Abstract: A description is given for an anti-drumming composition comprising a polymer dispersion comprising at least one dispersed (meth)acrylic polymer obtainable by emulsion polymerization of radically polymerizable (meth)acrylic monomers, a high density filler mixture and a specific dispersing aid, wherein the anti-drumming composition has either a volume contraction or only a very low volume expansion after drying.
