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.
Commercial: Hang the drywall vertically. Hides uneven studs – Hanging horizontally also allows the drywall to flow over the framing so that bowed studs create less of a problem. If the drywall were hung vertically and a seam placed on a bowed out stud, the seam would be magnified because of the bump in the wall.
Secondly, should drywall touch the floor? Drywall should definitely not touch concrete as moisture will wick (ie flow up the surface as in a candle/lamp wick) into the drywall and encourage mold growth. 3/8″ should be sufficient – your prop up plan is not only appropriate, but a common technique used by drywallers.
One may also ask, what is between horizontal and vertical?
The terms vertical and horizontal often describe directions: a vertical line goes up and down, and a horizontal line goes across. You can remember which direction is vertical by the letter, “v,” which points down.
How much drywall can man hang in 8 hours?
Each man should be able to hang 35 to 40 sheets an eight hour day.
Does drywall have to end on stud?
Keep in mind that all pieces of drywall should begin and end on a stud. You should never have a piece of drywall overhanging a stud, or two pieces of drywall meeting in the open spaces between studs. If your stud walls were properly constructed on 16″ centers, you should have very few problems with this.
How far should drywall be off the floor?
Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.
Should drywall joints be tight?
Drywall Joints Are Too Tight Not only that, but you have to allow for expansion and contraction of the underlying framing members. Natural seasonal expansion of the wood framing can crack drywall joints that are too tight.
How far should drywall screws be apart?
Field: 16 inches apart Both the International Residential Code (IRC) and USG, the manufacturer of Sheetrock, say that maximum field screw spacing for wall drywall is 16 inches. Some builders like to space fasteners tighter than that, so they go down to 12 inches.
How many coats of drywall mud do I need?
Apply three or more coats of very thin compound rather than one or two heavier coats. Yes, it takes time for the compound to dry, but don’t try to rush the drywall taping process along by applying fewer, thicker coats.
Do you hang drywall top to bottom?
When hanging the drywall on the walls, always hang the top sheet first. Raise a sheet tight to the ceiling and secure it with a drywall nail at the top and bottom at each stud. Complete the top row throughout the room before proceeding to the bottom.
How many screws go into a sheet of drywall?
Drywall screws per sheet. Drywall screws should be installed every 12 inches. This means that when using 48 inch wide sheets, you will have 5 screws in each stud when the sheets are hung perpendicular to the framing; two on the edges and 3 in the field.
What thickness does drywall come in?
Drywall comes in sheets. While the most common size is 4 x 8 feet, you can purchase much larger lengths. Use a sheet size that minimizes the number of seams that will appear in the finished product. Drywall comes in various thicknesses, 3/8 inch and 1/2 inch being the most common.
Where do you start when hanging drywall?
Begin installation in the opposite corner of the room in order to offset the vertical seams from the top row to the bottom. Drywall has the most structural strength if these vertical seams are offset by at least 4 feet.
How long does it take to drywall a house?
Drywall installation takes as little as one day and as long as four weeks, including the time it takes to prep and clean up debris. The amount of time depends on the size of the project, framing needs, and level of finish.
Why do nails pop out of drywall?
Drywall nails pop out because they are nails. They have smooth shanks, and any stress caused by movement of the framing can loosen their grip. A series of popped nails on a wall often signifies truss uplift or foundation settling.
