How long to wait after patching concrete shower slab?
I've opened up the slab under a shower to replace the trap. I planned to put gravel around the pipes and then put concrete to repair the slab. But I read somewhere you need to wait 7 days for the concrete to cure, keeping it wet all the time. I had not planned on this.
Oh'Mike mentioned using sackcrete. Does this material cure faster?
Also, the entire slab under the shower is slightly out of level. Should I try to fix this at the same time I fill the hole around the trap?
