Barrettine White Knotting - 250ml

Barrettine White Knotting is a 'clear' knotting made from White Shellac which reduces the discolouration of topcoats when sealing knots under wood stains, varnishes and light coloured paints. It can be used under solvent and water based paints but we'd always recommend you test this on a small area first. Nourish and protect your wood with Barrettine White Knotting which is to be used on knots and resinous areas prior to painting.
