About Barrettine Patent Knotting 

Barrettine Patent Knotting is Shellac resin formulation applied over knots and resinous areas in timber such as spruce and pine.

Seals resin from knots and soluble extractives in the wood from discolouring the paint surface.

  • Very quick drying.
  • Can be applied to interior and exterior woodwork.
  • Ideal for timber cladding and softwood gates and doors.
  • If planning to apply water based primers, topcoats or light shades of semi-transparent wood lacquers, Barrettine White Knotting should be used in place of Patent Knotting.
  • Apply 1-2 coats by brush over knots and resinous areas.

Application

Ensure the area to be treated is clean dry and clear of any material that could interfere with the adhesion of the Knotting and subsequent coating.

Remove surface resin carefully with a sharp blade and clean the area with methylated spirit.

If the knot is highly active, a more permanent solution may be to remove the knot by drilling, filling with a good quality wood filler.

Apply a thin film of Knotting over the resinous area and allow to dry. A second thin coat may be required.

Do not thin.

Cleaning 

Clean equipment  with methylated spirit or acetone after use.
