The film-forming resins in Patent Knotting are unaffected by natural tree sap as well as being insoluble in hydrocarbon solvents such as White Spirit, which are normally used in traditional alkyl-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 knots. Touch dry in 5-10 minutes and can be re-coated after 30 minutes under normal conditions.
