Directions for Use

Surface Preparation Concrete

  • Concrete surfaces shall be a minimum of 7 days old.
  • Ensure that the concrete is clean and free from dust, laitance, grease, oil, curing compound, and existing paint finishes, etc.
  • Suitable mechanical treatment such as vacuum grit blasting or mechanical scabbling is recommended to ensure the removal of contaminants and to provide a mechanical ‘key’ for the primer.
  • Ensure that no standing water is present on the surface.

Mixing

  • Pour the contents of the Catalyst container into the Base container, add the Filler component, and thoroughly mix, preferably by mechanical means.

Application

  • Apply by squeegee to distribute evenly over the floor, and then use a long nap lambswool roller to achieve a nominal application rate of 0.4-0.8kg/m², depending on substrate absorbency.
  • Allow to cure for a minimum of 30 minutes prior to applying any other of the CPR MMA product range.
