Outside wood has 2 primary enemies: UV (ultraviolet rays from sunshine) and moisture. The first causes a type of shallow melt – like on our skin, causing little fractures and greying. Nothing significant, the damages is mostly aesthetic, and also the timber is not affected in depth. Lawn Furniture Plan
Wetness postures a lot more extreme troubles: if rainwater does not escape or does not vaporize promptly, if the wood remains touching the ground or if the dampness can rise by capillary action, the dampness web content of the timber will certainly enable the installment of lignivorous fungi that are forerunners to rot and also support assaults by wood-eating bugs. Can chemical preservative therapies be prevented?
Resilient Species, without Sapwood
Some normally long lasting species from our regions can be made use of without therapy when the wood is laid up and down (risk class 3) and permits excellent water drainage (cladding, windows, shutters): specifically Douglas, larch, chestnut, oak, and grasshopper. Just the last 3 types are advised when the wood is laid horizontally (veranda or terrace boards) or touching the ground (danger class 4). These woods have to likewise be selected and cut in such a means as to eliminate the sapwood, the peripheral part of the trunk rich in sugars, which attracts wood-eating pests. Lawn Furniture Plan
What Are the Benefits of Securing Your Wood?
Embellishes as well as Protects
Past preserving the visual element over time, using a timber oil or a saturator in the defense of wood will certainly revive its original shade as well as enhance the grain of the timber while maintaining its all-natural appearance.
Supports the Timber
Oiling a wood enables improving its dimensional security durably, hence lowering the sensations of contortion (tiling, swelling, as well as shrinking), splitting, or surface area splitting.
Natural and Ecological
Picking an “Oleobois” protective oil means choosing a healthy and balanced and also environmentally friendly solution; the structure excludes fungicides, turpentine, as well as any oil by-products frequently made use of (paraffin, white spirit, …).
Easy and Economical Upkeep
Upkeep is very easy since when fueled oil; wood does not need to be stripped or sanded prior to restoration: a cleaning with black soap complied with by an easy re-oiled surface suffices. Lawn Furniture Plan
Greying of The Wood
What Is Wood Graying?
Wood is a material almost comprised of polysaccharides (cellulose as well as hemicelluloses) and lignins that will be deteriorated under ultraviolet photons’ action. This photodegradation of the lignins, which is additionally accentuated in the existence of water, is in charge of the advancement of the color of the wood. Greying is observed on the timber utilized outdoors with no physical security as well as UV defense. This phenomenon triggers a modification in the original shade of the raw timber over time, which tends to come to be grey.
What Are the Consequences of Greying?
Greying or graying, which is a really superficial sensation, only affects the wood structure’s aesthetic appeals. It does not suggest an architectural modification as well as does not influence the solidity of the material. The appearance of this phenomenon is limited to the surface area of the timber. The loss of architectural longevity (which can go as far as the destroy of the material) is, for its part, due to attacks of biological beginning that influence the timber in its mass.
Is it possible to stay clear of the greying of the timber without preserving it?
NO – Without completing items and without maintenance, it would be illusory to declare to be able to avoid the timber from greying.
Will the application of a coating avoid the timber from transforming grey?
YES – If this application is made routinely, it is possible to prevent this sensation. The hydrophobic nature of the oil strongly limits the wood’s fondness for water as well as as a result delays its activity. Lawn Furniture Plan
Fixed and also Thermo-Oiled Wood
Several current procedures have made it feasible to improve the toughness and dimensional security of various other varieties significantly: these are high-temperature warm treatments (210 to 250 ° C )in numerous phases, accomplished in special heaters, either under an inert environment with nitrogen (corrected timber) or with water vapor injections (Finnish heat-treated lumber). The timber takes on a beautiful brown color and also comes to be hydrophobic and very immune to fungal or insect assaults. Nonetheless, the high temperature compromises these timbers a little, which can not be made use of for architectural purposes (mostly in home siding, parquet, and balcony boards).
The so-called homeothermic procedure does not have this disadvantage: the timber is only warmed up to 130 ° C, with an immersion in a combination based on linseed oil and vegetable oil derivatives, which permits a deep impregnation. This likewise makes sure a much longer resistance to greying as well as does not require regular maintenance. The process makers have begun to market it in France: three makers in the timber industry have actually currently bought it, as well as others remain in the pipeline. The current Wood-Protect process patented by Lapeyre and also INRA-INPT in Toulouse is of the very same kind, with impregnation by autoclave and afterwards by soaking at 140 ° C in a combination of grease derivatives and also acetic acid.

High-temperature treatments make the wood wholly water-proof and fungus resistant.
The timber is brought to a temperature level between 210 ° C as well as 250 ° C in unique stoves. It after that alters color to come to be darker. The main drawback is that it loses its strength. It can then only be used for cladding or floor covering.
Oleothermy is a treatment that contains 3 phases: heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bathroom, and also drying. Considering that the home heating temperature level is lower than the previous approach, the timber is less breakable.
Research studies have revealed that homeothermic heating is beneficial when done after boron therapy. Boron has anti-inflammatory buildings. The trouble is that it is not immune to washing. Hence, the homeothermic makes it possible to repair the molecule as well as make the timber extra immune to fires, water, as well as shocks. To get more information about this method, right here is a doctoral thesis that was done on the topic.
Oils, Discolorations, as well as Paints
The longevity of specific types such as oak as well as chestnut is generally because of their high tannin content. These are gradually cleaned out by rain, which is a little acidic. Like various other species, oak and chestnut, consequently, call for surface area protection. Linseed oil with a little turpentine included – to be made use of in hot weather (it penetrates much better) – is traditional as well as affordable defense, water-repellent, and also delays greying.
Organic wood stains, which are tinted but reveal the timber grain, supply better protection against UV rays thanks to the pigments they contain. Nevertheless, they need to be restored 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 require sanding before renewal (a brush stroke is enough to remove the pigment dirt). When it comes to natural lacquer paints, they give even more sturdy defense considering that they contain fillers (particularly chalk) that develop a whole screen against UV rays. It’s a bit like sun creams; the protection relies on the screen’s quality and the exposure. Lawn Furniture Plan
To improve the durability of outdoor wood naturally, choose a stain, for instance, a combination of linseed oil and turpentine. Some readily available wood discolorations are colored and also offer small UV protection. The advantage of this method is that no sanding is needed.
For also much better protection, apply natural lacquer paint. It will supply ideal protection against ultraviolet rays– favor microporous paints consisting of chalk fillers to allow the timber take a breath.
Protecting exterior timber naturally can be performed with a protective discolor or warm treatment. The choice of method depends upon the features that you want to change. If certain timber species can be used without defense, they should be stained after a particular period because the protective tannins will have gone away. If you do not do this, you will need to have a professional wetness treatment.
Securing Timber from Water
Safeguarding timber from water is a necessary feature of an exterior surface before any ornamental element. It is advised to conserve the product with paint, varnish, tarnish, saturator, or oil. It is important to achieve a genuine barrier impact, which have to be waterproof if the timber is not to wear away also quickly.
This makes it feasible to maintain all-natural, solid, raw, or veneered timber essentially gradually. It is safeguarded to maintain for many years when faced with the numerous weather aggressiveness came across. It is durably maintained from humidity, rain, poor climate, light, sunlight, as well as ultraviolet rays, making it age too soon. Lawn Furniture Plan
Stay Naturally Absorptive to Dampness
Continue to be wetness permeableStaying naturally permeable to smoke is very important. Timber is made up of plant fibers that have an outstanding affinity with water. It is, therefore, a breakable product that remains easily permeable to water. It stays especially sensitive to numerous liquids that permeate it.
Timber takes in very swiftly the humidity that is present in the ambient ambience. It takes in water prior to naturally launching it due to the fact that it is a hygroscopic product. It continues to be in consistent stability with its setting, whatever the dampness content.
These various moisture variations are at the origin of the typical dimensional transformations of timber. They have the result of creating contortions that can often be significant. It functions by swelling if the air is too humid. It diminishes when the ambience comes to be drier.
Rainfall, showers, thunderstorms, as well as other poor weather that touch with the timber can create the look of unsightly spots, streaks, trickles, as well as halos. Wetness, seepage, condensation, as well as water vapor are likewise responsible for the early aging of wood over the years. Lawn Furniture Plan
Do Not Prevent Exchanges with The Outside World.
Do not protect against exchanges with the outdoors not avoid interactions with the outside; it needs to be respected. When you intend to secure the timber, a water-repellent product must be applied to stay clear of water from penetrating it. It must be guaranteed that it is not fertilized by wetness if it is to last over the long term.
A wood treatment item can just be flawlessly appropriate if it values the various dampness exchanges. The wood must be able to remain to regulate itself with its setting. It is vital to ensure that the film stays adequately micro-porous to ensure a great exchange effectiveness.
On the other hand, impermeability and also water tightness should not be puzzled, which are really different concepts. Waterproofing must be restricted in the case of timber security. Making a wood totally watertight might cause the material to rot in the long term.
Gas exchange, which regulates the dampness web content in the timber’s pores, must never ever be protected against. A timber paint need to allow the substrate to take a breath without ever before quiting the internal discharge to the exterior. It must just stop water from penetrating the heart of the timber, not to alter or deteriorate it.
Choosing a Right Timber Therapy Item
Picking a timber treatment picking the ideal timber therapy product is necessary to protect timber efficiently with time. There are different kinds of items that can efficiently preserving this product. One can make use of a product that permeates deeply, such as oil, impregnation, or saturator.
A penetrating therapy gives a lot more reliable security than a product that transfers a movie on the surface, such as paint, varnish, or sealer, for example. While a film-forming item may seem valuable originally, this is not always the case in the lengthy term.
They can finish up breaking, flaking, cracking, or peeling off over the years. Seepage, water, or humidity permeates the product, which becomes inadequately protected. It is then essential to sand or strip the surface of the wood to bare it once again to be preserved.
Silicones are commonly used in wood waterproofing products. These damaging substances need to be prevented similarly as petroleum solvents, which are still existing in numerous items. They are not safe to the customer, the setting, or nature. It is far better to choose a bio-sourced item of plant origin that follows this all-natural product. Lawn Furniture Plan
Keep Regularly for Adequate Security.
Preserve completely defense maintain regularly for a sufficient protection, stays a procedure that must not be neglected to execute. Regardless of the type of waterproofing selected to preserve the wood, it is needed to maintain it regularly to make sure that the security stays adequately effective in time.
Laborious prep work, fining sand, gritting, or stripping of the surface area can be stayed clear of utilizing an oil, saturator, or impregnation. They have the particularity of shielding the product throughout its mass without creating a movie on the surface that can flake off later.
A waterproofing agent’s function is to protect the timber from discolorations, marks, rings, and also everyday wear and tear. It is normally related to an anti UV agent that will certainly stop the timber from becoming too grey in the future. It therefore limits the sensation of swelling or shrinkage.
A non-film-forming water repellent has numerous benefits for maintaining a wooden surface area. It is really effective against poor climate thanks to a barrier result. It remains really effective in nurturing the timber in all its deepness to the material’s actual heart. It additionally protects the support from light, sunlight, and also ultraviolet rays.
