Abstract : A large-scale field application to evaluate four currently specified exterior concrete and masonry paints has been undertaken. The paints were applied on the ocean side of a large concrete building in such a way that each paint received the same set of slightly varying exposure conditions. Since the ocean side of the test location faces directly south, the paints under evaluation are subjected to natural weathering under the influence of solar radiation and salt spray. Present findings indicate that one of the four paints, a cement-water paint, has an undesirable water absorbing characteristic under exposure to continuous rainfall. (Author)
