Instructions: How to paint OSB boards with paint
- 1) The preparation
- 2) The painting begins
- 3) As a high quality floor covering
Like many other things OSB plates from America have spilled over to us. The building material that is so popular today is attractive, inexpensive and easy to work with. The chipboard can be used both indoors and outdoors. With a matching coat of paint you can paint OSB boards and provide them with an individual touch.
The simple look of the so-called chipboard can give you a fresh boost with a little color. According to your taste, the building material made of wood as a wall or floor covering becomes an interesting design element of your rooms. There are only a few things to keep in mind when editing this material. Similar to classic wall paint, give the coarse chipboard a matching look with an authentic look that can range from distinctive wood tones to fully opaque colors. Here is the advantage of the OSB board: It can be embellished with various paints and colors. And even the industry is responding to the trend of coated OSB panels and has already developed special colors.
1) The preparation
Outdoors, coated OSB panels are ideal for protecting the material. They usually can not be painted because sanding the surface would destroy the coating. Inside, however, uncoated panels suitable for painting are used. Select uncoated material when buying the coarse chipboard. On the other hand, it is difficult to apply the color durable. At the same time, the desired effect can not be achieved with a coated plate. In addition, each panel must be sanded before painting, so a possible coating would be damaged here.
After the untreated chipboard is at home, they are ground and prepared with a barrier primer for painting. However, before you begin sanding and priming, you should give the plates about 48 hours to acclimatise. In the process, any moisture or ambient moisture in the material is released. It is important, of course, that the individual plates lie on each other at small intervals. You can put small pieces of wood between the individual layers.
For shopping, think about the following things:
- choose uncoated plates
- abrasive paper
- small wooden blocks for storage and acclimatization of the
- the desired wall paint, floor paint or stain
The necessary barrier primer
A barrier primer prevents the surface from absorbing the respective protective coating. In the case of the coarse chipboard, a paintable primer should be selected. The coarse chipboard is still a wood product and its typical properties. This allows wood to bulge outward in conjunction with liquid. For example, if the panels are used indoors as a floor covering, the fluid will cause an uneven surface. The primer is therefore necessary for the quality and life of the OSB board in any case. In the interior of a home-made wardrobe is suitable after priming a good wall paint without the intense odor nuisance through paint.
Tip: Select already when buying on uncoated coarse chipboard. Do not forget the primer when shopping!
The choice of color
The choice of color depends on the purpose and use of the OSB boards. As a floor covering in the outdoor area, for example, a solvent-based paint is needed. A water-based paint is less suitable for painting because the material may warp. Even a complete seal is possible.
2) The painting begins
The primer is now dried. Now it goes to a pre-painting. Pickling is also possible. In order to prevent possible discoloration of water components as with a wall paint, you should select a solvent-based product for the painting here. The first primer may develop an intense odor. However, if the second layer is applied directly after drying of the solvent-containing products, such odor formation can be prevented. For the primer, you can choose to work with a roller or a brush. Even a spray paint is conceivable. The paint itself should be applied thinly and evenly. With additional layers, which must first dry out, you increase the opacity of the color.
Note: When painting indoors, always ensure good ventilation. So the smell of the color evaporates quickly. If possible, you can also move the painting to the outside of the house, but avoid intense sunlight.
Also pickling is possible
Pickling offers additional advantages over the wall paint. On the one hand, the market offers a large selection of different wood shades, so that pickling can be understood more as painting than painting. Wood stain is usually available in liquid form and many natural wood tones. This stain is ready to use and can be applied immediately. The pickling usually leaves a very nice harmonic impression on the material and can be wonderfully integrated into the living space. Furthermore, the structure of the OSB panel remains visible after painting. The individual chips absorb the color pigments differently, which in the end result is very appealing. Even when pickling, the plate must be ground in preparation. The resulting dust residues are carefully removed with a brush. You can paint the coarse chipboard several times to get a darker effect of the color. Finally, the surface should be treated after drying with a glaze or paint to protect the surface.
Pickling at a glance:
- Wood stain is available in many nuances
- in liquid form, the paint is ready for immediate use
- Repeated stroking makes for a darker tone
- indoors and outdoors
- a final coat of paint protects the surface
Tip: Make a pattern before pickling by applying all scheduled layers. So you see the end result and can possibly make changes in the hue.
Use paint in combination with stain
A paint also ensures that the color appears fuller. The commercially available one-component clearcoat is very well suited here. You have the choice between semi-gloss or high gloss. The high-gloss paint requires a skilled hand for even application. The application works very well if you apply the paint with a solvent-resistant synthetic fiber roller. So you can be sure that the paint is applied evenly and creates a nice surface. But beware with high gloss! A high-gloss surface also has disadvantages depending on usage. If the surface is used, for example, as a floor covering or tabletop, scratches can be quickly recognized after a while. Silky matt, however, looks natural and full. When painting with varnish, you should plan drying times of approx. 12 hours per varnish layer. Plan such work for the spring or the beginning of summer, when at the same time good ventilation favors drying.
- Always apply varnish in thin layers
- Choose high quality brushes that will not lose hair when applied
3) As a high quality floor covering
With a traditional floor seal on linseed oil base you get a very attractive as durable floor covering. With the usual first steps of sanding and a primer, the floor seal is applied twice. It is also important that you let each layer dry well before re-application. Such a coating is the ideal alternative for every interior of the house.
Tip: hurry with time! Allow sufficient time to apply the different layers.
The seal with the special OSB paint
Before the first coat, the sanded surface must be free from residues, oil or wax. As a primer, the OSB paint is diluted to 20% and applied. Thereafter, the surface must be allowed to dry for 12 hours with sufficient ventilation and lightly sanded again. Then another diluted layer follows at 10% of the paint. Be sure to apply a thin layer of paint evenly on each coat. Finally, another third layer of varnish takes place. After drying for a further 12 hours, the sealed floor offers very good protection against water, grease or household cleaners.
Notes on sealing:
- Apply each coat in a thin layer and let it dry for at least 12 hours at room temperature
- The first two layers are applied diluted
- After each layer, lightly sand the surface for good adhesion
- Use fine sandpaper for sanding
- Always clean the surface well before re-applying
Tips for quick readers:
- For painting, buy untreated OSB boards
- For indoor use, select uncoated panels
- Use outdoor coated panels
- Cover OSB panels with a barrier primer
- Little water when working with wall paint
- Sufficient ventilation reduces odor nuisance
- Sand the surface after the first coat
- This is followed by another coat of OSB board
- Use fine sandpaper
- Select brush in good quality to prevent individual hair
