FAQs

What is the most suitable type of grinder for concrete floors?
Planetary grinders are typically lighter and easier to handle, making them ideal for simpler tasks such as smoothing out a garage floor. For more demanding, large-scale projects, rotary concrete grinders are recommended due to their robust nature and ability to handle tougher jobs.

How does a floor grinder differ from a floor sander?
While both tools are used for working on floors, their purposes are distinct. Sanders are primarily used for smoothing and finishing surfaces, particularly wood, to achieve a fine finish. Grinders, on the other hand, are more powerful tools designed to cut, grind, and polish harder materials like metal and stone.

What steps are involved in smoothing a concrete floor using an angle grinder?
To smooth a concrete floor with an angle grinder, start by grinding the surface thoroughly. After grinding, ensure to clean up all the dust and debris with a vacuum or a wet-dry vacuum to finish the process.

Are concrete grinders and polishers the same?
Concrete grinders and polishers are different tools designed for varied tasks. Grinders are used for more aggressive cutting and grinding, while polishers are suited for refining and smoothing surfaces. Choosing the right tool depends on the specific requirements of the job.

Can you provide insights on choosing a high-quality grinder for commercial use?
For commercial settings, especially for tasks like removing residues from tiles and carpets, it’s crucial to choose a grinder that balances power and usability. For instance, the Scanmaskin Scan Combiflex 650 Floor Grinder, though not a ride-on model, offers realistic performance with a coverage of about 900 sqft per hour and might be a suitable option within a budget of up to USD 30,000, particularly if you prefer an electric model over propane for indoor conditions.
