Outside timber has 2 primary adversaries: UV (ultraviolet rays from sunshine) and humidity. The first causes a sort of surface burn – like on our skin, resulting in small splits as well as greying. Absolutely nothing significant, the damages is mainly visual, as well as the wood is not impacted detailed. Open Main Plan Furniture Layout
Wetness poses much more severe issues: if rain does not run off or does not vaporize quickly, if the timber continues to be in contact with the ground or if the dampness can increase by capillary action, the moisture web content of the wood will certainly enable the installation of lignivorous fungi that are forerunners to rot and also favor assaults by wood-eating pests. Can chemical preservative therapies be stayed clear of?
Long lasting Types, without Sapwood
Some naturally long lasting types from our regions can be used without therapy when the wood is laid up and down (threat course 3) and also enables great water drainage (cladding, home windows, shutters): particularly Douglas, larch, chestnut, oak, as well as cicada. Just the last 3 types are suggested when the timber is laid flat (terrace or terrace boards) or in contact with the ground (danger class 4). These timbers must additionally be picked and also cut in such a means as to eliminate the sapwood, the peripheral part of the trunk rich in sugars, which attracts wood-eating pests.

What Are the Advantages of Safeguarding Your Timber?
Embellishes and also Secures
Past keeping the visual aspect with time, using a wood oil or a saturator in the defense of timber will certainly revitalize its initial shade and also improve the grain of the wood while maintaining its all-natural look.
Maintains the Wood
Fueling oil a wood enables boosting its dimensional stability durably, thus decreasing the phenomena of deformation (tiling, swelling, and also shrinkage), fracturing, or surface splitting.
Natural and also Ecological
Selecting an “Oleobois” safety oil means choosing a healthy as well as eco-friendly solution; the composition omits fungicides, turpentine, as well as any type of oil derivatives regularly made use of (paraffin, white spirit, …).
Easy and Economical Upkeep
Maintenance is simple due to the fact that as soon as fueled oil; wood does not require to be stripped or fined sand prior to remodelling: a cleaning with black soap complied with by a basic re-oiled surface area suffices. Open Main Plan Furniture Layout
Greying of The Timber
What Is Timber Graying?
Timber is a material virtually composed of polysaccharides (cellulose as well as hemicelluloses) and lignins that will certainly be weakened under ultraviolet photons’ activity. This photodegradation of the lignins, which is also accentuated in the presence of water, is in charge of the evolution of the shade of the wood. Greying is observed on the lumber made use of outdoors with no physical protection and UV protection. This phenomenon triggers a modification in the original shade of the raw timber with time, which tends to come to be gray.
What Are the Effects of Greying?
Greying or graying, which is a very surface phenomenon, just impacts the wooden structure’s looks. It does not show a structural change as well as does not impact the solidity of the material. The look of this sensation is restricted to the surface area of the wood. The loss of architectural toughness (which can go as far as the destroy of the product) is, for its component, due to attacks of organic beginning that influence the timber in its mass.
Is it feasible to stay clear of the greying of the wood without preserving it?
NO – Without ending up products and also without maintenance, it would certainly be illusory to claim to be able to stop the wood from greying.
Will the application of a finish stop the timber from transforming grey?
YES – If this application is made regularly, it is feasible to prevent this phenomenon. The hydrophobic nature of the oil strongly limits the timber’s fondness for water and also consequently delays its activity. Open Main Plan Furniture Layout
Remedied as well as Thermo-Oiled Timber
Several current processes have made it possible to improve the toughness and dimensional security of various other types dramatically: these are high-temperature warmth treatments (210 to 250 ° C )in numerous stages, performed in special heating systems, either under an inert ambience with nitrogen (fixed wood) or with water vapor shots (Finnish heat-treated lumber). The timber takes on an attractive brownish color as well as ends up being hydrophobic and also really immune to fungal or insect attacks. The high temperature weakens these timbers a little, which can not be utilized for structural objectives (generally in home siding, parquet, and also terrace boards).
The supposed homeothermic procedure does not have this downside: the wood is just heated up to 130 ° C, with an immersion in a blend based on linseed oil as well as vegetable oil derivatives, which enables a deep impregnation. This likewise guarantees a longer resistance to greying as well as does not need regular maintenance. The procedure developers have started to market it in France: 3 producers in the wood market have currently bought it, and also others are in the pipeline. The recent Wood-Protect procedure patented by Lapeyre and also INRA-INPT in Toulouse is of the very same type, with impregnation by autoclave and afterwards by saturating at 140 ° C in a mixture of grease by-products and acetic acid.

High-temperature treatments make the timber entirely water resistant as well as fungi resistant.
The timber is brought to a temperature in between 210 ° C as well as 250 ° C in unique ovens. It after that changes shade to end up being darker. The primary disadvantage is that it sheds its toughness. It can after that only be utilized for cladding or flooring.
Oleothermy is a treatment that contains 3 phases: home heating to 130 ° C in a rapeseed oil bathroom, cooling down in a linseed oil bath, and drying. Since the heating temperature level is lower than the previous technique, the wood is less weak.
Researches have actually revealed that homeothermic heating is helpful when done after boron treatment. Boron has anti-inflammatory residential properties. The trouble is that it is not immune to cleaning. Therefore, the homeothermic makes it possible to fix the particle as well as make the timber extra immune to fires, water, and also shocks. To learn more about this approach, right here is a doctoral thesis that was done on the topic.
Oils, Spots, and also Paints
The longevity of specific types such as oak and chestnut is generally as a result of their high tannin web content. These are gradually cleaned out by rainwater, which is slightly acidic. Like other varieties, oak and chestnut, for that reason, require surface security. Linseed oil with a little turpentine included – to be used in hot weather (it permeates better) – is classic and low-cost protection, water-repellent, and delays greying.
Organic timber discolorations, which are colored but show the timber grain, provide better protection versus UV rays thanks to the pigments they include. However, they need to be restored every 3 to 5 years for the south facades and also every 8 to 10 years for the north exteriors. Unlike paints, they do not call for sanding prior to renewal (a brush stroke suffices to get rid of the pigment dirt). As for organic lacquer paints, they offer more resilient protection because they contain fillers (particularly chalk) that develop a whole display against UV rays. It’s a little bit like sun creams; the protection depends on the display’s quality and also the direct exposure. Open Main Plan Furniture Layout
To enhance the sturdiness of exterior wood normally, choose a tarnish, as an example, a mix of linseed oil and turpentine. Some commercially available timber discolorations are tinted and also give minor UV protection. The advantage of this approach is that no sanding is needed.
For even much better protection, use natural lacquer paint. It will certainly supply ideal defense versus ultraviolet rays– prefer microporous paints including chalk fillers to let the wood breathe.
Securing external wood normally can be finished with a safety tarnish or warm therapy. The choice of method relies on the features that you desire to modify. If particular timber species can be used without protection, they need to be stained after a certain duration due to the fact that the protective tannins will certainly have gone away. If you do refrain this, you will have to have an expert dampness therapy.
Securing Wood from Water
Safeguarding wood from water is a vital function of an outside surface prior to any decorative aspect. It is suggested to save the product with paint, varnish, stain, saturator, or oil. Without a doubt, it is necessary to achieve an actual obstacle impact, which must be water-proof if the timber is not to degrade too swiftly.
This makes it possible to protect natural, strong, raw, or veneered wood virtually gradually. It is secured to keep for several years in the face of the numerous climatic aggressiveness came across. It is durably protected from humidity, rain, negative weather condition, light, sunlight, as well as ultraviolet rays, making it age prematurely. Open Main Plan Furniture Layout
Continue To Be Naturally Permeable to Dampness
Remain dampness permeableStaying naturally permeable to smoke is really crucial. Wood is comprised of plant fibers that have a superb affinity with water. It is, consequently, a fragile product that stays quickly absorptive to water. It continues to be especially conscious various liquids that permeate it.
Wood soaks up really promptly the moisture that exists in the ambient ambience. It absorbs water before naturally launching it since it is a hygroscopic material. It stays in consistent equilibrium with its environment, whatever the dampness content.
These various moisture variants go to the beginning of the common dimensional changes of wood. They have the effect of triggering deformations that can sometimes be considerable. It functions by swelling if the air is also damp. It reduces when the environment becomes drier.
Rain, showers, electrical storms, and also other negative weather condition that are in contact with the timber can trigger the appearance of unsightly discolorations, streaks, trickles, and halos. Wetness, infiltration, condensation, as well as water vapor are also in charge of the early aging of timber over the years. Open Main Plan Furniture Layout
Do Not Stop Exchanges with The Outdoors.
Do not stop exchanges with the outdoors not prevent communications with the outside; it has to be valued. When you wish to secure the timber, a water-repellent product has to be put on avoid water from permeating it. It must be made certain that it is not impregnated by dampness if it is to last over the long term.
A timber therapy product can only be flawlessly ideal if it appreciates the different moisture exchanges. The timber needs to be able to continue to control itself with its setting. It is essential to guarantee that the film continues to be adequately micro-porous to guarantee an excellent exchange effectiveness.
On the other hand, impermeability and also water tightness ought to not be perplexed, which are really different notions. Waterproofing must be prohibited in the case of wood security. Making a wood entirely watertight may trigger the material to rot in the long term.
Gas exchange, which controls the moisture web content in the wood’s pores, must never ever be prevented. A wood paint must allow the substratum to breathe without ever before stopping the interior emptying to the exterior. It needs to simply protect against water from permeating the heart of the wood, not to modify or deteriorate it.
Selecting a Right Timber Treatment Product
Selecting a timber therapy choosing the best timber treatment item is essential to safeguard timber efficiently with time. There are various kinds of products that can successfully maintaining this material. One can use an item that passes through deeply, such as oil, impregnation, or saturator.
A penetrating treatment provides much more reliable protection than a product that deposits a movie externally, such as paint, varnish, or sealer, for example. While a film-forming item may seem valuable originally, this is not constantly the situation in the long term.
Indeed, they can wind up breaking, flaking, breaking, or peeling over the years. Infiltration, water, or humidity permeates the product, which becomes improperly protected. It is then important to sand or strip the surface area of the timber to bare it again to be maintained.
Silicones are widely used in timber waterproofing items. These dangerous materials should be avoided in the same way as oil solvents, which are still existing in lots of items. They are not harmless to the customer, the setting, or nature. It is better to choose a bio-sourced item of plant beginning that follows this all-natural material. Open Main Plan Furniture Layout
Maintain Consistently for Adequate Defense.
Preserve completely defense preserve frequently for an adequate protection, remains an operation that must not be neglected to perform. No matter the sort of waterproofing picked to maintain the timber, it is essential to preserve it on a regular basis to ensure that the defense stays completely reliable over time.
Laborious prep work, sanding, gritting, or removing of the surface area can be avoided making use of an oil, saturator, or impregnation. They have the particularity of securing the material throughout its mass without producing a film externally that can flake off later.
A waterproofing representative’s feature is to secure the wood from stains, marks, rings, and everyday deterioration. It is generally connected with an anti UV agent that will prevent the wood from coming to be too grey over time. It thus limits the phenomenon of swelling or shrinking.
A non-film-forming water repellent has numerous advantages for maintaining a wood surface. It is extremely effective versus poor weather thanks to an obstacle effect. It stays really efficient in nurturing the wood in all its deepness to the product’s very heart. It additionally shields the assistance from light, sun, as well as ultraviolet rays.
