Wood Preservation

Wood Preservation, certain types of wood must be preserved to prevent attacks by insects/organisms or wood-destroying fungi. What is meant by preservation is inserting chemicals into the wood (pores) so that it penetrates the surface of the wood several mm thick into the flesh of the wood.

Preservation aims to increase the useful life of wood, especially wood used for building materials or for outdoor furniture.

Wood is categorized into several durable classes.

  1. Durable class I (very durable), for example: Teak wood, Sonokeling
  2. Durable class II (durable), for example: Merbau wood, Mahogany
  3. Durable class III (less durable), for example: Rubber wood, Pine
  4. Durable class IV (not durable), for example: Albasia wood
  5. Durable class V (very not durable)

With the level of durability mentioned above, only Durable Classes III, IV and V need to be preserved. For certain purposes, the sapwood of durable grades I & II also needs to be preserved.
Preserved wood will be resistant to insect attack and wood fungus even if the wood is placed outdoors.

Preservatives whose core content is in the form of powder have various types. The material is mixed with water at a certain level of mixture (see SNI-3233-1992) and the method of preservation varies.

Borax is one of the materials used to preserve wood from the vacuum method, cold immersion, hot immersion (boiled) to polishing methods.
