The self leveling material is very good. You MUST use it according to the instructions.

Anything over 1/16" out in 4 feet should be addressed- IMO.

I like to check the subfloor first. Hunt for high spots. Punch down the nails and using a power planer remove a layer of wood. I attach a shop vac onto the planer exhaust because it is crazy messy.

After the Hardiebacker is installed, hunt for the low spots and mark them with a crayon. Coat those areas with the Level Quik primer.

Mix the Level Quik to the consistancy of pancake batter.
Pour it into the center of your low depression and using a straight edge that will span the depression, "work" the leveling material over the low spot.
Smooth out the edges with a plastering trowell... Feather them.

Allow the material to set-up overnight even though it says you can work on it sooner. it really needs the extra time.
