Abstract: A method for coating a surface, including the steps: a) applying a first layer of a moisture-curable composition onto a surface, b) optionally letting the applied moisture-curable composition cure into a dried first layer, c) applying a second layer of the moisture-curable composition onto the optionally dried first layer, wherein the moisture-curable composition includes: between 20 and 50 wt.-%, preferably between 25 and 45 wt.-%, based on the total weight of the composition, of at least one organic polymer which is liquid at room temperature and contains reactive silane groups, and between 10 and 30 wt.-%, preferably between 15 and 25 wt.-%, based on the total weight of the composition, of at least one polyether PE having between 2 and 6 ether oxygen atoms and is free of hydroxyl groups; and at least one curing catalyst for reactive silane groups. The method yields a multilayer coating with high intercoat adhesion.
