The engineered wood association known as apa notes that exposure 1 osb can be painted.
Best paint for osb floor.
If you want to use osb to sheathe the walls of your shed you need to build those walls like the walls of a house.
There s no such thing.
In fact due to the problems that edge swelling creates underneath a finished floor a couple of national ceramic tile associations have discouraged the use of osb as a subfloor or underlayment.
It ll be subjected to the ordinary abuses of a woodworking boat building shop.
Osb or oriented strand board is an engineered wood product often used as sheathing in walls floors and roofs it is cheaper than plywood and with no internal gaps more rigid.
The apa also notes that due to the prominently visible nature of osb s strands it will show through on one coat of paint a heavy primer may be required.
In kitchens or at doorways with water snowmelt.
That said you can do something similar with plywood stain adding thin router lines for a plank look.
With a weather resistant barrier like tyvek over the osb and then cover that with siding of some sort.
You can apply virtually any type of topcoat on osb but it is best to start with a primer that will block the transfer of moisture that can cause the panel to delaminate.
Osb will soak up water and never dry out so lots of sealing needed esp.
I m undecided whether to finish it with good old alkyd porch deck paint or one of the solvent based two part epoxies like rustoleum epoxyshield.
No paint will do this.
Oriented strand board consists of several layers of wood particles that are bound by an adhesive and compressed tightly together into a 4 by 8 foot panel.
The apa s main reservation is that osb shipped with a thin wax coating would inhibit painting.
