The joint treatment between panels is one of the most critical steps that directly affects the final installation quality of EPS Cement Sandwich Panel partition wall. Before carrying out joint treatment you need to clean all the dust and debris inside the gap between two adjacent EPS Cement Sandwich Panels to ensure the caulking material can fully contact with the panel surface. You should use the special caulking mortar provided by the EPS Cement Sandwich Panel supplier to fill the gap completely instead of using ordinary ordinary cement mortar which may cause poor bonding effect. After the caulking mortar is initially cured you need to paste a layer of special anti crack fiber mesh cloth on the joint position to effectively prevent the joint from cracking due to slight deformation of the wall. Many inexperienced construction teams often skip the anti crack mesh cloth step which leads to obvious crack marks appearing at the joints of the EPS Cement Sandwich Panel partition wall after several months of use. Standard and careful joint treatment can make the whole EPS Cement Sandwich Panel partition wall form a complete seamless whole and maintain perfect appearance for a long time.
