I may use cement to fill some deep holes. I read that it cures in 30 days and will gas off for 30 days. This may however mean after a few hours it will mostly be cured and then it will gas off an unnoticeable amount but Im not sure.
I need to pick an appropriate product as I am sensitive to smells and vocs.
Regardless of whether it takes 30 days to fully dry/gas off, how long would you say before the smell from cement becomes unnoticeable?
