Product Description

Centrecoat MMA Steel Primer has been developed as a primer for steel, galvanised steel, aluminium, and unglazed ceramic tiles. Use prior to any of the Centrecoat MMA range of coatings, mortars, and screeds.

Best Uses

Centrecoat MMA Steel Primer exhibits outstanding adhesion to steel surfaces, and the fast curing characteristics allow rapid application of subsequent coatings, mortars or screeds. Also suitable as a primer for ceramic and vitreous tiles prior to application of Centrecoat MMA coating products.

  • Rapid cure, even at low temperatures
  • Very good corrosion resistance
  • Excellent adhesion
  • Impervious to water
  • Pre-packed units ready for use
  • Easily applied

Centrecoat MMA Steel Primer is supplied as a three pack material, comprising pre-weighed amounts of Base, Catalyst and Adhesion promoter components.

Application of MMA Primer

Steel/Galvanised Steel: Any rust, mill scale and other contaminants should be removed by gritblasting to Sa 2.5. Reduced levels of surface preparation, e.g. wire brushing to remove loose rust, are permissible, but will lead to lower performance characteristics.

Ceramic Tiles: Abrade to roughen the surface, removing any dust.

Pour the contents of the Adhesion Promoter container into the Base container and thoroughly mix, preferably by mechanical means. Then add the Catalyst component and mix to a uniform consistency.

Apply MMA primer by squeegee, brush or roller at a nominal application rate of 0.25-0.30Kg per m2. Allow to cure for a minimum of 40 minutes prior to applying any other of the Centrecoat MMA product range. If an interval of more than 8 hours between MMA primer application and subsequent MMA overcoating is anticipated, or when priming ceramic tiles, then the primer shall be scattered with fine Quartz sand before hardening.

Clean equipment with Centrecoat MMA Tool Cleaner immediately after use.
