water damage and the stains on drywall are the results of a leaky roof. Minor damages can be easily repaired. The following steps will guide you through the repair.

First of all, make sure that the drywall is still attached to studs or framing. If the wallboard is broken or sagging then it will need to be replaced. There may be loose layers of drywall mud or blistered paint but the wallboard is solid enough and secured to the studs. If the wallboard is slightly sagging try to fix it up using drywall screws. Start from the outer edge of the sag. Make sure that the screws must go into the studs and also try not to break it through the surface of the wallboard. Start working slowly from the worst part of the sag using screws to jerk up the board.
By the wallboard secure scrape off all loose layers of drywall paint and mud. Mud and the paint will lose its adhesion just because of that moisture. Scrape the outward until you feel these coatings are solidly involved. A knife with a sharp edge is a good tool for this task. You can read more

Confused - Do you start at "the outer edge of the sag" or "work slowly from the worst part of the sag" which would be the center, not the outer edge?

Hmmm

As a contractor I would be more concerned about possible mold growth forming on the backside paper on the drywall....

As an insurance professional I would be asking myself "is this process restoring the insured to a safe pre-loss condition?"

Hmmmmm

Water can be destructive when it meets the drywall and the interior walls, ceilings it can make them look unsightly and can damage wallboard enough that it collapses and falls apart.


Check the drywall carefully in the area you will repair to ensure it is still attached securely to the studs beneath.


Wipe the sanded area with a slightly damp sponge to remove traces of dust.


Paint over the repair with one or two coats of primer as needed to cover and let it dry.

I think if it looked like that on one side whats the back side look like. Is there insulation that should come out. I would want to use an antimicrobial on the studs behind the drywall. Also replacing the drywall would be preferred by me. Cant put a band-aid on something that needs stitches.

If you have suffered from water damage at your home, then immediate action and rapid relief are crucial. Treating drywall water damage is itself more problematic than the stain.
  1. Before treating the stain, locate its source, which may be a water leak.
  2. To get rid of any potential mold, stir up a 50/50 mix of bleach and water.
  3. Wear rubber gloves and use a sponge to wash the stain or carefully spray the mixture in a spray bottle. The goal here is to kill the mold.
  4. Once the bleach mix has dried, use oil or shellac-based primer to cover the stain. It can be a spray can primer or a traditional brush or roll-on primer. Spray or brush on one coat.
  5. Once the primer has dried, use acrylic or water-based paint and paintbrush to cover the stain. It’s likely the entire ceiling or wall will need a fresh coat to make it match.

A persistent leak can wear a hole from the back of the drywall before it appears in the front. The water leak issue is to be repaired completely to reduce the mold growth with the help of Titan’s mold remediation and restoration specialists.

When water leaks onto drywall it can cause minor damage like stains on the paint finish; very severe damage like bulging in the wallboard; or some degree of damage in between such as bubbling joint compound and peeling tape and paint.
