My apartment building is very old. It was built in the 1960s. I want to mount my projector in the ceiling but it is a popcorn ceiling, and an old building, so I am worried about asbestos. Although the building is old, there exists a few new (within 5 years) ceiling lights and the kitchen cabinets and appliances are updated. I attached a picture of the ceiling, it looks new. There is already a area that someone at one point patched up. Based on these circumstances, I am fairly certain there is no asbestos. However I have associated the words 'popcorn ceiling' with 'asbestos' so I am here hoping someone else can offer an opinion. I know I can get it tested, but is it necessary? Also, I imagine the test is only effective if I sample the entire depth of the wall? What if they just covered an old layer of wall with new drywall?
