The wood hardener is a thin liquid which quickly penetrates residual wood fibers in soft and previously decaying timber, strengthening and binding them together.

It cures and hardenens within 24 hours, providing a sound, hard consolidated substrate which is ready for filling the next day.

Formulated using a more expensive moisture cured binder makes a great deal of sense, as the wood hardender will cure quite happily using residual dampness and moisture left in the timbers following repair work. However, do not apply directly to wet substrates.
