500 ml Patent Knotting

• Rapidly seals knots in wood before painting and prevents them leaking resin through the finished paint causing discolouration
• Quick drying formula using natural shellac to seal the knots
• Used for darker coloured paints for lighter finishes use barrettine white knotting

Quick drying Shellac in alcohol, which is applied over knots and resinous areas in wood, to seal prior to painting. For use internally and externally. Patent Knotting prevents the resins naturally found in woods being dissolved by the solvents present in most paints and seeping to the top surface discoloring the paint finish. Clean all brushes well with barrettine methylated spirits immediately after use. Not recommended to be used where water based/lighter coloured modern paints are to be used, use white Knotting.
