You're a regular DIYer. Instead of paying a contractor, you've decided to tackle your concrete job on your own. You've learned what type of concrete is best for your needs and even how to install it. Now comes the task of cutting your concrete. When it comes to concrete joint cutting, the type of blade you use and when you cut are two important factors. Make sure you know what to expect.

Cutting Time

When cutting concrete control joints, timing is important because it can have a significant effect on the end result as well as how easy the task is. Popular thought is to cut the concrete immediately after installation or several days later, once it's had time to settle and cure. In terms of cutting the concrete right away, this can be beneficial because it can help reduce the risk of cracking during the process, which can sometimes be higher when the concrete has had a chance to settle.

However, cutting the concrete before it's had a chance to cure can sometimes be more challenging because it's often more abrasive. Before concrete cures, the mortar and sand in the mixture haven't had a chance to fully bond yet. While neither option is necessarily better than the other, knowing what to expect can help you choose which is best for you.

Cutting Blades

It's one thing to understand that diamond blades are best for concrete cutting. However, it's also important to understand that there is no one-size-fits-all solution. Diamond blades come in varying bond degrees. The greater the bond level, the thicker the blade. Which type of blade you choose should depend on the abrasiveness of the concrete and the type of sand used in the mixture.

In terms of abrasiveness, concrete that has not fully bonded or cured will need to be cut with a hard-bonded diamond blade. However, concrete that has been mixed with a sharper sand, such as river bank sand, will need to be cut with an even thicker blade. Once you know when you're going to cut and the makeup of the concrete, it's best to take this information to a professional so that they can assist you with choosing a blade.  

Whether you're renting your concrete cutting equipment or purchasing, don't overlook the assistance of a professional (such as one from Web Granite Supplies). In addition to giving you helpful tips on the cutting process, a professional can also assist you with choosing the option.
