Neighbor in the pool deck refinishing business just now says he does not use acid anymore because the drying time using water is expensive.
He grinds, vacs and blows.
He did say acid works fine if you power-wash before and after. Before the final power wash you hose out the spent acid and broom wash with buckets of TSP.
