Outdoor timber has two major adversaries: UV (ultraviolet rays from sunlight) and also humidity. The first causes a type of shallow burn – like on our skin, leading to little cracks and also greying. Nothing significant, the damages is generally visual, and also the timber is not affected comprehensive. Scenic Design Basic Furniture Ground Plan
Moisture positions much more severe problems: if rainwater does not run off or does not evaporate quickly, if the timber remains in contact with the ground or if the moisture can climb by capillary activity, the moisture material of the timber will certainly permit the installment of lignivorous fungi that are precursors to rot and favor strikes by wood-eating bugs. Can chemical preservative therapies be avoided?
Sturdy Types, without Sapwood
Some normally resilient species from our areas can be made use of without treatment when the wood is laid vertically (risk course 3) and also permits good water drain (cladding, home windows, shutters): in particular Douglas, larch, chestnut, oak, as well as locust. Just the last three types are suggested when the wood is laid horizontally (terrace or terrace boards) or in contact with the ground (risk class 4). These woods need to likewise be picked and cut in such a way regarding eliminate the sapwood, the peripheral part of the trunk abundant in sugars, which brings in wood-eating bugs.

What Are the Advantages of Protecting Your Timber?
Embellishes as well as Safeguards
Past preserving the aesthetic facet over time, making use of a timber oil or a saturator in the security of wood will revitalize its initial shade and also enhance the grain of the timber while keeping its natural appearance.
Supports the Timber
Oiling a wood permits improving its dimensional security durably, therefore minimizing the phenomena of deformation (tiling, swelling, and shrinkage), cracking, or surface splitting.
Natural as well as Ecological
Picking an “Oleobois” safety oil indicates picking a healthy and balanced and environmentally friendly option; the composition excludes fungicides, turpentine, as well as any type of petroleum by-products regularly used (paraffin, white spirit, …).
Easy and Economical Upkeep
Upkeep is easy because when fueled oil; timber does not require to be stripped or sanded prior to restoration: a cleansing with black soap followed by a straightforward re-oiled surface suffices. Scenic Design Basic Furniture Ground Plan
Greying of The Wood
What Is Timber Graying?
Timber is a product almost comprised of polysaccharides (cellulose and also hemicelluloses) and also lignins that will be weakened under ultraviolet photons’ action. This photodegradation of the lignins, which is also emphasized in the existence of water, is responsible for the development of the shade of the timber. Greying is observed on the lumber utilized outdoors with no physical security as well as UV security. This sensation creates an adjustment in the initial shade of the raw wood gradually, which tends to become gray.
What Are the Effects of Greying?
Greying or graying, which is a really shallow sensation, only influences the wooden structure’s visual appeals. It does not indicate a structural modification as well as does not affect the solidity of the material. The look of this phenomenon is restricted to the surface area of the timber. The loss of structural sturdiness (which can reach the wreck of the product) is, for its component, as a result of attacks of biological origin that impact the wood in its mass.
Is it possible to stay clear of the greying of the wood without keeping it?
NO – Without finishing items and without maintenance, it would certainly be illusory to claim to be able to avoid the timber from greying.
Will the application of a surface prevent the wood from transforming grey?
YES – If this application is made regularly, it is feasible to avoid this sensation. The hydrophobic nature of the oil strongly restricts the wood’s affinity for water as well as as a result postpones its action. Scenic Design Basic Furniture Ground Plan
Corrected and also Thermo-Oiled Timber
Several recent processes have actually made it feasible to improve the durability and dimensional security of other species substantially: these are high-temperature heat therapies (210 to 250 ° C )in numerous phases, carried out in special furnaces, either under an inert environment with nitrogen (remedied wood) or with water vapor shots (Finnish heat-treated lumber). The wood takes on an attractive brown color and ends up being hydrophobic as well as extremely resistant to fungal or insect attacks. However, the heat compromises these timbers a little, which can not be used for architectural purposes (mostly in exterior siding, parquet, and terrace boards).
The so-called homeothermic process does not have this disadvantage: the timber is only heated up to 130 ° C, with an immersion in a mixture based on linseed oil and grease by-products, which permits a deep impregnation. This likewise makes sure a longer resistance to greying and also does not require regular maintenance. The procedure makers have begun to market it in France: 3 makers in the timber industry have already bought it, as well as others remain in the pipe. The current Wood-Protect procedure patented by Lapeyre and INRA-INPT in Toulouse is of the same kind, with impregnation by autoclave and afterwards by soaking at 140 ° C in a combination of grease by-products and acetic acid.

High-temperature treatments make the wood wholly water resistant and also fungi resistant.
The wood is given a temperature level between 210 ° C and 250 ° C in special stoves. It after that alters color to become darker. The main disadvantage is that it sheds its stamina. It can then only be used for cladding or floor covering.
Oleothermy is a treatment that includes 3 stages: heating to 130 ° C in a rapeseed oil bathroom, cooling down in a linseed oil bathroom, and also drying out. Considering that the home heating temperature is less than the previous method, the wood is much less brittle.
Studies have actually revealed that homeothermic heating is valuable when done after boron treatment. Boron has anti-inflammatory residential or commercial properties. The issue is that it is not immune to cleaning. Thus, the homeothermic makes it feasible to take care of the molecule as well as make the timber extra immune to fires, water, and shocks. For more information concerning this technique, right here is a doctoral thesis that was done on the subject.
Oils, Discolorations, and Paints
The durability of certain species such as oak and chestnut is primarily as a result of their high tannin web content. Nonetheless, these are gradually washed out by rainwater, which is somewhat acidic. Like various other varieties, oak and chestnut, for that reason, need surface defense. Linseed oil with a little turpentine included – to be utilized in hot weather (it permeates better) – is timeless and also low-cost protection, water-repellent, and hold-ups greying.
Organic wood stains, which are colored yet show the timber grain, provide far better defense against UV rays thanks to the pigments they include. However, they should be restored every 3 to 5 years for the south exteriors as well as every 8 to one decade for the north exteriors. Unlike paints, they do not require sanding before revival (a brush stroke suffices to get rid of the pigment dust). As for natural lacquer paints, they provide more durable defense considering that they have fillers (especially chalk) that develop an entire screen against UV rays. It’s a little bit like sun creams; the security depends upon the screen’s high quality and also the exposure. Scenic Design Basic Furniture Ground Plan
Surface area Protection
To boost the sturdiness of exterior wood normally, go with a tarnish, for example, a combination of linseed oil and turpentine. Some commercially readily available timber discolorations are colored and give slight UV protection. The advantage of this method is that no sanding is required.
For also far better defense, use organic lacquer paint. It will offer ideal protection against ultraviolet rays– prefer microporous paints containing chalk fillers to allow the wood take a breath.
Safeguarding outside wood normally can be made with a protective stain or warm treatment. The choice of technique relies on the attributes that you wish to customize. If particular wood varieties can be made use of without defense, they have to be tarnished after a particular period since the safety tannins will have vanished. If you do refrain this, you will have to have an expert wetness therapy.
Securing Wood from Water
Safeguarding timber from water is an essential feature of an outside surface before any ornamental facet. It is recommended to save the material with paint, varnish, stain, saturator, or oil. Indeed, it is necessary to achieve an actual barrier effect, which need to be waterproof if the timber is not to deteriorate as well promptly.
This makes it possible to protect all-natural, strong, raw, or veneered wood basically in time. It is safeguarded to keep for many years when faced with the various climatic aggressiveness experienced. It is durably protected from moisture, rain, poor climate, light, sun, as well as ultraviolet rays, making it age too soon. Scenic Design Basic Furniture Ground Plan
Remain Naturally Permeable to Moisture
Remain wetness permeableStaying naturally permeable to smoke is very vital. Wood is comprised of plant fibers that have an excellent fondness with water. It is, for that reason, a breakable material that remains easily absorptive to water. It stays especially sensitive to various fluids that penetrate it.
Timber absorbs really rapidly the moisture that is present in the ambient atmosphere. It absorbs water before naturally releasing it because it is a hygroscopic product. It stays in continuous balance with its environment, whatever the moisture web content.
These various humidity variants go to the origin of the normal dimensional makeovers of timber. They have the impact of triggering deformations that can sometimes be considerable. It functions by swelling if the air is too moist. It reduces when the ambience becomes drier.
Rain, showers, electrical storms, and also various other negative climate that are in contact with the wood can create the appearance of unpleasant spots, touches, trickles, and halos. Moisture, seepage, condensation, and water vapor are additionally responsible for the premature aging of wood over the years. Scenic Design Basic Furniture Ground Plan
Do Not Avoid Exchanges with The Outside World.
Do not protect against exchanges with the outdoors not prevent interactions with the exterior; it needs to be appreciated. When you want to shield the wood, a water-repellent product must be related to avoid water from permeating it. It must be made certain that it is not fertilized by wetness if it is to last over the long-term.
A timber therapy product can just be perfectly ideal if it values the different moisture exchanges. The timber should be able to remain to manage itself with its atmosphere. It is essential to ensure that the film continues to be sufficiently micro-porous to ensure a great exchange performance.
On the other hand, impermeability as well as water rigidity ought to not be perplexed, which are extremely different notions. Waterproofing has to be prohibited when it comes to timber protection. Making a wood totally watertight may trigger the material to rot in the long term.
Gas exchange, which controls the moisture web content in the timber’s pores, must never ever be protected against. A wood paint need to permit the substratum to take a breath without ever quiting the internal evacuation to the outside. It needs to simply stop water from permeating the heart of the timber, not to change or weaken it.
Picking a Right Timber Treatment Product
Picking a wood treatment picking the ideal timber therapy product is important to shield wood successfully with time. There are various sorts of products that can properly maintaining this product. One can use a product that penetrates deeply, such as oil, impregnation, or saturator.
A passing through treatment offers extra reliable protection than an item that deposits a movie on the surface area, such as paint, varnish, or sealant. While a film-forming product may appear valuable originally, this is not constantly the situation in the lengthy term.
They can finish up cracking, flaking, cracking, or peeling off over the years. Infiltration, water, or moisture permeates the product, which becomes improperly insulated. It is after that important to sand or strip the surface of the timber to bare it again to be preserved.
Silicones are widely made use of in wood waterproofing items. These damaging materials ought to be prevented similarly as oil solvents, which are still existing in many products. They are not harmless to the individual, the environment, or nature. It is far better to pick a bio-sourced product of plant beginning that follows this natural material.

Keep Frequently for Adequate Defense.
Keep completely security keep regularly for an ample protection, stays a procedure that should not be forgotten to carry out. No matter the sort of waterproofing picked to preserve the timber, it is necessary to keep it on a regular basis to make sure that the defense continues to be adequately efficient in time.
Tedious preparation, sanding, gritting, or removing of the surface can be avoided utilizing an oil, saturator, or impregnation. They have the particularity of safeguarding the product throughout its mass without developing a film externally that can exfoliate later.
A waterproofing agent’s feature is to shield the wood from spots, marks, rings, and day-to-day damage. It is usually connected with an anti UV agent that will certainly protect against the timber from becoming as well grey in the future. It hence restricts the sensation of swelling or shrinking.
A non-film-forming water repellent has lots of advantages for maintaining a wood surface. It is very effective against negative weather condition thanks to an obstacle impact. Likewise, it stays very efficient in nurturing the wood in all its depth to the product’s actual heart. It also shields the assistance from light, sun, as well as ultraviolet rays.
