APPLICATION OF CERESIT R 740

Apply a thin, uniform priming coat with a suitable roller (see Technical Data). Avoid pooling of excess primer on the surface. When sealing the substrate against capillary rise of moisture or residual moisture in concrete floors or cement screeds, it is always necessary to apply a 2nd coat cross-wise after the 1st one has dried (after 24 hours at the latest).
