A translucent, colourless knotting for use under oils, varnishes and lighter coloured paints, where the use of Patent Knotting may cause some ghosting. Some water-based products may not adhere to White Knotting. Compatibility should be checked on an off-cut before use. Note: If knots are exuding excessive resin, it is advisable to remove and make good with sound timber or suitable filler/stopper. Always test before use to ensure it’s suitability with paints. For use internally and externally.
