One of the biggest advantages of the EPS Cement Sandwich Wall Panel is that it requires almost no maintenance, but a few simple regular checks will make it last even longer. Once a year, walk around all your exterior EPS Cement Sandwich Wall Panel surfaces to check for any small cracks or chips in the outer cement layer, especially after severe storms or extreme weather. If you find any small damage, just clean the area and patch it with a little cement repair mortar, to stop moisture from getting into the panel core. You don’t need to repaint the exterior surface very often, a high-quality exterior paint coat applied every 8-10 years is more than enough to keep the panel protected and looking new. Never drill large holes through the EPS Cement Sandwich Wall Panel without checking the panel layout drawing first, to avoid breaking the internal structural connectors. For interior panels, you can clean them easily with a damp cloth and mild detergent, no special cleaning products are needed. With these tiny, simple steps, your EPS Cement Sandwich Wall Panel will stay strong and high-performance for 50 years or more, with almost no extra work or cost.
