Yes, you can put epoxy on OSB (Oriented Strand Board). However, it is important to ensure the OSB is clean of any dirt and surface films, dry, and free of deflection. If the floor is not structurally sound, it may deflect when a car is driven over it, and in those cases, you need a flexible epoxy that has more flexibility than a standard floor epoxy to prevent cracking. Please contact us for building a system for you with a flexible epoxy. We also strongly recommend that you use a primer such as our Epoxy Bonding Primer on OSB applications to ensure proper adhesion.
