Best Uses

Centrecoat MMA Primer FG exhibits outstanding adhesion to concrete, as well as steel, masonry, and marine plywood. With fast curing characteristics, Centrecoat MMA Primer FG allows rapid application of subsequent Centecoat MMA Freezer Grade coatings.

Application

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. 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.

Pour the contents of the CATALYST container into the BASE container and thoroughly mix, preferably by mechanical means.

Apply by squeegee to distribute evenly over the floor, and then use a long nap lambswool roller to achieve a nominal application rate of 0.25-0.30 Kg per m2. Allow to cure for a minimum of 40 minutes prior to applying any other of the Centrecoat MMA Freezer Grade product range. If an interval of more than 8 hours between primer application and subsequent overcoating is anticipated then the primer shall be scattered with fine silica sand before hardening.
