  • 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.
