Everbuild Lumberjack Wet Rot Wood Hardener is a highly penetrative solution of selected resins in solvent which soaks deep into the fibres of decaying wood and dries to leave the wood hard and resistant to further moisture penetration. The resin-modified wood then becomes an ideal base for repair with Lumberjack High Performance Wood Filler. The Wet Rot Wood Hardener solution is dry in six hours and is suitable for interior and exterior use providing a cost-effective alternative to replacing joinery affected by wet rot.
