Means to "eternal" wood: choose carefully

How to protect structures made of wood from mold, fungi, UV and fire

In a beautiful, eco-friendly and "breathing" wood is only one drawback - it is fragile to external influences, and therefore short-lived material. Our ancestors were trying to improve wood resistance to moisture, sun and insects, treating her homemade impregnation of salt and vinegar, and other folk remedies. Now on the market many different specialized formulations, and many of them really work well. How to understand them and how to choose a suitable for certain tasks, we understand with the technical expert Sagus, manufacturer of the well-known bleach and other tools of this brand.

Why wood must be protected

Wood does not tolerate any interference. In nature tree bark protects and logs, lumber or boards do not have any protection. Different wood species have different resistance to external influences, but the most commonly used in construction are always losing their property from the effects of:

• Precipitation and high humidity;
• Sun (ultraviolet light);
• wind;
• Harmful insects;
• Pathogenic organisms (bacteria, fungi, and the moss).

In addition, wood is easy to light up, most often die in fires is the wooden houses.

There is no universal structure that could protect the wood from all these types of effects, but there are tools for different purposes, which are well solve certain tasks.

This chemical means by which you can effectively combat fungal diseases, mildew, UV light and insects. They are also suitable for combating fungus and mold on all mineral materials: brick, concrete, etc.

Means for protection against biological damage

The main enemy of wood - moisture. Penetrating into a tree structure, it creates an ideal environment for biological destroyers.

Faced with mushroom kingdom in his freshly built house. Fungi (mold) began to grow on the floor, where there were black streaks on the floorboard. This shaggy forest Poper that although the cut off and eat potatoes.

Mold, fungi and harmful insects destroy the tree structure in different ways.

But from any kind of biological factors helps antiseptic protection.

Antiseptic - This impregnation, which gives wood the additional properties. The deeper it penetrates into the wood, the better it protects against mold, fungus and insects.

Technical Specialist

Without the use of an antiseptic wooden structure under severe operating conditions inevitably collapses. The moisture will penetrate into the material, and soon you will notice signs of wood-destroying fungi, and then the insects that like to settle in loose cellulose fibers.

At the present market are two types of antiseptics: one destroy fungal cells, and the second block of the enzymes and, roughly speaking, make them die of hunger.

Antiseptic function - to be fed with the outer layer of wood salts, moisture and prevent any bad influence on the biology of the tree.

Oil and organikorastovrimye antiseptics referred to nevymyvaemym; Water-based antiseptics may be difficulties or legkovymyvaemymi. But the water-soluble antiseptic from trusted manufacturers able to serve up to 25 years.

Technical Specialist

Antiseptics produced by our company are designed to protect against biological lesions outdoors and indoors, they working in a humid climate, in prolonged contact with the soil and organic waste and withstand long-term exposure moisture. And even in conditions of high complexity to protect the wood from 15 to 25 years.

The most popular of antiseptics are for wood protection in high humidity conditions, including when it is in contact with moist soil.

Such antiseptic applied to the prepared surface of the dry (moisture content above 25%), which does not have residual cortex, phloem and traces of old coatings, interfering antiseptic to penetrate into the wood.

Technical Specialist

Do not apply an antiseptic to the surface, which are signs of biological destruction. In this case, we recommend that you first use bleachAnd then wait until the wood is completely dry, and then apply an antiseptic. The surface treated in this manner, will serve for many years.

Means for protection against fire

Wooden buildings are easily ignited and burn quickly. Before the advent of chemical agents to contain the spread of fire, the fire could carry half the city. Fire protection - that's what the owner of the wooden house can not be ignored in any case.

Fire protection do you need. Firstly, for myself: God forbid, a fire - FIRE wood to light will be much longer. And secondly, because there SNIP 2.01.02-85 "Fire prevention rules".

Many manufacturers produce ognebiozaschitnye tools that protect both from the spread of fire, and from mold, fungi and insects, working as a "two in one".

Members of our portal conducted its own tests: pieces of wood treated with fire protection and tried to set fire to them. In the course of these experiments, it was found out that the fire protection really works.

Technical Specialist

Wood treated ognebiozaschitoy, during combustion of coke and creates difficultly outer layer that delays the propagation of the flame. When testing wood treated with our fire protection, it delayed the spread of fire. Fire protection coped with its task.

In ognezaschinyh impregnations based flame retardant used is an aqueous solution of salts (boron, silicon, and other acids). When soaking into the structure of wood they alter its properties (that is not burned). Was added and the film-forming agent (a water-soluble - acrylic) to the surface of the tree retardants are not washed out with water.

Until recently, wood preservatives from the fire produced in powders, and now it is most often concentrates or ready-made liquid solutions - they are more effective and safe. fire protection means are divided into classes, the first - the most effective. This is exactly the case when the savings and buy a "simpler, but cheaper" can not.

Types of flame retardants on the principle of action

Until recently it was believed that only works industrial fire protection timber. But now there are effective and qualitative tools that can be applied with brush or spray at home.

Agent is applied in several stages, with no gaps, focusing on places of cracks and structural connections. The number of surface treatments and fire protection depends on the wood species and on its density, on the extent smooth surfaced, and even on how it is positioned in the structure: vertically, horizontally, or obliquely. And, of course, the purpose of the application: to reach the group II fire-resistance, flow agents should be two times less than in group I, and for a simple antiseptic - three times less. There suppressants which can be applied using the "wet on wet", without waiting for the previous coat to dry.

The service life of high-quality ognebiozaschity varies depending on operating conditions and averages:

• 5 years at an external processing;
• 9 years under the film of protective and decorative compositions;
• 15 years indoors.

If the operating conditions are severe, and the flame-retardant coating is constantly in contact with water or soil, it should be updated as leaching from wood.

Technical Specialist

By the selection should be approached with particular care of such compositions - you choose a drug that might save your life in case of fire in your home. And here it is necessary to pay attention not only and not so much on the decorative properties of the drug, as its main purpose - it must make the tree slow-burning material, flame propagation delay before the arrival of the fire, or do not even give the house burn, and thus save not only lives but also property.
 Ognebiozaschitnye drugs should have fire certificates and undergo all the necessary tests on the "aging" and "flammability". We have always paid special attention to the quality of our products, because quality - it's not just the good name of the manufacturer, but also save lives.

conclusions

Protective equipment extend the life of wood products, but will a shame to spend money for nothing and buy low-quality composition. Therefore, regardless of its purpose, you need to carefully read the etiquette and look primarily at:

• Life time. If specified, it 30-40, look smallest subscript letters that such a result is only achieved deep impregnation method (as an industrial technology);
• Product consumption. On average bioprotective means it is 200-250 g / m², for fire protection - 400-600 g / m². The cheaper and inefficient structure, the more consumption - all of the savings is reduced to zero.
• Certificate of conformity. He confirms the safety of the drug, and should be in every wood preservatives, regardless of its destination.
• Multigrade. destination multigrade formulations allow building work in winter, when the moisture from the wood is frozen, and the heat (at temperatures from -15 to +20 ⁰S).
• Manufacturer. For the manufacture of high-quality protective equipment need high-tech production lines, which can not afford a small unknown company.
• Price-quality ratio. In the market there is a very high-quality impregnation humane price.
