Best Way to Power Trowel Concrete
Different types of concrete finishes may require a different types of trowels with different types of blades installed underneath them.
In this section, we will show you how to select the right trowel and what is the best way of troweling the concrete.
Choosing the troweling machine
If the area, you are finishing is less than 1000 sq. feet, you can the walk-behind trowel. For larger areas, you may prefer to go for a
. ride on concrete trowel
In the case of smaller areas to be finished, it is best to choose blades between 24 and 36 inches.
There could be two types of blades: float and finish blade. In some cases, you may get a hybrid blade, which has the skills of both floats and finishes blades.
When you have to trowel a larger area, we recommend you going got a 36- and 48-inches blade.
However, on corners, you may still have to use a 24-inch blade.
How to choose a proper concrete power trowel Floating the concrete Sorry, your browser doesn't support embedded videos.
While you are floating your concrete, you should use float blades. These blades will allow you to smooth out any bumps, hollow areas, and uneven zones.
It is recommended to run the trowel at three fourth of its speed, while you are floating the concrete and keep the blades flat.
Keeping the blades will also keep the machine from digging into the concrete and ruining all the progress you have made.
Once you have moved the trowel all over the concrete slab once with a flat blade, now it is time to turn the blades.
You must now turn the blades perpendicularly and then go across the entire slab again. This will help you to finish any spots that you have missed in the previous runs.
Finishing the concrete Sorry, your browser doesn't support embedded videos.
For finishing, you have to switch to the finish blades. Instead of keeping the blades flat as in the previous case, this time you have to turn them.
Blades should be turned to full pitch and the machine should be run at a full speed.
During finishing, you are finishing and sealing the pore of the concrete. Therefore, you will have to apply the highest pressures to the concrete slab in this case.
You may have to make several passes before you are sure that concrete is finished. You may continue finishing it until the desired look you want, that could be either a glossy one or a mate one.
Lastly, best practices in troweling concrete also involve the proper use of safety equipment. You should be wearing goggles, noise-free headphones, special gloves, and steel-toed boots.
