Do You Have to Plaster Drywall?
Do you have to plaster drywall? The answer to this question depends on the scope of the project. If the drywall has visible imperfections or is in need of patching, plaster is your best option. Plaster covers a wide range of surfaces and is less susceptible to cracking. Because of its thickness, plaster covers more surfaces and has a wider range of application possibilities than drywall. It tends to do better covering screw holes and joints.
Drywall is available in large sheets that are screwed or nailed to the studs. To install it, a joint compound, often referred to as mud, is applied. This is less expensive than plaster, as the amount of joint compound required is much smaller. Dry drywall installation requires less plaster and joint compound than a plaster wall, and is less time-consuming. It also requires less joint compound than plaster.
If you’re planning to hang heavy items on the walls, you’ll need to use self-drilling or conical anchors. Then, you’ll need to attach the heavy items with toggle bolts or nails. Nails can easily penetrate the drywall, but if you try to hammer them into the plaster, they will bounce out. Unlike drywall, plaster walls don’t crack easily, but they are harder and will be prone to falling out.
If you decide to use plaster, you’ll want to hire a professional. Plaster requires more labor and specialized skill, so you’ll be paying more than drywall. Plastering your walls can cost anywhere from $2 to $10 per square foot. You may want to hire a professional to complete the job, especially if it’s a large job.
