The EPS Cement Sandwich Panel is designed to be an extremely low maintenance wall system that can deliver reliable performance for decades, but a small amount of simple regular care will help you avoid preventable issues and ensure your walls stay in excellent condition for more than 25 years after installation. Unlike natural wood walls that need regular repainting every 3 years or metal siding that can develop rust spots, the EPS Cement Sandwich Panel only requires very minimal attention to maintain its full structural and thermal performance.
The most important regular maintenance task for EPS Cement Sandwich Panel walls is a simple annual visual inspection. Once every year, walk along all exterior walls and check all the panel joints, sealant lines and the connection points between panels and window frames. Over time, exposure to extreme UV sunlight and seasonal temperature changes can cause small cracks to appear in the silicone sealant along panel joints. If you find any cracked or peeling sealant, simply remove the old sealant material, clean the joint surface thoroughly, and reapply new high quality weather proof silicone sealant. This quick and low cost step prevents rain water from seeping into the joint area, which is the only most common cause of long term wall issues.
For the painted surface of your EPS Cement Sandwich Panel walls, you only need to do a full repainting job every 8 to 10 years, which is 2 to 3 times longer than the repainting cycle required for traditional masonry walls. When you do need to repaint, you do not need heavy sanding or surface preparation, just clean the wall surface to remove dust and loose dirt before applying a new coat of exterior wall paint. You should never drill large random holes directly through the EPS Cement Sandwich Panel surface without checking the panel layout drawing first, to avoid damaging the main structural edge reinforcements inside the panel. If you follow these simple steps, you can expect your EPS Cement Sandwich Panel walls to maintain full performance for 30 years or longer.
