Hablab whitewash testing

Determined that thick 2 to 1 lime/water ratio is too thick and cracks in some areas. Prepping with misting the adobe layer before limewashing definitely reduces cracking. We are also testing two recipes for tomorrow. One that is 4/3 Lime/water. The other that is 1/1. We will test both of these to see which works better.

Tested different whitewash formula. it appeared that thick lime wash was less tolerant of some areas of the wall and was peeling back at some points after some time had passed. We applied a thin whitewash with the consistency of cream or milk at the end to different parts of the wall to see if we could avoid the peeling problem.
