RSL FasTop Multi Bu (formerly known as Resufil) is a diverse product that can amend any imperfections that occurred earlier in the laying process. It can be applied in a variety of thicknesses, and can fill in potholes or back fill drains. It can also be used to create ramps.

Resufil's qualities make it ideal for hygienic environments such as food factories, kitchens and pharmaceutical plants that require a precise and clean finish. 

RECOMMENDED USES

• Infilling pot holes
• Back filling drains
• Creating ramps
• Food factories
• Kitchens
• Pharmaceutical and chemical plant processing
• Engineering factories

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.

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 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 1 coat of Resuprime MVT at 200 microns per coat
85-92 2 coats of Resuprime MVT at 200 microns per coat
92-97 3 coats of Resuprime MVT at 200 microns per coat

For further information please refer to individual product data sheets.

Application

Resufil 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 Resufil 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.

Mixing: Mix the base component to an even consistency. 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 homogeneous mix of the three components is achieved. Apply to pre-primed areas and level between battens as necessary with a steel float, alternatively a sledge can be used set at the required thickness and again finished with a steel float.

Apply Resufil in layers up to 60mm. Ensure that the material is well compacted throughout its depth and that each layer is keyed together. Allow 6-8 hours between layers. At the top surface, compact and finish to the required depth below the final surface. After a minimum of 8 hours Resuthane products can be laid to the required depth and finish.
