Use | For concrete, render, brick and other alkaline substrates. Guidance for specification option: Apply the first coat of Keim Lotexan by low-pressure spray, working from the bottom of the substrate upwards, firstly in a horizontal manner. After a period of approximately 10 minutes, a further coat should be applied again from bottom to top in a vertical manner, thus ensuring that all facets of the substrate are well coated. It is important that Keim Lotexan is only applied to a dry surface and care is taken to avoid runs, as the material is thin. |
