Exterior wood has 2 primary opponents: UV (ultraviolet rays from sunshine) and also humidity. The first causes a type of shallow melt – like on our skin, leading to tiny cracks and greying. Nothing significant, the damage is mainly visual, as well as the wood is not impacted in depth. Online Floor Plan Custom Size Furniture
Moisture presents a lot more serious issues: if rain does not run off or does not vaporize quickly, if the wood continues to be in contact with the ground or if the dampness can rise by capillary activity, the moisture material of the wood will certainly permit the installment of lignivorous fungi that are precursors to rot as well as support strikes by wood-eating bugs. Can chemical preservative treatments be stayed clear of?
Durable Species, without Sapwood
Some naturally long lasting varieties from our areas can be utilized without therapy when the wood is laid up and down (risk class 3) as well as permits excellent water drain (cladding, windows, shutters): in particular Douglas, larch, chestnut, oak, as well as grasshopper. Just the last 3 species are suggested when the timber is laid horizontally (balcony or terrace boards) or in contact with the ground (danger course 4). These woods need to additionally be picked as well as cut in such a method as to eliminate the sapwood, the outer part of the trunk abundant in sugars, which attracts wood-eating insects.

What Are the Benefits of Protecting Your Timber?
Embellishes and also Shields
Beyond maintaining the aesthetic element gradually, making use of a wood oil or a saturator in the protection of wood will revive its original color as well as improve the grain of the timber while keeping its natural appearance.
Stabilizes the Timber
Fueling oil a wood allows boosting its dimensional stability durably, thus decreasing the sensations of contortion (tiling, swelling, as well as contraction), fracturing, or surface splitting.
All-natural and Ecological
Choosing an “Oleobois” safety oil implies selecting a healthy and balanced and eco-friendly solution; the structure excludes fungicides, turpentine, as well as any oil derivatives frequently utilized (paraffin, white spirit, …).
Easy and also Economical Maintenance
Maintenance is very easy since as soon as oiled; timber does not require to be removed or sanded prior to remodelling: a cleansing with black soap adhered to by an easy re-oiled surface area is enough. Online Floor Plan Custom Size Furniture
Greying of The Wood
What Is Wood Graying?
Wood is a product almost comprised of polysaccharides (cellulose and also hemicelluloses) as well as lignins that will certainly be broken down under ultraviolet photons’ activity. This photodegradation of the lignins, which is additionally accentuated in the presence of water, is responsible for the development of the color of the wood. Greying is observed on the timber made use of outdoors without any physical security and UV defense. This sensation triggers an adjustment in the original color of the raw timber with time, which has a tendency to become grey.
What Are the Effects of Greying?
Greying or graying, which is a really surface sensation, only influences the wood framework’s visual appeals. It does not indicate a structural modification and also does not affect the strength of the material. The look of this phenomenon is restricted to the surface area of the timber. The loss of structural longevity (which can go as far as the destroy of the material) is, for its component, as a result of assaults of biological beginning that impact the wood in its mass.
Is it possible to stay clear of the greying of the timber without keeping it?
NO – Without finishing products and also without maintenance, it would be imaginary to claim to be able to stop the wood from greying.
Will the application of a coating stop the timber from transforming grey?
YES – If this application is made routinely, it is possible to prevent this phenomenon. The hydrophobic nature of the oil strongly limits the timber’s fondness for water and consequently postpones its action. Online Floor Plan Custom Size Furniture
Remedied and also Thermo-Oiled Wood
Numerous current processes have actually made it possible to improve the toughness and dimensional stability of other species dramatically: these are high-temperature warm treatments (210 to 250 ° C )in numerous stages, executed in special furnaces, either under an inert environment with nitrogen (remedied timber) or with water vapor injections (Finnish heat-treated lumber). The wood takes on an attractive brown shade as well as ends up being hydrophobic and extremely resistant to fungal or insect strikes. Nonetheless, the high temperature compromises these timbers a little, which can not be utilized for structural functions (generally in siding, parquet, as well as balcony boards).
The supposed homeothermic process does not have this downside: the timber is just heated up to 130 ° C, with an immersion in a mix based upon linseed oil and also vegetable oil by-products, which enables a deep impregnation. This additionally ensures a longer resistance to greying and also does not require regular upkeep. The process creators have actually begun to market it in France: 3 manufacturers in the timber industry have already bought it, as well as others remain in the pipe. The recent Wood-Protect procedure patented by Lapeyre as well as INRA-INPT in Toulouse is of the same type, with impregnation by autoclave and after that by saturating at 140 ° C in a combination of grease derivatives as well as acetic acid.

High-temperature treatments make the wood completely waterproof and also fungi resistant.
The timber is given a temperature in between 210 ° C and also 250 ° C in unique ovens. It then alters color to become darker. The major drawback is that it sheds its toughness. It can then just be utilized for cladding or flooring.
Oleothermy is a therapy that contains 3 phases: home heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bath, and also drying. Considering that the home heating temperature level is less than the previous method, the wood is much less breakable.
Researches have actually revealed that homeothermic heating is valuable when done after boron therapy. Boron has anti-inflammatory residential properties. The trouble is that it is not immune to washing. Hence, the homeothermic makes it possible to take care of the molecule as well as make the timber extra resistant to flames, water, as well as shocks. To get more information about this technique, below is a doctoral thesis that was done on the subject.
Oils, Spots, and also Paints
The durability of specific types such as oak as well as chestnut is mostly because of their high tannin content. Nevertheless, these are gradually rinsed by rainwater, which is a little acidic. Like various other species, oak as well as chestnut, consequently, require surface area protection. Linseed oil with a little turpentine added – to be used in hot weather (it penetrates far better) – is classic and also inexpensive protection, water-repellent, and delays greying.
Organic timber stains, which are colored but reveal the wood grain, give better security against UV rays thanks to the pigments they contain. Nonetheless, they should be renewed every 3 to 5 years for the south exteriors and also every 8 to ten years for the north facades. Unlike paints, they do not need sanding before revival (a brush stroke is enough to remove the pigment dust). When it comes to organic lacquer paints, they provide even more resilient protection because they consist of fillers (specifically chalk) that develop a whole screen against UV rays. It’s a little bit like sun creams; the security depends upon the display’s high quality and also the exposure. Online Floor Plan Custom Size Furniture
Surface area Security
To enhance the resilience of outdoor wood naturally, go with a tarnish, for example, a blend of linseed oil as well as turpentine. Some readily readily available timber spots are colored and supply slight UV protection. The benefit of this technique is that no sanding is called for.
For even better defense, use natural lacquer paint. It will certainly give ideal security against ultraviolet rays– favor microporous paints having chalk fillers to let the wood take a breath.
Safeguarding outside timber naturally can be finished with a safety tarnish or heat treatment. The choice of method relies on the characteristics that you desire to customize. If particular timber varieties can be utilized without protection, they need to be stained after a certain duration since the safety tannins will have disappeared. If you do not do this, you will need to have a professional moisture therapy.
Protecting Wood from Water
Securing timber from water is an essential function of an outside coating before any kind of attractive element. It is suggested to save the material with paint, varnish, discolor, saturator, or oil. Without a doubt, it is important to attain an actual obstacle impact, which must be water-proof if the timber is not to deteriorate also rapidly.
This makes it possible to preserve all-natural, solid, raw, or veneered timber basically with time. It is protected to maintain for several years despite the numerous climatic aggressiveness ran into. It is durably protected from humidity, rainfall, negative climate, light, sun, as well as ultraviolet rays, making it age too soon. Online Floor Plan Custom Size Furniture
Continue To Be Naturally Permeable to Wetness
Stay dampness permeableStaying normally permeable to smoke is very crucial. Wood is made up of plant fibers that have a superb fondness with water. It is, as a result, a delicate material that continues to be conveniently permeable to water. It stays specifically conscious different fluids that permeate it.
Wood absorbs extremely rapidly the humidity that is present in the ambient atmosphere. It absorbs water prior to normally launching it due to the fact that it is a hygroscopic product. It remains in constant stability with its setting, whatever the moisture content.
These different moisture variants are at the origin of the usual dimensional transformations of wood. They have the result of causing contortions that can sometimes be significant. It functions by swelling if the air is as well moist. It diminishes when the environment comes to be drier.
Rain, showers, thunderstorms, as well as various other bad weather that touch with the timber can create the appearance of undesirable stains, streaks, drips, as well as halos. Moisture, seepage, condensation, and water vapor are likewise responsible for the early aging of wood over the years. Online Floor Plan Custom Size Furniture
Do Not Protect against Exchanges with The Outside World.
Do not prevent exchanges with the outdoors not prevent interactions with the outside; it has to be appreciated. When you wish to safeguard the timber, a water-repellent item needs to be related to stay clear of water from permeating it. It should be made sure that it is not fertilized by wetness if it is to last over the long term.
A timber treatment product can only be completely ideal if it appreciates the different moisture exchanges. The timber needs to be able to continue to control itself with its atmosphere. It is important to make sure that the film continues to be completely micro-porous to assure a great exchange efficiency.
On the other hand, impermeability and water rigidity ought to not be puzzled, which are extremely various concepts. Waterproofing needs to be restricted when it comes to timber security. Making a wood totally watertight may trigger the product to rot in the long term.
Gas exchange, which manages the wetness material in the wood’s pores, have to never ever be prevented. A wood paint must allow the substrate to take a breath without ever before quiting the interior discharge to the exterior. It needs to just protect against water from permeating the heart of the timber, not to alter or weaken it.
Selecting a Right Wood Treatment Product
Choosing a timber therapy selecting the right timber therapy item is necessary to shield timber efficiently over time. There are different types of products that can effectively preserving this material. One can make use of an item that permeates deeply, such as oil, impregnation, or saturator.
A permeating therapy offers more effective protection than a product that deposits a film on the surface area, such as paint, varnish, or sealant. While a film-forming item might seem useful initially, this is not constantly the situation in the long term.
Without a doubt, they can end up splitting, flaking, breaking, or peeling throughout the years. Infiltration, water, or humidity penetrates the material, which becomes inadequately shielded. It is after that vital to sand or strip the surface of the timber to bare it again to be maintained.
Silicones are commonly utilized in timber waterproofing products. These hazardous materials ought to be stayed clear of similarly as oil solvents, which are still existing in numerous products. They are not safe to the user, the atmosphere, or nature. It is far better to choose a bio-sourced item of plant origin that is consistent with this natural material.

Maintain Routinely for Adequate Security.
Keep for good security keep frequently for an ample defense, remains a procedure that must not be neglected to execute. Despite the type of waterproofing chosen to protect the timber, it is necessary to preserve it on a regular basis to ensure that the security stays completely reliable in time.
Tiresome preparation, fining sand, gritting, or removing of the surface area can be prevented utilizing an oil, saturator, or impregnation. They have the particularity of shielding the material throughout its mass without producing a film on the surface that can exfoliate later.
A waterproofing representative’s feature is to safeguard the wood from stains, marks, rings, as well as everyday damage. It is usually related to an anti UV representative that will certainly stop the wood from becoming too grey over time. It therefore limits the phenomenon of swelling or contraction.
A non-film-forming water repellent has several benefits for preserving a wood surface. It is extremely reliable versus negative climate thanks to an obstacle result. Additionally, it stays extremely efficient in nourishing the timber in all its depth to the product’s actual heart. It additionally secures the support from light, sunlight, and also ultraviolet rays. Online Floor Plan Custom Size Furniture
