If the plaster on your walls has seen better days or just doesn’t fit your taste, you may easily cover it up with drywall.
The only tricky component of the process is installing the drywall sheets directly on top of the existing plaster.
Because of fading and normal wear and tear, plaster walls can lose their appeal over time. In addition, it can cost a lot to fix plastered walls. If plasterboard is used instead, the job can be done for much less.
They’ll be more attractive, more powerful, and more profitable as a direct result of your efforts.
Plaster ceilings, a common architectural feature of older homes, are particularly endearing. That’s why it was the go-to ceiling material before drywall was developed in the 1950s.
However, restoring old ceilings can protect the building’s historical integrity and aesthetic appeal, which is why drywall is often the go-to repair material.
When new drywall can be installed directly over the old plaster, there is no need to remove the plaster and create an even bigger mess. Save both time and money with drywall.
Plaster that is too old or damaged to mend or is too much of a hassle to remove can be covered with drywall at a low cost. Drywalling can be installed right on top of plaster, which is why. However, a lot of groundwork is needed for this to be successful.
Remove any loose plaster and replace it with plaster screws into the wood lath strips behind it.
A solid surface is necessary for drywall installation. Plaster screws are installed in a manner analogous to that of a washer, so preventing the plaster from splitting.
Any loose plaster should be scraped off the lath and the resulting hole in the wall should be patched.
After the old plaster has been stabilised, the walls are usually in good enough condition to be refinished with drywall.
Drywall is easier to deal with and may be put up and fixed for less money than plaster. Drywall panels can be installed directly over plaster walls, but doing so requires careful planning and preparation.
Drywall Installed Over Plaster Is The Best Method For Creating Walls That Look Fantastic
Cracked plaster is more common in older homes because of the increased likelihood that they have settled and shifted over time. When this happens, the surface may develop unattractive fissures.
Plaster repairs can be time-consuming and expensive, therefore drywall installation directly over existing plaster is an alternative.

In the event that you have access to cracked plaster, you can attempt to repair it.
Homeowners without specialised training can patch the holes, but if you want the wall to seem as good as new, you need hire a professional with experience in floating plaster.
If you can’t get such an expert, even a novice homeowner should be able to patch up the damage.
As the number of plasterers declines, the cost of hiring one rises, which is one reason why many individuals choose to instal drywall over damaged plaster walls instead.
Installing new drywall could be the greatest option if you’re looking for a simple and low-cost way to revamp the aesthetic of your home. Have them redone if you want to keep the character of an older property intact and can afford the hourly fee; do them yourself if you just want a clean look.
Make Sure Your Plaster Is Locked Down Tightly
In order to correctly adhere the drywall, any loose plaster must be fastened to the wood lath strips. Why? Because doing so requires a solid foundation. To fully secure the plaster, you must use plaster screws.
There is no need to worry about the plaster splitting because of these screws because of the specific fittings.
Scratch off any loose, flaking plaster that’s clinging to the lath with a putty knife. Once that’s done, you can use a piece of drywall to cover the gap.

Putting up drywall and spackling it
It’s time to strip the moulding
If you’ve made sure you have everything you need, you can begin. Starting with the window and door casings, remove the baseboards and any crown moulding before proceeding.
The flat side of the pry bar is what you need to accomplish this.
In addition, employ the flat-head screwdriver to remove the covers from all of the switches and outlets.
It’s worth repeating that you need to take your time so that nothing breaks or cracks while you’re doing this.
Collect The Initial Section Of Drywall You Will Require
A new sheet of drywall should be placed flat against the wall and on top of the one-inch-thick spacer board.
Drywall screws measuring 2 inches in length can now be used to fasten the drywall to the stud. It will take a drill to secure the screws.
Using a six-inch interval along each stud, continue screwing in your anchors. You should put a quarter-inch of gap between each screw and the panel’s edge.
Locate The Floor Studs. Against the plaster wall’s back
Studs Finder can help you locate the wall studs that are concealed by drywall.
Use your pencil to make a note of the stud’s precise location once you’ve located it.
Nonetheless, when making the mark, you should get as low to the ground as possible.
Apply this method to each stud in the wall. If the studs are visible near the floor after you remove the baseboards, you won’t need a pencil to indicate their placement; you can just use them as guides while installing new flooring.
Applying drywall requires extra care
A joist needs to be screwed into on the shorter end.
From the corner, measure out 8 feet to establish the drywall’s final edge. When a sheet of drywall does not end on a joist, measure from the corner to the centre of the farthest joist it will cover.
Add a mark to the wall to show the dimensions.
Start by placing a T-square along the line as a guide for scoring the drywall’s face using a utility knife. Using the pliers, pry the scrap drywall away from the grid.
Use a pair of scissors to sever the back side of the paper and dispose of the resulting shreds.
Get the Panels Ready. Cut all of the drywall to the right size by measuring it carefully.
A measuring tape and electric saw will be required for this project’s completion.
Plasterboard sheets need to be accurately measured and cut for proper installation. Therefore, you won’t waste time, energy, or resources.
The next step is to prepare the space for the electrical boxes and lighting by cutting holes in the drywall. Handsaws, jigsaws, and speciality saws are just some of the options available for this job.
The main purpose of this cutting is to make the sheets small enough to fit around the edges of the doors, windows, and corners. Using a chalk line as a guide is recommended for cutting lengthy distances.
A drywall rasp can be used to smooth the snipped edges of the pieces.
Once the panels are in position and you’re ready to secure them, you can cut any edges that are too close together with a sharp knife.
Don’t forget to trim these areas before you screw the drywall into place. Make sure the drywall fits snugly against the wall before pressing it into place.
Hang your drywall over the plaster
Use a caulking gun to splatter a lot of Liquid Nails onto the wall. Drywall sheets should be installed horizontally, starting at the top of the wall and working your way down. When installing drywall over plaster, this method has proven to be the most effective.
Start at the top of the wall and work your way down until the first sheet of drywall is flush in the top upper corner.
You’ll have a much easier time of things, and the task itself will be easier, if a friend or family member can help you out with it.
Drywall screws two inches in length should be used to fasten the drywall to the studs once it has been positioned properly. You should leave at least an 18-inch space between screws and countersink each one.
Next, a piece of drywall is fastened to the wall’s footing after being cut to size.
Check to see whether there is a gap between the upper and lower drywall sheets after you have finished placing the 2 inch long drywall screws. Usually, there will be some room between the two sheets.
Determine the size of the gap with the tape measure, and then cut a sheet of drywall to fit into the opening. Verify that the upper and lower sheets, as well as this component, have straight, flush edges.
To Insert Screws
Drill 2-inch drywall screws into the wall studs behind the plaster using a Phillips-head screwdriver bit.
You can use the notations on the spacer boards to help you find the appropriate spots for your studs.
Place screws every 6 inches along every stud, but no closer than 3/4 inch to the drywall’s edge.
Fill in all the cracks, rough edges, and stains with mud and tape
After the drywall has been hung, the following step is to tape and mud the seams.
The next step is to use a quality compound to fill in the cracks and seams, tape over the exposed edges and seams, and repair any other imperfections.
Taping the flat seams between wall panels is typically advised to be done with fibreglass mesh tape, as this is what is recommended by most professionals in the field.
The tape should be applied, and then the compound of your choosing should be used to fill in the spaces between the taped areas. Each fresh layer must be applied very carefully, with a gentle sanding in between.
It’s time to get creative with your wall design when the compound has dried. It’s your room; feel free to get creative with the decor.
Considerations for Draping Over Present Structures
Whenever you have made the decision to re-hang something, there are only a few fundamental considerations you need make before you get started.
Fittings for Electricity
A quarter of an inch of depth will be removed from all of your electrical outlets and light switch boxes.
Even though you installed them such that they would be flush with the wall, you have really increased the thickness of the wall by about a quarter of an inch.
As before, they were mounted such that their surfaces were even with the surrounding drywall.
There is absolutely no reason to panic. Extensions for these boxes can be purchased at your local home improvement store and installed quickly and easily.
Structures Such As Door and Window Jambs
It is recommended that you expand the jambs of any doors or windows that will be rehung on the same wall, as they will be too short without doing so.
The same rule applies to electrical junction boxes.
Extenders can be found in the moulding aisle of any hardware or home improvement store.
You can then adjust their size to your specifications after you bring them indoors.
Staining the jamb extensions to seem like the original jambs will be the most challenging portion of this project, especially if the woodwork has already been stained.
If you want to discover replacement wood that is an exact match for your existing furniture, you may cut off a little piece and bring it with you when you shop.
Both Molding and Edging
One other thing to keep in mind before you get started is that you’ll have to take down and recut your baseboards, chair rails, and crown mouldings.
However, if you remove them gently and with care, there’s no reason you can’t use them again.
Keep in mind that every time you rehang a wall, the room’s circumference will decrease by a quarter of an inch, so the trim pieces will need to be chopped down to meet the new measurements before you can reattach them.
Studs
Installing new drywall over existing drywall is functionally equivalent to installing drywall in a new structure.
The most noticeable difference is that the studs cannot be seen to guide anchor placement. In any case, if you don’t mind spending a little extra cash, you may fix this problem by buying a stud finder and marking the spots on the walls where the stud finder shows there are studs.
After the drywall is up, we’ll get to this.
In the event that you are unable to acquire a reliable stud finder or are unwilling to pay the money, another option is to just mark the ceiling in advance to show where the vertical studs are. Once again, this is an option for dealing with the issue.
It makes sense to make any necessary markings on the wall now, as it will be covered up soon anyhow.
Working with panelled walls makes this much simpler because the original nail holes can be seen. Take the holes to the top and put a mark there.
Finding a stud, measuring it off in both directions, and then testing to determine where the next one is are all good ways to verify the standard assumption that there are 16 inches between the studs if panelling is absent.
This will spare you a lot of trouble after you’ve started hanging your new artwork.
Putting Up Drywall Over Plaster Walls And Ceilings
Remove any loose plaster that may have been hiding ceiling damage
Use a utility knife to cut through things neatly for a professional look. Plaster can be secured to lath above it with screws and plastic washers to prevent it from peeling off.
Laths are the wood slats that run perpendicular to the ceiling joists.
It is vital to use screws that are long enough to penetrate both the plaster and the lath, as the thickness of the plaster can vary.
Locate the ceiling joists or studs that are covered up by the drywall
In newer construction, wall studs are placed 16 or 24 inches on centre, however this might vary.
If you can see the joists of the ceiling above in the attic, your work will be simple; otherwise, you’ll need to use a stud finder or make some exploratory holes. When you find the joists or studs, snap chalk lines to mark the centerpoints of where the drywall will be screwed.
Be Extra Cautious With Drywall Installation
A joist needs to be screwed into on the shorter end. From the corner, measure out 8 feet to establish the drywall’s final edge. If the sheet of drywall will not end on a joist, then the measurement must be taken from the corner to the centre of the farthest joist it will cover.
Add a mark to the wall to show the dimensions. Start by placing a T-square along the line as a guide for scoring the drywall’s face using a utility knife. Using the pliers, pry the scrap drywall away from the grid. Make a slit in the back of the paper and toss the resulting scrap.
Raise the drywall over the damaged area of ceiling
You’ll require another person’s help with this. Also, a “deadman” is needed. Deadman is short for “dead man’s support,” and is a T-shaped support tool made from 2x4s.
It is used to hold up the drywall from the ground up when it is being hung.
It’s also possible to hire drywall lift equipment from a hardware or home improvement store. Five screws, two in the drywall and two in the joist nearest the panel’s centre, should do the trick.
Do the same thing at both ends, but this time make sure the screws are exactly one inch in from both sides.
The screwheads should be flush with or just below the paper’s surface; they shouldn’t poke through. Complete the drywall installation along the row. Put in the new rows in the same way you put in the old ones.
The end joints must be shifted four feet to the side to prevent the joints of the first row from aligning with the joints of the second row.
Plaster that is loose or sagging must be reattached using screws and plaster washers before dry wall can be installed
Glue applied to the drywall’s reverse side is one way to lessen the need for these fasteners.
Another is to check that the screws are actually holding on to the framing and not simply the lath.
Putting up a flexible channel may be useful if there is a room above the plaster ceiling.
These grooves even out the surface and lessen the sound waves that can travel through it.
Secure the channels at right angles to the joists. Then, attach the drywall panels perpendicular to the grooves using screws.
Simple Tips for Drywalling over Plaster
Elegance
Professional drywall installation results in a smooth, attractive, and aesthetically pleasing surface. It is far more challenging for amateurs to compete with experts, especially in the areas of taping and mudding.
Drywall can be painted as many times as you wish, taking on virtually any hue or surface texture you can imagine.
Put Down The Fires
Dry wall has the ability to reduce the rate at which fire spreads through a building. Plasterboard has an average fire rating of thirty minutes, indicating it can contain a fire for that long provided it is installed correctly.
Type X drywall is available, and it has a fire rating of an hour and a slightly different core from standard drywall.
It is common practise to compare plaster’s fire resistance to that of drywall, but there is no obvious winner.
Plastering using wood lath, as was once common practise, was dangerous and should be avoided. Plastering over wire mesh is a modern method of construction.
Properties of Insulation
Although mudding and taping are more time-consuming steps, they are crucial in producing a high-quality end result.
Drywalling over the old plaster will give you a more refined, modern, neat, and aesthetically acceptable look, but only if you’re in the mood for a change.
Affordability
In order to avoid the high cost of repairing or replacing plaster walls, many people choose to cover them with drywall instead. The affordable price makes it a desirable addition to many houses.
In most cases, drywall is installed at a lower cost and in less time than plaster.
Nothing will be difficult to instal or repair
Putting up drywall, or restoring damage to it, is a simple process. Although mudding and taping are more time-consuming steps, they are crucial in producing a high-quality end result.
However, drywall built over existing plaster will result in a look that is more sophisticated, modern, clean, and aesthetically pleasing if you’re bored of the same old thing.
Conclusion
Drywall saves time and money. A drywall can be installed directly over plaster.
After plaster stabilisation, walls can often be refinished with drywall.
Plasterboard can be put over plaster, but it isn’t easy. However, plaster walls can be covered in drywall with sufficient planning.
Ceiling restoration preserves a building’s charm.
Older homes often repair plaster with drywall. Preparing for drywall installation prevents fractures and breaks. 2-inch drywall screws hold the drywall to the stud. Before installing drywall, measure 8 feet to find the outermost joists.
Cut drywall to size before installing. Installing drywall requires accurate cutting and sizing.
Ask a trusted friend or family member for help if you’re uncomfortable with this step. Rehanging walls takes planning. Taping flat wall panel seams requires fibreglass mesh tape.
After the compound dries, design your wall’s look.
Baseboards, chair rails, and crown moulding must be removed and recut. The most noticeable difference is the absence of the studs, which previously indicated anchor placement.
If you can afford it, a stud finder may work. Screws must penetrate plaster and lath to secure drywall.
“Deadmen” raise sheets from the floor when hanging drywall. The drywall slows fire spread. Painting drywall multiple times yields practically any colour or finish.
Amateurs are at a disadvantage in taping and mudding. Plaster’s fire resistance is comparable to drywall’s. When you’re ready for a change, drywalling over the old plaster will make the room look more modern, clean, and elegant.

Frequently Asked Questions About Plaster
Is Drywall Installation In The Bathroom Permitted Over Plaster?
It is possible to instal drywall over plaster in a bathroom; however, you will need to use a green board resistant to mould. Plaster, on the other hand, does not have pores and does not support mould growth, in contrast to drywall, which does. Therefore, utilise a drywall product designed specifically for use in bathrooms for added defence against it.
Drywall Of 14 Or 38 Of An Inch Over Plaster?
When installing drywall over previously constructed walls, you must use the narrower 14-inch variety of the material. If you use thick drywall, the electrical boxes and light switches will have to be installed too far back in the wall. Therefore, you are going to have to have them repositioned.
If you decide to use thicker drywall, you should prepare for the possibility that the electrical boxes will need to be moved forward and that you will need to use longer screws to access the studs.
Is It Necessary To First Remove The Old Plaster?
Plaster, being brittle and rigid, is susceptible to cracking due to the normal settling in a house. Therefore, before attaching new drywall panels, removing any old plaster may not be required in all cases; however, doing so may be recommended in certain circumstances.
Is Drywall Capable Of Being Screwed Over Plaster?
When a room has older plaster walls that are damaged somehow, one option for sprucing it up is to instal drywall on top of the plaster already there. The walls are given a smooth, clean surface ready for new paint, paper, or trim after an overlay of drywall is applied.
How Can I Locate A Joist When The Ceiling Is Covered In Plaster?
If you want the light to appear nearly horizontally across the ceiling, you should hold a flashlight right up against it at a very gentle angle to the surface. Also, keep an eye out for bumps in the paint. They almost always point to the presence of a nail behind the plaster, and wherever you find a nail, you’ll find a joist nearby.
