Dulux Acratex Roof Primer MX Plus 15 L

Dulux Acratex Roof Primer MX Plus is an advanced water-based primer formulated for new or weathered galvanised surfaces, including Zincalume, Zincanneal, aluminium and aged Colorbond. Metal roofing needs a primer that bites into the surface and seals it before a membrane system goes on, and MX Plus is the Acratex basecoat for that job. The improved formulation gives better water resistance than the original Acratex Roof Primer MX, which is what makes it suited to both the cold southern states and the humid northern states.

Application Guidelines

Make sure the metal roof is clean, dry and free of contaminants, and remove any loose or flaking material. Apply the primer evenly with the chosen method, then let it dry before the topcoat goes on. Proceed with Dulux Acratex Roof Membrane as the finish. The grey basecoat gives the membrane a uniform key to hold onto.
