Repair or replace your decorative concrete
If your slab is sound but dull, a stain or an overlay can change its look without tearing it out. If it's cracked through, sunk or holding water, the trouble is underneath, and a new surface on top won't fix it. One contractor's guide notes that patches in poured concrete stay visible because aged concrete can't really be matched. On a decorative slab, I usually steer people toward replacing the section rather than patching it.
