Tanalising process:

Tanalising is a type of wood seasoning involving having wood be impregnated with 'Tanalith E'.
Tanalith E is an Eco-friendly wood preservative. It is impregnated into softwood timbers during the wood seasoning process, and the chemicals become physically fixed to the timber which leaves them unable to be removed. Tanalising however will reveal a slight green tinge in woods.

Tanalised timber does not need any treatment such as varnish, but it will subdue to weather over time and fade to a grey colour due to sun & moisture. However, the use of the preservative will still continue to be in effect.

Being Tanalised, wood is resistant to wood decay and insects wherever the timber itself to be used.

Tanalising process:



1. The Tanalising process begins with having timber placed in the treatment cylinder in which a vacuum is created within the cells of the timber.

2. The cylinder is then filled with the preservative treatment.

3. Hydraulic pressure is applied, forcing the preservative deep into timber cells. Roughly about 5mm.

4. After a set period, determined by the species of the timber currently being treated and for its planned use, the treatment solution is taken back into storage and a final vacuum extracts any excess treatment solution from the timber.

5. Low pressure inside the timber draws in the surface solution when vented to the outside atmosphere. The timber is then left for an established period for the fixation of the preservative to occur completely.
