The results of water permeance tests on twelve walls before and after coating with a proprietary clear water repellant are reported. Half of the single-wythe walls were brick; and other half, normal-weight concrete masonry units. Half of the walls used masonry cement mortar; the other half, portland cement-lime mortar. Comparison of results revealed a significant reduction in the amount of leakage, an increase in the amount of time required to achieve maximum rate of leakage, and a decrease in the percentage of damp area as a result of the application of the coating. The walls will be retested after six months of outdoor exposure.
