How to paint OSB plates

All-purpose cleaner, bucket + sponge
Brush and tack cloth
Emery cloth 150
Large paint tray, fur roller 30 cm and latex
Synthetic flat brush, felt roller and acrylic primer


Osb boards are boards of pressed wood, but made of wood chips. During the pressing, a kind of glue or binder comes through which makes it all much more compact. The advantage of Osb is that you can reuse it again. Application: walls, floors and subfloors with a high insulation value. Plywood is made from compressed wood layers. If you have ever seen a plywood sheet you can see those layers.


Degreasing is the first step. Then dry well and then sand with 180 grit emery cloth. We use emery cloth to sand away the protruding splinters and the rest of the unevenness. Then remove dust and use an acrylic-based primer. When the primer has dried well, apply at least 2 layers of latex. Use a good quality for this. Otherwise you have to apply several layers which is labor intensive. Alternative for indoor use: apply glass fiber wallpaper to the panels. With this you no longer see an Osb structure and you can just start sauce.


For outside there is another method of treatment. Osb plates attract moisture and you have to exclude that moisture. Start impregnating so that you keep the moisture out. With this method you can still see the light color of the plate. Pickling is a second option. Stain is moisture regulating and you can have it made according to color. Make sure you apply at least 2 layers of stain. Maintenance: apply a new layer of stain every three or four years if the layer is no longer intact.
