Blackfriar Patent Knotting makes painting knotty and resinous areas easy. It’s made from pure shellac and methylated spirit and is ideal for new wood or wood stripped or burnt-off prior to priming but is not suitable for use with translucent coatings due to its dark orange colour.


Ensure surface is clean, dry and dust free. Remove any excess resin from knots by scraping then cleaning with methylated spirit.


Ensure the product is thoroughly shaken prior to use. Apply evenly using a soft brush. Overlap the knot or resinous area by at least 12mm. Apply a minimum of 2 coats, allowing to fully dry between coats.


Not required.


Not to be used as a finishing coat. Not suitable for use under clear coatings. If knots exude excess resin we recommend that they are completely removed and made good with sound timber and wood filler or a wood stopper.

Drying Time

Touch dry in 15 - 30 minutes. Recoat after 1 hour. Drying times are based on an ambient temperature of 20°C and 50% relative humidity. Lower temperatures or higher humidity will prolong the drying and overcoating times.

Clean Up

Remove as much product as possible from application equipment before washing with methylated spirit. Do not empty into drains or water courses. Some local authorities have special facilities for the disposal of waste coatings.


Store in a dry, safe place. Do not store in environments where extreme temperatures may occur. Keep within 5-30°C. Do not store in direct sunlight.
