Exterior timber has two major opponents: UV (ultraviolet rays from sunshine) and also moisture. The first causes a kind of superficial shed – like on our skin, resulting in small fractures and greying. Absolutely nothing remarkable, the damage is mainly aesthetic, and also the timber is not affected detailed. Open Floor Plan Room Has Tv And Floating Furniture
Moisture presents much more serious troubles: if rain does not run or does not vaporize promptly, if the timber remains touching the ground or if the dampness can rise by capillary action, the wetness content of the timber will allow the setup of lignivorous fungis that are forerunners to rot and also favor strikes by wood-eating insects. Can chemical preservative treatments be avoided?
Durable Types, without Sapwood
Some naturally durable types from our regions can be utilized without therapy when the wood is laid vertically (danger class 3) and allows good water drain (cladding, windows, shutters): specifically Douglas, larch, chestnut, oak, as well as grasshopper. Just the last three varieties are recommended when the timber is laid flat (veranda or terrace boards) or in contact with the ground (risk class 4). These woods should likewise be chosen and also cut in such a method regarding remove the sapwood, the outer part of the trunk abundant in sugars, which attracts wood-eating pests.

What Are the Benefits of Shielding Your Timber?
Embellishes and Shields
Beyond keeping the visual element gradually, utilizing a wood oil or a saturator in the protection of timber will revitalize its original color and also improve the grain of the timber while maintaining its natural look.
Stabilizes the Wood
Fueling oil a timber allows improving its dimensional stability durably, thus decreasing the sensations of contortion (tiling, swelling, and shrinking), cracking, or surface splitting.
All-natural as well as Ecological
Choosing an “Oleobois” protective oil implies choosing a healthy and balanced as well as environmentally friendly option; the composition leaves out fungicides, turpentine, and also any type of oil derivatives frequently used (paraffin, white spirit, …).
Easy and Economical Upkeep
Maintenance is easy because when fueled oil; wood does not need to be removed or sanded prior to remodelling: a cleansing with black soap complied with by a straightforward re-oiled surface suffices. Open Floor Plan Room Has Tv And Floating Furniture
Greying of The Wood
What Is Timber Graying?
Wood is a material virtually made up of polysaccharides (cellulose and hemicelluloses) and lignins that will certainly be broken down under ultraviolet photons’ activity. This photodegradation of the lignins, which is additionally highlighted in the presence of water, is in charge of the advancement of the color of the timber. Greying is observed on the lumber used outdoors with no physical defense as well as UV defense. This sensation triggers an adjustment in the original color of the raw timber over time, which tends to end up being grey.
What Are the Consequences of Greying?
Greying or graying, which is a really surface sensation, only impacts the wooden framework’s appearances. It does not indicate an architectural alteration and does not influence the solidity of the product. The appearance of this phenomenon is restricted to the surface of the timber. The loss of architectural sturdiness (which can reach the destroy of the product) is, for its part, as a result of attacks of organic beginning that influence the wood in its mass.
Is it feasible to prevent the greying of the timber without preserving it?
NO – Without finishing products and also without upkeep, it would certainly be imaginary to claim to be able to avoid the wood from greying.
Will the application of a coating stop the wood from transforming grey?
YES – If this application is made frequently, it is feasible to prevent this phenomenon. The hydrophobic nature of the oil highly limits the wood’s fondness for water as well as for that reason postpones its activity. Open Floor Plan Room Has Tv And Floating Furniture
Corrected and Thermo-Oiled Wood
Several recent processes have made it feasible to boost the toughness as well as dimensional security of other varieties considerably: these are high-temperature heat therapies (210 to 250 ° C )in a number of phases, carried out in special furnaces, either under an inert environment with nitrogen (corrected timber) or with water vapor injections (Finnish heat-treated lumber). The timber takes on a beautiful brownish color and becomes hydrophobic as well as really resistant to fungal or insect attacks. The high temperature level weakens these woods a little, which can not be used for structural purposes (mainly in house siding, parquet, as well as balcony boards).
The supposed homeothermic process does not have this drawback: the timber is just warmed up to 130 ° C, with an immersion in a mix based on linseed oil and also grease derivatives, which allows a deep impregnation. This likewise makes sure a much longer resistance to greying and does not require routine upkeep. The procedure creators have started to market it in France: three producers in the wood market have currently bought it, and also others are in the pipe. The recent Wood-Protect process patented by Lapeyre and also INRA-INPT in Toulouse is of the very same type, with impregnation by autoclave and then by saturating at 140 ° C in a mixture of grease by-products and acetic acid.

High-temperature therapies make the timber entirely waterproof and fungi resistant.
The wood is brought to a temperature level between 210 ° C and also 250 ° C in special ovens. It then alters shade to end up being darker. The main negative aspect is that it loses its stamina. It can after that just be used for cladding or floor covering.
Oleothermy is a treatment that consists of 3 stages: home heating to 130 ° C in a rapeseed oil bath, cooling in a linseed oil bathroom, and drying. Considering that the home heating temperature level is lower than the previous method, the timber is less breakable.
Researches have actually shown that homeothermic heating is advantageous when done after boron therapy. Boron has anti-inflammatory buildings. The issue is that it is not resistant to washing. Hence, the homeothermic makes it possible to take care of the molecule and make the timber more resistant to fires, water, and shocks. To read more about this technique, right here is a doctoral thesis that was done on the subject.
Oils, Spots, and Paints
The sturdiness of certain varieties such as oak and chestnut is mostly because of their high tannin web content. These are gradually washed out by rain, which is a little acidic. Like various other types, oak and chestnut, consequently, call for surface area protection. Linseed oil with a little turpentine included – to be utilized in hot weather (it permeates better) – is classic and also inexpensive defense, water-repellent, and delays greying.
Organic timber spots, which are colored but show the timber grain, give far better security versus UV rays thanks to the pigments they have. They should be restored 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 prior to renewal (a brush stroke suffices to eliminate the pigment dirt). As for organic lacquer paints, they provide even more resilient security because they consist of fillers (especially chalk) that form an entire display versus UV rays. It’s a little bit like sun creams; the protection depends on the screen’s quality as well as the direct exposure. Open Floor Plan Room Has Tv And Floating Furniture
To boost the toughness of outside wood naturally, select a discolor, for example, a mixture of linseed oil and turpentine. Some commercially readily available wood stains are tinted and also offer slight UV security. The benefit of this technique is that no sanding is needed.
For also better defense, apply organic lacquer paint. It will certainly provide ideal protection against ultraviolet rays– favor microporous paints having chalk fillers to let the wood take a breath.
Securing exterior wood naturally can be finished with a safety discolor or heat therapy. The selection of method depends upon the attributes that you desire to change. If particular timber types can be used without protection, they should be stained after a particular period since the protective tannins will have disappeared. If you do refrain from doing this, you will certainly have to have a professional wetness treatment.
Securing Timber from Water
Safeguarding timber from water is a necessary function of an outside surface prior to any type of attractive element. It is suggested to save the material with paint, varnish, discolor, saturator, or oil. Undoubtedly, it is vital to achieve a real barrier result, which must be waterproof if the wood is not to weaken too rapidly.
This makes it possible to protect natural, strong, raw, or veneered timber essentially over time. It is shielded to maintain for years in the face of the different climatic aggressiveness experienced. It is durably preserved from moisture, rainfall, negative climate, light, sunlight, as well as ultraviolet rays, making it age prematurely. Open Floor Plan Room Has Tv And Floating Furniture
Remain Normally Permeable to Wetness
Remain moisture permeableStaying normally absorptive to smoke is extremely vital. Wood is made up of plant fibers that have a superb affinity with water. It is, consequently, a vulnerable material that stays easily absorptive to water. It continues to be specifically sensitive to different liquids that permeate it.
Timber takes in very rapidly the moisture that exists in the ambient atmosphere. It absorbs water before naturally releasing it due to the fact that it is a hygroscopic product. It remains in constant balance with its environment, whatever the dampness web content.
These different humidity variations are at the origin of the typical dimensional makeovers of timber. They have the effect of causing contortions that can sometimes be considerable. It works by swelling if the air is too humid. It reduces when the environment becomes drier.
Rain, showers, thunderstorms, and also various other negative weather condition that touch with the timber can trigger the appearance of unpleasant discolorations, streaks, drips, and also halos. Dampness, infiltration, condensation, and also water vapor are also in charge of the premature aging of timber for many years. Open Floor Plan Room Has Tv And Floating Furniture
Do Not Protect against Exchanges with The Outside World.
Do not protect against exchanges with the outside not prevent interactions with the exterior; it needs to be respected. When you intend to secure the timber, a water-repellent product must be related to stay clear of water from penetrating 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 only be flawlessly ideal if it respects the different moisture exchanges. The wood must have the ability to continue to regulate itself with its setting. It is important to ensure that the movie continues to be sufficiently micro-porous to guarantee a good exchange efficiency.
On the other hand, impermeability as well as water tightness ought to not be puzzled, which are really various concepts. Waterproofing must be restricted when it comes to wood security. Making a timber totally watertight might create the material to rot in the long-term.
Gas exchange, which controls the dampness web content in the wood’s pores, have to never be avoided. A timber paint need to enable the substrate to take a breath without ever stopping the inner discharge to the outside. It needs to just protect against water from penetrating the heart of the timber, not to alter or weaken it.
Selecting a Right Timber Therapy Product
Picking a timber treatment selecting the appropriate timber therapy item is essential to secure timber efficiently over time. There are various kinds of items that can successfully preserving this material. One can use an item that penetrates deeply, such as oil, impregnation, or saturator.
A permeating treatment provides more efficient security than an item that transfers a film externally, such as paint, varnish, or sealant, as an example. Without a doubt, while a film-forming item might seem useful originally, this is not always the instance in the long-term.
They can end up cracking, flaking, breaking, or peeling off over the years. Infiltration, water, or humidity penetrates the product, which becomes badly shielded. It is after that important to sand or strip the surface area of the wood to bare it once again to be preserved.
Silicones are widely made use of in timber waterproofing items. These harmful materials ought to be stayed clear of in the same way as petroleum solvents, which are still existing in several products. They are not safe to the user, the environment, or nature. It is much better to pick a bio-sourced item of plant beginning that is consistent with this all-natural product. Open Floor Plan Room Has Tv And Floating Furniture
Preserve Frequently for Adequate Security.
Preserve permanently security preserve on a regular basis for a sufficient protection, remains a procedure that ought to not be forgotten to execute. Regardless of the type of waterproofing selected to protect the timber, it is essential to maintain it frequently to ensure that the protection continues to be adequately reliable with time.
Laborious preparation, sanding, gritting, or stripping 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 developing a movie on the surface that can flake off afterward.
A waterproofing representative’s feature is to secure the timber from discolorations, marks, rings, as well as daily damage. It is generally related to an anti UV representative that will avoid the wood from ending up being as well grey in the future. It hence restricts the sensation of swelling or shrinking.
A non-film-forming water repellent has numerous advantages for maintaining a wooden surface. It is really reliable against poor climate thanks to an obstacle result. Likewise, it continues to be really efficient in nourishing the timber in all its depth to the material’s very heart. It likewise shields the assistance from light, sun, and ultraviolet rays.
