Got a problelm with shooting finish nails into MDF. the nail sinks below the surface, but a nickle-size bump grows around it. my pressure is set to 90psi (i’ve tried higher and lower) and i am shooting into either wood or drywall behind the moulding -both give the same result. thanks for your consideration, T

up the pressure anothe 10 pounds... shoot the nail... shave the bump off with a sharp chisel...
quit using MDF...

Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming
WOW!!! What a Ride!
buy a hitachi finish nailer.
You need to use a brad nailer which will minimize the hump. Then shave the hump with very sharp chisel or plane. BTW, this shaving will change the surface texture and accept paint differently. Be sure to sand area after priming.
