Constant exposure to water can damage masonry surfaces like brick, stone, and concrete in a short period of time through freeze and thaw cycles. Unsealed concrete acts like a sponge for water, which can lead to mold and mildew growth. Commercial Painting Services evaluates masonry to determine the proper cleaners and sealers needed to waterproof surfaces, stop mold and mildew, and prolong the life of brick and concrete materials for commercial and industrial buildings.
