What material does photography use to build the fake wall of the scene?

My home is the same as yours, but if I want to shoot products, I need all white. What I posted was a wallpaper that didn't need big changes and didn't cost much. The most important thing is that I can enjoy myself or you can buy that kind of board. I don't remember, it's all in the building materials market. You can stick background paper or wallpaper on the board, and you can also stick a few pieces on the background floor if you like, thus solving the problems of background and floor. It's convenient to put it away when not in use, it won't destroy the prototype of your room, and other colors can be pasted on the back of the board, so you have another scene to choose from. Generally speaking, 300-500 is enough. If you choose the first method, it may be cheaper. The lens I use is Nikon 18- 135, and the lens I can shoot is not expensive ... I hope what I said is useful to you. Good luck.
