There is also a spray that you can buy. I have used the roller and the spray is much easier. You just hold it about 18" above the grout line (about arms length) and walk and spray. You don't have to bend over or get on your knees at all and since it dries clear, you can't see any overspray. It can be bought at Lowe's or Home Depot. Check in the tile department.
