Ditto...To "get it RIGHT" you need to use a drywall screw gun set to the
PROPER depth and drive the screws STRAIGHT in and NOT cockeyed...DO NOT use
a cordless driver that MOST carpenters and homeowners TRY to use...It ALWAYS
creates problems with screw pops due to over driving screws....Dimple any
missed screw holes in by GENTLY tapping them with the handle of your drywall
knife..That is what the steel end cap at the bottom of the handle is
I've seen nail pops but never "screw pops".
Most nail pops (imo) are from the drywall not being seated against the
framing, timber shrinkage or nail not being seated / dimpled
Pops come from relative motion between the nail (screw) head and
drywall face sheet / mud / tape. In order to a "pop" (nail head
pushes "out" on mud / tape) to occur either the nail must move
"outward" or the drywall "inward" or similar relative motion.
I see this as being highly unlikely with screws unless the drywall was
not seated against the framing.
Drywall is pretty crappy material.
If you pierce the paper, it is my understanding that it can cause 2
problems. The loose paper above the screw can let the mud above it pop out.
Nail pops are not necessarily a nail popping out. Loose paper can look the
same according to a sheetrock guy I used once in my previous home. Also if
a lot of the screws pierce the paper the sheetrock will hang loosely on the
stud and if someone leans against it the screwheads can push out the mud.
Well it will pierce the paper, it has too. It should also
produce a small indent around the screw or nail head. Without the
indent the screw or nail would poke up above the surface of the wall.
Not good. With the indent it gets filled with dry wall compound.
It won't make a bit a difference, since he glued or PL'd the studs b/4
hanging. Uhhhhhh, that's providing he glued or PL'd the studs.
I wouldn't think about putting a covering such as Corian over _unglued_
rock, unless you like asking for trouble.
Just buy this guy some 50 cent "dimpling bits" at home depot and shoot
some more screws. The dimpling bits work great, they release the
screw just as it dimples the paper without tearing it. Or just shoot
more screws yourself while he is away. The paper should not be torn
to get the most strength. Also if it's a wet area you should be using
stainless steel screws anyway.
