Dulux Acratex Terracotta Roof Primer 15L

Dulux Acratex Terracotta Roof Primer is a high-performance water-based sealer engineered to prime both glazed and unglazed terracotta roof tiles before a membrane coating goes on. Aged and weathered terracotta loses its surface strength, and a sealer like this is what consolidates the tile face so the topcoat gets a stable, even base. The primer applies white and dries clear, so it is easy to see coverage while you work and the roof keeps its natural tile colour before the membrane is applied.

Recommended System Application

Clean and prepare the roof surface with high-pressure washing, then apply one full coat of Terracotta Roof Primer at 9-10 m2 per litre. Follow with two coats of Dulux Acratex Roof Membrane for a durable, long-lasting finish. The primer evens out porosity so the membrane covers evenly and holds its colour.

Applications

• Re-coating glazed and unglazed terracotta roof tiles
• Priming aged or weathered tile before an Acratex membrane system
• Roofs where a clear, breathable basecoat is needed under a coloured topcoat
• Commercial and residential roof restoration in Australian conditions

What You Need To Complete The Job

Pair the terracotta primer with the matching Roof Membrane topcoat, and for sound concrete tile roofs use the Roof Sealer WB as the basecoat instead. Finish the ridge with Dulux Acratex Roof Pointing. Browse the full Paint range for the complete system.

Frequently Asked Questions

Why prime terracotta tiles before coating?

Terracotta is porous and weathers unevenly, so a bare tile absorbs a topcoat patchily. The primer binds loose particles and evens out porosity, which gives the membrane a stable base and a uniform finish that lasts longer.

Does it change the tile colour?

No. It applies as a milky liquid and dries clear, so the natural terracotta colour shows through. The colour comes from the membrane topcoat that goes over the top.

How long until I can apply the membrane?

The primer is touch dry in 20 minutes and can be re-coated after a minimum of 2 hours at standard conditions. That keeps a roof restoration moving in a single day.

What surfaces does it suit?

It is made for correctly prepared glazed and unglazed terracotta roof tiles. For concrete tile or metal roofs, choose the matching Acratex basecoat for that substrate instead.
