Use | For weathered stone and substrates with lower alkalinity. Guidance for specification option: Keim Lotexan-N is optimized for application onto pH neutral surfaces. Apply the first coat of Keim Lotexan-N 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, this time in a vertical manner, thus ensuring that all facets of the substrate are well coated. It is important that Keim Lotexan-N is only applied to a dry surface and care is taken to avoid runs, as the material is thin. |
