Outside timber has two major enemies: UV (ultraviolet rays from sunlight) and also moisture. The first causes a type of superficial melt – like on our skin, leading to tiny fractures as well as greying. Nothing significant, the damages is mostly visual, and the wood is not influenced extensive. Plan Toys Chalet With Furniture
Wetness positions a lot more extreme troubles: if rain does not escape or does not vaporize rapidly, if the wood stays in contact with the ground or if the moisture can climb by capillary activity, the wetness web content of the timber will certainly allow the setup of lignivorous fungis that are precursors to rot and also favor attacks by wood-eating bugs. Can chemical preservative treatments be stayed clear of?
Resilient Types, without Sapwood
Some naturally sturdy types from our areas can be used without treatment when the wood is laid vertically (risk course 3) and also enables excellent water drainage (cladding, home windows, shutters): particularly Douglas, larch, chestnut, oak, and also cicada. Just the last three species are recommended when the timber is laid horizontally (porch or terrace boards) or in contact with the ground (danger course 4). These woods have to likewise be picked and cut in such a way as to remove the sapwood, the outer part of the trunk rich in sugars, which brings in wood-eating bugs. Plan Toys Chalet With Furniture
What Are the Benefits of Shielding Your Wood?
Embellishes and also Protects
Past preserving the visual facet over time, utilizing a timber oil or a saturator in the protection of wood will revive its initial shade and also improve the grain of the timber while preserving its all-natural appearance.
Stabilizes the Timber
Oiling a timber allows boosting its dimensional stability durably, therefore lowering the phenomena of deformation (tiling, swelling, as well as shrinking), breaking, or surface area splitting.
All-natural and also Ecological
Picking an “Oleobois” protective oil means selecting a healthy and balanced as well as eco-friendly service; the composition omits fungicides, turpentine, and any kind of petroleum by-products often made use of (paraffin, white spirit, …).
Easy and also Economical Upkeep
Upkeep is easy because once oiled; timber does not need to be stripped or fined sand before improvement: a cleansing with black soap complied with by a straightforward re-oiled surface area is enough. Plan Toys Chalet With Furniture
Greying of The Timber
What Is Timber Graying?
Timber is a material virtually comprised of polysaccharides (cellulose and hemicelluloses) as well as lignins that will be broken down under ultraviolet photons’ activity. This photodegradation of the lignins, which is likewise accentuated in the existence of water, is in charge of the evolution of the color of the wood. Greying is observed on the timber utilized outdoors with no physical defense as well as UV defense. This sensation causes a change in the original shade of the raw wood in time, which has a tendency to end up being grey.
What Are the Consequences of Greying?
Greying or graying, which is an extremely surface phenomenon, only affects the wooden framework’s visual appeals. It does not show an architectural alteration and also does not influence the strength of the material. The appearance of this sensation is restricted to the surface of the wood. The loss of structural resilience (which can go as far as the destroy of the material) is, for its part, because of attacks of organic origin that affect the wood in its mass.
Is it feasible to prevent the greying of the timber without maintaining it?
NO – Without finishing items and also without upkeep, it would certainly be imaginary to claim to be able to stop the wood from greying.
Will the application of a surface stop the timber from transforming grey?
YES – If this application is made on a regular basis, it is feasible to avoid this phenomenon. The hydrophobic nature of the oil highly restricts the wood’s affinity for water and also as a result delays its action. Plan Toys Chalet With Furniture
Corrected and Thermo-Oiled Timber
Several recent processes have made it feasible to boost the sturdiness as well as dimensional security of various other varieties dramatically: these are high-temperature heat therapies (210 to 250 ° C )in a number of phases, performed in unique heaters, either under an inert environment with nitrogen (remedied timber) or with water vapor shots (Finnish heat-treated lumber). The wood tackles a lovely brown shade and also becomes hydrophobic as well as really immune to fungal or insect assaults. The high temperature level compromises these woods a little, which can not be utilized for structural objectives (mainly in home siding, parquet, and also terrace boards).
The so-called homeothermic process does not have this disadvantage: the timber is just heated up to 130 ° C, with an immersion in a blend based upon linseed oil as well as grease by-products, which allows a deep impregnation. This additionally guarantees a longer resistance to greying and does not need routine upkeep. The procedure developers have started to market it in France: three producers in the timber market have currently bought it, as well as others remain in the pipe. The recent Wood-Protect process 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 grease by-products and acetic acid.

High-temperature treatments make the wood entirely water resistant and also fungi immune.
The wood is brought to a temperature in between 210 ° C as well as 250 ° C in unique ovens. It then alters color to become darker. The major disadvantage is that it loses its strength. It can then just 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 down in a linseed oil bath, as well as drying out. Considering that the heating temperature is less than the previous method, the timber is less weak.
Researches have shown that homeothermic home heating is useful when done after boron therapy. Boron has anti-inflammatory homes. The trouble is that it is not resistant to washing. Thus, the homeothermic makes it possible to fix the particle and make the timber extra resistant to fires, water, and shocks. For more information regarding this method, below is a doctoral thesis that was done on the subject.
Oils, Discolorations, and Paints
The resilience of specific types such as oak and also chestnut is generally as a result of their high tannin content. Nevertheless, these are progressively rinsed by rainwater, which is a little acidic. Like other types, oak as well as chestnut, as a result, call for surface area defense. Linseed oil with a little turpentine added – to be used in hot weather (it penetrates much better) – is traditional and affordable security, water-repellent, as well as delays greying.
Organic timber discolorations, which are colored yet reveal the wood grain, give better protection against UV rays thanks to the pigments they consist of. Nonetheless, they ought to be renewed every 3 to 5 years for the south exteriors and every 8 to ten years for the north exteriors. Unlike paints, they do not require sanding prior to renewal (a brush stroke is enough to get rid of the pigment dust). As for natural lacquer paints, they offer more durable protection because they have fillers (specifically chalk) that develop an entire display against UV rays. It’s a bit like sun creams; the safety depends on the screen’s quality and also the exposure. Plan Toys Chalet With Furniture
To improve the sturdiness of outside wood normally, go with a tarnish, for example, a mix of linseed oil and turpentine. Some commercially readily available wood discolorations are colored and also provide mild UV security. The benefit of this method is that no sanding is needed.
For also better defense, apply organic lacquer paint. It will give optimum defense versus ultraviolet rays– favor microporous paints consisting of chalk fillers to let the wood breathe.
Shielding outside wood naturally can be made with a protective discolor or warmth therapy. The option of method depends upon the characteristics that you want to customize. If specific wood types can be utilized without defense, they have to be stained after a specific duration since the safety tannins will have gone away. If you do refrain this, you will certainly need to have a specialist wetness therapy.
Securing Timber from Water
Safeguarding wood from water is a necessary feature of an outside finish before any type of attractive facet. It is suggested to conserve the product with paint, varnish, tarnish, saturator, or oil. It is necessary to achieve a real obstacle effect, which should be water resistant if the timber is not to weaken too swiftly.
This makes it possible to preserve natural, solid, raw, or veneered timber practically over time. It is secured to maintain for years in the face of the different weather aggressiveness encountered. It is durably protected from moisture, rainfall, poor weather condition, light, sunlight, and ultraviolet rays, making it age prematurely. Plan Toys Chalet With Furniture
Remain Naturally Permeable to Dampness
Remain dampness permeableStaying normally permeable to smoke is really crucial. Timber is comprised of plant fibers that have an outstanding affinity with water. It is, consequently, a delicate product that remains conveniently permeable to water. It stays specifically conscious different fluids that penetrate it.
Wood soaks up extremely rapidly the moisture that is present in the ambient atmosphere. It absorbs water before naturally launching it because it is a hygroscopic product. It continues to be in continuous equilibrium with its setting, whatever the wetness web content.
These different moisture variations are at the origin of the typical dimensional improvements of timber. They have the result of creating contortions that can in some cases be significant. It functions by swelling if the air is also moist. It diminishes when the environment ends up being drier.
Rainfall, showers, electrical storms, and also various other poor weather that touch with the wood can create the appearance of undesirable spots, streaks, drips, as well as halos. Dampness, infiltration, condensation, and also water vapor are also in charge of the premature aging of wood throughout the years. Plan Toys Chalet With Furniture
Do Not Prevent Exchanges with The Outdoors.
Do not avoid exchanges with the outdoors not stop interactions with the outside; it has to be appreciated. When you intend to shield the wood, a water-repellent item must be put on avoid water from penetrating it. It must be made sure that it is not impregnated by wetness if it is to last over the long term.
A timber therapy product can only be perfectly suitable if it values the various wetness exchanges. The wood must have the ability to continue to manage itself with its atmosphere. It is necessary to ensure that the film continues to be adequately micro-porous to ensure a great exchange performance.
On the other hand, impermeability and water rigidity should not be confused, which are very various concepts. Waterproofing needs to be banned when it comes to timber protection. Making a timber totally watertight may cause the product to rot in the long-term.
Gas exchange, which manages the moisture content in the timber’s pores, must never be avoided. A wood paint must permit the substratum to breathe without ever before stopping the internal discharge to the exterior. It has to just prevent water from permeating the heart of the timber, not to alter or deteriorate it.
Choosing a Right Wood Treatment Product
Picking a timber treatment choosing the right timber therapy product is necessary to secure timber effectively gradually. There are various kinds of items that are capable of effectively maintaining this product. One can utilize a product that penetrates deeply, such as oil, impregnation, or saturator.
A permeating therapy offers extra effective protection than an item that transfers a film externally, such as paint, varnish, or sealer, for example. Undoubtedly, while a film-forming product might seem useful originally, this is not constantly the situation in the long-term.
Indeed, they can wind up fracturing, flaking, splitting, or peeling for many years. Infiltration, water, or moisture permeates the material, which becomes inadequately shielded. It is after that important to sand or strip the surface of the wood to bare it once more to be preserved.
Silicones are widely made use of in timber waterproofing items. These damaging substances should be avoided similarly as petroleum solvents, which are still existing in many products. They are not safe to the individual, the environment, or nature. It is much better to pick a bio-sourced product of plant beginning that follows this all-natural product.

Keep Frequently for Adequate Protection.
Preserve completely security preserve on a regular basis for an appropriate defense, stays an operation that needs to not be forgotten to execute. No matter the kind of waterproofing chosen to preserve the wood, it is essential to keep it frequently so that the security continues to be completely reliable with time.
Tiresome prep work, fining sand, gritting, or removing of the surface can be stayed clear of 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 flake off later.
A waterproofing agent’s feature is to safeguard the wood from spots, marks, rings, and daily damage. It is generally connected with an anti UV representative that will certainly stop the wood from ending up being too grey over time. It thus restricts the phenomenon of swelling or shrinkage.
A non-film-forming water repellent has lots of advantages for maintaining a wood surface area. It is really efficient against negative climate thanks to an obstacle effect. It continues to be very reliable in nurturing the wood in all its depth to the product’s actual heart. It also secures the assistance from light, sunlight, and ultraviolet rays.
