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 RM.

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.

Where Acrydur ME04 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

Substrates should be primed prior to the application of Acrydur ME04. Acrydur PR01, PR02 & PR03 is for priming substrates prior to the application of Acrydur flooring systems. Refer to product datasheets for different substrates. Porous substrates may require double priming. The primer application should be lightly scattered with sand (approximately 0.7 – 1.2 mm in size) at an approximate rate of 0.3 kg/m².

Acrydur ME04 is supplied in pails or drums. Before mixing ideally precondition the Acrydur resin and the Peroxide as well as the fillers and quartz components to a temperature of approximately 15 °C to 20°C.

The application temperature should be 5°C to 30°C throughout the application and the curing period.

Mixing

Prior to use, stir the Acrydur to obtain an even distribution of the paraffin contained in the product. With pourable mixes, the Peroxide is the last component to be added in the mix. For mortars, add the Peroxide prior to adding the aggregate. 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

Hardening powder must not be added to the reactive resin and resin/filler mix until immediately before application. In the case of pourable mixes, the hardener should be the last component added, while for mortars or very thixotropic resins the full amount of filler or thixotropic agent should be stirred in first. The hardening powder must always be stirred in and allowed to dissolve in the corresponding mixture or 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 ME04 is applied squeegee and/or trowel to the primed and scattered surface. The mix should be spread coarsely to the desired thickness using a trowel or squeegee and then should be compressed and smoothed using a large smoothing trowel so that no pores and trowel marks remain in the floor. This product is particularly suitable for areas with higher slope as the mix does not level by itself.

The application of the system requires consistent and even technique to ensure the prevention of puddles and 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.
