Zinsser Allcoat Exterior Matt is a high-performance, water-based paint designed for a wide range of exterior surfaces including timber, metal, plastic, masonry, concrete, and UVPC. This durable paint forms a breathable, low-maintenance, water-shedding coating that is touch dry in just one hour. It offers excellent resistance against cracking, blistering, and flaking, with superior color retention that resists fading. Unlike many other colored masonry paints, Allcoat Matt will not darken when wet. It contains biocides to protect against fungal degradation and can bridge surface gaps up to 0.5mm. This paint is self-priming on most surfaces and can be applied to previously painted surfaces without sanding, even over glossy finishes. Two coats are recommended for optimal protection and a long-lasting beautiful finish.
