Method for Sealing Surfaces

A method for sealing a building surface or roof using a one-component, moisture-curing coating composition (C) comprising 5% to 25% by weight of one or more silane-terminated polymers (P) having end groups of the formula (I)

• ˜O—C(=O)—NH—A—Si(OR1)xR23-x (I),
• in which
• A is a linear or branched alkylene group having 1 to 10 carbon atoms,
• R1 is a linear or branched, optionally halogenated alkyl group having 1 to 10 carbon atoms,
• R2 is a linear or branched, optionally halogenated alkyl group having 1 to 10 carbon atoms, and
• x is 1, 2 or 3,
• 1% to 80% by weight of one or more fillers (F),
• 0.1% to 10% by weight of one or more water scavengers (W),
• 0.01% to 5% by weight of one or more curing catalysts (K),
• 0.01% to 10% by weight of one or more adhesion promoters (A),
• where aminosilanes used as curing catalyst (K) in amounts of 0.5 to 5% by weight can simultaneously serve as adhesion promoters (A),
• and optionally further substances customary in moisture-curing coating compositions, the amounts by weight adding up to 100%,
• with the proviso that the coated surface is sealed against the penetration of water or water vapor.
