Resuflor SL ESD (formerly known as Resustat ESM) is ideal for industrial and domestic environments that carry high levels of electrical current. It should be installed at 3mm thickness for optimum performance and attractive finish. 

For conductivity leakage resistance, please see the product data sheet at the bottom of the page.

Recommended Uses

• Television studios
• Operating theatres
• Domestic studios
• Chemical plants
• Electronic industrial areas
• Pharmaceuticals

Preparation

New Concrete Floors: New concrete must be clean, sound, dry, and 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 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 the existing floor coating.

Priming

Open and porous substrates will require priming with Resuprime ST, 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.

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

Following the application of the Resuprime ST or R.S. Dampshield, copper tape strips are laid to form a grid system where the grids are no larger than 2m x 2m. The copper tape should be left exposed in areas to allow them to be earthed properly. Onto this a coat of Resustat CP is applied to provide a fully conductive layer under the Resuflor SL ESD. It is important to take a conductive reading of the cured Resustat CP before applying the Resuflor SL ESD.

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 coloured base component to a uniform colour, then mix the entire contents of 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, then add the aggregate slowly. Mix for a further 1-2 minutes until the aggregate has fully combined and there are no lumps. The mixed unit should be applied immediately.

Resuflor SL ESD should be worked with a trowel or float to achieve an even smooth finish. This is best achieved by the application of smooth, even pressure with the compound poured over the correct coverage rate after fixing the stop ends to control the flow of the material. Finally, roll the area with a spiked roller to achieve an even smooth surface and remove entrapped air. Do not re-roll the area later than 10-15 mins. The surface should be protected from temperatures of less than 10°C and moisture in the early stages of cure. This could adversely affect the flow, levelling and surface finish of Resuflor SL ESD.
