The Dunwell procedure for determining the water permeability of masonry walls was modified so that it improved reproducibility, decreased the testing time from 3 to 4 days to less than one hour and did not mar the painted surface. These improvements resulted from the elimination of the possibility of air entrapment in the reservoir and finding a sealant that produces a leak-free system immediately and could be washed off with common solvents.
