Rustins White Knotting is a premium solution designed for sealing knots, resinous, and creosoted timber. Made with bleached shellac, it prevents the bleeding of resin through paint films, keeping your wood finishes clean and vibrant. The product is ideal for use on bare wood, and once applied, it dries quickly to create a solid base for priming and painting. Rustins White Knotting is suitable for both interior and exterior use and ensures that your paint job remains free from discoloration caused by resinous knots. Simply apply liberally to the affected areas and allow the product to dry before priming.
