Can you paint directly onto OSB board?

The Engineered Wood Association (known as the APA) acknowledges that you can successfully paint "Exposure 1" OSB. Still, their central reservation is that OSB has a thin wax coating that protects it against moisture and inhibits painting.

How long will OSB last outside of painted?

For exterior applications, if you are not painting the OSB directly after installing it, be aware of how long you have before the material begins to be affected by the elements. For example, Weyerhaeuser Edge Gold OSB panels are warranted for 200 days against edge swell caused by water absorption.

Can you use water-based paint on OSB?

Use an exterior water-based paint for best results. Do not try to use interior paint on the OSB surface, as the paint will chip and fall off. Use a paintbrush to paint the trim and corners. Paint the rest of the surface with a paint roller, applying an even coat.

Can OSB be spray painted?

No. If the customer is acting cheap by putting OSB on something and wanting you to spray it smooth with the idea that it'll look like MDF or something, then forget about it. Time to move on or educate them some. The stuff is very porous and you'll probably end up putting a primer and 2 coats of paint.

How long does it take to Prime an OSB board?

After the resin has dried (about 20 to 30 minutes), sand down the board and the edges. You may need to repeat this cycle four or five times before all of the texture has been smoothed over. Once the OSB is smooth enough to your satisfaction, prime it twice. After the last primer coat has dried, apply the paint.

What kind of primer should I use on OSB?

I guess the most bomb proof solution would probably be an oil based primer and then a satin gloss but that would get really expensive. I have looked through the internet and come across lots of suggestions.

How many coats of paint do you need for OSB board?

OSB's open strands readily absorb paint, requiring two coats at a minimum but more likely three coats. Older OSB will be especially porous, requiring several coats of paint plus primer. Particularly old OSB that is beginning to fall apart cannot be painted; the paint will not help glue the OSB together.

Do you need to cut OSB before you waterproof it?

Therefore, you will need to make sure your OSB is cut into the pieces you will need before you add your waterproofing so these edges can be protected. Measure, mark, and cut all the pieces you need, and set them aside on the tarp. You don't want grass or dirt to get in your waterproofing either. Save a scrap piece of OSB at this time as well.
