Exterior timber has 2 main enemies: UV (ultraviolet rays from sunlight) and also moisture. The first causes a kind of surface melt – like on our skin, causing tiny fractures and also greying. Absolutely nothing dramatic, the damage is primarily aesthetic, as well as the timber is not impacted in depth. Mdf Furniture Diy
Dampness postures much more severe issues: if rainwater does not run off or does not vaporize quickly, if the timber stays touching the ground or if the dampness can climb by capillary activity, the dampness content of the timber will allow the installment of lignivorous fungis that are forerunners to rot and also favor assaults by wood-eating bugs. Can chemical preservative therapies be avoided?
Durable Species, without Sapwood
Some normally long lasting types from our regions can be used without therapy when the timber is laid up and down (risk class 3) as well as permits good water drainage (cladding, home windows, shutters): specifically Douglas, larch, chestnut, oak, as well as locust. Just the last three types are suggested when the wood is laid horizontally (veranda or balcony boards) or touching the ground (threat class 4). These timbers must additionally be chosen as well as cut in such a way regarding remove the sapwood, the outer part of the trunk abundant in sugars, which draws in wood-eating bugs. Mdf Furniture Diy
What Are the Advantages of Safeguarding Your Wood?
Embellishes as well as Secures
Past maintaining the visual element over time, utilizing a timber oil or a saturator in the security of wood will restore its initial shade and boost the grain of the timber while maintaining its natural look.
Maintains the Wood
Oiling a wood allows boosting its dimensional security durably, therefore lowering the sensations of deformation (tiling, swelling, as well as shrinkage), breaking, or surface splitting.
All-natural and Ecological
Choosing an “Oleobois” protective oil means picking a healthy and also environmentally friendly remedy; the structure excludes fungicides, turpentine, and any kind of oil by-products frequently made use of (paraffin, white spirit, …).
Easy and also Economical Maintenance
Maintenance is simple due to the fact that when oiled; timber does not require to be removed or sanded before renovation: a cleansing with black soap followed by a straightforward re-oiled surface area suffices. Mdf Furniture Diy
Greying of The Timber
What Is Wood Graying?
Timber is a material almost comprised of polysaccharides (cellulose and also hemicelluloses) and lignins that will be broken down under ultraviolet photons’ activity. This photodegradation of the lignins, which is additionally highlighted in the existence of water, is responsible for the advancement of the shade of the timber. Greying is observed on the lumber utilized outdoors with no physical defense as well as UV protection. This sensation creates a change in the initial color of the raw wood with time, which tends to end up being grey.
What Are the Consequences of Greying?
Greying or graying, which is an extremely shallow sensation, just affects the wood framework’s looks. It does not indicate an architectural change and does not influence the solidity of the material. The appearance of this sensation is restricted to the surface of the wood. The loss of structural resilience (which can reach the ruin of the product) is, for its component, because of assaults of biological beginning that influence the timber in its mass.
Is it feasible to prevent the greying of the wood without keeping it?
NO – Without ending up products as well as without maintenance, it would certainly be imaginary to claim to be able to prevent the wood from greying.
Will the application of a finish protect against the timber from turning grey?
YES – If this application is made routinely, it is possible to avoid this phenomenon. The hydrophobic nature of the oil highly restricts the wood’s affinity for water and also for that reason postpones its activity. Mdf Furniture Diy
Rectified and Thermo-Oiled Timber
Numerous recent procedures have made it feasible to improve the toughness and dimensional stability of various other varieties significantly: these are high-temperature heat treatments (210 to 250 ° C )in numerous stages, carried out in special furnaces, either under an inert ambience with nitrogen (remedied timber) or with water vapor injections (Finnish heat-treated lumber). The wood takes on an attractive brownish color and comes to be hydrophobic and extremely immune to fungal or insect assaults. The high temperature compromises these timbers a little, which can not be used for architectural purposes (generally in exterior siding, parquet, and also balcony 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 mixture based upon linseed oil and grease by-products, which allows a deep impregnation. This likewise ensures a much longer resistance to greying as well as does not require regular maintenance. The procedure designers have started to market it in France: three manufacturers in the timber market have actually currently bought it, as well as others are in the pipeline. The current Wood-Protect procedure patented by Lapeyre and also INRA-INPT in Toulouse is of the exact same type, with impregnation by autoclave and then by soaking at 140 ° C in a mixture of vegetable oil by-products and also acetic acid.

High-temperature treatments make the timber completely waterproof and fungus immune.
The wood is offered a temperature level between 210 ° C and 250 ° C in unique stoves. It then transforms shade to end up being darker. The main downside is that it loses its strength. It can then just be made use of for cladding or flooring.
Oleothermy is a treatment that consists of 3 stages: home heating to 130 ° C in a rapeseed oil bath, cooling in a linseed oil bathroom, and drying. Since the home heating temperature is less than the previous method, the timber is less fragile.
Researches have actually shown that homeothermic heating is advantageous when done after boron treatment. Boron has anti-inflammatory residential or commercial properties. The problem is that it is not resistant to washing. Thus, the homeothermic makes it possible to fix the molecule as well as make the wood more immune to flames, water, and also shocks. To get more information concerning this method, here is a doctoral thesis that was done on the topic.
Oils, Discolorations, and also Paints
The longevity of specific varieties such as oak as well as chestnut is mainly due to their high tannin content. These are slowly cleaned out by rainwater, which is somewhat acidic. Like various other species, oak and also chestnut, consequently, need surface area defense. Linseed oil with a little turpentine included – to be utilized in hot weather (it penetrates much better) – is traditional and affordable security, water-repellent, as well as hold-ups greying.
Organic wood stains, which are tinted however reveal the wood grain, supply much better protection against UV rays thanks to the pigments they consist of. They need to be renewed every 3 to 5 years for the south facades and also every 8 to 10 years for the north facades. Unlike paints, they do not call for sanding before renewal (a brush stroke suffices to eliminate the pigment dust). When it comes to organic lacquer paints, they give even more sturdy defense because they have fillers (especially chalk) that develop an entire display versus UV rays. It’s a little bit like sun creams; the security relies on the screen’s quality and the direct exposure. Mdf Furniture Diy
To boost the sturdiness of exterior wood naturally, opt for a tarnish, for instance, a combination of linseed oil and turpentine. Some commercially readily available wood spots are tinted and also give small UV protection. The advantage of this approach is that no sanding is required.
For also much better protection, apply organic lacquer paint. It will give optimum defense against ultraviolet rays– favor microporous paints containing chalk fillers to let the timber take a breath.
Protecting exterior timber normally can be performed with a protective stain or warm treatment. The option of technique depends upon the characteristics that you want to modify. If particular timber varieties can be used without security, they must be stained after a specific duration due to the fact that the safety tannins will have vanished. If you do refrain this, you will certainly need to have a professional moisture treatment.
Safeguarding Wood from Water
Safeguarding wood from water is an essential function of an exterior coating before any decorative element. It is advised to save the product with paint, varnish, stain, saturator, or oil. It is crucial to accomplish an actual obstacle effect, which need to be water resistant if the wood is not to weaken too promptly.
This makes it feasible to protect all-natural, solid, raw, or veneered wood essentially with time. It is shielded to keep for many years in the face of the various climatic aggressions encountered. It is durably protected from moisture, rain, negative weather condition, light, sun, and ultraviolet rays, making it age prematurely. Mdf Furniture Diy
Remain Naturally Permeable to Wetness
Continue to be dampness permeableStaying normally permeable to smoke is very important. Timber is made up of plant fibers that have an outstanding affinity with water. It is, consequently, a vulnerable product that continues to be quickly permeable to water. It continues to be specifically sensitive to various fluids that penetrate it.
Timber absorbs really swiftly the humidity that is present in the ambient environment. It takes in water before normally releasing it since it is a hygroscopic product. It stays in consistent equilibrium with its atmosphere, whatever the wetness content.
These various moisture variants go to the beginning of the normal dimensional transformations of wood. They have the impact of causing contortions that can occasionally be substantial. It works by swelling if the air is too moist. It diminishes when the environment ends up being drier.
Rainfall, showers, electrical storms, and various other poor weather condition that touch with the timber can create the look of undesirable discolorations, streaks, trickles, and also halos. Moisture, seepage, condensation, and also water vapor are also in charge of the early aging of timber throughout the years. Mdf Furniture Diy
Do Not Avoid Exchanges with The Outside World.
Do not avoid exchanges with the outdoors not avoid communications with the exterior; it needs to be respected. When you wish to protect the wood, a water-repellent product needs to be put on stay clear of 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 wood treatment product can only be flawlessly suitable if it values the various moisture exchanges. The timber needs to be able to remain to control itself with its setting. It is essential to ensure that the film continues to be sufficiently micro-porous to ensure a great exchange efficiency.
On the other hand, impermeability and also water rigidity need to not be confused, which are really various concepts. Waterproofing needs to be prohibited when it comes to wood security. Making a wood totally watertight might create the product to rot in the long-term.
Gas exchange, which regulates the dampness web content in the timber’s pores, must never be protected against. A timber paint should permit the substratum to take a breath without ever quiting the interior discharge to the exterior. It should just prevent water from permeating the heart of the wood, not to change or deteriorate it.
Choosing a Right Timber Treatment Product
Choosing a wood therapy picking the best wood therapy product is important to safeguard wood efficiently gradually. There are different kinds of products that can effectively protecting this product. One can make use of a product that penetrates deeply, such as oil, impregnation, or saturator.
A penetrating therapy supplies more efficient protection than a product that deposits a movie externally, such as paint, varnish, or sealer, for instance. Undoubtedly, while a film-forming item may appear valuable initially, this is not always the situation in the long-term.
They can finish up cracking, flaking, fracturing, or peeling off over the years. Infiltration, water, or humidity permeates the material, which comes to be improperly shielded. It is after that necessary to sand or strip the surface area of the wood to bare it again to be protected.
Silicones are commonly used in wood waterproofing products. These unsafe substances must be avoided in the same way as petroleum solvents, which are still existing in several items. They are not harmless to the user, the atmosphere, or nature. It is much better to pick a bio-sourced product of plant origin that is consistent with this natural product. Mdf Furniture Diy
Preserve Regularly for Adequate Security.
Keep forever protection keep regularly for an appropriate protection, remains an operation that should not be forgotten to carry out. Despite the kind of waterproofing chosen to preserve the timber, it is required to maintain it regularly to ensure that the defense remains sufficiently efficient in time.
Tedious preparation, sanding, gritting, or stripping of the surface can be prevented making use of an oil, saturator, or impregnation. They have the particularity of shielding the material throughout its mass without developing a film on the surface that can flake off later.
A waterproofing agent’s function is to safeguard the timber from spots, marks, rings, as well as everyday wear and tear. It is typically related to an anti UV agent that will protect against the timber from ending up being too grey over time. It thus restricts the sensation of swelling or shrinkage.
A non-film-forming water repellent has many advantages for preserving a wood surface. It is really efficient versus negative weather condition thanks to a barrier result. Additionally, it stays very effective in nourishing the wood in all its deepness to the material’s very heart. It likewise secures the assistance from light, sun, and also ultraviolet rays.
