About a week ago I re boarded a ceiling with 9mm 8x4 sheets I used 3 inch wood screws to fix as I ran out of drywall. The heads are bigger on the wood screws than dry wall so just thought it was a bonus. I positioned the screws eaqualy in rows of 4 along the width. Approx 32 screws in each board. It's a large ceiling with about eight boards. I then taped the joints and gave it two coats of plaster using x4 bags. Today without any warning the lot came down leaving the screws in the ceiling..... Any thoughts please?
