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 25 N/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 10mm deep by 5-10 mm wide. These should be inset approximately 150 mm 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 Terrazzo 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 Base Part A pouch and then the FasTop Multi Colour Pack pouch contents into a mixing bucket or directly into a rotary drum mixer, mix thoroughly for one minute then add the FasTop Multi Hardener Part B pouch. If a separate bucket has been used pour the combined mix into a rotary drum mixer and add the FasTop Terrazzo aggregate component steadily, until a homogeneous mix of the four components is achieved.

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

Application

Apply immediately to prepared areas. When priming a surface this should be tack free and FasTop Multi Terrazzo should be applied at the required rate as soon after mixing as possible. Level between battens as necessary with a steel float. Where ease of cleaning is very important alongside slip resistance, the final finish can be smoothed by back rolling with a short nap roller. A single pass with the weight of the roller is usually sufficient. Delay can result in variation in surface finish, colour and add to application problems.

The surface should be protected from temperatures of less than 10ºC and moisture in the early stages of cure and should be allowed to cure typically for a minimum 48-72 hours at 20ºC before grinding can commence.

The FasTop Multi Terrazzo should have an initial dry rough grind using 50–100 metal bond diamonds, on a 3 heads planetary grinder. This is typically a dry grind removing 0.5–2 mm off the screed surface to expose the coloured decorative aggregate. This is followed by successive finer cuts to remove cutting marks and scratches typically using 200# grit to 400# grit diamonds. Care must be taken to use appropriate equipment to achieve the necessary finish and then the floor should be thoroughly cleaned and vacuumed prior to the grout coat being applied.

Repeat rough grinding and the grout coat steps if a high number of large voids still exist. After the grinding process FasTop Multi Terrazzo is grouted with Resuflor GC and sealed with Resupen WB Clear or can be further polished until grain 1500 or 3000.

See Sherwin-Williams FasTop Terrazzo System Guide for recommended floor systems.

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

NB: Cure times are extended at low temperatures.
