Exterior wood has two primary adversaries: UV (ultraviolet rays from sunlight) and also humidity. The first causes a type of superficial shed – like on our skin, causing tiny fractures as well as greying. Nothing significant, the damage is mostly visual, as well as the wood is not affected in depth. Inter-Furniture Site Plan, Knitknot S Exhibition Design For Liquid La Habana .
Wetness poses far more severe troubles: if rainwater does not run off or does not vaporize rapidly, if the wood stays in contact with the ground or if the wetness can rise by capillary activity, the wetness content of the timber will certainly permit the installment of lignivorous fungis that are precursors to rot and also favor strikes by wood-eating bugs. Can chemical preservative therapies be avoided?
Durable Types, without Sapwood
Some normally resilient varieties from our regions can be made use of without treatment when the timber is laid vertically (danger class 3) as well as permits excellent water drain (cladding, home windows, shutters): in particular Douglas, larch, chestnut, oak, and locust. Just the last 3 types are recommended when the timber is laid flat (terrace or terrace boards) or in contact with the ground (danger course 4). These timbers have to also be chosen and also cut in such a means regarding get rid of the sapwood, the outer part of the trunk abundant in sugars, which brings in wood-eating insects.

What Are the Advantages of Shielding Your Timber?
Embellishes and also Shields
Past maintaining the visual element gradually, using a timber oil or a saturator in the defense of timber will restore its initial color as well as improve the grain of the timber while maintaining its all-natural look.
Maintains the Wood
Fueling oil a wood permits boosting its dimensional stability durably, thus minimizing the phenomena of deformation (tiling, swelling, as well as shrinking), fracturing, or surface area splitting.
All-natural and Ecological
Choosing an “Oleobois” protective oil means selecting a healthy and eco-friendly solution; the make-up leaves out fungicides, turpentine, as well as any kind of petroleum derivatives often used (paraffin, white spirit, …).
Easy and Economical Upkeep
Maintenance is very easy due to the fact that when oiled; timber does not require to be stripped or fined sand before remodelling: a cleansing with black soap complied with by an easy re-oiled surface is enough. Inter-Furniture Site Plan, Knitknot S Exhibition Design For Liquid La Habana .
Greying of The Timber
What Is Wood Graying?
Wood is a product almost comprised of polysaccharides (cellulose and also hemicelluloses) and also lignins that will certainly be degraded under ultraviolet photons’ activity. This photodegradation of the lignins, which is additionally accentuated in the presence of water, is in charge of the advancement of the color of the wood. Greying is observed on the wood used outdoors without any physical protection and also UV protection. This phenomenon creates a modification in the original color of the raw wood over time, which often tends to end up being gray.
What Are the Repercussions of Greying?
Greying or graying, which is a really shallow phenomenon, just influences the wood structure’s appearances. It does not show an architectural change and also does not impact the solidity of the product. The look of this sensation is restricted to the surface area of the wood. The loss of architectural resilience (which can reach the mess up of the product) is, for its component, as a result of strikes of biological beginning that affect the wood in its mass.
Is it feasible to avoid the greying of the timber without keeping it?
NO – Without ending up products and without maintenance, it would certainly be illusory to declare to be able to stop the timber from greying.
Will the application of a surface stop the timber from transforming grey?
YES – If this application is made routinely, it is feasible to avoid this phenomenon. The hydrophobic nature of the oil highly restricts the timber’s fondness for water and as a result postpones its action. Inter-Furniture Site Plan, Knitknot S Exhibition Design For Liquid La Habana .
Remedied and Thermo-Oiled Wood
Numerous current processes have made it feasible to improve the longevity and also dimensional stability of other varieties substantially: these are high-temperature heat therapies (210 to 250 ° C )in a number of stages, carried out in unique heating systems, either under an inert environment with nitrogen (corrected wood) or with water vapor injections (Finnish heat-treated lumber). The timber tackles a lovely brownish shade and comes to be hydrophobic as well as really immune to fungal or insect attacks. The high temperature level damages these timbers a little, which can not be made use of for structural objectives (mainly in house siding, parquet, and balcony boards).
The so-called homeothermic process does not have this downside: the timber is only warmed up to 130 ° C, with an immersion in a mix based on linseed oil and also grease derivatives, which enables a deep impregnation. This additionally ensures a longer resistance to greying and also does not call for routine maintenance. The procedure developers have begun to market it in France: 3 makers in the timber sector have actually already bought it, and also others remain in the pipe. The current Wood-Protect process patented by Lapeyre and also INRA-INPT in Toulouse is of the same kind, with impregnation by autoclave and then by saturating at 140 ° C in a combination of grease by-products and also acetic acid.

High-temperature treatments make the wood wholly waterproof and fungus immune.
The wood is brought to a temperature level in between 210 ° C and also 250 ° C in special ovens. It then alters color to become darker. The primary negative aspect is that it loses its stamina. It can after that just be used for cladding or flooring.
Oleothermy is a therapy that includes 3 stages: home heating to 130 ° C in a rapeseed oil bath, cooling down in a linseed oil bathroom, and drying out. Given that the heating temperature level is less than the previous method, the wood is much less breakable.
Researches have revealed that homeothermic heating is beneficial when done after boron treatment. Boron has anti-inflammatory residential properties. The trouble is that it is not immune to washing. Hence, the homeothermic makes it possible to deal with the particle and also make the timber a lot more immune to flames, water, and shocks. To learn more concerning this technique, here is a doctoral thesis that was done on the topic.
Oils, Discolorations, and also Paints
The longevity of certain varieties such as oak and chestnut is primarily due to their high tannin material. These are slowly washed out by rainwater, which is somewhat acidic. Like other species, oak and also chestnut, therefore, call for surface security. Linseed oil with a little turpentine added – to be utilized in heat (it permeates much better) – is classic and affordable defense, water-repellent, and hold-ups greying.
Organic wood spots, which are colored but show the wood grain, supply far better security against UV rays thanks to the pigments they consist of. Nonetheless, they need to be renewed every 3 to 5 years for the south exteriors and every 8 to one decade for the north facades. Unlike paints, they do not require sanding prior to revival (a brush stroke suffices to eliminate the pigment dirt). When it comes to organic lacquer paints, they supply even more sturdy security considering that they consist of fillers (particularly chalk) that create an entire screen versus UV rays. It’s a bit like sun creams; the safety and security depends on the screen’s quality and the exposure. Inter-Furniture Site Plan, Knitknot S Exhibition Design For Liquid La Habana .
To improve the resilience of exterior timber normally, select a stain, for instance, a mixture of linseed oil as well as turpentine. Some commercially readily available timber spots are colored as well as give mild UV security. The benefit of this technique is that no sanding is called for.
For also much better protection, use natural lacquer paint. It will certainly supply ideal defense versus ultraviolet rays– prefer microporous paints having chalk fillers to let the wood breathe.
Shielding external wood naturally can be finished with a safety discolor or warmth treatment. The choice of technique depends upon the features that you want to change. If specific timber types can be utilized without security, they have to be discolored after a certain duration due to the fact that the safety tannins will certainly have vanished. If you do refrain from doing this, you will have to have a professional moisture treatment.
Protecting Timber from Water
Securing wood from water is a necessary function of an exterior finish prior to any ornamental aspect. It is recommended to save the product with paint, varnish, tarnish, saturator, or oil. Indeed, it is necessary to accomplish a genuine obstacle effect, which have to be waterproof if the timber is not to deteriorate too quickly.
This makes it possible to protect natural, strong, raw, or veneered wood basically over time. It is shielded to keep for years in the face of the different climatic hostilities experienced. It is durably maintained from moisture, rainfall, negative climate, light, sun, and ultraviolet rays, making it age prematurely.

Remain Normally Permeable to Moisture
Continue to be dampness permeableStaying normally absorptive to smoke is very crucial. Wood is composed of plant fibers that have an exceptional fondness with water. It is, as a result, a breakable material that remains conveniently absorptive to water. It continues to be especially sensitive to numerous liquids that penetrate it.
Timber soaks up extremely quickly the humidity that is present in the ambient environment. It soaks up water prior to normally releasing it due to the fact that it is a hygroscopic material. It remains in constant stability with its environment, whatever the dampness web content.
These different moisture variants are at the origin of the typical dimensional improvements of timber. They have the impact of creating contortions that can in some cases be considerable. It functions by swelling if the air is also moist. It diminishes when the ambience comes to be drier.
Rainfall, showers, thunderstorms, as well as various other poor weather that touch with the timber can cause the appearance of unpleasant stains, touches, leaks, as well as halos. Dampness, infiltration, condensation, and water vapor are additionally in charge of the early aging of timber for many years.

Do Not Prevent Exchanges with The Outdoors.
Do not stop exchanges with the outdoors not avoid interactions with the outside; it needs to be valued. When you intend to secure the timber, a water-repellent product should be put on stay clear of water from penetrating it. It must be made certain that it is not fertilized by dampness if it is to last over the long term.
A timber therapy item can only be completely suitable if it values the various dampness exchanges. The wood has to be able to continue to control itself with its environment. It is important to guarantee that the film continues to be completely micro-porous to guarantee an excellent exchange effectiveness.
On the other hand, impermeability and water rigidity need to not be puzzled, which are very various notions. Waterproofing needs to be restricted when it comes to timber protection. Making a timber entirely watertight might cause the material to rot in the long term.
Gas exchange, which controls the wetness material in the wood’s pores, have to never be protected against. A timber paint must enable the substrate to breathe without ever before quiting the inner emptying to the exterior. It needs to simply protect against water from penetrating the heart of the wood, not to change or weaken it.
Selecting a Right Timber Therapy Item
Selecting a wood treatment selecting the appropriate wood therapy product is essential to secure timber successfully with time. There are different types of products that can successfully preserving this material. One can use a product that permeates deeply, such as oil, impregnation, or saturator.
A permeating treatment gives more efficient protection than an item that transfers a film on the surface area, such as paint, varnish, or sealant. While a film-forming product may seem helpful originally, this is not always the situation in the long term.
Without a doubt, they can wind up cracking, flaking, cracking, or peeling off for many years. Seepage, water, or moisture penetrates the product, which ends up being improperly insulated. It is then necessary to sand or strip the surface area of the timber to bare it again to be preserved.
Silicones are extensively utilized in wood waterproofing items. These hazardous compounds need to be avoided similarly as oil solvents, which are still existing in several products. They are not harmless to the customer, the setting, or nature. It is better to select a bio-sourced product of plant origin that follows this all-natural material.

Keep Regularly for Adequate Security.
Preserve forever security preserve regularly for an appropriate defense, stays a procedure that needs to not be neglected to execute. Despite the sort of waterproofing selected to protect the wood, it is necessary to maintain it routinely so that the security remains completely efficient gradually.
Laborious prep work, sanding, gritting, or stripping of the surface can be avoided utilizing an oil, saturator, or impregnation. They have the particularity of securing the product throughout its mass without producing a movie on the surface that can flake off afterward.
A waterproofing representative’s feature is to protect the wood from stains, marks, rings, as well as daily wear and tear. It is generally connected with an anti UV representative that will avoid the timber from ending up being as well grey in the long run. It hence restricts the sensation of swelling or contraction.
A non-film-forming water repellent has several benefits for maintaining a wood surface. It is very reliable against poor weather condition thanks to a barrier impact. It stays extremely efficient in nourishing the timber in all its depth to the product’s very heart. It also protects the support from light, sunlight, as well as ultraviolet rays.
