Questions in relation to OrganoWood®-technology work?
- How does the OrganoWood® technology work?
Answer: The technology imitates the natural fossilisation process where organic materials such as wood are converted to fossils. During this, natural minerals such as silicon penetrate into the wood, which creates a physical barrier that keeps away wood-decay fungi.
- What are the advantages of OrganoWood® modified timber?
Answer: Biocides and heavy metals are used in traditionally pressure impregnated timber to kill the wood-decay fungi and the wood-degrading organisms. However, these substances are harmful and dangerous for the environment. The OrganoWood® technology does not use substances that are classified as harmful to health or the environment, only natural minerals and fruit substances are used. The products are environmentally classified and have received the highest recommendations from both SundaHus and Byggvarubedömningen. Furthermore, the timber turns silver grey over time and is significantly more non-stick than larch wood.
- What tests has OrganoWood® modified timber undergone?
Answer: The timber is tested by RISE (SP) – Research Institutes of Sweden in the rot protection test EN 113 and based on this has obtained durability class 1 pursuant to EN 350-1 against brown rot. Weather resistance is tested according to the leaching test EN 84.
- Which raw materials is OrganoWood® modified decking timber made of?
Answer: OrganoWood® modified decking timber is made of high quality Swedish pine.
- How should decking timber be maintained?
Answer: For OrganoWood® modified decking timber standard it is recommended that surface treatment with OrganoWood® Repellent is carried out when it is laid. This treatment should then be repeated at approximately 2-3 year intervals. In between this, the decking should be washed annually as seen fit. If the decking timber is not maintained there is a risk of it drying out especially if it is exposed in extremely sunny environments. Problems that can arise are increased crack formation and furring (“fibre fuzz”). For OrganoWood® modified decking timber Select Plus, no extra surface treatment is recommended during installation of the timber. However, it is recommended to clean and surface treat with OrganoWood® Repellent every 2-3 years or when necessary.
- Can I paint OrganoWood® modified timber?
Answer: The modified timber mineralises and then becomes significantly harder and denser than normal timber. Thus traditional paint does penetrate into the timber in the same way as normal timber. Resulting in inferior binding between the paint wood fibres. Consequently, OrganoWood modified timber should not be painted using conventional paint. We are currently working on the development of an environmental classified paint system specially designed for OrganoWood® modified panel timber.
- How does OrganoWood® modified timber age?
Answer: The timber ages as usual timber and turns silver grey over time. How quickly the timber greys depends however a great deal on how it is placed, in which direction if faces, and how it is exposed to the weather and wind. Generally, sapwood greys faster than heartwood, as the sapwood absorbs water and thus is substantially more moist than heartwood. In order to get a more even greying process and reduce the risk of furring, treatment with OrganoWood® Repellent that reduces the absorption of water in sapwood is recommended as this makes the sapwood and heartwood more similar. This effect is also achieved on OrganoWood® modified decking timber Select Plus, which is impregnated with OrganoWood® Repellent. To follow OrganoWood® modified decking timber’s aging process watch the following slideshow.
- My timber has become fuzzy with fibre, what is this?
Answer: A phenomenon that can occur on aged timber known as furring (“fibre fuzz”), where the fibres loosen from the surface of the timber. This phenomenon occurs due to the lignin that binds the fibres together is broken down by the sun’s UV radiation and this arises much faster in areas heavily exposed to sunlight. This does not destroy the timber’s protection against rot, as it is only the outer fibres that release, but it is unattractive. For more information about furring, refer to the Swedish wood’s wood guide. Easily remove fibre fuzz with a coarse brush. Brush the affected areas when the timber is dry and the excess will come off.
Questions regarding OrganoWood’s surface wood protection?
- What woods does the OrganoWood wood preservative system work on?
Answer: Use the OrganoWood wood preservative system (OrganoWood® Protection and OrganoWood® Repellent) on timber that needs improved surface protection, for example, pine, spruce, larch and pressure impregnated timber, but virtually all kinds of woods are suitable with a few exceptions. Examples of application areas are wooden structures in moderately exposed environments such a fence boards, panels, patios of pressure impregnated timber of damp indoor environments. For a complete list of woods that can be treated, please contact out experts and distributors Osmo UK.
- Can I use OrganoWood® Repellent as a decking oil?
Answer: OrganoWood® repellent works very effectively as a decking oil. It can be used on pressure impregnated decking to produce highly efficient water repellent properties and reduce the risk of mould and surface growth. The treatment also works on other woods such as larch, oak and other hardwoods.
- Can OrganoWood® treated timber be painted?
Answer: Timber treated with the OrganoWood wood preservative system mineralises and thus creates a denser structure on the timber’s surface that protects the timber. On account of the denser structure, traditional paint does penetrate into the timber in the same way as normal timber. Resulting in inferior binding between the paint wood fibres. Consequently, OrganoWood treated timber should not be painted using conventional paint. We are currently working on the development of an environmental classified paint system specially designed for OrganoWood® treated timber.
- How long does the surface treatment of untreated timber last?
Answer: If the untreated timber is treated in accordance with the recommendations (one coat of OrganoWood® protection followed by two coats of OrganoWood® Repellent.) It is time to perform maintenance with OrganoWood 02,. again when the surface starts to lose its superhydrophobic (water repellent) function. The whole surface does not always need to be maintained, maintenance can be performed gradually, e.g. walkway on a patio/terrace
