FasTop Multi SL45 (formerly known as Resuthane SL45)is ideal for environments that are hard wearing, but require a smooth and continuous floor system. It can be used on small and large areas alike, is non-dusting and non-taint. It is highly hygienic and does not gather bacteria.

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.

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 our technical team for advice on intercoat adhesion and suitability, as it may not be compatible with existing floor coating.

To ensure the maximum bond is achieved, grooves must be cut into the perimeter of the subfloor, typically 5mm deep by 10mm wide. These should be inset approximately 150mm from, and running parallel with the walls and adjacent to any doorways, plinths etc. Including any finished edge i.e. both sides of a day work joint. The groove must have a neat square edge and theFasTop Multi SL45 laid to the full depth forming a perimeter anchorage.

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

For further information please refer to individual product data sheets.

FasTop Multi SL45 may be applied to substrates with a surface temperature in the range of 5-20°C and a relative humidity <90% RH , with a minimum air temperature of 8°C and no condensation. Do not pre-warm this product as working times will be substantially reduced if materials are warm.

When the primed surface is tack free,FasTop Multi SL45 should be applied at the required rate as soon after mixing as possible. (Delay can result in variation in surface finish, colour and add to application problems).

NB: Cure times are extended at low temperatures.

Mix the coloured base component to an even consistency, ensuring the redispersion of any settled pigment. Thoroughly scrape the contents of the base and hardener components into the same container and mix thoroughly for one minute. Pour the combined base and hardener into a rotary drum mixer and add the aggregate component steadily, until a hom*ogeneous mix of the three components is achieved.

When thoroughly mixed the compound should be poured evenly over the appropriate area to be covered (monitoring rate of coverage to ensure correct depth of screed). Low floor temperatures and reduced thickness may reduce the flow properties of these products. Work out the mix rapidly and evenly over the area with a notched trowel, pin rake or similar to the appropriate thickness. Roll immediately with a spiked roller to achieve an even smooth surface and remove entrapped air.

NB: Spiked rolling should be undertaken immediately after trowelling. Do not re-roll later.

FasTop Multi units should be applied consistently with mixes from the same batch used consecutively where adjacent areas are being laid.
