Direction for Use
Surface Preparations Concrete
- Concrete shall be a minimum of 21 days old and/or the residual moisture content shall be below 6%.
- Ensure that the concrete is clean and free from dust, laitance, grease, oil, curing compound, existing paint finishes, etc.
- Blow holes and defective concrete shall be made good using a proprietary repair compound e.g. CPR 719 Concrete Patch Repair Mortar.
- Suitable mechanical treatment, such as vacuum grit blasting is the preferred treatment prior to application as this ensure a mechanical ‘key’ which will optimise adhesion.
Surface Preparations Steel
- Steel surfaces shall be shot blasted or grit blasted to a nominal Sa 2.5 Swedish standard.
- All dust shall be removed prior to coating application. A coat of CPR 410 Metal Primer – Epoxy WB shall be applied as soon as practicable after blasting, in order to obviate the possible occurrence of ‘flash rusting’.
Priming
- Concrete surfaces shall be primed with a coat of CPR 403 Primer for Concrete Repair Mortars – Epoxy WB applied by brush, roller, or airless spray, at the nominal rate of 0.25kg/m².
- Long nap lambswool rollers are recommended for primer application.
- Allow primer to cure for a minimum of 10 minutes.
- Steel surfaces shall be primed with CPR 410 Metal Primer – Epoxy WB (see Surface Preparations above).
Mixing
- CPR 704 – Coloured Quartz Epoxy Screed is supplied as a three pack material consisting of; the RESIN component, the CURING AGENT component, and the COLOURED QUARTZ component.
- Add the CURING AGENT component to the RESIN component and mix thoroughly, preferably by mechanical means for a minimum of 2 minutes.
- Pour the contents into a mixing vessel, and add the COLOURED QUARTZ component whilst stirring.
- A low speed drill with paddle attachment may be used, or else a forced action mixer e.g. Creteangle type.
Application
- Spread the CPR 704 – Coloured Quartz Epoxy Screed to the desired thickness, and trowel finish.
Sealing
- The application of a clear sealer is recommended to reduce tendency towards staining and dirt pick up, and thereby ensure optimum ease of cleaning: Apply 1 coat of CPR 902 PU Screed Sealer, single pack, water-based polyurethane sealer at a nominal rate of 0.15litres/m². CPR 902 PU Screed Sealer will provide a satin or matt finish.
Curing
- Allow to cure for a minimum of 10 hours @ 20°C prior to overcoating or light foot traffic access 7 days cure @ 20°C is recommended prior to exposure to chemicals.
- Curing will be slower at lower temperatures and faster at higher temperatures.
Equipment Cleaning
- Clean equipment with CPR 200 Tool Clean Solvent prior to curing of the coating.
Coverage
- A 25kg pack is sufficient to cover an area of 2m² at a thickness of 6mm.
