Came home from work today determined to do some work.
So I cut the floor to length... 15° on the back 18° on the front

Then I figured I'd try the gripper on a large surface, i.e. the inside of the wall.

I think it turned out pretty good. In the past I've used 7 oz canvas, and it shows all the imperfections. The 10oz canvas I got this time does a much better job at hiding the imperfections.
I didn't size it, so it's stretching itself taught. Also, I did not put gripper on the top yet. I didn't want to pull the canvas away from the foam and cause bubbles. Once the gripper has dried I'll do all the waterproofing stuff.
