Zinsser Grade 1 is a high performance matt white restoration interior coating. Water based, mould resistant paint for the interior decoration of walls and ceilings in traditional and historic buildings, including churches, castles and period properties. Specially formulated to tackle all the problems that can be found in period properties. A primer, sealer and finish in one, Grade 1 requires no washing down and no additional primer. In addition it is re-coatable in just two hours. It’s vapour permeable film allows the painted substrate to breathe. The finish contains a biocide to protect the dried coating against fungal degradation, whilst the paint film dries with zero tension which reduces the likelihood of future cracking, flaking and peeling. Grade 1 can be applied on many different substrates: plaster, concrete, mortar, chalky materials, distemper, lime wash and whitewash: on walls, ceilings, doors, trims, windows and cabinetry. It is virtually odour less and offers unparalleled stain blocking, hiding stains from soot, smoke, water, graffiti and nicotine. Coverage - 10m² per litre, Colour and Finish - Matt White.
