Apply by brush to clean degreased surface and allow to dry. Avoid excess application and ‘ponding’ in poorly drained areas. The zinc takes on a black coloration within about 5 to 10 minutes under normal conditions of temperature and humidity. The surface should then be rinsed with clean water. The black coloration should be unaffected by washing. Any areas still showing a bright galvanised surface indicates the presence of contamination. Degrease any such areas and re-apply the T-Wash solution.
