How To Replace Old Plaster With Drywall During a Remodel

Renovating an older home can be an exciting yet challenging project, especially when it comes to updating the walls. Many older homes feature plaster walls that may have deteriorated over time, making them less than ideal for a modern living space. Replacing old plaster with drywall enhances the aesthetic appeal of a home and provides improved insulation and easier maintenance.

Let’s look at how to replace old plaster with drywall during a remodel to transform your home into a more comfortable and functional living space.

Preparing the Work Area

Before beginning the replacement process, prepare the work area thoroughly to ensure safety and efficiency. Start by removing any furniture, curtains, and decorations from the room to prevent them from accumulating dust or getting damaged. You should also cover floors with drop cloths and seal other areas with plastic sheeting to contain dust and debris. Wear protective gear, such as masks, gloves, and goggles, to safeguard against dust and potential hazards.

Next, use a utility knife to carefully score the edges of the plaster around windows, doors, and corners. This prevents damage to the surrounding areas during removal. Lastly, you should shut off electricity in the room for safety, especially if the walls contain electrical outlets or wiring.

Removing the Old Plaster

To begin removing the old plaster, use a hammer and chisel to carefully break away sections of plaster. Start at one section of the wall and work to uncover the wooden or metal lath structure beneath. Be gentle to avoid damaging the underlying lath or any electrical components hidden within the wall.

Handle each piece with care, as the process can be messy and produce a lot of dust. As you remove the plaster, collect the debris in heavy-duty trash bags to keep the workspace clean and organized. Once you completely remove the plaster, inspect the lath for any damage or needed repairs. This step is crucial as it ensures a smooth surface for the subsequent drywall installation.

Inspecting and Repairing the Wall Structure

Once you’ve removed the old plaster and fully exposed the underlying lath, inspect the wall structure for any signs of damage or decay. Look for issues such as rotting wood, loose lath, or compromised metal frameworks that could affect the stability of your new drywall. You should repair or replace any damaged components before proceeding. Secure any loose lath by nailing it back into place, and reinforce weak areas with additional supports if necessary.

You should also address any concerns with wiring or insulation and make updates or additions to improve the room’s functionality and energy efficiency. Properly preparing the wall structure is imperative for ensuring that the drywall installation process will be smooth and that the new walls will be durable and long-lasting.

Installing Furring Strips or Framing

Furring strips or framing provide a flat, stable surface for drywall installation, especially if the original wall structure is uneven or damaged. Begin by measuring the wall to determine the amount and length of furring strips or framing required. Install the strips vertically at regular intervals, typically 16 to 24 inches apart, fastening each securely to the wall’s underlying structure.

For added support, use a level to align the strips correctly and create a smooth, even surface. If you’re installing new framing, use 2x4 lumber and follow similar spacing guidelines. This additional layer supports the drywall and provides an opportunity to accommodate insulation or run electrical wiring in newly created cavities. Proper installation supports the drywall, resulting in a sturdy, professional finish.

Cutting and Hanging the Drywall

Once you have the wall prepped and ready, you can cut and hang the drywall. Start by measuring the dimensions of the wall to ensure precise cuts. Use a T-square and a utility knife to score and snap the drywall along the designated lines. Cut all the required panels before beginning installation to streamline the process.

Position the first panel at the top corner of the wall, ensuring it’s flush against the ceiling and fits against the adjoining walls. Secure it with drywall screws, placing them every 12 to 16 inches along the framing or furring strips. Continue hanging the remaining panels, cutting around doors, windows, and electrical outlets, and ensuring all seams are tight and staggered for added strength.

Taping and Mudding the Drywall Seams

Taping and mudding the drywall seams is critical to achieving a smooth, seamless finish. Begin by applying drywall tape over all the seams and pressing it into place to ensure it adheres well. Once you secure the tape, use a putty knife to spread a layer of joint compound, or “mud,” over the tape, feathering it out to blend it into the drywall. Allow this first coat to dry completely, which typically takes several hours. Once dry, lightly sand the surface to remove any imperfections.

Apply a second coat of joint compound and extend it beyond the first layer to achieve a gradual transition. After drying, sand again for smoothness. For a professional finish, you can apply a third coat, followed by a final sanding once dry.

Sanding and Finishing Touches

After applying the necessary layers of joint compound and ensuring they have dried thoroughly, you can tackle the sanding and finishing touches. Use fine-grit sandpaper to smooth out all treated areas, paying close attention to seams and nail or screw indentations. This step is crucial for achieving a perfectly smooth and professional look before painting or wallpapering. Once you finish sanding, thoroughly clean the area to remove dust particles, as they could interfere with the final finish.

Consider applying a primer to the drywall to prepare it for paint or decorative coverings. With careful attention to detail, your remodeled space will have a polished, seamless appearance that reflects the quality of your work.

Replacing old plaster walls with drywall during a remodel is a detailed process that requires careful planning and execution. However, the effort is well worth it, as the result is a modernized, aesthetically pleasing, and highly functional living space. By meticulously preparing the work area, safely removing the old materials, and ensuring a smooth and secure installation, you can enhance both the appearance and utility of your home.
