Patent Knotting

Knotting is used for sealing the natural knots in timber prior to painting. Timber knots exude resin over the years and if not treated prior to painting they will cause the paint to discolour and crack. Patent Knotting is the most widely used.

Select surface and finish for calculation.


Patent Knotting is a heavier version of Button Polish and has a translucent, slightly brown appearance in the liquid form. The colour makes it easy to see on the timber surface which helps in seeing which knots have been treated. When dry it produces a medium brown semitransparent film.

Product Information

Knotting may be applied to both old and new timber. (Even very old timber can continue to exude sap). Knotting will hold back most natural timber resins (except the most aggressive ones).


Application is by brush.

Apply two coats of knotting allowing 2 – 3 hours between applications.

For best results leave at least overnight before applying a coat of paint primer.
