Is there downtime after the turf is installed?

Is there downtime after the turf is installed? Will I have to wait to step on it or have my pets play on it? Do I have to let it sit outside to let it sink in?

There is no downtime after your artificial grass gets installed. You can literally walk and play on it immediately! Think about carpet installation, people can even walk on it during the installation (only if you are not in the installer’s way), same for the artificial turf, no downtime whatsoever, simply enjoy it!
