Tips & Advice
Are drywalls installed with nails or screws?
Either nails or screws are effective in hanging drywall. Nails are cheaper, but it takes longer to hammer nails them into a wall stud. Screws are a bit more expensive, but are can be drilled in faster and are generally more secure, which is ideal for ceiling installations. Screws can be easier to remove if you need to take out a piece of drywall. The difference is going to be negligible.
How is drywall installed?
Installing drywall is really not a complicated process.
- Decide on nails and hammer or screws and a drill.
- Once you have your drywall, start by putting adhesive on the wall studs (the vertical structure that holds the wall in place). This helps hold it in place while nailing or drilling it in.
- Align the sheet across the ceiling and across the studs and hammer/drill a few nails/screws into it, approximately 12-18 inches apart. Make sure the nail heads sit BELOW the surface. You will cover this will filler later.
- Measure and cut your next piece of drywall. Be sure to use a rasp (file) to hone any rough edges.
- Hang, nail/screw into place and continue the process. Be sure to mark location of wall studs so you know where to hammer/drill.
- Once you have measured and hung all drywall, you will use filler to cover any gaps and the nails or screws to create a flat surface.
- If you have electrical boxes in the wall, be very careful working around them.
How much weight can drywall support?
How much weight drywall can support varies on several factors. First is thickness. Drywall comes in three standard sizes; 5/8, 3/8, and 1/4. Obviously, thicker is sturdier. Drywall is surprisingly sturdy and can support up to roughly 40 pounds on a single anchor stud, but the key to strength is to spread the weight out over multiple anchors, the objects you drill into the wall to hang things on that come in a variety of sizes and strengths. Using more of them distributes the weight out and lessens the burden on the individual one. So, heavier objects, like mirrors, will need more anchors. Different types of anchors include: toggle bolt, threaded toggle, molly bolt, threaded anchor, and the various types of picture hangers. Hanging objects from a wall stud (the wood borders that make up your wall and sit behind your drywall) will provide maximum strength.
There is no healthy dust; it’s all harmful to a degree. Breathing drywall dust frequently, over time, will likely cause symptoms similar to allergies. Frequent inhalation can lead to sinus and throat irritation, coughing, phlegm, and reactions similar to asthma. This condition can be easily remedied by proper ventilation and wearing a face mask when working around drywall. If you are hanging drywall on a one-time basis you are probably OK, but prolonged exposure will eventually have harmful effects. Use a mask; they’re cheap and readily available.
Is drywall fire resistant?
Yes, there are fire resistant drywalls available. Different manufacturers use slightly different ingredients and some use fire-resistant additives. For instance, fire-rated gypsum uses glass-fiber reinforcement, along with other additives that enhance its ability to resist fire. Type X drywall is rated fire resistant and contains the glass fiber reinforcements as well. Type X has special core additives for enhanced fire resistance, and is usually 5/8 inch thick. This does not mean they are fire-proof, it means they can stand up to fire better and can last longer than lesser-built materials. Ultimately, everything can burn.
What is the difference between drywall and Sheetrock?
Generally speaking, Sheetrock and drywall are the same material, but the difference is that Sheetrock is a trademarked name, drywall is not. All Sheetrock is drywall, but not all drywall is Sheetrock. There are ingredients in Sheetrock that are unique to it, thus the reason they were able to patent it. Other than that, the make-up is generally the same. Different brands of drywall will have varying ingredients, but the appearance and texture is usually very similar. So, while there are some minor ingredient differences, the major difference is just the name.
How much does drywall cost?
To figure out your costs you need to factor in the drywall cost with the installation cost. You can get small drywall sheets for as little as $10, with prices escalating based on bigger size. You can reasonably expect to pay between $1.50 and $3.00 per square foot to install drywall in your house. Other factors in installation costs include size of the materials, transportation, and equipment costs, site prep and cleanup. With so many variables, it’s strongly advised to get estimates from contractors in your area to get a real time idea of cost. However, if you are handy and are considering this as a DIY project, hanging drywall is totally doable if you have the right tools, patience, and know how. Head to places like Home Depot or your local hardware store to start getting real estimates on your cost.
Chances are, if you live in a modern home, the inside walls are made of drywall. Drywall boards or sheets are made from wood pulp, plaster, or other assorted materials. For basic gypsum drywall, the calcined gypsum is mixed with water and other additives and pressed together to form the board. The face side is smooth, while the back is rougher. Drywall is one of the easiest installations, making it ideal for building or remodeling. It is also noise reducing and has fire-resistant properties due to the water and other additives in the base. It is popular, abundant, and a very cost effective and efficient alternative to plaster and other wall building materials.
