I had an outdoor porcelain patio laid in Dec 22. Due to the rain and snow it was not grouted. We have done some research and it looks like the joints needs to dry out and we need rising temp above 6 degrees Celsius for the grouting with Norcross grout. However our patio guy said this week is ideal to have this done, expert advice welcome please, Also how long for drying after and at what temp please
