CP470 is a water based flexible coating system, formulated to provide effective protection to plaster and masonry as well as for as a protective and decorative coating to soffits, walls and upstands within concrete and masonry buildings/structures.
CP470 is used as a protective and decorative coating to:walls and masonry structures as well as to walls and upstands within concrete and masonry buildings/structures, including:
- car park structures
- sheltered balconies
- covered walkways
- Excellent anti-carbonation properties
- Ideal for use in areas requiring a high level of cleanliness
- Water vapour permeable: allows substrate to breathe
- Smooth jointless / seamless finish
- Fire resistance: Class ‘O’ in accordance with UK Building Regulations
- Non-static and easily cleaned
Surface Preparation
- All surfaces to be coated must be clean, dry and free from loose friable material and any other contaminants likely to impair adhesion.
- As a minimum, it is recommended that all surfaces to be coated should be power washed. Further preparation may be necessary.
- In order to provide a continuous pinhole free coating, concrete exhibiting honeycombing or blowholes should be ‘bagged in’ using a suitable levelling mortar.
Application Conditions
- Ensure adequate through ventilation during and after application to assist drying.
- Application temperature range +5°C to +30°C, relative humidity <85%.
- Do not apply if frost is expected before the coating has dried.
Method of Application
- The product is self-priming onto correctly prepared plaster, blockwork and brickwork. For other substrates, a trial application should be made to confirm satisfactory adhesion.
- Apply a minimum of two coats of CP470 by brush, roller or airless spray.
- Allow 2-4 hours between coats in good drying conditions.
- Spray equipment - Graco Ultra 1500 or similar, 6.17 spray tip and 60 or 100 mesh filter, pressure: 2800 - 3000 psi/19 - 21 MPa.
