Osb will swell warp and degrade unless it s kept safe from sunlight and perfectly dry.

Best paint for osb floor.

Manufacturers of osb often cover it with a water resistant film and add borate compounds to the wood making it toxic to insects like termites and wood boring beetles. The engineered wood association known as apa notes that exposure 1 osb can be painted. 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. 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.

Osb will soak up water and never dry out so lots of sealing needed esp. No paint will do this. 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. 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.

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. That said you can do something similar with plywood stain adding thin router lines for a plank look. It ll be subjected to the ordinary abuses of a woodworking boat building shop. 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.

In kitchens or at doorways with water snowmelt. The apa s main reservation is that osb shipped with a thin wax coating would inhibit painting. There s no such thing.
