When pouring a concrete surface, you want to make sure the finish is as flat and professional looking as possible. Large surfaces can be smoothed and finished very efficiently using a walk-behind electric power trowel, also known as an electric power float or helicopter float.

How long should you wait before using an electric power float or trowel?

Many factors, like air temperature, humidity and wind, can affect the time it will take for your concrete to dry. So, rather than using a hard-and-fast wait time, use this trick to check if your concrete is ready to be finished with your electric trowel: when stepping on the concrete, your footprint should be about a quarter of an inch deep or less inside the concrete, with very little bleed water in the footprint. This is the optimum time to begin finishing the concrete with your power float.

On the other hand, if your footprint in the wet concrete comes out to be deeper than a half inch, or if it has a fair amount of bleed water in it, it’s too early to use an electric power trowel. You’ll just have to wait for the concrete to dry a bit more before beginning the surface finishing process.

How to finish a concrete surface using an electric trowel

Usually, you will use a float pan and then a finishing blade on your electric trowel.

When the concrete is ready, the float pan is attached first, and you should push the power trowel in front of you slowly from one side of the concrete to the other, over the edge slightly, and then back in a new row.

After you have gone over the entire slab in this row-by-row pattern, make a second pass that is perpendicular to what you just did. This will compact the aggregate material in the concrete and make the surface nice and flat.

Next, attach the finishing blade to the electric power trowel and make two or more perpendicular passes just like with the float pan. Start with the finishing blade flat or with a very slight pitch. You can increase the pitch for the second pass.
