I recently had to repair a very small area (roughly a 2 ft wide x 1 ft rectangle) of my basement concrete floor after a water pipe repair. This area will have carpet installed over the concrete. The rest of the floor is completely dry and in good condition.

What is a minimum wait time I should wait before beginning pad and carpet installation?

    ('dry' in) 24h? If you're going to use glue, then anywhere from a month to 3m (to cure and completely set). And that's after using w/e the bottle of glue says to do to concrete that only been cured for X amount of time. - Also, you're not supposed to let it 'dry' before it sets. For the first three days (week?) you are wetting it, then covering it back up with plastic sheet, so that it can cure more before it dries out.

  • First one's got the "28" days but paint instead of glue, and the second talks about using plastic. Everything is a dupe @FreeMan ... This one's my fav, but only mildly related : How long will Concrete bond together when poured over multiple days?

You suppose to keep it moist for a week to prevent stress induced cracks.

After that another week or more to let it dry.

The dry time will depend on the temperature.
