Concrete Grinder FAQ
What is the best tool to grind concrete?
The best tool to grind concrete depends on the job size and the finish you need.
This can include:
Concrete floor grinder: Best for large-scale surface prep, consistent removal, and prolonged use
Handheld concrete grinder: Ideal for smaller areas, edges, and detail work with the right attachments
Concrete planer or scarifier: Suitable for aggressive removal and heavy-duty surface preparation
Tip:Always match the tool to the material you’re removing and the finish you want to achieve.
How much can a concrete floor grinder remove?
A concrete floor grinder can remove anywhere from a very fine layer up to several millimetres of concrete per pass. This depends on the machine, the grinding disc used, and the hardness of the concrete. For light finishes or paint removal, it might be as small as a fraction of a millimetre. For levelling uneven slabs or removing thick coatings, a more aggressive grind will reach those deeper layers. Always start with a lighter touch and adjust your technique as needed to get the removal rate and finish you’re after.
If you need to strip back concrete faster or tackle really tough surfaces, a concrete planer or floor scarifier may be the better choice. These use cutting drums to remove material more aggressively than a grinder, making them ideal for heavy-duty surface prep.
Do you need to use water with a concrete grinder?
Whether you need water with a concrete grinder depends on the type of grinding you're doing.
Wet grinders: Yes, you will need to use water. These models are designed for wet grinding, which helps reduce dust, keeps the grinding surface cool, and can produce a smoother finish.
Dry grinders: Some concrete grinders are designed for dry grinding, which is common for general surface preparation, often paired with a dust extraction system.
Always check the manufacturer's recommendations for your specific concrete grinder to ensure you're using it correctly and safely.
Can you use an angle grinder as a concrete grinder?
Yes, you can use an angle grinder for very small concrete grinding tasks, but it’s not designed for extensive use as a dedicated concrete grinder. You'll need to fit it with a diamond cup wheel, which is specifically for grinding concrete. Angle grinders are much less efficient for large areas, generate a lot of dust without proper shrouds and dust extraction, and can overheat if used continuously on heavy-duty concrete work. For any significant grinding job, a purpose-built concrete grinding machine should be your go-to gear.
