Than and how to paint the OSB. Soil and paint for OSB plates

A rather popular material in construction is the OSB, a focusing and overall slab, which is characterized by its lightness, strength and affordable cost. But as you know, this production resource requires additional decoration, which allows the owners to realize the most extraordinary ideas in the design of buildings. Therefore, in many non -specialized masters, questions arise about which paint to paint the OSB, which coatings to pay attention to and what you need to know about them? About this further in the article.

OSB - Features of the material

OSB is a material that includes chips of wood, which are connected by waterproof synthetic resins. For their production, pressed equipment is used to form plates of three to four layers. In the construction of the OSB, they are used with different purposes, they are suitable for:

• structures of frame houses;
• sheathing walls and ceilings in rooms;
• installation of formwork;
• manufacturing of structural furniture elements, etc.

With proper production manufacturing, ready -made slabs are considered an environmentally friendly and safe product that is several varieties. So, the OSB is distinguished by four formats:

1. OSB -1 is characterized by low indicators of strength and moisture resistance, which is why this brand is most often used in the process of manufacturing furniture and conducting internal work.

2. OSB - 2 with high strength indicators is characterized by low moisture resistance, so this plate is suitable for the production of partitions, etc.

3. The OSB brand - 3 is a sufficiently strong and moisture -resistant material, which is actively used in organizing external construction work.

4. OSB - 4 is considered the best resource from this category, due to its highest possible indicators of moisture resistance, is used in the creation of roofs, walls of buildings, bearing elements, etc.

The strength and moisture resistance of the material depends on what percentage of adhesive was used in the production process, as well as on the number of layers of pressed chips. As for the size of the plates, they are standard: 122*244 cm, 122*336 cm, 125*375 cm, etc.

It is worth noting that the oriented-brown plate has a low fire hazard, is not subjected to processes as rotting, stratification, and the development of mold. Its technological characteristics in many cases exceed wood resources such as chipboard, plywood, and fiberboard. In addition, this material protects the buildings from excessive sounds well, does not deform when contacting water, perfectly retains heat in the room.

Structures built from pressed plates are distinguished by a long operational period. According to the recommendations of experts, the owners buying the OSB should check the certificates of construction products, since it is worth considering the fact that the phenol that is part of the resins can harm human health, and its safe alternative formaldehyde is a worthy option. Therefore, it is better to buy materials with an eco mark. A number of worthy world manufacturers of the OSB include such brands:

• Norbord;
• Egger;
• Ainsworth;
• Glunz;
• Grant, etc.

It is worth noting that Chinese manufacturers offer products at a low price, but its quality is suitable only for external use.

Is it possible to paint the OSB with paint?

On the construction market, of course, there are oriented-brown slabs, previously covered with paint and varnishes, but their cost is much higher than a clean resource. But nevertheless, most often the owners acquire those sheets that in the process require additional processing and for this purpose use various varnishes, paints and other similar products, allowing not only to extend the operational period of the OSB, to give harmony to the appearance of the building, but also to hide the irregularities chip texture of the material. The paint for the OSB of the slab, the choice of which is based on several important rules, can be of any color, the main thing is that it does not include malicious pigments. So, about a variety of coatings, see the table.

A variety of antibacterial impregnations are also actively used to process the OSB, which allow you to give the material of the tinted effect. It is worth saying that in order for the OSB to be painted with paint naturally and does not lose its original characteristics, it is necessary to take into account the features of the wood resource, composition, coating and properly prepare the surface for processing.

Stages of preparing the surface of the OSB for coating with colorful means

If you apply colorful products directly to the wood plate itself, without preliminary processing, then the material can be swollen, lose its perfect original appearance. Finishing and painting building resources is a whole technological process in which in order to achieve ideal results it is necessary to act in stages. So, before using the paint, it is necessary to prepare the surface of the OSB.

1. In order for the wood material to absorb excess primers and the paints must be grinded of the surface, which will allow you to smooth out the irregularities of the texture. At this stage, the master will need a special tool - a grinding machine. Particular attention should be paid when grinding stoves of brands 3 and 4. If the OSB does not see special violations in the structure, you can do with ordinary grinding paper.

2. At the next stage, they work with places that form gross irregularities on the plates, most often these are joints, areas of use of self -tapping screws, etc. For this, the masters introduce special oil compounds, putty, decorative strips, etc. into the workflow.

3. The next working stage is associated with the application of the primer. To do this, you will need varnishes with acrylic or acrylic-polyurethane composition. For its application, wide brushes are best suited. The product must be applied evenly over the entire area of \u200b\u200bthe stove, slowly.

4. Paints for OSB plates can be bought in any construction store, after which it is recommended to work with them using generally accepted technology. The essence of working with such means is to apply several layers, while their density increases in the area of \u200b\u200bthe edges. It is worth considering that the movement of the brush should be performed in one direction. You need to dry the plates panels with a stable temperature regime, strictly neutralizing drafts.

It is necessary to recall the next nuance that for alkyd enamels the stage of painting is considered the last, since they do not require additional finishes. But in the case of oil and acrylic, so the varnishing process is added here, which allows you to get the most strong surface.

Paint for the OSB of plates indoors

As practice shows for painting the room on the inside, a wide variety of materials are used. And this is not prohibited, the main thing is that the owner is confident in their safety, and for this he must request appropriate quality certificates when buying, as well as be interested in the composition of colorful tools. Also, when choosing a coating, it is worth taking into account the time that the owner has for repair work. After all, as you know, for example, oil paints are distinguished by the property of prolonged drying, but are considered a worthy option for decorative decoration of the room.

In comparison, alkyd enamels quickly dry out and do not require additional varnish processing, which means that this tool is suitable for those who want to quickly conduct interior decoration of the rooms. Painting the OSB plates inside the room allows an acrylic paint to obtain as a result a surface lends itself to both cleaning and washing. It is not recommended to use ordinary water emulsion for the decoration of the OSB. For oriented-brown stoves, funds are best suited, which include organic pigments.

In the process of staining pressed wood material, masters will need instruments such as brush, rollers, spray guns (to perform a large amount of work). Before distributing colorful material around the perimeter, it is best for a start to paint a small area of \u200b\u200bthe stove, evaluate how smoothly the selected remedy lies, when buying which you need to clarify whether it is suitable for wooden surfaces. With additional processing with varnish compounds, applying several layers, it is required to withstand a temporary gap, which is at least 12 hours. It must also be said that paints are applied to the surface of the OSB by unlimited layers, until a 100 % monophonic effect is obtained.

Paint for OSB plates from the outside

Facade paint for OSB plates can also be varied in nature. Along with oil, acrylic and alkyd coatings, funds that include latex polymers can also be used. Good waterproof and atmosphere with a pure property with a pure property are characterized by means, which include alkyd resins. It is the colors from this category that will be able to reliably protect the OSB outside, since they are characterized by frost resistance, low abrasion, etc. The low toxicity of this dye is no less important. If the master decided to use alkyd paints, he has the opportunity to choose colors from a wide range of matte and glossy enamels. It is worth remembering that applying colorful material of this group is recommended on a dry, clean wood surface.

Acrylic agents are no less in demand for the processing of OSB outside, a distinctive feature of which is a high level of water in the composition. They are absolutely practical and, with proper use and application, do not actually cause swelling of the stove. This species is recommended to apply leisurely, in a small amount, this will allow water molecules to evaporate faster. It is worth noting such facade materials as silicone water -based compounds, because their advantages are considered: anti -freet, vapor permeability, as well as a high level of adhesion, moreover, most of them are characterized by antibacterial properties.

Thus, we can conclude that the choice of colorful material for the OSB is a choice of purely relating the hosts coming from the disposable budget and the purpose of the construction facility. The main thing is that the masters remember that the OSB is still the original wood resource, which requires special care and should not be subjected to excessive clash with an increased level of moisture. Therefore, any oil, acrylic, alkyd and other compounds, with the right choice and application, will become good protection for the construction from a oriented-stove.
