Grouting "outdoors" in shade and freeze concerns????
I'm in the process of finishing an exterior patio tile job for some friends and have a few questions in regards to grouting.
1) Some areas of the patio are always shaded; in addition, I'll be starting around 1pm when the sun is out (around 70 degrees) but finishing as the sun is going down (around 60 degrees).
Will any of this affect the drying process and thus possibly create discoloration issues? If so, what steps can I take to avoid that? I mean should I mist the sunny areas for a while?
2) Should I cover the patio or leave it exposed to the dew/elements over night? Note: There will be nobody available to cover the patio in case of rain until the following day.
3) Lastly, the instructions say to avoid any freezing weather for 21 days (after grouting) but I have no control over such. It does freeze at times in Florida, btw. What measures can I take to safeguard against such? I mean should I cover it with a freeze warning?
