Best paint for osb floor.

There s no such thing. Osb will swell warp and degrade unless it s kept safe from sunlight and perfectly dry. 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. 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 engineered wood association known as apa notes that exposure 1 osb can be painted. In kitchens or at doorways with water snowmelt. 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. 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.

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. 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. It ll be subjected to the ordinary abuses of a woodworking boat building shop. With a weather resistant barrier like tyvek over the osb and then cover that with siding of some sort.

No paint will do this. 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. The floor of my new shop is advantech osb.
