Yes, you can set up the screen on various surfaces. 

Please refer to the recommendations below：

• Grass – Ideal for setup, as you can securely anchor the frame using ground stakes.

• Dirt or soil – Also ideal; ground stakes can be used to provide stable support.

• Concrete or pavement – Ground stakes cannot be used; instead, place water bags on the base for stabilization.

• Beach sand – For best stability, use both ground stakes and water bags.

Important:

To prevent damage or instability, avoid placing the screen on surfaces with:

• Sharp rocks or hard debris

• Broken glass or metal pieces

• Thorny plants or vegetation

• Uneven terrain or steep slopes
