Exterior wood has 2 main adversaries: UV (ultraviolet rays from sunshine) and humidity. The first causes a sort of surface burn – like on our skin, resulting in tiny cracks as well as greying. Absolutely nothing remarkable, the damage is mostly aesthetic, as well as the wood is not affected detailed. Room Furniture Floor Plan Layout Jpegs
Wetness postures far more severe issues: if rain does not run or does not evaporate swiftly, if the wood continues to be in contact with the ground or if the dampness can increase by capillary action, the dampness content of the wood will allow the installment of lignivorous fungi that are forerunners to rot and also support assaults by wood-eating bugs. Can chemical preservative treatments be stayed clear of?
Sturdy Types, without Sapwood
Some normally resilient varieties from our areas can be used without therapy when the timber is laid vertically (danger class 3) and permits good water drainage (cladding, home windows, shutters): particularly Douglas, larch, chestnut, oak, and also cicada. Only the last three types are advised when the wood is laid flat (terrace or terrace boards) or in contact with the ground (risk class 4). These woods need to also be picked and also cut in such a means regarding get rid of the sapwood, the outer part of the trunk rich in sugars, which brings in wood-eating insects.

What Are the Benefits of Shielding Your Timber?
Embellishes and Protects
Beyond keeping the visual facet gradually, making use of a wood oil or a saturator in the security of wood will certainly revive its original shade as well as boost the grain of the timber while maintaining its all-natural appearance.
Supports the Wood
Fueling oil a timber allows boosting its dimensional stability durably, therefore decreasing the sensations of deformation (tiling, swelling, and also shrinkage), fracturing, or surface splitting.
Natural and Ecological
Choosing an “Oleobois” safety oil implies choosing a healthy and balanced as well as environmentally friendly option; the composition excludes fungicides, turpentine, as well as any type of petroleum derivatives frequently used (paraffin, white spirit, …).
Easy and Economical Upkeep
Upkeep is easy because when oiled; timber does not require to be stripped or sanded prior to renovation: a cleaning with black soap complied with by a simple re-oiled surface area suffices. Room Furniture Floor Plan Layout Jpegs
Greying of The Wood
What Is Wood Graying?
Timber is a material almost composed of polysaccharides (cellulose and hemicelluloses) and lignins that will be broken down under ultraviolet photons’ activity. This photodegradation of the lignins, which is likewise accentuated in the existence of water, is in charge of the development of the shade of the wood. Greying is observed on the hardwood made use of outdoors without any physical defense as well as UV protection. This sensation creates a modification in the initial shade of the raw timber with time, which tends to end up being grey.
What Are the Repercussions of Greying?
Greying or graying, which is a really shallow sensation, just affects the wooden structure’s appearances. It does not show a structural change and does not affect the strength of the product. The look of this phenomenon is limited to the surface of the wood. The loss of structural toughness (which can go as far as the mess up of the product) is, for its part, as a result of strikes of organic origin that affect the wood in its mass.
Is it possible to stay clear of the greying of the timber without keeping it?
NO – Without ending up items as well as without maintenance, it would be imaginary to claim to be able to prevent the timber from greying.
Will the application of a surface prevent the timber from turning grey?
YES – If this application is made regularly, it is possible to avoid this phenomenon. The hydrophobic nature of the oil strongly restricts the timber’s fondness for water as well as therefore postpones its action. Room Furniture Floor Plan Layout Jpegs
Corrected and also Thermo-Oiled Timber
Several recent processes have actually made it feasible to boost the durability and also dimensional stability of various other species dramatically: these are high-temperature heat therapies (210 to 250 ° C )in several phases, accomplished in unique heaters, either under an inert ambience with nitrogen (rectified timber) or with water vapor injections (Finnish heat-treated lumber). The timber handles a gorgeous brownish shade as well as becomes hydrophobic as well as really resistant to fungal or insect strikes. The high temperature deteriorates these timbers a little, which can not be utilized for architectural objectives (mostly in house siding, parquet, as well as balcony boards).
The so-called homeothermic procedure does not have this negative aspect: the wood is only heated up to 130 ° C, with an immersion in a mixture based on linseed oil and vegetable oil by-products, which enables a deep impregnation. This likewise guarantees a much longer resistance to greying and also does not need routine upkeep. The procedure designers have begun to market it in France: 3 producers in the wood sector have actually already bought it, as well as others remain in the pipeline. The current Wood-Protect procedure patented by Lapeyre and INRA-INPT in Toulouse is of the same kind, with impregnation by autoclave and afterwards by saturating at 140 ° C in a mix of vegetable oil derivatives and also acetic acid.

High-temperature treatments make the timber wholly water resistant as well as fungus immune.
The wood is brought to a temperature in between 210 ° C and also 250 ° C in special ovens. It then transforms color to become darker. The major negative aspect is that it sheds its strength. It can after that just be utilized for cladding or flooring.
Oleothermy is a therapy that contains 3 phases: home heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bathroom, as well as drying. Given that the home heating temperature level is lower than the previous method, the timber is less weak.
Researches have revealed that homeothermic home heating is valuable when done after boron treatment. Boron has anti-inflammatory homes. The trouble is that it is not immune to washing. Therefore, the homeothermic makes it feasible to repair the particle and make the wood a lot more immune to flames, water, and also shocks. To find out more about this technique, right here is a doctoral thesis that was done on the subject.
Oils, Spots, and Paints
The longevity of specific varieties such as oak and chestnut is mainly as a result of their high tannin material. These are slowly washed out by rain, which is somewhat acidic. Like other species, oak and chestnut, consequently, require surface area defense. Linseed oil with a little turpentine added – to be used in hot weather (it permeates much better) – is traditional and also economical security, water-repellent, and hold-ups greying.
Organic timber stains, which are tinted yet reveal the timber grain, supply much better protection against UV rays thanks to the pigments they consist of. They should be renewed every 3 to 5 years for the south facades and also every 8 to 10 years for the north facades. Unlike paints, they do not require sanding before revival (a brush stroke is enough to eliminate the pigment dust). When it comes to natural lacquer paints, they supply more long lasting security because they have fillers (especially chalk) that create a whole screen against UV rays. It’s a bit like sun creams; the safety and security depends upon the screen’s top quality and also the exposure. Room Furniture Floor Plan Layout Jpegs
Surface area Defense
To enhance the toughness of outdoor timber normally, opt for a discolor, for instance, a blend of linseed oil and turpentine. Some commercially offered timber stains are colored as well as give small UV protection. The advantage of this technique is that no sanding is required.
For also far better defense, use natural lacquer paint. It will give optimal defense versus ultraviolet rays– prefer microporous paints having chalk fillers to let the timber breathe.
Safeguarding exterior timber naturally can be finished with a safety tarnish or warmth treatment. The option of technique depends upon the features that you desire to customize. If particular timber types can be made use of without protection, they need to be discolored after a certain period because the protective tannins will certainly have vanished. If you do not do this, you will certainly have to have a professional wetness therapy.
Safeguarding Wood from Water
Shielding timber from water is a crucial feature of an outside finish prior to any ornamental element. It is suggested to save the product with paint, varnish, discolor, saturator, or oil. Without a doubt, it is essential to achieve an actual obstacle result, which have to be waterproof if the wood is not to wear away as well rapidly.
This makes it possible to protect all-natural, solid, raw, or veneered timber basically over time. It is protected to keep for many years in the face of the numerous weather aggressiveness came across. It is durably maintained from moisture, rain, poor weather condition, light, sun, and also ultraviolet rays, making it age too soon. Room Furniture Floor Plan Layout Jpegs
Continue To Be Naturally Absorptive to Wetness
Continue to be moisture permeableStaying normally permeable to smoke is very important. Timber is composed of plant fibers that have an exceptional fondness with water. It is, as a result, a breakable material that continues to be conveniently permeable to water. It stays especially sensitive to numerous fluids that permeate it.
Timber takes in very quickly the moisture that exists in the ambient atmosphere. It absorbs water before normally releasing it due to the fact that it is a hygroscopic material. It continues to be in constant balance with its environment, whatever the wetness content.
These various humidity variants are at the beginning of the usual dimensional changes of wood. They have the impact of creating contortions that can in some cases be considerable. It functions by swelling if the air is as well moist. It diminishes when the ambience comes to be drier.
Rain, showers, thunderstorms, and other poor weather that touch with the timber can cause the appearance of unsightly spots, streaks, drips, and also halos. Moisture, infiltration, condensation, as well as water vapor are additionally in charge of the early aging of wood for many years. Room Furniture Floor Plan Layout Jpegs
Do Not Protect against Exchanges with The Outside World.
Do not protect against exchanges with the outdoors not protect against interactions with the outside; it needs to be valued. When you intend to protect the wood, a water-repellent product has to be put on prevent water from penetrating it. It should be guaranteed that it is not impregnated by wetness if it is to last over the long term.
A timber therapy product can only be flawlessly ideal if it respects the various wetness exchanges. The timber should be able to continue to regulate itself with its environment. It is essential to make certain that the movie stays completely micro-porous to ensure a good exchange efficiency.
On the other hand, impermeability and also water tightness should not be confused, which are very different concepts. Waterproofing must be restricted in the case of wood defense. Making a wood totally watertight might trigger the material to rot in the long-term.
Gas exchange, which manages the dampness material in the wood’s pores, must never ever be stopped. A timber paint have to allow the substratum to breathe without ever before quiting the internal emptying to the outside. It has to just prevent water from penetrating the heart of the wood, not to change or weaken it.
Selecting a Right Timber Treatment Item
Picking a wood treatment choosing the ideal wood therapy item is essential to protect wood effectively in time. There are various kinds of items that can properly maintaining this material. One can make use of a product that penetrates deeply, such as oil, impregnation, or saturator.
A passing through treatment offers a lot more efficient security than a product that deposits a movie on the surface, such as paint, varnish, or sealer, for instance. Undoubtedly, while a film-forming item might appear beneficial originally, this is not always the case in the long term.
They can end up fracturing, flaking, cracking, or peeling off over the years. Infiltration, water, or moisture penetrates the product, which ends up being inadequately shielded. It is then essential to sand or strip the surface of the wood to bare it once more to be maintained.
Silicones are extensively used in timber waterproofing products. These harmful materials need to be prevented in the same way as petroleum solvents, which are still present in several products. They are not harmless to the user, the setting, or nature. It is much better to choose a bio-sourced item of plant beginning that is consistent with this all-natural material.

Preserve Frequently for Adequate Security.
Preserve for good defense keep consistently for an ample defense, continues to be an operation that should not be forgotten to do. Regardless of the sort of waterproofing selected to preserve the wood, it is necessary to maintain it routinely to make sure that the security remains adequately efficient gradually.
Tedious prep work, fining sand, gritting, or stripping of the surface can be avoided utilizing an oil, saturator, or impregnation. They have the particularity of safeguarding the product throughout its mass without creating a movie on the surface that can flake off afterward.
A waterproofing agent’s feature is to shield the timber from stains, marks, rings, and everyday deterioration. It is normally connected with an anti UV representative that will avoid the wood from ending up being also grey in the future. It therefore restricts the phenomenon of swelling or shrinking.
A non-film-forming water repellent has many benefits for maintaining a wooden surface. It is really efficient versus negative weather condition thanks to an obstacle impact. Additionally, it remains very reliable in nurturing the wood in all its deepness to the material’s actual heart. It also secures the assistance from light, sun, as well as ultraviolet rays.
