Outside timber has 2 primary opponents: UV (ultraviolet rays from sunshine) and moisture. The first causes a kind of superficial burn – like on our skin, causing small cracks and greying. Absolutely nothing remarkable, the damages is primarily aesthetic, and the timber is not impacted in depth. Open Plan Furniture Layout
Dampness postures a lot more serious issues: if rain does not escape or does not evaporate promptly, if the timber continues to be in contact with the ground or if the dampness can climb by capillary activity, the wetness web content of the wood will permit the installation of lignivorous fungis that are precursors to rot and also favor assaults by wood-eating insects. Can chemical preservative treatments be prevented?
Long lasting Variety, without Sapwood
Some naturally long lasting species from our areas can be used without treatment when the timber is laid vertically (risk course 3) and enables excellent water drain (cladding, home windows, shutters): particularly Douglas, larch, chestnut, oak, as well as locust. Only the last 3 varieties are advised when the wood is laid horizontally (veranda or terrace boards) or in contact with the ground (danger class 4). These timbers need to likewise be picked and also cut in such a means regarding get rid of the sapwood, the outer part of the trunk rich in sugars, which brings in wood-eating bugs.

What Are the Benefits of Safeguarding Your Wood?
Embellishes as well as Protects
Past keeping the aesthetic element gradually, utilizing a timber oil or a saturator in the protection of wood will revitalize its original shade and also improve the grain of the timber while keeping its natural appearance.
Stabilizes the Wood
Fueling oil a timber permits boosting its dimensional security durably, therefore reducing the phenomena of contortion (tiling, swelling, and contraction), fracturing, or surface splitting.
Natural and Ecological
Choosing an “Oleobois” safety oil suggests choosing a healthy as well as environmentally friendly remedy; the structure excludes fungicides, turpentine, and any type of petroleum derivatives regularly used (paraffin, white spirit, …).
Easy and also Economical Maintenance
Maintenance is easy since when oiled; wood does not require to be removed or fined sand before restoration: a cleansing with black soap complied with by an easy re-oiled surface suffices. Open Plan Furniture Layout
Greying of The Wood
What Is Wood Graying?
Wood is a product nearly composed of polysaccharides (cellulose as well as hemicelluloses) and lignins that will be weakened under ultraviolet photons’ action. This photodegradation of the lignins, which is additionally accentuated in the presence of water, is responsible for the evolution of the color of the wood. Greying is observed on the timber utilized outdoors without any physical defense and UV protection. This phenomenon triggers a modification in the initial color of the raw wood in time, which often tends to end up being grey.
What Are the Consequences of Greying?
Greying or graying, which is a really shallow sensation, only impacts the wooden framework’s visual appeals. It does not suggest an architectural modification and does not influence the strength of the product. The appearance of this sensation is restricted to the surface area of the wood. The loss of structural toughness (which can reach the destroy of the material) is, for its part, as a result of attacks of organic beginning that affect the timber in its mass.
Is it possible to prevent the greying of the wood without keeping it?
NO – Without ending up items as well as without maintenance, it would certainly be imaginary to assert to be able to stop the timber from greying.
Will the application of a surface prevent the timber from transforming grey?
YES – If this application is made routinely, it is feasible to avoid this sensation. The hydrophobic nature of the oil highly restricts the timber’s affinity for water and also for that reason delays its action. Open Plan Furniture Layout
Fixed and Thermo-Oiled Timber
Numerous current procedures have made it feasible to enhance the resilience and dimensional stability of other varieties substantially: these are high-temperature warm therapies (210 to 250 ° C )in several stages, performed in special heating systems, either under an inert environment with nitrogen (remedied wood) or with water vapor shots (Finnish heat-treated lumber). The wood tackles a lovely brown shade and also becomes hydrophobic as well as very resistant to fungal or insect strikes. Nonetheless, the heat deteriorates these timbers a little, which can not be made use of for structural functions (primarily in house siding, parquet, and terrace boards).
The so-called homeothermic procedure does not have this downside: the timber is just heated up to 130 ° C, with an immersion in a mix based on linseed oil as well as vegetable oil by-products, which permits a deep impregnation. This additionally guarantees a longer resistance to greying and does not need routine maintenance. The procedure designers have started to market it in France: three producers in the timber sector have currently bought it, and also others remain in the pipe. The current Wood-Protect procedure patented by Lapeyre and also INRA-INPT in Toulouse is of the same type, with impregnation by autoclave and afterwards by soaking at 140 ° C in a combination of vegetable oil by-products and acetic acid.

High-temperature therapies make the timber wholly waterproof and also fungi immune.
The timber is given a temperature level between 210 ° C as well as 250 ° C in unique stoves. It then transforms color to become darker. The main drawback is that it loses its toughness. It can after that just be utilized for cladding or flooring.
Oleothermy is a therapy that consists of 3 phases: home heating to 130 ° C in a rapeseed oil bath, cooling in a linseed oil bath, and drying. Since the heating temperature is less than the previous technique, the timber is much less brittle.
Studies have shown that homeothermic home heating is useful when done after boron therapy. Boron has anti-inflammatory residential properties. The issue is that it is not immune to washing. Thus, the homeothermic makes it feasible to deal with the particle as well as make the timber much more resistant to fires, water, and shocks. To read more concerning this approach, right here is a doctoral thesis that was done on the topic.
Oils, Stains, as well as Paints
The durability of certain varieties such as oak and also chestnut is mostly because of their high tannin web content. These are gradually cleaned out by rain, which is slightly acidic. Like other species, oak and also chestnut, therefore, require surface area protection. Linseed oil with a little turpentine added – to be used in hot weather (it permeates better) – is classic and also inexpensive defense, water-repellent, as well as hold-ups greying.
Organic wood spots, which are colored but reveal the wood grain, supply better protection against UV rays thanks to the pigments they have. Nonetheless, they need to be renewed every 3 to 5 years for the south exteriors as well as every 8 to 10 years for the north facades. Unlike paints, they do not call for sanding before renewal (a brush stroke suffices to remove the pigment dirt). As for organic lacquer paints, they provide more resilient security since they contain fillers (particularly chalk) that form a whole screen against UV rays. It’s a bit like sun creams; the security relies on the display’s high quality and also the exposure. Open Plan Furniture Layout
Surface area Defense
To improve the toughness of outdoor timber normally, opt for a stain, for instance, a blend of linseed oil as well as turpentine. Some readily readily available wood discolorations are tinted as well as supply minor UV protection. The advantage of this approach is that no sanding is required.
For even much better protection, use organic lacquer paint. It will certainly offer optimum protection versus ultraviolet rays– prefer microporous paints consisting of chalk fillers to let the timber breathe.
Safeguarding exterior timber normally can be made with a safety tarnish or warm therapy. The selection of method relies on the characteristics that you want to modify. If certain timber varieties can be made use of without protection, they need to be stained after a particular period because the protective tannins will have disappeared. If you do refrain from doing this, you will certainly have to have a specialist dampness therapy.
Safeguarding Wood from Water
Safeguarding wood from water is an important feature of an outside surface before any type of decorative aspect. It is recommended to save the material with paint, varnish, tarnish, saturator, or oil. Without a doubt, it is vital to achieve a real obstacle effect, which must be water-proof if the wood is not to deteriorate also swiftly.
This makes it feasible to protect natural, strong, raw, or veneered wood practically over time. It is shielded to maintain for several years when faced with the different weather aggressions encountered. It is durably preserved from humidity, rain, poor weather, light, sun, and ultraviolet rays, making it age too soon. Open Plan Furniture Layout
Stay Normally Permeable to Moisture
Continue to be dampness permeableStaying normally permeable to smoke is very crucial. Wood is made up of plant fibers that have a superb fondness with water. It is, therefore, a fragile material that remains conveniently absorptive to water. It continues to be particularly conscious different liquids that permeate it.
Timber soaks up very swiftly the humidity that is present in the ambient ambience. It absorbs water prior to normally launching it since it is a hygroscopic product. It stays in consistent equilibrium with its atmosphere, whatever the wetness content.
These different humidity variations are at the origin of the typical dimensional improvements of wood. They have the effect of triggering contortions that can often be substantial. It works by swelling if the air is too damp. It shrinks when the ambience comes to be drier.
Rain, showers, thunderstorms, as well as other negative climate that are in contact with the wood can cause the appearance of unpleasant discolorations, streaks, drips, and halos. Moisture, infiltration, condensation, and also water vapor are additionally in charge of the early aging of timber over the years. Open Plan Furniture Layout
Do Not Stop Exchanges with The Outside World.
Do not protect against exchanges with the outdoors not stop communications with the outside; it should be appreciated. When you wish to protect the wood, a water-repellent product should be put on stay clear of water from penetrating it. It must be ensured that it is not fertilized by moisture if it is to last over the long-term.
A wood treatment item can only be flawlessly suitable if it values the various moisture exchanges. The timber must have the ability to continue to manage itself with its atmosphere. It is important to guarantee that the movie stays adequately micro-porous to assure an excellent exchange performance.
On the other hand, impermeability and also water rigidity must not be confused, which are very various notions. Waterproofing needs to be banned in the case of timber security. Making a wood totally watertight may trigger the material to rot in the long term.
Gas exchange, which manages the wetness material in the timber’s pores, must never ever be avoided. A timber paint should enable the substrate to breathe without ever quiting the inner evacuation to the outside. It should just prevent water from permeating the heart of the timber, not to change or degrade it.
Selecting a Right Timber Treatment Item
Selecting a wood treatment choosing the ideal timber treatment product is essential to secure wood successfully gradually. There are different kinds of products that can effectively maintaining this product. One can utilize a product that penetrates deeply, such as oil, impregnation, or saturator.
A passing through treatment provides more effective defense than a product that transfers a film on the surface, such as paint, varnish, or sealer. Without a doubt, while a film-forming product might seem useful originally, this is not always the instance in the long term.
Indeed, they can end up breaking, flaking, splitting, or removing throughout the years. Seepage, water, or humidity penetrates the product, which ends up being improperly shielded. It is after that essential to sand or strip the surface area of the timber to bare it once again to be preserved.
Silicones are widely used in wood waterproofing items. These damaging materials must be prevented similarly as oil solvents, which are still existing in lots of items. They are not harmless to the customer, the environment, or nature. It is far better to select a bio-sourced product of plant beginning that follows this all-natural material.

Keep Consistently for Adequate Protection.
Keep forever protection keep regularly for an appropriate defense, continues to be a procedure that ought to not be forgotten to execute. Despite the kind of waterproofing picked to protect the timber, it is needed to preserve it regularly to ensure that the defense stays sufficiently efficient over time.
Tedious prep work, fining sand, gritting, or removing of the surface can be prevented using an oil, saturator, or impregnation. They have the particularity of securing the material throughout its mass without producing a film on the surface that can flake off afterward.
A waterproofing agent’s function is to shield the timber from spots, marks, rings, and also everyday deterioration. It is generally related to an anti UV agent that will protect against the timber from ending up being also grey in the long run. It therefore limits the sensation of swelling or contraction.
A non-film-forming water repellent has lots of benefits for preserving a wooden surface. It is very effective versus bad weather condition thanks to an obstacle result. Additionally, it remains really effective in nurturing the timber in all its deepness to the product’s very heart. It also protects the assistance from light, sun, and ultraviolet rays.
