A novel coating for waterproofing and sealing a sewage system structural unit using a styrene polymeric film cast from an organic solvent is disclosed. The coating is easily maintained as damaged areas and imperfections can be repaired by simply applying additional liquid composition to the damaged area, and the liquid composition remelts the existing film allowing the newly formed film to be continuous. In addition, the composition can be applied to structural units in sub-freezing temperatures or to wet surfaces. Novel methods relating to the use of the liquid, chemically resistant coating composition are also disclosed including application to concrete and masonry units used in sewage systems. |
