Barrettine Patent Knotting Solution (Knot & Resinous Timber Sealer)

The film-forming resins in knotting solution are unaffected by natural tree sap as well as being insoluble in hydrocarbon solvents such as white spirit, which are normally used in traditional alkyd based primers and decorative coatings. The insolubility and oil-resistance of this resin prevents any interaction between the paint and the softwood sap resins which remain concentrated around the knot features typically found in many common structural timbers used in doors, skirting’s, stair rails and window frames.

The net effect being that Barrettine Patent Knotting Solution enables the professional decorator to achieve the perfect finish irrespective of the knot structure and condition of the base timbers.
