The TEC 250 applicator plus our TECBOND 7718/12 polyamide hot melt (KNOT-TEC System) has been specially developed for repairing knots and filling damaged wood surfaces.
For a fast and effective repair the KNOT-TEC System is the answer. Simply fill the knot hole or damaged surface with the TECBOND 7718/12 molten adhesive (available in different colours, to match the wood: amber, beige, black and cola). When the surplus glue has been removed, which can be done easily using a sharp chisel or cutting tool, you are then able to treat or paint the wood in the normal way.
