Outdoor wood has 2 main adversaries: UV (ultraviolet rays from sunlight) and moisture. The first causes a sort of surface melt – like on our skin, resulting in little cracks and greying. Nothing significant, the damage is mainly visual, as well as the wood is not influenced detailed. House Plan Furniture Template
Wetness poses a lot more extreme troubles: if rain does not run or does not vaporize quickly, if the timber continues to be in contact with the ground or if the moisture can climb by capillary activity, the moisture content of the timber will certainly allow the installation of lignivorous fungis that are precursors to rot and support strikes by wood-eating pests. Can chemical preservative therapies be avoided?
Resilient Variety, without Sapwood
Some normally sturdy species from our areas can be made use of without treatment when the timber is laid up and down (danger class 3) as well as allows good water drain (cladding, windows, shutters): in particular Douglas, larch, chestnut, oak, and grasshopper. Only the last three species are advised when the timber is laid horizontally (porch or terrace boards) or in contact with the ground (danger course 4). These woods must also be selected and cut in such a means as to eliminate the sapwood, the outer part of the trunk rich in sugars, which brings in wood-eating bugs. House Plan Furniture Template
What Are the Advantages of Safeguarding Your Timber?
Embellishes as well as Safeguards
Beyond maintaining the aesthetic aspect in time, using a wood oil or a saturator in the protection of wood will certainly revitalize its initial shade and boost the grain of the wood while keeping its all-natural appearance.
Stabilizes the Timber
Oiling a timber permits enhancing its dimensional stability durably, thus decreasing the sensations of contortion (tiling, swelling, and shrinkage), breaking, or surface splitting.
Natural and also Ecological
Picking an “Oleobois” protective oil implies selecting a healthy and balanced and eco-friendly service; the make-up omits fungicides, turpentine, and any kind of oil derivatives regularly used (paraffin, white spirit, …).
Easy as well as Economical Upkeep
Upkeep is very easy because once fueled oil; timber does not require to be stripped or sanded before improvement: a cleaning with black soap adhered to by an easy re-oiled surface area suffices. House Plan Furniture Template
Greying of The Timber
What Is Timber Graying?
Wood is a product virtually comprised of polysaccharides (cellulose as well as hemicelluloses) and also lignins that will be degraded under ultraviolet photons’ action. This photodegradation of the lignins, which is likewise accentuated in the visibility of water, is accountable for the evolution of the shade of the timber. Greying is observed on the wood made use of outdoors with no physical protection and also UV security. This sensation triggers a modification in the initial shade of the raw wood over time, which often tends to become gray.
What Are the Effects of Greying?
Greying or graying, which is an extremely surface phenomenon, only influences the wood framework’s appearances. It does not indicate an architectural change and also does not affect the strength of the material. The look of this sensation is restricted to the surface of the wood. The loss of structural sturdiness (which can reach the mess up of the material) is, for its part, due to attacks of biological beginning that affect the timber in its mass.
Is it possible to prevent the greying of the wood without maintaining it?
NO – Without ending up products and also without maintenance, it would be imaginary to declare to be able to avoid the wood from greying.
Will the application of a surface stop the wood from transforming grey?
YES – If this application is made consistently, it is possible to prevent this sensation. The hydrophobic nature of the oil strongly restricts the wood’s affinity for water as well as for that reason delays its action. House Plan Furniture Template
Corrected as well as Thermo-Oiled Timber
Numerous current processes have actually made it feasible to boost the durability and dimensional security of other types dramatically: these are high-temperature heat therapies (210 to 250 ° C )in a number of phases, performed in unique heaters, either under an inert ambience with nitrogen (rectified timber) or with water vapor shots (Finnish heat-treated lumber). The wood takes on a beautiful brown color and also ends up being hydrophobic and also very immune to fungal or insect assaults. Nevertheless, the high temperature compromises these timbers a little, which can not be made use of for structural functions (primarily in exterior siding, parquet, and terrace boards).
The so-called homeothermic process does not have this negative aspect: the wood is just heated up to 130 ° C, with an immersion in a blend based upon linseed oil and vegetable oil derivatives, which allows a deep impregnation. This likewise guarantees a longer resistance to greying and also does not require routine upkeep. The process creators have actually begun to market it in France: 3 manufacturers in the timber sector have actually already bought it, and also others are in the pipeline. The current Wood-Protect procedure patented by Lapeyre and also INRA-INPT in Toulouse is of the exact same type, with impregnation by autoclave and then by soaking at 140 ° C in a blend of vegetable oil by-products as well as acetic acid.

High-temperature therapies make the timber entirely water-proof as well as fungus immune.
The timber is brought to a temperature in between 210 ° C as well as 250 ° C in special ovens. It then alters shade to become darker. The major disadvantage is that it loses its toughness. It can after that only be made use of for cladding or flooring.
Oleothermy is a treatment that contains 3 phases: heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bathroom, as well as drying out. Because the home heating temperature level is less than the previous approach, the timber is less fragile.
Studies have actually shown that homeothermic home heating is useful when done after boron therapy. Boron has anti-inflammatory homes. The trouble is that it is not resistant to washing. Hence, the homeothermic makes it feasible to repair the particle and make the timber more immune to flames, water, and shocks. To read more about this method, below is a doctoral thesis that was done on the subject.
Oils, Stains, as well as Paints
The toughness of certain types such as oak as well as chestnut is mainly as a result of their high tannin content. These are gradually cleaned out by rain, which is slightly acidic. Like other species, oak and chestnut, as a result, need surface protection. Linseed oil with a little turpentine included – to be made use of in hot weather (it penetrates far better) – is traditional as well as inexpensive protection, water-repellent, and delays greying.
Organic wood stains, which are colored however reveal the timber grain, offer much better protection versus UV rays thanks to the pigments they have. Nevertheless, they need to be renewed every 3 to 5 years for the south exteriors and also every 8 to one decade for the north facades. Unlike paints, they do not call for sanding before revival (a brush stroke suffices to get rid of the pigment dirt). As for organic lacquer paints, they offer more durable defense since they contain fillers (specifically chalk) that create an entire screen against UV rays. It’s a little bit like sun creams; the safety depends on the display’s high quality and the direct exposure. House Plan Furniture Template
To improve the resilience of outside wood normally, select a discolor, for example, a mixture of linseed oil as well as turpentine. Some readily offered timber discolorations are tinted as well as supply slight UV security. The benefit of this approach is that no sanding is required.
For also better security, apply natural lacquer paint. It will offer ideal protection versus ultraviolet rays– favor microporous paints having chalk fillers to allow the wood breathe.
Shielding outside timber naturally can be done with a safety tarnish or warmth treatment. The option of approach depends on the characteristics that you desire to modify. If particular wood species can be made use of without protection, they have to be stained after a specific duration since the safety tannins will certainly have disappeared. If you do not do this, you will certainly need to have a specialist moisture treatment.
Securing Timber from Water
Safeguarding wood from water is an important feature of an outside finish before any kind of ornamental element. It is recommended to save the product with paint, varnish, discolor, saturator, or oil. It is essential to accomplish an actual obstacle impact, which must be water-proof if the wood is not to wear away too promptly.
This makes it possible to maintain all-natural, strong, raw, or veneered wood practically over time. It is secured to keep for many years despite the different climatic hostilities came across. It is durably maintained from moisture, rain, poor climate, light, sun, and also ultraviolet rays, making it age too soon. House Plan Furniture Template
Stay Normally Permeable to Dampness
Stay dampness permeableStaying normally permeable to smoke is really essential. Timber is composed of plant fibers that have an exceptional affinity with water. It is, consequently, a fragile product that continues to be conveniently permeable to water. It stays specifically sensitive to various liquids that permeate it.
Timber takes in really quickly the moisture that exists in the ambient atmosphere. It takes in water before naturally launching it since it is a hygroscopic product. It stays in consistent balance with its atmosphere, whatever the wetness content.
These various humidity variants go to the origin of the typical dimensional changes of timber. They have the impact of triggering deformations that can in some cases be substantial. It works by swelling if the air is as well damp. It diminishes when the atmosphere becomes drier.
Rainfall, showers, thunderstorms, and also other negative weather that touch with the timber can cause the appearance of unattractive discolorations, touches, trickles, and also halos. Wetness, infiltration, condensation, as well as water vapor are additionally responsible for the premature aging of timber for many years. House Plan Furniture Template
Do Not Avoid Exchanges with The Outside World.
Do not prevent exchanges with the outside not prevent communications with the exterior; it has to be respected. When you wish to secure the timber, a water-repellent item should be applied to prevent water from penetrating it. It has to be ensured that it is not impregnated by dampness if it is to last over the long-term.
A wood treatment product can just be completely ideal if it respects the various wetness exchanges. The timber should have the ability to continue to regulate itself with its environment. It is important to make sure that the film continues to be adequately micro-porous to ensure a good exchange efficiency.
On the other hand, impermeability and water tightness need to not be perplexed, which are extremely different notions. Waterproofing should be banned when it comes to timber defense. Making a wood completely watertight may cause the product to rot in the long-term.
Gas exchange, which regulates the dampness material in the timber’s pores, should never be prevented. A wood paint need to permit the substrate to take a breath without ever stopping the inner evacuation to the outside. It has to simply stop water from penetrating the heart of the wood, not to alter or degrade it.
Choosing a Right Wood Treatment Product
Choosing a wood treatment selecting the appropriate timber therapy item is essential to safeguard wood efficiently over time. There are various kinds of products that are capable of effectively maintaining this material. One can use an item that penetrates deeply, such as oil, impregnation, or saturator.
A penetrating treatment offers more reliable defense than a product that deposits a movie on the surface area, such as paint, varnish, or sealer. Certainly, while a film-forming product may seem helpful initially, this is not constantly the situation in the long term.
Undoubtedly, they can end up splitting, flaking, breaking, or peeling over the years. Seepage, water, or humidity passes through the product, which comes to be badly insulated. It is then vital to sand or strip the surface area of the wood to bare it again to be preserved.
Silicones are widely utilized in timber waterproofing products. These dangerous compounds must be avoided in the same way as oil solvents, which are still present in several items. They are not safe to the individual, the atmosphere, or nature. It is much better to choose a bio-sourced product of plant origin that is consistent with this natural material.

Maintain Regularly for Adequate Defense.
Maintain completely security maintain routinely for an ample protection, continues to be a procedure that needs to not be failed to remember to carry out. No matter the type of waterproofing selected to maintain the timber, it is required to keep it consistently to make sure that the protection stays adequately effective in time.
Tiresome prep work, sanding, gritting, or stripping of the surface can be prevented using an oil, saturator, or impregnation. They have the particularity of safeguarding the material throughout its mass without developing a movie externally that can flake off later.
A waterproofing representative’s function is to protect the timber from spots, marks, rings, and daily deterioration. It is typically associated with an anti UV representative that will prevent the wood from ending up being too grey over time. It therefore limits the phenomenon of swelling or contraction.
A non-film-forming water repellent has numerous advantages for maintaining a wood surface area. It is extremely effective against bad climate thanks to a barrier impact. It stays really effective in nurturing the timber in all its deepness to the product’s actual heart. It likewise safeguards the support from light, sun, and ultraviolet rays.
