Outside wood has 2 primary opponents: UV (ultraviolet rays from sunlight) and humidity. The first causes a kind of superficial melt – like on our skin, leading to small fractures as well as greying. Nothing dramatic, the damage is generally visual, and also the wood is not affected comprehensive. Moveable Office Furniture Open Office Plan
Moisture postures much more serious troubles: if rainwater does not run or does not vaporize swiftly, if the timber continues to be in contact with the ground or if the dampness can rise by capillary action, the wetness content of the wood will permit the installation of lignivorous fungis that are forerunners to rot and support assaults by wood-eating pests. Can chemical preservative therapies be prevented?
Durable Variety, without Sapwood
Some normally long lasting species from our areas can be utilized without treatment when the timber is laid up and down (risk course 3) as well as enables good water drain (cladding, windows, shutters): particularly Douglas, larch, chestnut, oak, as well as cicada. Just the last 3 varieties are advised when the timber is laid horizontally (balcony or balcony boards) or touching the ground (threat course 4). These woods should also be selected and also cut in such a way as to get rid of the sapwood, the outer part of the trunk rich in sugars, which draws in wood-eating insects.

What Are the Advantages of Safeguarding Your Wood?
Embellishes and also Shields
Past maintaining the aesthetic aspect over time, using a timber oil or a saturator in the defense of wood will certainly revive its initial shade and also boost the grain of the timber while keeping its natural appearance.
Stabilizes the Wood
Fueling oil a wood permits improving its dimensional stability durably, thus reducing the phenomena of deformation (tiling, swelling, and shrinkage), cracking, or surface splitting.
Natural and also Ecological
Selecting an “Oleobois” safety oil indicates choosing a healthy and balanced and environmentally friendly solution; the composition excludes fungicides, turpentine, and any type of petroleum derivatives frequently utilized (paraffin, white spirit, …).
Easy as well as Economical Maintenance
Upkeep is simple since when fueled oil; wood does not require to be removed or sanded before restoration: a cleansing with black soap followed by a basic re-oiled surface suffices. Moveable Office Furniture Open Office Plan
Greying of The Timber
What Is Timber Graying?
Wood is a material nearly comprised of polysaccharides (cellulose and also hemicelluloses) as well as lignins that will be weakened under ultraviolet photons’ activity. This photodegradation of the lignins, which is additionally highlighted in the presence of water, is responsible for the development of the shade of the wood. Greying is observed on the timber utilized outdoors without any physical protection and also UV protection. This sensation triggers a change in the original shade of the raw timber with time, which tends to end up being grey.
What Are the Consequences of Greying?
Greying or graying, which is a very surface sensation, only affects the wooden structure’s aesthetic appeals. It does not show a structural change and also does not affect the solidity of the product. The appearance of this sensation is restricted to the surface area of the timber. The loss of structural toughness (which can go as far as the spoil of the product) is, for its part, as a result of assaults of biological beginning that impact the timber in its mass.
Is it feasible to prevent the greying of the timber without preserving it?
NO – Without finishing products as well as without maintenance, it would certainly be illusory to declare to be able to prevent the wood from greying.
Will the application of a finish protect against the timber from transforming gray?
YES – If this application is made routinely, it is possible to avoid this sensation. The hydrophobic nature of the oil strongly limits the wood’s fondness for water as well as consequently postpones its action. Moveable Office Furniture Open Office Plan
Rectified and Thermo-Oiled Wood
A number of current processes have made it feasible to boost the resilience and also dimensional security of other varieties considerably: these are high-temperature warm therapies (210 to 250 ° C )in numerous phases, executed in unique furnaces, either under an inert ambience with nitrogen (remedied wood) or with water vapor injections (Finnish heat-treated lumber). The wood handles a gorgeous brownish shade and also comes to be hydrophobic and also really resistant to fungal or insect assaults. Nonetheless, the heat weakens these timbers a little, which can not be utilized for architectural functions (generally in exterior siding, parquet, as well as terrace boards).
The supposed homeothermic process does not have this drawback: the timber is just warmed up to 130 ° C, with an immersion in a combination based upon linseed oil as well as vegetable oil derivatives, which enables a deep impregnation. This likewise guarantees a much longer resistance to greying and does not need regular maintenance. The process makers have actually begun to market it in France: 3 makers in the wood sector have already bought it, as well as others are in the pipe. The recent Wood-Protect procedure patented by Lapeyre as well as INRA-INPT in Toulouse is of the same type, with impregnation by autoclave and then by saturating at 140 ° C in a blend of vegetable oil derivatives and acetic acid.

High-temperature therapies make the wood completely water-proof and also fungus immune.
The timber is given a temperature between 210 ° C and 250 ° C in unique stoves. It then changes color to become darker. The main negative aspect is that it sheds its stamina. It can after that only be made use of for cladding or floor covering.
Oleothermy is a treatment that includes 3 stages: home heating to 130 ° C in a rapeseed oil bath, cooling in a linseed oil bath, and also drying out. Considering that the heating temperature level is lower than the previous method, the wood is much less breakable.
Researches have actually revealed that homeothermic home heating is useful when done after boron therapy. Boron has anti-inflammatory residential or commercial properties. The trouble is that it is not resistant to washing. Hence, the homeothermic makes it possible to deal with the molecule as well as make the timber much more resistant to flames, water, as well as shocks. To find out more about this method, right here is a doctoral thesis that was done on the topic.
Oils, Stains, as well as Paints
The resilience of particular species such as oak and chestnut is mostly because of their high tannin content. These are gradually washed out by rainwater, which is a little acidic. Like various other types, oak as well as chestnut, consequently, call for surface defense. Linseed oil with a little turpentine included – to be used in heat (it penetrates far better) – is traditional as well as low-cost defense, water-repellent, and delays greying.
Organic timber stains, which are colored yet reveal the timber grain, give far better security versus UV rays thanks to the pigments they have. They ought to be renewed every 3 to 5 years for the south facades as well as every 8 to 10 years for the north facades. Unlike paints, they do not need sanding before revival (a brush stroke is enough to get rid of the pigment dust). When it comes to natural lacquer paints, they give even more resilient defense considering that they include fillers (specifically chalk) that create an entire screen against UV rays. It’s a bit like sun creams; the safety depends on the display’s high quality and the exposure. Moveable Office Furniture Open Office Plan
To improve the longevity of outside wood normally, go with a discolor, for instance, a mixture of linseed oil as well as turpentine. Some readily available wood spots are tinted and give small UV protection. The advantage of this method is that no sanding is called for.
For also much better defense, use natural lacquer paint. It will certainly give ideal protection versus ultraviolet rays– prefer microporous paints including chalk fillers to allow the timber take a breath.
Safeguarding exterior timber normally can be performed with a protective tarnish or warm treatment. The choice of method depends upon the qualities that you desire to customize. If particular wood types can be used without security, they have to be discolored after a specific duration since the safety tannins will have vanished. If you do refrain this, you will certainly have to have an expert dampness treatment.
Shielding Timber from Water
Shielding wood from water is a necessary function of an exterior finish before any type of attractive element. It is advised to conserve the material with paint, varnish, discolor, saturator, or oil. Certainly, it is essential to achieve a real barrier result, which need to be waterproof if the timber is not to weaken also promptly.
This makes it feasible to preserve all-natural, solid, raw, or veneered wood virtually over time. It is shielded to maintain for years when faced with the various weather aggressiveness encountered. It is durably protected from humidity, rain, bad climate, light, sun, and also ultraviolet rays, making it age too soon. Moveable Office Furniture Open Office Plan
Continue To Be Normally Permeable to Wetness
Continue to be wetness permeableStaying normally absorptive to smoke is extremely essential. Wood is composed of plant fibers that have a superb fondness with water. It is, for that reason, a breakable material that remains quickly absorptive to water. It continues to be particularly sensitive to numerous liquids that penetrate it.
Timber absorbs extremely quickly the moisture that is present in the ambient environment. It takes in water before naturally releasing it because it is a hygroscopic material. It remains in constant equilibrium with its environment, whatever the moisture web content.
These different moisture variants go to the origin of the typical dimensional transformations of wood. They have the effect of causing deformations that can often be considerable. It works by swelling if the air is too humid. It diminishes when the ambience becomes drier.
Rain, showers, thunderstorms, as well as other poor climate that touch with the wood can create the look of unpleasant stains, streaks, drips, as well as halos. Wetness, seepage, condensation, and also water vapor are also responsible for the early aging of wood throughout the years. Moveable Office Furniture Open Office Plan
Do Not Prevent Exchanges with The Outdoors.
Do not protect against exchanges with the outside not protect against communications with the outside; it should be appreciated. When you intend to safeguard the timber, a water-repellent product should be applied to stay clear of water from permeating it. It has to be made certain that it is not fertilized by moisture if it is to last over the long-term.
A wood therapy item can only be completely suitable if it respects the various dampness exchanges. The timber must have the ability to continue to control itself with its atmosphere. It is necessary to make sure that the movie stays sufficiently micro-porous to guarantee an excellent exchange effectiveness.
On the other hand, impermeability and water rigidity must not be puzzled, which are very various ideas. Waterproofing should be restricted when it comes to wood defense. Making a timber totally watertight might create the material to rot in the long term.
Gas exchange, which manages the moisture material in the timber’s pores, need to never ever be stopped. A timber paint need to allow the substratum to take a breath without ever stopping the inner emptying to the exterior. It should just protect against water from penetrating the heart of the timber, not to modify or weaken it.
Selecting a Right Wood Treatment Item
Selecting a timber treatment choosing the best timber therapy product is necessary to secure wood effectively with time. There are various sorts of items that are capable of efficiently protecting this material. One can make use of a product that passes through deeply, such as oil, impregnation, or saturator.
A penetrating treatment provides much more efficient protection than an item that deposits a film on the surface, such as paint, varnish, or sealant, for example. While a film-forming item may appear valuable originally, this is not always the case in the lengthy term.
They can finish up breaking, flaking, breaking, or peeling off over the years. Infiltration, water, or moisture penetrates the material, which ends up being improperly insulated. It is after that important to sand or strip the surface area of the timber to bare it once again to be protected.
Silicones are widely utilized in wood waterproofing products. These damaging materials must be stayed clear of in the same way as petroleum solvents, which are still existing in numerous items. They are not harmless to the individual, the setting, or nature. It is better to choose a bio-sourced item of plant origin that follows this natural product.

Keep On A Regular Basis for Adequate Security.
Maintain permanently protection maintain consistently for a sufficient protection, stays a procedure that must not be failed to remember to carry out. No matter the kind of waterproofing selected to protect the timber, it is required to maintain it frequently so that the defense continues to be sufficiently effective in time.
Tiresome prep work, sanding, gritting, or removing of the surface can be stayed clear of utilizing an oil, saturator, or impregnation. They have the particularity of protecting the product throughout its mass without developing a film on the surface that can exfoliate afterward.
A waterproofing representative’s function is to safeguard the timber from spots, marks, rings, and day-to-day damage. It is normally related to an anti UV agent that will avoid the wood from becoming as well grey in the future. It therefore restricts the phenomenon of swelling or contraction.
A non-film-forming water repellent has numerous benefits for maintaining a wooden surface area. It is really effective against poor climate thanks to an obstacle effect. It continues to be extremely effective in nurturing the timber in all its depth to the product’s actual heart. It likewise safeguards the assistance from light, sunlight, as well as ultraviolet rays.
