We had a back patio that had a roof over it and the concrete floor. We enclosed it now but it's not going to
be a heated room all the time. Just when we want to be out there. Enclosed because it would make a good wind block from the cold west winds here in Indiana.Now we would like to put something down over the concrete but have been told we can't do anything in the winter.Says glue can't be used because it won't stick to cold concrete. What is something we can use instead.
