We just pulled of the wall paper in our office and underneath was black mold on the sheetrock/drywall. What do you do? Is there a wall primer that kills the mold that can be applied or do you have to remove the affected areas? Also if there is mold on the exterior of the sheetrock/drywall can there be more inside of the wall?? Thanks for your help!!!

tear it down and put up new make sure to wear a surgical mask when you do this. Also bleach removes mold. Sheet rock is too porous though.
You have to start over. Good luck.

Best to remove all damaged sheet rock, inspect the interior of the wall to determine cause. If the damage is near a window, you may possibly have water getting in around the frame. Inspect the exterior of the wall as well to determine if there is dry rot. Dry rot can be caused by water getting in from the outside and eventually seeping through to the interior. It's really about finding the source, addressing that then installing new sheetrock once the repairs are done. Be sure to wear protection and isolate the area with plastic sheeting to avoid mold spores from becoming airborne into your other living areas. Turn off your HVAC so that spores do not get into the ventilation. Sometimes a professional is the way to go for health reasons.

Yes it can be internal, if the sheet rock is soft you can bet it is and you should cut out the bad area...the framing may have water damage as well. Replace what you can and what you can't kill the mold with a mixture Clorox and water (50-50) If it's only on the surface, spray the wall with the mixture of Clorox and water. Before you paint, use a primer on the wall and ask the paint people to put the mold inhibitor additive into your paint.

Is there water damage? If so that needs to be addressed first. The mold can be cleaned and killed with Clorox Cleanup. After this has dried use a primer like Kiltz. It helps to prevent mold growth.

You need to replace the drywall if possible. If not they have this stuff called "Killz" it's a primer that retards mold and mildew. It maybe too late but, you can try it if the wall is dry.

mildew on the inside wall is usually a result of high humidity indoors due to the humidifier, poorly ventilated bathrooms and laundry rooms.
The problem is common on perimeter walls of buildeings which are poorly insulated in cold climates in which condensation forms many times on both sides.
Another cause for this to happen especially on frame construction with a sided exterior is the failure to apply a breathable vapor barrier building wrap such as TYVEK which prevents moiture in the air to invade this area.
If this is the problem cost could be a factor in it's remedy!
I hope your renting.

wash it with bleach first, let it dry thoroughly
