Blackfriars Patent Knotting 250ml

Painting knotty and resinous areas is no longer a problem with Blackfriar Patent Knotting. It’s made from pure shellac and methylated spirit and is ideal for new wood or wood stripped or burnt-off prior to priming but is not suitable for use with translucent coatings due to its dark orange colour.
