resurface aggregate concrete patio

I have a 1980s concrete patio with a very coarse exposed aggregate (3/8" and larger stone). its very painful to walk on and I am curious what my options are.

something similar to this;

can I rent a grinder and go over it or if i need to tear it out and replace it? I also thought about self-leveling in a thin layer overtop but was not sure about durability of that thin layer and its slightly sloped.

any suggestions?

1980s conc was either exposed aggregate & is still used today altho down here its more common to ' seed ' the conc rather'n use a surface retarder/pressure washer.

a grinder'll certainly do the work IF you want to risk knee/back surgery,,, we use a walk-behind scarifier to ' pop ' the graded pebbles out of the surface then apply a broom'd in base coat of polymer-modified cementitious mtl,,, we then applied another smoothing coat of the same material, ' thinfinish ',,, finally a top coat was installed, finished, & sealed,,, we used elitecrete which is only avail to licensed installers,,, there are also many others avail from specialty conc suppliers,,, you won't find anything worthwhile @ apron/vest stores NOR will you find anyone who knows wth they're doing

o'lays work on conc, not stone,,, no respectable pro would choose self-leveling stuff either

would be a helluva lot less expensive to buy everyone flip-flops
