Questions in relation to OrganoWood®-technology work?
- How does the OrganoWood®-technology work?
Answer: OrganoWood's patented technology has been developed and inspired by the natural fossilization process whereby organic materials such as wood are being transformed into fossils. The fssilization process whereby organic materials such as wood are being transformed into fossils. The fossilization occurs primarily on the surface of the wood encapsulation the wood fibers making them inaccessible for rot fungus. Hence, the fungi do not die as in the case of usin traditional wood preservatives containing biocides. Instead, new physical barriers are created rendering it impossible for fungi to eat he fibers.
- What are the benefits of OrganoWood®-modified timber?
Answer: In traditional timber impregnation methods biocides are used in order to kill the rot fungi and other timber destructive organisms. OrganoWood® technology uses no substances classified as hazardous or harmful, but only natural minerals and fruit substances. Our products are eco-classified and we have the highest eco-class in the Swedish Byggvarubedömningen and Sunda hus. In addition, the timber turns silver gray with time and had considreably less splinters than larch.
- Test results of OrganoWood® - modified timber?
Answer: Our timber has been put through its paces in a number of independent tests carried out by SP – Technical Research Institute of Sweden. Tests include inter alia EN 113 (rot test) and in this test OrganoWood®-modified timber received the highest durability class (EN 350-1) of 1 against broun rot. Weather resistance has been tested in the leaching test of EN 84.
- What raw materials are used in OrganoWood® - modified timber?
Answer: OrganoWood®-modified timber is made from figh-quality Swedish pine.
- How should the timber be maintained?
Answer: It is advisable that to apply OrganoWood®- 02 Repellent on OrganoWood®-modified timber once it has been fitted for the first time. This treatment can then be carried out with 2-3 year intervals. In between, the decking may require to be annually washed. If the wood decking is not maintained, it risks drying out if it is mainly exposed to extreme sun conditions. A condition that may occur is increased splitting and increased loss of surface wood fibers. For OrganoWood®-modified timber Plus no additional surface treatment is necessary since this wood has been impregnated with the OrganoWood®- 02 Repellent at the factory and will only require an annual surface wash.
- Can I use paints on my OrganoWood®-modified timber?
Answer: The modified timber has been fossilized and hence the surface is much harder then on traditional untreated trimber. Thus, it is more difficult for normal paints to penetrate the surface resulting in a poorer binding between the wood fibers and the paint. Therefore we do not recommend the use of conventional poaints in connection with OrganoWood®-modified timber. We are currently in the final stages with Nordic paint manufacturers of developing eco-paints particularly suitable for OrganoWood®-modified timber.
- How does OrganoWood® - modified timber age ?
Answer: The modified timber will age as normal timber and will become silver grey over time. How fast this greyness process takes may vary greatly where it has been placed, facing which direction and how exposed it is directly to the weather. Generally speaking the sapwood will become grey faster than the heartwood due its increased natural absorption of moist and water. In order to enjoy a more even greyness process and decrease the risk of surface fiber loss it is recommendable to treat the timber with OrganoWood 02 Repellent that decreases the absorption of moist and water in the sapwood thus smoothing the difference between the sap- and hearwood. This effect can be seen in the OrganoWood®-modified timber Plus that has been impregnated with the OrganoWood 02 Repellent already at the factory. To see the aging process of OrganoWood®-modified timber please see the attached slideshow.
- My timber shows signs of excess surface fiber loss - what is it?
Answer: A phenomenon that may occur on aging wood surfaces is the loss of excess surface wood fibers. This phenomenon arises when the sun UV-radiation is wearing down lignin that keeps the wood fibers bonded to each other and may occur faster on timber exposed to very strong sunshine. This will not diminish the wood's protection against rot, as it is only the top layer of the wood fiber that becomes detached from the wood, but it may be less appealing esthetically. For additional information, regarding surface fiber loss visit the following webpage. The excess fiber loss is easy to remedy – simply take a coarse brush and brush the affected areas in dry conditions and the excess fiber loss will come off.
Questions regarding OrganoWood's surface wood protection?
- Which species of wood benefit from OrganoWood wood protection?
Answer: The OrganoWood surface treatment products (OrganoWood 01 Protection and OrganoWood 02 Repellent) are particularly suitable for species of wood (pine, spruce, larch and regular pressure impregnated timber) that require an improved surface treatment. Applications include among others wooden constructions that are exposed to tough weather conditions like fences, wooden decks and internal installations in humid and moist conditions. For a complete list of different species of wood that benefit from OrganoWood surface products click on the link.
- Can I use OrganoWood 02 Repellent as decking oil?
Answer: OrganoWood®-Repellent is very effective decking oil. Can be used on regular pressure impregnated timber giving the treated timber highly effective water repellence and decreases the risk of surface mold and other surface fouling.
- Can I use paints on my OrganoWood treated timber?
Answer: Timber that has been treated with OrganoWood products becomes slightly fossilized and has a deser structure on the timber's surface that protects the timber. Hence, it is more difficult for normal paints to penetrate the surface resulting in a poorer binding between the wood fibers and the paint. Therfore we do not recommend the use of conventional paints in connection with OrganoWood®-modified timber.
- How long does the surface treatment of OrganoWood protection last?
Answer: If the untreated timber is treated according to the recommendations (one coat with OrganoWood 01 Protection followed by two coats of OrganoWood 02 Repellent) the protection will last up to five years.
