In most cases, you are cutting through concrete has already set, whereas other jobs may require you to pour the concrete and make adjustments later. You will need to cut through the concrete using specialized tools, and there are specific safety precautions that you need to take. Here are some of the best concrete cutting practices that you can use to ensure that your customers are happy with the final result, all the while protecting yourself as you complete these concrete cutting jobs.
Should You Cut Concrete With Corundum More Diamond Blades?
There are certain tools that you will need to have in order to do this properly. If you are on a budget, and the job is actually very simple, you can use abrasive corundum masonry blades. These will cost under $10 each, and they are perfect for cutting through asphalt, stucco and also concrete. The reason that many people do not use these blades is that they are not very fast. For example, if you are cutting a half-inch pass through the concrete, it can take several minutes. They will typically only last for about 7 inches of a cut before they start to become dull. They also create plumes of dust, and the corundum on the blades will start to permeate a distinct odor, something that people that do masonry on a regular basis try to avoid. On top of this, they can start to glow very quickly because of the incredible amount of heat that is built up because they are not designed to be used for larger jobs. Most people use diamond blades, ones that are a diamond and metal composite, because they will last much longer and out cut corundum blades every time.
Dry Cutting Versus Wet Cutting With Diamond Blades
Dry cutting will work well as long as you have a toothed rim, or a serrated blade, one that can eject waste very easily. It also helps keep the blade much cooler, avoiding the common problem of overheating. On the other hand, you will not experience overheating at all when you are using wet cutting diamond blades. They will have a continuous perimeter that is very smooth, and the water can keep the dust down plus allow the blade to maintain a much lower temperature. You do need to use a special saw which is designed to apply the water and you must also use a GFCI protected extension cord. If you are doing larger jobs, this is the best solution for getting the job done fast with minimal dust. However, diamond blades should only be used with harder materials as softer materials will simply cause the blade to slow down or stop.
Do’s And Don’ts Of Concrete Cutting
There are a few things that you should do each time that you start one of these jobs, and a few things that you must avoid. You must never force the blade while you are cutting through. The weight of the saw is all you should need to make a proper cut. If you do have to resort to dry cutting, you should allow the blade to rest at least 30 seconds, allowing it to run free so it can cool down. Although you can use water with both a dry or wet blade, always use water with a wet blade for the best results. Finally, to protect yourself, always use gloves. You should also where safety equipment such as earplugs and a mask to protect your lungs. As long as you have the proper blade for each job that you are doing, and use these safety tips, you should be very efficient at completing each job you are hired to do.
In conclusion, these tips should help you complete each job as efficiently as possible. There are a few other strategies that you should implement. If you are going to be doing this regularly, using wet cutting diamond blades is the preferred method. The harder the material, the more likely it is you will have better success when cutting through more dense concrete or other materials. As long as you are purchasing diamond -tipped cutting blades, and you know the density of the concrete you are cutting through, you should have no problem cutting straight lines while maintaining the highest possible safety levels.
