While the EPS Cement Sandwich Wall Panel is very easy to work with, a few simple mistakes during handling and installation can lead to problems later on. The first big mistake is dragging the panel across rough ground when moving it, which can scratch the outer cement layer and create weak points that let moisture seep in. You should always lift and carry the EPS Cement Sandwich Wall Panel vertically, or use a small cart with soft padding to transport it across the construction site. Another common error is skipping the expansion gap between the top of the panel and the ceiling slab, which can cause the wall to crack when the building shifts slightly with temperature changes. Many new contractors also use regular cement mortar instead of the specialized panel adhesive for joints, which creates gaps that break the airtight seal of the EPS Cement Sandwich Wall Panel. Finally, never hang extremely heavy items like large water heaters directly on a single panel without adding a reinforced backing frame behind it, to prevent the panel from bending under excess weight.
