This Ronseal Knot Block wood primer and undercoat in white, 750ml, is made to stop knots and resin from showing through your paint. It suits anyone painting interior wood such as doors, windows and skirting boards.
It does two jobs in one tin, priming and undercoating, and it covers bold colours and dark marks too. Ronseal says it is ready to paint over in four hours, and it can go on bare or previously painted wood. The 750ml tin covers 4.5m² with two coats, so it is a sensible, low price way to get a clean finish over knotty pine.
