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.

You can use a thin set cement or if the cavities are not that big I have used PL 900 clue level it with a putty scraper it dries like marble and very strong.

Good Luck

Hi Blake,

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!
