What type of concrete finishes will they be troweling on the concrete?
Most concrete finishes are a broom finish. The concrete is first troweled, than lightly broomed. Make sure they don’t pour the concrete and level it, then apply the broom. If may look ok in the beginning but it’s sure to crack and flake soon enough. Concrete has ¾” stone throughout its mix. These stone’s must be worked downward in the concrete with a magnesium trowel and then broomed. That’s minimum. I like to first level the concrete with a straight board. I then run my bull float across the concrete which acts as my magnesium trowel. After drying a touch, I’ll apply my steel trowel to seal in the top layer of concrete and then broom. Some concrete is finish after the steel trowel because it makes the concrete very smooth. This type of concrete is found indoors and will get slippery in rainy conditions.
