Will it work on OSB , which is my subfloor ?


We do not recommend the use of DAP Flexible Floor Patch and Leveler on OSB (Oriented Stand Board) as it is not classified as an underlayment grade substrate.

Yes it will work just fine. I used it to fill in a low spot in OSB that was caused by damage from a Jacuzzi, it worked out great and yes the Jacuzzi was in my house. I have carpet over the OSB sub-floor. This works good for cracks, holes, and filling in low spots. Make sure you have a trowel and something like a level or straight board to spread it evenly. It works as well or as the same as it does on plywood.
