Concrete floor repair

2. The trick to STRONG concrete is mix it as DRY as feasible and cure it as slowly as feasible. I'd use a paintbrush and wet the area with the latex, then JAM in concrete (something like 5 parts sand, one part portland mixed with just enough latex or water so that you can make a ball out of a handful when you squeeze it, ought to work fine). Then mist the area with water and cover it with plastic for a month or so. Check every week or so to make sure it isn't dried out, add more water. After a day it'll be strong enough to walk on and stuff, but try to keep it from drying out too fast (that's the point for wetting the area first, so when you put your concrete in the existing concrete won't wick away all your moisture before the concrete can cure).

Good luck

I've had good luck with it so far. I have used this for patching holes as it is waterproof, lining lower course of cinderblock to repel outside water, fixing cracks around drain and also as bonding element when redheads reinstalled in new holes.

Good Luck,
