Most new homes at the beginning have a lot of drywall nail pops.this is when the head of the nail pops out or the plaster pops out from the head of the nail. This could be cause by faulty initial installation, some external stress on the wall, or loose panels. Probably the biggest cause of nail pops is because the lumber is shrinking behind the drywall. Pops usually occur several months after they had been completed. To fix nail popping remove any loose gypsum and torn paper from around the screw press the panel firmly against the stud and re-screw a new screw into a fresh part of the drywall 1 1/2 inches above the original hole and 1 1/2 inches below the original hole. Make sure that you don’t break the paper driving the screw in. The screw should go in just far enough that it dimples the drywall a little. And when you pass your plaster over top of it, it should be nice and smooth.
In most instances probably you have half-inch drywall you should use a 1 1/8 inch drywall screw.
If you’re nailing the drywall double nailing everything. I find nails are more prone to loosening up. And don’t forget blow with a hammer the nail head in with just enough force to create a small dent in the drywall being careful not to break the paper because this will greatly reduce the effect of the nail.
Quick Note: I always do my repairs with drywall screws not nails.
When you’re finished screwing a panel up check to make sure that all your screws are the same level and holding the drywall securely. If you have a couple of screws that are still above grade, take your screw gun and re-torque them to the proper depth. Electric drywall screw guns are adjustable for depth as you screw in the head of the electric screw gun the deeper the screw will penetrate so this way you can adjust the depth of the screw by rotating the head of the screw gun.
Bulge:
in your drywall:around the fasteners. This can be caused by driving in the fastener to deep in. In this case when you put plaster over top of this it will tend to swell creating an unsightly bulge. It is better to simply remove the fastener and install to fresh fasteners one above one below.
Sagging Drywall
Your ceiling could end up sagging after a few months. This could be caused by excessive weight of insulation or texture mix on your ceiling. Also there might be too much moisture or humidity in the air. It is also possible that the initial installation had used the wrong thickness of drywall. Consider using a thicker drywall or double screwing or nailing it up.
Preparing Holes in Drywall
If you have any holes in your drywall moving furniture or some other kind of damage the best way to fix this is remove any loose paper that is either bulged out or hanging, inspect the damaged area to make sure that there has been no drywall pushed up into a bunch causing a lump higher than the drywall. Everything has to be below grade to be able to be plastered over top of without making any hump in the drywall. If you have some exposed paper (this usually is a dark brown paper) it’s best to peel it off if it’s loose and if not then it’s advisable to seal it with some shellac or some kind of primer sealer. This will stop the paper from bubbling up when the wet plaster is applied to it.
If you’re still having problems not being able to hide wall repairs and you just can’t figure out why it is so showing up or your drywall boards are still loose then Toronto painters will be able to fix this problem for you.
