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 Acrydur RM01 and Acrydur RM02.

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.

Where Acrydur CV01 is applied to concrete surfaces, care must be taken to ensure that surface preparation is thorough but does not disfigure the surface.

Priming/Application Conditions

Acrydur PR01 is for priming substrates prior to the application of Acrydur CV01. Porous substrates may require double priming. To enhance adhesion the primer application can be lightly scattered with sand (approximately 0.3 – 0.8 mm in size) at an approximate rate of 0.3 kg/m².

Acrydur CV01 is supplied in 25kg pails. Before mixing ideally precondition the Acrydur CV01 paste, Peroxide and selected filler or quartz to a temperature of approximately 15 °C to 20°C.

The application temperature should be 0°C to 35°C throughout the application and the curing period.

Mixing

Peroxide is added to Acrydur CV01 paste first of all followed by the selected filler or quartz immediately before application. The hardening powder must always be stirred in to create an even homogenous consistency in the corresponding mixture. The stirring time will depend on the type and the condition of the mixing equipment used and on the temperature of the material.

Prior to use, stir the Acrydur to obtain an even distribution of the paraffin contained in the product. Pour the appropriate ratio of hardening powder into the container of resin (see table below). Mix until the Peroxide is completely dissolved.

Hardener addition % guidance

NB: The quantity of hardening powder is always related to the amount of resin

Hardening powder must not be added to the reactive resin and resin/filler mix until immediately before application.

The hardening powder must always be stirred in and allowed to dissolve in the pure resin. The stirring time will depend on the type and the condition of the mixing equipment used and on the temperature of the material.

Application

Acrydur CV01 should be spread coarsely to the desired thickness using a trowel and then should be formed, compressed and smoothed using a coving trowel for a consistent coving with no pores or trowel marks remaining.

The application of the system requires consistent and even technique to ensure good compaction of the mix and to avoid pores and air bubbles within the stated tolerance of fillers and resin and depending on the thickness of the application.

For coving thickness of more than 10 mm and less than 20 mm, a first half thick cove must be installed for curing as to avoid any overheating. The final coving to follow as soon as the first layer has cooled down.
