Outside timber has two main enemies: UV (ultraviolet rays from sunlight) as well as humidity. The first causes a sort of superficial burn – like on our skin, resulting in tiny fractures and also greying. Nothing remarkable, the damage is mostly aesthetic, as well as the timber is not influenced in depth. G Plan Furniture History
Moisture positions much more severe problems: if rainwater does not run or does not vaporize rapidly, if the timber stays touching the ground or if the dampness can rise by capillary action, the dampness material of the wood will enable the installment of lignivorous fungis that are forerunners to rot and support assaults by wood-eating insects. Can chemical preservative treatments be avoided?
Sturdy Variety, without Sapwood
Some naturally long lasting species from our regions can be made use of without treatment when the wood is laid vertically (threat class 3) as well as permits great water drainage (cladding, windows, shutters): particularly Douglas, larch, chestnut, oak, as well as cicada. Just the last three types are recommended when the wood is laid flat (veranda or balcony boards) or touching the ground (danger course 4). These timbers have to also be chosen and also cut in such a method as to eliminate the sapwood, the peripheral part of the trunk abundant in sugars, which attracts wood-eating pests.

What Are the Advantages of Securing Your Timber?
Embellishes as well as Secures
Beyond keeping the aesthetic aspect in time, using a wood oil or a saturator in the protection of timber will certainly restore its original color as well as boost the grain of the wood while keeping its natural look.
Stabilizes the Timber
Oiling a timber permits improving its dimensional security durably, hence lowering the sensations of deformation (tiling, swelling, as well as shrinking), fracturing, or surface splitting.
All-natural as well as Ecological
Choosing an “Oleobois” protective oil suggests selecting a healthy and balanced as well as environmentally friendly option; the structure leaves out fungicides, turpentine, and also any petroleum by-products regularly utilized (paraffin, white spirit, …).
Easy as well as Economical Maintenance
Maintenance is very easy due to the fact that as soon as oiled; timber does not require to be removed or sanded prior to remodelling: a cleansing with black soap complied with by an easy re-oiled surface area is enough. G Plan Furniture History
Greying of The Timber
What Is Wood Graying?
Timber is a material virtually made up of polysaccharides (cellulose and also hemicelluloses) as well as lignins that will be weakened under ultraviolet photons’ activity. This photodegradation of the lignins, which is likewise highlighted in the visibility of water, is accountable for the evolution of the color of the timber. Greying is observed on the timber made use of outdoors without any physical defense as well as UV security. This phenomenon triggers a change in the initial shade of the raw timber in time, which tends to come to be grey.
What Are the Effects of Greying?
Greying or graying, which is a really surface sensation, just affects the wooden structure’s looks. It does not show a structural alteration and does not affect the solidity of the material. The look of this sensation is limited to the surface of the timber. The loss of structural durability (which can go as far as the destroy of the material) is, for its part, as a result of assaults of organic beginning that impact the timber in its mass.
Is it possible to stay clear of the greying of the timber without preserving it?
NO – Without ending up items and without upkeep, it would be illusory to declare to be able to prevent the wood from greying.
Will the application of a surface stop the timber from turning gray?
YES – If this application is made frequently, it is feasible to avoid this sensation. The hydrophobic nature of the oil highly restricts the timber’s fondness for water and consequently postpones its activity. G Plan Furniture History
Fixed as well as Thermo-Oiled Timber
Numerous recent procedures have made it feasible to improve the toughness as well as dimensional stability of other types significantly: these are high-temperature heat treatments (210 to 250 ° C )in a number of phases, executed in unique furnaces, either under an inert environment with nitrogen (fixed timber) or with water vapor shots (Finnish heat-treated lumber). The timber tackles an attractive brownish color and becomes hydrophobic as well as very immune to fungal or insect strikes. The high temperature level compromises these timbers a little, which can not be utilized for structural purposes (primarily in house siding, parquet, and balcony boards).
The so-called homeothermic process does not have this negative aspect: the timber is only heated up to 130 ° C, with an immersion in a combination based on linseed oil and grease derivatives, which enables a deep impregnation. This also guarantees a longer resistance to greying as well as does not call for regular upkeep. The procedure developers have begun to market it in France: 3 suppliers in the timber sector have already bought it, as well as others are in the pipe. The current Wood-Protect procedure patented by Lapeyre and also 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 vegetable oil derivatives and also acetic acid.

High-temperature treatments make the timber wholly water resistant and also fungus immune.
The timber is given a temperature level in between 210 ° C as well as 250 ° C in special ovens. It then alters color to come to be darker. The primary drawback is that it loses its stamina. It can then just be utilized for cladding or floor covering.
Oleothermy is a treatment that includes 3 stages: heating to 130 ° C in a rapeseed oil bath, cooling in a linseed oil bathroom, as well as drying out. Given that the heating temperature is less than the previous approach, the wood is much less fragile.
Research studies have revealed that homeothermic heating is helpful when done after boron treatment. Boron has anti-inflammatory homes. The trouble is that it is not immune to cleaning. Thus, the homeothermic makes it possible to deal with the particle and make the wood more resistant to flames, water, and also shocks. For more information concerning this method, here is a doctoral thesis that was done on the subject.
Oils, Spots, and also Paints
The longevity of particular types such as oak as well as chestnut is generally due to their high tannin material. Nonetheless, these are slowly rinsed by rainwater, which is slightly acidic. Like various other varieties, oak as well as chestnut, consequently, require surface area defense. Linseed oil with a little turpentine added – to be made use of in hot weather (it passes through better) – is timeless and economical security, water-repellent, and hold-ups greying.
Organic wood stains, which are colored however show the timber grain, provide far better protection versus UV rays thanks to the pigments they include. They ought to be renewed every 3 to 5 years for the south facades and also every 8 to 10 years for the north exteriors. Unlike paints, they do not need sanding prior to renewal (a brush stroke suffices to remove the pigment dust). As for natural lacquer paints, they offer more long lasting defense because they include fillers (especially chalk) that form a whole display versus UV rays. It’s a bit like sun creams; the security depends upon the screen’s top quality and also the exposure. G Plan Furniture History
Surface area Protection
To improve the durability of outside wood normally, go with a discolor, for example, a mixture of linseed oil as well as turpentine. Some readily available timber spots are colored and supply minor UV defense. The advantage of this approach is that no sanding is needed.
For even better defense, use organic lacquer paint. It will provide ideal defense versus ultraviolet rays– favor microporous paints having chalk fillers to let the wood breathe.
Securing outside timber normally can be made with a protective tarnish or heat treatment. The option of method depends upon the features that you want to modify. If specific wood types can be used without security, they must be tarnished after a particular duration since the protective tannins will certainly have gone away. If you do refrain from doing this, you will have to have an expert dampness therapy.
Protecting Wood from Water
Securing timber from water is an essential feature of an outside finish prior to any attractive facet. It is advised to save the product with paint, varnish, stain, saturator, or oil. Without a doubt, it is important to achieve an actual obstacle result, which need to be waterproof if the timber is not to degrade also quickly.
This makes it possible to maintain all-natural, solid, raw, or veneered wood basically gradually. It is protected to maintain for many years in the face of the numerous climatic aggressiveness encountered. It is durably preserved from moisture, rain, bad climate, light, sunlight, and also ultraviolet rays, making it age prematurely. G Plan Furniture History
Stay Normally Permeable to Dampness
Stay moisture permeableStaying naturally permeable to smoke is really essential. Wood is composed of plant fibers that have a superb fondness with water. It is, as a result, a fragile material that stays easily absorptive to water. It continues to be specifically conscious different liquids that permeate it.
Wood soaks up very quickly the humidity that exists in the ambient environment. It takes in water prior to normally launching it because it is a hygroscopic product. It stays in consistent balance with its setting, whatever the moisture material.
These various moisture variants are at the beginning of the usual dimensional transformations of timber. They have the result of creating contortions that can sometimes be significant. It works by swelling if the air is also humid. It diminishes when the ambience comes to be drier.
Rainfall, showers, electrical storms, as well as various other bad weather that touch with the wood can trigger the look of undesirable spots, streaks, leaks, and also halos. Moisture, seepage, condensation, and water vapor are additionally in charge of the early aging of timber for many years. G Plan Furniture History
Do Not Stop Exchanges with The Outside World.
Do not avoid exchanges with the outside not prevent communications with the outside; it must be appreciated. When you intend to safeguard the wood, a water-repellent product should be put on avoid water from penetrating it. It should be guaranteed that it is not impregnated by dampness if it is to last over the long term.
A timber therapy product can just be flawlessly ideal if it respects the different dampness exchanges. The timber should be able to remain to manage itself with its setting. It is important to make certain that the movie stays sufficiently micro-porous to assure a great exchange effectiveness.
On the other hand, impermeability and water tightness need to not be confused, which are very various notions. Waterproofing must be forbidden in the case of wood protection. Making a wood totally watertight might cause the product to rot in the long-term.
Gas exchange, which regulates the dampness content in the timber’s pores, need to never ever be protected against. A timber paint should permit the substrate to take a breath without ever before stopping the inner evacuation to the outside. It should simply protect against water from permeating the heart of the wood, not to alter or weaken it.
Choosing a Right Timber Treatment Item
Selecting a wood therapy choosing the best timber treatment item is necessary to secure timber successfully with time. There are different types of items that are capable of successfully preserving this product. One can make use of a product that passes through deeply, such as oil, impregnation, or saturator.
A passing through therapy provides extra effective defense than a product that deposits a film on the surface, such as paint, varnish, or sealer, as an example. While a film-forming product might seem useful at first, this is not constantly the instance in the lengthy term.
Without a doubt, they can wind up fracturing, flaking, splitting, or removing throughout the years. Infiltration, water, or humidity penetrates the material, which ends up being poorly shielded. It is after that necessary to sand or strip the surface of the timber to bare it once again to be maintained.
Silicones are commonly used in wood waterproofing items. These unsafe materials need to be prevented in the same way as oil solvents, which are still existing in several products. They are not safe to the customer, the setting, or nature. It is better to select a bio-sourced item of plant beginning that follows this all-natural material. G Plan Furniture History
Maintain Frequently for Adequate Security.
Keep for good defense keep consistently for an appropriate protection, continues to be an operation that must not be neglected to do. Despite the kind of waterproofing chosen to protect the wood, it is necessary to keep it on a regular basis to ensure that the protection remains completely effective over time.
Tedious preparation, fining sand, gritting, or stripping of the surface area can be prevented making use of an oil, saturator, or impregnation. They have the particularity of securing the product throughout its mass without producing a film externally that can exfoliate later.
A waterproofing representative’s feature is to secure the wood from stains, marks, rings, and also day-to-day damage. It is typically associated with an anti UV representative that will stop the wood from ending up being too grey in the long run. It thus restricts the sensation of swelling or shrinking.
A non-film-forming water repellent has many benefits for protecting a wooden surface. It is extremely effective against negative climate thanks to an obstacle result. Also, it remains very reliable in nourishing the timber in all its deepness to the product’s very heart. It additionally safeguards the support from light, sun, and also ultraviolet rays.
