Outside timber has two primary adversaries: UV (ultraviolet rays from sunlight) and also humidity. The first causes a sort of shallow shed – like on our skin, resulting in small fractures as well as greying. Nothing significant, the damage is mainly visual, as well as the wood is not affected detailed. Material Tag On A Furniture Plan
Dampness poses much more serious issues: if rain does not escape or does not evaporate quickly, if the timber continues to be in contact with the ground or if the moisture can increase by capillary activity, the moisture material of the wood will certainly permit the installment of lignivorous fungis that are precursors to rot and favor assaults by wood-eating pests. Can chemical preservative therapies be avoided?
Sturdy Types, without Sapwood
Some naturally resilient species from our regions can be made use of without therapy when the wood is laid up and down (threat class 3) as well as permits excellent water drainage (cladding, windows, shutters): in particular Douglas, larch, chestnut, oak, as well as cicada. Just the last 3 types are recommended when the wood is laid horizontally (terrace or terrace boards) or in contact with the ground (risk course 4). These timbers have to likewise be chosen and also cut in such a means as to eliminate the sapwood, the peripheral part of the trunk rich in sugars, which draws in wood-eating pests.

What Are the Benefits of Shielding Your Timber?
Embellishes and also Secures
Beyond preserving the aesthetic aspect in time, making use of a timber oil or a saturator in the defense of timber will restore its original shade and also boost the grain of the timber while maintaining its all-natural appearance.
Supports the Wood
Fueling oil a timber allows enhancing its dimensional security durably, hence reducing the sensations of deformation (tiling, swelling, and contraction), splitting, or surface area splitting.
All-natural and Ecological
Choosing an “Oleobois” protective oil suggests picking a healthy and eco-friendly solution; the structure leaves out fungicides, turpentine, as well as any type of petroleum derivatives often made use of (paraffin, white spirit, …).
Easy and Economical Upkeep
Maintenance is simple since as soon as oiled; wood does not require to be removed or fined sand before restoration: a cleaning with black soap followed by a basic re-oiled surface is enough. Material Tag On A Furniture Plan
Greying of The Wood
What Is Timber Graying?
Timber is a material almost made up of polysaccharides (cellulose and hemicelluloses) and lignins that will be broken down under ultraviolet photons’ action. This photodegradation of the lignins, which is likewise accentuated in the presence of water, is accountable for the advancement of the color of the wood. Greying is observed on the lumber used outdoors with no physical security as well as UV protection. This phenomenon creates an adjustment in the original shade of the raw timber gradually, which has a tendency to come to be gray.
What Are the Repercussions of Greying?
Greying or graying, which is a very surface sensation, just impacts the wood framework’s looks. It does not show an architectural modification and also does not influence the strength of the product. The appearance of this sensation is restricted to the surface area of the wood. The loss of architectural durability (which can reach the ruin of the product) is, for its component, because of assaults of biological origin that affect the timber in its mass.
Is it feasible to avoid the greying of the wood without maintaining it?
NO – Without completing products and without upkeep, it would be imaginary to claim to be able to prevent the timber from greying.
Will the application of a coating stop the wood from turning grey?
YES – If this application is made on a regular basis, it is feasible to avoid this phenomenon. The hydrophobic nature of the oil strongly restricts the wood’s affinity for water as well as as a result postpones its action. Material Tag On A Furniture Plan
Rectified and also Thermo-Oiled Timber
A number of recent processes have made it possible to enhance the durability and dimensional stability of various other types dramatically: these are high-temperature warmth treatments (210 to 250 ° C )in several phases, accomplished in special heating systems, either under an inert atmosphere with nitrogen (remedied timber) or with water vapor injections (Finnish heat-treated lumber). The wood handles a gorgeous brownish color as well as becomes hydrophobic and very immune to fungal or insect assaults. However, the high temperature damages these timbers a little, which can not be utilized for architectural purposes (generally in exterior siding, parquet, and terrace boards).
The so-called homeothermic procedure does not have this drawback: the timber is only warmed up to 130 ° C, with an immersion in a mixture based on linseed oil and also grease by-products, which allows a deep impregnation. This also makes sure a longer resistance to greying and also does not need routine upkeep. The process makers have actually started to market it in France: three makers in the wood industry have currently bought it, and also others remain in the pipeline. The recent Wood-Protect procedure patented by Lapeyre as well as INRA-INPT in Toulouse is of the very same type, with impregnation by autoclave and after that by soaking at 140 ° C in a mix of grease derivatives as well as acetic acid.

High-temperature therapies make the wood wholly water resistant as well as fungi immune.
The wood is offered a temperature level in between 210 ° C and also 250 ° C in special stoves. It then transforms color to become darker. The major negative aspect is that it loses its strength. It can after that just be made use of for cladding or floor covering.
Oleothermy is a treatment that contains 3 stages: heating to 130 ° C in a rapeseed oil bath, cooling down in a linseed oil bathroom, as well as drying out. Considering that the heating temperature is less than the previous method, the timber is less brittle.
Researches have actually shown that homeothermic heating is valuable when done after boron treatment. Boron has anti-inflammatory buildings. The problem is that it is not immune to cleaning. Hence, the homeothermic makes it feasible to deal with the molecule and also make the wood much more resistant to flames, water, as well as shocks. To read more regarding this technique, right here is a doctoral thesis that was done on the topic.
Oils, Stains, and Paints
The toughness of specific varieties such as oak as well as chestnut is mostly because of their high tannin web content. These are gradually washed out by rain, which is somewhat acidic. Like various other types, oak and chestnut, therefore, require surface protection. Linseed oil with a little turpentine included – to be utilized in hot weather (it penetrates much better) – is traditional and also inexpensive defense, water-repellent, and also hold-ups greying.
Organic timber stains, which are colored however reveal the timber grain, provide much better security against UV rays thanks to the pigments they consist of. They must be restored 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 prior to revival (a brush stroke suffices to eliminate the pigment dirt). When it comes to organic lacquer paints, they offer more long lasting protection given that they contain fillers (particularly chalk) that form a whole screen against UV rays. It’s a little bit like sun creams; the safety depends upon the display’s quality and also the exposure. Material Tag On A Furniture Plan
Surface area Protection
To enhance the toughness of outside wood naturally, go with a discolor, as an example, a mixture of linseed oil as well as turpentine. Some commercially readily available timber stains are colored and give slight UV security. The benefit of this technique is that no sanding is needed.
For even better defense, use natural lacquer paint. It will certainly offer optimum security against ultraviolet rays– prefer microporous paints consisting of chalk fillers to allow the wood breathe.
Safeguarding outside timber normally can be done with a protective tarnish or heat therapy. The option of method depends on the characteristics that you desire to modify. If specific wood species can be used without defense, they must be stained after a specific duration because the safety tannins will certainly have vanished. If you do refrain from doing this, you will certainly need to have a professional moisture therapy.
Shielding Wood from Water
Shielding wood from water is a crucial function of an outside surface before any attractive facet. It is advised to save the material with paint, varnish, discolor, saturator, or oil. It is important to accomplish a real barrier effect, which need to be water-proof if the timber is not to wear away too quickly.
This makes it possible to protect natural, strong, raw, or veneered timber practically over time. It is protected to maintain for many years despite the various weather hostilities came across. It is durably maintained from moisture, rain, bad weather condition, light, sun, as well as ultraviolet rays, making it age prematurely. Material Tag On A Furniture Plan
Remain Naturally Absorptive to Wetness
Remain wetness permeableStaying normally absorptive to smoke is very vital. Timber is comprised of plant fibers that have an exceptional affinity with water. It is, consequently, a delicate material that remains easily absorptive to water. It continues to be especially conscious numerous liquids that permeate it.
Timber takes in extremely promptly the humidity that exists in the ambient atmosphere. It absorbs water before naturally releasing it due to the fact that it is a hygroscopic material. It stays in constant balance with its atmosphere, whatever the moisture web content.
These various moisture variants go to the beginning of the common dimensional transformations of timber. They have the effect of triggering contortions that can occasionally be substantial. It works by swelling if the air is also moist. It shrinks when the atmosphere becomes drier.
Rainfall, showers, thunderstorms, and other bad weather condition that are in contact with the wood can create the look of unpleasant discolorations, streaks, drips, and also halos. Moisture, infiltration, condensation, and water vapor are additionally in charge of the premature aging of timber for many years. Material Tag On A Furniture Plan
Do Not Stop Exchanges with The Outside World.
Do not protect against exchanges with the outdoors not avoid interactions with the exterior; it should be appreciated. When you intend to protect the timber, a water-repellent item needs to be related to prevent water from permeating it. It has to be guaranteed that it is not impregnated by dampness if it is to last over the long-term.
A timber treatment product can just be completely ideal if it appreciates the various moisture exchanges. The timber needs to be able to remain to control itself with its setting. It is important to guarantee that the film continues to be completely micro-porous to guarantee an excellent exchange efficiency.
On the other hand, impermeability and water rigidity need to not be puzzled, which are extremely different concepts. Waterproofing must be prohibited when it comes to timber security. Making a wood totally watertight might cause the product to rot in the long term.
Gas exchange, which controls the dampness web content in the wood’s pores, should never ever be stopped. A timber paint should enable the substrate to take a breath without ever before quiting the interior evacuation to the exterior. It should simply protect against water from permeating the heart of the timber, not to change or degrade it.
Selecting a Right Timber Treatment Product
Selecting a wood treatment choosing the best wood therapy product is necessary to shield timber efficiently with time. There are various kinds of items that can successfully maintaining this material. One can utilize an item that passes through deeply, such as oil, impregnation, or saturator.
A penetrating treatment gives a lot more efficient protection than a product that transfers a movie on the surface area, such as paint, varnish, or sealant. While a film-forming product might appear beneficial at first, this is not constantly the case in the long term.
They can end up splitting, flaking, cracking, or peeling off over the years. Seepage, water, or moisture permeates the material, which comes to be poorly shielded. It is after that essential to sand or strip the surface of the timber to bare it once again to be maintained.
Silicones are commonly made use of in wood waterproofing items. These dangerous compounds should be avoided similarly as oil solvents, which are still present in lots of products. They are not safe to the user, the atmosphere, or nature. It is better to choose a bio-sourced product of plant origin that follows this all-natural material. Material Tag On A Furniture Plan
Maintain Frequently for Adequate Protection.
Maintain for good defense keep routinely for an appropriate protection, continues to be a procedure that needs to not be failed to remember to execute. Despite the sort of waterproofing chosen to preserve the timber, it is required to keep it regularly to make sure that the defense remains sufficiently reliable in time.
Laborious prep work, sanding, gritting, or stripping of the surface can be prevented utilizing an oil, saturator, or impregnation. They have the particularity of securing the material throughout its mass without creating a movie externally that can flake off later.
A waterproofing agent’s feature is to safeguard the timber from spots, marks, rings, as well as daily damage. It is generally connected with an anti UV representative that will certainly avoid the timber from coming to be as well grey in the long run. It therefore restricts the phenomenon of swelling or contraction.
A non-film-forming water repellent has lots of benefits for preserving a wooden surface. It is very reliable versus negative weather condition thanks to a barrier effect. Likewise, it continues to be very effective in nurturing the timber in all its deepness to the material’s actual heart. It also protects the assistance from light, sun, and ultraviolet rays.
