How to fill holes in concrete after demo job.
That's exactly what self leveling compound is designed to do,Tile.
In a nut shell--clean floor---prime with the recommended primer--mix with very cold water--
dump on floor---quickly push it around to help it level.--Add more for a deeper hole.
It is very important to read the instructions---and work fast.
I use one that is mixed with a liquid latex for the first coat--I've never had bond failure with this one.
However,I believe most brands work just as well.
