My parents want me to do a mural in their house. The walls are textured. What do I do? Do I sand it down or skim coat it? In my research I found both options. Sanding sounds like it could take awhile, but so does the skim coating. I've already checked to see if they have lead paint on their walls, and they don't.
How would they feel about some very thin butt joints between 4 foot widths? If I was ever to do a full wall sized mural, I would want to paint on Dibond or M-Panel ACM panels rather than on drywall. There are several high tech methods to attach the panels to the wall. By working on the panels you can finish it in your studio then install it when done. The ACM panels come in 48" widths and up to 10 feet in length. Some can be had larger than that if I recall correctly.
Another option is a roll of canvas that fits the wall that can be attached before painting on it, or when the painting is done with Beva 317 liquid adhesive. The Beva would allow removal of the canvas later if desired.
