One of the biggest advantages of EPS Cement Sandwich Panel is that it comes with an almost flat, factory-finished surface straight out of the packaging, requiring very little extra preparation before final decoration work. After installing EPS Cement Sandwich Panel, you only need to fill the small joints between panels with special cement joint filler, then apply a thin layer of anti-crack mesh tape across all seams to prevent any minor cracking that can occur from natural building movement. Once the joint filler is fully cured, you can apply a very thin skim coat of finishing putty across the entire wall surface, and after light sanding, the wall will be perfectly smooth and ready for any decorative treatment. You can apply standard interior latex paint directly to EPS Cement Sandwich Panel surfaces, install wallpaper, or even paste ceramic tiles for kitchen and bathroom areas using regular tile adhesive. The high strength calcium silicate surface of EPS Cement Sandwich Panel creates an excellent bonding base that ensures paint, wallpaper, and tiles adhere very firmly and will not peel off over time. This simple finishing process eliminates the need for the thick, messy layer of cement plaster that is required for traditional brick walls, saving huge amounts of time, labor, and finishing material costs on every project.
