Exterior wood has two major opponents: UV (ultraviolet rays from sunshine) and also humidity. The first causes a sort of superficial shed – like on our skin, causing small splits and also greying. Nothing remarkable, the damages is mainly aesthetic, and the wood is not impacted detailed. Open Floor Plan Layout Furniture Small
Dampness positions much more severe troubles: if rain does not escape or does not evaporate promptly, if the wood remains in contact with the ground or if the dampness can rise by capillary action, the moisture material of the timber will certainly enable the installation of lignivorous fungis that are precursors to rot and support attacks by wood-eating pests. Can chemical preservative therapies be prevented?
Resilient Variety, without Sapwood
Some normally sturdy varieties from our regions can be utilized without therapy when the wood is laid vertically (danger course 3) as well as allows excellent water drain (cladding, windows, shutters): specifically Douglas, larch, chestnut, oak, and grasshopper. Just the last 3 types are advised when the timber is laid flat (veranda or balcony boards) or touching the ground (danger class 4). These woods must additionally be selected and also cut in such a method as to get rid of the sapwood, the peripheral part of the trunk abundant in sugars, which brings in wood-eating insects.

What Are the Advantages of Safeguarding Your Wood?
Embellishes and also Shields
Past maintaining the aesthetic element in time, using a wood oil or a saturator in the protection of timber will certainly revive its original color and enhance the grain of the wood while preserving its natural appearance.
Maintains the Timber
Fueling oil a timber enables boosting its dimensional stability durably, hence decreasing the sensations of deformation (tiling, swelling, and shrinking), breaking, or surface splitting.
Natural and Ecological
Choosing an “Oleobois” safety oil means selecting a healthy and balanced and eco-friendly remedy; the structure leaves out fungicides, turpentine, as well as any oil by-products frequently made use of (paraffin, white spirit, …).
Easy and also Economical Upkeep
Maintenance is easy since once fueled oil; wood does not need to be stripped or fined sand before remodelling: a cleansing with black soap complied with by a basic re-oiled surface suffices. Open Floor Plan Layout Furniture Small
Greying of The Wood
What Is Timber Graying?
Wood is a product nearly comprised of polysaccharides (cellulose and also hemicelluloses) and also lignins that will certainly be deteriorated under ultraviolet photons’ activity. This photodegradation of the lignins, which is also highlighted in the presence of water, is accountable for the development of the shade of the wood. Greying is observed on the lumber used outdoors with no physical defense and also UV security. This phenomenon causes a change in the original color of the raw wood over time, which tends to end up being gray.
What Are the Consequences of Greying?
Greying or graying, which is a very superficial phenomenon, just impacts the wooden framework’s looks. It does not show an architectural change as well as does not affect the strength of the product. The look of this sensation is restricted to the surface area of the wood. The loss of architectural sturdiness (which can reach the ruin of the product) is, for its part, due to attacks of organic beginning that influence the timber in its mass.
Is it feasible to stay clear of the greying of the wood without keeping it?
NO – Without completing products as well as without upkeep, it would certainly be imaginary to assert to be able to prevent the timber from greying.
Will the application of a coating avoid the timber from turning grey?
YES – If this application is made consistently, it is possible to avoid this phenomenon. The hydrophobic nature of the oil strongly restricts the wood’s fondness for water as well as consequently delays its activity. Open Floor Plan Layout Furniture Small
Remedied and also Thermo-Oiled Timber
Numerous recent processes have actually made it possible to enhance the resilience as well as dimensional security of other types dramatically: these are high-temperature warm treatments (210 to 250 ° C )in a number of phases, performed in unique heaters, either under an inert ambience with nitrogen (corrected wood) or with water vapor injections (Finnish heat-treated lumber). The wood tackles a lovely brownish shade and comes to be hydrophobic and very immune to fungal or insect attacks. The high temperature deteriorates these woods a little, which can not be made use of for architectural functions (mainly in house siding, parquet, and balcony boards).
The so-called homeothermic procedure does not have this drawback: the wood is just heated up to 130 ° C, with an immersion in a combination based upon linseed oil as well as vegetable oil by-products, which permits a deep impregnation. This likewise makes sure a longer resistance to greying and also does not need routine maintenance. The procedure creators have actually started to market it in France: three manufacturers in the timber sector have actually currently bought it, and also others are in the pipe. The current Wood-Protect process patented by Lapeyre and 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 acetic acid.

High-temperature treatments make the timber entirely water-proof and fungi immune.
The wood is brought to a temperature between 210 ° C and 250 ° C in special ovens. It after that changes color to end up being darker. The major downside is that it sheds its stamina. It can then just be used for cladding or flooring.
Oleothermy is a therapy that includes 3 phases: home heating to 130 ° C in a rapeseed oil bathroom, cooling down in a linseed oil bathroom, and drying. Given that the heating temperature is less than the previous technique, the wood is much less brittle.
Researches have actually revealed that homeothermic heating is beneficial when done after boron treatment. Boron has anti-inflammatory properties. The trouble is that it is not resistant to washing. Therefore, the homeothermic makes it feasible to deal with the particle and also make the wood much more resistant to flames, water, and also shocks. To get more information regarding this technique, below is a doctoral thesis that was done on the topic.
Oils, Discolorations, as well as Paints
The durability of specific types such as oak and also chestnut is generally due to their high tannin material. These are gradually cleaned out by rain, which is somewhat acidic. Like various other species, oak as well as chestnut, consequently, call for surface defense. Linseed oil with a little turpentine added – to be made use of in heat (it permeates far better) – is traditional as well as affordable security, water-repellent, and also delays greying.
Organic wood stains, which are colored yet show the timber grain, provide far better defense against UV rays thanks to the pigments they have. They should be renewed every 3 to 5 years for the south facades and every 8 to 10 years for the north exteriors. Unlike paints, they do not require sanding before renewal (a brush stroke is enough to get rid of the pigment dust). When it comes to organic lacquer paints, they provide more sturdy security since they contain fillers (especially chalk) that form an entire display versus UV rays. It’s a bit like sun creams; the protection relies on the display’s high quality and the direct exposure. Open Floor Plan Layout Furniture Small
To improve the toughness of exterior wood normally, opt for a tarnish, for instance, a blend of linseed oil and also turpentine. Some readily readily available wood stains are tinted as well as supply minor UV security. The benefit of this approach is that no sanding is required.
For even far better protection, use natural lacquer paint. It will give optimum defense versus ultraviolet rays– prefer microporous paints including chalk fillers to allow the wood breathe.
Protecting outside timber normally can be performed with a safety tarnish or heat treatment. The option of approach relies on the attributes that you want to customize. If specific timber types can be utilized without defense, they must be stained after a specific period because the safety tannins will have gone away. If you do refrain from doing this, you will certainly have to have a professional moisture treatment.
Protecting Wood from Water
Protecting timber from water is an important function of an outside finish before any type of decorative element. It is advised to conserve the product with paint, varnish, discolor, saturator, or oil. Without a doubt, it is important to attain an actual obstacle effect, which need to be water resistant if the timber is not to degrade also swiftly.
This makes it possible to preserve all-natural, solid, raw, or veneered wood basically with time. It is secured to keep for years when faced with the different climatic aggressiveness ran into. It is durably preserved from moisture, rainfall, poor weather, light, sunlight, and ultraviolet rays, making it age prematurely. Open Floor Plan Layout Furniture Small
Continue To Be Normally Permeable to Wetness
Continue to be dampness permeableStaying normally absorptive to smoke is very important. Wood is comprised of plant fibers that have an exceptional fondness with water. It is, for that reason, a vulnerable product that stays quickly absorptive to water. It continues to be especially conscious various fluids that permeate it.
Wood takes in extremely rapidly the humidity that is present in the ambient environment. It takes in water prior to naturally releasing it because it is a hygroscopic product. It continues to be in continuous equilibrium with its setting, whatever the wetness content.
These various humidity variations are at the origin of the typical dimensional changes of wood. They have the impact of creating deformations that can sometimes be substantial. It works by swelling if the air is also humid. It shrinks when the ambience ends up being drier.
Rainfall, showers, thunderstorms, and other negative climate that touch with the wood can trigger the appearance of undesirable stains, streaks, trickles, and halos. Moisture, infiltration, condensation, as well as water vapor are also responsible for the early aging of wood over the years. Open Floor Plan Layout Furniture Small
Do Not Stop Exchanges with The Outdoors.
Do not prevent exchanges with the outside not protect against communications with the exterior; it needs to be respected. When you intend to protect the timber, a water-repellent product must be put on prevent water from permeating it. It should be made sure that it is not fertilized by dampness if it is to last over the long term.
A wood treatment product can only be perfectly suitable if it appreciates the various wetness exchanges. The timber must be able to remain to control itself with its environment. It is necessary to make certain that the movie continues to be sufficiently micro-porous to ensure a good exchange effectiveness.
On the other hand, impermeability and also water rigidity ought to not be puzzled, which are extremely various notions. Waterproofing has to be banned in the case of timber security. Making a timber totally watertight might create the material to rot in the long-term.
Gas exchange, which regulates the moisture content in the wood’s pores, need to never ever be avoided. A wood paint have to enable the substratum to take a breath without ever quiting the internal emptying to the exterior. It should just prevent water from passing through the heart of the timber, not to change or weaken it.
Choosing a Right Timber Therapy Item
Selecting a timber treatment selecting the best wood treatment item is essential to safeguard timber successfully in time. There are different sorts of items that can successfully protecting this material. One can make use of an item that permeates deeply, such as oil, impregnation, or saturator.
A passing through therapy supplies a lot more efficient protection than a product that transfers a film externally, such as paint, varnish, or sealant, as an example. Indeed, while a film-forming item may seem helpful at first, this is not always the instance in the long term.
Without a doubt, they can end up cracking, flaking, cracking, or peeling over the years. Seepage, water, or humidity passes through the material, which becomes improperly protected. It is after that essential to sand or strip the surface area of the timber to bare it once again to be preserved.
Silicones are extensively utilized in timber waterproofing items. These harmful materials should be prevented similarly as oil solvents, which are still present in many products. They are not harmless to the user, the atmosphere, or nature. It is better to choose a bio-sourced product of plant origin that follows this all-natural product.

Maintain Routinely for Adequate Defense.
Preserve permanently protection maintain frequently for an appropriate protection, continues to be an operation that must not be failed to remember to do. No matter the type of waterproofing chosen to preserve the timber, it is required to maintain it regularly so that the defense remains completely effective gradually.
Tiresome prep work, fining sand, gritting, or removing of the surface can be prevented utilizing an oil, saturator, or impregnation. They have the particularity of protecting the material throughout its mass without creating a movie externally that can exfoliate later.
A waterproofing agent’s function is to secure the timber from discolorations, marks, rings, and everyday damage. It is typically associated with an anti UV agent that will certainly protect against the timber from ending up being as well grey over time. It therefore restricts the phenomenon of swelling or shrinkage.
A non-film-forming water repellent has numerous benefits for preserving a wooden surface area. It is really effective versus bad weather condition thanks to an obstacle impact. Likewise, it remains very efficient in nourishing the timber in all its deepness to the product’s actual heart. It also secures the assistance from light, sunlight, as well as ultraviolet rays.
