I have a buddy who says his brother muds over popcorn ceilings all the time. I've asked him a couple of times, but he hasn't gotten me any specifics about the process and materials.
I want to replace our popcorn ceilings with a skip-trowel finish, but I'd rather not take the popcorn down if I don't have to because it's 10% asbestos (I've had it tested).
Has anyone here successfully finished over a popcorn ceiling? Are there any special materials or preparations needed? Primers,...?
Thanks for any info you can provide.
