Position your first sheet. For the ceiling, start in a corner with the panel tight against the walls. For walls, place the sheet tight against the ceiling and against one wall.
Always do the ceilings first, no matter what. You are dealing with weight and gravity so the walls hold the ceiling board firmly in place and helps prevent cracking in the corners. Make sure you put in at least 5 screws across the board and 6 at the butt end to also help prevent any movement.
Tip: For easier installation it is recommended to install the plasterboard ceiling before lining the walls. Measure the wall to determine the required sheet size.
Drywall is typically installed starting at the top for several reasons: Gravity and Weight Distribution: Installing drywall from the top down allows the weight of the sheets to rest on the lower sheets. This helps prevent sagging and ensures a more stable installation.
Ghosting happens when mildly damp, warm, and possibly sooty interior air condenses on the sections of walls and ceiling that are colder because part of the wood frame is uninsulated. This results in black sooty stains on your walls and ceilings that follow the patterns of your home's framing.
If you see a gap between your walls and ceiling, you should call a crawl space and basement repair expert immediately. At The Drying Company, we have the resources and expertise to repair separations and fortify your home.
Keeping the joints between sheets of drywall too close is an invitation for troubles along the way. Professional drywall installers allow for ⅛-inch space between sheetrock placement, and this allows for expansion and contraction for the frame of the building, avoiding cracks and damage to the drywall.
Top-down construction allows for the drywall trade to install the nonstructural cold-formed steel framing and the gypsum panels that will be above the finished ceiling plane. This assures proper placement of framing and the use of whole sheets of gypsum wallboard.
One key difference between the two is that sheetrock is a brand name of drywall made by the United States Gypsum Corporation. Another difference lies in their production process; sheetrock has a slightly denser core than drywall due to the addition of a small amount of wood fiber to the gypsum core.
Always cut in first then continue painting with a roller. Cut in and paint with a roller one wall at a time. If you cut in all areas first and then roll the entire room, the paint that was applied when cutting in will have dried quicker and you will be left with a patchy, uneven finish.
Number of Screws Per Sheet of Drywall
Use about 32 drywall screws per sheet of 4-foot by 8-foot drywall installed horizontally on a wall. This total is comprised of four screws on the five middle studs and six screws on each of the two sides.
Commercial: Hang the drywall vertically. On commercial jobs, fire codes often require seams to fall on the entire length of the framing, so the drywall must be hung vertically. Residential: How high are the walls? For walls nine feet high or shorter, hanging the drywall horizontally has a number of benefits.
Adding glue won't increase the strength of the drywall, and it can make it much harder for you to remove and replace damaged drywall. Adhesive can bridge gaps, though, and it can keep temperature-controlled air from escaping or entering through the ceilings, making rooms more energy efficient.
This is a matter of prerogative and the nuances of your project. Drywall is usually done first as this makes things easier for the drywallers and results in a full angle showing on the ceiling. It certainly doesn't have to be done that way, though.
Hang the Ceiling First
This makes it much easier to manage and attach the panels since you will not have to fumble around with the screws, measuring tape, and so on. Screws for drywall lids should be placed no closer than 16” from the wall. This allows the drywall to have a bit of flexibility to prevent ceiling cracks.
Always leave a 1/2-inch gap at the floor.
All edges of all sheets of drywall must land on a solid surface such as a stud. A hanging drywall edge may work in the short-term, but in the long-term it can result in cracks and other serious wall issues. Sometimes, the drywall does not horizontally reach a stud.
If you use the double-drywall technique and put a further layer of sound-dampening material or compound between them, you'll have a quieter area. The added layer of drywall and compound reduces vibrations and (consequently) cuts down on the sound that travels through the walls.
After taping and smoothing drywall, wait one day to allow the mixture to dry overnight. Next, lightly sand off any bumps before applying another coat of mud.
Ultimately, staggered seams are stronger because the joints – the weakest part of the wall or ceiling installation – are minimized. Staggered joints are also less visible and easier to conceal for a flawless finish, offering a smoother, more professional look to the completed job.
A cornice is a type of moulding which runs along the top lengths of your interior walls, which sits in the join between the walls and the ceiling. Cornices are also commonly known as coving, or crown, bed or cove moulding.
One of the most significant advantages of using inside corner bead is the superior moisture resistance. Unlike paper tape, which can be susceptible to mold, mildew or failure if exposed to excessive moisture, vinyl inside corner bead is impervious to such disasters.
