Dulux Acratex® Roof Sealer WB 15 L

Used after cleaning sound concrete roof tiles, Dulux Acratex Roof Sealer WB is the water-borne primer that locks down the surface and balances porosity so every subsequent coat of Dulux roofing paint performs at its best. Supplied as a milky liquid that dries clear, it forges a uniform key for Dulux Acratex Roof Membrane Next Generation and complements other specialist basecoats in the range, such as Dulux Acratex Terracotta Roof Primer 15 L.

Why choose this sealer?

Water-based acrylic technology – low odour, very low VOC (< 10.1 g/L) and simple water clean-up.
Fast back-to-work times – touch-dry quickly and ready for over-coating in as little as two hours at 25 °C, 50 % RH; keeps commercial schedules tight.
Excellent adhesion – penetrates and consolidates sound concrete tiles, giving the roof membrane maximum hold and colour retention.
Rainwater safe – once cured, the coating is suitable for roofs used in potable-water collection systems.
Part of a complete Dulux paint system – engineered to work with Dulux Acratex Roof Membrane and related primers for different substrates.
