10 Methods How to Demo Plaster Walls
1. Use a Utility Knife to Score the Plaster:
A utility knife is a great tool for scoring plaster. Begin by slowly working the knife along the surface of the wall, taking care not to press it too hard. This will allow you to create a clean line and make sure the wall is evenly scored. However, be careful not to press too hard and damage the plaster!
2. Use a Putty Knife or Scraper to Remove Any Loose Plaster:
Before you can begin to patch the damaged area, you need to remove any loose plaster. Use a putty knife or scraper to carefully and gently scrape off any loose plaster from the walls. Be careful not to scrape too deep, as this can cause more damage. Once you have removed all of the loose plaster, clean up any dust to ensure that the area is free of debris.
3. Wet the Area with a Sponge or Spray Bottle:
Once you have removed the dirt and debris, wet the area with a sponge or spray bottle. This will help to loosen any remaining dirt before you begin cleaning. Make sure to remove any excess water with a towel before moving on to the next step. Though it may seem counterintuitive, wetting the area can actually help to make your cleaning more effective. Make sure to avoid soaking the area, as this can damage your floor or furniture.
4. Apply a Bonding Agent to the Area, if Needed:
If you are installing tile over a difficult surface such as concrete, wood, or vinyl flooring, it may be necessary to apply a bonding agent to ensure the tile adheres properly. Bonding agents come in a variety of forms, such as liquids, mastics, and mortars. When applying the bonding agent, you will want to make sure that the entire surface is covered and that no air pockets are present.
You should also use a trowel to smooth out any bumps or uneven areas. Once you have applied the bonding agent, it should be allowed to dry according to the manufacturer’s instructions before proceeding with the installation.
5. Apply Joint Compound to the Area with a Putty Knife or Trowel:
Once you have cut away the damaged drywall, it is time to apply joint compound also known as “mud,” to the area. A joint compound is a paste-like material that can be used for filling cracks, and gaps and repairing damaged surfaces. To apply it, use a putty knife or trowel to spread the joint compound evenly over the damaged area.
Then, scrape away any excess with a knife before allowing the compound time to dry. Make sure you fill in all crevices, cracks, and gaps in the drywall as much as possible. Once it has dried, you can then sand down and smooth out the surface with a piece of coarse sandpaper.
6. Feather the Edges of the Joint Compound:
Once the joint compound has been applied, use a drywall knife to feather the edges of the joint compound. This means that you should lightly press down on the edges of the joint compound with your drywall knife. This will blend the joint compound smoothly into the wall and make it look more professional.
If you are having difficulty feathering the edges, try using a wet sponge to do this. This will help you get more even results. Finally, use a damp cloth to wipe away any excess joint compound that may have been left behind. Now your wall should be smooth and ready for painting or staining.
7. Allow the Joint Compound to Dry Completely:
Once you have applied the joint compound and smoothed it out, you will need to let it dry completely before you can sand and paint. This can take anywhere from an hour or two, to overnight, depending on how thick the joint compound is that you’ve used. Make sure to check the package instructions for drying time estimates.
Once the joint compound has completely dried, you can use a sanding block or sponge to lightly sand the area until it is smooth and free of any bumps or imperfections. After that, you’re ready to prime and paint over the patch.
8. Sand the Area Smoothly with Fine-Grit Sandpaper:
When the wood filler is dry, use fine-grit sandpaper to make the area smooth. Start with 80-grit sandpaper and then progress to 150-grit or finer if desired. Sand in long, even strokes with the grain of the wood until it becomes smooth. Once you’ve achieved your desired level of smoothness, wipe the area with a damp cloth to remove any dust or debris.
However, be careful not to over-sand the area, as this can cause scratches that may be difficult to remove. If your filled area is large or deep, you may need to use a palm sander or power sanding tool to get it completely smooth and even. Once the area is fully sanded, use a soft cloth to apply some wood wax or furniture polish to the area. This will provide added protection and help bring out the natural beauty of the wood.
9. Prime and Paint the Area as Desired:
After the area has been prepared, patched, and smoothed, it is time to prime and paint the area. Priming the wall will help to ensure that the paint will adhere to it better. Choose a primer designed for the type of surface you are working with, such as drywall or wood. Use either a brush or roller to apply the primer in even strokes across the wall.
Allow the primer to dry completely before proceeding with painting. Once dry, use either a brush or roller to apply the paint in even strokes across the wall, allowing each coat of paint to dry before applying another. Once finished, allow the paint to cure for at least 24 hours before using the room again. With these simple steps, you can give any space a fresh new look!

Things to Consider When Demo Plaster Walls
1. Ensure that the Wall Is in Good Condition:
Before you begin any demolition work, make sure that the plaster walls are in good condition and free from cracks or other damage. If there are any issues with the walls, it is important to address them before starting any work.
2. Remove All Furniture and DéCor:
Remove All Furniture and Décor from the room before starting to demo plaster walls. Removing these items will ensure that they are not damaged during demolition.
3. Cover Floors:
Covering floors with thick plastic sheeting or tarps is important to safeguard them from any dust or debris created by removing walls and ceilings made of plaster.
4. Wear Protective Gear:
Wearing protective gear such as gloves, dust masks, and safety glasses is important to protect yourself from any flying debris or dust created by demolition works.
5. Start From the Top:
When demoing plaster walls, it is best to start from the top and work downward. This ensures that any dust will settle on the ground rather than falling onto the area you have already worked on.
6. Use Appropriate Tools:
Using the right tools for demolition work is essential to ensure a safe and efficient job. Tools such as hammers, chisels, and crowbars are commonly used for removing plaster walls, but remember to use caution when using them.
