so it's may be correct; but don't rely on this:
The asbestos is fine as long as you don't disturb it. Just cover it up.
You can remove it and start over:
If you do it yourself, (remember the face mask, gloves, eye protection, etc) you can do it, you will just have trouble getting rid of it.
You can hire an Absestos Specialist.
Good luck and may God bless
