Where did that book come from? If it's a large area and you want to take a break, just let it set over night. Many tile setters just tape as they install the tiles. One reason to do it that way is to avoid creating speed bumps on the seams. I guess they have trouble making the tape job real thin. Did you use a wide flexible putty knife?
