Some parts of my concrete floor were not very level so I have used some of the mapei latexplan trade, but in one area it has cracked so I have ripped it up. The substrate is an area where old meets new and the old cavity has been filled.
Any suggestions how to get over this so I can latex again?
Pics for clarity
Also this one keeps stealing the brush and jumping on me but I guess there is no solution to that lol
