Flowers not Grout Bond

A helpful man at the tool store informed me I could use any ammonia based cleaner for the old scratched grout to prep it for the new grout. Moreover that a bonding agent wasn't so necessary. I'll run with that since its a rental. Plus the awesome agent I sought turns out to be pretty pricey.

Since I was already at the store I got some flower bulbs. See you in Summer flowers!
