See how a contractor‑grade surface cleaner delivers a smooth, even finish on stained concrete.
Pretreating the patio with targeted detergents helps break down deep stains, tannin marks, algae, and embedded dirt before surface cleaning. This step ensures the concrete lifts evenly,
brightens more, and finishes without blotchy spots. Professional pretreatment is the key to getting the best results on patios, driveways, and walkways in San Antonio.
This video shows how F9 BARC removes rust, fertilizer stains, and battery acid burns from concrete. As a Certified F9 Authorized Applicator, we use the same professional process to safely restore rust‑stained surfaces across Northeast San Antonio.
