I want to collect additional samples of an acoustic ceiling for the purpose of having it checked for asbestos. The previous test came back negative but I'm paranoid =)
The procedure as per instructions on my prior collection kit was:
- Spray water (light soap/water mix) while collecting sample.
- Double bag the sample.
What I'm confused on is:
- What are the best areas in the ceiling to take a sample?
- How large of a sample could I be collecting? The test is supposed to be able to detect 1% asbestos by volume.
- How do I patch/seal the area where I took the sample?
Any thoughts? The ceiling is in great condition so far with no cracks or significant abrasions so I want to keep it that way (especially if there is asbestos).

My thoughts on your first question would be to take a sample from a few different rooms, if you can see any differences between color/texture on the ceilings. From asbestos.com:
I'm not sure about the size of sample required, but I don't think you'd need more than a few square inches.
As for patching the ceiling, you should prime the sample spot before painting. After that, you can mix some standard ceiling paint with a texture additive to match the consistency of your original ceiling. Since it's a small area, you can probably get away with using a brush, or possibly a small roller. Or, instead of bothering with texture matching, you could go the easy route and use spray-on popcorn ceiling texture after priming (beware the horrible product reviews though - it might be easier to use a pre-mixed product).
