DH applied the Aqua Mix Enric'N'Seal several days ago and it really works!! Just wanted to give an update as several GWers have e-mailed me with problems like I had at first with a grout way lighter than the sample stick color. Here are the pictures. First is the floor before the enhancer/sealer was applied. Grout way lighter than we wanted.
This is the floor when wet. You can see how the grout darkens up.
This is the floor after the Aqua Mix has been applied. Much better. We like it!
