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.
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 PR01 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 flooring systems. Porous substrates may require double priming.
Acrydur PR01 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 -10°C to 35°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 Peroxide hardening powder into the container of Acrydur resin (see table below). Mix until the Peroxide is completely dissolved.
Hardener addition % guidance
Temperature | Hardening Powder | Pot Life/Minutes | Hardening Time |
---|---|---|---|
-10°C | 7% | 22 | 60 |
0°C | 5% | 15 | 40 |
20°C | 3% | 12 | 30 |
30°C | 2% | 10 | 25 |
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 PR01 should be applied evenly by roller, brush and squeegee avoiding any puddles. If a squeegee is used, the surface must always be rolled with a paint roller afterwards.
Matt and heavily absorbent patches should be reprimed as required wet on wet before hardening ensuring any pores are closed up.
