So, what is your specific question?
Some notes:
1. Thinning of epoxy with acetone is possible. However, last I read, Gougeon Brothers recommended against the practice.
2. Thnning of the epoxy results in a more porous and brittle coating. When coating a surface, the acetone evaporates leaving a porous product behind. Acetone is not part of the epoxy reaction as I understand it. However, not certain the effect when using to fill a crack. You may end with a weak joint in the crack if the acetone cannot escape.
3. I would suggest using a low viscosity epoxy or one especially formulated for filling cracks.
