Outdoor timber has two main opponents: UV (ultraviolet rays from sunshine) as well as moisture. The first causes a sort of superficial shed – like on our skin, resulting in tiny fractures and also greying. Nothing remarkable, the damages is primarily visual, and also the timber is not affected detailed. Diy Furniture Backing
Wetness postures far more serious troubles: if rain does not run off or does not vaporize rapidly, if the wood remains in contact with the ground or if the wetness can climb by capillary activity, the moisture material of the wood will allow the installation of lignivorous fungis that are forerunners to rot and also favor attacks by wood-eating insects. Can chemical preservative therapies be stayed clear of?
Resilient Variety, without Sapwood
Some normally sturdy types from our areas can be made use of without treatment when the timber is laid vertically (risk class 3) and allows excellent water drain (cladding, home windows, shutters): in particular Douglas, larch, chestnut, oak, and cicada. Just the last three varieties are recommended when the timber is laid horizontally (terrace or terrace boards) or in contact with the ground (danger class 4). These timbers must additionally be selected and cut in such a method regarding remove the sapwood, the peripheral part of the trunk abundant in sugars, which brings in wood-eating pests.

What Are the Benefits of Safeguarding Your Timber?
Embellishes and also Safeguards
Past maintaining the aesthetic element over time, making use of a wood oil or a saturator in the defense of wood will restore its original shade and improve the grain of the timber while preserving its natural look.
Stabilizes the Timber
Oiling a timber enables enhancing its dimensional security durably, therefore reducing the sensations of contortion (tiling, swelling, as well as contraction), breaking, or surface area splitting.
All-natural as well as Ecological
Choosing an “Oleobois” safety oil indicates selecting a healthy and eco-friendly service; the structure omits fungicides, turpentine, as well as any oil by-products frequently made use of (paraffin, white spirit, …).
Easy and also Economical Maintenance
Maintenance is very easy since when oiled; wood does not need to be stripped or fined sand prior to restoration: a cleansing with black soap followed by a basic re-oiled surface area suffices. Diy Furniture Backing
Greying of The Wood
What Is Wood Graying?
Timber is a material almost made up of polysaccharides (cellulose and hemicelluloses) and lignins that will be deteriorated under ultraviolet photons’ activity. This photodegradation of the lignins, which is also accentuated in the existence of water, is in charge of the development of the shade of the timber. Greying is observed on the lumber used outdoors with no physical defense and also UV protection. This sensation triggers a modification in the original color of the raw wood over time, which has a tendency to become grey.
What Are the Consequences of Greying?
Greying or graying, which is a very superficial phenomenon, just impacts the wooden framework’s visual appeals. It does not suggest an architectural alteration and also does not impact the strength of the product. The appearance of this phenomenon is limited to the surface of the wood. The loss of structural toughness (which can reach the spoil of the material) is, for its part, because of strikes of biological origin that affect the timber in its mass.
Is it possible to prevent the greying of the timber without keeping it?
NO – Without ending up items and without maintenance, it would certainly be imaginary to assert to be able to stop the wood from greying.
Will the application of a coating prevent the timber from turning gray?
YES – If this application is made on a regular basis, it is feasible to prevent this sensation. The hydrophobic nature of the oil strongly limits the wood’s affinity for water as well as consequently delays its action. Diy Furniture Backing
Remedied and also Thermo-Oiled Timber
A number of recent procedures have actually made it feasible to improve the sturdiness and dimensional stability of various other varieties dramatically: these are high-temperature warmth treatments (210 to 250 ° C )in numerous stages, executed in special furnaces, either under an inert atmosphere with nitrogen (corrected wood) or with water vapor shots (Finnish heat-treated lumber). The timber handles a stunning brownish shade as well as ends up being hydrophobic and also really resistant to fungal or insect assaults. The high temperature deteriorates these timbers a little, which can not be made use of for structural purposes (generally in siding, parquet, and terrace boards).
The supposed homeothermic process does not have this negative aspect: the timber is just warmed up to 130 ° C, with an immersion in a blend based upon linseed oil as well as vegetable oil derivatives, which permits a deep impregnation. This likewise makes certain a much longer resistance to greying as well as does not need normal upkeep. The procedure designers have begun to market it in France: 3 producers in the timber market have already bought it, and others remain in the pipe. The current Wood-Protect process patented by Lapeyre as well as INRA-INPT in Toulouse is of the very same type, with impregnation by autoclave and afterwards by saturating at 140 ° C in a combination of grease by-products and acetic acid.

High-temperature treatments make the wood wholly waterproof as well as fungus resistant.
The timber is given a temperature level in between 210 ° C and 250 ° C in unique stoves. It after that transforms color to end up being darker. The main downside is that it loses its stamina. It can after that only be made use of for cladding or flooring.
Oleothermy is a therapy that contains 3 phases: heating to 130 ° C in a rapeseed oil bathroom, cooling down in a linseed oil bathroom, as well as drying. Considering that the heating temperature is lower than the previous method, the timber is less weak.
Researches have actually shown that homeothermic home heating is valuable when done after boron treatment. Boron has anti-inflammatory residential or commercial properties. The issue is that it is not immune to washing. Thus, the homeothermic makes it possible to repair the particle and make the timber much more resistant to fires, water, as well as shocks. To learn more regarding this approach, below is a doctoral thesis that was done on the topic.
Oils, Discolorations, and Paints
The toughness of certain varieties such as oak and chestnut is mostly as a result of their high tannin web content. These are slowly washed out by rain, which is somewhat acidic. Like other species, oak and also chestnut, consequently, need surface defense. Linseed oil with a little turpentine added – to be made use of in heat (it penetrates much better) – is traditional as well as cost-effective security, water-repellent, and delays greying.
Organic wood discolorations, which are tinted however reveal the wood grain, offer far better security versus UV rays thanks to the pigments they include. Nonetheless, they need to be renewed every 3 to 5 years for the south facades and every 8 to one decade for the north exteriors. Unlike paints, they do not call for sanding before renewal (a brush stroke suffices to remove the pigment dust). When it comes to natural lacquer paints, they supply more durable protection since they consist of fillers (particularly chalk) that form an entire screen versus UV rays. It’s a little bit like sun creams; the protection depends on the display’s quality and the exposure. Diy Furniture Backing
To enhance the longevity of exterior wood naturally, go with a tarnish, for example, a mixture of linseed oil and also turpentine. Some readily readily available wood spots are colored and also give small UV protection. The advantage of this technique is that no sanding is called for.
For also better protection, use organic lacquer paint. It will give optimum defense against ultraviolet rays– favor microporous paints containing chalk fillers to allow the wood take a breath.
Protecting outside timber normally can be performed with a safety discolor or heat treatment. The option of approach depends upon the attributes that you want to customize. If specific wood types can be used without defense, they should be tarnished after a particular period due to the fact that the protective tannins will have disappeared. If you do not do this, you will certainly have to have a professional moisture therapy.
Protecting Timber from Water
Shielding timber from water is an important function of an outside finish prior to any attractive element. It is recommended to conserve the material with paint, varnish, tarnish, saturator, or oil. It is necessary to accomplish an actual obstacle result, which need to be waterproof if the wood is not to deteriorate too quickly.
This makes it possible to preserve natural, strong, raw, or veneered timber essentially with time. It is shielded to keep for years despite the numerous climatic hostilities encountered. It is durably maintained from moisture, rain, negative weather, light, sunlight, and also ultraviolet rays, making it age prematurely. Diy Furniture Backing
Stay Normally Absorptive to Moisture
Remain dampness permeableStaying naturally permeable to smoke is really vital. Timber is made up of plant fibers that have an excellent affinity with water. It is, as a result, a vulnerable product that remains easily absorptive to water. It remains particularly sensitive to different liquids that penetrate it.
Wood absorbs extremely promptly the moisture that exists in the ambient ambience. It absorbs water before normally releasing it due to the fact that it is a hygroscopic material. It continues to be in continuous balance with its environment, whatever the wetness web content.
These various moisture variations go to the origin of the normal dimensional improvements of wood. They have the impact of triggering contortions that can occasionally be significant. It functions by swelling if the air is too humid. It shrinks when the atmosphere ends up being drier.
Rain, showers, electrical storms, and also other bad weather that touch with the wood can create the look of undesirable discolorations, streaks, drips, and halos. Dampness, seepage, condensation, and water vapor are also responsible for the premature aging of wood throughout the years. Diy Furniture Backing
Do Not Protect against Exchanges with The Outside World.
Do not stop exchanges with the outdoors not protect against communications with the outside; it has to be respected. When you intend to protect the timber, a water-repellent product must be put on stay clear of water from penetrating it. It must be made sure that it is not fertilized by moisture if it is to last over the long term.
A timber treatment product can just be perfectly ideal if it values the various wetness exchanges. The timber must be able to continue to control itself with its environment. It is necessary to make sure that the film continues to be adequately micro-porous to ensure an excellent exchange efficiency.
On the other hand, impermeability as well as water tightness must not be puzzled, which are really different notions. Waterproofing must be banned in the case of wood security. Making a timber entirely watertight might trigger the product to rot in the long term.
Gas exchange, which manages the dampness web content in the timber’s pores, should never ever be stopped. A wood paint have to allow the substrate to breathe without ever quiting the inner evacuation to the exterior. It must just stop water from penetrating the heart of the timber, not to alter or degrade it.
Picking a Right Wood Therapy Product
Selecting a timber therapy picking the best timber treatment product is essential to protect timber efficiently over time. There are different sorts of products that are capable of efficiently maintaining this product. One can utilize an item that permeates deeply, such as oil, impregnation, or saturator.
A passing through therapy offers more effective defense than an item that deposits a movie on the surface, such as paint, varnish, or sealant, as an example. Indeed, while a film-forming item may appear helpful originally, this is not always the situation in the long term.
Certainly, they can end up breaking, flaking, fracturing, or removing throughout the years. Infiltration, water, or humidity permeates the material, which becomes inadequately insulated. 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 made use of in timber waterproofing items. These unsafe compounds should be prevented similarly as petroleum solvents, which are still present in numerous items. They are not safe to the user, the atmosphere, or nature. It is better to pick a bio-sourced product of plant beginning that is consistent with this all-natural material. Diy Furniture Backing
Preserve Routinely for Adequate Security.
Preserve forever protection preserve on a regular basis for an ample defense, continues to be an operation that should not be neglected to execute. Regardless of the sort of waterproofing picked to maintain the timber, it is necessary to preserve it routinely to make sure that the protection remains completely reliable gradually.
Tedious prep work, fining sand, gritting, or stripping of the surface can be avoided using an oil, saturator, or impregnation. They have the particularity of shielding the material throughout its mass without creating a film on the surface that can exfoliate afterward.
A waterproofing representative’s function is to protect the wood from spots, marks, rings, and also daily wear and tear. It is normally related to an anti UV agent that will certainly protect against the timber from ending up being too grey over time. It thus restricts the sensation of swelling or shrinking.
A non-film-forming water repellent has many benefits for maintaining a wooden surface. It is very reliable versus negative weather condition thanks to an obstacle impact. Also, it stays extremely effective in nourishing the wood in all its deepness to the material’s very heart. It additionally secures the support from light, sunlight, and ultraviolet rays.
