[GSBN] lime plaster over compressed earth blocks

[Derek Stearns Roff]

Tell us more, Bruce.  How much of plaster is left on the wall, and does most of it seem to be sound?  Is he hoping to get advice on patching the holes, preventing the remaining plaster from delaminating, or perhaps removing the remaining plaster and prepping the surface, so that the future layer will be more reliable?  Is there any reason to suspect moisture intrusion into the wall as a cause for the delamination?  Has this been a progressive problem from the beginning, or did it pop up recently?

Frank Meyer lives in Austin, and has experience with local clays and lime plaster over clay and adobe, so his experience will be valuable.

I'm trying to help a builder near Austin, Texas with a delimitation problem on a 7 year old building.  He says he has since learned to use potassium silicate as a brush-on stabilizer for the blocks, helps the plaster hang on.

Thoughts?  Experiences?

Austin folks:  I'm coming into town tonight.  Dinner?
