Exterior timber has 2 main enemies: UV (ultraviolet rays from sunlight) and moisture. The first causes a kind of superficial burn – like on our skin, leading to little splits as well as greying. Absolutely nothing significant, the damages is generally aesthetic, and also the wood is not influenced detailed. Plan View Furniture Vector
Wetness poses a lot more extreme troubles: if rain does not run or does not evaporate swiftly, if the timber stays in contact with the ground or if the moisture can rise by capillary action, the moisture content of the timber will certainly enable the installation of lignivorous fungis that are precursors to rot and support assaults by wood-eating bugs. Can chemical preservative therapies be prevented?
Durable Types, without Sapwood
Some naturally long lasting species from our regions can be utilized without therapy when the wood is laid up and down (danger class 3) as well as allows excellent water drainage (cladding, windows, shutters): in particular Douglas, larch, chestnut, oak, and locust. Only the last 3 varieties are recommended when the timber is laid horizontally (terrace or balcony boards) or in contact with the ground (threat course 4). These woods have to additionally be chosen and cut in such a way regarding eliminate the sapwood, the peripheral part of the trunk rich in sugars, which attracts wood-eating bugs.

What Are the Advantages of Protecting Your Timber?
Embellishes and also Shields
Beyond keeping the visual element with time, utilizing a timber oil or a saturator in the security of wood will certainly revitalize its initial shade and also improve the grain of the timber while maintaining its all-natural look.
Stabilizes the Wood
Oiling a timber permits improving its dimensional stability durably, therefore decreasing the sensations of contortion (tiling, swelling, and shrinkage), splitting, or surface area splitting.
Natural and also Ecological
Selecting an “Oleobois” safety oil means picking a healthy as well as environmentally friendly solution; the composition leaves out fungicides, turpentine, as well as any oil derivatives frequently utilized (paraffin, white spirit, …).
Easy and also Economical Upkeep
Maintenance is easy due to the fact that when oiled; timber does not require to be removed or sanded prior to improvement: a cleansing with black soap adhered to by a simple re-oiled surface area suffices. Plan View Furniture Vector
Greying of The Wood
What Is Wood Graying?
Timber is a material virtually made up of polysaccharides (cellulose and hemicelluloses) and lignins that will be deteriorated under ultraviolet photons’ action. This photodegradation of the lignins, which is additionally emphasized in the presence of water, is in charge of the advancement of the color of the wood. Greying is observed on the hardwood used outdoors with no physical defense as well as UV security. This phenomenon triggers a change in the initial shade of the raw wood over time, which often tends to come to be gray.
What Are the Effects of Greying?
Greying or graying, which is a very surface sensation, just influences the wooden framework’s aesthetics. It does not show a structural change as well as does not affect the strength of the material. The appearance of this sensation is restricted to the surface of the timber. The loss of structural durability (which can reach the wreck of the material) is, for its part, because of assaults of biological beginning that influence the wood in its mass.
Is it possible to prevent the greying of the timber without keeping it?
NO – Without finishing products as well as without maintenance, it would be illusory to claim to be able to prevent the timber from greying.
Will the application of a finish prevent the wood from turning grey?
YES – If this application is made on a regular basis, it is possible to avoid this phenomenon. The hydrophobic nature of the oil highly limits the wood’s fondness for water and as a result delays its activity. Plan View Furniture Vector
Rectified and Thermo-Oiled Wood
A number of current procedures have actually made it possible to improve the sturdiness and also dimensional stability of other varieties considerably: these are high-temperature warm therapies (210 to 250 ° C )in a number of stages, accomplished in special heaters, either under an inert atmosphere with nitrogen (remedied timber) or with water vapor injections (Finnish heat-treated lumber). The wood takes on an attractive brownish color and also becomes hydrophobic and very resistant to fungal or insect assaults. The high temperature weakens these woods a little, which can not be used for structural purposes (generally in home siding, parquet, as well as balcony boards).
The supposed homeothermic procedure does not have this disadvantage: the timber is only warmed up to 130 ° C, with an immersion in a mix based on linseed oil and also grease derivatives, which allows a deep impregnation. This likewise makes certain a longer resistance to greying and does not require normal maintenance. The process developers have actually begun to market it in France: three producers in the timber market have currently bought it, and also others remain in the pipeline. The recent Wood-Protect process patented by Lapeyre and also INRA-INPT in Toulouse is of the exact same kind, with impregnation by autoclave and then by soaking at 140 ° C in a blend of vegetable oil derivatives and also acetic acid.

High-temperature therapies make the timber completely water-proof and also fungi resistant.
The wood is offered a temperature level in between 210 ° C and also 250 ° C in special stoves. It then alters shade to become darker. The main drawback is that it loses its toughness. It can after that only be made use of for cladding or floor covering.
Oleothermy is a treatment that consists of 3 phases: home heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bath, as well as drying. Considering that the home heating temperature level is lower than the previous technique, the wood is much less brittle.
Research studies have shown that homeothermic heating is helpful when done after boron therapy. Boron has anti-inflammatory properties. The problem is that it is not immune to cleaning. Hence, the homeothermic makes it possible to take care of the molecule and make the wood much more immune to flames, water, and also shocks. For more information regarding this technique, below is a doctoral thesis that was done on the topic.
Oils, Discolorations, as well as Paints
The sturdiness of particular species such as oak as well as chestnut is generally due to their high tannin web content. Nonetheless, these are progressively rinsed by rain, which is somewhat acidic. Like other types, oak and also chestnut, therefore, call for surface area security. Linseed oil with a little turpentine included – to be utilized in heat (it permeates better) – is traditional and also cost-effective protection, water-repellent, and also delays greying.
Organic timber spots, which are colored but show the wood grain, give far better protection versus UV rays thanks to the pigments they have. Nonetheless, they ought to be restored every 3 to 5 years for the south exteriors and also every 8 to ten years for the north exteriors. Unlike paints, they do not need sanding prior to renewal (a brush stroke suffices to get rid of the pigment dirt). As for natural lacquer paints, they supply even more long lasting protection given that they have fillers (specifically chalk) that create a whole screen against UV rays. It’s a little bit like sun creams; the protection depends upon the screen’s top quality and also the direct exposure. Plan View Furniture Vector
Surface area Protection
To improve the toughness of exterior wood normally, select a discolor, for instance, a mixture of linseed oil and also turpentine. Some readily available wood spots are tinted and supply slight UV protection. The benefit of this technique is that no sanding is called for.
For also far better protection, apply natural lacquer paint. It will give ideal defense against ultraviolet rays– prefer microporous paints containing chalk fillers to let the timber breathe.
Shielding exterior timber naturally can be finished with a safety tarnish or warm therapy. The choice of technique relies on the features that you wish to customize. If specific timber species can be made use of without security, they must be discolored after a certain period since the protective tannins will certainly have vanished. If you do refrain this, you will certainly need to have an expert wetness therapy.
Shielding Timber from Water
Protecting timber from water is a necessary feature of an outside surface before any kind of attractive facet. It is suggested to conserve the product with paint, varnish, discolor, saturator, or oil. Undoubtedly, it is vital to accomplish a real barrier result, which need to be water-proof if the timber is not to degrade also promptly.
This makes it possible to preserve natural, solid, raw, or veneered timber essentially over time. It is safeguarded to maintain for many years when faced with the different climatic aggressiveness experienced. It is durably maintained from moisture, rain, negative weather, light, sunlight, and also ultraviolet rays, making it age too soon. Plan View Furniture Vector
Stay Naturally Absorptive to Dampness
Continue to be moisture permeableStaying normally permeable to smoke is very essential. Wood is made up of plant fibers that have an exceptional affinity with water. It is, therefore, a breakable material that continues to be quickly absorptive to water. It stays particularly sensitive to various liquids that penetrate it.
Timber absorbs extremely quickly the moisture that is present in the ambient ambience. It soaks up water before normally launching it because it is a hygroscopic material. It continues to be in consistent balance with its environment, whatever the wetness web content.
These different humidity variants go to the beginning of the typical dimensional improvements of wood. They have the effect of triggering deformations that can often be substantial. It works by swelling if the air is also moist. It reduces when the ambience ends up being drier.
Rain, showers, electrical storms, and also various other poor weather condition that touch with the timber can create the appearance of unattractive discolorations, streaks, drips, and halos. Dampness, infiltration, condensation, and water vapor are additionally responsible for the early aging of timber for many years. Plan View Furniture Vector
Do Not Protect against Exchanges with The Outdoors.
Do not avoid exchanges with the outside not prevent interactions with the exterior; it needs to be valued. When you intend to shield the timber, a water-repellent product needs to be applied to avoid water from permeating it. It has to be made sure that it is not fertilized by dampness if it is to last over the long term.
A timber treatment product can just be completely appropriate if it appreciates the different dampness exchanges. The wood must be able to continue to manage itself with its atmosphere. It is important to make sure that the film continues to be completely micro-porous to ensure an excellent exchange performance.
On the other hand, impermeability and water tightness need to not be puzzled, which are extremely different ideas. Waterproofing has to be banned in the case of timber defense. Making a timber completely watertight might cause the product to rot in the long-term.
Gas exchange, which controls the dampness material in the timber’s pores, need to never be stopped. A wood paint have to enable the substrate to breathe without ever before stopping the inner discharge to the outside. It needs to just avoid water from permeating the heart of the timber, not to modify or degrade it.
Picking a Right Timber Treatment Product
Choosing a timber therapy picking the best wood therapy product is necessary to shield wood properly over time. There are different types of products that can effectively preserving this product. One can utilize a product that permeates deeply, such as oil, impregnation, or saturator.
A penetrating therapy supplies much more reliable defense than a product that deposits a film on the surface, such as paint, varnish, or sealer, for instance. While a film-forming item might appear valuable at first, this is not constantly the case in the lengthy term.
They can finish up fracturing, flaking, fracturing, or peeling off over the years. Seepage, water, or humidity passes through the product, which comes to be badly shielded. It is after that important to sand or strip the surface of the timber to bare it again to be maintained.
Silicones are widely utilized in wood waterproofing products. These unsafe substances ought to be stayed clear of similarly as oil solvents, which are still present in lots of products. They are not safe to the customer, the atmosphere, or nature. It is much better to pick a bio-sourced product of plant beginning that is consistent with this natural material.

Keep On A Regular Basis for Adequate Protection.
Keep forever protection keep frequently for an appropriate protection, continues to be an operation that must not be failed to remember to do. No matter the sort of waterproofing chosen to maintain the timber, it is necessary to preserve it routinely to ensure that the protection stays sufficiently effective with time.
Tiresome prep work, fining sand, gritting, or removing of the surface area can be stayed clear of using an oil, saturator, or impregnation. They have the particularity of shielding the product throughout its mass without creating a movie externally that can flake off later.
A waterproofing agent’s function is to protect the timber from stains, marks, rings, and everyday deterioration. It is usually associated with an anti UV representative that will stop the timber from becoming as well grey in the long run. It thus restricts the sensation of swelling or shrinkage.
A non-film-forming water repellent has several benefits for preserving a wooden surface area. It is extremely efficient versus negative weather condition thanks to an obstacle result. It stays really reliable in nourishing the wood in all its depth to the material’s very heart. It also secures the support from light, sun, as well as ultraviolet rays. Plan View Furniture Vector
