Mylands Patent Knotting is a fast drying shellac used for sealing the natural knots in timber prior to painting. Timber knots exude resin over the years and if not treated prior to painting they will cause the paint to discolour and crack. Mylands Patent Knotting dries to a pale golden brown colour and is the most widely used. Where a white or pale colour is to be applied, use Mylands White Knotting instead. Prepare knots before use by scraping excess sap and residue from the surface, then degreasing using methylated spirits. Apply two coats of Mylands Patent knotting making sure to coat at least 5mm outside of the areas affected.
