Can you use this on a osb sub floor


I've used it on sealed OSB in two rooms and it worked great. I don't like the way it spreads but there aren't many options for OSB.

Thank you for posting your inquiry. DAP Flexible Floor Patch and Leveler is recommended for use on plywood subfloors or concrete surfaces. OSB as well as pressed board, particleboard, MDF and similar "engineered wood" materials are not a recommended application surfaces.
