSL Resuprime ESD (formerly known as Resustat CP and Resustat Primer) can be applied to wood, concrete, metal and synthetic floors. It is for application before static-dissipative resin flooring systems, which are ideal for industrial and domestic environments with high levels of electrical current. 

Resuprime ESD has a conductivity level of less than 0.050 M Ohms when tested in compliance with BS EN 61340.

Recommended Uses

• Food halls
• Breweries
• Abattoirs
• Operating theatres
• Pharmaceuticals
• TV studios
• Prior to applying any of the Resustat range

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/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 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 with 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.

Resuprime ESD can also be applied to existing coatings and to other cementitious screeds which should be clean and sound with an appropriate mechanical key for adhesion.

Priming

Resuprime ESD should be used as a conductive primer only and is normally applied on top of an already primed and sealed surface. The copper tape grid for the earthing should be applied prior to the application of the Resuprime ESD.

Open and porous substrates will require priming with Resuflor WB Clear or Resuprime ST may be used as primer on the 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.

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

Application

The ambient temperatures of the areas should not be allowed to fall below 15°C throughout the application and 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, ensure 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 roller or brush with a consistent procedure. Floor areas should be cross-rolled to ensure even application and to minimise roller marks.
