Step 3: Leveling
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.
