Outside timber has 2 primary opponents: UV (ultraviolet rays from sunlight) and also moisture. The first causes a sort of shallow melt – like on our skin, leading to tiny splits and also greying. Nothing remarkable, the damage is generally aesthetic, and also the wood is not affected detailed. North American Wood Furniture Plan 166L Lhf
Dampness postures far more severe problems: if rainwater does not run off or does not evaporate promptly, if the timber remains touching the ground or if the moisture can increase by capillary action, the dampness content of the timber will allow the installment of lignivorous fungi that are precursors to rot and also support attacks by wood-eating pests. Can chemical preservative treatments be prevented?
Long lasting Types, without Sapwood
Some naturally durable varieties from our areas can be used without therapy when the wood is laid up and down (risk course 3) as well as enables good water drain (cladding, home windows, shutters): in particular Douglas, larch, chestnut, oak, as well as cicada. Only the last three varieties are recommended when the wood is laid flat (balcony or terrace boards) or in contact with the ground (danger course 4). These woods need to also be picked and also cut in such a way regarding eliminate the sapwood, the outer part of the trunk rich in sugars, which brings in wood-eating pests.

What Are the Benefits of Securing Your Wood?
Embellishes and also Secures
Past preserving the aesthetic element in time, making use of a timber oil or a saturator in the defense of wood will revitalize its original shade and also improve the grain of the timber while keeping its natural look.
Stabilizes the Timber
Oiling a timber enables boosting its dimensional security durably, thus minimizing the phenomena of contortion (tiling, swelling, and shrinkage), fracturing, or surface splitting.
Natural and Ecological
Picking an “Oleobois” protective oil means selecting a healthy and also environmentally friendly option; the make-up omits fungicides, turpentine, and any oil by-products often utilized (paraffin, white spirit, …).
Easy as well as Economical Upkeep
Maintenance is very easy due to the fact that once oiled; timber does not require to be stripped or sanded prior to restoration: a cleaning with black soap adhered to by a straightforward re-oiled surface is enough. North American Wood Furniture Plan 166L Lhf
Greying of The Timber
What Is Wood Graying?
Timber is a material nearly made up of polysaccharides (cellulose and also hemicelluloses) as well as lignins that will certainly be degraded under ultraviolet photons’ action. This photodegradation of the lignins, which is additionally emphasized in the existence of water, is responsible for the development of the shade of the wood. Greying is observed on the wood made use of outdoors with no physical defense and UV defense. This phenomenon causes a modification in the original color of the raw wood in time, which often tends to end up being gray.
What Are the Effects of Greying?
Greying or graying, which is a really shallow sensation, just impacts the wooden framework’s visual appeals. It does not indicate an architectural alteration and does not affect the solidity of the product. The appearance of this phenomenon is restricted to the surface of the wood. The loss of structural toughness (which can go as far as the destroy of the product) is, for its part, as a result of assaults of biological origin that impact the timber in its mass.
Is it feasible to stay clear of the greying of the wood without maintaining it?
NO – Without completing items and also without upkeep, it would be illusory to declare to be able to avoid the timber from greying.
Will the application of a coating stop the timber from transforming grey?
YES – If this application is made frequently, it is feasible to avoid this phenomenon. The hydrophobic nature of the oil strongly limits the wood’s affinity for water as well as for that reason delays its activity. North American Wood Furniture Plan 166L Lhf
Rectified and also Thermo-Oiled Timber
A number of recent processes have actually made it possible to boost the sturdiness as well as dimensional security of various other types significantly: these are high-temperature heat treatments (210 to 250 ° C )in numerous phases, executed in unique furnaces, either under an inert atmosphere with nitrogen (corrected wood) or with water vapor shots (Finnish heat-treated lumber). The timber handles an attractive brown color as well as becomes hydrophobic and extremely resistant to fungal or insect attacks. The high temperature level deteriorates these timbers a little, which can not be utilized for structural functions (generally in siding, parquet, and also balcony boards).
The so-called homeothermic process does not have this negative aspect: the wood is only warmed up to 130 ° C, with an immersion in a mixture based upon linseed oil as well as vegetable oil by-products, which enables a deep impregnation. This additionally ensures a much longer resistance to greying and does not require routine upkeep. The process makers have actually started to market it in France: three producers in the wood market have actually already bought it, and also others are 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 afterwards by soaking at 140 ° C in a mix of grease by-products and also acetic acid.

High-temperature therapies make the wood wholly waterproof and also fungus resistant.
The timber is brought to a temperature level between 210 ° C and also 250 ° C in unique stoves. It then alters color to become darker. The major negative aspect is that it loses its stamina. It can after that only be made use of for cladding or flooring.
Oleothermy is a therapy that includes 3 stages: heating to 130 ° C in a rapeseed oil bath, cooling in a linseed oil bath, and drying. Considering that the heating temperature level is lower than the previous technique, the wood is much less breakable.
Researches have shown that homeothermic heating is valuable when done after boron therapy. Boron has anti-inflammatory properties. The issue is that it is not resistant to washing. Therefore, the homeothermic makes it possible to repair the particle and also make the timber much more resistant to fires, water, and also shocks. To read more regarding this method, below is a doctoral thesis that was done on the topic.
Oils, Stains, and Paints
The toughness of certain varieties such as oak and chestnut is mainly because of their high tannin content. Nonetheless, these are gradually rinsed by rain, which is slightly acidic. Like various other varieties, oak and chestnut, therefore, require surface area defense. Linseed oil with a little turpentine added – to be made use of in hot weather (it permeates much better) – is timeless and economical defense, water-repellent, and delays greying.
Organic wood discolorations, which are colored but show the timber grain, give better security versus UV rays thanks to the pigments they include. They ought to be restored every 3 to 5 years for the south facades and every 8 to 10 years for the north facades. Unlike paints, they do not need sanding before revival (a brush stroke is enough to get rid of the pigment dirt). When it comes to natural lacquer paints, they offer more durable defense since they contain fillers (particularly chalk) that develop a whole screen against UV rays. It’s a little bit like sun creams; the security depends on the screen’s quality as well as the exposure. North American Wood Furniture Plan 166L Lhf
Surface area Security
To enhance the durability of outdoor wood naturally, go with a stain, for example, a mix of linseed oil and turpentine. Some commercially available wood stains are colored and provide small UV protection. The benefit of this method is that no sanding is required.
For also far better protection, apply natural lacquer paint. It will offer optimal security against ultraviolet rays– prefer microporous paints including chalk fillers to let the wood breathe.
Securing outside timber naturally can be performed with a safety discolor or warmth treatment. The selection of approach relies on the attributes that you wish to customize. If particular timber species can be utilized without security, they should be stained after a particular duration because the protective tannins will certainly have disappeared. If you do not do this, you will have to have a specialist moisture treatment.
Protecting Timber from Water
Securing timber from water is a crucial function of an outside finish before any kind of ornamental facet. It is advised to conserve the product with paint, varnish, tarnish, saturator, or oil. It is vital to accomplish a genuine barrier effect, which need to be waterproof if the wood is not to degrade too rapidly.
This makes it possible to maintain all-natural, solid, raw, or veneered wood basically gradually. It is shielded to keep for years when faced with the various climatic aggressions ran into. It is durably preserved from humidity, rainfall, negative climate, light, sunlight, as well as ultraviolet rays, making it age too soon. North American Wood Furniture Plan 166L Lhf
Stay Naturally Permeable to Moisture
Remain wetness permeableStaying normally absorptive to smoke is very essential. Timber is composed of plant fibers that have an outstanding fondness with water. It is, for that reason, a vulnerable product that remains easily permeable to water. It continues to be specifically conscious various liquids that penetrate it.
Wood takes in very promptly the humidity that is present in the ambient environment. It absorbs water prior to naturally releasing it due to the fact that it is a hygroscopic product. It continues to be in constant equilibrium with its atmosphere, whatever the dampness content.
These various moisture variants go to the origin of the usual dimensional changes of wood. They have the effect of causing deformations that can sometimes be considerable. It works by swelling if the air is as well humid. It diminishes when the environment comes to be drier.
Rain, showers, electrical storms, and also various other bad weather condition that touch with the timber can cause the appearance of unsightly spots, streaks, drips, and halos. Wetness, infiltration, condensation, and water vapor are likewise in charge of the early aging of wood for many years. North American Wood Furniture Plan 166L Lhf
Do Not Avoid Exchanges with The Outdoors.
Do not protect against exchanges with the outdoors not avoid interactions with the outside; it needs to be valued. When you want to safeguard the timber, a water-repellent item has to be put on prevent water from penetrating it. It needs to be made sure that it is not impregnated by wetness if it is to last over the long-term.
A wood treatment item can just be completely suitable if it appreciates the different moisture exchanges. The timber must have the ability to continue to regulate itself with its environment. It is vital to make certain that the movie stays sufficiently micro-porous to assure a great exchange efficiency.
On the other hand, impermeability and water rigidity need to not be perplexed, which are very different notions. Waterproofing needs to be prohibited in the case of timber security. Making a wood entirely watertight might trigger the product to rot in the long-term.
Gas exchange, which manages the moisture web content in the wood’s pores, should never be stopped. A timber paint must allow the substrate to breathe without ever before stopping the interior evacuation to the exterior. It has to just protect against water from penetrating the heart of the wood, not to modify or weaken it.
Selecting a Right Wood Therapy Product
Selecting a timber therapy choosing the ideal timber therapy item is important to safeguard timber effectively gradually. There are various sorts of items that can effectively protecting this material. One can use an item that permeates deeply, such as oil, impregnation, or saturator.
A passing through treatment gives more reliable defense than a product that deposits a film externally, such as paint, varnish, or sealer, as an example. Indeed, while a film-forming product may appear valuable initially, this is not constantly the situation in the long term.
They can finish up splitting, flaking, breaking, or peeling off over the years. Infiltration, water, or moisture passes through the material, which becomes poorly insulated. It is after that important to sand or strip the surface area of the wood to bare it again to be preserved.
Silicones are commonly used in wood waterproofing products. These unsafe substances need to be avoided similarly as oil solvents, which are still present in numerous items. They are not harmless to the user, the setting, or nature. It is far better to pick a bio-sourced product of plant beginning that is consistent with this natural product.

Maintain Routinely for Adequate Defense.
Maintain completely security preserve routinely for an adequate defense, stays a procedure that ought to not be forgotten to perform. Regardless of the kind of waterproofing chosen to protect the timber, it is needed to maintain it consistently so that the protection continues to be sufficiently effective gradually.
Tedious prep work, fining sand, gritting, or removing of the surface can be stayed clear of making use of an oil, saturator, or impregnation. They have the particularity of protecting the product throughout its mass without developing a film externally that can exfoliate later.
A waterproofing agent’s function is to protect the timber from discolorations, marks, rings, and everyday wear and tear. It is normally associated with an anti UV agent that will certainly prevent the wood from becoming as well grey in the future. It therefore restricts the sensation of swelling or shrinkage.
A non-film-forming water repellent has lots of advantages for preserving a wood surface. It is extremely efficient versus poor weather condition thanks to an obstacle result. Also, it stays very effective in nurturing the wood in all its depth to the material’s actual heart. It likewise secures the assistance from light, sunlight, and ultraviolet rays.
