I have some exterior concrete stairs that were finished poorly. The treads are back-sloped and pools sit consistently on the treads in the fall/winter.
I am having the tread surfaces ground down so the water can drain. The exposed smooth aggregate surface now becomes a slip hazard instead of the ice that would have formed in the puddles.
What product would work to coat concrete in an exterior application that would hold up over time? or is there something else I could do to make the concrete surface non-slick once it has been ground down?
I suppose I could look at installing metal or rubber grip strips. Ideas?
