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
It might be worth running a grinder along where the 2 substrates meet to give you a movement joint. Did the crack look like it followed the line of where the 2 materials meet? How long was the laytex down for before it cracked? was the floor primed before using the SLC?
The deepest places it has gone on at 15mm, the cracks seem to come from the centre and out in all directions. I didn't use a primer. Latex has been down a week but not sure when it cracked as I have been away all week and noticed today when I was about to continue tiling.
You think using a primer and putting it on in thinner layers would be better?
