Method for influencing moisture content and migration in building materials

摘要

The moisture content within, and moisture flow in and out of, porous building materials such as masonry, brick, concrete, and mortar, can be affected by coating the building material with polyvinyl alcohol, or by incorporating polyvinyl alcohol into the building material. The resultant control of moisture movement can influence the suction of the building material, leading to improved bonding with adjacent building material, and can also retard efflorescence.
