Choosing the right roof primer

A primer or sealer binds the surface and gives the topcoat something to grip. Using the wrong primer is one of the most common causes of a restoration coating failing early, so match the primer to the roof material and condition.

  • Concrete tiles: IRC Roof Protect WB Primer and CT Primer bind aged tiles and block calcium salt bleed. IRC Platinum Primer gives maximum adhesion and surface uniformity. RGL Roof Master suits heavily weathered and pitted tiles.
  • Terracotta tiles: IRC Roof Protect Terracotta Primer is formulated for unglazed terracotta. IRC Terracotta Glaze is a clear finish for cleaned terracotta roofs.
  • Metal roofs: IRC Metal Primer Plus for Colorbond, Klip-Lok and other metal roofing, and IRC Rust Inhibitor Primer for rusted areas.
  • Standard roofs on a budget: IRC Oz Prime and Roof Refresh High Build Primer with the Roof Refresh system.
  • RGL system: RGL Roof Primer, Roof Sealer and G-Sealer before RGL Nu Roof topcoats.

After priming, finish with roof paint from the same manufacturer's system. Spray equipment is in paint accessories. Check the product data sheet for coverage and recoat times.
