APPLICATION

Surface should be cleaned, dry and free from loose particles, oil, grease or other foreign materials. Deep contaminated concrete should be thoroughly cleaned by wire brush. Mix all the pre-weighed  Pack-A with the pre-weighed Pack-B  and stir thoroughly preferably with a low speed electric drill or paddle mixer for 2-3 minutes.. Apply a thin layer of Hind Bond EBA with brush to the existing surface, working well into the substrate. Place fresh concrete/mortar while it is still ‘tacky’.
