We've sanded our floorboards which were previously untreated. We then used knotting solution. Then did 2 coats of homebase primer and sealer (white) and we've just done 1 coat of Ronseal Diamond Hard Floor Paint (white).
Our problem is that there are marks coming through the paint which look like beige streaky dirt marks. We thought that after the first coat of floor paint these would stop.
Does anyone know what this could be and how to stop it?!
