Outdoor timber has 2 major adversaries: UV (ultraviolet rays from sunshine) and humidity. The first causes a kind of shallow melt – like on our skin, leading to tiny fractures and also greying. Nothing dramatic, the damages is primarily visual, and the wood is not influenced in depth. Room Plan Upload Floor Plan Move Furniture
Dampness presents much more serious issues: if rain does not run or does not vaporize quickly, if the wood remains in contact with the ground or if the moisture can climb by capillary action, the wetness web content of the wood will certainly allow the installment of lignivorous fungi that are precursors to rot and also favor attacks by wood-eating bugs. Can chemical preservative treatments be prevented?
Durable Variety, without Sapwood
Some normally durable varieties from our regions can be used without treatment when the wood is laid vertically (threat class 3) as well as enables excellent water drainage (cladding, home windows, shutters): particularly Douglas, larch, chestnut, oak, as well as locust. Only the last three types are suggested when the wood is laid flat (terrace or balcony boards) or touching the ground (risk course 4). These woods must additionally be chosen and cut in such a method as to remove the sapwood, the outer part of the trunk rich in sugars, which attracts wood-eating insects.

What Are the Benefits of Securing Your Wood?
Embellishes as well as Protects
Past keeping the visual facet with time, using a wood oil or a saturator in the security of timber will revive its original shade and also boost the grain of the wood while maintaining its natural appearance.
Stabilizes the Wood
Oiling a wood enables boosting its dimensional security durably, therefore decreasing the sensations of contortion (tiling, swelling, as well as contraction), breaking, or surface splitting.
All-natural as well as Ecological
Picking an “Oleobois” protective oil means picking a healthy and balanced and also eco-friendly service; the composition excludes fungicides, turpentine, and any petroleum by-products often made use of (paraffin, white spirit, …).
Easy and Economical Maintenance
Maintenance is simple due to the fact that when oiled; wood does not need to be removed or sanded before renovation: a cleaning with black soap adhered to by an easy re-oiled surface area suffices. Room Plan Upload Floor Plan Move Furniture
Greying of The Wood
What Is Wood Graying?
Timber is a material virtually comprised of polysaccharides (cellulose as well as hemicelluloses) as well as lignins that will be deteriorated under ultraviolet photons’ action. This photodegradation of the lignins, which is additionally highlighted in the visibility of water, is accountable for the development of the color of the wood. Greying is observed on the hardwood used outdoors with no physical protection and also UV protection. This sensation triggers a change in the original shade of the raw timber gradually, which has a tendency to come to be gray.
What Are the Consequences of Greying?
Greying or graying, which is a really superficial phenomenon, just affects the wooden framework’s appearances. It does not indicate a structural modification as well as does not impact the solidity of the product. The look of this sensation is limited to the surface of the timber. The loss of structural resilience (which can reach the wreck of the material) is, for its component, as a result of assaults of organic origin that influence the wood in its mass.
Is it possible to prevent the greying of the wood without keeping it?
NO – Without finishing items and without maintenance, it would certainly be illusory to declare to be able to prevent the timber from greying.
Will the application of a coating prevent the timber from turning gray?
YES – If this application is made regularly, it is possible to prevent this phenomenon. The hydrophobic nature of the oil highly restricts the wood’s affinity for water as well as as a result delays its action. Room Plan Upload Floor Plan Move Furniture
Rectified as well as Thermo-Oiled Wood
Several recent processes have actually made it feasible to enhance the sturdiness and also dimensional security of various other species substantially: these are high-temperature warmth treatments (210 to 250 ° C )in several phases, executed in unique heating systems, either under an inert atmosphere with nitrogen (rectified wood) or with water vapor injections (Finnish heat-treated lumber). The timber tackles a stunning brown shade and ends up being hydrophobic as well as really resistant to fungal or insect strikes. The high temperature level compromises these timbers a little, which can not be utilized for architectural objectives (primarily in house siding, parquet, and also balcony boards).
The so-called homeothermic process does not have this negative aspect: the timber is just warmed up to 130 ° C, with an immersion in a blend based upon linseed oil as well as vegetable oil by-products, which permits a deep impregnation. This likewise guarantees a much longer resistance to greying and also does not need normal upkeep. The process developers have started to market it in France: three makers in the timber market have already bought it, and others are in the pipe. The recent Wood-Protect procedure patented by Lapeyre as well as INRA-INPT in Toulouse is of the exact same type, with impregnation by autoclave and then by soaking at 140 ° C in a combination of grease by-products as well as acetic acid.

High-temperature therapies make the timber completely water resistant as well as fungi resistant.
The timber is given a temperature level between 210 ° C as well as 250 ° C in special ovens. It then alters color to end up being darker. The major drawback is that it sheds its strength. It can then only be made use of for cladding or floor covering.
Oleothermy is a therapy that contains 3 stages: heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bathroom, as well as drying out. Given that the heating temperature is lower than the previous method, the timber is much less fragile.
Research studies have shown that homeothermic home heating is helpful when done after boron treatment. Boron has anti-inflammatory buildings. The trouble is that it is not immune to washing. Thus, the homeothermic makes it possible to take care of the molecule and also make the wood more resistant to flames, water, and also shocks. To get more information concerning this approach, below is a doctoral thesis that was done on the topic.
Oils, Spots, and also Paints
The sturdiness of certain species such as oak and also chestnut is generally as a result of their high tannin material. These are slowly cleaned out by rainwater, which is slightly acidic. Like other types, oak as well as chestnut, consequently, call for surface security. Linseed oil with a little turpentine added – to be made use of in heat (it permeates much better) – is classic and also low-cost defense, water-repellent, as well as delays greying.
Organic timber spots, which are tinted yet reveal the wood grain, offer better protection versus UV rays thanks to the pigments they have. They must be restored every 3 to 5 years for the south exteriors and also every 8 to 10 years for the north facades. Unlike paints, they do not call for sanding prior to revival (a brush stroke suffices to eliminate the pigment dirt). As for organic lacquer paints, they give more sturdy protection given that they consist of fillers (especially chalk) that develop an entire screen against UV rays. It’s a bit like sun creams; the safety depends on the display’s high quality as well as the direct exposure. Room Plan Upload Floor Plan Move Furniture
Surface area Security
To enhance the durability of outside timber normally, choose a tarnish, as an example, a mix of linseed oil and turpentine. Some commercially available timber discolorations are tinted as well as provide minor UV defense. The benefit of this method is that no sanding is required.
For also better protection, apply organic lacquer paint. It will certainly provide optimum security versus ultraviolet rays– prefer microporous paints having chalk fillers to allow the wood breathe.
Securing outside timber normally can be finished with a protective discolor or warm treatment. The choice of technique relies on the qualities that you desire to modify. If specific timber types can be made use of without defense, they must be tarnished after a particular period since the protective tannins will have vanished. If you do not do this, you will certainly have to have a professional wetness treatment.
Safeguarding Timber from Water
Safeguarding timber from water is a vital function of an outside finish before any kind of attractive element. It is advised to conserve the product with paint, varnish, stain, saturator, or oil. It is important to achieve an actual obstacle impact, which must be waterproof if the timber is not to wear away too quickly.
This makes it possible to preserve all-natural, strong, raw, or veneered wood practically in time. It is secured to keep for several years despite the various climatic hostilities came across. It is durably protected from moisture, rain, negative climate, light, sunlight, as well as ultraviolet rays, making it age prematurely. Room Plan Upload Floor Plan Move Furniture
Remain Normally Absorptive to Dampness
Stay wetness permeableStaying normally absorptive to smoke is really important. Wood is composed of plant fibers that have an exceptional affinity with water. It is, therefore, a vulnerable product that continues to be quickly permeable to water. It stays especially conscious different liquids that permeate it.
Wood absorbs very swiftly the moisture that exists in the ambient environment. It takes in water before naturally launching it since it is a hygroscopic product. It continues to be in constant stability with its setting, whatever the dampness content.
These various humidity variants go to the origin of the normal dimensional makeovers of wood. They have the effect of triggering deformations that can occasionally be substantial. It functions by swelling if the air is also moist. It shrinks when the environment comes to be drier.
Rain, showers, electrical storms, as well as various other bad weather condition that touch with the wood can trigger the look of undesirable discolorations, streaks, leaks, and halos. Wetness, seepage, condensation, as well as water vapor are also in charge of the premature aging of timber throughout the years. Room Plan Upload Floor Plan Move Furniture
Do Not Avoid Exchanges with The Outdoors.
Do not protect against exchanges with the outdoors not protect against communications with the outside; it should be appreciated. When you intend to safeguard the timber, a water-repellent product has to be related to avoid water from permeating it. It has to be guaranteed that it is not fertilized by dampness if it is to last over the long-term.
A wood treatment product can just be flawlessly suitable if it respects the different dampness exchanges. The timber needs to have the ability to remain to regulate itself with its environment. It is vital to ensure that the film stays sufficiently micro-porous to assure a good exchange performance.
On the other hand, impermeability and water rigidity should not be confused, which are really various notions. Waterproofing must be restricted when it comes to wood defense. Making a timber completely watertight might create the material to rot in the long term.
Gas exchange, which regulates the moisture web content in the timber’s pores, need to never be prevented. A wood paint have to enable the substrate to breathe without ever before stopping the inner evacuation to the outside. It should just prevent water from penetrating the heart of the timber, not to alter or degrade it.
Picking a Right Timber Treatment Item
Selecting a wood therapy picking the best wood treatment product is important to shield timber efficiently over time. There are different kinds of items that can effectively maintaining this material. One can utilize a product that penetrates deeply, such as oil, impregnation, or saturator.
A penetrating therapy supplies more reliable defense than an item that transfers a movie on the surface area, such as paint, varnish, or sealer. Indeed, while a film-forming product might appear helpful initially, this is not constantly the case in the long term.
They can finish up breaking, flaking, fracturing, or peeling off over the years. Infiltration, water, or moisture penetrates the material, which comes to be inadequately protected. It is then important to sand or strip the surface area of the timber to bare it once again to be maintained.
Silicones are commonly used in timber waterproofing products. These unsafe compounds must be avoided similarly as petroleum solvents, which are still present in many items. They are not safe to the user, the atmosphere, or nature. It is better to choose a bio-sourced item of plant origin that is consistent with this natural material.

Preserve On A Regular Basis for Adequate Defense.
Preserve forever defense keep frequently for an adequate defense, continues to be an operation that needs to not be forgotten to perform. No matter the sort of waterproofing picked to protect the wood, it is required to maintain it consistently to ensure that the defense remains completely reliable over time.
Tiresome prep work, fining sand, gritting, or removing of the surface area can be avoided utilizing an oil, saturator, or impregnation. They have the particularity of protecting the product throughout its mass without creating a film externally that can flake off later.
A waterproofing agent’s feature is to protect the timber from stains, marks, rings, and everyday deterioration. It is normally associated with an anti UV representative that will avoid the timber from becoming as well grey in the long run. It therefore restricts the sensation of swelling or shrinking.
A non-film-forming water repellent has many advantages for maintaining a wooden surface area. It is very effective versus negative weather condition thanks to a barrier effect. Likewise, it stays extremely efficient in nurturing the wood in all its depth to the material’s very heart. It likewise safeguards the assistance from light, sun, as well as ultraviolet rays.
