Are you looking to update the look of your ceilings? You may be wondering if drywall can be installed over existing plaster ceilings. The answer is yes.

With drywall over plaster ceilings, you can give your home a fresh look while preserving the plaster's integrity.is a great way to enhance the look of your home while keeping the integrity of the plaster.

Dry walling over a plaster ceiling can be time-consuming, but with the right tools and supplies, it is an achievable task that anyone can do.

This blog post will discuss the steps involved in dry walling on top of a plaster ceiling, including the necessary materials and techniques for success. So read on for more information about how to cover plaster ceilings with drywall. Check out HandyWorkshop website to get more info about drywall.

Necessary Materials and Tools for Successfully Dry walling Over Plaster Ceilings

A drywall project on a plaster ceiling requires some basic materials and tools. To successfully complete the job, you'll need the following:

  • Drywall panels
  • Utility knife
  • Level
  • Safety goggles
  • Measuring tape
  • Nails or screws
  • Hammer/drill
  • Joint compound (aka “mud”)
  • Taping knife
  • Sandpaper or sanding block.

Step-by-Step Guide to Installing Drywall Over Plaster Ceilings

Once you've gathered all the materials and tools necessary for the job, it's time to begin dry walling over your plaster ceiling. This is a tricky and delicate task, so take the necessary steps to ensure that the job is done correctly and safely. So, here's a simple guide to help you get started:

Preparing the Area

When it comes to dry walling over plaster ceilings, the first step is preparing the area by removing any existing molding or trim pieces on the walls near the ceiling line, as well as any other obstructions (tables, chairs, etc.) that could get in the way during the installation process.

This is a critical step and should not be skipped, as it will help ensure a smooth and error-free installation process. It is best to wear protective gloves while doing this work, as some of the trim pieces may have sharp edges that can cause injury.

Additionally, it's essential to make sure that no electrical wiring or plumbing pipes are in the way before starting; otherwise, they may need to be moved or rerouted before beginning.

Locating and Marking All Joists

The next step is to locate and mark all joists with a stud finder. This is an important step as Drywall panels can only be affixed directly to joists for support and stability.

Additionally, marking them now will ensure that nothing gets missed later in the installation process when more accuracy is needed. Once the joists are located, use a pencil to mark them along their entire length, so they’re easy to spot during panel installation later on.

Installing Plastic Sheeting around Entire Work Area

Once all of the joists have been marked off, it’s time to install plastic sheeting around the entire work area including walls and ceiling to prevent dust from getting into other areas of the home.

This should be done using tax or staples along with a staple gun or hammer & nails whichever works better for your particular surface material. Doing this will also help protect walls and floors from any potential damage due to splatter caused by cutting or drilling sheetrock panels later on.

Additionally, don’t forget to cover vents with plastic sheeting otherwise; you might end up with a dusty mess after finishing up.

Cutting Sheetrock Panels to Size

Cutting Sheetrock Panels to Size

The fourth step involves cutting sheetrock panels down to size according to measurements taken in the previous step using a utility knife pre-drilling holes where necessary for easier cutting if needed (such as around doorways).

It’s important not only to take accurate measurements but also cut each panel straight so there aren’t any gaps between them once installed (you can use a level for extra accuracy).

Additionally, you should use safety goggles when cutting sheetrock panels since small pieces of drywall can fly off at high speeds during this process.

Attaching Sheetrock Panels to Joists

Once all of the sheets have been cut down to size accurately, it's time to attach them directly onto joists using either nails or screws depending on the surface material & weight requirements (as too much weight might cause sagging over time).

Make sure not only to affix each panel securely but also to leave enough space between each one so that the joint compound won't fill these spaces up later on during the taping job (roughly 1/8″ apart).

Also, remember that these nails will need countersinking, too tapping them slightly into drywall after securing so that they don't stick out too far, which could result in a bumpy finish once everything has dried up completely.

Apply Joint Compound Along Seams between Panels and Around the Room Perimeter

Now comes one of the most important steps: applying joint compound (also known as “mud”) along seams between panels & around the room's perimeter with a taping knife.

Start by evenly spreading mud across the entire seam & then smoothing out excess with back & forth strokes using a knife until desired thickness are achieved making sure there are no air pockets beneath drywall tape afterward since these will show through once the paint job is done.

Additionally, you want mud thick enough so that when drying up, shrinkage doesn't occur, resulting in visible cracks showing down the road.

Furthermore, you want to try to avoid adding too much compound given how difficult sanding is afterward if this occurs instead, opt to add multiple thin layers rather than one thick coat to achieve the same effect without additional messiness.

Use a Sandpaper or a Sanding Block Once First Layer Is Completely Dry

Finally, after letting the first layer of the joint compound dry up completely, use sandpaper or a sanding block to remove any bumps and lines left behind.

Make sure to do this section by section until satisfied with the results, then start applying the second layer covering the same area immediately without waiting too long otherwise, drying time is extended, further delaying project completion unnecessarily.

Furthermore, feel free lightly dampen the sandpaper block before each session and reduce the amount of dust created throughout the entire procedure, especially if working indoors.


Installing drywall over an existing plaster ceiling is not as difficult as it may seem. It takes time and patience, but with the correct knowledge and materials, any homeowner can successfully install drywall over their ceiling.

It’s important to use the correct tools and supplies to achieve a professional finished product.

If you follow our above steps for installing drywall atop a plaster ceiling, you will have an updated, beautiful room without having to tear out or replace any of your existing walls or ceilings. Good luck.
