Prepare timber surfaces the professional way with Bartoline Patent Knotting 500ml — a quick-drying, alcohol-based lacquer designed to seal knots and resinous areas in bare wood before painting, waxing, or polishing. This traditional preparation solution forms a tough, protective film that prevents natural sap and resins from bleeding through your finish, ensuring a smooth and long-lasting result.
The film-forming resins used in this formula are resistant to natural tree sap and insoluble in hydrocarbon solvents like White Spirit, which are commonly found in primers and decorative coatings. This makes Bartoline Patent Knotting especially effective on softwoods such as pine, where knots can otherwise cause staining or paint defects.
Fast-drying and reliable, it’s touch dry in just 5–10 minutes and ready for re-coating after around 30 minutes under normal conditions — saving valuable time on preparation.
