After stopping active water leaks, the surface of the liner was pressure washed, and 1 mm thick coating of Cem-Kote Barrier Cote 100 spray applied and brushed. The coating was let to air cure, before cleaning the surface using pressure water, and one coat of Cem-Kote Flex CR 1 mm thick, was spray applied and brushed to eliminate possible pinholes. Please ask for excellent bond test data.
