CPR 825 – MMA Colour Stable Coating

Description

MMA Colour Stable Coating

CPR 825 – MMA Colour Stable Coating is a two pack, fast curing coating designed to provide a dust-free, seamless floor finish with protective and decorative properties. The inherent slip resistance of the coating may be enhanced by the incorporation of a suitable anti-slip dressing aggregate.

CPR 825 – MMA Colour Stable Coating allows a fast return to service.

Typical Properties

• Tough and abrasion resistant
• Colour Stable
• Very good chemical resistance
• Rapid curing minimises down times
• Suitable in wet areas
• Hygienic and easily cleaned
• Cures at low temperatures
• Hot water and fat resistant to 80°C

Directions for Use

Surface Preparation 

• Concrete surfaces 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, and existing paint finishes, etc.
• Blow holes and defective concrete shall be made good using a proprietary repair compound e.g. CPR 711 – MMA Concrete Patch Repair Mortar.
• Suitable mechanical treatment, such as vacuum grit blasting, is the preferred treatment prior to application as this ensures a mechanical ‘key’ which will optimise adhesion.
• 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 412 – MMA Metal Primer 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 406 – MMA Concrete Primer , applied by brush or roller, at a nominal rate of 0.3kg/m².
• Long nap lambswool rollers are recommended for primer application.
• Allow primer to cure for a minimum of 40 minutes.
• Steel surfaces shall be primed with CPR 412 MMA Metal Primer as soon as practicable after blasting.

Mixing

• CPR 825 – MMA Colour Stable Coating is supplied as a two pack material consisting of the BASE component, and the CATALYST component. Incorporate the CATALYST component into the BASE component under mechanical stirring, and mix for 1-2 minutes.

Application

• Apply CPR 825 – MMA Colour Stable Coating using short nap perlon, or smooth lambswool rollers at a nominal rate of 0.30kg/m².
• Following a minimum of 1 hour apply a second coat at the same nominal rate.
• Should a slip resistant or skid resistant finish be required then broadcast an appropriate aggregate onto the first coat within 10 minutes of application.
• Following a minimum of 1 hour sweep off excess aggregate and apply a second coat of CPR 825 – MMA Colour Stable Coating.
• NOTE: CPR 825 – MMA Colour Stable Coating may be applied at greater thicknesses should service conditions warrant it.

Equipment Cleaning

• Clean equipment with  CPR 200 – MMA Tool Clean Solvent immediately after use.

Curing
