It's a microporous, breathable coating that lets trapped moisture escape from brick and render while resisting rain getting in, so it protects the wall without trapping damp behind the paint film - and it's rainproof within about an hour of application in good drying conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan you use masonry paint on wood or metal?\u003c\/strong\u003e\u003cbr\u003eNo. Sandtex Smooth Masonry Paint is formulated for masonry surfaces - render, roughcast, pebbledash, concrete, building blocks and facing brick - not wood or metal. For those surfaces you'll need a dedicated wood or metal paint instead.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many coats of Sandtex masonry paint do I need, and how long does it take to dry?\u003c\/strong\u003e\u003cbr\u003eTwo full coats are recommended on bare or previously unpainted masonry (a sound, previously painted wall may only need one coat as a refresh). It's touch dry in 3-4 hours and can be recoated after 3-4 hours in good conditions - always check the tin for the latest guidance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere can I buy Sandtex masonry paint?\u003c\/strong\u003e\u003cbr\u003eRight here - every tin in this collection is genuine Sandtex Smooth Masonry Paint.
