TL;DR
A concrete overlay is a thin, polymer-modified cementitious topping, from a quarter inch to about two inches thick, bonded over an existing slab to renew a worn, spalled, or stained surface without demolition. It can be broom-finished, stamped, or stained, making it popular for patios, pool decks, and garage floors.
What it means
A concrete overlay is a thin, polymer-modified cementitious topping, from a quarter inch to about two inches thick, bonded over an existing slab to renew a worn, spalled, or stained surface without demolition. It can be broom-finished, stamped, or stained, making it popular for patios, pool decks, and garage floors. Success depends entirely on the base slab being structurally sound and properly prepared by grinding or shot-blasting; an overlay over active cracks or settling concrete simply inherits those failures.
