A gypsum ceiling board - more commonly known as drywall - is an excellent material to use when building interior walls and ceilings and is far simpler than its out-dated counterpart; plaster. There are no liquid-based materials to create extensive mess and gypsum boards are available in all manner of convenient sizes. This article covers the basics of using these gypsum ceiling boards in order to successfully re-model the interior of your household.

Step 1 - Important Measurements

To begin, use your tape measure to measure the ceiling by using a wall that is perpendicular to the joists. When you have done this, measure from the middle of the joist that is closest to 8 feet away from the wall. This will show you the starting point for laying your gypsum ceiling boards.

Step 2 - Custom Gypsum Boards

Take your razor knife and shorten a piece of gypsum board to this exact length. Use the t-square whilst scoring the length of gypsum board in order to ensure that your cut is completely straight. Next, set up the two stepladders so that there is one by the wall from which you measured the joist - and one in the middle of the room where the other end of gypsum board will rest. Position the board so that the cut end faces the wall. This way, flush gypsum board connections can be achieved in the middle of the room's ceiling. Your assistant must help to hold the gypsum board against the ceiling.

Step 3 - Screwing Them Up

Take your screw gun and fix drywall screws into the edges of the board every six inches, making sure that you only do this when underneath a joist or it will not hold properly. The room will be incredibly unsafe if the ceiling is constructed with this level of carelessness so ensure you plan correctly. It will not be hard to judge the position of the joist as you can follow their length from behind each side of the gypsum board. When attaching later boards, you will be able to fix screws parallel to existing ones in order to ensure you properly screw into the joists. Lay them end to end in a neat, professional manner. Ensure the screw heads push beneath the surface of the gypsum board.

Step 4 - Seams Simple Enough

Next, smother the seams between the gypsum boards with your drywall tape. Then spread with joining compound using your drywall knife. Feel free to use joining compound to cover sunken screw holes. The drying time for this procedure is around four hours. Use your drywall sandpaper to smooth over all of the dried joining compound. A second layer of compound must then be added, following the same technique before applying an extremely thin third layer. After this has been dried and sanded - you can begin painting your new gypsum board ceiling.
