How to use a concrete cutter for different materials
Whether you are referring to it as a floor saw, flat saw or walk-behind asphalt saw, this machine is very important for projects involving concrete and asphalt. Knowing how to cut concrete slabs or how to cut a concrete slab efficiently can save time and effort. These saws are versatile, handling everything from decorative concrete to fixing driveways or leveling asphalt on roads.
However, the cutting process may vary depending on the type of concrete you are working with. In this guide, SIMA experts will provide tips for saw cutting concrete slabs, focusing on green concrete, cured concrete and asphalt overlaid concrete.
Essential tips for saw cutting concrete
Before learning how to saw cut concrete, always prioritize safety. Here are some key precautions:
- Wear proper protective gear: earplugs, eye protection, a respirator mask (especially for dry cutting), and snug-fitting clothing.
- Choose the right diamond blade for the material you are cutting, and inspect it for any warping or damage before mounting.
- Use wet cutting when possible. It helps prolong blade life, improves accuracy and reduces harmful silica dust.
- Never apply extra pressure to speed up the cutting process, and avoid forcing the machine to cut faster.
- Always turn off and lock the saw after use to ensure safety.
By following these steps, you will not only know how to cut concrete effectively but also keep your tools in optimal condition.
Cutting green concrete with a walk-behind flat saw
Green concrete, which is freshly poured, should be cut within 24 hours to prevent cracking. When learning how to cut concrete slabs of green concrete, aim to cut between 1/4 and 1/3 of the slab’s thickness. A blade between 12” to 14” is recommended for this task.
How to cut cured concrete
Cured concrete requires careful selection of the diamond blade, depending on the aggregate in the mix. If you are planning deep cuts, opt for a blade with at least a 20” diameter. However, making multiple shallow cuts can help preserve the blade and ensure smoother results.
Cutting asphalt overlaid concrete
Asphalt overlaid concrete presents a unique challenge, as it requires different blades for each layer. How to saw cut concrete in this situation? For asphalt, a single pass with an 18” blade is usually sufficient, depending on the thickness. For the concrete underneath, multiple shallow passes (2-3” deep) are necessary to avoid damaging the blade.
How to cut concrete safely and efficiently
Mastering how to use a concrete cutter like a walk-behind saw ensures better results, whether you’re cutting green, cured or asphalt overlaid concrete. Remember to choose the correct blade, use wet cutting methods where possible and always follow safety protocols. By understanding the proper techniques for how to cut a concrete slab or how to saw cut concrete, you can complete projects efficiently and extend the life of your equipment.
