Description

Rustins Knotting prevents the tannin from knots bleeding through paint coatings, suitable for both internal and external use. A traditional shellac based product mixed with methylated spirits.

Most types of oil-based wood primers may be applied over Rustins Knotting, including knotting-compatible water-based coatings.

Preparation

The surface must be clean, bare and sanded smooth.
Clean off any excess resin using white spirit and allow to dry.
A heat gun may be used (taking care not to char the wood) to draw-out excess resin, then scrape away.
If there are cracks or holes around the knot, fill with Rustins Woodfiller, allow to dry, and sand smooth prior to applying Knotting.

Using a brush apply Knotting liberally over the knot and surrounding area.
Apply 2 coats. Do not sand after application knotting.
Allow 1 hour to dry between coats.
