High-quality processing of wooden structures with an antiseptic. How to paint the lining outside the house: choose the paint

To the question I bought a wooden change house, how to process it so that it does not dry out and damp? given by the author I-beam the best answer is tar

Answer from space[guru]
Belinka impregnation. They took polysander color. Super. This paint is with varnish. So smooth lacquer coating, you can wash the tree with a rag. The price is really expensive, but it's worth it. You don't need to paint often. You can also sheathe the change house with siding. Also durable. It is better to take Canadian siding, it does not fade in the sun.

Answer from Alex Mishin[guru]
We bought our change house - the same as yours, lining on the outside, hardboard inside - in 2008. We, however, do not Leningrad region, and Kaluga near the border with Moscow - Obninsk - but for some reason, any wood on our site rots catastrophically, quickly. However, our change house does not rot - the impregnation made by the manufacturer still saves. But there are many other problems. The roof in the very first years had to be completely changed - it was made with gross errors and was desperately flowing. At the same time, we had to throw out the hardboard ceiling, soaked from these leaks, and make a new one from the lining - before installation, we covered it with a protective and decorative impregnation "Holtz-Lazur" pleasant golden color. door frame cracked along the grain of the wood, the screws fall out, and door leaf falls off. (I have now replaced the screws with bolts and nuts - they are still serving). At some point, I had to open the inner hardboard lining in one place - a frame made of timber (5x5) under it turned out to be affected by a black fungus. The lining - more precisely, the trimmings of the lining - with which the change house is sheathed on the outside, shrunken, twisted, and gaps formed between them.
In a word, your change house should be enough for the period you specified, but it hardly makes sense to hope to make something really decent out of it. Probably more right decision it would be to build the same change house to order by local carpenters - I already found such a company a couple of tens of kilometers from our dacha, and the change house ordered from them would cost no more than the one we bought. At the same time, her clear advantage in that it can be wider than the finished one: a purchased change house cannot be wider than 2.30 - the traffic police will not let it pass - and this is clearly not enough. But when you take it ready, they bring it to you, put it on the ground, and you can move in the same day. And you have to pay for this. . .
Here is our cabin - inside and out. Do not pay attention to the barrel on the roof - this is the "water tower" of our summer water supply.

P.S. But the toilet was custom made for us. We processed it immediately. protective agent"Senezh-bio". Sense - zero: boards with outer side for a couple of years completely grayed out. They say that it was necessary to use "Holtz-grunt" - this means is "angrier" than Senezh-Bio and even than Holtz-Lazur. Oh, I wish I knew in time...

Pinotex Aquatex can also be oil

Answer from Ruff[guru]
I would do so. In 2-3 layers with intermediate drying - impregnation with 3 functions: fire protection, mold protection and bark beetle protection. Special attention semi-straight crawl and process from below. For the future: when you buy something ready, at the installation stage, arrange with the workers so that you can immediately treat everything with impregnation hard-to-reach places- floor and roof. Pay them, it's cheap. When the impregnation dries - whatever. You can use yacht varnish (only on very dry wood) in 2 layers, you can use Pinotex, Belinka, Aquatex, and others - which shade you like (I advise not dark, but as light as possible). You can paint with paint in a blue color or paint it under Khokhloma - also only dry. Important: processing with drying oil and any oil is suitable only for oil paint, as a primer.

A wooden change house can be called housing in miniature. Made from natural wood and additionally equipped with shutters and a porch, it will decorate any country cottage area. If necessary, the change house can easily turn into a bath or shower, workshop or economic block, as well as serve as a trade pavilion, car repair shop, dining room.

Benefits of a wooden shed

Temporary wooden structures regardless of the purpose of use, they have many advantages:

• Environmental friendliness of the material. All natural qualities of wood are preserved, and the use of any chemicals is excluded.
• Structural strength. Promotes durability of a wooden change house.
• Comfort. During production, it is given all the necessary qualities, power and water supply systems are installed, plumbing is installed.
• Ease. The change house is established on the facilitated base or on the equal prepared platform or soil. Can be moved to another location.
• The acceptability of the cost, which makes it affordable for purchase.

How to extend the life of the change house?

In order for temporary housing to please with its strength, protect it from moisture and cold, there are several methods of processing and painting - simple and affordable:

• Immediately after acquiring a change house, you should protect the tree with several impregnations: fireproof, from fungus and mold damage, and from bark beetles.
• Impregnation should be carried out with each agent in turn in several layers, allowing time for drying.
• Especially carefully it is necessary to process the floor, trying to get close to it from below.
• If the change house has already been painted, it should be removed old paint and all the accumulated dirt, putty cracks and dry the wood, and then proceed to impregnation and painting.

How to paint a wooden change house?

To cover wood completely dried after impregnation, several types of compositions are suitable:

• It could be alkyd paint, which increases the moisture resistance of the facing material and is resistant to atmospheric precipitation. It is easy to apply and economically consumed.
• Matte alkyd enamel withstands the effects of precipitation and is resistant to the use of detergents. Good resistance to wood wear. Its drying time is 24 hours.
• Acrylic paint has the ability to breathe. It is elastic and able to repeat the deformation of wood without flaking. Its service life is up to 10 years.
• Can be used to paint the shed yacht varnish applied in two layers.
• An extraordinary solution for a temporary house is to burn the wood with a burner (gasoline or gas), and then sand it and paint the surface with a colorless impregnation.

A well-groomed, high-quality change house made of wood is a reliable and protected shelter, comfort and coziness even during temporary residence.

Wooden lining is beautiful, natural material. It is not surprising that so many users around the world prefer it as a finishing and cladding material.

The environmental friendliness and natural beauty of wood not only decorates the room, but also creates a certain microclimate in it. And the lining covered with a dense coating (paint, varnish) allows you to create any decor.

But, the tree has a significant disadvantage, which affects performance characteristics lining - it undergoes rotting, various damages, and also tends to darken.

This article is intended for those who want to protect and at the same time keep the lining in natural form. Consider step by step how and what is better to cover (impregnate, process, paint).

I must say that the “take a brush, paint and paint” method is good, precisely because of its simplicity. But how long will wood painted in this way last? Wouldn't it be better to choose a more thorough and correct approach?

Proper painting wooden lining consists of 4 stages:

Stage 1 - preparing the lining for painting

For eurolining, such a stage will be superfluous, since manufacturers are guided by the European standard, which provides for mandatory primary processing of wood with protective compounds.

Those who bought a standard lining domestic production or is dealing with an already painted surface, it is necessary first of all to carry out the initial processing of the panels.

Preparing a new lining

Preparation of new slats includes:

• sorting. It is known that the intersection of varieties up to 10% is allowed. That is, a batch of first grade lining may contain up to 10% of second grade lamellae. In order not to disturb the surface, they need to be sorted;

• drying. Purchased lamellas must be dry before installation;

• aging in temperature regime premises in which it is planned. It is natural to heat the sauna so that the boards “warm up” makes no sense. But here it is necessary to lie for 2-3 days in the room where they will be installed by the boards;

• removal of defects. The surface defects of the lining include chips, roughness, the appearance of blue, white spots, dead (falling out) knots. On part of the panels, defects can not be touched. This is due to the fact that in the process of work, a short lining will be needed. For example, for finishing under a window or above a door. However, in order to proceed with the installation on an open surface, the boards must be cleaned of defects by bleaching (for this purpose, it is recommended to use SenezhNeo or Hoarfrost). Grease stains can be removed by deresining - rubbing with a 25% acetone solution. Roughness is removed with sandpaper (sandpaper) or a metal brush.

Preparation of the operated (old) lining

Unfortunately, painting a wooden lining is not an action that can be performed once for the entire period of its operation. Painting lining is a process that needs to be repeated periodically.

In the event that it is necessary to paint previously painted, varnished surfaces, it is also necessary to carry out pre-processing panels.

When to paint the lining:

• peeling of the bottom layer of paint;

• loss of lamella color;

• loss of gloss of paint or varnish;

• appearance significant defect, for example, the ingress of fat, oil, solvent, other dye, the manifestation of fungi on the surface of the lining;

• new style, thirst for change and fashion. For example, the existing color of the lining does not fit into the updated interior of the house and other factors.

How to clean the lining from varnish, paint and dirt

There are two ways to remove old paint or varnish from the lining:

• Mechanical. In this case, the existing coating is removed with a scraper, wire brush or blow dryer and a spatula. To completely remove the paint, you need to treat the boards with a solution of soda (100 g of soda for 1 liter of water). A significant disadvantage method is the probability of damage to the lamellas by the scraper. Tip: this method is suitable for cleaning the lining from oil paint.

• Chemical. It involves the use of various synthetic solutions and compositions (washes, softeners), which contribute to the peeling of the paint from the base. It is worth noting that chemical method pretty aggressive. Work with solutions in a well-ventilated area with the necessary equipment personal protection. After removing the surface layer, the lamellas should be washed with water or rubbed with white spirit.

If the house is sheathed on the outside with clapboard, then this material, left untreated, will quickly fail under the influence external factors. Improper painting will also not increase its service life. So how to process this cladding outside the house so that it lasts a long time?

Impact of harmful factors

There was a time when only wood was used for lining. But today the choice of materials has expanded.

If the walls of the house are sheathed with wood, they will be more exposed to weather conditions than lining made of metal or plastic. From wooden species it is better to choose coniferous. But they won't last long without treatment. They are influenced by various factors:

1. Change of humidity, freezing of walls in winter, overheating in summer.
2. The destruction of wood fibers under the action of ultraviolet radiation.
3. Influence of microorganisms (fungi) living in the environment.
4. Mold formation due to improper installation of lining.
5. Insects, rodents, pests.

If you ignore these points, the cladding of the house will dry out or not hold its shape. To prevent this from happening, it is processed immediately after installation. If this is not possible, then you should think about how to cover the skin after cleaning.

When buying a lining, it is advisable to check it for humidity, which should not exceed 12%.

Preparing for painting

The complexity of painting depends on what surface the paint is applied to. Most often it is necessary to update the old or untreated surface. If you do not take care of the proper cleaning of the material, there will be little sense from such processing. The surface will again become unusable.

The old lining is cleaned of the previous layers of paint, dust, dirt, treated with an antiseptic.

Steps required before painting:

1. Major repairs need to be made first. If there are damaged strips, replace. Seal cracks and joints.
2. Then clean the surface: remove dirt, dust. If the lining has been painted, remove the previous layers.
3. If the old skin is infected with mold or other fungus, the surface is cleaned. And then treated with a special antifungal solution.
4. In order for the paint to lay down more firmly, the base is degreased with white spirit, gasoline or detergent in which alkali is present.
5. The surface is being sanded sandpaper. If the wooden planks have become rough, you can walk with medium sandpaper, followed by fine sandpaper.
6. The next step is to prime the surface.

The lining is dried before painting.

How to prime the lining before painting

To prevent damage to the tree, it is necessary to choose the right impregnation.

Primers protect the surface of the lining from excessive moisture and penetrate deep into the wood. In summer, it will not dry out, and under the influence of precipitation it will not become damp.

Also, the impregnation prevents the harmful effects of ultraviolet radiation, and when using transparent, it emphasizes natural beauty tree.

An opaque primer hides skin defects, and leaves the relief the same.

Types of coloring composition

Pros and cons of oil-based paints

After preparing the surface, the question arises of how to paint the lining outside the house. Using oil paint is the standard, proven way to paint. Their advantages:

• do not deteriorate with sudden changes in temperature and moisture;
• at proper processing the surface coating does not allow the reproduction of fungi and other microorganisms;
• the composition passes air;
• penetrating deep into the tree, the paint protects the lining from moisture. This is a major plus, as it allows you to wash the surface without fear.

Despite so many positive properties, oil-based dye has two negative qualities:

1. Long drying time. It dries in 1-5 days. The surface remains sticky and collects fluff, midges or debris.
2. Color change that appears on light and dark colors. With this factor in mind, it is better to choose neutral shades.

The choice of oil-based dye allows you to paint without the help of a specialist.

Acrylic paint for outdoor use

It is expensive, but of good quality. It contains watercolor and oil components.

Advantages of acrylic paints:

• Durability and wear resistance (does not lose original view 5-10 years).
• Drying time - 3-4 days.
• The colors are bright and saturated.
• Possibility of mixing with each other (any shade is selected).
• Non-combustible.
• The composition does not penetrate deep into the tree and allows it to breathe.
• Easy to apply.
• Density allows the use of a spray gun.
• The plastic texture of the substance prevents the appearance of cracks.
• Repels dirt.
• Ease of use.

Of the shortcomings acrylic compounds stand out:

1. high price;
2. instability at sub-zero temperature;
3. toxicity.

Before buying paint, it is best to carefully compare prices. The foreign version will cost more than the domestic one.

Facade composition with alkyd base

This paint is based on alkyd resins and modified oils. She dries quickly.

Its main advantages are:

• resistance to low temperatures- up to 30 degrees;
• fast drying - up to 9 hours;
• bright matte or glossy colors;
• gradual wear;
• moisture protection.

Disadvantages:

• fast fading;
• toxicity.

Alkyd-based varnishes

Varnishes and paints on alkyd base have similar composition, but their characteristics are different. The varnish is based on alkyd resins. But added to them fatty acid and natural vegetable oils. They endow it with new properties:

• thorough penetration into the wood;
• resistance to temperature and humidity changes;
• protection against the appearance of fungal and other infections;
• uniform coverage of the base;
• glossiness or haze of the film;
• color retention up to 10 years.

The only drawback of such a coating is the drying time (1-2 days) and a pungent odor.

Selection of paintwork material

When choosing a coating for lining, it is worth considering the conditions environment, the type of wood and its previous foundation.

You need to pay attention to the following characteristics:

1. The composition must protect the skin from sudden changes in temperature.
2. It should not change color when exposed to the sun.
3. After application, the coating should last 5 years.

But the main thing in painting wood paneling- this is a quality work that will please the eye of the owner and passers-by.

Often change houses in the country or on a construction site are built using wood. this one good construction material, which is malleable and easy to use, but it is prone to decay. Accordingly, in order to extend the life of the building, it is necessary to protect the wood from the effects of moisture, fungus, and insects. The bottom of the change house is especially susceptible to destruction: it must be given priority attention.

Flooring materials

If necessary, you can choose a finished structure, which remains to be delivered to the site and installed. Her wooden elements have already undergone the necessary processing and are characterized by resistance to environmental factors, although in addition the bottom boards can be varnished.

It is more difficult to assemble the floor yourself. For this, it is recommended to use dried and planed wood, for example, tongue and groove board. It is desirable that the thickness of the board is 35 mm. Cut raw wood smaller thickness suitable for creating subfloors.

Ways to protect against decay

As practice shows, the easiest way is to protect wood from decay, generally eliminating the ingress of moisture on its surface. Therefore, the bottom of the change house is most often hemmed with sheets of roofing material. This material is designed specifically for waterproofing surfaces and has such advantages as:

• relative durability;
• light weight;
• versatility, ease of use.

In addition to roofing felt, galvanized steel sheets can be used to finish the bottom of change houses. They are characterized by durability and long service life. True, galvanized sheets are intended for roofing, therefore, it may be difficult to install them under the bottom of a residential building due to the wavy surface of the material.

If it is impossible to exclude moisture from the wooden parts, the material will have to be processed paintwork materials. First of all, it is a natural drying oil - an impregnation that penetrates deep into the wood fibers and prevents them from being saturated with moisture. Drying oil is applied to the surface of the material in hot form, heated in a water bath. Immediately after processing, the wood is heated building hair dryer or ironed with an iron heated to a temperature of more than 150 degrees. This procedure is repeated several times until the tree completely absorbs the drying oil.

It is advisable to oil the wood before use. After the installation of the bottom of the change house is completed, the joints of the boards can be covered with thick paint - this is one of the most effective ways prevent floor rotting, although labor intensive.

Another way to protect wood is painting. In this case, the boards must be dry. A primer layer is first applied to their surface, then painted in 1-2 layers oil paints based on zinc white, iron or lead minium. You can start painting only if you are absolutely convinced that there is no water access to the tree.
