Repair water leak drywall damage


I had a small leak on one of my skylights (now repaired). I ended up with a small water stain on the drywall, at the connection of the ceiling and wall. The stain is roughly 8x2. The drywall feels solid and firm and doesnt feel damp. The water stain was there for a few months and slowly got worse with each rain. I don't think there was a lot of water leaking, but enough to stain the drywall.

What is the correct way to repair this? Should I cut out the drywall and let this area air-out for a period? Im pretty sure I want to open the drywall to make sure I dont have more damage that I cant see.

Thanks for the assistance.

If the drywall is still solid, I wouldn't think there would be a need to open it up. I'd coat the stain with a solvent based primer - that will seal the stain so it won't bleed thru latex paint.

If you are dead set on opening it up, take a utility knife and cut out the affected area. If you do a decent job of cutting out the old and the drywall is solid - you can reuse that piece to patch the hole.

If it feels solid, I'd just seal it with an oil based primer and then paint, as Mark suggested.

Your call if you want to open this up, Mark gave you a good procedure for that as well.
