What kind of paint do you use on OSB?
Acrylic Latex Primers 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. They are nearly odor-free and do not contribute to indoor air pollution.
Is OSB waterproof when painted?
OSB is highly resistant to moisture and can be water and weatherproofed for exterior use using good quality paint or stain. It has superior strength to other wood panels and a slower rate of moisture absorption.
What is the best way to paint OSB board?
Using oil-based paint is essential. Just painting the OSB like you would paint plywood will leave the OSB rougher and the paint will bleed through regular primer, while using water-based paint causes the OSB to peel over time, making it look unattractive and requiring regular maintenance.May 1, 2010
Will painting OSB make it waterproof?
A good exterior paint can actually add to your OSB's water resistance, as well as add a splash of color to your project. If you intend to paint your final project at all, make sure it is added before any waterproofing so the sealer can also protect your top coat.Apr 30, 2010
Can you spray paint OSB?
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.Jul 28, 2017
