How to remove plaster from brick wall

It’s not uncommon for people to wonder why someone might want to know how to remove plaster from a brick wall. The reason is that brick walls have recently come back in interior design. While walls made of brick were not very popular in the past, they are now considered fashionable.

Knowing whether you plan to leave the brick wall exposed or replaster is essential because it will determine the best approach and tools. Suppose you intend to replaster the wall with modern materials. In that case, the most efficient way to remove the old plaster is by using an SDS hammer drill with a broad chisel head. This tool will allow you to break through the plaster quickly and without causing damage to the bricks behind.

On the other hand, if you prefer to keep the brick surface exposed as a design element, you will need to remove the old plaster without harming the bricks. You can still use an SDS hammer drill with a chisel head to do this, but you will need to work more gently and carefully. This approach will enable you to remove the plaster while preserving the bricks.

Regardless of your chosen approach, the same tools can be used for both projects. If you require assistance with any of these tasks, I can provide you with a list of the necessary tools and instructions on how to use them.

Tools and safety gear you need for removing plaster from the brick wall

If you plan to work on a brick wall project, you will need some tools to help you get the job done effectively and safely. Here is a detailed list of the tools that you will require for the project:

1. SDS hammer drill with chisel head: This tool is essential for chiseling the plaster away from the surface.

2. Use a regular hammer to break plaster gently: You can use this hammer to remove any plaster on the bricks. Be sure to do this gently so as not to damage the bricks.

3. Angle grinder with cup wire brush head to gently remove plaster: This tool helps remove any plaster stuck to the bricks. Be careful while using the grinder, as it can damage the bricks if not used properly.

4. Construction-level vacuum cleaner for dust control: A lot of dust is generated when working with bricks and mortar. Use a construction-level vacuum cleaner to clean the work area and minimize dust.

5. Regular wire brush for tricky corners: A regular wire brush can be used to clean the tricky corners of the wall that are hard to reach with other tools.

6. Plastic and cellular or hardboard for floor protection: Use plastic and cellular or hardboard to protect the floor from debris or dust generated during the project.

7. Shovel: You can use a shovel to remove any debris from the work area.

8. Bucket and possibly a wheelbarrow: You will need a bucket to mix the mortar and possibly a wheelbarrow to transport the bricks and other materials.

9. Screwdrivers for electrical parts: If any electrical parts are on the wall, you will need a screwdriver to remove them.

10. Hydrochloric acid meant for plaster removal: Hydrochloric acid can remove any stubborn plaster stuck to the bricks.

11. Compression sprayer for acid: A compression sprayer can apply hydrochloric acid to the wall.

12. Washing tools to wash hydrochloric acid off: You will need some washing tools to remove the hydrochloric acid once the plaster is removed.

13. Protective sealer for bricks: After cleaning the wall, you can apply a protective sealer to the bricks to prevent damage.

14. Two-sided step ladder: You must work near the ceiling, so you need a firm place to stand on. Regular ladders are dangerous and kill many workers every year.

Make sure you have the following protective gear while working on the project:

1. Eye protection: Protect your eyes from debris or dust that may fly off while working.

2. Ear protection: Brick wall work can be loud, so protect your ears with earplugs or earmuffs.

3. Safety helmet with chin trap on: Wear a safety helmet to protect your head from debris or falling.

4. Gloves (working and rubber for acid wash): Wear gloves to protect your hands from sharp edges or chemicals.

5. Working shoes that prevent ankle twisting: Wear shoes with good ankle support to prevent injury.

6. Working clothes that can be disposed of if you splash acid and such: Wear clothes that you don’t mind getting dirty or even disposing of them if they come into contact with any chemicals or debris.

Feel free to ask if you have any questions or concerns about the tools or protective gear required for the project.

How to remove plaster from brick wall
By removing the old surface, it’s possible to use it as an interior design element.

Removing plaster from the brick wall for new plastering

To ensure the job is completed successfully, it’s essential to start by spreading protective coverings over the floor and furniture where the work will occur. This will prevent any damage to anything other than the specific piece of wall being worked on.

Before starting the work, it’s essential to check that all necessary personal safety measures are in place. This includes wearing appropriate safety gear such as gloves, eye protection, and a dust mask.

Removing the wall involves using an SDS hammer drill. This powerful tool can quickly and efficiently remove large sections of the wall. To make the job easier, starting at the top of the wall is recommended so that gravity can do most of the work. Once a nice chunk has been removed, it’s easier to chisel away downwards, using the most expansive drill head possible to leave a smoother finish for replastering.

When chiseling away the wall, it’s also a good idea to fill up buckets and a wheelbarrow with plaster debris to avoid having to do it all at the end. This will also keep the area clean and safe to work on.

After removing the wall, it’s essential to clean it up thoroughly. This includes vacuuming any dust and debris on the ground and sweeping the area to ensure it’s spotless. It’s also recommended to check the area for any remaining debris or dust that may have settled on furniture or other surfaces.

Once the wall has been removed and the area has been cleaned, it’s time to start preparing for the project’s next phase. This may involve replastering the wall or making other repairs as needed.

Removing plaster from brick walls to get a fashionable brick wall

This job may be more challenging. When working on old houses, the texture of the bricks may differ, and parts of the mortar may come off, or it may not be on the wall at all. However, we have a goal and know how to achieve it.

To begin with, we need to ensure that everything is protected with plastic and board coverings. We should use a wide chisel with an SDS hammer drill, but we need to be gentle not to damage the bricks. Depending on how hard the plaster is attached to the wall, removing it may take some time. However, it is usually relatively easy.

Removing the trash little by little is a good idea to keep the working area clean and comfortable. Once the entire wall is done and no plaster is left, we can use an angle grinder with a wire cup brush to remove most of the remaining plaster.

Next, we need to apply hydrochloric acid, followed by washing. We use compression sprayers that can handle mild acids when working on outdoor rendering. These sprayers have a pistol that you can use to spray the acid after pumping pressure into it. However, it is best to ensure that the area is well-ventilated.

After spraying the hydrochloric acid, we should leave it to work for the time recommended by the manufacturer’s label. Then, we can gently brush it with a wire brush. Depending on its effectiveness, we may need to repeat this process several times. Before the final step, we should fix any areas where mortar is missing or broken off.

We should leave the surface looking as even as possible. Old and new mortar can be challenging, but we should aim for a lively surface. It’s essential to wash off the acid thoroughly and neutralize it with the appropriate cleaning equipment.

What are the modern materials used for replastering a wall?

Plaster is a versatile building material used to create smooth surfaces on walls and ceilings. Several types of plaster are available for construction purposes, such as cement plaster, gypsum plaster, mud plaster, lime plaster, waterproof plaster, and stucco plaster.

Cement plaster is made by mixing cement and sand in a 1:3 ratio, and it is commonly used as a base coat for walls before the final coat of paint or wallpaper is applied. Gypsum plaster, on the other hand, is made by mixing gypsum powder and water to create a paste that can be applied to walls and ceilings. It is known for its smooth finish and is often used in areas where a high level of finish is required.

Mud plaster, as the name suggests, is made by mixing mud and straw and is commonly used in rural areas where other types of plaster may be limited. On the other hand, lime plaster is made by mixing lime, sand, and water. It is known for its durability and ability to prevent dampness.

Waterproof plaster is specifically designed to resist water. It is commonly used in bathrooms, kitchens, and other areas where moisture is present. Finally, stucco plaster is made by mixing cement, sand, and water. It is commonly used to create decorative finishes on walls and ceilings.

Each type of plaster has its own unique set of properties and is suited for different applications in construction.


Unearthing aged surfaces can be a daunting task that requires a considerable amount of time and patience. However, the result can be stunning and worth the effort.

Ensuring your safety is paramount, beginning with wearing the proper safety gear. You never know what chemicals were used to create older plaster, so protecting yourself from inhaling its potentially harmful particles is essential.

In addition to wearing the appropriate gear, it’s crucial to clean every surface thoroughly. The use of acid in the process can be hazardous to both your skin and respiratory system, making it imperative to wear skin-tight safety goggles, long rubber gloves, and clothing that can be discarded.

By taking all the necessary precautions and utilizing the correct equipment, you can safely and successfully excavate old surfaces and discover the hidden beauty.
