My husband's cousin just redid our whole bathroom. The only thing he didn't do was seal the grout on the floors and walls. We have ceramic tiles on floor and walls.
He told us we could do it ourselves. Well, it is the only full bathroom in the house and we don't have any place else to take a shower so he said it was ok for us to shower without the grout being sealed.
Is this true? It is ok for the grout to be exposed to water and moisture? The sealer that we have is the kind you spray on. Is this adequate? He also said to caulk the joints with clear cauk after we seal. Is this correct?
Also, there is a small hole in the grout on the floor. Can this be patched by adding fresh grout? Did this hole occur from not sealing it first?
Thanks for any advice anyone can give! I hope we haven't done irreparable damage.
