ALLCOAT EXTERIOR GLOSS Zinsser AllCoat Exterior Gloss is an ultimate performance, mould resistant paint that offers supreme protection to all exterior surfaces: wood, metal, masonry, plastic, concrete and cladding. It forms a vapour-permeable, low maintenance, water-shedding coating that is recoatable in 1 hour.  The paint is self priming and can be applied to previously painted surfaces without sanding, even glossy paints or those coated with bitumen, tar varnish or creosote. For most jobs, there is no need to purchase a seperate primer. Zinsser AllCoat Exterior Gloss gives excellent resistance against cracking, blistering and flaking.
