FasTop Multi WR (formerly known as Resuthane JT40) is a water-based resin render which can be applied to coves and walls which require significant protection from hard wearing concrete floors. Once fully sealed with FasTop Multi T150, it should maintain the exceptional standards of resistance already prevalent.

FasTop Multi WR is ideal for the food and drink sector, pharmaceutical, abattoir, dairy environments and more due to its resistance to all types of chemicals and the anti-slip properties allows floors to be safe in dry and wet conditions.

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 grease must be removed by mechanical means and detergent washing making sure all residue of the 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 of surfaces should be carried out using Resutack PU. Once the area has been primed the FasTop Multi WR should be applied immediately onto the wet primer. This will allow a chemical bond to form between the primer and the FasTop Multi WR which will provide a stronger adhesive bond to the substrate.


FasTop Multi WR 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.

NB. Cure times are extended at low temperatures.

Mix the coloured base component to an even consistency, ensuring the re-dispersion 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 homogeneous mix of the three components is achieved. Apply to pre-primed areas with a coving trowel to form the skirting as required.

Note: Due to the different aggregates used in this vertical grade material, a variation in surface texture and colour density must be expected. Where a closer colour match is required to adjacent surfaces then FasTop Multi T150 should be used to overcoat the FasTop Multi WR within 24 hrs of application.

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