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 Methylated Spirits
immediately after use. Not recommended to be used where waterbased / lighter coloured modern paints are to be used – use White Knotting.
