Wood Hardener



The wood hardener reinforces, hardens, and seals dead wood fibers in bonsai, stopping the decay and protecting against pests. It dries quickly, it's transparent and colorless.

The wood hardener - plastic dissolved in acetone - is applied with a brush to the dry, clean wood. The liquid penetrates the wood, the acetone contained in it evaporates and the plastic hardens the wood.
When using bleaching agents (Jin liquid), the wood should first be treated with the bleaching agent and then sealed with the wood hardener.

Two-time application is sufficient. We recommend annual use.
Please note the usual precautions for acetone.
