Sheetrock is a generic brand of drywall, which is used as a wallboard, or plasterboard. Sheetrock is also available in some countries as a trademarked product of the U.S. Gypsum Company and installed in many construction projects across North America.
There are also different types of sheetrock: Regular, Heavy Duty, Lightweight, and Fire Retardant. However, what type you need will depend on the situation that you’re working in. For example, if you’re installing it within an exterior wall to keep the rain out there would be no point using fire retardant sheetrock because such material would not be needed. “A piece of sheetrock is commonly cut using a circular saw. If you have no other choice than to use the hacksaw, it would be best to secure the board into position by screwing it onto plywood or another piece of wood that will provide enough support for the sheetrock cutting process.”
Screws should not be visible on the finished surface. They should be countersunk, and if they are too visible a small piece of wood can be cut to cover the screw head. Countersinking requires the use of an adjustable drill bit.
It’s best to avoid using nails because they will make it difficult at a later date if you decide to install additional devices on the wall such as lights or shelves. If you do use nails, make sure that they are the proper type for sheetrock installation (not drywall), and use an appropriate fastener size.
