I used to have a leaking roof and now the brown spots are horrible, so before I paint it what should I apply first so the dirty brown wont bleed through the paint and shows again?

    Use a stain blocking primer like Zinsser 123, BIN, or KILZ over the spots before painting. You may want to prime the whole ceiling.

    Prime the surface first. Kilz or Zinners are good and available at a home improvement store. Follow the primer directions before painting over the surface with the desired paint. Depending on the size of the room, your budget and style of your house, you may want to consider "tin ceiling" tiles. They are actually plastic, but look like tin. These can also be found at a home improvement store or Amazon. I have not tried the tin ceiling approach myself, so I recommend reading reviews.

    Use stain blocking primer. Wash down ceiling first with TSP. Prime just the stains and dry brush the edges to feather them out. Then, once that is dry, prime the entire ceiling and allow it to dry. Check to see if you see stains at different times of the day. If you do, prime the visible stains and feather again. Allow to dry. Prime entire ceiling and allow to dry. Check for any stain showing through at different times of the day. If you see anything, repeat process, If not, you should be able to paint successfully!

    I would make a THICK solution of Ajax and vinegar, and apply this to the ceiling. After a few hours, then take this off, and see if this helps.

    Cut the tape out and replace it with drywall mesh tape. Then use some drywall patching compound with a putty knife over it. Let it dry over night. Next day go over the patch with a damp sponge to smooth it out.

    Use Kilz before painting.

    Ok, but if you did want to go with tin ceiling tile approach, you should be able to scrape the popcorn off. It would be very messy to scrape off, but it would give you a smoother surface to start with. Just a thought.

    Did you try spraying the spots with bleach? This really works on white ceiling 's A very fine spray and spots disappear

    You will need to buy a quality primer. Read the back to make sure it will hide water spots. We use BIN, and just spray or paint it on. (Throw away the cheap brush afterward.) Then lightly sand, and then paint.
