A view of the inside casita new plaster which is an earthen mix made from the clay rich soil found near the main house. The inside walls of this small casita were almost as worn as the exterior walls which were exposed to the elements for many years. We suspect that perhaps the roof was not but upon the building immediately during construction (in the 1970s) and the therefore became a bit worn. It is simply our educated guess given the condition we found the walls in.
Another issue in the inside of this wall was when mud was applied to the walls in the form of what we suspect was a plaster mix created by the original crew. The mix was incorrect and did not have enough sand in it (if any at all) and what mud which did exist when we came onto the project was heavily cracked and peeling. One condition which could have created such a result was that the mud was applied too thick. We did end up peeling off deep, thick patches of cracked mud during our rather extensive infill coat.
For such a small space we were a bit shocked at how much time we actually needed to do all of the repair work to get the walls inside and out in good enough condition so we could plaster them. Rule of thumb for any project. Repair sooner than later any issues you see occurring on any wall or project. It will save you much time, effort and money in the end! We’ve seen it many times over.
