Consequently, what kind of paint do you use on OSB?
If your OSB panels are used indoors, an acrylic latex primer will be an ideal base coat because it's so easy to work with. Latex primers are fast-drying, so they can be painted over in as little as an hour.
Subsequently, question is, can OSB be stained? OSB (oriented strand board) is similar to plywood and used primarily for subfloors, covering exterior wall studs and roofing. It is not usually stained or painted, but that doesn't mean that it can't be done. OSB used for interior and exterior projects will accept stain and clear coat sealing products.
Consequently, can I paint OSB for exterior use?
Seal both sides of the OSB and the joints with a quality waterproofing primer. Paint the OSB with two coats of a premium exterior topcoat. Use a topcoat that will stand up to the weather in your area. OSB will fare much better when painted with a paint that protects it from the elements.
Do I need to prime OSB before painting?
Yes, OSB can be painted. Because OSB does not sand down smoothly, you will not be able to bring down the texture with sanding after painting. Priming Will Be Required: While priming may be optional with some surfaces, it is absolutely necessary to apply primer before painting OSB.
