It was made by layering plaster within four plies of wool felt paper. An alternative to traditional wood or metal lath, it was a panel made up of compressed gypsum plaster board that was sometimes grooved or punched with holes to allow wet plaster to key into its surface. As it evolved, it was faced with paper impregnated with gypsum crystals that bonded with the applied facing layer of plaster. Vertically hung drywall with joint compound. The board is then formed by sandwiching a core of the wet mixture between two sheets of heavy paper or fibreglass mats.

A good idea is to run masking tape along the floor while you have the studs exposed and mark the center line of each stud with a high visibility marker. When cutting drywall, use a T-square and razor knife to score a line on one side of the drywall paper.
Place your knee on the opposite side of the cut and quickly pull the drywall piece towards you while at the same time pushing your knee outward, snapping the drywall in a clean line. Clean up the remaining paper along the newly formed crease with your razor. Do this right before you intend to hang the drywall. Start in the center and work outwards. Drive in five screws for each stud. Extra screws may help in some situations, but are usually overkill; they will require extra mudding and sanding that may detract from the overall finish.
Consider using a spring-loaded drywall screw dimpler. They are designed to automatically countersink each drywall screw to precisely the same depth before ratcheting the screw bit, as a sign to quit and back off the drill.
Continue installing drywall over window and door openings. At the same time, be mindful that no seams line up with a door or window corner, and do not fasten panels to framing around openings yet. A good practice when installing drywall over protruding pipes is to place the drywall against the pipe and lightly tap with a flat block of wood to dimple the back. Next, pull the drywall away and use a drywall circle cutter or drywall hole saw to cut a perfect hole along the dimple.
This should be much easier to finish than if you punch out a large hole that requires coats of mud to finish. Start the next row at the edge of the wall, next to the previous row. Fasten the drywall down around the window or door, and then cut out the proper section using a rotary drill or drywall saw. Extra screws put too much pressure on the stud. Try another answer Extra screws need more mudding and sanding.
Read on for another quiz question. Extra screws get in the way when cutting around irregular openings. Not exactly! Look for another reason to stick to five screws! Guess again! Extra screws might split the drywall panel. Try again! This is not the main reason to avoid using more than five screws. Keep looking for a better answer! Want more quizzes?
Kahn This is motion above that caused by expansion of metallic penetrants due to heat exposure in a fire. Drywalls are easy to put up and need less labour, to be precise, drywalls can be executed 3 to 4 times faster than masonry construction. These offer superior moisture resistance properties and also the flexibility to fix: During such incidents, some or all of the drywall in an entire building may need to be removed and replaced. Recycled paper is typically used during manufacturing. This is also often the point of failure of the wall in terms of leakage of sound and fire. Some manufacturers take back waste wallboard from construction sites and recycle it into new wallboard. The board is then formed by sandwiching a core of the wet mixture between two sheets of heavy paper or fibreglass mats.
