I was wondering if anyone could give me any advice on how long to let concrete cure before introducing a hot tub. I have read that most concrete takes 28 days to reach the 4000 PSI strength, but does it need to wait this long?
Any advice would be welcome, trying to plan out the patio for the tub, too bad it won't fit on the 512 sqft screened porch easily, or not take up too much of the porch. The porch design does not lend itself to the installation of the spa, it is two 16x16 rooms offset by 8 feet between room.
