Concrete resurfacing is the process of applying a thin cementitious or polymer layer over worn or damaged concrete to restore the surface and give it a new look.
Understanding Concrete Resurfacing
Resurfacing uses a thin polymer-modified cement product, usually a fraction of an inch thick, to cover surface problems like scaling, pitting, stains, and light cracking. It can be finished smooth, textured, stamped, or stained to create a new look over the old slab.
When Resurfacing Makes Sense
The slab needs to be structurally sound. Resurfacing can fix surface wear, but it will not fix a slab that is heaving, settling, or badly cracked from movement. If the base has bigger problems, repair or replacement comes first.
Surface Prep Is Everything
Bond is the biggest risk. The slab must be clean and mechanically profiled, usually by grinding or shot blasting, so the new layer can grab onto it. Oil, old sealers, and loose concrete all need to be dealt with before you mix a bag.
Practical Tips for Contractors
Repair cracks and holes first, and follow the product’s mixing and open time limits. Watch the weather, since heat, wind, and direct sun can dry the surface too fast. Seal the finished surface to protect color and wear.
