This no fuss wet rot wood hardener from Ronseal gives interior and exterior wood a new lease of life. Harden wet wood and stop nasty rot from spreading, whether it's your garden furniture or a water damaged window frame. The fluid seeps deep into the wood and sets rock hard, which reinforces decaying parts and provides a solid base for filling.
The hardener dries quickly with a clear finish, and the lid doubles up as a container too, so everything you need is right here. A little goes a long way and one tin should see you through plenty of jobs around the house.
