Outdoor timber has 2 main opponents: UV (ultraviolet rays from sunshine) and also humidity. The first causes a sort of shallow shed – like on our skin, leading to tiny fractures and greying. Absolutely nothing dramatic, the damages is mainly aesthetic, as well as the wood is not influenced extensive. Open Plan Systems Office Furniture Equip
Wetness positions a lot more extreme issues: if rain does not run or does not vaporize quickly, if the timber stays touching the ground or if the moisture can increase by capillary action, the dampness material of the wood will certainly enable the installment of lignivorous fungis that are forerunners to rot and also support assaults by wood-eating insects. Can chemical preservative therapies be stayed clear of?
Sturdy Types, without Sapwood
Some normally resilient species from our areas can be used without treatment when the wood is laid up and down (risk class 3) and permits excellent water drain (cladding, windows, shutters): particularly Douglas, larch, chestnut, oak, and cicada. Only the last 3 varieties are recommended when the wood is laid flat (balcony or terrace boards) or touching the ground (danger class 4). These timbers need to also be chosen and also cut in such a way regarding eliminate the sapwood, the peripheral part of the trunk rich in sugars, which draws in wood-eating bugs.

What Are the Advantages of Safeguarding Your Wood?
Embellishes and Secures
Beyond maintaining the aesthetic element gradually, utilizing a timber oil or a saturator in the defense of wood will restore its original color and also enhance the grain of the timber while maintaining its all-natural appearance.
Maintains the Timber
Oiling a timber allows enhancing its dimensional security durably, therefore reducing the phenomena of contortion (tiling, swelling, as well as shrinkage), cracking, or surface splitting.
Natural as well as Ecological
Picking an “Oleobois” safety oil means choosing a healthy and balanced and eco-friendly remedy; the structure leaves out fungicides, turpentine, and any oil derivatives regularly utilized (paraffin, white spirit, …).
Easy and Economical Maintenance
Maintenance is easy due to the fact that once fueled oil; wood does not need to be removed or fined sand prior to renovation: a cleaning with black soap complied with by a basic re-oiled surface area is enough. Open Plan Systems Office Furniture Equip
Greying of The Timber
What Is Timber Graying?
Wood is a material nearly comprised of polysaccharides (cellulose and hemicelluloses) as well as lignins that will be degraded under ultraviolet photons’ action. This photodegradation of the lignins, which is also accentuated in the existence of water, is accountable for the development of the shade of the wood. Greying is observed on the lumber made use of outdoors without any physical defense and also UV protection. This sensation creates a change in the original shade of the raw timber in time, which has a tendency to come to be grey.
What Are the Effects of Greying?
Greying or graying, which is a really superficial phenomenon, only impacts the wood structure’s appearances. It does not suggest an architectural modification as well as does not affect the solidity of the product. The appearance of this sensation is limited to the surface of the wood. The loss of structural durability (which can reach the destroy of the product) is, for its part, due to attacks of organic beginning that affect the timber in its mass.
Is it feasible to avoid the greying of the timber without preserving it?
NO – Without finishing items and also without maintenance, it would certainly be imaginary to assert to be able to avoid the wood from greying.
Will the application of a coating avoid the wood from transforming grey?
YES – If this application is made regularly, it is feasible to prevent this sensation. The hydrophobic nature of the oil highly limits the timber’s affinity for water and consequently postpones its action. Open Plan Systems Office Furniture Equip
Corrected and also Thermo-Oiled Wood
Several recent procedures have actually made it feasible to improve the longevity as well as dimensional security of other types considerably: these are high-temperature heat treatments (210 to 250 ° C )in several phases, accomplished in unique heaters, either under an inert environment with nitrogen (fixed wood) or with water vapor injections (Finnish heat-treated lumber). The wood handles a beautiful brownish shade and ends up being hydrophobic as well as extremely resistant to fungal or insect strikes. However, the heat deteriorates these timbers a little, which can not be made use of for structural objectives (primarily in house siding, parquet, and balcony boards).
The supposed homeothermic process does not have this disadvantage: the wood is just heated up to 130 ° C, with an immersion in a combination based upon linseed oil and also vegetable oil derivatives, which permits a deep impregnation. This likewise makes sure a longer resistance to greying as well as does not need normal maintenance. The process developers have started to market it in France: three makers in the timber sector have actually already bought it, as well as others are in the pipe. The recent Wood-Protect process patented by Lapeyre and INRA-INPT in Toulouse is of the same type, with impregnation by autoclave and afterwards by soaking at 140 ° C in a mix of vegetable oil derivatives and acetic acid.

High-temperature treatments make the timber entirely water resistant as well as fungus immune.
The timber is given a temperature level between 210 ° C and also 250 ° C in special stoves. It then transforms shade to end up being darker. The primary 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 phases: home heating to 130 ° C in a rapeseed oil bathroom, cooling down in a linseed oil bathroom, as well as drying. Because the home heating temperature is less than the previous technique, the wood is much less brittle.
Studies have actually shown that homeothermic home heating is helpful when done after boron treatment. Boron has anti-inflammatory buildings. The issue is that it is not immune to washing. Hence, the homeothermic makes it feasible to repair the molecule and make the timber a lot more immune to flames, water, and also shocks. For more information regarding this method, right here is a doctoral thesis that was done on the subject.
Oils, Discolorations, as well as Paints
The durability of certain varieties such as oak and chestnut is primarily as a result of their high tannin content. These are gradually cleaned out by rainwater, which is a little acidic. Like various other types, oak and chestnut, consequently, require surface area protection. Linseed oil with a little turpentine included – to be used in heat (it permeates better) – is classic and also cost-effective defense, water-repellent, as well as hold-ups greying.
Organic timber spots, which are tinted however show the timber grain, offer far better defense against UV rays thanks to the pigments they have. They ought to be restored 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 renewal (a brush stroke is enough to remove the pigment dust). As for organic lacquer paints, they provide even more sturdy protection given that they have fillers (particularly chalk) that create an entire screen versus UV rays. It’s a bit like sun creams; the protection depends on the display’s top quality and the direct exposure. Open Plan Systems Office Furniture Equip
To improve the durability of outside wood naturally, opt for a tarnish, for example, a blend of linseed oil and turpentine. Some readily readily available timber spots are tinted as well as give mild UV protection. The benefit of this approach is that no sanding is called for.
For even far better defense, apply natural lacquer paint. It will certainly provide optimal security versus ultraviolet rays– prefer microporous paints containing chalk fillers to let the wood take a breath.
Shielding exterior wood normally can be performed with a protective tarnish or heat treatment. The option of method depends upon the features that you wish to modify. If specific timber species can be used without protection, they should be discolored after a particular duration since the safety tannins will have disappeared. If you do refrain from doing this, you will certainly need to have a specialist wetness treatment.
Shielding Wood from Water
Protecting timber from water is a vital feature of an exterior coating prior to any kind of attractive aspect. It is advised to save the material with paint, varnish, tarnish, saturator, or oil. It is essential to attain a genuine obstacle impact, which should be waterproof if the timber is not to degrade also quickly.
This makes it feasible to preserve natural, strong, raw, or veneered timber essentially gradually. It is protected to keep for several years when faced with the various weather aggressions encountered. It is durably maintained from moisture, rain, bad weather, light, sun, and also ultraviolet rays, making it age prematurely. Open Plan Systems Office Furniture Equip
Remain Naturally Absorptive to Wetness
Stay dampness permeableStaying naturally absorptive to smoke is extremely essential. Wood is made up of plant fibers that have an outstanding fondness with water. It is, for that reason, a delicate product that stays quickly permeable to water. It continues to be particularly sensitive to different liquids that penetrate it.
Timber soaks up very promptly the moisture that is present in the ambient ambience. It soaks up water prior to naturally launching it due to the fact that it is a hygroscopic product. It remains in continuous balance with its atmosphere, whatever the dampness content.
These various moisture variants are at the origin of the common dimensional changes of wood. They have the impact of creating deformations that can occasionally be substantial. It functions by swelling if the air is too humid. It shrinks when the atmosphere becomes drier.
Rainfall, showers, electrical storms, and other negative weather that touch with the timber can cause the appearance of undesirable spots, streaks, drips, and halos. Dampness, seepage, condensation, as well as water vapor are likewise in charge of the premature aging of timber over the years. Open Plan Systems Office Furniture Equip
Do Not Stop Exchanges with The Outside World.
Do not stop exchanges with the outside not protect against interactions with the exterior; it needs to be valued. When you wish to shield the wood, a water-repellent product needs to be related to stay clear of water from penetrating it. It must be made sure that it is not impregnated by moisture if it is to last over the long term.
A timber treatment item can only be perfectly ideal if it appreciates the various moisture exchanges. The wood has to be able to continue to regulate itself with its atmosphere. It is necessary to make sure that the movie continues to be adequately micro-porous to ensure a good exchange performance.
On the other hand, impermeability and water rigidity should not be puzzled, which are very various ideas. Waterproofing has to be prohibited when it comes to wood protection. Making a timber completely watertight may cause the material to rot in the long-term.
Gas exchange, which manages the wetness web content in the wood’s pores, should never ever be prevented. A wood paint must allow the substratum to take a breath without ever stopping the internal discharge to the outside. It should just prevent water from penetrating the heart of the timber, not to alter or weaken it.
Picking a Right Timber Treatment Product
Picking a timber therapy picking the ideal timber treatment item is essential to secure timber effectively over time. There are various kinds of products that are capable of properly preserving this product. One can make use of an item that passes through deeply, such as oil, impregnation, or saturator.
A penetrating treatment offers more efficient protection than an item that transfers a film externally, such as paint, varnish, or sealer, for instance. While a film-forming item might appear useful originally, this is not always the case in the long term.
Certainly, they can end up fracturing, flaking, cracking, or peeling off for many years. Seepage, water, or humidity passes through the product, which comes to be inadequately insulated. It is then necessary to sand or strip the surface area of the wood to bare it once again to be maintained.
Silicones are commonly utilized in timber waterproofing items. These unsafe substances ought to be avoided in the same way as petroleum solvents, which are still existing in several items. They are not harmless to the user, the setting, or nature. It is far better to pick a bio-sourced item of plant beginning that is consistent with this natural product.

Preserve Consistently for Adequate Security.
Keep permanently security maintain on a regular basis for an adequate protection, remains a procedure that should not be failed to remember to perform. Regardless of the kind of waterproofing selected to protect the timber, it is needed to maintain it consistently to ensure that the defense stays adequately effective over time.
Tedious prep work, sanding, gritting, or stripping of the surface can be avoided utilizing an oil, saturator, or impregnation. They have the particularity of safeguarding the material throughout its mass without creating a film on the surface that can flake off later.
A waterproofing representative’s function is to protect the timber from spots, marks, rings, and everyday damage. It is typically connected with an anti UV representative that will certainly prevent the wood from coming to be too grey over time. It therefore limits the sensation of swelling or shrinkage.
A non-film-forming water repellent has several advantages for protecting a wooden surface. It is really effective versus negative weather thanks to a barrier effect. It stays very effective in nurturing the wood in all its deepness to the product’s very heart. It also protects the assistance from light, sunlight, as well as ultraviolet rays.
