Exterior timber has 2 major enemies: UV (ultraviolet rays from sunlight) and also moisture. The first causes a sort of shallow burn – like on our skin, causing tiny splits as well as greying. Absolutely nothing remarkable, the damage is mostly aesthetic, and also the timber is not influenced detailed. Diy Photography Furniture
Moisture postures a lot more severe problems: if rainwater does not escape or does not vaporize rapidly, if the timber continues to be touching the ground or if the moisture can climb by capillary activity, the wetness content of the timber will enable the installation of lignivorous fungis that are forerunners to rot and also favor attacks by wood-eating insects. Can chemical preservative treatments be avoided?
Long lasting Types, without Sapwood
Some naturally sturdy types from our regions can be made use of without therapy when the wood is laid vertically (risk class 3) as well as allows excellent water drainage (cladding, windows, shutters): specifically Douglas, larch, chestnut, oak, and also grasshopper. Only the last three varieties are advised when the wood is laid horizontally (terrace or terrace boards) or touching the ground (threat class 4). These timbers need to likewise be selected as well as cut in such a method regarding get rid of the sapwood, the outer part of the trunk abundant in sugars, which draws in wood-eating bugs.

What Are the Benefits of Protecting Your Timber?
Embellishes as well as Safeguards
Past maintaining the visual element over time, utilizing a wood oil or a saturator in the security of wood will certainly revive its initial shade and also improve the grain of the timber while preserving its all-natural appearance.
Maintains the Wood
Oiling a timber allows improving its dimensional stability durably, therefore reducing the sensations of deformation (tiling, swelling, and also contraction), fracturing, or surface splitting.
All-natural and also Ecological
Picking an “Oleobois” safety oil suggests choosing a healthy and balanced as well as environmentally friendly remedy; the structure excludes fungicides, turpentine, and any oil derivatives frequently used (paraffin, white spirit, …).
Easy and Economical Upkeep
Maintenance is simple because once fueled oil; timber does not need to be stripped or sanded before renovation: a cleaning with black soap adhered to by an easy re-oiled surface is enough. Diy Photography Furniture
Greying of The Wood
What Is Timber Graying?
Timber is a material nearly comprised of polysaccharides (cellulose as well as hemicelluloses) as well as lignins that will be weakened under ultraviolet photons’ action. This photodegradation of the lignins, which is likewise highlighted in the existence of water, is in charge of the advancement of the color of the timber. Greying is observed on the timber made use of outdoors without any physical defense as well as UV protection. This phenomenon causes a modification in the initial shade of the raw timber gradually, which tends to end up being gray.
What Are the Consequences of Greying?
Greying or graying, which is a very superficial sensation, only affects the wooden framework’s aesthetic appeals. It does not indicate an architectural modification and does not impact the solidity of the material. The appearance of this phenomenon is limited to the surface of the wood. The loss of architectural sturdiness (which can go as far as the ruin of the product) is, for its part, as a result of strikes of biological origin that impact the wood in its mass.
Is it possible to prevent the greying of the wood without keeping it?
NO – Without ending up products as well as without upkeep, it would be imaginary to declare to be able to stop the timber from greying.
Will the application of a surface protect against the wood from turning grey?
YES – If this application is made consistently, it is possible to avoid this phenomenon. The hydrophobic nature of the oil strongly restricts the timber’s affinity for water as well as consequently delays its activity. Diy Photography Furniture
Remedied as well as Thermo-Oiled Timber
A number of current procedures have actually made it feasible to boost the sturdiness as well as dimensional stability of other types considerably: these are high-temperature warm therapies (210 to 250 ° C )in several stages, executed in special heaters, either under an inert atmosphere with nitrogen (remedied timber) or with water vapor injections (Finnish heat-treated lumber). The wood takes on a stunning brown shade and becomes hydrophobic as well as very immune to fungal or insect assaults. The high temperature level damages these timbers a little, which can not be made use of for architectural functions (primarily in home siding, parquet, and also balcony boards).
The so-called homeothermic process does not have this negative aspect: the wood is only warmed up to 130 ° C, with an immersion in a blend based on linseed oil and also vegetable oil by-products, which permits a deep impregnation. This also guarantees a much longer resistance to greying as well as does not require normal maintenance. The process creators have started to market it in France: three manufacturers in the timber sector have actually currently bought it, and also others are in the pipe. The current Wood-Protect process patented by Lapeyre as well as INRA-INPT in Toulouse is of the very same type, with impregnation by autoclave and afterwards by soaking at 140 ° C in a blend of grease derivatives and also acetic acid.

High-temperature therapies make the wood wholly waterproof as well as fungi resistant.
The wood is offered a temperature between 210 ° C and also 250 ° C in unique stoves. It then transforms shade to come to be darker. The main negative aspect is that it sheds its strength. It can after that just be used for cladding or flooring.
Oleothermy is a treatment that contains 3 stages: heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bathroom, as well as drying. Considering that the home heating temperature level is less than the previous method, the wood is much less brittle.
Studies have shown that homeothermic heating is useful when done after boron treatment. Boron has anti-inflammatory properties. The trouble is that it is not immune to cleaning. Therefore, the homeothermic makes it possible to fix the molecule and make the timber a lot more resistant to flames, water, as well as shocks. To get more information concerning this method, below is a doctoral thesis that was done on the topic.
Oils, Spots, and Paints
The durability of specific varieties such as oak and also chestnut is mostly as a result of their high tannin content. Nevertheless, these are gradually rinsed by rain, which is somewhat acidic. Like various other species, oak and chestnut, therefore, call for surface security. Linseed oil with a little turpentine included – to be used in heat (it permeates far better) – is classic and inexpensive security, water-repellent, as well as hold-ups greying.
Organic wood stains, which are tinted however reveal the wood grain, give far better security against UV rays thanks to the pigments they consist of. Nevertheless, they must be restored every 3 to 5 years for the south exteriors and also every 8 to ten years for the north exteriors. Unlike paints, they do not need sanding prior to renewal (a brush stroke is enough to remove the pigment dirt). As for organic lacquer paints, they supply even more sturdy protection since they contain fillers (particularly chalk) that create an entire display against UV rays. It’s a bit like sun creams; the security relies on the screen’s quality as well as the exposure. Diy Photography Furniture
Surface area Security
To improve the longevity of outdoor wood naturally, opt for a stain, for example, a blend of linseed oil as well as turpentine. Some readily available timber stains are colored and also offer slight UV defense. The advantage of this method is that no sanding is called for.
For even better protection, use organic lacquer paint. It will certainly offer optimal security versus ultraviolet rays– favor microporous paints including chalk fillers to allow the timber breathe.
Shielding exterior wood normally can be made with a safety tarnish or warm treatment. The choice of technique depends upon the characteristics that you wish to customize. If particular wood varieties can be used without protection, they have to be stained after a particular duration because the safety tannins will have gone away. If you do refrain this, you will need to have a professional moisture therapy.
Shielding Wood from Water
Shielding timber from water is a crucial function of an outside surface prior to any decorative aspect. It is recommended to save the product with paint, varnish, stain, saturator, or oil. Without a doubt, it is important to attain a real obstacle impact, which must be water resistant if the timber is not to weaken also promptly.
This makes it feasible to maintain all-natural, solid, raw, or veneered wood basically in time. It is safeguarded to maintain for years when faced with the different weather hostilities encountered. It is durably preserved from humidity, rainfall, bad climate, light, sun, as well as ultraviolet rays, making it age too soon. Diy Photography Furniture
Continue To Be Naturally Absorptive to Dampness
Remain moisture permeableStaying normally absorptive to smoke is very crucial. Wood is comprised of plant fibers that have an outstanding affinity with water. It is, as a result, a breakable material that remains easily absorptive to water. It continues to be particularly conscious numerous fluids that penetrate it.
Timber absorbs very rapidly the humidity that exists in the ambient environment. It soaks up water prior to normally launching it because it is a hygroscopic product. It continues to be in consistent balance with its atmosphere, whatever the moisture web content.
These different humidity variations are at the origin of the normal dimensional improvements of wood. They have the impact of triggering contortions that can occasionally be substantial. It works by swelling if the air is as well damp. It diminishes when the environment ends up being drier.
Rainfall, showers, thunderstorms, and other bad weather that are in contact with the timber can cause the appearance of unattractive spots, streaks, drips, as well as halos. Moisture, seepage, condensation, and water vapor are additionally in charge of the premature aging of wood throughout the years. Diy Photography Furniture
Do Not Avoid Exchanges with The Outside World.
Do not prevent exchanges with the outdoors not avoid interactions with the exterior; it should be respected. When you wish to protect the timber, a water-repellent product should be applied to avoid water from permeating it. It needs to be made sure that it is not impregnated by moisture if it is to last over the long term.
A timber therapy item can only be flawlessly appropriate if it values the various moisture exchanges. The timber needs to have the ability to continue to control itself with its environment. It is necessary to guarantee that the movie remains sufficiently micro-porous to assure a great exchange effectiveness.
On the other hand, impermeability as well as water rigidity must not be confused, which are extremely different ideas. Waterproofing must be restricted in the case of wood protection. Making a timber entirely watertight might trigger the product to rot in the long-term.
Gas exchange, which controls the wetness material in the timber’s pores, must never ever be prevented. A wood paint must allow the substrate to breathe without ever before quiting the inner emptying to the outside. It has to just avoid water from passing through the heart of the wood, not to modify or degrade it.
Choosing a Right Timber Treatment Product
Selecting a timber therapy selecting the best timber therapy product is vital to protect wood efficiently with time. There are various kinds of items that can properly maintaining this product. One can use an item that penetrates deeply, such as oil, impregnation, or saturator.
A passing through therapy supplies a lot more efficient protection than an item that transfers a movie on the surface, such as paint, varnish, or sealant, for instance. While a film-forming item may seem valuable originally, this is not constantly the instance in the lengthy term.
Indeed, they can wind up splitting, flaking, splitting, or peeling throughout the years. Seepage, water, or humidity permeates the material, which becomes inadequately insulated. It is after that essential to sand or strip the surface area of the wood to bare it once more to be preserved.
Silicones are widely made use of in timber waterproofing products. These hazardous materials should be stayed clear of similarly as oil solvents, which are still present in lots of products. They are not safe to the customer, the atmosphere, or nature. It is much better to choose a bio-sourced product of plant beginning that is consistent with this all-natural material.

Preserve Routinely for Adequate Defense.
Maintain forever protection preserve routinely for an appropriate defense, remains a procedure that must not be failed to remember to execute. Despite the type of waterproofing chosen to protect the timber, it is needed to maintain it consistently to make sure that the protection remains completely efficient over time.
Laborious prep work, fining sand, gritting, or removing of the surface can be prevented making use of an oil, saturator, or impregnation. They have the particularity of securing the product throughout its mass without developing a film externally that can flake off afterward.
A waterproofing representative’s function is to secure the timber from stains, marks, rings, as well as daily deterioration. It is generally related to an anti UV agent that will certainly stop the wood from becoming also grey over time. It thus restricts the phenomenon of swelling or contraction.
A non-film-forming water repellent has numerous advantages for preserving a wood surface area. It is very reliable against bad weather thanks to an obstacle result. Likewise, it continues to be very reliable in nurturing the timber in all its depth to the product’s actual heart. It also protects the assistance from light, sun, and ultraviolet rays.
