An angle grinder is a very versatile power tool. It is not unfair to state that an angle grinder is an all-in-one tool that you can use for sanding, sharpening, polishing, cutting, and so much more.
Moreover, it is not even specific for a single surface, in fact, you can use it on various surfaces and for multiple purposes. If you ask me, I can go on and on about the uses and benefits of this superb grinder; however, we have to be a little more specific for our users for them to completely understand different aspects of this topic.
I frequently get this question from people and students about how to grind concrete with an angle grinder? So, today I am going to discuss the entire process by breaking it down into various steps for your better understanding.
If you want, you can break these steps down further, or merge them up as well. But make sure that you don’t break the sequence of the process otherwise, you will be responsible for the disastrous results. Anyway, I hope you enjoy this article and actually learn from it. So, let’s get started.
How To Grind Concrete With Angle Grinder
Step # 1: Get All Your Stuff In One Place
The first thing you need to do before you get started is to gather all the things you are going to need for this project. For starters, you must have an angle grinder with a blade of at least 4 to 5 inches in diameter, a dust shroud, diamond polishing pads, etc. Apart from that, you must also have safety tools such as gloves, face masks, eye goggles, knee pads, etc. And finally, you must keep a broom or a vacuum cleaner nearby so that you can clean up the place as soon as you are done working.
Step # 2: Clean Up The Surface
After you have gotten all the necessary tools where they need to be, your next immediate step must be to clean up the surface you are about to start grinding. Take all the furniture out of the room, and mop the floor thoroughly. You may consider washing out the place as well just to ensure a smooth performance of the grinder. However, be mindful to wait until the floor dries out completely before you start grinding otherwise, you may end up ruining both the concrete floor and your angle grinder.
Step # 3: Get Your Angle Grinder Ready
Now that your floor is all cleaned up and dry, it is time to divide it into different sections because in this way you will better be able to control your movements. This will also ensure that you don’t miss out on any part of the floor and grind consistently. Plus, it is also noteworthy to remember not to plug your grinder while you are positioning it. This little endeavor will save you from any mishaps while you are off guard and distracted.
Step # 4: Get Set Grind!
Once you have correctly positioned the angle grinder and divided the floor into sections, it is time to start grinding. Although you may disagree with my technique, in my opinion, it is best to start off with the corners of the room. Grinding the corners at first will help you grind the floor with more consistency. You can also use a smaller blade for the corners to get a neater finish. For the center, I suggest you stick to one center before moving on to the other for best results.
Step # 5: Deal With Any Imperfections
Once you are done grinding the entire floor, you need to vacuum away all the dust from the floor to be able to check out the results more clearly. If you find any inconsistency, grind it out with the angle grinder. However, make sure to clean up the grinder before getting started again because, in that way, the grinder will have more direct contact with the floor and thus help you do your work quickly and efficiently. Finally, wash or mop away all the dust residue on the floor. Also, have a look at what to do when Angle Grinder is overheating.
