I'm thinking of putting down about 1 cu yd of concrete (2 inch average over 150 feet) to even it up. However, I need to taper from 3 inches to 0. If I put down a filler layer of concrete and then self leveler, first roughing the surface and use a bonding compound, how thin can I leave the taper on the edges? One inch? two inches?
I then intend to even up the whole thing by pouring self leveler over the top. however, 1 cu yd of self leveler is way too expensive.
