Exterior timber has two major opponents: UV (ultraviolet rays from sunshine) and also humidity. The first causes a sort of superficial shed – like on our skin, leading to small splits and also greying. Nothing remarkable, the damages is mostly visual, and the timber is not impacted detailed.

Wetness presents much more extreme problems: if rain does not run off or does not vaporize promptly, if the wood stays touching the ground or if the wetness can rise by capillary action, the moisture material of the wood will certainly permit the installation of lignivorous fungi that are precursors to rot as well as support assaults by wood-eating bugs. Can chemical preservative treatments be avoided?
Sturdy Variety, without Sapwood
Some naturally resilient species from our areas can be used without treatment when the wood is laid vertically (risk class 3) and also enables good water drain (cladding, home windows, shutters): in particular Douglas, larch, chestnut, oak, as well as grasshopper. Only the last 3 species are advised when the wood is laid flat (veranda or terrace boards) or in contact with the ground (threat class 4). These timbers must also be selected and also cut in such a method regarding get rid of the sapwood, the peripheral part of the trunk abundant in sugars, which attracts wood-eating pests.

What Are the Advantages of Securing Your Timber?
Embellishes as well as Safeguards
Beyond preserving the visual element gradually, using a timber oil or a saturator in the security of timber will revive its initial color and also enhance the grain of the timber while preserving its natural look.
Maintains the Timber
Fueling oil a timber allows enhancing its dimensional security durably, hence reducing the phenomena of contortion (tiling, swelling, and also contraction), cracking, or surface splitting.
Natural as well as Ecological
Picking an “Oleobois” safety oil implies picking a healthy and balanced as well as environmentally friendly service; the make-up leaves out fungicides, turpentine, and also any petroleum derivatives frequently made use of (paraffin, white spirit, …).
Easy as well as Economical Maintenance
Maintenance is simple since when fueled oil; timber does not require to be stripped or sanded before restoration: a cleaning with black soap followed by a simple re-oiled surface area suffices. Furniture Plan Number Sheet Sets Architecture
Greying of The Timber
What Is Wood Graying?
Timber is a product virtually comprised of polysaccharides (cellulose as well as hemicelluloses) as well as lignins that will be weakened under ultraviolet photons’ activity. This photodegradation of the lignins, which is likewise emphasized in the existence of water, is accountable for the evolution of the shade of the timber. Greying is observed on the lumber used outdoors without any physical protection and also UV defense. This sensation creates an adjustment in the initial color of the raw timber in time, which often tends to end up being grey.
What Are the Consequences of Greying?
Greying or graying, which is an extremely superficial phenomenon, only influences the wooden structure’s appearances. It does not suggest a structural change as well as does not influence the solidity of the product. The look of this sensation is limited to the surface area of the wood. The loss of architectural resilience (which can go as far as the wreck of the material) is, for its part, because of strikes of biological beginning that affect the timber in its mass.
Is it possible to prevent the greying of the wood without maintaining it?
NO – Without ending up items and without upkeep, it would certainly be imaginary to assert to be able to prevent the timber from greying.
Will the application of a finish avoid the wood from transforming grey?
YES – If this application is made regularly, it is possible to avoid this phenomenon. The hydrophobic nature of the oil highly restricts the wood’s affinity for water as well as as a result delays its activity. Furniture Plan Number Sheet Sets Architecture
Fixed and also Thermo-Oiled Wood
Several recent procedures have actually made it possible to improve the sturdiness and dimensional stability of other varieties considerably: these are high-temperature heat treatments (210 to 250 ° C )in several phases, performed in unique heating systems, either under an inert ambience with nitrogen (fixed wood) or with water vapor injections (Finnish heat-treated lumber). The timber takes on a lovely brown color as well as becomes hydrophobic and also extremely immune to fungal or insect assaults. The high temperature compromises these timbers a little, which can not be used for structural functions (mainly in house siding, parquet, as well as balcony boards).
The supposed homeothermic procedure does not have this drawback: the wood is just warmed up to 130 ° C, with an immersion in a mix based on linseed oil and grease derivatives, which enables a deep impregnation. This additionally ensures a longer resistance to greying and also does not need regular maintenance. The procedure developers have actually begun to market it in France: three producers in the timber market have already bought it, and others are in the pipeline. The recent Wood-Protect process patented by Lapeyre and INRA-INPT in Toulouse is of the very same kind, with impregnation by autoclave and afterwards by soaking at 140 ° C in a mixture of grease by-products and also acetic acid.

High-temperature therapies make the wood entirely waterproof as well as fungi resistant.
The wood is given a temperature level in between 210 ° C and also 250 ° C in unique stoves. It then transforms color to come to be darker. The major negative aspect is that it sheds its stamina. It can after that just 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, as well as drying. Since the home heating temperature is lower than the previous method, the wood is much less breakable.
Research studies have revealed that homeothermic heating is useful when done after boron treatment. Boron has anti-inflammatory buildings. The problem is that it is not resistant to cleaning. Therefore, the homeothermic makes it feasible to fix the molecule and make the wood more resistant to flames, water, as well as shocks. For more information concerning this approach, here is a doctoral thesis that was done on the subject.
Oils, Spots, as well as Paints
The longevity of particular species such as oak as well as chestnut is mostly due to their high tannin content. However, these are gradually rinsed by rainwater, which is a little acidic. Like other species, oak and chestnut, therefore, need surface area defense. Linseed oil with a little turpentine added – to be made use of in heat (it passes through better) – is classic as well as cost-effective protection, water-repellent, and hold-ups greying.
Organic timber discolorations, which are colored yet reveal the timber grain, supply better defense versus UV rays thanks to the pigments they have. They need to be restored every 3 to 5 years for the south facades as well as every 8 to 10 years for the north facades. Unlike paints, they do not need sanding prior to renewal (a brush stroke suffices to eliminate the pigment dirt). When it comes to organic lacquer paints, they provide more sturdy security because they consist of fillers (particularly chalk) that develop an entire screen versus UV rays. It’s a little bit like sun creams; the safety and security relies on the display’s quality as well as the exposure. Furniture Plan Number Sheet Sets Architecture
To boost the durability of outside timber naturally, opt for a tarnish, for example, a combination of linseed oil and also turpentine. Some readily offered wood stains are tinted as well as give mild UV defense. The advantage of this technique is that no sanding is called for.
For even better defense, use natural lacquer paint. It will certainly offer ideal protection versus ultraviolet rays– prefer microporous paints including chalk fillers to allow the timber take a breath.
Shielding outside wood naturally can be finished with a safety stain or heat treatment. The option of method depends on the attributes that you desire to change. If specific wood types can be utilized without defense, they should be discolored after a particular duration because the protective tannins will have gone away. If you do refrain from doing this, you will certainly need to have a specialist dampness therapy.
Securing Timber from Water
Shielding wood from water is a necessary feature of an outside surface before any attractive aspect. It is suggested to conserve the material with paint, varnish, discolor, saturator, or oil. It is necessary to achieve a real obstacle effect, which must be water-proof if the timber is not to weaken also promptly.
This makes it possible to preserve all-natural, solid, raw, or veneered timber practically gradually. It is secured to maintain for several years despite the numerous weather hostilities encountered. It is durably protected from moisture, rainfall, poor climate, light, sun, as well as ultraviolet rays, making it age too soon. Furniture Plan Number Sheet Sets Architecture
Continue To Be Normally Absorptive to Dampness
Stay dampness permeableStaying normally permeable to smoke is extremely crucial. Wood is comprised of plant fibers that have a superb fondness with water. It is, as a result, a fragile material that stays conveniently absorptive to water. It remains specifically sensitive to different liquids that permeate it.
Wood absorbs very rapidly the moisture that is present in the ambient ambience. It soaks up water before normally launching it because it is a hygroscopic material. It remains in continuous stability with its environment, whatever the moisture content.
These different moisture variants are at the origin of the typical dimensional changes of wood. They have the impact of creating deformations that can in some cases be substantial. It functions by swelling if the air is also damp. It diminishes when the ambience becomes drier.
Rainfall, showers, thunderstorms, as well as various other poor weather condition that touch with the wood can create the look of unpleasant discolorations, streaks, leaks, and also halos. Moisture, infiltration, condensation, as well as water vapor are additionally responsible for the early aging of wood for many years. Furniture Plan Number Sheet Sets Architecture
Do Not Prevent Exchanges with The Outdoors.
Do not avoid exchanges with the outside not avoid interactions with the exterior; it has to be appreciated. When you intend to safeguard the timber, a water-repellent item has to be applied to avoid water from permeating it. It must be guaranteed that it is not impregnated by moisture if it is to last over the long-term.
A wood treatment item can only be perfectly ideal if it respects the different dampness exchanges. The timber needs to be able to remain to regulate itself with its atmosphere. It is vital to make certain that the film continues to be adequately micro-porous to assure a good exchange performance.
On the other hand, impermeability and water tightness must not be confused, which are very various concepts. Waterproofing needs to be restricted in the case of timber protection. Making a wood entirely watertight may cause the material to rot in the long-term.
Gas exchange, which manages the dampness material in the timber’s pores, have to never ever be protected against. A timber paint should enable the substrate to take a breath without ever quiting the internal emptying to the outside. It needs to simply stop water from penetrating the heart of the wood, not to modify or deteriorate it.
Choosing a Right Timber Treatment Item
Picking a wood treatment picking the ideal wood treatment product is necessary to safeguard wood successfully with time. There are different types of items that are capable of successfully protecting this material. One can utilize an item that passes through deeply, such as oil, impregnation, or saturator.
A penetrating therapy supplies a lot more effective protection than an item that deposits a film on the surface, such as paint, varnish, or sealant, as an example. While a film-forming product may seem valuable at first, this is not constantly the instance in the lengthy term.
They can end up splitting, flaking, breaking, or peeling off over the years. Infiltration, water, or moisture permeates the product, which ends up being improperly shielded. It is then important to sand or strip the surface area of the wood to bare it again to be preserved.
Silicones are extensively made use of in timber waterproofing items. These harmful substances need to be stayed clear of similarly as oil solvents, which are still existing in several items. They are not safe to the user, the environment, or nature. It is much better to select a bio-sourced product of plant origin that is consistent with this all-natural material.

Keep On A Regular Basis for Adequate Defense.
Preserve permanently protection preserve frequently for an ample protection, remains a procedure that ought to not be neglected to do. No matter the type of waterproofing picked to preserve the timber, it is essential to preserve it on a regular basis to ensure that the security continues to be adequately efficient over time.
Tiresome preparation, sanding, gritting, or removing of the surface area can be avoided making use of an oil, saturator, or impregnation. They have the particularity of protecting the product throughout its mass without creating a film externally that can flake off later.
A waterproofing representative’s function is to shield the wood from discolorations, marks, rings, and day-to-day damage. It is normally related to an anti UV agent that will certainly stop the timber from coming to be as well grey over time. It therefore limits the phenomenon of swelling or shrinkage.
A non-film-forming water repellent has several benefits for preserving a wood surface area. It is extremely efficient versus negative climate thanks to a barrier effect. It continues to be extremely efficient in nourishing the timber in all its deepness to the product’s very heart. It also shields the assistance from light, sunlight, and also ultraviolet rays.
