Exterior timber has two primary adversaries: UV (ultraviolet rays from sunshine) as well as moisture. The first causes a sort of superficial shed – like on our skin, causing little splits and also greying. Nothing remarkable, the damage is mostly aesthetic, and the wood is not affected in depth.

Dampness positions much more extreme problems: if rain does not run or does not vaporize promptly, if the wood continues to be in contact with the ground or if the moisture can rise by capillary action, the dampness web content of the wood will certainly permit the installment of lignivorous fungis that are precursors to rot as well as support attacks by wood-eating pests. Can chemical preservative treatments be prevented?
Resilient Variety, without Sapwood
Some normally resilient varieties from our areas can be used without treatment when the wood is laid up and down (threat course 3) and also allows great water drainage (cladding, 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 balcony boards) or in contact with the ground (threat course 4). These timbers have to likewise be chosen and cut in such a way as to get rid of the sapwood, the outer part of the trunk rich in sugars, which attracts wood-eating bugs. Furniture Plan Software Free
What Are the Benefits of Shielding Your Timber?
Embellishes and Protects
Beyond preserving the aesthetic facet in time, using a timber oil or a saturator in the defense of timber will restore its original color and boost the grain of the wood while preserving its natural appearance.
Maintains the Timber
Oiling a wood permits enhancing its dimensional security durably, therefore minimizing the sensations of contortion (tiling, swelling, and shrinkage), breaking, or surface splitting.
Natural and Ecological
Choosing an “Oleobois” safety oil implies choosing a healthy and eco-friendly option; the make-up omits fungicides, turpentine, and any oil derivatives regularly used (paraffin, white spirit, …).
Easy and also Economical Maintenance
Maintenance is easy since when fueled oil; wood does not need to be removed or fined sand before renovation: a cleansing with black soap complied with by a straightforward re-oiled surface is enough. Furniture Plan Software Free
Greying of The Timber
What Is Wood Graying?
Wood is a material virtually composed of polysaccharides (cellulose as well as hemicelluloses) and lignins that will certainly be degraded under ultraviolet photons’ activity. This photodegradation of the lignins, which is also accentuated in the existence of water, is accountable for the advancement of the shade of the wood. Greying is observed on the hardwood utilized outdoors with no physical defense as well as UV defense. This sensation creates a change in the initial shade of the raw wood in time, which has a tendency to end up being grey.
What Are the Effects of Greying?
Greying or graying, which is a very surface phenomenon, only impacts the wood structure’s aesthetic appeals. It does not suggest an architectural change as well as does not impact the strength of the product. The appearance of this phenomenon is limited to the surface area of the wood. The loss of structural longevity (which can go as far as the spoil of the material) is, for its part, due to strikes of biological beginning that impact the timber in its mass.
Is it feasible to avoid the greying of the wood without maintaining it?
NO – Without completing items and without maintenance, it would certainly be illusory to claim to be able to prevent the wood from greying.
Will the application of a coating stop the wood from transforming gray?
YES – If this application is made consistently, it is feasible to prevent this sensation. The hydrophobic nature of the oil highly restricts the timber’s fondness for water as well as consequently postpones its activity. Furniture Plan Software Free
Rectified and also Thermo-Oiled Timber
Several recent procedures have made it feasible to enhance the sturdiness and dimensional security of other types substantially: these are high-temperature warmth therapies (210 to 250 ° C )in several phases, carried out in unique furnaces, either under an inert atmosphere with nitrogen (remedied timber) or with water vapor injections (Finnish heat-treated lumber). The timber takes on a stunning brownish color as well as ends up being hydrophobic as well as very resistant to fungal or insect assaults. The high temperature level deteriorates these woods a little, which can not be made use of for structural functions (mostly in home siding, parquet, and also terrace boards).
The so-called homeothermic procedure does not have this negative aspect: the timber is just warmed up to 130 ° C, with an immersion in a combination based on linseed oil as well as grease derivatives, which allows a deep impregnation. This likewise makes sure a longer resistance to greying and does not need routine upkeep. The procedure designers have actually started to market it in France: 3 suppliers in the timber sector have actually currently bought it, and others are in the pipe. The recent Wood-Protect procedure patented by Lapeyre as well as INRA-INPT in Toulouse is of the same kind, with impregnation by autoclave and then by soaking at 140 ° C in a combination of grease derivatives as well as acetic acid.

High-temperature therapies make the timber entirely waterproof as well as fungus immune.
The timber is given a temperature level between 210 ° C and 250 ° C in special stoves. It after that changes color to come to be darker. The primary drawback is that it sheds its stamina. It can after that just be utilized for cladding or floor covering.
Oleothermy is a therapy that consists of 3 stages: home heating to 130 ° C in a rapeseed oil bath, cooling down in a linseed oil bathroom, and also drying out. Since the home heating temperature level is less than the previous technique, the wood is much less brittle.
Researches have actually revealed that homeothermic heating is valuable when done after boron therapy. Boron has anti-inflammatory residential or commercial properties. The problem is that it is not resistant to washing. Therefore, the homeothermic makes it feasible to fix the molecule as well as make the wood much more resistant to flames, water, and also shocks. To learn more about this method, here is a doctoral thesis that was done on the topic.
Oils, Discolorations, as well as Paints
The resilience of certain types such as oak and also chestnut is mostly because of their high tannin web content. However, these are slowly rinsed by rainwater, which is a little acidic. Like various other types, oak and also chestnut, consequently, need surface area defense. Linseed oil with a little turpentine added – to be made use of in hot weather (it permeates much better) – is traditional and economical protection, water-repellent, as well as delays greying.
Organic timber spots, which are tinted but reveal the timber grain, give far better defense against UV rays thanks to the pigments they contain. Nevertheless, they need to be renewed every 3 to 5 years for the south exteriors as well as every 8 to one decade 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 give more resilient protection given that they consist of fillers (particularly chalk) that develop an entire screen versus UV rays. It’s a little bit like sun creams; the security depends upon the display’s high quality and also the direct exposure. Furniture Plan Software Free
To improve the resilience of outside timber naturally, go with a tarnish, for instance, a blend of linseed oil and turpentine. Some commercially readily available wood discolorations are colored and supply minor UV security. The benefit of this technique is that no sanding is needed.
For also better security, use natural lacquer paint. It will offer optimal defense against ultraviolet rays– prefer microporous paints containing chalk fillers to allow the wood breathe.
Protecting exterior wood naturally can be made with a protective discolor or heat treatment. The selection of technique relies on the features that you wish to customize. If certain wood types can be used without protection, they need to be discolored after a specific period because the safety tannins will certainly have disappeared. If you do refrain from doing this, you will certainly have to have a professional moisture therapy.
Safeguarding Timber from Water
Protecting timber from water is an essential function of an exterior surface before any type of decorative aspect. It is advised to conserve the material with paint, varnish, tarnish, saturator, or oil. It is vital to achieve an actual barrier result, which have to be waterproof if the wood is not to deteriorate too swiftly.
This makes it possible to maintain all-natural, solid, raw, or veneered wood practically with time. It is protected to keep for many years despite the numerous climatic aggressions encountered. It is durably protected from moisture, rain, poor climate, light, sun, and also ultraviolet rays, making it age prematurely. Furniture Plan Software Free
Stay Normally Permeable to Wetness
Continue to be dampness permeableStaying normally permeable to smoke is very vital. Timber is composed of plant fibers that have a superb fondness with water. It is, as a result, a breakable material that continues to be quickly permeable to water. It remains particularly sensitive to various fluids that permeate it.
Wood soaks up extremely quickly the humidity that is present in the ambient environment. It absorbs water prior to normally releasing it since it is a hygroscopic material. It remains in consistent equilibrium with its setting, whatever the dampness content.
These different humidity variants go to the origin of the usual dimensional improvements of timber. They have the effect of causing deformations that can occasionally be significant. It works by swelling if the air is as well moist. It diminishes when the environment ends up being drier.
Rain, showers, electrical storms, and various other negative climate that touch with the timber can trigger the look of undesirable spots, touches, leaks, as well as halos. Dampness, infiltration, condensation, as well as water vapor are also in charge of the early aging of wood for many years. Furniture Plan Software Free
Do Not Protect against Exchanges with The Outdoors.
Do not protect against exchanges with the outside not avoid interactions with the exterior; it must be valued. When you intend to secure the wood, a water-repellent item has to be put on avoid water from penetrating it. It has to be ensured that it is not fertilized by wetness if it is to last over the long term.
A timber treatment product can just be perfectly ideal if it appreciates the different moisture exchanges. The wood needs to have the ability to continue to regulate itself with its atmosphere. It is vital to guarantee that the movie continues to be adequately micro-porous to guarantee a good exchange performance.
On the other hand, impermeability as well as water rigidity need to not be perplexed, which are really various notions. Waterproofing has to be banned when it comes to wood defense. Making a wood completely watertight might create the material to rot in the long term.
Gas exchange, which controls the wetness material in the wood’s pores, need to never ever be avoided. A wood paint must enable the substratum to breathe without ever stopping the inner emptying to the outside. It should simply avoid water from penetrating the heart of the wood, not to change or deteriorate it.
Choosing a Right Wood Therapy Product
Choosing a timber therapy choosing the best wood treatment item is essential to protect wood successfully over time. There are various types of items that are capable of successfully preserving this material. One can make use of a product that passes through deeply, such as oil, impregnation, or saturator.
A passing through treatment provides extra effective protection than an item that deposits a film on the surface, such as paint, varnish, or sealant. While a film-forming item may seem helpful initially, this is not constantly the situation in the lengthy term.
They can finish up fracturing, flaking, splitting, or peeling off over the years. Seepage, water, or moisture permeates the material, which ends up being improperly protected. It is after that vital to sand or strip the surface area of the wood to bare it once more to be preserved.
Silicones are widely used in wood waterproofing products. These dangerous compounds should be prevented in the same way as petroleum solvents, which are still existing in lots of products. They are not harmless to the user, the environment, or nature. It is better to pick a bio-sourced item of plant beginning that follows this all-natural product. Furniture Plan Software Free
Maintain Frequently for Adequate Defense.
Maintain for good security preserve regularly for an appropriate defense, continues to be an operation that ought to not be failed to remember to execute. No matter the type of waterproofing selected to preserve the wood, it is required to maintain it regularly to make sure that the protection stays sufficiently reliable over time.
Tedious prep work, sanding, gritting, or stripping of the surface area can be prevented using an oil, saturator, or impregnation. They have the particularity of securing the product throughout its mass without producing a film on the surface that can exfoliate afterward.
A waterproofing agent’s feature is to shield the timber from discolorations, marks, rings, as well as daily wear and tear. It is generally connected with an anti UV representative that will certainly stop the timber from becoming also grey in the long run. It thus limits the sensation of swelling or shrinkage.
A non-film-forming water repellent has numerous benefits for maintaining a wood surface. It is extremely efficient against negative climate thanks to an obstacle effect. It continues to be really efficient in nourishing the wood in all its depth to the material’s very heart. It also shields the support from light, sun, and ultraviolet rays.
