1. Is there formaldehyde in wall covering?

Generally speaking, the wall coating itself is environmentally friendly and non-toxic.

It also depends on what auxiliary materials are needed in the construction process. Wall coating itself does not contain formaldehyde and is considered as a green material. However, in wall covering, it is necessary to stick it on the wall with glue. As long as it is glue, there will be formaldehyde and so on.
