Exterior concrete leveling compound
I have a small concrete front porch slab (approx 5'x7') that I need to level and wanted to know what exterior leveling compound to use? The compound would be no more that 3/4" at its thickest. I just need a product that will hold up to the Canadian climate and not crack or deteriorate over time, I am not concerend with the finish as a side walk finish if any will do.

I don't think any slab should be perfectly level. You need some minimum slope so rainwater will run off.

Anything that thin is just going to crack.

No topical solution will be long lasting if the maximum thickness is only 3/4" or less.

Are the stairs sinking or falling away from the house? Where they originally poured with some slope?

There might be other solutions to the problem if you provide more information.
