Resurfacing products such as this have their uses and can be surprising durable. We typically use Ardex CD but I can't say that the Re-cap doesn't work just as well. A couple caveats however;
If the underling concrete isn't sound, stable and prepped properly, no topping is going to perform very well. Also, the video shows a fairly smooth substrate, which results in a smooth topcoat. This stuff goes on pretty thin and will telegraph even the smallest imperfections. Patching, grinding and leveling the substrate is time well spent. Finally, I'm not sure I'd trust any of these products to stay down on a smooth concrete surface with out some profiling of the surface.
