Barrettine Patent Knotting- is a quick drying Shellac in alcohol, which is applied over knots and resinous areas in wood, to seal prior to painting. For use internally and externally. Patent Knotting prevents the resins naturally found in woods being dissolved by the solvents present in most paints and seeping to the top surface discolouring the paint finish.
Clean all brushes well with Barrettine Methylated Spirits immediately after use. Not recommended to be used where waterbased / lighter coloured modern paints are to be used – use White Knotting.
White Knotting- 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.
