Exterior timber has 2 main enemies: UV (ultraviolet rays from sunshine) and also moisture. The first causes a type of shallow shed – like on our skin, resulting in tiny fractures and also greying. Nothing significant, the damage is generally aesthetic, and also the wood is not impacted comprehensive. Diy Repurposed Furniture Blog
Dampness presents a lot more severe troubles: if rainwater does not run or does not vaporize swiftly, if the wood continues to be in contact with the ground or if the wetness can rise by capillary action, the dampness web content of the wood will enable the setup of lignivorous fungis that are precursors to rot as well as support assaults by wood-eating bugs. Can chemical preservative treatments be stayed clear of?
Resilient Species, without Sapwood
Some naturally durable species from our regions can be made use of without treatment when the wood is laid vertically (threat course 3) as well as allows excellent water drainage (cladding, windows, shutters): specifically Douglas, larch, chestnut, oak, and also grasshopper. Only the last three varieties are recommended when the wood is laid horizontally (veranda or balcony boards) or in contact with the ground (risk class 4). These woods need to also be picked and also cut in such a method as to get rid of the sapwood, the peripheral part of the trunk abundant in sugars, which attracts wood-eating pests.

What Are the Advantages of Shielding Your Wood?
Embellishes as well as Secures
Beyond maintaining the aesthetic aspect with time, utilizing a timber oil or a saturator in the protection of wood will revive its original color and also boost the grain of the timber while maintaining its natural appearance.
Maintains the Timber
Oiling a timber enables enhancing its dimensional security durably, therefore lowering the sensations of contortion (tiling, swelling, and contraction), cracking, or surface area splitting.
Natural and also Ecological
Selecting an “Oleobois” safety oil indicates picking a healthy and balanced as well as eco-friendly remedy; the make-up excludes fungicides, turpentine, and also any type of petroleum by-products regularly utilized (paraffin, white spirit, …).
Easy and Economical Upkeep
Maintenance is simple because once fueled oil; timber does not require to be removed or fined sand before renovation: a cleansing with black soap adhered to by a simple re-oiled surface area suffices. Diy Repurposed Furniture Blog
Greying of The Wood
What Is Wood Graying?
Wood is a material virtually made up of polysaccharides (cellulose and also hemicelluloses) and also lignins that will certainly be broken down under ultraviolet photons’ action. This photodegradation of the lignins, which is also highlighted in the existence of water, is in charge of the development of the shade of the wood. Greying is observed on the timber made use of outdoors without any physical defense and also UV protection. This phenomenon causes a change in the original color of the raw wood over time, which tends to come to be gray.
What Are the Consequences of Greying?
Greying or graying, which is a really shallow phenomenon, only impacts the wooden framework’s visual appeals. It does not indicate an architectural alteration as well as does not impact the strength of the material. The look of this phenomenon is limited to the surface of the timber. The loss of structural sturdiness (which can go as far as the ruin of the product) is, for its part, due to attacks of organic beginning that impact the wood in its mass.
Is it possible to avoid the greying of the wood without keeping it?
NO – Without completing products and also without upkeep, it would certainly be imaginary to declare to be able to avoid the timber from greying.
Will the application of a surface stop the timber from turning grey?
YES – If this application is made regularly, it is possible to avoid this phenomenon. The hydrophobic nature of the oil strongly restricts the timber’s affinity for water and as a result delays its activity. Diy Repurposed Furniture Blog
Corrected as well as Thermo-Oiled Timber
A number of current processes have made it feasible to boost the sturdiness and also dimensional stability of various other types substantially: these are high-temperature warm treatments (210 to 250 ° C )in a number of stages, performed in unique furnaces, either under an inert atmosphere with nitrogen (corrected timber) or with water vapor injections (Finnish heat-treated lumber). The timber tackles a beautiful brown color and also ends up being hydrophobic and also very resistant to fungal or insect attacks. However, the high temperature damages these timbers a little, which can not be utilized for structural functions (primarily in siding, parquet, and also terrace boards).
The so-called homeothermic procedure does not have this disadvantage: the timber is just heated up to 130 ° C, with an immersion in a mix based upon linseed oil and grease by-products, which allows a deep impregnation. This additionally ensures a much longer resistance to greying and also does not need regular upkeep. The procedure developers have started to market it in France: three manufacturers in the wood industry have already bought it, as well as others remain in the pipeline. The recent Wood-Protect procedure patented by Lapeyre and also INRA-INPT in Toulouse is of the exact same kind, with impregnation by autoclave and after that by saturating at 140 ° C in a mixture of grease by-products as well as acetic acid.

High-temperature treatments make the timber entirely water-proof and also fungi immune.
The wood is offered a temperature level in between 210 ° C as well as 250 ° C in unique stoves. It after that alters shade to come to be darker. The primary negative aspect is that it sheds its toughness. It can then only be used for cladding or floor covering.
Oleothermy is a therapy that includes 3 phases: home heating to 130 ° C in a rapeseed oil bath, cooling in a linseed oil bathroom, and also drying out. Because the home heating temperature is less than the previous technique, the wood is much less weak.
Research studies have revealed that homeothermic heating is valuable when done after boron treatment. Boron has anti-inflammatory buildings. The problem is that it is not resistant to cleaning. Hence, the homeothermic makes it possible to repair the particle as well as make the wood extra immune to fires, water, and shocks. For more information regarding this method, below is a doctoral thesis that was done on the topic.
Oils, Spots, as well as Paints
The sturdiness of particular species such as oak and also chestnut is mainly due to their high tannin content. These are progressively washed out by rainwater, which is a little acidic. Like various other types, oak and also chestnut, therefore, call for surface security. Linseed oil with a little turpentine included – to be made use of in heat (it penetrates far better) – is classic and also affordable protection, water-repellent, as well as hold-ups greying.
Organic timber discolorations, which are tinted however show the timber grain, give far better defense against UV rays thanks to the pigments they contain. They should 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 before renewal (a brush stroke suffices to remove the pigment dirt). When it comes to natural lacquer paints, they offer even more long lasting defense since they contain fillers (particularly chalk) that develop an entire screen versus UV rays. It’s a bit like sun creams; the protection depends upon the screen’s top quality and also the direct exposure. Diy Repurposed Furniture Blog
Surface area Security
To enhance the longevity of outside timber normally, opt for a tarnish, for instance, a blend of linseed oil and turpentine. Some commercially offered timber discolorations are tinted and also provide mild UV security. The advantage of this method is that no sanding is required.
For even far better defense, apply natural lacquer paint. It will give ideal security against ultraviolet rays– favor microporous paints having chalk fillers to allow the timber take a breath.
Securing external timber naturally can be performed with a safety stain or heat therapy. The selection of technique depends on the characteristics that you wish to change. If particular timber species can be used without security, they need to be stained after a particular duration since the safety tannins will certainly have disappeared. If you do refrain from doing this, you will have to have a professional wetness treatment.
Protecting Wood from Water
Protecting timber from water is an essential function of an outside coating before any type of attractive element. It is recommended to conserve the product with paint, varnish, stain, saturator, or oil. It is necessary to attain an actual barrier result, which must be water-proof if the timber is not to degrade too promptly.
This makes it possible to protect natural, strong, raw, or veneered wood practically over time. It is secured to keep for years in the face of the numerous climatic hostilities came across. It is durably preserved from humidity, rain, negative climate, light, sunlight, as well as ultraviolet rays, making it age prematurely. Diy Repurposed Furniture Blog
Remain Normally Permeable to Wetness
Continue to be wetness permeableStaying normally permeable to smoke is really vital. Wood is made up of plant fibers that have an exceptional fondness with water. It is, for that reason, a breakable product that continues to be conveniently permeable to water. It continues to be especially conscious different liquids that penetrate it.
Timber takes in really swiftly the humidity that exists in the ambient ambience. It absorbs water prior to normally launching it because it is a hygroscopic material. It continues to be in constant equilibrium with its atmosphere, whatever the wetness material.
These different humidity variations go to the origin of the common dimensional improvements of timber. They have the effect of triggering contortions that can often be considerable. It functions by swelling if the air is too humid. It diminishes when the atmosphere comes to be drier.
Rainfall, showers, electrical storms, as well as various other negative weather condition that touch with the wood can cause the appearance of undesirable spots, touches, leaks, and halos. Wetness, infiltration, condensation, and water vapor are also responsible for the premature aging of wood over the years. Diy Repurposed Furniture Blog
Do Not Prevent Exchanges with The Outside World.
Do not avoid exchanges with the outside not prevent communications with the outside; it has to be appreciated. When you want to protect the wood, a water-repellent item must be related to avoid water from penetrating it. It needs to be ensured that it is not impregnated by dampness if it is to last over the long term.
A timber therapy item can only be perfectly suitable if it values the various moisture exchanges. The wood should have the ability to remain to control itself with its atmosphere. It is essential to ensure that the film remains completely micro-porous to guarantee an excellent exchange efficiency.
On the other hand, impermeability and water rigidity must not be confused, which are extremely different concepts. Waterproofing has to be banned in the case of wood protection. Making a wood completely watertight may trigger the product to rot in the long-term.
Gas exchange, which regulates the moisture content in the wood’s pores, have to never ever be protected against. A wood paint must allow the substratum to breathe without ever stopping the interior evacuation to the outside. It has to just protect against water from passing through the heart of the wood, not to alter or deteriorate it.
Choosing a Right Timber Treatment Item
Choosing a timber treatment picking the appropriate wood therapy product is important to protect timber efficiently over time. There are various sorts of items that are capable of properly maintaining this product. One can use an item that penetrates deeply, such as oil, impregnation, or saturator.
A penetrating therapy offers much more reliable defense than a product that transfers a film on the surface area, such as paint, varnish, or sealer. Certainly, while a film-forming item may appear helpful originally, this is not constantly the instance in the long-term.
They can end up splitting, flaking, cracking, or peeling off over the years. Infiltration, water, or moisture passes through the product, which becomes improperly insulated. It is after that necessary to sand or strip the surface of the timber to bare it once more to be protected.
Silicones are extensively utilized in timber waterproofing products. These harmful materials must be prevented similarly as oil solvents, which are still existing in several products. They are not harmless to the user, the atmosphere, or nature. It is far better to select a bio-sourced product of plant origin that is consistent with this all-natural material.

Preserve Consistently for Adequate Security.
Maintain for good protection maintain regularly for a sufficient protection, remains an operation that must not be neglected to execute. No matter the kind of waterproofing chosen to preserve the timber, it is essential to keep it frequently to ensure that the protection stays sufficiently reliable with time.
Tedious prep work, fining sand, gritting, or removing of the surface area can be prevented using an oil, saturator, or impregnation. They have the particularity of shielding the product throughout its mass without producing a film externally that can flake off later.
A waterproofing agent’s function is to safeguard the timber from stains, marks, rings, and day-to-day deterioration. It is usually associated with an anti UV agent that will avoid the wood from ending up being too grey in the long run. It thus restricts the phenomenon of swelling or shrinking.
A non-film-forming water repellent has many advantages for maintaining a wood surface area. It is very reliable against negative climate thanks to an obstacle effect. Additionally, it stays really efficient in nourishing the wood in all its depth to the product’s actual heart. It likewise safeguards the support from light, sun, and ultraviolet rays.
