Do you push or pull a concrete saw?

Always let the saw do the work; simply guide its direction, but don't push it down into the concrete. You only need a quarter-inch cut at this point, but if the saw bites in a bit deeper, that's fine too. This first guided cut will ensure you keep your cuts straight during the rest of the project.

What's the best way to cut concrete?

Use a standard circular saw, equipped with a corundum or diamond blade, for small tasks. For slabs, it's best to cut through the top inch, then use a sledgehammer to break off the rest. The jagged edge left below the cutting line provides a good rough edge for the new concrete to bond to.

How deep should concrete saw cuts be?

Cutting Depth

When concrete saw cutting, aim to cut to a depth of one quarter to even one-third of the concrete slab thickness. When cutting concrete with a circular saw you don't want to cut too shallow or else risk random cracking.

How can I cut concrete without dust?

1. Wet cutting and water suppression. Wet cutting is essential as the name suggests, adding water into the mix to effectively reduce the amount of dust generated by up to 85% as opposed to cutting through dry concrete.

Can you cut concrete without water?

No water required: While wet cutting requires a constant stream of pressurized water, dry cutting uses airflow to prevent overheating. Use dry cutting when there is no water source or when the job site needs to stay dry at all times, such as indoor construction.

HOW TO USE A CONCRETE SAW | Basic Concrete Cutting Demonstration

What is a walk behind saw?

Walk-behind concrete saws have wheels that support the saw and allow the worker to push the saw in a straight line to cut inlay lines and trenches in roads, sidewalks, and other concrete surfaces. They are also used to create stress lines when pouring and setting concrete.

How fast do concrete saws cut?

Usually, a concrete saw can cut up to 10 feet per minute. The 14-inch blade can easily cut a 5-inch thick concrete.

How close to a wall can you get with a concrete saw?

How close can you slab saw parallel to a wall? The slab saw blade-guard needs approximately 2-3” clearance from the wall.

Should you wet concrete while cutting?

1. Wetting Concrete Reduces Dust Emissions. The main reason why we wet concrete before and during the cutting and sawing process is to reduce the dust emissions resulting from the cutting process. Typical dust is a health hazard owing to the effects it has on the respiratory system.

Why do concrete saws have water?

Most saws that require a water source will come with a way to supply it. Wet cutting jobs, while messy, offer more precise cuts. These saws operate at a high RPM, making them very efficient for large amounts of work.

Why do you use water when cutting concrete?

Keeping the blades cool with the constant spraying of water while it cuts through concrete will minimise the effect of wear and tear and will significantly improve or prolong the lifespan of the blade and the concrete saw in general.

Can I use my circular saw to cut concrete?

Contractors and homeowners use circular saws to cut large pieces of wood, metal, brick, plastic and even concrete. These saws provide a great deal of capacity and precision, but cutting concrete with a circular saw is not an easy job for beginners.

How long does concrete dust stay in the air?

Because of its small particle size, it can stay in the air for up to 12 days. Sometimes, when we don't see dust, we might still smell it e.g. if a room smells “like concrete” cement can be circulating in the air.

When should you cut concrete?

Timing for Cutting Concrete

The timing varies according to local conditions, but typically saw cuts can be done 4 to 12 hours after the concrete has been finished. In hot weather early-entry dry-cut joints are cut 1 to 4 hours after finishing; they're not cut as deeply as conventional cuts.

How do you cut grooves in concrete?
