We laid a tile floor in our kitchen last weekend and would like to grout it this weekend. how long after grouting do we have to wait before we can walk on it? We would like to install kitchen cabinets and would love to do it on Sunday if we grout on Friday night. I know you have to damp cure for three days but does that mean we can't walk on it for three days after grouting? Any other helpful grouting tips? Thanks in advance.
