If you are thinking about cutting through concrete, and you have not done so before, you need to make sure you understand the basics of cutting with a concrete saw before you get started.
1. Use the Right Diamond Blade
To start with, you want to make sure you are using the right blade. When it comes to cutting with concrete, you need to use a diamond blade. However, there is more than one type of diamond blade you can cut with.
There is a bond on the edge with a diamond blade that helps hold the diamond pieces in place. As you use the blade, the bond material wears away, and the diamonds are exposed. When it comes to cutting, you want the bond to wear away at a particular rate. If you get a blade with the incorrect bond material on it, the blade will wear away too fast.
If you are making a small cut, getting a multi-application diamond blade should allow you to get the job done. For example, if you are making a single cut through concrete, this blade can do just fine. If you are going to be doing a lot of cutting, you will want to get a specifically designed blade for the exact material you are cutting through.
2. Start with a Surface Cut
When you are cutting with a concrete saw, you will want to make an initial surface cut. With a surface cut, you are taking the blade and grazing the area where you will be cutting.
A surface cut will serve as a guide for you. It will show you where you need to cut and will give a nice edge to the start of your cut. It is easier to make a nice, straight cut when you are making a surface cut, and it will provide you with a guide as you cut deeper with the saw.
3. Use a Dust Control System
Next, you are going to want to use a dust control system. When you cut through concrete, the saw is going to be turning all that concrete. It is cutting through the dust. Even a small cut can produce a lot of dust. You don't want to breathe in that dust or let it get everywhere.
Ideally, you are going to want to have a vacuum specifically designed to collect concrete dust. This is a special vacuum that you can rent at a construction tool rental place.
As an alternative, you can use a water saw feed that can help subdue the dust. However, this can be messy to deal with and will create a slurry. The slurry is considered hazardous waste and must be appropriately disposed of.
4. Protect Yourself
Finally, you need to make sure you protect yourself. You will want to wear protective goggles to provide full protection so that dust doesn't get in your eyes. You are going to want to wear heavy duty face protection, such as a silica respirator. The particles from cutting concrete are small and harmful if they get inside your lungs, so make sure you have a respirator designed for the job you are doing.
You will also want to wear thick gloves, clothing that fully covers your body, and preferably steel-toed boots.
When it comes to cutting through concrete, you need to make sure you have the right blade, vacuum, and protective gear. Contact a concrete cutting service for more information.
