Exterior wood has 2 major adversaries: UV (ultraviolet rays from sunlight) as well as moisture. The first causes a kind of superficial melt – like on our skin, leading to little splits and also greying. Nothing dramatic, the damages is mostly aesthetic, as well as the wood is not affected comprehensive. Free Floor Plan Builder Furniture
Dampness postures a lot more extreme issues: if rainwater does not run or does not vaporize swiftly, if the wood stays in contact with the ground or if the wetness can rise by capillary action, the moisture content of the wood will certainly allow the installation of lignivorous fungi that are precursors to rot and also favor assaults by wood-eating insects. Can chemical preservative therapies be stayed clear of?
Sturdy Variety, without Sapwood
Some naturally sturdy species from our areas can be made use of without therapy when the wood is laid vertically (danger class 3) and also allows excellent water drain (cladding, home windows, shutters): in particular Douglas, larch, chestnut, oak, as well as locust. Only the last 3 varieties are recommended when the timber is laid horizontally (veranda or terrace boards) or touching the ground (threat course 4). These woods have to additionally be picked and also cut in such a means regarding eliminate the sapwood, the peripheral part of the trunk abundant in sugars, which draws in wood-eating pests.

What Are the Advantages of Securing Your Wood?
Embellishes and Secures
Beyond preserving the visual facet in time, utilizing a wood oil or a saturator in the security of timber will revitalize its initial color and also improve the grain of the wood while keeping its all-natural look.
Stabilizes the Timber
Fueling oil a wood allows enhancing its dimensional stability durably, therefore reducing the sensations of deformation (tiling, swelling, and contraction), fracturing, or surface area splitting.
Natural and Ecological
Picking an “Oleobois” protective oil indicates selecting a healthy as well as eco-friendly solution; the composition leaves out fungicides, turpentine, and any oil by-products often made use of (paraffin, white spirit, …).
Easy and also Economical Upkeep
Maintenance is very easy because once fueled oil; wood does not require to be stripped or fined sand before restoration: a cleansing with black soap adhered to by a straightforward re-oiled surface is enough. Free Floor Plan Builder Furniture
Greying of The Wood
What Is Timber Graying?
Wood is a product virtually made up of polysaccharides (cellulose as well as hemicelluloses) as well as lignins that will be deteriorated under ultraviolet photons’ action. This photodegradation of the lignins, which is also highlighted in the existence of water, is responsible for the evolution of the color of the wood. Greying is observed on the wood used outdoors without any physical defense as well as UV security. This phenomenon creates an adjustment in the initial shade of the raw wood gradually, which often tends to come to be gray.
What Are the Consequences of Greying?
Greying or graying, which is a really superficial phenomenon, just affects the wood framework’s looks. It does not indicate an architectural modification and does not affect the solidity of the material. The look of this sensation is restricted to the surface area of the wood. The loss of architectural longevity (which can reach the wreck of the product) is, for its component, due to strikes of biological origin that impact the wood in its mass.
Is it feasible to stay clear of the greying of the timber without preserving it?
NO – Without finishing products as well as without upkeep, it would be illusory to assert to be able to stop the wood from greying.
Will the application of a surface avoid the timber from turning gray?
YES – If this application is made frequently, it is feasible to prevent this sensation. The hydrophobic nature of the oil highly limits the wood’s affinity for water and also as a result delays its action. Free Floor Plan Builder Furniture
Rectified and also Thermo-Oiled Wood
Several recent procedures have actually made it possible to improve the toughness and also dimensional security of various other varieties dramatically: these are high-temperature warm treatments (210 to 250 ° C )in numerous stages, performed in unique furnaces, either under an inert environment with nitrogen (remedied timber) or with water vapor injections (Finnish heat-treated lumber). The wood handles a gorgeous brownish shade as well as comes to be hydrophobic as well as extremely immune to fungal or insect strikes. Nonetheless, the high temperature weakens these timbers a little, which can not be made use of for structural functions (primarily in siding, parquet, and balcony boards).
The so-called homeothermic process 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 vegetable oil by-products, which permits a deep impregnation. This also ensures a much longer resistance to greying as well as does not need regular maintenance. The procedure creators have started to market it in France: three manufacturers in the wood industry 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 same type, with impregnation by autoclave and after that by soaking at 140 ° C in a blend of vegetable oil derivatives and acetic acid.

High-temperature therapies make the wood wholly water-proof and also fungi immune.
The timber is offered a temperature between 210 ° C and 250 ° C in unique ovens. It after that alters shade to become darker. The primary disadvantage is that it sheds its strength. It can then only be utilized for cladding or flooring.
Oleothermy is a therapy that includes 3 phases: home heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bathroom, as well as drying out. Considering that the heating temperature level is less than the previous technique, the wood is much less fragile.
Research studies have revealed that homeothermic heating is beneficial when done after boron treatment. Boron has anti-inflammatory residential or commercial properties. The issue is that it is not resistant to washing. Hence, the homeothermic makes it feasible to repair the molecule as well as make the timber a lot more immune to fires, water, and also shocks. To find out more concerning this approach, here is a doctoral thesis that was done on the subject.
Oils, Spots, and Paints
The resilience of certain varieties such as oak as well as chestnut is mostly because of their high tannin material. Nevertheless, these are slowly rinsed by rain, which is slightly acidic. Like various other species, oak and chestnut, as a result, require surface area security. Linseed oil with a little turpentine added – to be used in hot weather (it passes through better) – is classic as well as cost-effective defense, water-repellent, as well as delays greying.
Organic timber stains, which are tinted yet show the timber grain, offer much better protection versus UV rays thanks to the pigments they contain. They need to be restored every 3 to 5 years for the south exteriors and every 8 to 10 years for the north exteriors. Unlike paints, they do not require sanding prior to renewal (a brush stroke suffices to eliminate the pigment dust). As for natural lacquer paints, they offer even more sturdy security given that they consist of fillers (specifically chalk) that develop a whole display against UV rays. It’s a little bit like sun creams; the safety and security depends on the display’s quality as well as the exposure. Free Floor Plan Builder Furniture
Surface area Protection
To improve the durability of exterior timber naturally, select a stain, as an example, a combination of linseed oil as well as turpentine. Some commercially readily available wood spots are colored as well as give minor UV protection. The benefit of this method is that no sanding is required.
For also better security, use organic lacquer paint. It will certainly offer optimum security against ultraviolet rays– prefer microporous paints including chalk fillers to let the wood take a breath.
Safeguarding outside timber naturally can be finished with a safety discolor or warm therapy. The option of approach depends on the attributes that you desire to modify. If particular timber species can be made use of without protection, they need to be stained after a particular duration due to the fact that the protective tannins will have disappeared. If you do refrain this, you will have to have an expert wetness therapy.
Safeguarding Wood from Water
Safeguarding timber from water is an important function of an exterior surface prior to any ornamental element. It is recommended to save the material with paint, varnish, tarnish, saturator, or oil. It is vital to attain a genuine barrier impact, which must be water resistant if the wood is not to weaken as well quickly.
This makes it feasible to preserve natural, strong, raw, or veneered timber practically over time. It is safeguarded to keep for many years in the face of the various weather aggressiveness encountered. It is durably maintained from moisture, rainfall, poor weather, light, sunlight, and ultraviolet rays, making it age prematurely. Free Floor Plan Builder Furniture
Continue To Be Naturally Permeable to Moisture
Continue to be moisture permeableStaying normally permeable to smoke is really essential. Timber is comprised of plant fibers that have an exceptional fondness with water. It is, consequently, a vulnerable material that stays conveniently permeable to water. It remains specifically sensitive to different fluids that penetrate it.
Wood soaks up extremely quickly the humidity that exists in the ambient ambience. It takes in water prior to normally releasing it due to the fact that it is a hygroscopic material. It continues to be in continuous equilibrium with its atmosphere, whatever the dampness web content.
These different humidity variants go to the beginning of the normal dimensional changes of wood. They have the result of creating deformations that can in some cases be considerable. It works by swelling if the air is also damp. It reduces when the atmosphere comes to be drier.
Rain, showers, electrical storms, as well as various other negative weather that touch with the wood can trigger the appearance of unattractive discolorations, touches, trickles, as well as halos. Moisture, infiltration, condensation, as well as water vapor are likewise in charge of the early aging of wood for many years. Free Floor Plan Builder Furniture
Do Not Stop Exchanges with The Outdoors.
Do not stop exchanges with the outside not protect against interactions with the exterior; it needs to be valued. When you want to safeguard the wood, a water-repellent item must be applied to avoid water from permeating it. It must be guaranteed that it is not impregnated by moisture if it is to last over the long-term.
A wood therapy item can only be perfectly suitable if it respects the various moisture exchanges. The timber needs to be able to remain to regulate itself with its environment. It is essential to make certain that the film continues to be completely micro-porous to guarantee an excellent exchange performance.
On the other hand, impermeability and also water tightness ought to not be puzzled, which are extremely various concepts. Waterproofing should be banned when it comes to timber protection. Making a wood completely watertight might create the product to rot in the long term.
Gas exchange, which regulates the moisture content in the wood’s pores, need to never be stopped. A wood paint need to allow the substratum to take a breath without ever stopping the inner emptying to the exterior. It needs to just protect against water from passing through the heart of the wood, not to alter or weaken it.
Picking a Right Wood Treatment Item
Picking a wood treatment selecting the right timber treatment product is necessary to protect timber effectively in time. There are various kinds of items that are capable of properly preserving this product. One can utilize a product that penetrates deeply, such as oil, impregnation, or saturator.
A permeating treatment gives extra efficient protection than a product that deposits a movie on the surface area, such as paint, varnish, or sealant. Indeed, while a film-forming product might seem useful originally, this is not constantly the case in the long-term.
They can end up splitting, flaking, cracking, or peeling off over the years. Infiltration, water, or moisture penetrates the product, which comes to be improperly insulated. It is after that vital to sand or strip the surface area of the wood to bare it once again to be maintained.
Silicones are widely used in timber waterproofing products. These hazardous substances should be stayed clear of similarly as petroleum solvents, which are still present in lots of products. They are not safe to the customer, the atmosphere, or nature. It is better to choose a bio-sourced item of plant beginning that is consistent with this natural product.

Keep Regularly for Adequate Protection.
Preserve forever security keep regularly for an adequate defense, continues to be an operation that needs to not be neglected to do. No matter the sort of waterproofing selected to preserve the wood, it is needed to maintain it on a regular basis to ensure that the protection remains adequately reliable gradually.
Laborious 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 protecting the material throughout its mass without producing a film externally that can exfoliate later.
A waterproofing representative’s feature is to shield the wood from stains, marks, rings, and everyday deterioration. It is typically related to an anti UV representative that will prevent the wood from becoming too grey over time. It thus limits the phenomenon of swelling or shrinkage.
A non-film-forming water repellent has lots of advantages for preserving a wooden surface. It is really efficient against negative weather thanks to an obstacle effect. Also, it remains extremely reliable in nourishing the timber in all its deepness to the product’s very heart. It also protects the support from light, sun, as well as ultraviolet rays.
