   With any of the leveling compounds the floor must be clean and free of paint and chemicals to obtain adhesion.

   The amount of water to mix with these compounds is critical, and therefore the mixing proportions must be followed exactly.  Water must be measured, not added by eye.

   Also, being self leveling, it will find any cracks and run down through them, so any cracks, such as around the perimeter, have to be filled with something like backer rod first.

   Could I use the same stuff to repair a cracked and sagging corner of a garage apron?  It's the corner between the overhead door and the sidewalk, foot traffic only.

   I'd fill the crack (caulk?), and build a 'frame' to control the edge, but the apron needs to have some slope.  Is the self-levelling quality of this product going to make this a bad idea?

   I don't think the leveling compound I suggested would be rated for exposure to the weather.  And it is truly leveling; you couldn't make it slop if you wanted to.

   Ardex sd, followed by feather finish has my vote. It's a sure case of you get what you pay for, as Ardex isn't the cheapest.I've tried to substitute with cheaper Quickcrete and Armstrong products, don't bother. The effort of use and trouble free results from Ardex over the other brands more than pays for it's self. Not recommended, but I've seen both SD and feather used interchangeably to depths of 2" in multiple lifts, no primers, and minimal surface prep with no problems. Flip side I've seen the Quickcrete version in green square tubs used to the letter of manufactures specs on 500'sf of hallway separated and cracked within 2 weeks.

   why did the apron sag?
   If the substrate is not solid a leveller will not do much over time

   There is quite probably a reason that slab is pitched towards a French drain; you should consider the consequences of leveling it before you go ahead.
