What is Drywall?

Drywall is a panel of a compressed composite, gypsym (calcium sulfate dihydrate) that is reinforced with additional fibers for enhanced durability and resistance to humidity, water, mold, sound, and/or fire. Other names for drywall are: plasterboard wallboard, gypsum panel, gypsum and Sheetrock.

How to Choose the Right Type of Drywall?

There are several types of drywall, each of which has been modified to withstand and resist specific external factors, like: humidity, water, moisture, mold and fire.

Types of Drywall

  • Regular drywall – this drywall is white and available in many sizes from rather thin (1/4" or 6.5 mm) to thick (3/4" or 20 mm). Go to the drywall sizes and drywall thickness paragraph for more details.
  • Greenboard drywall – you can recognize it by its green paper covering. The covering was augmented with water-repellent molecules. This type of drywall costs more but does not soften when exposed to humid conditions. It is a natural choice for rooms where there is a high moisture level, for example a kitchen.

Aside from the different types of drywall, you can also find some drywall alternatives. Alternatives include tiles and cement board, commonly used in the bathroom.

Drywall Maintenance & Repair

 
1How to Install Drywall
  1. Place plastic sheeting at each door surrounding the room and turn off the air conditioner to prevent dust particles from traveling throughout the house and air ducts
  2. Measure the wall’s width and cut the sheet of drywall to be a ¼-inch shorter than your measurements
  3. Prop the drywall up and place it tightly against the ceiling
  4. Begin driving your drywall screws into the center of the drywall, placing the screws 16 inches apart and into the studs of your wall. Be sure to work from then center outward
  5. If you’re installing more than one piece of drywall, repeat steps 3 and 4*
  6. To install the final sheet of drywall, cut the drywall a ¼-inch shorter and begin driving your screws to place the panel
  7. After the final drywall panel has been placed, cut a v-groove into the short non-tapered ends of the panel
  8. After all the drywall panels have been installed, you must begin the joint work, which is taping the drywall joints
  9. *When installing drywall, it is important to plan for room fixtures, like windows, doors and outlets.

2How to Tape Drywall for Installation

After installing your drywall, it’s time to connect all the panels to create a solid wall by taping the seams of the panels with reinforcing tape and joint compound.

  1. Fill the beveled edge, or v-groove, with joint compound until it is about an inch thick with your trough, we recommend using a trough with a 6-inch blade.
  2. Apply paper drywall tape over the compound with your trough, about every 12-inches.
  3. Once the drywall tape has been applied, drag your trough along the tape.
    *Best practice is to begin working from the center outward, to avoid the tape from pulling and loosening
  4. Let the joint compound dry overnight
  5. After the compound is dry, apply a second coat of compound (a 10-inch trough is recommended) and let the second coat dry overnight.
  6. Thin the second layer of joint compound with water
  7. Apply the third (and thinnest layer) of compound to fill irregularities
  8. Let the third layer dry
  9. After the compound is completely dry, smooth the surface with a pole sander and 120-grit paper.
3How to Patch Drywall

The technique you use to patch drywall, depends on the size of the hole or scratch.

For small holes, you can use a ready-made drywall patch or repair kit. However, large holes may require you to create your own patch.

  1. Outline the damaged area using a carpenter’s square, at least an inch above and below the damaged area; also find and mark the nearest stud to the damaged area using a stud finder.
  2. Cut along your drawn outline, this may take several passes. Make sure that the edge of the patch goes over the stud to support the existing drywall and your patch.
  3. Remove the cut and damaged piece of drywall.
  4. Use a scrap piece of lumber (1“ x 3”) or plywood (3/4”) that is 2 to 4 inches longer than the height of your patch, as a support for your patch.
  5. Secure the support piece behind the opening for your patch using drywall screws.
  6. Cut a piece of drywall to fill the opening in the wall using your drywall knife and carpenter’s square.
  7. Install the patch by driving screws in to your installed support, at least an inch away from the edges of your patch, to prevent the drywall from splitting or crumbling.
  8. After the patch is secure, apply drywall tape, center tape over the seam created by the patch and existing drywall.
  9. Apply joint compound over the tape and let it dry overnight.
  10. Sand the compound to create a smooth flat surface, then apply a second coat of compound
  11. Sand the final layer and paint the area to match the existing wall.
