Outdoor wood has two main opponents: UV (ultraviolet rays from sunlight) and moisture. The first causes a sort of superficial shed – like on our skin, leading to tiny splits as well as greying. Absolutely nothing dramatic, the damage is primarily visual, and the wood is not influenced in depth. Hand Drafted Furniture Plan
Dampness presents a lot more severe issues: if rain does not run off or does not evaporate rapidly, if the wood stays in contact with the ground or if the moisture can climb by capillary activity, the moisture material of the wood will allow the installment of lignivorous fungis that are forerunners to rot and also favor strikes by wood-eating pests. Can chemical preservative treatments be prevented?
Sturdy Types, without Sapwood
Some naturally durable species from our areas can be utilized without treatment when the wood is laid vertically (risk class 3) and allows good water drain (cladding, home windows, shutters): specifically Douglas, larch, chestnut, oak, as well as grasshopper. Just the last three types are recommended when the timber is laid horizontally (balcony or balcony boards) or touching the ground (risk course 4). These woods have to likewise be chosen as well as cut in such a means as to eliminate the sapwood, the peripheral part of the trunk abundant in sugars, which draws in wood-eating bugs.

What Are the Benefits of Securing Your Timber?
Embellishes and also Secures
Past preserving the aesthetic element in time, making use of a timber oil or a saturator in the defense of wood will restore its initial shade and also enhance the grain of the timber while preserving its natural look.
Supports the Timber
Oiling a timber permits enhancing its dimensional stability durably, thus reducing the phenomena of contortion (tiling, swelling, and also shrinking), splitting, or surface area splitting.
Natural as well as Ecological
Picking an “Oleobois” safety oil implies selecting a healthy and also eco-friendly solution; the composition leaves out fungicides, turpentine, and also any kind of petroleum derivatives often used (paraffin, white spirit, …).
Easy as well as Economical Maintenance
Upkeep is simple since once oiled; wood does not need to be removed or sanded prior to renovation: a cleansing with black soap followed by an easy re-oiled surface is enough. Hand Drafted Furniture Plan
Greying of The Wood
What Is Timber Graying?
Timber is a material virtually comprised of polysaccharides (cellulose and also hemicelluloses) as well as lignins that will be degraded under ultraviolet photons’ action. This photodegradation of the lignins, which is additionally accentuated in the existence of water, is in charge of the evolution of the shade of the wood. Greying is observed on the wood used outdoors without any physical protection and UV security. This sensation creates a modification in the original color of the raw timber gradually, which tends to come to be gray.
What Are the Consequences of Greying?
Greying or graying, which is a very shallow sensation, just impacts the wood framework’s looks. It does not show a structural alteration and does not influence the strength of the material. The appearance of this sensation is limited to the surface area of the timber. The loss of structural resilience (which can go as far as the ruin of the material) is, for its part, as a result of attacks of biological beginning that impact the timber in its mass.
Is it possible to stay clear of the greying of the wood without preserving it?
NO – Without finishing products and without maintenance, it would certainly be illusory to claim to be able to avoid the wood from greying.
Will the application of a surface stop the wood from transforming gray?
YES – If this application is made on a regular basis, it is possible to prevent this sensation. The hydrophobic nature of the oil highly limits the wood’s fondness for water and also as a result postpones its activity. Hand Drafted Furniture Plan
Remedied and also Thermo-Oiled Wood
A number of recent processes have actually made it feasible to improve the resilience as well as dimensional security of other varieties considerably: these are high-temperature warm therapies (210 to 250 ° C )in numerous phases, carried out in special heating systems, either under an inert environment with nitrogen (corrected wood) or with water vapor injections (Finnish heat-treated lumber). The wood handles a stunning brown shade and also becomes hydrophobic and also really resistant to fungal or insect attacks. The high temperature compromises these woods a little, which can not be made use of for architectural purposes (mainly in siding, parquet, and balcony boards).
The supposed homeothermic procedure does not have this disadvantage: the timber is only heated up to 130 ° C, with an immersion in a combination based on linseed oil as well as grease derivatives, which enables a deep impregnation. This also guarantees a longer resistance to greying and does not need normal upkeep. The process makers have begun to market it in France: 3 producers in the wood sector have actually currently bought it, and also others remain in the pipe. The recent Wood-Protect process patented by Lapeyre and also INRA-INPT in Toulouse is of the exact same type, with impregnation by autoclave and then by saturating at 140 ° C in a mixture of vegetable oil by-products as well as acetic acid.

High-temperature treatments make the wood wholly water resistant and fungus immune.
The timber is brought to a temperature between 210 ° C and also 250 ° C in special ovens. It then alters color to end up being darker. The major downside is that it sheds its strength. It can then only be made use of for cladding or flooring.
Oleothermy is a treatment that contains 3 stages: home heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bath, and drying out. Given that the home heating temperature is less than the previous method, the wood is less breakable.
Researches have actually revealed that homeothermic home heating is useful when done after boron therapy. Boron has anti-inflammatory properties. The trouble is that it is not immune to washing. Thus, the homeothermic makes it feasible to fix the molecule and make the wood 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, Discolorations, and also Paints
The sturdiness of specific types such as oak and also chestnut is mostly because of their high tannin content. These are gradually washed out by rain, which is somewhat acidic. Like other varieties, oak as well as chestnut, therefore, need surface area protection. Linseed oil with a little turpentine added – to be utilized in heat (it passes through far better) – is classic and low-cost protection, water-repellent, and delays greying.
Organic wood spots, which are colored however reveal the wood grain, offer far better protection against UV rays thanks to the pigments they have. Nonetheless, they should be restored every 3 to 5 years for the south facades as well as every 8 to one decade for the north exteriors. Unlike paints, they do not require sanding before renewal (a brush stroke suffices to get rid of the pigment dirt). When it comes to organic lacquer paints, they supply more sturdy defense because they contain fillers (particularly chalk) that develop an entire display versus UV rays. It’s a little bit like sun creams; the safety depends on the display’s quality and also the direct exposure. Hand Drafted Furniture Plan
To enhance the longevity of outside wood normally, opt for a discolor, as an example, a combination of linseed oil and also turpentine. Some commercially offered timber spots are tinted and also give mild UV security. The benefit of this method is that no sanding is called for.
For even far better defense, apply organic lacquer paint. It will provide ideal defense versus ultraviolet rays– favor microporous paints including chalk fillers to allow the timber breathe.
Shielding external wood naturally can be made with a protective stain or heat treatment. The option of technique depends upon the features that you want to modify. If certain timber species can be made use of without security, they have to be tarnished after a particular duration because the protective tannins will certainly have disappeared. If you do not do this, you will have to have a specialist wetness treatment.
Protecting Wood from Water
Protecting timber from water is a vital function of an outside coating before any kind of decorative aspect. It is suggested to conserve the material with paint, varnish, discolor, saturator, or oil. Indeed, it is essential to attain a genuine barrier effect, which need to be water-proof if the wood is not to degrade also quickly.
This makes it possible to maintain natural, solid, raw, or veneered wood basically with time. It is shielded to keep for years in the face of the different climatic aggressions encountered. It is durably maintained from moisture, rainfall, negative climate, light, sun, and also ultraviolet rays, making it age too soon. Hand Drafted Furniture Plan
Continue To Be Naturally Absorptive to Wetness
Stay wetness permeableStaying normally permeable to smoke is extremely essential. Timber is composed of plant fibers that have an exceptional fondness with water. It is, as a result, a vulnerable product that continues to be easily permeable to water. It continues to be specifically conscious numerous fluids that permeate it.
Timber soaks up really quickly the humidity that exists in the ambient atmosphere. It takes in water prior to normally releasing it because it is a hygroscopic material. It stays in consistent equilibrium with its atmosphere, whatever the moisture material.
These various humidity variations are at the origin of the typical dimensional transformations of wood. They have the impact of causing deformations that can occasionally be significant. It works by swelling if the air is too humid. It diminishes when the atmosphere ends up being drier.
Rain, showers, electrical storms, as well as various other bad weather condition that touch with the timber can create the look of unpleasant stains, touches, trickles, and also halos. Wetness, infiltration, condensation, and water vapor are additionally in charge of the premature aging of wood over the years. Hand Drafted Furniture Plan
Do Not Stop Exchanges with The Outside World.
Do not avoid exchanges with the outdoors not protect against interactions with the outside; it must be appreciated. When you intend to safeguard the timber, a water-repellent item needs to be related to stay clear of water from permeating it. It has to be ensured that it is not fertilized by dampness if it is to last over the long-term.
A timber therapy item can only be flawlessly suitable if it appreciates the various moisture exchanges. The timber needs to have the ability to continue to control itself with its atmosphere. It is essential to guarantee that the film remains sufficiently micro-porous to guarantee an excellent exchange performance.
On the other hand, impermeability and water tightness need to not be perplexed, which are really different concepts. Waterproofing should be prohibited in the case of timber defense. Making a timber totally watertight may create the product to rot in the long-term.
Gas exchange, which regulates the dampness content in the wood’s pores, have to never be avoided. A timber paint must permit the substrate to breathe without ever before stopping the internal discharge to the outside. It has to simply prevent water from permeating the heart of the timber, not to modify or deteriorate it.
Selecting a Right Wood Treatment Product
Picking a wood therapy choosing the appropriate wood treatment item is vital to safeguard timber successfully over time. There are various types of items that can effectively preserving this product. One can use a product that penetrates deeply, such as oil, impregnation, or saturator.
A permeating therapy gives much more reliable protection than a product that deposits a film on the surface, such as paint, varnish, or sealer, as an example. While a film-forming product may seem valuable originally, this is not always the case in the long term.
They can finish up splitting, flaking, splitting, or peeling off over the years. Seepage, water, or moisture passes through the product, which comes to be inadequately insulated. It is then important to sand or strip the surface area of the wood to bare it again to be preserved.
Silicones are extensively utilized in timber waterproofing products. These dangerous compounds should be stayed clear of similarly as petroleum solvents, which are still present in several products. They are not harmless to the user, the setting, or nature. It is far better to pick a bio-sourced product of plant origin that follows this all-natural product. Hand Drafted Furniture Plan
Preserve Regularly for Adequate Defense.
Maintain completely protection keep frequently for an ample protection, stays an operation that must not be neglected to carry out. No matter the type of waterproofing picked to protect the timber, it is essential to keep it routinely to make sure that the protection remains sufficiently effective in time.
Laborious prep work, fining sand, gritting, or removing of the surface can be prevented utilizing an oil, saturator, or impregnation. They have the particularity of shielding the product throughout its mass without producing a movie externally that can flake off afterward.
A waterproofing representative’s feature is to secure the wood from discolorations, marks, rings, as well as daily deterioration. It is generally connected with an anti UV agent that will avoid the wood from coming to be also grey in the future. It hence restricts the sensation of swelling or contraction.
A non-film-forming water repellent has lots of advantages for protecting a wood surface. It is really reliable against poor weather thanks to a barrier impact. It stays very efficient in nurturing the timber in all its depth to the product’s actual heart. It additionally safeguards the assistance from light, sunlight, and also ultraviolet rays.
