Liberon Knotting helps to prevent seepage from knots in resinous woods prior to painting or varnishing. It is ideal for use before painting and helps to minimise the discolouration of paint finishes. Liberon Kotting is pale in colour and may be used with clear varnishes. It is suitable for use on all types of wood. It is touch-dry in 15 minutes, but requires an extra 2 hours before applying finishes.The LIBKP125 has a volume of 125ml.
