A Guide On How To Cut Concrete

Cutting concrete is not as hard as most professional construction experts make it out to be, but it can prove to be a daunting task for most DIYers. It is possible to work on any concrete that requires a cut depth of around 4 inches. Cutting deeper than that only adds to the difficulty of the job at hand though, again, not impossible and should be left for the pros to handle.

The first rule is to understand the risks involved and thus take the necessary protective measures. The measures purely rely on knowing what to do when working on the concrete. You need to use the right tools and cutting technique to avoid making a mistake that can also threaten your very life. Below is a simple guide on how to cut concrete.

1. Lay Out The Area To Cut

Use a piece of chalk to draw lines, as desired, in the area of concrete you intend to cut. Dust and clean the surface before you draw the straight lines.

2. Choose The Cutting Blade And Saw

You can work using abrasive corundum masonry blades or diamond blades. The pros advocate for the use of the diamond blades since they are sturdier than the abrasive blades that a susceptible to breaking. You will have to replace the broken blades severally when doing a single project and the breakages also increase the chances of inflicting bodily harm on yourself.

As for the saw, you should go nothing less of a 15-amp circular saw, preferably an electric saw though a gasoline saw may also suffice. Make sure you pick a blade with the right diameter to ensure it slices through the concrete to the desired depth. Also, inquire about the best RPM to set the saw when cutting.

3. Start Cutting The Concrete

Run the saw at the correct RPM with the diamond blade set to cut into the concrete to a depth of 2 inches. The goal is to have an initial edge scoring the concrete that is straight, which makes it easier to do the final run that breaks the concrete to the desired depth.

Slowly low the saw while the blade runs place it on the line and slowing following it as drawn on the concrete. Avoid forcing the blade into the surface rather let it do the work; you only have to hold the saw firmly and guide the blade forward as it cuts.

Run the saw for intervals of around 1 �” 2 minutes, taking a break in-between to allow the saw to air cool for around 10 �” 15 seconds. It will help prevent the motor from overheating and for you to assess the condition of the blade.
