On commercial jobs, fire codes often require seams to fall on the entire length of the framing, so the drywall must be hung vertically. However, on residential jobs, the drywall on the walls is typically hung horizontally. For walls nine feet high or shorter, hanging the drywall horizontally has a number of benefits.
It's generally not a good idea to use old joint compound because the hardener degrades with age and exposure to air leading to a "dusty" joint. It can also harbor mold spores.
Drywall isn't as durable as plaster, so it can't be left unpainted. With drywall, a coating of drywall joint compound (often called mud) is applied over paper tape at all the seams and at nail heads—not over the entire surface.
Left unprimed, drywall starts to yellow within a few weeks. The yellow will bleed right through most lightweight joint compounds and typical drywall primers, which is why it's important to prime right after drywall finishing is complete. When the primer is dry, you can paint with a regular latex paint.
New drywall construction requires the use of tape for the best results. However, if you're mudding a hairline crack in an existing drywall ceiling or wall, you may apply wet joint compound to the crack with a 6-inch taping knife, and smooth it flush with the drywall without using tape.
It's stored on it's side (beveled edge up/down) all the time on job sites. Just make sure to protect bottom edge and keep it off the ground if there's a moisture risk.
Once installed, drywall is fragile, easily damaged. Moisture can ruin it, making it a fertile breeding ground for mold and mildew. Good luck: drywall cannot be removed and replaced.
How do professional drywallers manage to finish in one day without having to come in multiple times? If you use a fast-setting compound mix, you can cover a lot of drywall in one day.
Drywallers earned an average of $41,620 per year and $20.01 per hour as of May 2011, according to the U.S. Bureau of Labor Statistics. Half of workers in this occupation reported annual salaries between $30,170 and $49,040.
The cost to install drywall is about $1.50 per square foot.
After material and labor are added in, the cost per panel can range from around $40.00 to $60.00. A typical 12x12 room, for example, will use 12 panels.The average cost to install drywall is between $1.60 and $2.35 per square foot. For a typical 12' x 12' room with a wall height of 8', the price averages around $815 for just the walls, or a total of $903 if including the ceiling drywall.

Re: Sheets Per Day
Each man should be able to hang 35 to 40 sheets an eight hour day.Estimate Drywall Sheets
Calculate how many drywall sheets you will need by dividing the total square footage of area by 32 (if you're using 4-by-8 sheets) or by 48 (if you're using 4-by-12 sheets). If you want to get the cost, just multiply the total number of sheets by the price per sheet.Across US homeowners report spending $1.5-2.2 per square foot to install drywall. This includes all materials and labor to both hang and finish the drywall, so that a contractor can paint it. If you have about 2,000 sq.
Pull out any drywall nails that have popped out and replace them with 1 1/2-inch drywall screws. Spread a coat of mud on uneven seams from which you haven't removed any tape with the drywall knife. Scrape the mud flat with the knife. Let the first coat of mud dry overnight, then recoat all the areas you are repairing.
How to Repair a Small Scratch in Drywall
- Prepare surface. Scrape the area clean and level with a putty knife.
- Apply compound. Put a small amount of light weight spackling paste on the putty knife.
- Finish scratch. Finish the small drywall scratch by using a sanding sponge to create a smooth surface.
Lightly sand the area with the damaged drywall tape using a drywall sanding screen. Then make a 1/8-inch deep cut around the perimeter of the bad tape with a utility knife. Peel away the damaged tape and drywall compound with a putty knife.
But hanging drywall is not just about speed. Installing drywall is easy enough for a homeowner, as long as there's someone to help; the heavy sheets are difficult to lift, particularly when doing ceilings.
A common reason for an air bubble to appear under drywall tape is improper installation. The bond between the drywall compound and the drywall tape is not adequate. You need to fix the air bubbles before finishing the joint, as ripples in the tape left unfixed would be evident after the wall is painted.
Lighter colors are more reflective than darker colors. Consequently, light-colored paint tends to reveal imperfections while dark paint tends to hide them. However, very dark colors can make a small room feel smaller and any room seem dreary.
The same procedure works on edges around outside corners that are too uneven to finish.
- Fill a gap wider than about 1 inch, either on a flat or corner seam, with a strip of drywall.
- Fill a gap less than 1 inch wide with patching compound.
