Outdoor wood has 2 main opponents: UV (ultraviolet rays from sunlight) and also humidity. The first causes a type of shallow melt – like on our skin, resulting in little splits and also greying. Nothing dramatic, the damage is primarily visual, as well as the wood is not affected comprehensive. Home Furniture & Diy
Wetness postures far more serious troubles: if rainwater does not run or does not vaporize quickly, if the wood continues to be in contact with the ground or if the moisture can climb by capillary action, the wetness material of the timber will certainly allow the installment of lignivorous fungis that are precursors to rot and support strikes by wood-eating pests. Can chemical preservative therapies be avoided?
Long lasting Types, without Sapwood
Some normally sturdy varieties from our areas can be used without treatment when the timber is laid up and down (risk course 3) and enables excellent water drainage (cladding, home windows, shutters): specifically Douglas, larch, chestnut, oak, and grasshopper. Just the last 3 species are advised when the timber is laid horizontally (veranda or balcony boards) or touching the ground (threat class 4). These timbers have to additionally be picked and cut in such a method as to remove the sapwood, the peripheral part of the trunk abundant in sugars, which brings in wood-eating insects.

What Are the Benefits of Securing Your Wood?
Embellishes and Shields
Beyond maintaining the aesthetic element over time, making use of a timber oil or a saturator in the security of timber will certainly revive its original shade as well as improve the grain of the timber while maintaining its natural appearance.
Stabilizes the Wood
Fueling oil a wood permits enhancing its dimensional stability durably, thus reducing the sensations of contortion (tiling, swelling, as well as shrinkage), fracturing, or surface splitting.
Natural and Ecological
Selecting an “Oleobois” safety oil means selecting a healthy as well as eco-friendly remedy; the structure omits fungicides, turpentine, and also any oil derivatives regularly made use of (paraffin, white spirit, …).
Easy and Economical Upkeep
Upkeep is easy because once fueled oil; timber does not need to be removed or fined sand before improvement: a cleansing with black soap adhered to by a simple re-oiled surface area is enough. Home Furniture & Diy
Greying of The Timber
What Is Wood Graying?
Wood is a material almost composed of polysaccharides (cellulose as well as hemicelluloses) and also lignins that will be deteriorated under ultraviolet photons’ activity. This photodegradation of the lignins, which is also emphasized in the presence of water, is in charge of the advancement of the color of the wood. Greying is observed on the hardwood used outdoors without any physical defense and UV security. This sensation creates a change in the original shade of the raw timber with time, which has a tendency to become grey.
What Are the Repercussions of Greying?
Greying or graying, which is a very superficial phenomenon, only impacts the wood framework’s visual appeals. It does not suggest an architectural alteration and also does not influence the solidity of the material. The appearance of this phenomenon is restricted to the surface area of the timber. The loss of architectural toughness (which can reach the wreck of the product) is, for its part, as a result of assaults of biological beginning that affect the timber in its mass.
Is it feasible to prevent the greying of the timber without maintaining it?
NO – Without completing products as well as without upkeep, it would certainly be illusory to assert to be able to prevent the wood from greying.
Will the application of a finish protect against the wood from transforming gray?
YES – If this application is made consistently, it is possible to avoid this sensation. The hydrophobic nature of the oil strongly limits the timber’s affinity for water as well as for that reason postpones its activity. Home Furniture & Diy
Corrected and Thermo-Oiled Timber
Several current processes have made it possible to enhance the sturdiness as well as dimensional stability of other types significantly: these are high-temperature warmth therapies (210 to 250 ° C )in a number of stages, performed in special heating systems, either under an inert environment with nitrogen (remedied timber) or with water vapor shots (Finnish heat-treated lumber). The timber takes on an attractive brownish shade as well as comes to be hydrophobic and extremely resistant to fungal or insect assaults. The high temperature deteriorates these woods a little, which can not be utilized for structural purposes (generally in exterior siding, parquet, and balcony boards).
The so-called homeothermic procedure does not have this downside: the wood is only heated up to 130 ° C, with an immersion in a blend based on linseed oil and also vegetable oil derivatives, which permits a deep impregnation. This also guarantees a much longer resistance to greying and also does not call for regular upkeep. The process creators have actually started to market it in France: 3 makers in the wood market have actually already bought it, and others are in the pipe. The recent Wood-Protect process patented by Lapeyre as well as INRA-INPT in Toulouse is of the exact same kind, with impregnation by autoclave and then by soaking at 140 ° C in a blend of grease derivatives and also acetic acid.

High-temperature therapies make the wood wholly water resistant and also fungi resistant.
The wood is given a temperature level in between 210 ° C and also 250 ° C in unique stoves. It then changes shade to end up being darker. The main disadvantage is that it sheds its stamina. 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 in a linseed oil bathroom, and also drying out. Considering that the home heating temperature is lower than the previous technique, the timber is much less weak.
Researches have revealed that homeothermic heating is advantageous when done after boron therapy. Boron has anti-inflammatory properties. The issue is that it is not immune to washing. Thus, the homeothermic makes it feasible to fix the molecule and make the timber extra immune to fires, water, and shocks. To learn more regarding this technique, here is a doctoral thesis that was done on the subject.
Oils, Discolorations, as well as Paints
The sturdiness of specific species such as oak and also chestnut is mostly because of their high tannin web content. These are gradually washed out by rain, which is slightly acidic. Like various other varieties, oak as well as chestnut, therefore, call for surface area protection. Linseed oil with a little turpentine included – to be made use of in hot weather (it penetrates far better) – is timeless and cost-effective security, water-repellent, as well as hold-ups greying.
Organic wood spots, which are tinted however show the timber grain, give far better defense against UV rays thanks to the pigments they contain. Nonetheless, they should be renewed every 3 to 5 years for the south exteriors and every 8 to one decade for the north exteriors. Unlike paints, they do not need sanding before revival (a brush stroke is enough to remove the pigment dust). As for organic lacquer paints, they provide more sturdy defense given that they have fillers (particularly chalk) that form a whole screen against UV rays. It’s a little bit like sun creams; the protection depends on the screen’s high quality as well as the exposure. Home Furniture & Diy
Surface area Defense
To improve the toughness of outside timber naturally, go with a discolor, for example, a combination of linseed oil and turpentine. Some commercially available wood discolorations are tinted as well as offer mild UV protection. The advantage of this method is that no sanding is required.
For even better security, use natural lacquer paint. It will give optimal defense against ultraviolet rays– favor microporous paints containing chalk fillers to allow the wood breathe.
Protecting external wood naturally can be performed with a protective stain or heat therapy. The choice of method relies on the qualities that you want to customize. If certain wood types can be used without defense, they should be stained after a particular period due to the fact that the safety tannins will certainly have vanished. If you do not do this, you will certainly need to have an expert dampness treatment.
Safeguarding Timber from Water
Securing wood from water is a vital function of an exterior finish prior to any attractive aspect. It is recommended to conserve the material with paint, varnish, stain, saturator, or oil. It is essential to achieve an actual barrier impact, which must be water resistant if the timber is not to wear away as well rapidly.
This makes it feasible to protect all-natural, strong, raw, or veneered timber virtually with time. It is safeguarded to maintain for many years in the face of the various weather hostilities experienced. It is durably maintained from humidity, rain, bad weather condition, light, sun, and also ultraviolet rays, making it age too soon. Home Furniture & Diy
Remain Naturally Absorptive to Moisture
Remain moisture permeableStaying normally permeable to smoke is extremely essential. Timber is made up of plant fibers that have an outstanding affinity with water. It is, consequently, a delicate product that remains conveniently absorptive to water. It remains particularly conscious various liquids that penetrate it.
Wood absorbs very rapidly the humidity that exists in the ambient atmosphere. It takes in water prior to normally releasing it because it is a hygroscopic product. It stays in consistent equilibrium with its setting, whatever the moisture web content.
These different moisture variants go to the beginning of the common dimensional transformations of wood. They have the effect of creating deformations that can in some cases be significant. It works by swelling if the air is also humid. It shrinks when the environment becomes drier.
Rain, showers, thunderstorms, and also other bad weather condition that touch with the wood can cause the appearance of unattractive stains, streaks, drips, and halos. Dampness, infiltration, condensation, and also water vapor are likewise in charge of the premature aging of timber for many years. Home Furniture & Diy
Do Not Prevent Exchanges with The Outside World.
Do not stop exchanges with the outside not avoid communications with the outside; it should be respected. When you want to shield 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 impregnated by moisture if it is to last over the long term.
A wood treatment product can only be flawlessly appropriate if it values the different wetness exchanges. The wood must be able to remain to manage itself with its atmosphere. It is necessary to ensure that the film remains completely micro-porous to assure a good exchange efficiency.
On the other hand, impermeability as well as water rigidity should not be perplexed, which are extremely various notions. Waterproofing needs to be banned in the case of wood security. Making a wood completely watertight might trigger the product to rot in the long term.
Gas exchange, which controls the moisture content in the timber’s pores, have to never be protected against. A timber paint should enable the substrate to breathe without ever quiting the interior discharge to the exterior. It needs to simply avoid water from penetrating the heart of the timber, not to modify or weaken it.
Selecting a Right Wood Therapy Item
Choosing a timber therapy selecting the right timber therapy item is vital to protect timber effectively in time. There are different sorts of products that are capable of effectively preserving this product. One can utilize an item that penetrates deeply, such as oil, impregnation, or saturator.
A penetrating treatment provides much more reliable security than a product that transfers a film on the surface, such as paint, varnish, or sealant. Without a doubt, while a film-forming item might seem beneficial originally, this is not always the instance in the long term.
Undoubtedly, they can end up breaking, flaking, splitting, or peeling for many years. Seepage, water, or humidity passes through the material, which ends up being badly protected. It is after that necessary to sand or strip the surface of the timber to bare it again to be protected.
Silicones are commonly used in timber waterproofing products. These unsafe substances must be prevented in the same way as petroleum solvents, which are still existing in lots of items. They are not harmless to the customer, the setting, or nature. It is much better to select a bio-sourced product of plant origin that is consistent with this all-natural product. Home Furniture & Diy
Keep Regularly for Adequate Protection.
Maintain permanently protection maintain on a regular basis for a sufficient defense, continues to be a procedure that should not be failed to remember to perform. Despite the type of waterproofing picked to maintain the timber, it is essential to preserve it on a regular basis to make sure that the defense continues to be completely efficient with time.
Tedious preparation, sanding, gritting, or stripping of the surface can be stayed clear of using an oil, saturator, or impregnation. They have the particularity of shielding the material throughout its mass without developing a film externally that can flake off later.
A waterproofing agent’s function is to safeguard the timber from discolorations, marks, rings, and also everyday wear and tear. It is usually related to an anti UV representative that will certainly stop the timber from ending up being as well grey over time. It therefore limits the phenomenon of swelling or shrinkage.
A non-film-forming water repellent has numerous advantages for preserving a wood surface area. It is really reliable versus negative weather thanks to a barrier impact. It stays extremely effective in nourishing the wood in all its depth to the product’s very heart. It likewise secures the support from light, sun, and also ultraviolet rays. Home Furniture & Diy
