Outside wood has two major enemies: UV (ultraviolet rays from sunlight) and humidity. The first causes a type of superficial melt – like on our skin, resulting in tiny cracks and also greying. Absolutely nothing significant, the damages is generally visual, and the wood is not affected extensive. Open Floor Plan Living Room White Furniture Staircase
Dampness presents much more severe problems: if rainwater does not run off or does not evaporate rapidly, if the timber remains touching the ground or if the dampness can rise by capillary action, the dampness material of the timber will certainly permit the setup of lignivorous fungis that are precursors to rot and support attacks by wood-eating pests. Can chemical preservative treatments be stayed clear of?
Resilient Variety, without Sapwood
Some naturally long lasting species from our areas can be made use of without treatment when the timber is laid vertically (risk class 3) and allows excellent water drainage (cladding, home windows, shutters): in particular Douglas, larch, chestnut, oak, and locust. Only the last 3 types are advised when the timber is laid horizontally (balcony or balcony boards) or in contact with the ground (threat class 4). These timbers should additionally be selected and also cut in such a way regarding remove the sapwood, the outer part of the trunk rich in sugars, which brings in wood-eating bugs.

What Are the Advantages of Protecting Your Timber?
Embellishes as well as Safeguards
Past preserving the aesthetic element with time, utilizing a timber oil or a saturator in the defense of timber will certainly revitalize its original color and improve the grain of the wood while keeping its all-natural look.
Supports the Timber
Oiling a wood enables boosting its dimensional stability durably, thus lowering the phenomena of deformation (tiling, swelling, and shrinkage), splitting, or surface area splitting.
Natural and Ecological
Picking an “Oleobois” protective oil suggests picking a healthy and also environmentally friendly option; the make-up omits fungicides, turpentine, and any kind of petroleum derivatives regularly made use of (paraffin, white spirit, …).
Easy as well as Economical Upkeep
Maintenance is easy since as soon as fueled oil; wood does not require to be removed or sanded before improvement: a cleansing with black soap adhered to by an easy re-oiled surface area suffices. Open Floor Plan Living Room White Furniture Staircase
Greying of The Timber
What Is Timber Graying?
Timber is a material almost composed of polysaccharides (cellulose and also hemicelluloses) and also lignins that will be deteriorated under ultraviolet photons’ action. This photodegradation of the lignins, which is additionally accentuated in the presence of water, is responsible for the development of the color of the wood. Greying is observed on the lumber made use of outdoors with no physical defense and UV protection. This sensation creates an adjustment in the initial color of the raw wood with time, which tends to come to be grey.
What Are the Effects of Greying?
Greying or graying, which is an extremely surface sensation, only affects the wood structure’s visual appeals. It does not suggest an architectural modification as well as does not influence the strength of the material. The look of this phenomenon is limited to the surface of the wood. The loss of architectural longevity (which can reach the mess up of the material) is, for its component, due to strikes of organic beginning that influence the wood in its mass.
Is it feasible to prevent the greying of the wood without keeping it?
NO – Without completing products as well as without upkeep, it would be illusory to declare to be able to prevent the timber from greying.
Will the application of a coating prevent the timber from transforming gray?
YES – If this application is made frequently, it is possible to prevent this phenomenon. The hydrophobic nature of the oil strongly limits the wood’s fondness for water as well as for that reason postpones its activity. Open Floor Plan Living Room White Furniture Staircase
Rectified and also Thermo-Oiled Timber
A number of recent procedures have made it possible to enhance the resilience and also dimensional security of various other varieties dramatically: these are high-temperature warm treatments (210 to 250 ° C )in a number of stages, executed in unique heaters, either under an inert atmosphere with nitrogen (corrected wood) or with water vapor shots (Finnish heat-treated lumber). The timber takes on a gorgeous brownish color and becomes hydrophobic as well as very resistant to fungal or insect assaults. The high temperature weakens these woods a little, which can not be used for architectural purposes (mostly in siding, parquet, and terrace boards).
The so-called homeothermic procedure does not have this disadvantage: the wood is just heated up to 130 ° C, with an immersion in a combination based on linseed oil as well as grease derivatives, which enables a deep impregnation. This additionally ensures a longer resistance to greying as well as does not require regular maintenance. The procedure designers have started to market it in France: three producers in the timber market have currently bought it, and also others remain in the pipe. The current Wood-Protect process patented by Lapeyre and also INRA-INPT in Toulouse is of the same kind, with impregnation by autoclave and after that by soaking at 140 ° C in a mixture of grease by-products and also acetic acid.

High-temperature therapies make the timber completely water resistant and also fungi resistant.
The wood is offered a temperature level between 210 ° C and 250 ° C in unique ovens. It after that alters color to end up being darker. The primary drawback is that it loses its stamina. It can then just be used for cladding or flooring.
Oleothermy is a therapy that contains 3 phases: home heating to 130 ° C in a rapeseed oil bath, cooling down in a linseed oil bathroom, and also drying. Considering that the heating temperature level is less than the previous approach, the wood is much less brittle.
Studies have actually shown that homeothermic home heating is advantageous when done after boron therapy. Boron has anti-inflammatory residential properties. The problem is that it is not resistant to cleaning. Hence, the homeothermic makes it feasible to take care of the particle and also make the timber more resistant to flames, water, as well as shocks. To learn more regarding this approach, below is a doctoral thesis that was done on the topic.
Oils, Stains, as well as Paints
The longevity of specific species such as oak as well as chestnut is mostly due to their high tannin content. These are slowly washed out by rain, which is somewhat acidic. Like various other types, oak and also chestnut, as a result, require surface defense. Linseed oil with a little turpentine added – to be used in hot weather (it permeates much better) – is traditional as well as inexpensive security, water-repellent, and hold-ups greying.
Organic timber discolorations, which are colored however reveal the wood grain, provide much better defense versus UV rays thanks to the pigments they have. They should be renewed every 3 to 5 years for the south exteriors and also every 8 to 10 years for the north facades. Unlike paints, they do not call for sanding before revival (a brush stroke is enough to remove the pigment dust). As for organic lacquer paints, they supply even more sturdy defense given that they consist of fillers (particularly chalk) that create a whole display against UV rays. It’s a little bit like sun creams; the protection depends on the display’s quality as well as the exposure. Open Floor Plan Living Room White Furniture Staircase
To improve the resilience of outdoor timber naturally, select a discolor, for instance, a mixture of linseed oil as well as turpentine. Some commercially offered timber stains are colored and also offer mild UV defense. The benefit of this technique is that no sanding is needed.
For even far better protection, apply natural lacquer paint. It will give optimum security versus ultraviolet rays– favor microporous paints consisting of chalk fillers to let the timber take a breath.
Protecting exterior timber normally can be done with a protective tarnish or heat treatment. The selection of approach depends upon the features that you desire to change. If specific wood types can be used without protection, they have to be stained after a specific period because the protective tannins will certainly have gone away. If you do refrain from doing this, you will have to have an expert moisture treatment.
Safeguarding Wood from Water
Safeguarding wood from water is a vital feature of an outside finish prior to any ornamental facet. It is recommended to save the material with paint, varnish, stain, saturator, or oil. It is important to achieve a real barrier effect, which must be waterproof if the wood is not to weaken also quickly.
This makes it possible to protect natural, strong, raw, or veneered wood basically over time. It is protected to keep for years when faced with the different weather hostilities encountered. It is durably protected from moisture, rainfall, bad climate, light, sunlight, and also ultraviolet rays, making it age too soon. Open Floor Plan Living Room White Furniture Staircase
Continue To Be Naturally Permeable to Moisture
Continue to be wetness permeableStaying normally absorptive to smoke is extremely essential. Timber is made up of plant fibers that have a superb affinity with water. It is, as a result, a vulnerable material that stays conveniently permeable to water. It continues to be specifically sensitive to various liquids that permeate it.
Wood absorbs really promptly the humidity that exists in the ambient ambience. It absorbs water prior to normally launching it because it is a hygroscopic product. It remains in continuous equilibrium with its atmosphere, whatever the dampness content.
These various moisture variations go to the origin of the normal dimensional transformations of timber. They have the effect of causing deformations that can sometimes be considerable. It works by swelling if the air is too damp. It diminishes when the ambience becomes drier.
Rainfall, showers, thunderstorms, as well as other bad weather condition that are in contact with the timber can create the look of unsightly discolorations, streaks, trickles, as well as halos. Wetness, seepage, condensation, as well as water vapor are also responsible for the premature aging of timber for many years. Open Floor Plan Living Room White Furniture Staircase
Do Not Protect against Exchanges with The Outside World.
Do not protect against exchanges with the outside not protect against communications with the exterior; it has to be valued. When you wish to protect the timber, a water-repellent product needs to be applied to avoid water from permeating it. It should be made sure that it is not fertilized by dampness if it is to last over the long-term.
A wood treatment product can just be flawlessly appropriate if it respects the different moisture exchanges. The wood needs to have the ability to continue to control itself with its atmosphere. It is necessary to ensure that the movie stays adequately micro-porous to guarantee a great exchange performance.
On the other hand, impermeability and water tightness must not be confused, which are really different concepts. Waterproofing must be prohibited in the case of wood security. Making a wood entirely watertight might cause the product to rot in the long term.
Gas exchange, which controls the dampness web content in the timber’s pores, must never be stopped. A wood paint should enable the substrate to take a breath without ever before stopping the interior evacuation to the exterior. It must just avoid water from permeating the heart of the timber, not to alter or degrade it.
Selecting a Right Wood Therapy Product
Picking a timber therapy picking the ideal timber therapy product is necessary to safeguard timber successfully in time. There are various kinds of items that can successfully preserving this product. One can make use of an item that penetrates deeply, such as oil, impregnation, or saturator.
A permeating treatment supplies extra reliable security than a product that transfers a movie on the surface, such as paint, varnish, or sealant. While a film-forming product might seem helpful originally, this is not constantly the instance in the long term.
They can end up cracking, flaking, splitting, or peeling off over the years. Infiltration, water, or humidity passes through the material, which comes to be poorly shielded. It is after that vital to sand or strip the surface area of the timber to bare it again to be protected.
Silicones are extensively made use of in timber waterproofing items. These dangerous materials need to be stayed clear of similarly as oil solvents, which are still existing in many products. They are not harmless to the customer, the setting, or nature. It is far better to pick a bio-sourced item of plant beginning that is consistent with this all-natural product.

Preserve Routinely for Adequate Security.
Maintain forever defense keep routinely for a sufficient defense, continues to be a procedure that ought to not be forgotten to perform. Regardless of the sort of waterproofing selected to preserve the wood, it is needed to keep it frequently so that the protection stays adequately effective in time.
Tedious preparation, sanding, gritting, or removing of the surface area can be avoided utilizing an oil, saturator, or impregnation. They have the particularity of safeguarding the product throughout its mass without creating a film externally that can exfoliate later.
A waterproofing agent’s function is to shield the timber from stains, marks, rings, as well as day-to-day wear and tear. It is generally associated with an anti UV representative that will certainly stop the timber from becoming also grey over time. It thus restricts the sensation of swelling or shrinking.
A non-film-forming water repellent has lots of benefits for protecting a wooden surface. It is extremely reliable against poor climate thanks to a barrier impact. Also, it continues to be very efficient in nurturing the wood in all its deepness to the material’s actual heart. It also safeguards the assistance from light, sunlight, as well as ultraviolet rays.
