Outdoor wood has 2 main enemies: UV (ultraviolet rays from sunshine) as well as humidity. The first causes a type of shallow shed – like on our skin, causing tiny fractures and greying. Nothing remarkable, the damages is mainly visual, and also the timber is not affected comprehensive. House Plan Furniture Symbols
Moisture poses a lot more severe issues: if rain does not run or does not evaporate rapidly, if the wood remains touching the ground or if the wetness can rise by capillary activity, the wetness material of the timber will certainly allow the setup of lignivorous fungis that are forerunners to rot as well as favor strikes by wood-eating bugs. Can chemical preservative treatments be prevented?
Long lasting Types, without Sapwood
Some naturally long lasting types from our areas can be made use of without therapy when the timber is laid vertically (risk course 3) and enables good water drainage (cladding, home windows, shutters): in particular Douglas, larch, chestnut, oak, and also grasshopper. Only the last 3 types are advised when the timber is laid horizontally (terrace or balcony boards) or in contact with the ground (risk course 4). These timbers have to also be chosen as well as cut in such a means regarding remove the sapwood, the peripheral part of the trunk rich in sugars, which brings in wood-eating insects.

What Are the Advantages of Shielding Your Timber?
Embellishes and also Shields
Beyond preserving the aesthetic aspect over time, making use of a wood oil or a saturator in the security of wood will revive its original shade and also boost the grain of the wood while preserving its all-natural appearance.
Maintains the Wood
Fueling oil a timber enables enhancing its dimensional stability durably, thus decreasing the sensations of contortion (tiling, swelling, and also shrinking), cracking, or surface splitting.
All-natural and also Ecological
Choosing an “Oleobois” safety oil means choosing a healthy and environmentally friendly service; the make-up leaves out fungicides, turpentine, and any petroleum derivatives frequently used (paraffin, white spirit, …).
Easy as well as Economical Upkeep
Maintenance is simple due to the fact that once oiled; wood does not need to be removed or sanded before remodelling: a cleansing with black soap adhered to by an easy re-oiled surface area is enough. House Plan Furniture Symbols
Greying of The Wood
What Is Wood Graying?
Timber is a product virtually composed of polysaccharides (cellulose and also hemicelluloses) and lignins that will certainly be deteriorated under ultraviolet photons’ activity. This photodegradation of the lignins, which is also accentuated in the existence of water, is in charge of the advancement of the color of the wood. Greying is observed on the lumber made use of outdoors without any physical protection and also UV defense. This phenomenon causes an adjustment in the original color of the raw timber gradually, which tends to become grey.
What Are the Repercussions of Greying?
Greying or graying, which is a very superficial phenomenon, only affects the wood framework’s appearances. It does not show a structural change as well as does not impact the strength of the product. The appearance of this phenomenon is limited to the surface area of the timber. The loss of structural resilience (which can go as far as the mess up of the material) is, for its part, due to strikes of biological beginning that affect the timber in its mass.
Is it feasible to prevent the greying of the wood without keeping it?
NO – Without finishing items and without upkeep, it would certainly be illusory to claim to be able to avoid the wood from greying.
Will the application of a coating stop the wood from turning gray?
YES – If this application is made on a regular basis, it is possible to prevent this phenomenon. The hydrophobic nature of the oil strongly restricts the timber’s affinity for water and also consequently delays its activity. House Plan Furniture Symbols
Rectified and also Thermo-Oiled Wood
Several current procedures have actually made it feasible to improve the sturdiness as well as dimensional stability of various other species substantially: these are high-temperature warmth therapies (210 to 250 ° C )in a number of phases, executed in unique heating systems, either under an inert atmosphere with nitrogen (fixed wood) or with water vapor shots (Finnish heat-treated lumber). The timber takes on a beautiful brownish shade and comes to be hydrophobic and very resistant to fungal or insect strikes. The high temperature level weakens these woods a little, which can not be used for structural objectives (generally in house siding, parquet, and also balcony boards).
The supposed homeothermic process does not have this downside: the wood is just warmed up to 130 ° C, with an immersion in a blend based upon linseed oil as well as vegetable oil by-products, which enables a deep impregnation. This also makes sure a longer resistance to greying and does not need regular maintenance. The procedure creators have actually begun to market it in France: 3 manufacturers in the timber sector have actually currently bought it, and also others remain in the pipe. The recent 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 saturating at 140 ° C in a mix of grease by-products and acetic acid.

High-temperature therapies make the wood completely water-proof as well as fungus resistant.
The timber is offered a temperature level between 210 ° C as well as 250 ° C in unique stoves. It then changes color to end up being darker. The major disadvantage is that it loses its toughness. It can then only be made use of for cladding or flooring.
Oleothermy is a treatment that includes 3 phases: heating to 130 ° C in a rapeseed oil bath, cooling down in a linseed oil bath, and also drying out. Because the heating temperature is less than the previous approach, the timber is much less brittle.
Research studies have revealed that homeothermic heating is helpful when done after boron therapy. Boron has anti-inflammatory residential properties. The trouble is that it is not resistant to cleaning. Hence, the homeothermic makes it feasible to deal with the molecule as well as make the wood extra immune to flames, water, and shocks. To learn more about this technique, below is a doctoral thesis that was done on the topic.
Oils, Discolorations, and also Paints
The toughness of certain varieties such as oak and also chestnut is mainly as a result of their high tannin web content. Nevertheless, these are gradually washed out by rainwater, which is a little acidic. Like other varieties, oak and also chestnut, therefore, call for surface protection. Linseed oil with a little turpentine included – to be made use of in heat (it permeates better) – is classic and inexpensive defense, water-repellent, and delays greying.
Organic wood stains, which are colored however show the timber grain, give better security versus UV rays thanks to the pigments they include. They must be restored every 3 to 5 years for the south exteriors and every 8 to 10 years for the north facades. Unlike paints, they do not need sanding prior to renewal (a brush stroke is enough to get rid of the pigment dust). When it comes to natural lacquer paints, they give even more resilient defense because they contain fillers (especially chalk) that form a whole screen against UV rays. It’s a bit like sun creams; the security depends upon the display’s top quality and the exposure. House Plan Furniture Symbols
Surface area Defense
To enhance the resilience of outside timber normally, go with a discolor, for instance, a mixture of linseed oil as well as turpentine. Some readily available timber spots are colored as well as supply slight UV security. The advantage of this technique is that no sanding is required.
For even far better protection, use natural lacquer paint. It will supply optimal defense versus ultraviolet rays– favor microporous paints containing chalk fillers to let the timber breathe.
Safeguarding exterior timber normally can be finished with a safety stain or warm treatment. The option of approach relies on the features that you desire to change. If particular wood species can be used without protection, they must be stained after a certain period because the protective tannins will have vanished. If you do not do this, you will certainly have to have an expert wetness treatment.
Safeguarding Timber from Water
Protecting wood from water is a crucial function of an outside coating before any kind of attractive aspect. It is suggested to save the material with paint, varnish, tarnish, saturator, or oil. Undoubtedly, it is important to attain an actual barrier effect, which need to be water resistant if the timber is not to deteriorate too rapidly.
This makes it possible to preserve all-natural, strong, raw, or veneered wood basically in time. It is safeguarded to maintain for several years when faced with the numerous weather aggressions encountered. It is durably preserved from moisture, rainfall, poor weather condition, light, sun, and also ultraviolet rays, making it age prematurely. House Plan Furniture Symbols
Remain Normally Permeable to Moisture
Continue to be dampness permeableStaying normally absorptive to smoke is very crucial. Timber is made up of plant fibers that have an excellent fondness with water. It is, therefore, a vulnerable product that stays conveniently absorptive to water. It remains specifically sensitive to numerous liquids that permeate it.
Timber soaks up very promptly the moisture that exists in the ambient atmosphere. It soaks up water before normally releasing it because it is a hygroscopic material. It remains in consistent stability with its atmosphere, whatever the wetness material.
These various humidity variants go to the beginning of the normal dimensional transformations of wood. They have the effect of creating contortions that can sometimes be substantial. It functions by swelling if the air is also moist. It diminishes when the environment becomes drier.
Rain, showers, electrical storms, and also other negative climate that are in contact with the wood can trigger the look of undesirable discolorations, streaks, leaks, and halos. Moisture, seepage, condensation, and water vapor are likewise responsible for the premature aging of wood over the years. House Plan Furniture Symbols
Do Not Stop Exchanges with The Outdoors.
Do not protect against exchanges with the outdoors not prevent interactions with the exterior; it needs to be appreciated. When you wish to protect the timber, a water-repellent product should be related to avoid water from penetrating it. It needs to be made certain that it is not impregnated by dampness if it is to last over the long term.
A wood therapy product can just be flawlessly appropriate if it appreciates the different wetness exchanges. The timber needs to have the ability to continue to regulate itself with its setting. It is important to make sure that the film continues to be sufficiently micro-porous to guarantee an excellent exchange efficiency.
On the other hand, impermeability as well as water tightness should not be puzzled, which are really various notions. Waterproofing has to be restricted in the case of wood protection. Making a timber totally watertight may create the material to rot in the long term.
Gas exchange, which manages the moisture web content in the wood’s pores, must never be prevented. A timber paint must enable the substrate to take a breath without ever stopping the inner evacuation to the outside. It should simply stop water from penetrating the heart of the timber, not to alter or weaken it.
Picking a Right Timber Treatment Product
Choosing a wood treatment selecting the best wood treatment item is essential to secure wood successfully gradually. There are various types of items that can efficiently protecting this product. One can use a product that permeates deeply, such as oil, impregnation, or saturator.
A passing through treatment gives a lot more effective protection than an item that transfers a movie on the surface, such as paint, varnish, or sealer, as an example. While a film-forming item might appear useful initially, this is not always the case in the long term.
They can finish up breaking, flaking, breaking, or peeling off over the years. Infiltration, water, or moisture passes through the material, which ends up being improperly protected. It is then necessary to sand or strip the surface of the timber to bare it again to be preserved.
Silicones are widely used in timber waterproofing items. These dangerous substances must be prevented in the same way as petroleum solvents, which are still present in several products. They are not safe to the customer, the environment, or nature. It is much better to choose a bio-sourced item of plant origin that is consistent with this natural material.

Preserve Consistently for Adequate Protection.
Preserve completely defense keep on a regular basis for an ample defense, continues to be an operation that needs to not be failed to remember to carry out. Regardless of the kind of waterproofing chosen to preserve the timber, it is necessary to keep it consistently to make sure that the defense stays sufficiently effective with time.
Laborious preparation, sanding, gritting, or stripping of the surface can be stayed clear of making use of an oil, saturator, or impregnation. They have the particularity of safeguarding the material throughout its mass without producing a film on the surface that can exfoliate later.
A waterproofing agent’s feature is to protect the timber from stains, marks, rings, and also everyday damage. It is generally connected with an anti UV representative that will certainly prevent the timber from becoming too grey in the long run. It hence limits the sensation of swelling or contraction.
A non-film-forming water repellent has many advantages for maintaining a wood surface area. It is extremely efficient versus bad weather thanks to an obstacle impact. Likewise, it remains extremely effective in nurturing the wood in all its depth to the product’s very heart. It also safeguards the support from light, sun, and ultraviolet rays.
