Outdoor wood has 2 primary opponents: UV (ultraviolet rays from sunlight) as well as humidity. The first causes a type of surface melt – like on our skin, causing little cracks and also greying. Nothing dramatic, the damages is generally visual, and the wood is not affected extensive. Diy Restoring Old Furniture
Wetness postures much more severe problems: if rain does not run or does not vaporize promptly, if the timber continues to be touching the ground or if the moisture can climb by capillary action, the dampness material of the wood will certainly permit the installment of lignivorous fungi that are forerunners to rot and also favor attacks by wood-eating pests. Can chemical preservative treatments be prevented?
Resilient Types, without Sapwood
Some normally durable varieties from our regions can be used without treatment when the timber is laid vertically (risk course 3) and allows good water drainage (cladding, home windows, shutters): in particular Douglas, larch, chestnut, oak, and also cicada. Just the last 3 species are suggested when the wood is laid flat (porch or terrace boards) or touching the ground (threat class 4). These timbers have to likewise be picked and also cut in such a way regarding eliminate the sapwood, the peripheral part of the trunk abundant in sugars, which attracts wood-eating insects.

What Are the Benefits of Safeguarding Your Wood?
Embellishes and Protects
Past maintaining the aesthetic element over time, using a wood oil or a saturator in the defense of timber will revitalize its original shade as well as enhance the grain of the timber while preserving its natural look.
Maintains the Wood
Oiling a timber allows enhancing its dimensional stability durably, therefore decreasing the sensations of deformation (tiling, swelling, and also shrinkage), cracking, or surface splitting.
Natural and also Ecological
Selecting an “Oleobois” safety oil indicates selecting a healthy as well as eco-friendly service; the composition leaves out fungicides, turpentine, as well as any kind of oil derivatives regularly utilized (paraffin, white spirit, …).
Easy and also Economical Maintenance
Upkeep is very easy due to the fact that as soon as fueled oil; wood does not need to be removed or fined sand before renovation: a cleansing with black soap followed by an easy re-oiled surface suffices. Diy Restoring Old Furniture
Greying of The Timber
What Is Timber Graying?
Wood is a product nearly comprised of polysaccharides (cellulose as well as hemicelluloses) as well as lignins that will be broken down under ultraviolet photons’ action. This photodegradation of the lignins, which is likewise accentuated in the presence of water, is accountable for the advancement of the color of the timber. Greying is observed on the timber made use of outdoors with no physical defense and also UV protection. This sensation triggers a change in the initial shade of the raw timber in time, which has a tendency to become grey.
What Are the Consequences of Greying?
Greying or graying, which is a really shallow phenomenon, only impacts the wooden framework’s visual appeals. It does not indicate a structural change and does not influence the solidity of the product. The look of this phenomenon is restricted to the surface of the wood. The loss of architectural longevity (which can reach the wreck of the product) is, for its component, as a result of attacks of biological origin that influence the wood in its mass.
Is it feasible to prevent the greying of the wood without keeping it?
NO – Without finishing items as well as without upkeep, it would certainly be imaginary to assert to be able to avoid the timber from greying.
Will the application of a surface stop the wood from turning grey?
YES – If this application is made frequently, it is possible to avoid this sensation. The hydrophobic nature of the oil highly restricts the wood’s affinity for water as well as for that reason delays its activity. Diy Restoring Old Furniture
Corrected as well as Thermo-Oiled Wood
Several recent processes have made it possible to improve the toughness as well as dimensional security of other species substantially: these are high-temperature heat therapies (210 to 250 ° C )in numerous phases, performed in unique heaters, either under an inert ambience with nitrogen (corrected timber) or with water vapor shots (Finnish heat-treated lumber). The wood handles a lovely brown shade as well as becomes hydrophobic and also very immune to fungal or insect attacks. Nonetheless, the high temperature compromises these woods a little, which can not be made use of for architectural objectives (generally in home siding, parquet, as well as terrace boards).
The so-called homeothermic process does not have this disadvantage: the wood is just heated up to 130 ° C, with an immersion in a mixture based on linseed oil and vegetable oil derivatives, which permits a deep impregnation. This additionally makes sure a much longer resistance to greying as well as does not require routine upkeep. The procedure creators have started to market it in France: three producers in the timber industry have already bought it, and others are in the pipe. The current Wood-Protect process patented by Lapeyre as well as INRA-INPT in Toulouse is of the exact same kind, with impregnation by autoclave and then by soaking at 140 ° C in a mixture of vegetable oil by-products and acetic acid.

High-temperature treatments make the wood completely waterproof as well as fungi immune.
The timber is brought to a temperature between 210 ° C as well as 250 ° C in unique stoves. It after that transforms shade to become darker. The major drawback is that it loses its strength. It can then just be used for cladding or flooring.
Oleothermy is a treatment that consists of 3 phases: home heating to 130 ° C in a rapeseed oil bath, cooling down in a linseed oil bath, as well as drying out. Given that the home heating temperature is lower than the previous approach, the timber is less weak.
Studies have actually revealed that homeothermic heating is valuable when done after boron treatment. Boron has anti-inflammatory properties. The issue is that it is not immune to washing. Thus, the homeothermic makes it feasible to deal with the particle as well as make the timber extra resistant to flames, water, and also shocks. For more information about this method, right here is a doctoral thesis that was done on the subject.
Oils, Spots, as well as Paints
The toughness of specific species such as oak as well as chestnut is primarily as a result of their high tannin material. Nonetheless, these are progressively washed out by rain, which is somewhat acidic. Like other types, oak as well as chestnut, for that reason, need surface defense. Linseed oil with a little turpentine included – to be made use of in heat (it penetrates far better) – is timeless and also affordable protection, water-repellent, as well as delays greying.
Organic wood spots, which are tinted however show the timber grain, provide better defense against UV rays thanks to the pigments they consist of. They ought to be restored 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 prior to renewal (a brush stroke is enough to get rid of the pigment dust). As for organic lacquer paints, they give more resilient security since they include fillers (specifically chalk) that create an entire screen versus UV rays. It’s a bit like sun creams; the security relies on the display’s high quality and the direct exposure. Diy Restoring Old Furniture
To boost the sturdiness of outdoor wood normally, go with a discolor, for instance, a combination of linseed oil as well as turpentine. Some commercially readily available wood stains are colored and give slight UV defense. The advantage of this method is that no sanding is called for.
For even much better protection, use organic lacquer paint. It will supply ideal security versus ultraviolet rays– favor microporous paints consisting of chalk fillers to let the timber breathe.
Safeguarding external wood normally can be performed with a protective discolor or heat treatment. The selection of method depends on the qualities that you desire to customize. If specific timber species can be used without security, they must be discolored after a certain period due to the fact that the protective tannins will certainly have gone away. If you do not do this, you will have to have a specialist moisture therapy.
Protecting Timber from Water
Protecting timber from water is a vital feature of an outside coating prior to any kind of decorative facet. It is recommended to conserve the product with paint, varnish, discolor, saturator, or oil. It is important to attain a real barrier effect, which have to be water-proof if the timber is not to wear away too promptly.
This makes it possible to protect natural, solid, raw, or veneered wood practically in time. It is secured to maintain for several years in the face of the numerous climatic aggressiveness came across. It is durably maintained from moisture, rain, bad weather, light, sun, and ultraviolet rays, making it age prematurely. Diy Restoring Old Furniture
Stay Naturally Absorptive to Wetness
Continue to be wetness permeableStaying normally absorptive to smoke is extremely essential. Wood is composed of plant fibers that have a superb fondness with water. It is, for that reason, a vulnerable material that stays quickly permeable to water. It stays particularly conscious numerous fluids that permeate it.
Wood soaks up really swiftly the moisture that is present in the ambient atmosphere. It takes in water prior to normally releasing it since it is a hygroscopic material. It continues to be in consistent stability with its setting, whatever the wetness material.
These various moisture variations are at the origin of the usual dimensional transformations of wood. They have the impact of creating deformations that can occasionally be considerable. It works by swelling if the air is too humid. It diminishes when the environment becomes drier.
Rain, showers, electrical storms, as well as various other negative weather condition that touch with the timber can create the look of unpleasant spots, touches, leaks, and halos. Wetness, seepage, condensation, as well as water vapor are additionally responsible for the early aging of wood throughout the years. Diy Restoring Old Furniture
Do Not Prevent Exchanges with The Outside World.
Do not prevent exchanges with the outside not avoid communications with the outside; it has to be appreciated. When you intend to shield the timber, a water-repellent product needs to be related to stay clear of water from permeating it. It should be guaranteed that it is not fertilized by moisture if it is to last over the long-term.
A timber treatment item can only be completely appropriate if it respects the various dampness exchanges. The wood has to be able to continue to manage itself with its environment. It is necessary to make sure that the film continues to be adequately micro-porous to assure a good exchange efficiency.
On the other hand, impermeability as well as water tightness must not be puzzled, which are very different concepts. Waterproofing must be forbidden in the case of wood protection. Making a timber completely watertight may trigger the product to rot in the long term.
Gas exchange, which manages the wetness web content in the wood’s pores, have to never ever be protected against. A timber paint need to allow the substrate to breathe without ever stopping the internal evacuation to the outside. It has to just protect against water from penetrating the heart of the wood, not to change or deteriorate it.
Picking a Right Wood Treatment Item
Choosing a wood therapy picking the right wood treatment item is important to shield timber efficiently with time. There are various types of items that can efficiently preserving this product. One can make use of a product that permeates deeply, such as oil, impregnation, or saturator.
A passing through treatment provides a lot more effective protection than a product that deposits a movie on the surface, such as paint, varnish, or sealant, for instance. While a film-forming product may seem beneficial originally, this is not constantly the case in the long term.
They can finish up breaking, flaking, fracturing, or peeling off over the years. Seepage, water, or moisture permeates the material, which ends up being poorly shielded. It is then essential to sand or strip the surface area of the timber to bare it once more to be protected.
Silicones are extensively used in wood waterproofing products. These unsafe materials ought to be avoided similarly as oil solvents, which are still present in several items. They are not safe to the user, the setting, or nature. It is much better to pick a bio-sourced item of plant beginning that follows this natural product. Diy Restoring Old Furniture
Keep Frequently for Adequate Defense.
Keep permanently defense maintain consistently for an adequate defense, continues to be an operation that needs to not be failed to remember to carry out. Despite the type of waterproofing picked to protect the wood, it is essential to maintain it regularly to make sure that the security remains sufficiently efficient over time.
Laborious preparation, sanding, gritting, or removing of the surface can be prevented utilizing an oil, saturator, or impregnation. They have the particularity of safeguarding the product throughout its mass without producing a movie on the surface that can exfoliate afterward.
A waterproofing representative’s function is to shield the timber from stains, marks, rings, as well as day-to-day damage. It is typically related to an anti UV representative that will certainly avoid the timber from coming to be also grey over time. It therefore restricts the sensation of swelling or shrinking.
A non-film-forming water repellent has lots of advantages for preserving a wood surface area. It is really reliable against poor weather thanks to a barrier result. It remains extremely efficient in nourishing the wood in all its deepness to the product’s very heart. It also secures the assistance from light, sun, as well as ultraviolet rays.
