I have a cement shower pan that has some high and low spots that I want to fix. It all slopes towards the drain, but it will suck for tiling.
To fix this I need to chisel some cement away and add a thin layer in some spots. Its a fairly large shower and I definetly do not want to remove the whole thing.
So my question is, will I comprimise the strength and stability of the pan by doing this?
I am using kerdi with kerdi drain.
That shower of yours is putting up a hell of a fight. You can grind down the high spots and then use the thin set with your trowel to fill in the low spots. Use a shop vac to catch the dust coming off the grinder. That should keep the dust down as much as possible. It's still a pretty messy job.
Good luck with it!
