If your car wash bay walls are high maintenance, it could be because of the choice of your wall paneling material. The choice of wall material determines your long-term maintenance costs, safety, and customer experience. Car washes have a harsh environment, combining high-pressure water, soaps, extreme humidity, and road grime. That is why operators spend huge budgets on state-of-the-art water reclamation and pump systems, only to cut corners on their building materials. Choosing the wrong surfaces for your facility could lead to scraping mold off peeling paint, replacing waterlogged drywall, or stripping off rotten FRP.
