While the EPS Cement Sandwich Wall Panel is known for its extreme durability, a small number of users have reported minor issues such as fine joint cracks or surface stains after several years of use, most of which can be avoided or fixed with simple daily care. The most common problem occurs when contractors skip the fiberglass mesh tape step between two EPS Cement Sandwich Wall Panel units, leading to tiny cracks appearing as the building settles.

If you find small cracks on your EPS Cement Sandwich Wall Panel, you can simply polish the area with fine sandpaper, fill it with flexible putty, and then apply a new layer of exterior paint to restore the wall to perfect condition. For exterior EPS Cement Sandwich Wall Panel installed in rainy coastal areas, we recommend applying a layer of waterproof coating on the surface once every 5 years, to prevent moisture from seeping into the panel edges and affecting its insulation performance. You should also avoid drilling large holes randomly in the middle of an EPS Cement Sandwich Wall Panel without checking the pre-marked reinforcement positions, to keep the panel’s structural strength intact.

With these simple maintenance steps, a properly installed EPS Cement Sandwich Wall Panel can easily last for more than 60 years, far outperforming the 20-30 year lifespan of many other lightweight wall materials.
