How To Install Plasterboard
It is best to hang ceilings first. If you hang the wall sheets first it reduces the amount of "play" you have in the length of the sheet therefore increasing the chance of jamming the sheet as you lift it up.
If you have no cornice and intend to have a square set finish then hanging the ceilings first is a must. It is easier to lift up the top wall sheet to fit hard up to the ceiling sheet, than to cut the ceiling sheet perfectly to size and lift it into place. Note, never measure tight, always measure accurately but allow 8 to 10 millimeters to play with.
Cut all the sheets and put them in position in the rooms before you start fixing. Place them on the wall where your first sheet will go up face out. If your room is not square put the shortest sheets in the room first then the longest, so the longest sheet is the first to put up. This makes it easier to check out the piece where the room gets smaller. Also by setting the room up this way you will not need to turn any sheets around.
Hanging ceilings by inexperienced people can be difficult if not done properly. The best thing to do is hire a sheet lifter, as in the picture on our home page, but for those that don't have access to a sheet lifter here are some useful tips.Your scaffold height should be set to the tallest person. His head should just be able to touch the ceiling. It would be preferable if the tallest person was to put in the first nails or screws, as he can reach out to the join easier. The scaffold should be set up slightly off center toward the last sheet you put up. This is because the fist fixing is going to be on the join of the last sheet put up. You start with the sheet leaning against the scaffold on the side away from the last sheet put up with the face toward the scaffold. You reach down and pick up the sheet together, (timing is important so you don't jam the sheet on the wall), rest the sheet on your toes until you are ready. Lift the sheet over your head, (again timing is critical to avoid jamming), The tallest person should take the lead and place his end of the sheet into position first. The shorter person should keep his end down lower until the other end is in place. Then both push the sheet up into position.
The first fixing should be about the 3rd or 4th batten/joist back from the end and on the join. Don't nail or screw the first 3 fixings all the way, the next fixing will be in the middle of the sheet on the very end, with the next on the outer edge of the sheet on the same batten/joist as the first. Provided these fixing are not fixed all the way, they will hold the end of the sheet up. Now you can start moving down the sheet toward your partner, go from join to outer edge until there is no sag in the center of the sheet. Then your partner can start fixing his end. Last of all fix the center of the sheet. NOTE, if your first fixing go all the way home, you will need to put more fixings in that end of the sheet before you can move back toward the center of the sheet.
As a matter of interest a 6m long sheet can be held with 6 nails providing they are not driven home!!
