Transport & Storage: Panels must have protective film on both sides and avoid contact with sharp objects. Store flat, indoors, and dry, away from direct sunlight and heavy stacking.
Installation: Keep the film on until installation. Remove it promptly (usually within 1-2 months) after installation by peeling carefully from the edges to avoid adhesive residue or difficulty in removal caused by prolonged sun/rain exposure.
Cleaning: After installation, clean with a neutral cleaner and soft cloth. Do not use strong acids, alkalis, or abrasive cleaners.
