The grout I used doesnt really need to be sealed, but even though granite is hard and not very porous, It is a stone, it is still porous, ...
Step 3: Leveling
I could have used shims to level everything out before hand... But whats the fun in that...
Soooo After securing the backer board and finishing up for the day, the next day I realized that I had not checked the level beside the dishwasher... The answer?
It works like a charm- I had to "build" a duct tape form for the front besides the dishwasher and tape off the back to make sure none of the concrete dripped behind the dishwasher.
Mix up the mix so its a water consistency. (It dries quickly). Spread it out and let it dry.
You could have skipped this step by putting shims under the ply, or between the ply and cement board.
