House built in 1995 - removed some old wall paper. Wall paper adhesive was super thin, so not really concerned there but got into some material underneath the first layer of dry wall that seemed kind of sus to me.

House was built in 1955. We’ve painted over the ceiling title in the rest of the house but in the utility room, some is crumbling away. Going to get it tested but just wondered if anyone had some thoughts/opinions.

Looks like fiber board to me but I really don’t know
