Overview

Barrettine Patent Knotting is a high grade knotting solution, perfect for all types of wood. It effectively seals knots in wood and resinous timber in preparation for priming and painting. It blocks naturally-forming resins found in wood from being dissolved by the solvents in paints and seeping to the surface. This then discolours the paint finish.

Please note: Not recommended for use with water-based or lighter coloured modern paints. For these instances, we suggest Barrettine White Knotting solution.
