GRG walls typically do not require maintenance after completion and delivery, but the following points should still be noted during use:

1. Maintain indoor ventilation. Try to keep the temperature and humidity inside consistent with the external conditions.

2. Avoid heavy objects impacting the walls. Mild impacts may leave marks or pockmarks on the walls; when the impact force exceeds the larger fracture load of GRG products, it can cause wall cracking, and in severe cases, it may lead to wall detachment.

3. When cleaning walls, minimize the use of wet materials. Contact with moisture may cause a chemical reaction on the GRG wall surface coating, leading to discoloration; opt for soft, dry items for cleaning as much as possible.

4. In the event of wall damage due to external forces, the damaged areas can be trimmed and repaired. Once the repairs are completed, the wall can be restored to its original condition without leaving any traces.
