I bought a piece of drywall(48x26 inches) and ready to install it. Please see the images.
The height of the ceiling is about 11.35 foot. I tried to hold it with my hand, but it is heavy. I can't find a helper because the ladder only supports 250 lbs.
Please recommend tricks and tips.
Also I bought Black$Decker 5.2 amp 3/8 drill/driver. I am not sure whether I got the right tool and how to use it for mounting the drywall.
Should I use it drill holes on the drywall before installation?
The old screw likes below.
And do I have to drill holes on the wood with this tool?
