Why is my concrete rough?
The most common reason people get a rough surface is due to laitance . This happens when the concrete is troweled too early with the steel trowel. The trowel closes off the pores of the concrete so when this is done while there is still too much moisture in the concrete, the moisture gets trapped inside so it’s not able to evaporate properly. When the concrete cures, it usually looks very smooth and attractive however once you start sanding, that soft, dusty “cream layer” easily sands away and you’re left with a gritty, rough surface. If this cream layer isn’t removed and the concrete is sealed, you will notice that the sealer will chip or peel very easily. It can happen after a few weeks or even several months after being sealed however, it will eventually come up and need to be fixed. If you see this happening when you begin to sand, sand off the entire cream layer until you reveal the rough, gritty surface underneath. Then you can begin repairing.
