Dulux Acratex Roof Primer Surfacer 15L

Dulux Acratex Roof Primer Surfacer is a high-build, water-based acrylic primer designed to restore aged and pitted concrete roof tiles. Concrete tile roofs lose their surface as they weather, and the Surfacer fills the minor imperfections so the roof presents a smooth, even face for the topcoat. It is the Acratex basecoat for the Roof Membrane Next Generation system on concrete tile, and its light grey colour gives the membrane better coverage than a clear basecoat would.

Application Guidelines

Make sure the concrete roof tiles are clean, dry and free of contaminants, then apply the Surfacer evenly with the chosen method. Let it dry for a minimum of 4 hours, then apply Dulux Acratex Roof Membrane as the topcoat. The high-build body is what fills the pitting and leaves a level base for the finish coats.

Applications

• Restoring aged and pitted concrete roof tiles
• Preparing concrete tile roofs for the Roof Membrane Next Generation system
• Roofs collecting rainwater where a potable-water-safe primer is needed
• Coastal and industrial areas needing a salt- and pollution-resistant basecoat

Frequently Asked Questions

What is a primer surfacer for?

It is a high-build primer that fills minor imperfections in aged, pitted concrete roof tiles, giving the membrane topcoat a smooth and even base. That levels the surface instead of just sealing it.

Why is it light grey?

The light grey colour provides better coverage for the topcoat than a clear basecoat, so the finished roof colour builds more evenly in fewer coats.

How long until I can topcoat?

It dries in about 4 hours before the topcoat can be applied. That is the minimum recoat window at standard conditions, which keeps a concrete roof restoration on a tight schedule.

Is it safe for rainwater collection?

Yes. It is formulated to be potable water safe, so it is suited to roofs used for rainwater collection as part of the Acratex system.
