Exterior wood has two primary opponents: UV (ultraviolet rays from sunshine) and moisture. The first causes a type of surface melt – like on our skin, leading to tiny fractures and greying. Absolutely nothing dramatic, the damage is mainly aesthetic, as well as the wood is not affected detailed. Drafting Furniture Plan
Wetness presents far more severe troubles: if rain does not run off or does not evaporate quickly, if the timber remains touching the ground or if the moisture can increase by capillary action, the wetness content of the wood will permit the installment of lignivorous fungis that are precursors to rot and support assaults by wood-eating insects. Can chemical preservative treatments be prevented?
Long lasting Species, without Sapwood
Some normally durable species from our regions can be utilized without treatment when the wood is laid vertically (danger course 3) as well as allows great water drainage (cladding, home windows, shutters): in particular Douglas, larch, chestnut, oak, and also grasshopper. Just the last 3 varieties are suggested when the wood is laid flat (porch or terrace boards) or in contact with the ground (threat class 4). These woods have to also be picked as well as cut in such a means as to get rid of the sapwood, the peripheral part of the trunk abundant in sugars, which draws in wood-eating insects.

What Are the Advantages of Shielding Your Timber?
Embellishes and also Safeguards
Beyond preserving the aesthetic element gradually, using a timber oil or a saturator in the defense of wood will revive its original color and also enhance the grain of the wood while maintaining its natural look.
Stabilizes the Wood
Oiling a timber enables enhancing its dimensional security durably, therefore minimizing the phenomena of deformation (tiling, swelling, as well as shrinking), breaking, or surface splitting.
All-natural and Ecological
Picking an “Oleobois” safety oil indicates picking a healthy and balanced as well as eco-friendly option; the composition omits fungicides, turpentine, as well as any kind of petroleum derivatives often used (paraffin, white spirit, …).
Easy and also Economical Maintenance
Maintenance is easy because once oiled; wood does not require to be removed or fined sand prior to renovation: a cleaning with black soap adhered to by a basic re-oiled surface is enough. Drafting Furniture Plan
Greying of The Wood
What Is Wood Graying?
Wood is a product nearly composed of polysaccharides (cellulose and hemicelluloses) as well as lignins that will certainly be weakened under ultraviolet photons’ activity. This photodegradation of the lignins, which is likewise emphasized in the presence of water, is accountable for the advancement of the color of the wood. Greying is observed on the timber made use of outdoors with no physical defense and also UV security. This phenomenon causes an adjustment in the initial color of the raw timber gradually, which often tends to become grey.
What Are the Repercussions of Greying?
Greying or graying, which is an extremely shallow phenomenon, just influences the wooden structure’s appearances. It does not suggest an architectural modification and also does not affect the solidity of the material. The appearance of this sensation is limited to the surface of the timber. The loss of architectural durability (which can go as far as the wreck of the material) is, for its part, as a result of assaults 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 ending up products and also without upkeep, it would certainly be illusory to claim to be able to prevent the wood from greying.
Will the application of a finish protect against the timber from turning grey?
YES – If this application is made on a regular basis, it is possible to avoid this phenomenon. The hydrophobic nature of the oil highly limits the wood’s fondness for water and for that reason postpones its action. Drafting Furniture Plan
Rectified and also Thermo-Oiled Wood
Numerous recent procedures have actually made it feasible to improve the longevity and dimensional security of other species substantially: these are high-temperature warmth treatments (210 to 250 ° C )in a number of phases, carried out in special furnaces, either under an inert environment with nitrogen (remedied timber) or with water vapor shots (Finnish heat-treated lumber). The wood handles a lovely brownish color and also ends up being hydrophobic and really immune to fungal or insect attacks. The high temperature deteriorates these timbers a little, which can not be used for architectural objectives (mostly in siding, parquet, and terrace boards).
The supposed homeothermic procedure does not have this negative aspect: the wood is only warmed up to 130 ° C, with an immersion in a mixture based on linseed oil and also vegetable oil derivatives, which allows a deep impregnation. This likewise guarantees a much longer resistance to greying and also does not need regular maintenance. The process makers have actually begun to market it in France: three suppliers in the timber sector have actually already bought it, and also others are in the pipe. The recent Wood-Protect process patented by Lapeyre and INRA-INPT in Toulouse is of the exact same type, with impregnation by autoclave and then by soaking at 140 ° C in a mixture of vegetable oil by-products and acetic acid.

High-temperature therapies make the timber wholly water resistant and fungi resistant.
The wood is offered a temperature between 210 ° C and also 250 ° C in unique ovens. It after that transforms shade to end up being darker. The primary downside is that it sheds its strength. It can after that just 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, as well as drying out. Considering that the heating temperature level is lower than the previous technique, the timber is much less fragile.
Researches have shown that homeothermic home heating is useful when done after boron treatment. Boron has anti-inflammatory residential properties. The issue is that it is not resistant to washing. Thus, the homeothermic makes it feasible to fix the particle and make the timber much more resistant to fires, water, as well as shocks. For more information regarding this approach, here is a doctoral thesis that was done on the subject.
Oils, Discolorations, and also Paints
The resilience of specific species such as oak and also chestnut is generally due to their high tannin web content. Nevertheless, these are gradually rinsed by rainwater, which is a little acidic. Like other types, oak and chestnut, as a result, call for surface defense. Linseed oil with a little turpentine added – to be utilized in heat (it penetrates better) – is traditional and also low-cost security, water-repellent, as well as delays greying.
Organic wood stains, which are colored but reveal the wood grain, provide much better protection against UV rays thanks to the pigments they contain. Nonetheless, they must be renewed every 3 to 5 years for the south exteriors and also every 8 to ten years for the north facades. Unlike paints, they do not call for sanding prior to revival (a brush stroke is enough to remove the pigment dust). When it comes to natural lacquer paints, they provide even more long lasting security considering that they include fillers (specifically chalk) that create an entire screen versus UV rays. It’s a bit like sun creams; the protection depends on the display’s quality as well as the direct exposure. Drafting Furniture Plan
Surface area Defense
To boost the sturdiness of outdoor timber normally, opt for a discolor, for instance, a mixture of linseed oil as well as turpentine. Some readily readily available timber discolorations are tinted and also supply minor UV security. The benefit of this approach is that no sanding is called for.
For even far better defense, use organic lacquer paint. It will certainly supply ideal protection against ultraviolet rays– favor microporous paints consisting of chalk fillers to let the wood breathe.
Securing external wood naturally can be done with a safety discolor or warm treatment. The option of approach depends upon the qualities that you desire to modify. If particular wood varieties can be used without protection, they need to be stained after a particular duration because the safety tannins will certainly have disappeared. If you do not do this, you will need to have a professional dampness therapy.
Shielding Timber from Water
Securing wood from water is an important function of an outside surface prior to any type of decorative facet. It is recommended to conserve the material with paint, varnish, tarnish, saturator, or oil. Undoubtedly, it is vital to accomplish an actual barrier effect, which should be water-proof if the timber is not to weaken also promptly.
This makes it possible to preserve all-natural, solid, raw, or veneered wood practically in time. It is safeguarded to maintain for years in the face of the numerous weather aggressions ran into. It is durably protected from moisture, rainfall, bad climate, light, sunlight, as well as ultraviolet rays, making it age too soon. Drafting Furniture Plan
Stay Normally Permeable to Moisture
Stay moisture permeableStaying normally absorptive to smoke is very crucial. Wood is composed of plant fibers that have an exceptional affinity with water. It is, consequently, a fragile material that stays easily permeable to water. It remains specifically sensitive to different fluids that penetrate it.
Wood takes in extremely promptly the moisture that is present in the ambient atmosphere. It absorbs water prior to naturally launching it since it is a hygroscopic product. It continues to be in constant stability with its atmosphere, whatever the dampness web content.
These various moisture variations are at the beginning of the common dimensional makeovers of wood. They have the impact of causing deformations that can sometimes be considerable. It works by swelling if the air is also damp. It reduces when the environment comes to be drier.
Rain, showers, electrical storms, and various other bad weather condition that are in contact with the wood can trigger the look of unattractive discolorations, streaks, leaks, and halos. Dampness, infiltration, condensation, and water vapor are also in charge of the premature aging of timber throughout the years. Drafting Furniture Plan
Do Not Avoid Exchanges with The Outside World.
Do not protect against exchanges with the outdoors not prevent communications with the exterior; it needs to be valued. When you intend to secure the timber, a water-repellent item must be applied to stay clear of water from permeating it. It needs to be made certain that it is not impregnated by moisture if it is to last over the long term.
A timber treatment item can only be perfectly ideal if it values the different dampness exchanges. The timber needs to be able to remain to regulate itself with its environment. It is necessary to make certain that the film continues to be completely micro-porous to ensure a good exchange effectiveness.
On the other hand, impermeability and also water rigidity ought to not be perplexed, which are really various notions. Waterproofing must be prohibited when it comes to wood security. Making a timber totally watertight might cause the product to rot in the long-term.
Gas exchange, which manages the wetness material in the timber’s pores, need to never ever be avoided. A wood paint need to enable the substratum to breathe without ever before quiting the inner emptying to the exterior. It must simply stop water from permeating the heart of the timber, not to alter or weaken it.
Selecting a Right Timber Therapy Item
Choosing a timber treatment picking the best timber treatment product is necessary to shield timber effectively in time. There are different types of items that can efficiently preserving this product. One can utilize an item that penetrates deeply, such as oil, impregnation, or saturator.
A passing through therapy supplies more reliable defense than an item that transfers a film on the surface, such as paint, varnish, or sealant. Undoubtedly, while a film-forming item might seem helpful initially, this is not constantly the situation in the long term.
Indeed, they can end up breaking, flaking, fracturing, or removing for many years. Infiltration, water, or humidity penetrates the material, which becomes improperly insulated. It is then necessary to sand or strip the surface area of the wood to bare it once more to be preserved.
Silicones are commonly made use of in timber waterproofing products. These harmful compounds ought to be avoided similarly as petroleum solvents, which are still present in many products. They are not safe to the customer, the atmosphere, or nature. It is much better to pick a bio-sourced product of plant beginning that follows this all-natural product. Drafting Furniture Plan
Keep On A Regular Basis for Adequate Protection.
Maintain for good protection keep consistently for an adequate protection, continues to be an operation that should not be forgotten to execute. Despite the type of waterproofing selected to maintain the wood, it is necessary to maintain it frequently to ensure that the protection continues to be completely effective in time.
Tiresome preparation, fining sand, gritting, or stripping of the surface area can be prevented using an oil, saturator, or impregnation. They have the particularity of protecting the material throughout its mass without developing a film on the surface that can exfoliate afterward.
A waterproofing representative’s function is to protect 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 wood from becoming as well grey over time. It therefore limits the sensation of swelling or contraction.
A non-film-forming water repellent has many benefits for protecting a wooden surface area. It is really efficient versus bad climate thanks to an obstacle effect. Also, it remains extremely effective in nourishing the timber in all its deepness to the material’s very heart. It additionally shields the assistance from light, sun, and ultraviolet rays.
