When it comes to renovating or repairing walls, one of the most daunting tasks is dealing with uneven surfaces, cracks, and imperfections. Traditionally, chasing walls involves using specialized tools and techniques to remove excess material, smooth out surfaces, and create a uniform finish. But what if you don’t have access to these tools or prefer to use something you already have in your arsenal? This raises the question: can you use an angle grinder to chase walls?
Understanding Chasing Walls and the Importance of Proper Tools
Before we dive into the world of angle grinders, it’s essential to understand the concept of chasing walls and why it’s crucial to use the right tools for the job. Chasing walls involves removing excess material, such as old plaster, mortar, or concrete, to create a smooth surface. This process is critical for various reasons:
- Improved aesthetics: A smooth wall surface enhances the overall appearance of a room, making it more visually appealing and increasing its value.
- Better paint adhesion: A smooth surface ensures a stronger bond between the paint and the wall, reducing the likelihood of peeling or flaking.
- Increased durability: A well-chased wall is less prone to damage from water, moisture, or physical stress.
Traditionally, chasing walls requires specialized tools, such as:
- Chasing chisels or hammer and chisel sets
- Pointing trowels and jointing trowels
- Scrapers and scraper blades
- Sanding blocks and sandpaper
These tools are designed to remove material efficiently while minimizing damage to the surrounding area. However, what if you don’t have access to these tools or prefer to use an angle grinder?

In summary, an angle grinder can be used to chase walls, but it’s vital to approach the task with caution, patience, and the right equipment. By understanding the pros and cons, techniques, and attachments, you can make an informed decision and achieve the best results for your project.
What is chasing walls, and why is it necessary?
Chasing walls is a process of creating a groove or channel in a wall to allow for the installation of pipes, wires, or other services. It is necessary to create a pathway for these services to run through the wall without being visible or causing damage to the surrounding structure. Chasing walls is typically done when renovating or building a new property, as it allows for the installation of essential services such as plumbing, electrical, and HVAC systems.
The process of chasing walls is often labor-intensive and requires specialized tools and equipment. Traditionally, chasers have used hand tools such as chisels and hammers, or specialized power tools like reciprorocating saws or routers. However, with the advancement of technology, angle grinders have become a popular choice for chasing walls due to their versatility, ease of use, and cost-effectiveness.
What are the benefits of using an angle grinder to chase walls?
Using an angle grinder to chase walls offers several benefits, including increased efficiency, reduced labor costs, and improved accuracy. Angle grinders are powerful tools that can quickly and easily remove material from the wall, making them ideal for large-scale projects. Additionally, angle grinders are highly versatile and can be used for a variety of tasks beyond chasing walls, such as cutting, grinding, and polishing.
Furthermore, angle grinders are relatively inexpensive compared to other specialized tools used for chasing walls, making them a cost-effective option for contractors and DIY enthusiasts. With the right attachments and accessories, angle grinders can be converted into a makeshift chase machine, allowing users to achieve professional-grade results without breaking the bank.
What type of angle grinder is best suited for chasing walls?
When it comes to chasing walls, it’s essential to choose an angle grinder that is powerful, reliable, and durable. A 9-inch or 230mm angle grinder is often the preferred choice, as it provides the necessary power and control to remove material from the wall efficiently. Look for an angle grinder with a high wattage motor, typically above 1200W, and a variable speed control to adjust the speed according to the material being cut.
Additionally, consider an angle grinder with a dustless system or a vacuum attachment to minimize dust and debris during the chasing process. This will not only reduce mess but also improve visibility, making it easier to achieve accurate results. It’s also crucial to choose an angle grinder with a comfortable grip and ergonomic design to reduce fatigue and improve control during extended use.
What type of attachments and accessories are needed for chasing walls with an angle grinder?
To chase walls with an angle grinder, you’ll need a few essential attachments and accessories. A chase blade or a diamond blade is a must-have, as it provides the necessary cutting action to remove material from the wall. A guide attachment or a track system can also be useful in helping to maintain a straight line and achieve accurate results.
Additionally, a dustless system or a vacuum attachment can be helpful in minimizing dust and debris during the chasing process. A respirator or dust mask is also essential to protect yourself from inhaling dust and debris. Finally, ensure you have a steady supply of blades and other consumables to maintain productivity and avoid downtime.
How do I prepare a wall for chasing with an angle grinder?
Before chasing a wall with an angle grinder, it’s essential to prepare the surface to ensure a smooth and accurate process. Start by cleaning the wall of any dirt, grease, or old adhesive to provide a clean surface for the angle grinder to cut through. Use a wire brush or a scraper to remove any loose material, and then vacuum the area to remove any dust or debris.
Next, mark the area where you want to create the channel or groove using a level and a pencil. Use a straightedge or a template to ensure accuracy and precision. If you’re working on a plaster or drywall surface, consider applying a layer of masking tape along the marked area to prevent the angle grinder from digging too deeply into the material.
What safety precautions should I take when chasing walls with an angle grinder?
Chasing walls with an angle grinder can be a hazardous process, and it’s essential to take necessary safety precautions to avoid accidents and injuries. Always wear personal protective equipment (PPE) such as safety glasses, a dust mask, ear protection, and gloves to protect yourself from flying debris and dust. Ensure the area is well-ventilated, and avoid working in enclosed spaces to prevent inhaling dust and fumes.
Additionally, maintain a firm grip on the angle grinder, and always keep your work area clean and clear of clutter to avoid tripping or slipping. Keep children and pets away from the work area, and ensure the angle grinder is properly maintained and serviced to avoid mechanical failure.
Can I use an angle grinder to chase walls on different materials, such as concrete or brick?
Yes, an angle grinder can be used to chase walls on different materials, including concrete, brick, and masonry. However, the process may require specialized attachments and accessories, such as diamond blades or core bits, designed specifically for cutting through hard materials. When working on concrete or brick, it’s essential to use the correct blade or bit to avoid damaging the material or the angle grinder.
Additionally, consider the structural integrity of the material before chasing a wall, as certain materials may require specialized techniques or equipment to avoid damage or collapse. Always consult local building codes and regulations, and seek professional advice if you’re unsure about the best approach for a particular material or project.
