Mold on Plaster Wall
We have a problem with knockdown texture coming off a plaster wall.
About 2 years ago we wire-brushed a plaster wall and removed any loose material. We textured the wall with knockdown and then it was painted.
As a result of a roof leak, which has been repaired, moisture caused the texture to fail in areas.
The moisture came out of the plaster underneath the texture and paint, causing the surface to bubble. As you can see in the photo there is mold.
We also found visible traces of surface mold on the plaster when we removed the loose texture and paint.
We believe the mold is on the surface and can easily be removed, killed and sealed. However, I'm wondering it we should take a chunk out and see if the plaster is laced with mold as well.
I would appreciate your feedback on if it is possible to apply something to the wall then texture it again. I found it strange that the water/moisture has apparently run down between the outside brick wall and through the plaster before being trapped under the texture and paint. The customer says he never saw any sign of water on the walls painted surface.
I'm also worried that there is lingering moisture in the plaster wall that could cause our texture to fail again. The texture in areas unaffected by moisture is very solid on the wall.
Thanks,
