Even though EPS Cement Sandwich Wall Panel is a very forgiving easy to install material there are still a few common installation mistakes that can lead to unnecessary problems later on if you do not pay attention. The most frequent mistake that inexperienced installation teams make is not leaving a small 5mm expansion gap between the top of the EPS Cement Sandwich Wall Panel and the ceiling slab to accommodate minor structural movement. If you push the panel too tight against the ceiling the panel will have no space to expand when the temperature rises which can cause unwanted bending or surface cracking issues. Another common mistake is using ordinary cement mortar instead of the special recommended polymer adhesive to bond the joints between EPS Cement Sandwich Wall Panel units. Ordinary cement mortar is too rigid and will crack very quickly when there is minor movement between panels which leads to visible cracks appearing along the wall joints after a few months. People also sometimes forget to install the anti crack fiberglass mesh tape over all the panel joints before applying the finishing putty which is a critical step to prevent joint cracking. By following the official installation guide carefully and avoiding these simple common mistakes you can make sure that every EPS Cement Sandwich Wall Panel you install will remain perfectly smooth and crack free for decades.
