Specs:
- Garage floor is cement
- 24'x32' (except where the car will park.)
- far side is approximately 6"lower than the other. (~1° slope)
- large crack running the full length.
- a number of smaller cracks.
- some old oil stains.
What I've got so far:
- Power wash the floor of the garage.
- Scrub and remove oil stains. (What do I use?)
- Let fully dry. (How long?)
- Use angle grinder with concrete cutting wheel to clean up and widened crack.
Update: Recommended to use a concrete saw instead. - Fill crack. (Bondo All Purpose Putty?)
- Update: Use a Bonding Agent between the layers. (Something like Latex Drylok Bonding Agent?)
- Use something between 2×4 studs/base plate to separate the cement and the wood and keep the cement from filling the stud bay. (Flashing maybe?)
- Caulk cracks at base plate. (Silicone?)
- Build Walls and seal gaps. (Silicone?)
- Mix and pour cement. (What cement should I use keeping cost and simplicity in mind?)
- Tool the cement so it's level.
Notes:
- planning to use epoxy coating for floor.
- prefer to use something that is simple but cost effective. (If you can call any of this simple)
- will not pour where car is going to park.
- will be both a workshop and a garage.
Questions:
- Am I missing any steps?
- What are good products to use given the depth of the pour goes from 0" to 6"?

I’ve used Gypcrete over concrete slabs and various wood structures.
I think it’s rated up to 8” thick per lift. However, it can’t be walked on, etc. because it will wear. You’ll need provide a covering.
It goes in like tomato soup, so it will seek its natural level. It hardens in a couple of days.
