Outdoor timber has 2 major adversaries: UV (ultraviolet rays from sunlight) and humidity. The first causes a type of superficial melt – like on our skin, causing little cracks and greying. Nothing dramatic, the damages is generally aesthetic, and also the wood is not impacted comprehensive. Draw A Furniture Plan
Wetness presents much more extreme problems: if rain does not run or does not evaporate promptly, if the wood stays touching the ground or if the moisture can climb by capillary activity, the moisture material of the timber will certainly permit the installation of lignivorous fungi that are forerunners to rot as well as favor assaults by wood-eating insects. Can chemical preservative treatments be stayed clear of?
Long lasting Species, without Sapwood
Some normally long lasting types from our areas can be utilized without treatment when the timber is laid vertically (risk class 3) and also enables great water drainage (cladding, windows, shutters): particularly Douglas, larch, chestnut, oak, as well as grasshopper. Just the last 3 types are recommended when the timber is laid flat (porch or terrace boards) or touching the ground (risk class 4). These timbers need to additionally be chosen and also cut in such a way regarding remove the sapwood, the outer part of the trunk abundant in sugars, which draws in wood-eating pests.

What Are the Benefits of Safeguarding Your Timber?
Embellishes and also Secures
Past preserving the aesthetic aspect in time, utilizing a timber oil or a saturator in the protection of timber will revive its original color as well as enhance the grain of the timber while keeping its natural look.
Maintains the Timber
Fueling oil a wood allows improving its dimensional stability durably, therefore reducing the phenomena of contortion (tiling, swelling, and also contraction), splitting, or surface area splitting.
All-natural and Ecological
Choosing an “Oleobois” safety oil suggests picking a healthy and balanced and environmentally friendly solution; the composition excludes fungicides, turpentine, as well as any kind of oil by-products frequently made use of (paraffin, white spirit, …).
Easy and also Economical Upkeep
Maintenance is very easy because when oiled; wood does not require to be stripped or fined sand before restoration: a cleansing with black soap adhered to by an easy re-oiled surface area is enough. Draw A Furniture Plan
Greying of The Wood
What Is Wood Graying?
Timber is a product nearly comprised of polysaccharides (cellulose and hemicelluloses) as well as lignins that will certainly be deteriorated under ultraviolet photons’ action. This photodegradation of the lignins, which is likewise highlighted in the existence of water, is accountable for the evolution of the shade of the timber. Greying is observed on the lumber made use of outdoors without any physical protection as well as UV protection. This sensation creates a modification in the initial shade of the raw wood gradually, which often tends to end up being grey.
What Are the Repercussions of Greying?
Greying or graying, which is a really shallow phenomenon, only impacts the wood structure’s aesthetics. It does not show a structural change and does not affect the solidity of the material. The appearance of this phenomenon is limited to the surface area of the timber. The loss of architectural toughness (which can go as far as the wreck of the material) is, for its component, because of strikes of organic origin that impact the timber in its mass.
Is it possible to avoid the greying of the wood without keeping it?
NO – Without ending up products and without maintenance, it would be illusory to claim to be able to prevent the wood from greying.
Will the application of a finish avoid the timber from turning gray?
YES – If this application is made routinely, it is feasible to avoid this sensation. The hydrophobic nature of the oil highly limits the wood’s affinity for water as well as consequently postpones its activity. Draw A Furniture Plan
Fixed and Thermo-Oiled Wood
Numerous recent processes have made it feasible to boost the resilience and also dimensional security of various other types dramatically: these are high-temperature warmth therapies (210 to 250 ° C )in numerous phases, executed in unique heaters, either under an inert ambience with nitrogen (rectified wood) or with water vapor shots (Finnish heat-treated lumber). The wood tackles an attractive brown shade and also becomes hydrophobic and really resistant to fungal or insect attacks. The high temperature level deteriorates these woods a little, which can not be utilized for structural purposes (mostly in home siding, parquet, and balcony boards).
The so-called homeothermic process does not have this downside: the timber is just warmed up to 130 ° C, with an immersion in a combination based on linseed oil and grease derivatives, which permits a deep impregnation. This also makes certain a longer resistance to greying as well as does not need normal upkeep. The process makers have actually started to market it in France: 3 makers in the timber sector have currently bought it, as well as others are in the pipeline. The recent Wood-Protect procedure patented by Lapeyre and INRA-INPT in Toulouse is of the exact same type, with impregnation by autoclave and after that by saturating at 140 ° C in a mixture of vegetable oil derivatives and also acetic acid.

High-temperature treatments make the wood entirely waterproof as well as fungus immune.
The wood is brought to a temperature in between 210 ° C and 250 ° C in special ovens. It then transforms shade to become darker. The major negative aspect is that it sheds its toughness. It can after that only be used for cladding or flooring.
Oleothermy is a therapy that consists of 3 stages: heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bath, and also drying. Since the home heating temperature is less than the previous method, the timber is less brittle.
Researches have shown that homeothermic home heating is beneficial when done after boron therapy. Boron has anti-inflammatory residential or commercial properties. The issue is that it is not resistant to washing. Hence, the homeothermic makes it possible to repair the particle as well as make the wood extra immune to fires, water, as well as shocks. For more information concerning this method, below is a doctoral thesis that was done on the topic.
Oils, Discolorations, and Paints
The longevity of specific types such as oak and chestnut is primarily due to their high tannin material. These are gradually washed out by rain, which is slightly acidic. Like various other varieties, oak and chestnut, for that reason, need surface defense. Linseed oil with a little turpentine included – to be used in heat (it penetrates much better) – is traditional and also affordable defense, water-repellent, as well as hold-ups greying.
Organic wood stains, which are tinted but show the wood grain, offer much better defense against UV rays thanks to the pigments they consist of. They should be renewed every 3 to 5 years for the south exteriors and also every 8 to 10 years for the north exteriors. Unlike paints, they do not require sanding prior to renewal (a brush stroke is enough to remove the pigment dust). As for natural lacquer paints, they supply more long lasting defense considering that they have fillers (specifically chalk) that develop an entire display against UV rays. It’s a little bit like sun creams; the safety and security relies on the screen’s top quality and the direct exposure. Draw A Furniture Plan
Surface area Protection
To enhance the sturdiness of exterior timber naturally, choose a tarnish, as an example, a mix of linseed oil and turpentine. Some commercially offered timber stains are colored and also provide mild UV defense. The advantage of this method is that no sanding is required.
For also better protection, apply natural lacquer paint. It will provide optimum security versus ultraviolet rays– prefer microporous paints having chalk fillers to let the wood take a breath.
Securing external wood normally can be finished with a safety tarnish or warm treatment. The choice of method depends upon the qualities that you desire to modify. If certain wood varieties can be made use of without protection, they should be stained after a certain duration because the safety tannins will certainly have disappeared. If you do refrain from doing this, you will certainly need to have a specialist dampness therapy.
Securing Wood from Water
Protecting wood from water is a vital function of an exterior finish prior to any type of attractive facet. It is advised to save the material with paint, varnish, discolor, saturator, or oil. It is necessary to accomplish an actual obstacle impact, which should be water-proof if the wood is not to deteriorate too promptly.
This makes it feasible to protect all-natural, solid, raw, or veneered wood basically in time. It is secured to keep for several years despite the various weather aggressions came across. It is durably preserved from humidity, rain, bad weather condition, light, sun, as well as ultraviolet rays, making it age prematurely. Draw A Furniture Plan
Continue To Be Normally Absorptive to Wetness
Stay wetness permeableStaying normally permeable to smoke is extremely vital. Timber is composed of plant fibers that have a superb affinity with water. It is, as a result, a fragile material that continues to be conveniently absorptive to water. It continues to be specifically sensitive to different liquids that permeate it.
Timber soaks up very promptly the humidity that exists in the ambient atmosphere. It soaks up water before normally launching it due to the fact that it is a hygroscopic material. It stays in constant stability with its environment, whatever the wetness material.
These different humidity variations are at the beginning of the usual dimensional makeovers of wood. They have the result of creating contortions that can sometimes be substantial. It functions by swelling if the air is too humid. It shrinks when the ambience becomes drier.
Rainfall, showers, electrical storms, and also other poor climate that touch with the wood can cause the look of unattractive discolorations, touches, leaks, and also halos. Moisture, seepage, condensation, and also water vapor are additionally responsible for the early aging of wood for many years. Draw A Furniture Plan
Do Not Avoid Exchanges with The Outside World.
Do not stop exchanges with the outside not prevent communications with the exterior; it should be respected. When you wish to protect the wood, a water-repellent item has to be related to avoid water from permeating it. It has to be made certain that it is not fertilized by moisture if it is to last over the long term.
A timber treatment product can only be completely suitable if it respects the different wetness exchanges. The timber must have the ability to remain to control itself with its environment. It is essential to make sure that the movie continues to be completely micro-porous to assure a great exchange efficiency.
On the other hand, impermeability as well as water rigidity need to not be puzzled, which are very various notions. Waterproofing needs to be forbidden in the case of wood defense. Making a wood entirely watertight may trigger the material to rot in the long term.
Gas exchange, which controls the wetness content in the wood’s pores, should never be protected against. A timber paint should permit the substratum to breathe without ever quiting the interior evacuation to the outside. It must just avoid water from permeating the heart of the wood, not to change or degrade it.
Choosing a Right Wood Treatment Product
Selecting a wood treatment choosing the right wood treatment item is important to protect timber successfully with time. There are different kinds of items that can successfully preserving this product. One can make use of an item that permeates deeply, such as oil, impregnation, or saturator.
A passing through therapy offers much more effective defense than a product that deposits a film on the surface, such as paint, varnish, or sealer. Certainly, while a film-forming item might appear beneficial initially, this is not constantly the case in the long-term.
Indeed, they can wind up cracking, flaking, cracking, or removing over the years. Infiltration, water, or humidity permeates the product, which ends up being badly protected. It is after that necessary to sand or strip the surface of the wood to bare it once more to be protected.
Silicones are commonly used in timber waterproofing products. These dangerous materials need to be stayed clear of in the same way as oil solvents, which are still existing in numerous products. They are not harmless to the individual, the setting, or nature. It is far better to choose a bio-sourced item of plant beginning that is consistent with this all-natural material.

Maintain Routinely for Adequate Defense.
Preserve for good defense maintain routinely for an ample defense, stays an operation that must not be neglected to carry out. Regardless of the kind of waterproofing picked to protect the wood, it is essential to keep it routinely to make sure that the security continues to be completely efficient gradually.
Tiresome preparation, sanding, gritting, or removing of the surface can be avoided making use of an oil, saturator, or impregnation. They have the particularity of safeguarding the product throughout its mass without producing a film externally that can flake off afterward.
A waterproofing agent’s feature is to secure the timber from stains, marks, rings, as well as day-to-day damage. It is usually related to an anti UV agent that will stop the wood from coming to be as well grey in the future. It therefore limits the sensation of swelling or shrinking.
A non-film-forming water repellent has lots of benefits for maintaining a wood surface. It is very efficient against poor weather condition thanks to an obstacle impact. Likewise, it remains really reliable in nurturing the wood in all its deepness to the material’s very heart. It also secures the assistance from light, sun, as well as ultraviolet rays.
