Exterior wood has 2 main enemies: UV (ultraviolet rays from sunshine) and also moisture. The first causes a kind of superficial melt – like on our skin, leading to tiny cracks and also greying. Nothing remarkable, the damage is primarily aesthetic, as well as the timber is not affected in depth. Diy Pottery Barn Diy Furniture
Moisture presents a lot more extreme issues: if rain does not escape or does not evaporate promptly, if the wood stays touching the ground or if the moisture can rise by capillary action, the moisture material of the timber will certainly permit the setup of lignivorous fungi that are forerunners to rot and also support assaults by wood-eating bugs. Can chemical preservative treatments be avoided?
Durable Types, without Sapwood
Some naturally sturdy species from our regions can be made use of without treatment when the timber is laid up and down (threat class 3) as well as enables great water drainage (cladding, windows, shutters): particularly Douglas, larch, chestnut, oak, as well as locust. Just the last 3 species are advised when the wood is laid flat (veranda or balcony boards) or touching the ground (danger course 4). These woods should likewise be selected as well as cut in such a method as to get rid of the sapwood, the outer part of the trunk abundant in sugars, which attracts wood-eating bugs.

What Are the Benefits of Securing Your Wood?
Embellishes and Secures
Past keeping the visual element in time, utilizing a wood oil or a saturator in the security of timber will revive its initial shade and also boost the grain of the wood while keeping its natural look.
Supports the Wood
Oiling a wood allows boosting its dimensional security durably, therefore lowering the sensations of contortion (tiling, swelling, as well as contraction), cracking, or surface area splitting.
All-natural as well as Ecological
Choosing an “Oleobois” protective oil indicates selecting a healthy and balanced and eco-friendly remedy; the make-up leaves out fungicides, turpentine, and any kind of petroleum by-products frequently used (paraffin, white spirit, …).
Easy and also Economical Maintenance
Maintenance is very easy since once fueled oil; wood does not need to be removed or sanded before remodelling: a cleansing with black soap complied with by a simple re-oiled surface is enough. Diy Pottery Barn Diy Furniture
Greying of The Timber
What Is Timber Graying?
Wood is a product almost comprised of polysaccharides (cellulose and also hemicelluloses) and also lignins that will be broken down under ultraviolet photons’ action. This photodegradation of the lignins, which is likewise accentuated in the visibility of water, is accountable for the development of the shade of the wood. Greying is observed on the lumber utilized outdoors with no physical security and UV protection. This sensation triggers an adjustment in the original shade of the raw wood over time, which often tends to come to be gray.
What Are the Consequences of Greying?
Greying or graying, which is a very superficial sensation, only affects the wooden framework’s aesthetics. It does not indicate an architectural alteration and also does not impact the strength of the product. The look of this phenomenon is restricted to the surface of the timber. The loss of structural sturdiness (which can reach the ruin of the material) is, for its component, due to attacks of organic origin that impact the wood in its mass.
Is it possible to prevent the greying of the wood without maintaining it?
NO – Without completing products and without upkeep, it would certainly be illusory to claim to be able to stop the timber from greying.
Will the application of a finish protect against the wood from transforming gray?
YES – If this application is made on a regular basis, it is possible to avoid this phenomenon. The hydrophobic nature of the oil highly restricts the timber’s affinity for water as well as as a result postpones its action. Diy Pottery Barn Diy Furniture
Corrected as well as Thermo-Oiled Timber
Several current procedures have made it possible to boost the resilience and dimensional stability of various other types dramatically: these are high-temperature heat treatments (210 to 250 ° C )in several phases, carried out in special heating systems, either under an inert atmosphere with nitrogen (fixed timber) or with water vapor shots (Finnish heat-treated lumber). The wood takes on a beautiful brown shade as well as comes to be hydrophobic as well as very resistant to fungal or insect attacks. Nonetheless, the heat damages these woods a little, which can not be utilized for architectural objectives (generally in home siding, parquet, and also terrace boards).
The supposed homeothermic process does not have this negative aspect: the wood is just warmed up to 130 ° C, with an immersion in a mixture based upon linseed oil as well as grease derivatives, which permits a deep impregnation. This likewise ensures a longer resistance to greying and also does not need normal upkeep. The process creators have actually started to market it in France: three suppliers in the wood market have currently bought it, and 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 then by saturating at 140 ° C in a combination of vegetable oil derivatives as well as acetic acid.

High-temperature therapies make the timber wholly water resistant and fungi immune.
The timber is given a temperature in between 210 ° C and 250 ° C in special ovens. It after that alters color to become darker. The major downside is that it sheds its stamina. It can after that just be utilized for cladding or floor covering.
Oleothermy is a treatment that includes 3 phases: home heating to 130 ° C in a rapeseed oil bathroom, cooling down in a linseed oil bath, and drying. Because the home heating temperature is lower than the previous technique, the wood is much less breakable.
Studies have revealed 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 cleaning. Hence, the homeothermic makes it possible to take care of the molecule and also make the timber a lot more resistant to flames, water, and also shocks. For more information about this technique, here is a doctoral thesis that was done on the topic.
Oils, Discolorations, and also Paints
The resilience of particular species such as oak and also chestnut is mainly due to their high tannin material. Nevertheless, these are gradually washed out by rainwater, which is a little acidic. Like other types, oak and chestnut, consequently, call for surface security. Linseed oil with a little turpentine included – to be used in heat (it permeates better) – is classic and also cost-effective defense, water-repellent, as well as hold-ups greying.
Organic wood discolorations, which are colored yet reveal the timber grain, supply better protection versus UV rays thanks to the pigments they have. They should be restored every 3 to 5 years for the south facades as well as every 8 to 10 years for the north exteriors. Unlike paints, they do not need sanding before renewal (a brush stroke suffices to remove the pigment dirt). When it comes to natural lacquer paints, they give more long lasting protection given that they contain fillers (particularly chalk) that create an entire screen against UV rays. It’s a little bit like sun creams; the safety relies on the screen’s quality and also the direct exposure. Diy Pottery Barn Diy Furniture
Surface area Security
To boost the durability of outside wood normally, choose a discolor, as an example, a mixture of linseed oil and also turpentine. Some readily readily available wood spots are tinted as well as offer small UV protection. The benefit of this approach is that no sanding is called for.
For also much better protection, use natural lacquer paint. It will certainly offer optimal security against ultraviolet rays– favor microporous paints containing chalk fillers to let the wood take a breath.
Protecting outside timber normally can be done with a protective tarnish or warmth therapy. The selection of method depends upon the qualities that you desire to modify. If certain timber varieties can be used without protection, they should be stained after a certain duration since the protective tannins will certainly have disappeared. If you do refrain this, you will have to have an expert wetness treatment.
Protecting Timber from Water
Safeguarding wood from water is a crucial function of an outside coating before any type of decorative aspect. It is recommended to conserve the product with paint, varnish, stain, saturator, or oil. It is essential to accomplish a genuine obstacle impact, which should be water resistant if the timber is not to wear away as well rapidly.
This makes it feasible to preserve natural, solid, raw, or veneered wood essentially over time. It is secured to maintain for years when faced with the different weather aggressiveness encountered. It is durably preserved from humidity, rainfall, bad climate, light, sun, and also ultraviolet rays, making it age too soon. Diy Pottery Barn Diy Furniture
Continue To Be Normally Absorptive to Dampness
Continue to be moisture permeableStaying normally absorptive to smoke is extremely important. Timber is made up of plant fibers that have an excellent fondness with water. It is, consequently, a fragile material that stays easily absorptive to water. It continues to be especially sensitive to numerous fluids that penetrate it.
Timber takes in really promptly the moisture that is present in the ambient environment. It absorbs water before naturally launching it because it is a hygroscopic product. It remains in constant balance with its environment, whatever the wetness content.
These various humidity variations go to the origin of the normal dimensional transformations of wood. They have the effect of triggering deformations that can sometimes be significant. It works by swelling if the air is too humid. It diminishes when the ambience ends up being drier.
Rainfall, showers, thunderstorms, and various other bad weather condition that are in contact with the wood can cause the appearance of unattractive stains, streaks, trickles, and halos. Moisture, seepage, condensation, and also water vapor are likewise in charge of the early aging of wood throughout the years. Diy Pottery Barn Diy Furniture
Do Not Stop Exchanges with The Outside World.
Do not prevent exchanges with the outdoors not prevent communications with the outside; it must be valued. When you want to secure the wood, a water-repellent product must be related to stay clear of water from penetrating it. It needs to be ensured that it is not impregnated by wetness if it is to last over the long term.
A wood therapy product can only be completely appropriate if it values the various moisture exchanges. The timber has to be able to remain to regulate itself with its environment. It is important to guarantee that the movie remains adequately micro-porous to guarantee an excellent exchange performance.
On the other hand, impermeability and water rigidity must not be puzzled, which are really different ideas. Waterproofing has to be restricted when it comes to timber protection. Making a wood entirely watertight may cause the product to rot in the long-term.
Gas exchange, which manages the dampness content in the wood’s pores, have to never ever be stopped. A timber paint should permit the substrate to breathe without ever quiting the interior discharge to the exterior. It should simply stop water from passing through the heart of the timber, not to alter or deteriorate it.
Choosing a Right Timber Treatment Item
Choosing a timber treatment choosing the appropriate timber treatment product is essential to shield timber efficiently in time. There are various kinds of products that can successfully preserving this material. One can use an item that permeates deeply, such as oil, impregnation, or saturator.
A penetrating treatment gives more efficient security than an item that deposits a film externally, such as paint, varnish, or sealant, for instance. Certainly, while a film-forming item may seem valuable originally, this is not constantly the situation in the long term.
They can end up cracking, flaking, splitting, or peeling off over the years. Seepage, water, or humidity permeates the product, which becomes inadequately protected. 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 utilized in wood waterproofing items. These harmful compounds should be avoided similarly as oil solvents, which are still existing in several products. They are not harmless to the individual, the setting, or nature. It is better to pick a bio-sourced product of plant beginning that is consistent with this all-natural product.

Keep Routinely for Adequate Security.
Maintain for good defense keep regularly for an adequate protection, remains a procedure that must not be forgotten to carry out. Despite the type of waterproofing picked to preserve the wood, it is necessary to preserve it routinely to ensure that the security stays completely effective gradually.
Tedious prep work, fining sand, gritting, or removing of the surface area can be stayed clear of making use of an oil, saturator, or impregnation. They have the particularity of securing the product throughout its mass without producing a movie on the surface that can exfoliate afterward.
A waterproofing representative’s function is to protect the timber from spots, marks, rings, as well as day-to-day wear and tear. It is generally connected with an anti UV agent that will certainly avoid the timber from coming to be also grey in the long run. It therefore limits the phenomenon of swelling or shrinking.
A non-film-forming water repellent has several advantages for maintaining a wooden surface area. It is really reliable against negative climate thanks to an obstacle effect. Additionally, it stays very effective in nourishing the wood in all its deepness to the product’s very heart. It additionally secures the assistance from light, sunlight, and also ultraviolet rays.
