While EPS Cement Sandwich Panel is very easy to slot and work with, there are still a few common mistakes that inexperienced workers often make, which can cause unnecessary damage to the panel and affect its later performance. Understanding these mistakes and avoiding them will help you get the best results and make full use of all the advantages of this excellent wall material.

The first common mistake is cutting slots that are too deep. If your cutting depth exceeds 2/3 of the total panel thickness, you will cut through the middle EPS core and damage the cement facing layer on the other side, weakening the overall structural strength of the wall. The recommended maximum slot depth is 1/3 of the panel total thickness, which is more than enough for most common electrical conduits and small water pipes. The second mistake is cutting cross slots or multiple parallel slots that are too close to each other. This will create a weak area on the panel surface, which may crack under external impact later. You should keep the distance between two parallel slots at least 100mm. The third mistake is using a worn-out cutting blade. A blunt blade will pull the cement facing layer instead of cutting it, causing large areas of edge collapse. You should replace the diamond blade in time once you find it is no longer cutting smoothly. If you follow these simple rules, you will get perfect, clean slots on EPS Cement Sandwich Panel every time, and the finished wall will maintain its full strength, load capacity and durability for decades.
