Rated 3.0 out of 5.0 by geezer117 Not for thin applications
I used it to smooth over a rough walkway. It was excellent except in one important respect. The sand in the product was very poorly sieved, because small stones were in the mix. So the trowel bumped over those stones and left ridges and drag marks. This isn't a problem for thick applications, but it is not suitable for thin applications.

First, you need to mix this in SMALL batches because it does set up and harden in minutes. I use it exclusively for floor patches in deteriorating red Mexican tile floors. We'd hack out or cut out the bad tile area and remove the subfloor. Then we''d put in a few joist hangers, 2 x4s and scrap plywood to create a new subfloor between the joists, The distance between the desired finished floor height (i.e., the top of the adjoining tiles) to the top of the plywood surface could be as little as 3/4 inches, though we usually went with an inch or so. Then we'd mix red coloring (concrete dye) with the requisite amount of water you will need for the whole batch (I forget how much water it is per box or bag but the data is on the package) and mix up no more than a gallon of mix at a time using a mortar mixer. You can make it buttery. It's a pain in the rear to mix, but it will mix. Then you pour it in or trowel it in as FAST as you can. Get it out of the mixing bucket (use a 5 gallon bucket) asap. If you have a helper the whole thing goes a lot better. So have your helper clean off the residue asap so you can reuse the bucket. Meanwhile use your trowel to smooth out the cement. You can float this stuff to a degree but it's more a matter of using the trowel to smooth it. It starts setting almost immediately. Within a few minutes you can add your final finish. I use the palm of my hands to get a slightly rough finish that is slip resistant. I call it a palm finish (you push down with your palm and sort of move it back and forth a bit... It looks good but wash your hands asap. You can use a coarse brush or other approaches too, but you will have limited time. Keep it a bit damp too - and note that it throws off heat. One guy I trained to do this would finish it smoothly and then use a striking tool (for brick joints) to carefully carve out fake grout joints. The finished product really did look like Mexican tile at a glance.
This might all sound unorthodox but the goal was to replace flooring in restaurants that wouldn't be free to work on until the cleaning crew left (midnight) and could be heavily trafficked upon by 6 am. So this left us about 4 hours to do the demo/removal, subfloor patch up, and cement work. It worked very well for this application and I would expect it to work well for any similar thin shell situation.

You better be a speed demon mortaring machine. Within 20 minutes of mixing, this mortar becomes unworkable. Not recommended for the casual non-professional, and I can't figure out how it would be useful to a professional. You certainly can't mix and use more than a few pounds of it at a time.
