The best antiseptics for wood: how to choose a protective impregnation against fungus + Reviews

Despite the emergence of modern building materials, wood occupies one of the dominant places. To preserve all the best qualities of wood (even super-strong and elite), antiseptic treatment is required. Today, there are different compositions on the domestic market, both from domestic and foreign manufacturers. To choose the right wood impregnation, you should take into account several recommendations from experts.

1. First of all, you need to pay attention to the scope of application. Some formulations are intended for internal use, while others are created for external use.
2. The impregnation should not only effectively repel water, but also repel insects and suppress the proliferation of microorganisms. And if manufacturers add harmful chemical compounds to the composition for external use, then a modern product for internal use is made without organic solvents.
3. It is very profitable to buy formulations that provide comprehensive protection. For example, there are products that protect wood from biological damage and from fire at the same time.

Our review includes the best wood preservatives. The rating was compiled taking into account the opinions of experts and reviews of Russian consumers.

Impregnation or antiseptic for wood: which is better?

It is recommended to purchase antiseptic agents, as they combine impregnating, water-repellent, and antibacterial properties.

How to apply antiseptic to wood?

Antiseptic treatment is carried out by deep (immersion) or surface (spray) treatment. The impregnation method depends on the species, part and condition of the wood. Universal spraying methods for wood:

• application by brush, roller;
• spraying with a spray gun;
• capillary (dry) antiseptic;
• immersion in the solution for 1-2 minutes.

What is the consumption of antiseptic for wood, wood per 1m2?

The consumption of antiseptic per 1 m2 depends on the structure of the material. For example, an edged board without planing has greater porosity. Accordingly, it absorbs more. After planing, the pores close and the degree of impregnation decreases. You can calculate the consumption as follows: 100 ml per 1 m2 for planed boards and 150 m2 for edged boards.

The need to treat healthy breeds

Regardless of the type of tree, after it is cut down, the fibers inside die off. This promotes the rapid development of bacteria that begin to feed on it. During eating, enzymes are released, without which it is impossible to process organic compounds. However, microorganisms are unable to reproduce when exposed to temperature, water or nutrients. It is also important to know that there are 2 types of saprophytes:

1. Wood destroying.
2. Coloring.

The second variety reproduces only on wood that has natural moisture. The main concentration is in the sapwood part. These microorganisms rarely penetrate deep inside, but it does happen.

During reproduction and consumption, wood-coloring saprophytes are able to give the material a different color. For example, red, yellow or even green.

They are resistant to temperatures of +50-70 degrees and are completely destroyed only when exposed to 80 degrees Celsius and above. These microorganisms do not affect the strength characteristics in any way, since they are not able to affect lignin.

However, there is nothing positive about these bacteria, since they may indicate the presence of wood-destroying saprophytes, and this variety is capable of processing lignin, which negatively affects the strength of the structure. That is why in production, before working with wood, it is completely dried, after which it is subjected to high-temperature treatment and antiseptic compounds are applied.

Bacteria are not the only danger for this material. Mold, algae and, most unpleasantly, insects can also live inside.

Mold is dangerous for wood, as it provokes putrefactive processes, while algae only spoils the noble appearance. Most of all, it is necessary to protect the material from bark beetles, termites, woodcutters and grinders. These insects are not so easy to remove. Of course, there are various formulations on the market, but most reviews indicate that not all of them help get rid of them completely.

UV protection

Structures built from wood will certainly lose their original presentable appearance over time due to the fact that they are constantly exposed to damaging ultraviolet (sun) rays. To prevent such situations, it is necessary to promptly carry out appropriate treatment of structures with special compounds intended for these purposes. As a rule, they have special additives and pigments in their structure that significantly reduce the destructive ultraviolet effect.

Practice shows that applying such a product to wood will protect it from the harmful effects of ultraviolet radiation for 8 to 10 years. At the end of this period, the impregnation will need to be renewed. If the protective solution is colorless, it must be renewed every three to four years.

Manufacturers of wood preservatives

The correct choice of any product begins with getting to know the manufacturing companies. In this case, experts also studied brands presented on the domestic and global markets, analyzed reviews and reputation. The best antiseptics for wood were offered by several companies:

• Neomid is a Russian brand of high-tech professional preparations for processing and protecting building materials. Belongs to the trading and production company Ekspertekologiya-Neohim. Its facilities, production bases and warehouses are concentrated in Moscow and St. Petersburg.
• Senezh-preparations is a leading specialized enterprise in Russia that develops, produces and sells a full range of protective products for wood raw materials. The trademark is officially registered, despite its relatively recent foundation, the products are rapidly gaining popularity.
• Osmo is a German manufacturer of environmentally friendly, natural oils and wax-based paints. They are used to process wood to increase service life, strength, and structural integrity. A series of special cleaning and care products are based on the characteristics of different breeds and their scope of application.
• Tikkurila is a large Finnish brand of paint and varnish products, founded back in 1862. Initially it was an oil mill, but 150 years of painstaking work completely changed the direction. Products today are environmentally friendly, convenient solutions for consumers and professionals, and a huge selection of interior materials.
• Biosept (Woodmaster) is a Belarusian manufacturer of paints, stains, fire-retardant impregnations, and antiseptic primers for the preventive protection of wood. All of them are difficult to wash out and have a long service life. Products undergo thorough quality control and compliance with GOST standards.
• Aquatex is a leader in the segment of protective and decorative compounds used to treat wood building materials. The company has maintained a stable position in the Russian market for more than 20 years. Acts as an official dealer of treatment facilities; over 4,000 septic tanks have been installed.
• Novocolor is a world-famous company from Italy, founded in 1982. High-tech equipment produces plasters and paints, due to which the brand has become the standard for famous architectural coatings and high-quality interior decorative effects.

Benefits of using a protective agent

An antiseptic is a special liquid that is applied and permeates the wood, restoring lost positive properties and giving the material additional protection. The product protects the material from the negative effects of various bacteria, mold, blue stains and other microorganisms that eat cellulose.

Before using antiseptics, you must wear gloves and a mask. This is a mandatory requirement, since this substance contains oxidizing agents and fungicides. If you neglect this rule, problems with the respiratory tract may occur.

Oxidizing agents are necessary to destroy fungus, so they are the main component in the composition. Fungicides are designed to block the enzymes that saprophytes secrete. This element is present in the composition in the form of organic or inorganic compounds.

Each antiseptic has a liquid consistency. This allows you to penetrate the tree faster. Moreover, the deeper the substances penetrate inside, the higher the effectiveness of the composition.

Main advantages:

• protection of the structure from insects and bacteria;
• blue discoloration will not form on the surface;
• the chance of cracks forming in wood is minimal;
• the surface will be prepared for paint and varnish activities.

In addition to fungicides and an oxidizer, the composition contains medicinal substances that prevent the proliferation of fungus, increase resistance to UV rays, strengthen the material, etc.

Importance of Antiseptic

As a material, wood has significant advantages over other options:

• Affordable price. A person can build a house or a bathhouse by spending a little money.
• Ease of processing. If a beam or board turns out to be uneven or long, you can always trim/shorten it.
• Environmental friendliness and safety.

All these positive qualities make wood one of the most sought-after materials on the market. It is used not only for building a bathhouse. It is also suitable for the construction of residential buildings.

Regardless of the species, there are only 2 important components in the tree:

1. Lignin.
2. Cellulose.

The latter is a polymer material that has a beautiful linear structure and flexibility. In contrast, lignin is multidimensional, which gives it sufficient strength and allows it to withstand high loads without consequences.

At the construction stage, it is necessary to remember that wood is a “living” material. To ensure that it lasts as long as possible and does not deteriorate after the first winter, it is important to pay attention to:

• Atmospheric phenomena in the area of ​​construction of the building. It is necessary to calculate the average temperature of each season, the relative humidity and what part is constantly exposed to ultraviolet radiation.
• Biological factors. For example, we must not forget that wood is most susceptible to mold and pathogenic bacteria, which in a short period reduce all beneficial properties to zero.

However, both of these problems are easily solved with antiseptic agents, which are sold in every hardware store. Periodic treatment helps to extend the service life and has a positive effect on the external condition.
