Outside wood has 2 major adversaries: UV (ultraviolet rays from sunshine) and also moisture. The first causes a kind of surface shed – like on our skin, resulting in small splits and also greying. Nothing dramatic, the damage is primarily visual, and the wood is not influenced detailed. Furniture Plan Drawing
Moisture positions a lot more severe issues: if rainwater does not run or does not evaporate rapidly, if the wood continues to be in contact with the ground or if the dampness can increase by capillary activity, the dampness content of the wood will certainly permit the installment of lignivorous fungis that are forerunners to rot and support strikes by wood-eating insects. Can chemical preservative treatments be stayed clear of?
Long lasting Types, without Sapwood
Some normally durable types from our regions can be utilized without treatment when the wood is laid vertically (risk class 3) as well as enables good water drainage (cladding, home windows, shutters): specifically Douglas, larch, chestnut, oak, and also locust. Only the last 3 varieties are recommended when the wood is laid horizontally (veranda or balcony boards) or touching the ground (risk class 4). These timbers have to also be selected and cut in such a means as to remove the sapwood, the outer part of the trunk rich in sugars, which draws in wood-eating insects. Furniture Plan Drawing
What Are the Benefits of Safeguarding Your Timber?
Embellishes and Secures
Beyond preserving the visual facet in time, utilizing a wood oil or a saturator in the security of timber will revive its original shade and also boost the grain of the timber while maintaining its all-natural look.
Supports the Wood
Fueling oil a wood enables improving its dimensional stability durably, hence reducing the phenomena of deformation (tiling, swelling, and also shrinkage), breaking, or surface area splitting.
Natural and also Ecological
Selecting an “Oleobois” protective oil implies choosing a healthy and balanced and also environmentally friendly service; the composition excludes fungicides, turpentine, and any type of oil derivatives often used (paraffin, white spirit, …).
Easy as well as Economical Upkeep
Upkeep is simple because when fueled oil; timber does not require to be stripped or fined sand prior to renovation: a cleaning with black soap followed by an easy re-oiled surface is enough. Furniture Plan Drawing
Greying of The Timber
What Is Wood Graying?
Timber is a material nearly comprised of polysaccharides (cellulose and also hemicelluloses) as well as lignins that will certainly be weakened under ultraviolet photons’ action. This photodegradation of the lignins, which is also accentuated in the presence of water, is in charge of the advancement of the shade of the timber. Greying is observed on the lumber utilized outdoors without any physical security and also UV security. This sensation causes a change in the original shade of the raw timber with time, which has a tendency to end up being grey.
What Are the Consequences of Greying?
Greying or graying, which is a really surface sensation, just influences the wood structure’s looks. It does not indicate an architectural alteration and does not influence the solidity of the material. The look of this sensation is restricted to the surface of the timber. The loss of architectural durability (which can go as far as the wreck of the material) is, for its component, because of assaults of biological origin that affect the wood in its mass.
Is it feasible to prevent the greying of the timber without preserving it?
NO – Without ending up products and without maintenance, it would certainly be illusory to claim to be able to stop the wood from greying.
Will the application of a surface stop the wood from transforming gray?
YES – If this application is made regularly, it is possible to prevent this sensation. The hydrophobic nature of the oil strongly limits the wood’s affinity for water as well as for that reason postpones its action. Furniture Plan Drawing
Corrected and Thermo-Oiled Wood
Numerous current processes have made it possible to boost the longevity as well as dimensional security of various other species substantially: these are high-temperature warm treatments (210 to 250 ° C )in a number of stages, carried out in special heaters, either under an inert ambience with nitrogen (rectified wood) or with water vapor shots (Finnish heat-treated lumber). The timber takes on an attractive brownish shade as well as becomes hydrophobic as well as extremely immune to fungal or insect strikes. However, the heat deteriorates these woods a little, which can not be made use of for architectural objectives (primarily in siding, parquet, and balcony boards).
The supposed homeothermic procedure does not have this drawback: the timber is only heated up to 130 ° C, with an immersion in a mix based upon linseed oil and grease by-products, which permits a deep impregnation. This additionally makes sure a longer resistance to greying as well as does not require normal maintenance. The procedure designers have actually begun to market it in France: 3 suppliers in the timber sector have actually already bought it, and others are in the pipeline. The current Wood-Protect process patented by Lapeyre and INRA-INPT in Toulouse is of the exact same kind, with impregnation by autoclave and after that by soaking at 140 ° C in a mixture of grease derivatives and acetic acid.

High-temperature treatments make the timber entirely water resistant as well as fungi immune.
The wood is given a temperature between 210 ° C and also 250 ° C in unique ovens. It after that alters color to come to be darker. The major downside is that it loses its strength. It can after that just be utilized for cladding or flooring.
Oleothermy is a treatment that consists of 3 phases: home heating to 130 ° C in a rapeseed oil bath, cooling in a linseed oil bathroom, as well as drying. Because the home heating temperature level is less than the previous method, the wood is less brittle.
Researches have shown that homeothermic heating is beneficial when done after boron therapy. Boron has anti-inflammatory buildings. The trouble is that it is not resistant to washing. Therefore, the homeothermic makes it feasible to repair the molecule and also make the timber much more immune to flames, water, as well as shocks. To learn more regarding this technique, below is a doctoral thesis that was done on the topic.
Oils, Stains, as well as Paints
The toughness of particular types such as oak and chestnut is generally due to their high tannin content. Nevertheless, these are slowly washed out by rain, which is slightly acidic. Like various other types, oak as well as chestnut, therefore, need surface defense. Linseed oil with a little turpentine included – to be used in heat (it permeates better) – is timeless and affordable defense, water-repellent, and delays greying.
Organic wood stains, which are tinted but show the wood grain, supply better protection against UV rays thanks to the pigments they have. Nonetheless, they ought to be restored every 3 to 5 years for the south facades and also every 8 to ten years for the north exteriors. Unlike paints, they do not need sanding before revival (a brush stroke suffices to eliminate the pigment dirt). When it comes to organic lacquer paints, they give more durable security given that they have fillers (especially chalk) that form an entire display against UV rays. It’s a little bit like sun creams; the safety depends upon the screen’s quality as well as the direct exposure. Furniture Plan Drawing
Surface area Security
To enhance the longevity of exterior timber naturally, select a tarnish, for example, a blend of linseed oil and turpentine. Some commercially available wood stains are colored as well as supply mild UV protection. The benefit of this method is that no sanding is needed.
For even much better defense, use natural lacquer paint. It will supply optimum defense versus ultraviolet rays– prefer microporous paints including chalk fillers to let the wood breathe.
Shielding external timber normally can be finished with a safety tarnish or warmth treatment. The option of technique depends upon the features that you want to customize. If certain wood varieties can be made use of without defense, they must be stained after a particular period since the protective tannins will certainly have vanished. If you do refrain from doing this, you will certainly need to have an expert dampness therapy.
Protecting Timber from Water
Protecting wood from water is an important feature of an outside finish before any type of ornamental element. It is suggested to conserve the material with paint, varnish, stain, saturator, or oil. It is necessary to attain a genuine obstacle effect, which must be water-proof if the timber is not to deteriorate too swiftly.
This makes it possible to maintain natural, solid, raw, or veneered timber basically over time. It is secured to keep for years despite the numerous weather aggressions came across. It is durably protected from humidity, rain, negative climate, light, sunlight, and also ultraviolet rays, making it age too soon. Furniture Plan Drawing
Remain Normally Permeable to Dampness
Remain moisture permeableStaying naturally absorptive to smoke is really crucial. Wood is composed of plant fibers that have an exceptional affinity with water. It is, consequently, a delicate product that remains conveniently absorptive to water. It continues to be especially sensitive to numerous liquids that permeate it.
Wood absorbs very quickly the moisture that exists in the ambient environment. It soaks up water before normally releasing it because it is a hygroscopic product. It stays in consistent balance with its atmosphere, whatever the dampness web content.
These different moisture variations are at the beginning of the normal dimensional changes of timber. They have the impact of causing deformations that can occasionally be significant. It works by swelling if the air is as well damp. It diminishes when the ambience becomes drier.
Rain, showers, thunderstorms, and also various other bad climate that touch with the timber can cause the look of unpleasant stains, touches, trickles, and halos. Wetness, seepage, condensation, and also water vapor are additionally in charge of the early aging of wood throughout the years. Furniture Plan Drawing
Do Not Protect against Exchanges with The Outdoors.
Do not avoid exchanges with the outdoors not avoid communications with the outside; it should be valued. When you want to safeguard the timber, a water-repellent item must be related to prevent water from permeating it. It should be ensured that it is not impregnated by wetness if it is to last over the long-term.
A timber therapy item can only be perfectly ideal if it values the various wetness exchanges. The timber should have the ability to continue to manage itself with its environment. It is vital to make certain that the film continues to be adequately micro-porous to assure a great exchange effectiveness.
On the other hand, impermeability as well as water rigidity ought to not be puzzled, which are really different concepts. Waterproofing has to be prohibited when it comes to wood protection. Making a timber completely watertight might create the product to rot in the long term.
Gas exchange, which manages the moisture content in the wood’s pores, need to never ever be protected against. A timber paint need to permit the substrate to take a breath without ever stopping the internal emptying to the exterior. It needs to just prevent water from permeating the heart of the wood, not to modify or weaken it.
Choosing a Right Timber Treatment Product
Picking a timber treatment picking the appropriate timber treatment product is essential to secure timber efficiently with time. There are different sorts of products that are capable of successfully protecting this product. One can make use of an item that permeates deeply, such as oil, impregnation, or saturator.
A penetrating therapy supplies much more efficient security than an item that deposits a movie on the surface area, such as paint, varnish, or sealant. While a film-forming product may appear useful originally, this is not constantly the case in the long term.
They can finish up cracking, flaking, cracking, or peeling off over the years. Infiltration, water, or moisture permeates the material, which ends up being badly insulated. It is after that important to sand or strip the surface of the wood to bare it once again to be preserved.
Silicones are commonly used in wood waterproofing items. These hazardous materials need to be stayed clear of in the same way as petroleum solvents, which are still existing in lots of items. They are not harmless to the individual, the environment, or nature. It is far better to pick a bio-sourced item of plant origin that is consistent with this all-natural material.

Maintain Routinely for Adequate Security.
Maintain permanently defense maintain regularly for an adequate defense, remains a procedure that ought to not be forgotten to perform. Regardless of the sort of waterproofing chosen to maintain the wood, it is necessary to preserve it regularly to ensure that the security stays completely reliable over time.
Tiresome prep work, sanding, gritting, or removing of the surface can be avoided using an oil, saturator, or impregnation. They have the particularity of shielding the material throughout its mass without creating a movie on the surface that can flake off afterward.
A waterproofing representative’s feature is to protect the timber from stains, marks, rings, and everyday deterioration. It is typically associated with an anti UV representative that will stop the wood from coming to be as well grey in the future. It therefore restricts the phenomenon of swelling or shrinking.
A non-film-forming water repellent has lots of advantages for protecting a wooden surface. It is really efficient versus bad climate thanks to a barrier result. Additionally, it remains extremely reliable in nourishing the timber in all its depth to the material’s actual heart. It also protects the support from light, sun, and ultraviolet rays.
