Exterior wood has two primary enemies: UV (ultraviolet rays from sunshine) as well as humidity. The first causes a sort of superficial melt – like on our skin, causing little cracks and greying. Absolutely nothing dramatic, the damage is mainly visual, and the wood is not affected extensive. Free Room Plan Furniture
Moisture presents a lot more severe problems: if rainwater does not run or does not evaporate quickly, if the timber continues to be in contact with the ground or if the wetness can rise by capillary activity, the moisture content of the timber will certainly permit the setup of lignivorous fungi that are forerunners to rot and favor strikes by wood-eating pests. Can chemical preservative treatments be avoided?
Long lasting Variety, without Sapwood
Some normally sturdy types from our regions can be utilized without treatment when the wood is laid vertically (risk class 3) and enables great water drainage (cladding, windows, shutters): particularly Douglas, larch, chestnut, oak, and grasshopper. Just the last 3 varieties are suggested when the wood is laid flat (veranda or terrace boards) or in contact with the ground (threat class 4). These woods have to likewise be chosen as well as cut in such a way as to eliminate the sapwood, the peripheral part of the trunk abundant in sugars, which draws in wood-eating insects.

What Are the Advantages of Shielding Your Wood?
Embellishes and Safeguards
Beyond keeping the visual facet gradually, making use of a timber oil or a saturator in the defense of timber will certainly revitalize its original color as well as enhance the grain of the wood while keeping its all-natural appearance.
Stabilizes the Timber
Fueling oil a wood permits enhancing its dimensional security durably, hence reducing the phenomena of deformation (tiling, swelling, as well as contraction), breaking, or surface area splitting.
Natural as well as Ecological
Selecting an “Oleobois” protective oil indicates picking a healthy as well as environmentally friendly option; the composition leaves out fungicides, turpentine, as well as any kind of oil derivatives often used (paraffin, white spirit, …).
Easy and also Economical Maintenance
Upkeep is easy because when fueled oil; timber does not require to be stripped or fined sand before restoration: a cleansing with black soap adhered to by a basic re-oiled surface area suffices. Free Room Plan Furniture
Greying of The Timber
What Is Wood Graying?
Wood is a material almost composed of polysaccharides (cellulose and hemicelluloses) and lignins that will certainly be degraded under ultraviolet photons’ action. This photodegradation of the lignins, which is also emphasized in the presence of water, is in charge of the development of the color of the timber. Greying is observed on the timber utilized outdoors with no physical security as well as UV protection. This sensation creates a change in the original color of the raw wood in time, which often tends to come to be gray.
What Are the Consequences of Greying?
Greying or graying, which is a really surface sensation, only influences the wooden structure’s aesthetics. It does not show a structural change and does not affect the solidity of the material. The look of this phenomenon is restricted to the surface of the wood. The loss of structural durability (which can reach the spoil of the material) is, for its component, because of assaults of organic origin that influence the timber in its mass.
Is it possible to prevent the greying of the timber without keeping it?
NO – Without finishing products as well as without upkeep, it would certainly be imaginary to declare to be able to avoid the timber from greying.
Will the application of a surface stop the timber from turning grey?
YES – If this application is made frequently, it is possible to avoid this sensation. The hydrophobic nature of the oil strongly restricts the timber’s fondness for water and also for that reason delays its activity. Free Room Plan Furniture
Corrected and Thermo-Oiled Timber
Several current procedures have actually made it feasible to boost the durability as well as dimensional stability of various other types significantly: these are high-temperature warm treatments (210 to 250 ° C )in numerous stages, executed in unique heating systems, either under an inert atmosphere with nitrogen (rectified wood) or with water vapor shots (Finnish heat-treated lumber). The wood takes on a beautiful brownish color and becomes hydrophobic and also extremely resistant to fungal or insect assaults. Nevertheless, the heat damages these timbers a little, which can not be utilized for structural purposes (mainly in exterior siding, parquet, as well as terrace boards).
The so-called homeothermic procedure does not have this negative aspect: the wood is just warmed up to 130 ° C, with an immersion in a mixture based on linseed oil as well as vegetable oil derivatives, which permits a deep impregnation. This additionally ensures a much longer resistance to greying as well as does not call for regular maintenance. The procedure makers have actually begun to market it in France: three suppliers in the wood market have already bought it, and others remain in the pipeline. The current Wood-Protect procedure patented by Lapeyre as well as INRA-INPT in Toulouse is of the same kind, with impregnation by autoclave and after that by soaking at 140 ° C in a mix of vegetable oil by-products and acetic acid.

High-temperature treatments make the wood entirely water-proof and fungus immune.
The timber is offered a temperature level in between 210 ° C as well as 250 ° C in special stoves. It after that alters color to become darker. The main downside is that it sheds its stamina. It can then only be made use of for cladding or floor covering.
Oleothermy is a treatment that consists of 3 stages: home heating to 130 ° C in a rapeseed oil bathroom, cooling down in a linseed oil bath, and drying. Considering that the heating temperature is less than the previous method, the wood is much less weak.
Studies have actually revealed that homeothermic home heating is valuable when done after boron treatment. Boron has anti-inflammatory homes. The issue is that it is not immune to washing. Thus, the homeothermic makes it feasible to take care of the particle and also make the timber extra resistant to fires, water, and also shocks. To read more concerning this technique, below is a doctoral thesis that was done on the topic.
Oils, Stains, as well as Paints
The sturdiness of specific species such as oak and also chestnut is primarily due to their high tannin content. These are progressively washed out by rain, which is somewhat acidic. Like other species, oak as well as chestnut, for that reason, require surface defense. Linseed oil with a little turpentine included – to be used in hot weather (it penetrates far better) – is timeless and also affordable security, water-repellent, as well as hold-ups greying.
Organic timber stains, which are colored but show the wood grain, supply much better security versus UV rays thanks to the pigments they have. They must be restored every 3 to 5 years for the south facades and also every 8 to 10 years for the north exteriors. Unlike paints, they do not need sanding prior to renewal (a brush stroke is enough to eliminate the pigment dirt). As for organic lacquer paints, they offer even more long lasting defense since they have fillers (specifically chalk) that create a whole screen versus UV rays. It’s a bit like sun creams; the safety and security relies on the screen’s high quality and also the direct exposure. Free Room Plan Furniture
To improve the sturdiness of exterior timber naturally, select a stain, as an example, a mix of linseed oil and turpentine. Some readily available timber stains are tinted as well as offer minor UV protection. The advantage of this technique is that no sanding is required.
For also far better security, use organic lacquer paint. It will certainly offer optimal security against ultraviolet rays– favor microporous paints including chalk fillers to allow the wood take a breath.
Securing external wood normally can be done with a protective stain or warmth treatment. The choice of method relies on the attributes that you wish to modify. If specific timber species can be utilized without protection, they should be stained after a specific period since the protective tannins will certainly have gone away. If you do not do this, you will certainly need to have an expert wetness treatment.
Shielding Wood from Water
Securing timber from water is a crucial feature of an exterior finish before any kind of decorative element. It is suggested to save the product with paint, varnish, stain, saturator, or oil. It is crucial to attain an actual barrier impact, which should be water-proof if the timber is not to deteriorate as well promptly.
This makes it feasible to maintain all-natural, solid, raw, or veneered timber virtually with time. It is safeguarded to maintain for many years despite the different weather aggressiveness came across. It is durably maintained from humidity, rainfall, bad weather, light, sunlight, and also ultraviolet rays, making it age too soon. Free Room Plan Furniture
Remain Naturally Permeable to Dampness
Remain moisture permeableStaying naturally permeable to smoke is very vital. Wood is comprised of plant fibers that have a superb fondness with water. It is, therefore, a delicate product that remains quickly absorptive to water. It continues to be especially conscious numerous fluids that permeate it.
Wood soaks up very quickly the humidity that is present in the ambient ambience. It takes in water prior to normally launching it because it is a hygroscopic product. It remains in constant equilibrium with its setting, whatever the wetness material.
These various humidity variations are at the origin of the typical dimensional makeovers of timber. They have the impact of triggering deformations that can often be considerable. It functions by swelling if the air is as well damp. It reduces when the environment ends up being drier.
Rainfall, showers, thunderstorms, as well as other negative weather condition that are in contact with the timber can cause the appearance of unpleasant stains, touches, drips, and halos. Dampness, infiltration, condensation, and also water vapor are likewise in charge of the premature aging of wood over the years. Free Room Plan Furniture
Do Not Protect against Exchanges with The Outside World.
Do not avoid exchanges with the outdoors not stop interactions with the exterior; it has to be appreciated. When you wish to secure the timber, a water-repellent product has to be put on avoid water from penetrating it. It must be ensured that it is not fertilized by wetness if it is to last over the long term.
A wood treatment item can just be flawlessly suitable if it respects the various wetness exchanges. The timber should be able to continue to manage itself with its setting. It is necessary to ensure that the movie remains adequately micro-porous to ensure a good exchange performance.
On the other hand, impermeability and also water rigidity ought to not be perplexed, which are extremely different ideas. Waterproofing must be restricted in the case of timber defense. Making a wood totally watertight may cause the material to rot in the long term.
Gas exchange, which regulates the moisture web content in the timber’s pores, need to never ever be stopped. A timber paint need to permit the substratum to breathe without ever stopping the interior evacuation to the exterior. It needs to simply protect against water from passing through the heart of the timber, not to alter or degrade it.
Choosing a Right Wood Treatment Item
Picking a wood treatment picking the appropriate wood treatment product is important to shield wood efficiently in time. There are different sorts of items that are capable of effectively preserving this product. One can use an item that permeates deeply, such as oil, impregnation, or saturator.
A permeating therapy gives more efficient defense than an item that transfers a movie on the surface, such as paint, varnish, or sealer. While a film-forming item may seem useful originally, this is not always the instance in the long term.
They can finish up breaking, flaking, fracturing, or peeling off over the years. Seepage, water, or humidity permeates the product, which ends up being badly protected. It is after that vital to sand or strip the surface area of the wood to bare it again to be protected.
Silicones are extensively utilized in wood waterproofing items. These harmful materials ought to be prevented similarly as oil solvents, which are still existing in numerous items. They are not safe to the individual, the atmosphere, or nature. It is far better to select a bio-sourced product of plant origin that is consistent with this all-natural product.

Preserve Frequently for Adequate Security.
Keep forever protection keep consistently for an ample defense, continues to be a procedure that should not be forgotten to do. Despite the sort of waterproofing selected to maintain the wood, it is essential to maintain it regularly so that the defense stays adequately efficient with time.
Laborious prep work, fining sand, gritting, or removing of the surface can be avoided utilizing an oil, saturator, or impregnation. They have the particularity of shielding the product throughout its mass without producing a film externally that can flake off later.
A waterproofing agent’s function is to secure the wood from discolorations, marks, rings, and also daily damage. It is generally associated with an anti UV representative that will certainly avoid the wood from becoming too grey in the future. It therefore restricts the sensation of swelling or shrinkage.
A non-film-forming water repellent has several advantages for protecting a wooden surface. It is very reliable versus negative weather thanks to an obstacle impact. Likewise, it stays extremely effective in nourishing the wood in all its deepness to the product’s very heart. It likewise safeguards the assistance from light, sunlight, and also ultraviolet rays.
