Introduction
Welcome! If you’re reading this, you likely need to learn how to remove plaster from a room or even your whole house. I started with odd jobs and now specialize in concrete work, often tackling plaster removal from lath or brick walls.
This guide will simplify the plaster removal process and help prevent damage. Homes that are at least seventy years old likely have lath and plaster walls, a method used until the 1950s, which involves applying plaster over thin wooden strips.
Owners of older homes often value plaster walls for their thickness and insulation, which contribute to effective soundproofing. Additionally, plaster provides a timeless aesthetic that enhances the charm of older homes, unlike drywall, which may not be as visually appealing. However, plaster can deteriorate over time, so it’s important to address any damage you notice.
Understanding plaster removal and the materials used will help you tackle this task with confidence, leading to improved results.
Here are some tips for preparing a room before you begin the plaster removal process. You can find helpful information on how to fill screw holes in plaster walls in this guide. This advice is also useful if you’re removing plaster from walls.
Basics of Plaster Removal Techniques
Before starting plaster removal, it’s important to understand what plaster is and why it may need to be removed. Made from sand, water, and either lime or gypsum, plaster has been used for its durability and aesthetic appeal on walls for centuries. However, it can crack, chip, or detach from the wall, which makes removal necessary.
In many older homes, plaster serves both decorative and structural purposes. Identifying signs that indicate plaster needs removal rather than just patching is crucial. Look for specific indicators that can help you make this decision.
- Deep cracks
- Crumbling edges
- Areas where plaster has pulled away from the lath
If you notice a crack wider than 1/8 inch or can poke your finger through a loose section, it may be time to consider removal.
Removing plaster instead of simply covering it can lead to a more stable and visually appealing finish, depending on the condition of your walls and your renovation goals. If you want a smooth surface or plan to install new wall systems, removing old plaster may save you time in the long run. Always assess the plaster’s condition carefully, and consult a professional for guidance if you’re uncertain.
Tools and Materials for Plaster Removal
To simplify plaster removal, break it down into manageable steps. Understanding how to remove plaster involves completing essential tasks to prepare.
Collect the essential tools and materials needed for effective plaster removal. Make sure you have everything on hand before starting the project.
- Hammer
- Chisel
- Putty knife
- Drop cloth
- Crowbar
- Utility knife
- Dust mask and safety goggles
- Plastic sheeting
- Trash bags or disposal bin
Once the plaster is removed, consider repurposing it for creative projects, like making plaster flowers.
- Clear the room completely.
- Remove all millwork.
- Cover vents, cold air exchanges, and the thermostat.

- Set up a disposal chute (optional).
Clear the Room
Plaster removal can create a lot of mess, so clear the room of all items, including furniture and decorations. Remove everything that can be moved, and cover larger pieces with a drop cloth to protect them from dust and debris.
Keeping fragile items out of the way will help prevent damage. A clear space will also make it easier to move around, which can reduce frustration during the project.
Remove Millwork and Fixtures
In older homes, trim around windows, doors, and baseboards is often secured with long nails. Start by removing the trim to make the job easier and label pieces for reinstallation. Use a utility knife to cut through any paint or caulk sealing the trim to the wall.
Make a small gap between the trim and the wall to locate the nails, then use a crowbar to pry them off carefully to avoid breakage. If the trim is difficult to remove, lightly tapping the crowbar with a hammer can help loosen it.
Cover Vents and Thermostat
To prevent plaster dust from clogging your HVAC system, turn off your furnace. Protect the thermostat with plastic and tape over all vents to contain dust that could spread throughout your home. For added protection, consider using a damp cloth to cover the vents temporarily.
Seal Openings
To minimize plaster dust spread, seal all openings by closing doors and placing a rolled towel at the base. For archways between rooms, use a clear plastic drop cloth as a barrier to help contain dust within the work area.
Turn Off Electricity
Cutting electric wires while the power is on can be dangerous. Check for switches and outlets on the walls, and if uncertain, use a scanner to locate the wires. Remember to label the circuit breaker you’ve turned off for easy identification when restoring power.
Check for Water Pipes
In older homes, water pipes may be hidden. If you suspect their presence, consider using detectors, as damaging a pipe can lead to costly repairs. Once located, mark the pipes’ positions on the wall to avoid accidental damage during plaster removal.
Protect the Flooring
If you plan to keep carpeting, cover the floors with a thick canvas tarp. For hardwood or tile, use thick cardboard or an old piece of carpet for protection. A combination of plastic underneath and a board on top can facilitate easy cleanup, and ensure the protective covering is secured to prevent shifting during work.
Prepare for Debris Disposal
If there’s a window in the room, open it, remove the screen, and set up a chute for easy disposal. For interior rooms without windows, identify the quickest path to the outdoors and keep it clear. Using a large trash bin or bags can help simplify the disposal process.
Be sure to protect the flooring along your path, as you may need to clean up after carrying plaster outside. Having a helper can make this process easier, as they can hold the door open or manage the trash bags.
In old houses, the millwork (or trim) around windows, doors, and baseboards is often secured with very long nails. Before you can remove the plaster, all this trim needs to come down, including the information on strengthening your plaster ceiling and the steps for removing plaster.
Preparing the Room for Plaster Removal
The earlier steps lay a strong groundwork for plaster removal, but additional techniques can further enhance the process.
Understanding the Necessary Tools
Having the right tools is essential for successful plaster removal. Below is a list of the tools you’ll need for the job.

Allocate sufficient time to complete the project, especially if you’re working alone. Dedicating a weekend or a few days can help you maintain focus and finish the job without feeling rushed.
Cleaning Up After Plaster Removal
Once you’ve removed the plaster, cleaning up is the next important step. Be prepared for the cleanup process by following these steps:
- Vacuum thoroughly to remove fine dust.
- Dispose of plaster debris properly, following local rules.
- Check the underlying lath or wall surface for damage that needs repair before applying new finishes.
- Wipe down surfaces to remove any remaining dust.
Exploring Alternative Wall Finishes
If the plaster is in decent condition but doesn’t match your style, consider alternatives to full removal. Options like skim coating or applying a new layer of plaster can refresh your walls while keeping the original material. This approach can save time and help retain some of your home’s character.
When to Hire a Professional
If the task feels overwhelming, consider hiring a professional. Plaster removal can be complicated, and a contractor has the experience and tools to manage unexpected issues like hidden pipes or electrical wiring, ensuring the job is done safely.
With proper preparation and these helpful tips, your plaster removal project can be a fulfilling experience that refreshes your home’s appearance.
Types of Plaster and Their Characteristics
Before starting the plaster removal process, it’s important to know the types of plaster in your home. Understanding these types will help you choose the right removal techniques. Understanding these types, such as those used in creating realistic faux stone, will help you choose the right tools and methods for removal.
Traditional Lime Plaster: Characteristics and Uses
Traditional lime plaster is made from lime, sand, and water. Its breathability and flexibility make it well-suited for older homes, as it absorbs moisture and promotes a healthier indoor environment. When removing lime plaster, use a hammer and chisel or a plaster knife, taking care to avoid damaging the underlying lath.
Gypsum Plaster: Properties and Applications
Gypsum plaster dries quickly and is less prone to cracking than lime plaster, but its strong adhesion can make removal tricky. To remove gypsum plaster, begin by scoring the surface. Then, use a demolition hammer to break it apart, which can minimize damage to the wall structure underneath.
Stucco: Features and Common Uses
Stucco is often found on building exteriors and consists of cement, sand, and lime, providing a durable and weather-resistant finish. Removing stucco can be labor-intensive, especially if it’s applied thickly. Essential tools for this task include a chisel, hammer, and pry bar, and be prepared for significant debris and dust during removal.
Acoustic Plaster: Benefits and Considerations
Acoustic plaster is designed to reduce noise levels and is often found in older buildings. It contains materials that absorb sound, making it effective for soundproofing. However, removing acoustic plaster can be challenging due to its texture and the potential presence of hazardous materials like asbestos. If you suspect your acoustic plaster may contain asbestos, consult a professional before attempting removal.
Health and Safety Considerations
Removing old plaster can present health risks, so it’s important to take precautions. Follow these health and safety tips to ensure a safer removal process:
Wear Appropriate Protective Gear
Always wear a dust mask, safety goggles, and gloves when removing plaster. This gear protects you from dust and debris that can irritate your lungs and skin. Make sure your dust mask is rated for fine particles to provide effective protection.
Check for Asbestos Before Starting
If your home was built before the 1980s, the plaster may contain asbestos, which is hazardous when disturbed. Test the plaster for asbestos before removal. If asbestos is present, hire a licensed contractor who has the equipment and training to handle it safely.
Ensure Proper Ventilation During Work
Keep your workspace well-ventilated while removing plaster. Open windows and use fans to promote air circulation, which helps reduce dust and harmful particles. Working in a well-ventilated area limits your exposure to dust.
Stay Hydrated While Working
Removing plaster can be physically demanding, so remember to stay hydrated and take breaks to prevent fatigue. Having water nearby and working in a well-ventilated area will enhance your comfort during the task.
Be Mindful of Your Surroundings
Before starting, remove furniture from the area and protect the floors with drop cloths. Organize your tools and keep them within reach to minimize accidents. A tidy workspace promotes safety and efficiency.
Plan for Dust Control
To minimize dust during removal, use a vacuum equipped with a HEPA filter. This helps maintain a clean workspace and simplifies cleanup afterward. Additionally, using damp cloths to wipe down surfaces after the job can capture any lingering dust.
