I have mixed a batch of tile adhesive, unfortunately, I don't have time to use it all right now. However, I can resume tiling later today. It says on the package that the "open" time is 5 hours. I covered the adhesive in the bucket with water and put a plastic bag over it. Does it make any difference? Or should I just throw it away? It will probably be at least 6-7 hours from when I mixed it until I can use it again.
