Outside wood has 2 main enemies: UV (ultraviolet rays from sunlight) and humidity. The first causes a sort of superficial burn – like on our skin, resulting in little splits and also greying. Absolutely nothing dramatic, the damages is generally visual, and the timber is not affected in depth. Free Furniture Plan Drawing Software
Dampness positions a lot more extreme troubles: if rain does not run off or does not vaporize rapidly, if the wood remains in contact with the ground or if the wetness can climb by capillary activity, the moisture content of the wood will allow the setup of lignivorous fungis that are forerunners to rot and favor attacks by wood-eating insects. Can chemical preservative therapies be stayed clear of?
Durable Variety, without Sapwood
Some naturally resilient varieties from our areas can be made use of without treatment when the timber is laid up and down (threat class 3) and permits great water drain (cladding, home windows, shutters): specifically Douglas, larch, chestnut, oak, as well as locust. Just the last 3 species are suggested when the timber is laid flat (porch or terrace boards) or in contact with the ground (threat class 4). These timbers must likewise be picked and cut in such a method regarding remove the sapwood, the outer part of the trunk rich in sugars, which attracts wood-eating pests.

What Are the Benefits of Safeguarding Your Timber?
Embellishes and also Protects
Past preserving the visual aspect with time, utilizing a wood oil or a saturator in the security of wood will certainly revitalize its initial color and also improve the grain of the timber while keeping its natural appearance.
Stabilizes the Timber
Fueling oil a wood enables improving its dimensional security durably, thus reducing the sensations of deformation (tiling, swelling, as well as shrinking), breaking, or surface splitting.
All-natural as well as Ecological
Picking an “Oleobois” safety oil indicates picking a healthy and balanced as well as environmentally friendly service; the composition excludes fungicides, turpentine, as well as any kind of petroleum by-products often used (paraffin, white spirit, …).
Easy as well as Economical Upkeep
Upkeep is very easy since once oiled; timber does not need to be removed or fined sand before improvement: a cleaning with black soap complied with by a simple re-oiled surface area is enough. Free Furniture Plan Drawing Software
Greying of The Timber
What Is Wood Graying?
Timber is a material almost made up of polysaccharides (cellulose and also hemicelluloses) as well as lignins that will certainly be broken down 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 wood made use of outdoors with no physical security as well as UV defense. This phenomenon causes an adjustment in the original shade of the raw timber gradually, which often tends to end up being grey.
What Are the Repercussions of Greying?
Greying or graying, which is a really superficial phenomenon, only influences the wood structure’s aesthetics. It does not show an architectural change as well as does not affect the solidity of the product. The look of this sensation is limited to the surface of the timber. The loss of structural resilience (which can go as far as the mess up of the product) is, for its component, as a result of strikes of biological origin that influence the timber in its mass.
Is it possible to prevent the greying of the timber without preserving it?
NO – Without completing products as well as without upkeep, it would be imaginary to declare to be able to stop the timber from greying.
Will the application of a finish stop the wood from transforming grey?
YES – If this application is made routinely, it is feasible to prevent this sensation. The hydrophobic nature of the oil highly restricts the timber’s affinity for water and consequently postpones its activity. Free Furniture Plan Drawing Software
Fixed as well as Thermo-Oiled Timber
Several current procedures have actually made it possible to improve the toughness and also dimensional stability of other types considerably: these are high-temperature heat therapies (210 to 250 ° C )in several stages, executed in special furnaces, either under an inert ambience with nitrogen (fixed wood) or with water vapor shots (Finnish heat-treated lumber). The timber tackles a beautiful brownish shade and also becomes hydrophobic as well as very immune to fungal or insect attacks. The high temperature compromises these timbers a little, which can not be utilized for architectural purposes (generally in home siding, parquet, as well as balcony boards).
The so-called homeothermic procedure does not have this downside: the timber is only heated up to 130 ° C, with an immersion in a blend based on linseed oil as well as vegetable oil by-products, which enables a deep impregnation. This likewise guarantees a longer resistance to greying and also does not call for routine maintenance. The process designers have actually started to market it in France: 3 producers in the wood market have actually currently bought it, as well as others remain in the pipe. The recent Wood-Protect procedure patented by Lapeyre and INRA-INPT in Toulouse is of the same kind, with impregnation by autoclave and afterwards by saturating at 140 ° C in a mixture of vegetable oil by-products and acetic acid.

High-temperature treatments make the timber wholly water-proof and fungus immune.
The wood is brought to a temperature between 210 ° C and also 250 ° C in unique stoves. It then transforms color to come to be darker. The primary drawback is that it loses its toughness. It can then only be made use of for cladding or flooring.
Oleothermy is a treatment that contains 3 stages: home heating to 130 ° C in a rapeseed oil bathroom, cooling down in a linseed oil bath, and also drying. Considering that the heating temperature level is less than the previous technique, the timber is much less fragile.
Studies have shown that homeothermic home heating is helpful when done after boron therapy. Boron has anti-inflammatory residential or commercial properties. The trouble is that it is not resistant to cleaning. Thus, the homeothermic makes it possible to repair the molecule as well as make the timber more immune to flames, water, and also shocks. To find out more concerning this technique, below is a doctoral thesis that was done on the subject.
Oils, Spots, as well as Paints
The toughness of particular species such as oak and also chestnut is mostly because of their high tannin content. Nevertheless, these are gradually washed out by rainwater, which is a little acidic. Like various other types, oak and also chestnut, for that reason, need surface protection. Linseed oil with a little turpentine included – to be made use of in hot weather (it penetrates better) – is traditional and also affordable defense, water-repellent, as well as delays greying.
Organic wood discolorations, which are colored yet show the wood grain, give better security against UV rays thanks to the pigments they consist of. However, they should be restored every 3 to 5 years for the south exteriors as well as every 8 to ten years for the north exteriors. Unlike paints, they do not need sanding before revival (a brush stroke is enough to eliminate the pigment dust). When it comes to organic lacquer paints, they give more durable defense considering that they have fillers (particularly chalk) that create a whole screen against UV rays. It’s a little bit like sun creams; the protection depends on the screen’s high quality and also the direct exposure. Free Furniture Plan Drawing Software
Surface area Security
To improve the durability of outdoor wood normally, opt for a stain, as an example, a combination of linseed oil as well as turpentine. Some readily readily available wood spots are colored as well as supply mild UV security. The advantage of this technique is that no sanding is called for.
For also much better security, use natural lacquer paint. It will certainly offer optimal security versus ultraviolet rays– prefer microporous paints containing chalk fillers to let the wood breathe.
Securing outside wood normally can be performed with a protective discolor or heat therapy. The choice of technique depends on the qualities that you wish to modify. If particular timber varieties can be utilized without security, they need to be discolored after a specific duration due to the fact that the protective tannins will certainly have vanished. If you do not do this, you will certainly have to have an expert moisture treatment.
Securing Timber from Water
Safeguarding wood from water is an important feature of an outside finish prior to any attractive element. It is recommended to conserve the material with paint, varnish, tarnish, saturator, or oil. Undoubtedly, it is important to attain a genuine obstacle effect, which have to be waterproof if the wood is not to wear away too promptly.
This makes it possible to preserve natural, strong, raw, or veneered wood basically in time. It is protected to maintain for years despite the different weather hostilities came across. It is durably maintained from humidity, rainfall, poor weather condition, light, sun, as well as ultraviolet rays, making it age prematurely. Free Furniture Plan Drawing Software
Remain Naturally Absorptive to Dampness
Continue to be wetness permeableStaying normally permeable to smoke is really important. Wood is composed of plant fibers that have an exceptional affinity with water. It is, therefore, a vulnerable material that remains easily permeable to water. It remains especially sensitive to numerous liquids that permeate it.
Wood takes in really swiftly the humidity that exists in the ambient environment. It absorbs water before normally releasing it due to the fact that it is a hygroscopic product. It remains in continuous balance with its atmosphere, whatever the moisture material.
These different humidity variations go to the origin of the normal dimensional improvements of timber. They have the effect of triggering deformations that can in some cases be considerable. It functions by swelling if the air is also moist. It diminishes when the ambience comes to be drier.
Rain, showers, electrical storms, and also various other poor weather condition that touch with the timber can trigger the appearance of undesirable stains, touches, drips, as well as halos. Dampness, infiltration, condensation, and also water vapor are also responsible for the early aging of timber for many years. Free Furniture Plan Drawing Software
Do Not Stop Exchanges with The Outside World.
Do not protect against exchanges with the outdoors not avoid communications with the exterior; it has to be appreciated. When you want to secure the timber, a water-repellent product needs to be put on stay clear of water from penetrating it. It needs to be guaranteed that it is not impregnated by dampness if it is to last over the long term.
A wood treatment item can just be flawlessly appropriate if it values the different dampness exchanges. The wood should have the ability to remain to manage itself with its atmosphere. It is important to make sure that the movie remains adequately micro-porous to guarantee a great exchange effectiveness.
On the other hand, impermeability as well as water tightness should not be puzzled, which are very different notions. Waterproofing needs to be forbidden in the case of timber security. Making a timber totally watertight might trigger the material to rot in the long-term.
Gas exchange, which regulates the wetness content in the timber’s pores, need to never be protected against. A wood paint need to enable the substratum to take a breath without ever quiting the internal emptying to the exterior. It has to just avoid water from penetrating the heart of the wood, not to change or deteriorate it.
Picking a Right Timber Treatment Item
Selecting a timber therapy selecting the appropriate timber treatment product is essential to shield timber successfully with time. There are various sorts of items that are capable of successfully maintaining this product. One can use a product that passes through deeply, such as oil, impregnation, or saturator.
A permeating treatment supplies extra reliable security than an item that transfers a film on the surface, such as paint, varnish, or sealer. While a film-forming item might appear beneficial originally, this is not constantly the case in the lengthy term.
Without a doubt, they can wind up breaking, flaking, fracturing, or peeling over the years. Infiltration, water, or moisture permeates the product, which becomes badly insulated. It is then vital to sand or strip the surface area of the wood to bare it once again to be maintained.
Silicones are commonly utilized in wood waterproofing products. These unsafe materials should be stayed clear of in the same way as petroleum solvents, which are still present in numerous items. They are not harmless to the customer, the atmosphere, or nature. It is far better to pick a bio-sourced item of plant origin that is consistent with this natural product.

Keep Routinely for Adequate Defense.
Keep permanently protection preserve regularly for a sufficient defense, continues to be a procedure that must not be forgotten to execute. Despite the type of waterproofing selected to preserve the wood, it is needed to keep it routinely to ensure that the defense continues to be adequately effective over time.
Tiresome preparation, fining sand, gritting, or stripping of the surface can be avoided making use of 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 shield the timber from spots, marks, rings, and everyday deterioration. It is generally associated with an anti UV agent that will certainly stop the wood from becoming as well grey in the long run. It hence restricts the phenomenon of swelling or shrinkage.
A non-film-forming water repellent has several benefits for preserving a wood surface. It is very effective against bad climate thanks to an obstacle effect. Likewise, it continues to be really efficient in nourishing the timber in all its depth to the material’s very heart. It likewise safeguards the assistance from light, sunlight, and ultraviolet rays.
