I was thinking of getting some tips,,, I have an upstairs with a sloped ceiling where OSB is on the studs. I bought a 6 mm MDF panel that I plan to use as a surface layer. Can I nail the MDF board onto the OSB? I was thinking of gluing a bit on the backside as well. My idea was to use 15mm brads (MDF 6mm, OSB 10mm) if this is possible, any tips on a brad nailer? Or am I way off, has anyone done this? Grateful for answers.
