While EPS Cement Sandwich Panel is very easy to install, there are a few common mistakes that inexperienced construction teams sometimes make that can affect long-term wall performance, and they are all very easy to avoid. The first mistake to avoid is not leaving a small 5-10mm expansion gap between the bottom of the panel and the floor, and between the top of the panel and the ceiling. Without this small gap, natural building movement and temperature expansion can cause the panel to buckle or crack over time. The second common mistake is not using the special anti-crack joint filler designed for EPS Cement Sandwich Panel, and instead using regular cement mortar that is too rigid and will crack easily at the panel joints. The third mistake is cutting the panels too short, leaving large gaps that have to be filled in with messy cement, instead of taking accurate measurements before ordering panels to get perfect factory pre-cut dimensions. The fourth mistake is hanging extremely heavy objects directly on a single panel without using anchor bolts that extend through the panel into the embedded steel bracket behind it. When you follow the official installation guidelines, take accurate measurements, and use the correct recommended joint materials, you will get a perfectly installed EPS Cement Sandwich Panel wall that will perform flawlessly for decades.
