How to Repair Drywall Cracks
The interiors of most homes, offices, and businesses are covered with drywall. Also known as plasterboard, gypsum board, or sheet rock, drywall is a popular construction material because of its time- and labor-saving properties. Though drywall is fire-resistant, stable, and provides a reliable degree of sound and temperature insulation, it is less durable than plaster and sensitive to water and moisture. As you may know, drywall is only about 10 millimeters thick, making it susceptible to physical damage. All it takes is one hairline fracture for the crack to stretch out and give an unattractive appearance. Fortunately, drywall repair is easy. Beall Contracting offers drywall repairs, but we are also here to give some tips on how you can repair drywall cracks on your own.
Why Drywall Can Crack
Drywall is not as durable as plaster, so you should accept that it will damage more easily. However, physical pressure is not all that can crack drywall.
The seams where two sections of drywall converge are the most sensitive points where drywall is likely to fracture. There are many stressors that can cause these seams to crack. The settling of the building can lead to vertical cracks extending along the corners, windows, or door jambs of the rooms. Of course, faulty installations can also increase the risk of drywall cracking. Finally, fluctuations in temperature can cause the drywall to expand and contract, placing pressure on the seams.
It is a good idea to understand the source of the drywall stress so that you are not constantly repairing the same drywall. Get at the root of the issue to save time and money.
Hairline Fractures and Slight Cracks
If the crack or fracture is narrower than a quarter of an inch, then we have a quick guide on how to repair it. Before you begin, make sure you have the following tools and materials. These supplies can be found at your local hardware store:
- Mud Pan
- Utility Knife
- 6-Inch Putty Knife
- 12-Inch Taping Knife
- Paper Drywall Tape
- Pre-Mix Joint Compound
- Setting Compound
- Painters’ Tape
Now that you have your tools and materials ready, it is time to prepare your workspace. Move any furniture, fixtures, or belongings from the area. If the crack is near any woodwork or trim, then cover them with painters’ tape. Then, use a utility knife to cut a V-shaped notch the whole length of the crack.
Now, apply 1/8th inch of joint compound over the crack and apply a strip of drywall tape. Using the 6-inch putty knife, squeeze out excess compound and air from the strip of tape. Add a thin layer of joint compound over the strip to a few inches on each side of the strip. Let it dry.
Once the compound has dried, scrape off excess or rough spots with the putty knife. Use the 12-inch putty knife to apply another layer of joint compound over the tape with long strokes to smooth out the compound. Let it dry and scrape off or sand any dry particles.
For More Severe Damage
If the crack is wider than a quarter of an inch, then the entire drywall panel may need to be replaced. You can call Beall Contracting if you feel uncomfortable with such a large project. Our professional handymen are experienced and equipped to get the job done.
