TL;DR
Concrete etching risk is the chance of permanently scarring a slab during pressure washing by holding a zero-degree or narrow tip too close, using excessive PSI, or lingering in one spot, which carves wand lines and exposes aggregate. Newer concrete under a year old and decorative or sealed finishes are most vulnerable.
What it means
Concrete etching risk is the chance of permanently scarring a slab during pressure washing by holding a zero-degree or narrow tip too close, using excessive PSI, or lingering in one spot, which carves wand lines and exposes aggregate. Newer concrete under a year old and decorative or sealed finishes are most vulnerable. Professionals control it by using surface cleaners or 25-degree fan tips, keeping the nozzle moving at a consistent height, and testing an inconspicuous corner first, marks from this damage cannot be washed out, only ground or resurfaced.
