250ml Patent Knotting
Shellac based patent knotting solution for sealing knots on bare timber and other resinous areas prior to the application of paints, waxes or polishes. Patent shellac knotting Solution is naturally brown in colour, shake well and apply the solution liberally to prepared bare timber, over and around the knot or resinous area with a brush. Allow to dry between coats, minimum 1 hour. Over-coated with a water-based coating system, apply the knotting solution more sparingly, and once dry, lightly abrade the surface to provide a key before over-coating. Knotting solution can really only hold back extractive staining, from knots and resinous areas of timber bleeding through the paint coating film.
