OSB Plate 05/05/2017

What material is suitable for painting OSB boards on the front

Hardly anyone will come up with the idea to coat the OSB boards the facade of brick or block houses. But this solution is perfect for houses of frame or half-timbered because, with the help of oriented chipboards created a sandwich with a layer of insulation in the middle. Question exterior finish for these panels is very relevant. You can, of course, sheathing house siding or brick ceramic, but these options are too costly in terms of money and labor. Much cheaper and easier to solve the issue with staining. But, here's how and what to paint OSB plate on the front of the house need to carefully consider.

Why the need for painting plates

OSB is a very lightweight, warm, easy to cut out the wall material, which is suitable for construction of exterior structures, interior walls and partitions. Panels are stamps for the outer side are more dense products marked with numbers 3 or 4. Since the panels are made by compression of wood chips and adhesive, the products are considered to be breathable, environmentally friendly, but is sensitive to atmospheric influences.

In the name of the encrypted essence of the product. Wood shavings and wood chips when the molding plates are oriented in the extreme planes longitudinally, and in the middle of the product — across the grain. Mainly due to this and created basic strength and thermal insulation performance of OSB boards. The surface of the panels very nice and warm to the touch, but has a controversial appearance. This is one of the reasons why they need to paint. Significant, but not major. The main objective of this action with the help of paint to protect the material itself, and the house in General, from damage, moisture, mold, fungus and other troubles from the outside. The products themselves are considered to be moisture proof, but its connections are very vulnerable. Therefore, the facades made of OSB boards, is sure to undergo exterior painting. Before final finishing, they must be cleaned of dust, putty, and cover the primer.

It is very important between the different stages of the production of painting works to make the exposure. After the putty the drying process should last no less than 12 hours, the same time needed for full drying of the primer.

Types of paints for painting OSB boards for facade

Modern building materials market offers many types of paint products. But not every paint may be suitable to paint the OSB plate on the facade. Than and how correctly to paint, should be addressed after a thorough acquaintance with the properties of paints and their financial resources. When choosing colors you need to remember that oriented-strand panel on 90% consist of wood. So, the scope and their properties it is necessary to pay attention in the first place. Consider some of the types of paint products in more detail.

Alkyd

Alkyd paints for painting the facades of the most loved by decorators and home-grown builders. Such paint is well absorbed into wood, dries quickly due to its water component. But related to this is a small disadvantage of this paint. It must be stored only at zero temperature, while in the hardened state it is able to withstand frost down to 30 degrees. Negative features can also include low resistance to fire, alkali. But in spite of this, paint this class is popular because:

  • the lack of odor, harmful emissions;
  • quick drying, color retention over a long time, that is, do not fade;
  • excellent covering power or ability to create a flat, smooth surface without sagging;
  • long service life without changing the quality;
  • a relatively attractive price.

Acrylic

Acrylic exterior paint for external works popular not less than alkyd. They consist of a polymer component, colorant and water. The most important feature, important for service outside the premises the ability to paint to create on the substrate a solid film. At the same time acrylics endowed with good adhesion to salt. These two characteristics significantly affect the demand of these paints for facades. Manufacturers have learned how to create acrylic blend not only beautiful, saturated colors in the widest spectrum, but with different physical indicators. The surfaces processed with acrylic paints can be matte or glossy, transparent or deaf. In addition, they:

  • dry quickly, have sufficient strength;
  • suitable for coating porous, loose surfaces, such paints do not spread;
  • have excellent water and vapor resistance;
  • paints are resistant to sudden changes in temperature, good resistance to weather problems.

Oil

Oil

Paint oil-based are classified as the most traditional and long-standing. But, in comparison with modern coatings, they will definitely lose their positions, since, in spite of fame, have some harmful qualities, such as:

  • increased toxicity with oil paints is recommended to work only in a protective, even in the street;
  • requires long time for drying, as the basis for the manufacture of such paints is linseed oil;
  • need experience for a uniform coating because of the staining are often formed streaks;
  • small resistance to weathering, and thus short lifetime, annual updates.

The positive aspects include good absorption in the surface, unpretentiousness to the conditions of storage. Thickened paint easily diluted with linseed oil.

Latex

Paint on latex-based excellent on materials made of wood. For the production of such paints using plain water, acrylic resin and latex polymer liquid substance. It turns ordinary acrylic enamel in an ink mixture that has additional properties. To the basic composition done by adding polyvinyl, silicone, other additives to improve performance. Facade latex paint to obtain the release of OSV textured or dense, shiny, or matte propanamine.

Other water-based paints

In addition to the above-described water-based paints there are other types of water-based paints, which are successfully used in the external walls of the panels of OSB and not only. These paints can also be painted concrete and masonry materials before final finishing should be treated with sealers and primers. Aqueous paint emulsions are:

  • silicate paint, the main component of which is liquid potash glass; these colors are endowed with the greatest possible resistance to the pair;
  • silicone paint, which are based on silicone resin and a fungicidal additive, after drying not pass water and repel street dust and dirt.

Features staining

Oriented strand Board product is a special material, so its finish is also necessary to approach not so standard. The main working surface it is smooth, can be completely smooth or a bit rough. But the edges before finishing works it is necessary to process a special tool to make them somewhat rounded. In addition, the edges are more porous, so the pigment will be absorbed in larger quantities and get a great color from the main cover. To eliminate this issues will help putty for exterior works. If it is to carefully seal all joints and seams using serpyanka, then primed, then painted the plane will turn smooth and silky.

It is fair to say that primer is needed to cover all the outside walls and not just the joints. It will help to better adhesion of the dye with the panels and the OSB will serve in the role of antiseptic, that is, protect the walls and the whole house from any kind of harmful effects from weather and air. If during the installation it suddenly turned out that the defects, irregularities in coating. Or just suspect that through the coating can be viewed shavings, then you must also proshpaklevat facade completely. For outdoor work the paint should be applied to plane wood not less than two times.

For best visual result and a more durable surface, the external walls should be painted three or four layers, waiting for the complete drying of the paint on each of the layers.

Color options and features of the application

About some features of the external walls of OSB panels mentioned above. Now we need to discuss the best way to paint treated filler facade. In General, the main methods of staining of any of the planes and all coloring compounds, there are three:

  • with the help of atomizers or spray guns. Method is quite effective for obtaining a completely flat and durable surface. The dyeing process of this equipment does not take much time, but increases the consumption of dye against a standard. In addition, tools are expensive, buy them to paint one house unreasonable. Another disadvantage is the fact that a spray gun outdoors can be used only in the absence of wind, in very calm weather, with only a respirator;
  • as the main tool used paint brushes flat and round in different sizes. This method is the most trivial, but laborious, and time-consuming;
  • the third and, perhaps, the best method of staining the walls of the house outside is the use of paint rollers. To speed up the process, rollers are best to use wide. This tool allows you to quickly and efficiently painting large surface without loss of the coloring compositions. Suitable for any kind of mixtures.

The nuances of

For a start we will focus on the joints of the OSB boards. Treatment of these places putty brings a positive effect, but only briefly, because in the process of shrinking home plate can "play" and the putty may crack and fall out of the seams. It certainly will have a negative impact on the appearance of the facade. There is another way to design bottlenecks — the use of special covers. They close the seams after dyeing. These pads serve as protection of seams and design elements.

Paint work is convenient to start with the top of the wall that the paint is not dripping on ready baking circle. You also need to consider the weather conditions. Finishing work is most convenient to perform with a positive air temperature.

It should also mention that the painted facade of the OSB boards in the process of operation is unpretentious, but still requires some care. As a rule, facade materials highly resistant to external influences. Therefore external walls periodically need to wash using ordinary detergent, unless otherwise recommended by the paint manufacturer. It is undesirable to use brushes with stiff bristles, so as not to damage the finish.
