Frequently Asked Questions
Q: What is the proper direction to hang drywall? I have seen it done both ways.
A: The most time consuming and costly part of installing drywall is the finishing. The goal is to hang the drywall in the best manner possible to reduce the number of joints to finish. Drywall is available in various sizes. The most common are 4' x 8', 10', 12', and 14' sheets. Cost per square foot normally remains constant regardless of sheet size. Another issue to think about is handling and weight. You must consider all factors to decide what will work best for you.
Q: Is it necessary to tape the joints in the base layers of fire-resistance rated multi-layer gypsum board to maintain he fire resistance rating?
A: No. In multi-layer systems, the joints and fasteners in the base layers are covered and protected by the overlying layers of gypsum board.
Q: My home was in a flood and the wallboard in the basement was exposed to flood water. Do I have to replace the wallboard in my basement?
A: Yes, Wallboard that has been soaked by floodwater can be a permanent health hazard. When the wallboard finally dries, there will still be mud and contaminants dried inside and to the wallboard.
Q: Can water-resistant gypsum backing board (green board) be applied to ceilings?
Q: What types of tape and taping compound should be used with fire-rated drywall?
A: All purpose joint compound with paper or fiberglass tape will meet your needs.
Q: Can gypsum plaster be applied directly to wallboard?
A: No. Gypsum plaster will not properly bond to wallboard face paper. Gypsum Lath must be utilized when a board product is specified. Gypsum lath has special absorptive face paper designed to permit a strong plaster bond. Note: Wallboard back paper is not lath face paper. Do not reverse wallboard and plaster backside of wallboard.
Q: I am finishing my basement and have a lot of boxed in duct work that I am drywalling. Can I use two rough cuts (rather than finished edges) at the corners along with corner bead?
A: Yes, the corner bead should allow enough fill area to finish corners.
Q: Do I have to remove the old plaster or can I use wallboard screws to put sheetrock over the existing plaster? All the studs have been located visually.
A: You can sheetrock right over the old plaster. Just recognize and plan for the extra width of the walls in the door jam and window framing areas.
Nails In Plaster
To avoid splitting a plaster wall when driving a nail into it, try heating up the nail first. The hot nail will go through the plaster easier and without any cracks!
Finding A Wall Stud
Ever wondered how to find a wall stud when you want to hang a picture? Wall studs are usually 16 and 18 inches apart. Tap the wall gently with a hammer. The change in sound will indicate the presence of a stud.
Tearing Down A Wall
First check your load bearing walls. Load bearing walls can be replaced; but you need to transfer the load from the wall to a header and cripple to the foundation or suitable support.
Cleaning a Textured Ceiling or Wall
How to clean?? Very carefully! Use a cellulose sponge and generously apply cleaning solution. let cleaning solution set on the wall for several minutes to work on dirt, then dry and polish with a terry towel. Blot deep indentations carefully!
Painting Vs. Cleaning Walls
Buy yourself a good grade major paint, using a semigloss enamel or even a gloss in ultra-high abuse areas like exterior doors and door frames. For walls, use a lower luster eggshell or satin enamel for good effects.
Pick a good grade major paint and save yourself lots of premature repainting over the next 5 to 10 years. Cleaning enamel especially is fairly simple.
