Outside timber has 2 main adversaries: UV (ultraviolet rays from sunlight) and moisture. The first causes a kind of surface melt – like on our skin, causing small cracks as well as greying. Absolutely nothing remarkable, the damages is generally visual, as well as the wood is not impacted in depth. Event Floor Plan Furniture Placement
Wetness presents much more serious issues: if rain does not run or does not vaporize swiftly, if the wood stays in contact with the ground or if the wetness can rise by capillary action, the moisture material of the timber will certainly allow the installment of lignivorous fungi that are forerunners to rot and favor strikes by wood-eating pests. Can chemical preservative treatments be avoided?
Durable Variety, without Sapwood
Some naturally long lasting species from our areas can be utilized without treatment when the timber is laid up and down (risk course 3) and also enables good water drain (cladding, home windows, shutters): specifically Douglas, larch, chestnut, oak, as well as cicada. Just the last 3 varieties are advised when the wood is laid horizontally (veranda or balcony boards) or in contact with the ground (threat course 4). These woods should also be chosen as well as cut in such a way regarding remove the sapwood, the peripheral part of the trunk rich in sugars, which draws in wood-eating pests.

What Are the Benefits of Securing Your Timber?
Embellishes and Secures
Past maintaining the aesthetic aspect in time, using a wood oil or a saturator in the defense of wood will revitalize its original color as well as boost the grain of the timber while maintaining its natural appearance.
Stabilizes the Timber
Fueling oil a wood allows enhancing its dimensional stability durably, thus minimizing the phenomena of deformation (tiling, swelling, and shrinking), breaking, or surface area splitting.
All-natural and Ecological
Choosing an “Oleobois” protective oil indicates picking a healthy and eco-friendly remedy; the composition leaves out fungicides, turpentine, and also any oil derivatives often utilized (paraffin, white spirit, …).
Easy as well as Economical Maintenance
Upkeep is easy due to the fact that when fueled oil; wood does not require to be stripped or fined sand prior to improvement: a cleaning with black soap followed by a basic re-oiled surface suffices. Event Floor Plan Furniture Placement
Greying of The Wood
What Is Wood Graying?
Wood is a material almost composed of polysaccharides (cellulose and hemicelluloses) as well as lignins that will be broken down under ultraviolet photons’ activity. This photodegradation of the lignins, which is also accentuated in the existence of water, is in charge of the evolution of the color of the timber. Greying is observed on the hardwood utilized outdoors with no physical protection and UV protection. This phenomenon triggers a change in the initial shade of the raw timber over time, which tends to end up being gray.
What Are the Repercussions of Greying?
Greying or graying, which is an extremely shallow phenomenon, just influences the wood framework’s aesthetics. It does not indicate a structural alteration and also does not affect the strength of the material. The look of this sensation is limited to the surface area of the timber. The loss of structural resilience (which can reach the spoil of the material) is, for its part, due to assaults of organic beginning that affect the wood in its mass.
Is it feasible to stay clear of the greying of the timber without keeping it?
NO – Without ending up products and without maintenance, it would certainly be imaginary to assert to be able to avoid the timber from greying.
Will the application of a finish prevent the wood from transforming gray?
YES – If this application is made regularly, it is feasible to avoid this phenomenon. The hydrophobic nature of the oil highly restricts the timber’s affinity for water and for that reason postpones its activity. Event Floor Plan Furniture Placement
Corrected and also Thermo-Oiled Wood
Numerous recent processes have made it feasible to boost the durability and also dimensional security of other varieties substantially: these are high-temperature heat treatments (210 to 250 ° C )in a number of stages, carried out in special heaters, either under an inert atmosphere with nitrogen (fixed timber) or with water vapor injections (Finnish heat-treated lumber). The timber takes on a lovely brown color as well as ends up being hydrophobic as well as very resistant to fungal or insect attacks. The high temperature weakens these timbers a little, which can not be used for architectural functions (primarily in siding, parquet, and balcony boards).
The supposed homeothermic procedure does not have this disadvantage: the wood is only warmed up to 130 ° C, with an immersion in a mixture based upon linseed oil and also grease by-products, which enables a deep impregnation. This additionally guarantees a longer resistance to greying and does not require regular upkeep. The process makers have started to market it in France: 3 producers in the timber sector have actually currently bought it, and also others remain in the pipeline. The recent Wood-Protect process patented by Lapeyre and also INRA-INPT in Toulouse is of the very same type, with impregnation by autoclave and afterwards 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 waterproof and fungi immune.
The timber is brought to a temperature in between 210 ° C as well as 250 ° C in unique stoves. It then transforms shade to become darker. The main negative aspect is that it loses its stamina. It can after that only be utilized for cladding or flooring.
Oleothermy is a therapy that contains 3 phases: heating to 130 ° C in a rapeseed oil bathroom, cooling in a linseed oil bath, as well as drying out. Since the heating temperature level is lower than the previous method, the wood is less brittle.
Researches have actually revealed that homeothermic heating is helpful when done after boron therapy. Boron has anti-inflammatory buildings. The issue is that it is not immune to washing. Therefore, the homeothermic makes it feasible to take care of the particle and also make the wood extra resistant to flames, water, and also shocks. For more information concerning this approach, below is a doctoral thesis that was done on the topic.
Oils, Spots, and also Paints
The sturdiness of certain types such as oak and also chestnut is mostly as a result of their high tannin web content. Nonetheless, these are gradually washed out by rainwater, which is a little acidic. Like other varieties, oak and also chestnut, for that reason, require surface protection. Linseed oil with a little turpentine added – to be made use of in hot weather (it permeates much better) – is timeless and also affordable security, water-repellent, and also hold-ups greying.
Organic wood spots, which are tinted however show the wood grain, offer far better defense versus UV rays thanks to the pigments they have. They should be renewed every 3 to 5 years for the south exteriors and every 8 to 10 years for the north facades. Unlike paints, they do not call for sanding before revival (a brush stroke is enough to remove the pigment dust). As for organic lacquer paints, they offer more long lasting defense because they include fillers (especially chalk) that create an entire screen versus UV rays. It’s a bit like sun creams; the safety and security relies on the display’s high quality and the exposure. Event Floor Plan Furniture Placement
Surface area Defense
To boost the durability of outside timber naturally, go with a stain, as an example, a mixture of linseed oil and also turpentine. Some commercially available wood stains are tinted as well as offer minor UV defense. The benefit of this approach is that no sanding is called for.
For even far better protection, apply organic lacquer paint. It will provide ideal protection against ultraviolet rays– favor microporous paints including chalk fillers to allow the wood take a breath.
Shielding outside timber normally can be done with a safety stain or warmth therapy. The option of technique relies on the characteristics that you want to modify. If particular wood species can be used without defense, they have to be stained after a particular duration because the protective tannins will have disappeared. If you do not do this, you will need to have a professional wetness treatment.
Safeguarding Wood from Water
Securing timber from water is an essential function of an outside surface prior to any type of ornamental element. It is suggested to conserve the product with paint, varnish, stain, saturator, or oil. Certainly, it is necessary to attain an actual barrier effect, which need to be water resistant if the timber is not to weaken as well swiftly.
This makes it possible to maintain natural, strong, raw, or veneered timber practically in time. It is protected to keep for many years in the face of the different weather hostilities encountered. It is durably maintained from humidity, rainfall, negative weather condition, light, sunlight, and ultraviolet rays, making it age prematurely. Event Floor Plan Furniture Placement
Stay Normally Absorptive to Wetness
Remain moisture permeableStaying normally absorptive to smoke is really essential. Timber is comprised of plant fibers that have an excellent affinity with water. It is, therefore, a fragile product that continues to be easily absorptive to water. It remains especially sensitive to numerous fluids that permeate it.
Timber absorbs extremely swiftly the humidity that is present in the ambient atmosphere. It absorbs water prior to naturally releasing it since it is a hygroscopic material. It remains in constant balance with its setting, whatever the wetness material.
These various moisture variations are at the beginning of the normal dimensional improvements of timber. They have the impact of triggering deformations that can sometimes be significant. It works by swelling if the air is too damp. It reduces when the ambience becomes drier.
Rainfall, showers, thunderstorms, and also other poor weather that are in contact with the wood can cause the appearance of unsightly spots, streaks, trickles, and also halos. Dampness, seepage, condensation, and water vapor are also in charge of the early aging of wood throughout the years. Event Floor Plan Furniture Placement
Do Not Avoid Exchanges with The Outdoors.
Do not prevent exchanges with the outside not prevent communications with the outside; it should be appreciated. When you wish to protect the wood, a water-repellent product has to be applied to avoid water from penetrating it. It has to be ensured that it is not impregnated by moisture if it is to last over the long-term.
A wood treatment item can only be completely ideal if it appreciates the different wetness exchanges. The wood needs to be able to continue to manage itself with its environment. It is essential to guarantee that the film stays completely micro-porous to guarantee an excellent exchange efficiency.
On the other hand, impermeability and water rigidity must not be perplexed, which are very different ideas. Waterproofing should be forbidden when it comes to timber security. Making a timber totally watertight may trigger the material to rot in the long-term.
Gas exchange, which regulates the dampness content in the timber’s pores, should never be protected against. A timber paint have to permit the substrate to breathe without ever before quiting the interior discharge to the outside. It must simply protect against water from permeating the heart of the wood, not to change or degrade it.
Picking a Right Timber Treatment Product
Selecting a timber treatment picking the right timber therapy item is essential to safeguard timber effectively gradually. There are different types of items that are capable of efficiently preserving this material. One can make use of a product that penetrates deeply, such as oil, impregnation, or saturator.
A penetrating therapy offers more efficient security than a product that deposits a movie on the surface area, such as paint, varnish, or sealer. Indeed, while a film-forming product might appear valuable at first, this is not always the situation in the long term.
Without a doubt, they can end up splitting, flaking, cracking, or peeling for many years. Infiltration, water, or moisture permeates the material, which ends up being improperly shielded. It is after that necessary to sand or strip the surface area of the timber to bare it once again to be preserved.
Silicones are widely used in timber waterproofing items. These unsafe materials need to be prevented in the same way as oil solvents, which are still existing in several items. They are not harmless to the user, the environment, or nature. It is better to select a bio-sourced product of plant beginning that follows this natural product. Event Floor Plan Furniture Placement
Maintain Frequently for Adequate Security.
Keep for good security preserve routinely for a sufficient protection, stays an operation that should not be neglected to do. No matter the kind of waterproofing picked to maintain the wood, it is necessary to preserve it frequently to ensure that the protection stays adequately reliable gradually.
Laborious prep work, sanding, gritting, or stripping of the surface can be prevented utilizing an oil, saturator, or impregnation. They have the particularity of safeguarding the material throughout its mass without producing a film externally that can flake off afterward.
A waterproofing representative’s feature is to secure the wood from spots, marks, rings, and day-to-day damage. It is generally connected with an anti UV representative that will certainly prevent the wood from becoming too grey over time. It therefore limits the phenomenon of swelling or shrinking.
A non-film-forming water repellent has many benefits for protecting a wood surface. It is extremely effective versus poor climate thanks to an obstacle result. Likewise, it remains really reliable in nurturing the timber in all its deepness to the product’s actual heart. It likewise secures the assistance from light, sun, and ultraviolet rays.
