Zinsser Grade 1 is a high performance, mould resistant paint for the interior decoration of walls and ceilings in traditional and historic buildings, including churches, castles and period properties.

Designed for period properties and historic buildings, Zinsser Grade 1 solves the moisture problems that plague traditional structures. This all-in-one primer, sealer and finish eliminates the need for separate undercoats, drying to recoat in just two hours. Its breathable formula allows walls to release trapped moisture, preventing the flaking and cracking common in older homes. The paint film dries tension-free, further reducing future damage. With built-in biocide protection against fungal growth and exceptional stain-blocking power against soot, smoke, water and nicotine marks, Grade 1 performs on plaster, concrete, limewash, distemper and more. Nearly odourless and ready to transform period interiors without extensive surface preparation.
