Surface 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 making sure all residue of detergent is washed and removed by rinsing with clean water. Local repairs should be carried out using FasTop Multi BU.

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.

Anchor Joints: To ensure the maximum bond is achieved, grooves must be cut into the perimeter of the subfloor, typically 20mm deep by 5-10mm 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 the FasTop Multi DP laid to the full depth forming a perimeter anchorage.

Primer

Primers are optional for this product dependant on substrate surface conditions and porosity. If required FasTop Multi Primer should be used which utilises the FasTop Multi components as detailed on the FasTop Multi Systems brochure and the FasTop Multi Primer product data sheet.

Apply FasTop Multi Primer by medium nap roller, brush or squeegee. Work the primer well into the surface ensuring it is fully wetted out and then roll to complete an even coating without any ponding. Two coats may be required to eliminate any dry patches and to create an even sealed surface. The primer should be worked into and around the anchor joints whilst avoiding to filling these with resin.

For further information please refer to recommended individual product data sheets.

Mixing

Add the FasTop Multi Part A component (base) and then add the contents of the FasTop Multi Part D (color package) in a mixing bucket or directly in a rotary drum mixer, mix thoroughly for a minute then add the FasTop Multi Part B (hardener) component and mix for 1 minute. Add component DP Part C (aggregate) constantly, into the mixing bucket or into the mixer with rotating blades until a homogeneous mixture of the components is obtained.

FasTop Multi DP should be applied immediately after mixing to prepared areas.

Application

FasTop Multi DP may be applied to substrates with a surface temperature in the range of 5-20°C and a relative humidity of 40% to 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 DP 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.

The FasTop Multi DP mixed compound should immediately 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.

Once laid the surface should be broadcast with selected aggregates (Quartz, Granite or Carborundum) to obliteration by hand or mechanical blower at a rate of 2 kg/m² to saturation using one of the following three aggregate options. :-

• FasTop DP Light Duty 0.7-1.2mm Aggregate scattered evenly
• FasTop DP Medium Duty 1.2-1.8mm Aggregate scattered evenly
• FasTop DP Heavy Duty 1-3mm Aggregate scattered evenly

Continue broadcasting to excess until the floor appears dry and even and then allow to cure for 12-24 hours. Once cured any remaining loose aggregate should be removed, and the surface sealed by the application of FasTop Multi T150 by squeegee, roller or brush at the following coverage rates in line with the aggregate used as the scatter.

• FasTop DP Light Duty 0.7-1.2mm Aggregate = 0.4 - 0.6 kg/m²
• FasTop DP Medium Duty 1.2-1.8mm Aggregate = 0.7 - 0.9 kg/m²
• FasTop DP Heavy Duty 1-3mm Aggregate = 1.0 - 1.2 kg/m²
