In addition, consider the health of the machine before grinding. It will be best to check the machine’s abrasive disc, motor health, and diamond polishing pad before using it for efficient performance.
Step 3: Start Grinding
Grinding is the main delicate part of the operation. While the grinding process is straightforward, you may encounter a few challenges reaching out to corners.
The grind has to be effective with adequate precision. If you want to grind corners successfully, consider using a smaller device and start with the edges.
After grinding the concrete edges, work your way inwards and swing the machine with consistency.
You can decide to swing your angle grinder in different directions, but moving in a circular form is the best way for enhanced performance. It is advisable to run the tool in a way you consider ideal.
After grinding a portion of concrete with your angle grinder, you’ll have a chunk of dust around the perimeter zone.
While the dust shroud plastic is an integral part of the machine, it also prevents the wheel from grinding areas close to the wall, causing a pile of dust.
Solve this problem by removing the dust shroud from the machine and focusing on areas of concern.
Step 4: Fix Imperfections
After grinding the required surface, it’s time to check the results and work on the defects. A careful and thorough evaluation will reveal the loopholes and areas that need smoothening.
Although it requires extra effort and attentiveness, grind the areas of concern again if you want an even floor.
Remember that removing the dust shroud plastic will allow you to grind areas close to the wall. When you have an even floor, it’s time to remove excesses and debris with a vacuum cleaner or mop.
The quality of this exceptional machine when it comes to grinding grind concrete will leave you with a lasting impression.
How to Smooth Concrete with an Angle Grinder
Experience has a part to play when it comes to smoothening concrete with angle grinders. But if you want to know how to smooth the concrete with an angle grinder, follow the below steps:
