Outdoor timber has 2 primary enemies: UV (ultraviolet rays from sunshine) and also humidity. The first causes a sort of shallow shed – like on our skin, causing small fractures as well as greying. Nothing significant, the damage is primarily visual, and the timber is not impacted in depth. Kitchen Furniture In Plan
Wetness postures much more serious issues: if rain does not run or does not evaporate rapidly, if the timber stays touching the ground or if the wetness can climb by capillary activity, the wetness material of the timber will permit the installation of lignivorous fungi that are precursors to rot and also favor attacks by wood-eating bugs. Can chemical preservative therapies be stayed clear of?
Sturdy Variety, without Sapwood
Some naturally long lasting varieties from our areas can be made use of without therapy when the wood is laid up and down (danger course 3) as well as permits good water drainage (cladding, windows, shutters): particularly Douglas, larch, chestnut, oak, and grasshopper. Just the last three species are advised when the wood is laid horizontally (porch or balcony boards) or touching the ground (danger class 4). These woods have to likewise be picked as well as cut in such a method regarding get rid of the sapwood, the peripheral part of the trunk abundant in sugars, which draws in wood-eating pests.

What Are the Benefits of Shielding Your Timber?
Embellishes and Safeguards
Beyond keeping the visual aspect over time, making use of a timber oil or a saturator in the security of timber will certainly revive its initial shade and also enhance the grain of the timber while maintaining its natural appearance.
Maintains the Timber
Fueling oil a wood enables improving its dimensional security durably, therefore decreasing the sensations of contortion (tiling, swelling, as well as shrinkage), fracturing, or surface area splitting.
All-natural and Ecological
Choosing an “Oleobois” protective oil implies picking a healthy and balanced and also environmentally friendly remedy; the composition leaves out fungicides, turpentine, and also any oil derivatives often utilized (paraffin, white spirit, …).
Easy and also Economical Upkeep
Upkeep is simple because as soon as oiled; timber does not require to be removed or fined sand prior to improvement: a cleaning with black soap adhered to by a straightforward re-oiled surface area is enough. Kitchen Furniture In Plan
Greying of The Timber
What Is Wood Graying?
Timber is a material virtually comprised of polysaccharides (cellulose and hemicelluloses) and lignins that will certainly be weakened under ultraviolet photons’ activity. This photodegradation of the lignins, which is also emphasized in the existence of water, is accountable for the evolution of the color of the timber. Greying is observed on the hardwood utilized outdoors with no physical defense and UV defense. This sensation triggers a modification in the original shade of the raw timber gradually, which tends to end up being gray.
What Are the Repercussions of Greying?
Greying or graying, which is a very surface phenomenon, just impacts the wooden structure’s aesthetic appeals. It does not show an architectural modification and also does not affect the strength of the material. The appearance of this sensation is limited to the surface area of the wood. The loss of architectural durability (which can go as far as the ruin of the product) is, for its part, as a result of assaults of biological beginning that affect the wood in its mass.
Is it feasible to avoid the greying of the timber without maintaining it?
NO – Without ending up items and without maintenance, it would certainly be imaginary to claim to be able to avoid the wood from greying.
Will the application of a surface stop the wood from transforming gray?
YES – If this application is made routinely, it is feasible to avoid this sensation. The hydrophobic nature of the oil strongly limits the wood’s affinity for water and also as a result postpones its activity. Kitchen Furniture In Plan
Corrected and Thermo-Oiled Wood
A number of recent processes have made it possible to enhance the toughness and dimensional stability of various other varieties substantially: these are high-temperature warm treatments (210 to 250 ° C )in several stages, accomplished in unique furnaces, either under an inert ambience with nitrogen (fixed wood) or with water vapor injections (Finnish heat-treated lumber). The wood tackles an attractive brownish shade and also comes to be hydrophobic and also extremely immune to fungal or insect attacks. Nonetheless, the high temperature deteriorates these woods a little, which can not be made use of for architectural objectives (primarily in home siding, parquet, and balcony boards).
The so-called homeothermic process does not have this negative aspect: the timber is just warmed up to 130 ° C, with an immersion in a mix based on linseed oil and vegetable oil derivatives, which permits a deep impregnation. This also guarantees a much longer resistance to greying as well as does not need regular maintenance. The procedure designers have started to market it in France: three suppliers in the timber market have currently bought it, as well as others remain in the pipeline. The recent Wood-Protect process patented by Lapeyre as well as INRA-INPT in Toulouse is of the very same type, with impregnation by autoclave and then by soaking at 140 ° C in a combination of grease by-products and acetic acid.

High-temperature therapies make the timber completely water-proof and fungi resistant.
The wood is offered a temperature between 210 ° C and 250 ° C in special stoves. It after that changes shade to end up being darker. The main negative aspect is that it sheds its strength. It can then just be made use of for cladding or floor covering.
Oleothermy is a treatment that includes 3 stages: heating to 130 ° C in a rapeseed oil bath, cooling down in a linseed oil bath, and drying. Because the heating temperature is lower than the previous method, the timber is much less weak.
Research studies have actually shown that homeothermic home heating is valuable when done after boron treatment. Boron has anti-inflammatory buildings. The problem is that it is not immune to washing. Hence, the homeothermic makes it feasible to fix the molecule and make the wood much more resistant to fires, water, and shocks. To find out more regarding this approach, here is a doctoral thesis that was done on the topic.
Oils, Spots, and also Paints
The toughness of certain varieties such as oak and also chestnut is generally as a result of their high tannin material. These are progressively washed out by rainwater, which is somewhat acidic. Like various other types, oak and also chestnut, as a result, require surface defense. Linseed oil with a little turpentine added – to be made use of in hot weather (it penetrates far better) – is timeless and economical defense, water-repellent, and also delays greying.
Organic timber spots, which are tinted however show the wood grain, supply better defense versus UV rays thanks to the pigments they consist of. 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 before renewal (a brush stroke suffices to get rid of the pigment dirt). As for natural lacquer paints, they give even more sturdy defense because they have fillers (specifically chalk) that create an entire screen versus UV rays. It’s a bit like sun creams; the protection depends on the screen’s high quality and also the exposure. Kitchen Furniture In Plan
Surface area Defense
To boost the toughness of exterior wood naturally, go with a discolor, as an example, a combination of linseed oil and turpentine. Some commercially available wood stains are tinted as well as give mild UV protection. The advantage of this method is that no sanding is needed.
For even better protection, use natural lacquer paint. It will certainly offer ideal protection versus ultraviolet rays– favor microporous paints containing chalk fillers to let the timber take a breath.
Securing external wood normally can be finished with a safety tarnish or heat treatment. The choice of approach relies on the attributes that you wish to customize. If certain wood varieties can be used without security, they must be discolored after a certain period because the protective tannins will have disappeared. If you do refrain this, you will certainly need to have a specialist moisture treatment.
Protecting Wood from Water
Protecting wood from water is a vital function of an outside surface before any type of ornamental facet. It is advised to save the product with paint, varnish, tarnish, saturator, or oil. Without a doubt, it is vital to achieve a real obstacle impact, which need to be water-proof if the timber is not to degrade too quickly.
This makes it possible to maintain natural, strong, raw, or veneered wood practically gradually. It is secured to maintain for many years despite the various weather hostilities ran into. It is durably preserved from humidity, rain, negative weather, light, sun, and ultraviolet rays, making it age too soon. Kitchen Furniture In Plan
Remain Normally Absorptive to Wetness
Stay moisture permeableStaying normally permeable to smoke is extremely important. Wood is comprised of plant fibers that have an excellent affinity with water. It is, for that reason, a fragile material that continues to be quickly absorptive to water. It continues to be especially sensitive to numerous fluids that penetrate it.
Wood takes in very swiftly the humidity that exists in the ambient atmosphere. It soaks up water prior to normally releasing it due to the fact that it is a hygroscopic material. It remains in constant equilibrium with its atmosphere, whatever the moisture web content.
These different humidity variations are at the origin of the normal dimensional changes of timber. They have the impact of triggering contortions that can sometimes be substantial. It works by swelling if the air is too moist. It shrinks when the atmosphere comes to be drier.
Rainfall, showers, thunderstorms, and other poor climate that are in contact with the wood can create the appearance of unsightly stains, touches, trickles, as well as halos. Moisture, infiltration, condensation, and also water vapor are also responsible for the premature aging of timber over the years. Kitchen Furniture In Plan
Do Not Avoid Exchanges with The Outside World.
Do not avoid exchanges with the outside not avoid interactions with the outside; it needs to be respected. When you wish to safeguard the timber, a water-repellent product should be related to prevent water from penetrating it. It must be made sure that it is not fertilized by wetness if it is to last over the long term.
A timber treatment product can only be flawlessly appropriate if it appreciates the different moisture exchanges. The timber needs to be able to remain to control itself with its environment. It is essential to ensure that the movie remains completely micro-porous to guarantee a great exchange performance.
On the other hand, impermeability and also water rigidity should not be puzzled, which are really different concepts. Waterproofing has to be banned when it comes to timber protection. Making a timber totally watertight might cause the product to rot in the long term.
Gas exchange, which manages the moisture content in the wood’s pores, must never be avoided. A wood paint should enable the substratum to take a breath without ever before stopping the inner discharge to the outside. It must simply stop water from penetrating the heart of the timber, not to alter or deteriorate it.
Selecting a Right Wood Treatment Item
Choosing a wood therapy selecting the ideal wood therapy product is important to secure wood effectively over time. There are various sorts of products that are capable of properly maintaining this material. One can use a product that penetrates deeply, such as oil, impregnation, or saturator.
A penetrating treatment supplies more reliable protection than a product that transfers a film on the surface, such as paint, varnish, or sealer, for instance. While a film-forming item might appear valuable at first, this is not constantly the case in the lengthy term.
They can finish up splitting, flaking, fracturing, or peeling off over the years. Seepage, water, or humidity passes through the material, which ends up being poorly shielded. It is after that essential to sand or strip the surface of the wood to bare it once more to be maintained.
Silicones are commonly made use of in timber waterproofing products. These hazardous compounds must be stayed clear of similarly as petroleum solvents, which are still existing in numerous items. They are not safe to the user, the environment, or nature. It is much better to choose a bio-sourced item of plant beginning that follows this natural product. Kitchen Furniture In Plan
Preserve Routinely for Adequate Protection.
Preserve for good protection maintain consistently for a sufficient defense, continues to be an operation that ought to not be neglected to do. No matter the type of waterproofing selected to protect the timber, it is necessary to preserve it routinely to make sure that the security remains completely reliable in time.
Tiresome prep work, fining sand, gritting, or stripping of the surface area can be stayed clear of using an oil, saturator, or impregnation. They have the particularity of securing the product throughout its mass without developing a film externally that can exfoliate afterward.
A waterproofing agent’s feature is to protect the timber from discolorations, marks, rings, and also day-to-day damage. It is typically associated with an anti UV representative that will protect against the timber from becoming too grey in the future. It therefore limits the phenomenon of swelling or contraction.
A non-film-forming water repellent has numerous advantages for maintaining a wood surface area. It is very efficient versus bad climate thanks to an obstacle impact. It continues to be really reliable in nurturing the wood in all its deepness to the material’s actual heart. It additionally shields the assistance from light, sunlight, and also ultraviolet rays.
