Performance & Benefits

Ultimate Multi-Surface Exterior Protection
AllCoat Exterior WB Matt Black is engineered for long-term decoration of wood, metal, masonry, plastic, concrete, cladding and UPVC surfaces. It forms a vapour-permeable, low-maintenance water-shedding coating that helps resist cracking, blistering and flaking under severe weather exposure.

Excellent Adhesion & Coverage
The self-priming paint bonds well to both new and previously painted surfaces — including many glossy coatings — without the need for sanding in most cases, saving time on surface preparation.

Strong Colour Retention & Flexible Film
The matt black finish offers excellent colour retention, helping the exterior appearance remain rich and uniform over time. Its flexible film can also bridge small surface imperfections and hairline cracks up to 0.5 mm wide.

Fast Recoating & Easy Application
Quick drying and a short recoat time (typically about 1 hour) allow efficient application of multiple coats within a single work session.

Recommended Applications

Ideal for use on exterior surfaces including:

• Timber and wood cladding

• Metal frames, gates and trims (previously primed or painted)

• Masonry, brick and concrete walls

• Plastic, UPVC and cladding panels

Surface Preparation & Application

4. Dry: Allow about 1 hour between coats under normal conditions.
