Teak (Tectona grandis) is a large, deciduous tree (up to 40 m (131ft) tall) and is dominant in natural, mixed hardwood forests in India, Myanmar, Laos and Thailand. The majority of commercially harvested teak is grown in plantations in Indonesia. The primary use of teak from Indonesia is in the production of outdoor teak furniture for export. Teak timber is particularly valued for its durability and water resistance, and is used for boat building, exterior construction, veneer, furniture, carving, turnings, and other small wood projects. Teak’s natural oils make it useful in exposed locations, and make the timber termite and pest resistant. It is considered to be the ‘gold standard’ for decay resistance, and its heartwood is rated as very durable being resistant to termites.
Teak is durable even when not treated with oil or varnish. Teak is a yellowish brown timber with good grain and texture. Although easily worked, it can cause severe blunting on edged tools because of the presence of silica in the wood. Teak timber has a leather-like smell when it is freshly milled. Teak’s high oil content, high tensile strength and tight grain makes it particularly suitable for outdoor furniture applications. Over time teak can mature to a silvery-grey finish, especially when exposed to sunlight.
Teak can withstand many of Mother Nature’s extreme highs and lows without cracking or warping. It’s also resistant to mold and rot. However, this doesn’t keep mildew from accumulating on the surface of your teak. The teak is protected by its own natural oils that migrate to the surface of the wood. The elements oxidize this oil, turning the wood gray and promoting the growth of mildew
If left unattended, mildew can discolor teak garden furniture, causing the wood to become darker in irregular splotches. Cleaning your teak can help remove mold and mildew before it takes hold, preventing this irregular discoloration.
Use DEVON Timber Furniture Cleaner, which is specifically designed to kill mold and mildew spores inside teak. Simply follow the directions on the bottle and the mold should be removed.
Note: All DEVON teak products comes standard with DEVON Teak shield applied so ensure you clean the teak with the DEVON cleaner before applying DEVON Teak protector so that it can absorb into the timber.
Since cleaning teak takes some time and effort, we recommend using DEVON Teak Protector or DEVON Timber Furniture Shield before weathering takes effect again.
