Exterior timber has two main enemies: UV (ultraviolet rays from sunshine) as well as humidity. The first causes a sort of superficial melt – like on our skin, leading to little cracks as well as greying. Absolutely nothing dramatic, the damage is mostly visual, and the wood is not impacted detailed. Diy Furniture Risee
Moisture presents far more severe issues: if rainwater does not escape or does not evaporate rapidly, if the timber remains in contact with the ground or if the wetness can rise by capillary activity, the dampness web content of the timber will certainly allow the installation of lignivorous fungi that are precursors to rot and also favor assaults by wood-eating insects. Can chemical preservative treatments be avoided?
Resilient Species, without Sapwood
Some naturally long lasting types from our areas can be utilized without therapy when the wood is laid vertically (danger class 3) and also enables excellent water drainage (cladding, home windows, shutters): particularly Douglas, larch, chestnut, oak, as well as locust. Just the last 3 types are suggested when the timber is laid horizontally (veranda or terrace boards) or in contact with the ground (risk course 4). These timbers need to also be picked as well as cut in such a means regarding remove the sapwood, the outer part of the trunk rich in sugars, which brings in wood-eating insects. Diy Furniture Risee
What Are the Benefits of Securing Your Timber?
Embellishes as well as Secures
Past maintaining the aesthetic aspect in time, utilizing a timber oil or a saturator in the defense of wood will certainly revitalize its initial color and boost the grain of the timber while keeping its natural appearance.
Supports the Timber
Fueling oil a timber permits improving its dimensional security durably, hence decreasing the phenomena of contortion (tiling, swelling, and also shrinkage), fracturing, or surface area splitting.
All-natural and also Ecological
Selecting an “Oleobois” protective oil implies choosing a healthy and balanced and also eco-friendly option; the make-up omits fungicides, turpentine, and any kind of oil by-products regularly utilized (paraffin, white spirit, …).
Easy and also Economical Upkeep
Upkeep is simple since as soon as oiled; wood does not need to be stripped or fined sand before improvement: a cleansing with black soap adhered to by a simple re-oiled surface area is enough. Diy Furniture Risee
Greying of The Wood
What Is Wood Graying?
Timber is a product almost composed of polysaccharides (cellulose and also hemicelluloses) and lignins that will certainly be deteriorated under ultraviolet photons’ activity. This photodegradation of the lignins, which is likewise accentuated in the visibility of water, is in charge of the evolution of the color of the timber. Greying is observed on the hardwood made use of outdoors with no physical defense and UV security. This sensation creates a modification in the original color of the raw timber in time, which tends to become gray.
What Are the Effects of Greying?
Greying or graying, which is a really superficial sensation, just impacts the wood structure’s aesthetics. It does not suggest an architectural change and also does not affect the solidity of the product. The look of this sensation is restricted to the surface area of the wood. The loss of architectural toughness (which can go as far as the spoil of the material) is, for its component, as a result of assaults of organic beginning that impact the wood in its mass.
Is it possible to avoid the greying of the wood without preserving it?
NO – Without completing items as well as without maintenance, it would certainly be imaginary to claim to be able to stop the wood from greying.
Will the application of a surface avoid the timber from turning grey?
YES – If this application is made frequently, it is possible to prevent this phenomenon. The hydrophobic nature of the oil strongly limits the wood’s fondness for water and consequently delays its activity. Diy Furniture Risee
Corrected and also Thermo-Oiled Wood
A number of recent procedures have made it feasible to enhance the durability and dimensional security of other varieties dramatically: these are high-temperature heat treatments (210 to 250 ° C )in several stages, carried out in unique heating systems, either under an inert environment with nitrogen (fixed timber) or with water vapor injections (Finnish heat-treated lumber). The wood tackles a gorgeous brownish shade as well as ends up being hydrophobic and extremely immune to fungal or insect assaults. The high temperature level damages these woods a little, which can not be used for architectural objectives (mostly in home siding, parquet, and terrace boards).
The supposed homeothermic procedure does not have this disadvantage: the timber is just heated up to 130 ° C, with an immersion in a mixture based upon linseed oil and vegetable oil derivatives, which permits a deep impregnation. This likewise makes sure a longer resistance to greying and does not call for routine maintenance. The procedure creators have begun to market it in France: three makers in the timber market have actually already bought it, and others remain in the pipe. The recent Wood-Protect procedure patented by Lapeyre and also INRA-INPT in Toulouse is of the same kind, with impregnation by autoclave and afterwards by saturating at 140 ° C in a mix of vegetable oil by-products and acetic acid.

High-temperature treatments make the wood wholly water-proof and also fungi resistant.
The timber is brought to a temperature between 210 ° C and 250 ° C in unique ovens. It then changes shade to become darker. The main disadvantage is that it loses its stamina. It can then only be utilized for cladding or floor covering.
Oleothermy is a treatment that contains 3 phases: heating to 130 ° C in a rapeseed oil bath, cooling down in a linseed oil bath, and also drying out. Considering that the heating temperature level is less than the previous method, the wood is less weak.
Research studies have actually revealed that homeothermic home heating is useful when done after boron therapy. Boron has anti-inflammatory residential or commercial properties. The issue is that it is not immune to cleaning. Hence, the homeothermic makes it possible to deal with the molecule as well as make the wood a lot more immune to fires, water, as well as shocks. To find out more regarding this method, below is a doctoral thesis that was done on the subject.
Oils, Discolorations, as well as Paints
The sturdiness of certain varieties such as oak and chestnut is primarily because of their high tannin material. Nonetheless, these are gradually washed out by rain, which is slightly acidic. Like various other varieties, oak as well as chestnut, consequently, require surface area protection. Linseed oil with a little turpentine added – to be used in heat (it penetrates much better) – is timeless and economical protection, water-repellent, and also hold-ups greying.
Organic timber discolorations, which are colored but show the timber grain, supply much better protection versus UV rays thanks to the pigments they have. They ought to be renewed every 3 to 5 years for the south exteriors and also every 8 to 10 years for the north facades. Unlike paints, they do not require sanding before revival (a brush stroke suffices to eliminate the pigment dust). As for natural lacquer paints, they provide more durable protection because they have fillers (particularly chalk) that create a whole display versus UV rays. It’s a bit like sun creams; the safety and security depends on the screen’s top quality as well as the exposure. Diy Furniture Risee
To enhance the resilience of exterior timber naturally, choose a discolor, for instance, a blend of linseed oil as well as turpentine. Some commercially readily available timber discolorations are colored and give minor UV defense. The benefit of this method is that no sanding is required.
For also better defense, apply natural lacquer paint. It will certainly provide ideal defense versus ultraviolet rays– favor microporous paints consisting of chalk fillers to allow the timber take a breath.
Shielding external wood naturally can be made with a safety tarnish or warm treatment. The option of method depends on the qualities that you desire to modify. If particular wood varieties can be used without security, they must be stained after a specific duration due to the fact that the protective tannins will have gone away. If you do refrain this, you will have to have an expert wetness therapy.
Securing Timber from Water
Safeguarding timber from water is a vital function of an outside surface prior to any ornamental facet. It is recommended to save the product with paint, varnish, tarnish, saturator, or oil. Without a doubt, it is important to attain a real barrier result, which need to be water resistant if the wood is not to wear away also rapidly.
This makes it possible to preserve all-natural, solid, raw, or veneered wood virtually with time. It is safeguarded to maintain for many years in the face of the different weather aggressions ran into. It is durably preserved from humidity, rainfall, poor climate, light, sun, and ultraviolet rays, making it age too soon. Diy Furniture Risee
Stay Naturally Absorptive to Dampness
Remain moisture permeableStaying naturally permeable to smoke is really vital. Timber is composed of plant fibers that have a superb affinity with water. It is, as a result, a vulnerable product that remains easily absorptive to water. It stays especially conscious numerous fluids that penetrate it.
Wood soaks up extremely rapidly the moisture that exists in the ambient environment. It absorbs water prior to naturally launching it due to the fact that it is a hygroscopic product. It remains in continuous equilibrium with its atmosphere, whatever the wetness material.
These different humidity variants are at the beginning of the typical dimensional changes of wood. They have the effect of triggering contortions that can sometimes be considerable. It works by swelling if the air is also humid. It diminishes when the ambience becomes drier.
Rainfall, showers, thunderstorms, and various other poor weather condition that touch with the timber can trigger the look of unattractive spots, streaks, trickles, as well as halos. Moisture, infiltration, condensation, as well as water vapor are likewise in charge of the premature aging of timber for many years. Diy Furniture Risee
Do Not Prevent Exchanges with The Outdoors.
Do not stop exchanges with the outside not protect against interactions with the exterior; it has to be respected. When you intend to secure the timber, a water-repellent product should be related to prevent water from permeating it. It needs to be guaranteed that it is not impregnated by wetness if it is to last over the long-term.
A wood therapy product can just be flawlessly suitable if it appreciates the various dampness exchanges. The wood must be able to remain to regulate itself with its atmosphere. It is necessary to make certain that the film stays completely micro-porous to assure a good exchange effectiveness.
On the other hand, impermeability and also water tightness ought to not be puzzled, which are very various ideas. Waterproofing should be restricted when it comes to timber security. Making a timber completely watertight might create the product to rot in the long term.
Gas exchange, which manages the moisture material in the timber’s pores, should never be prevented. A wood paint must allow the substratum to breathe without ever stopping the internal evacuation to the exterior. It has to just stop water from permeating the heart of the timber, not to change or deteriorate it.
Selecting a Right Wood Treatment Item
Selecting a wood treatment selecting the right timber treatment product is essential to safeguard wood successfully in time. There are various sorts of items that are capable of properly maintaining this material. One can make use of an item that permeates deeply, such as oil, impregnation, or saturator.
A permeating treatment gives more reliable protection than an item that transfers a film externally, such as paint, varnish, or sealant, for example. Indeed, while a film-forming product might seem valuable initially, this is not constantly the instance in the long-term.
Certainly, they can wind up cracking, flaking, breaking, or removing throughout the years. Seepage, water, or humidity permeates the material, which becomes inadequately insulated. It is then necessary to sand or strip the surface of the wood to bare it again to be protected.
Silicones are commonly utilized in wood waterproofing products. These unsafe materials need to be prevented similarly as petroleum solvents, which are still existing in lots of items. They are not harmless to the customer, the environment, or nature. It is far better to choose a bio-sourced product of plant beginning that is consistent with this all-natural material.

Preserve Routinely for Adequate Protection.
Preserve for good security preserve frequently for a sufficient protection, continues to be an operation that must not be failed to remember to perform. Regardless of the sort of waterproofing selected to maintain the timber, it is essential to preserve it on a regular basis so that the security continues to be sufficiently effective with time.
Tedious preparation, fining sand, gritting, or removing of the surface area can be prevented using an oil, saturator, or impregnation. They have the particularity of securing the material throughout its mass without creating a film externally that can flake off later.
A waterproofing representative’s feature is to secure the timber from stains, marks, rings, and also day-to-day deterioration. It is generally connected with an anti UV representative that will certainly protect against the timber from becoming too grey in the long run. It thus restricts the phenomenon of swelling or shrinking.
A non-film-forming water repellent has many advantages for protecting a wooden surface area. It is extremely effective against negative weather condition thanks to an obstacle result. Also, it stays extremely reliable in nourishing the timber in all its deepness to the material’s very heart. It also protects the assistance from light, sun, and also ultraviolet rays.
