Abstract: The present disclosure relates to liquid compositions including a (meth)acrylic polymer, a (meth)acrylic monomer, and a maturation agent selected from a metal oxide or a metal hydroxide. The (meth)acrylic polymer can contain a monomer carrying a carboxylic acid function and/or the (meth)acrylic monomer can carrying a carboxylic acid function. The liquid compositions can also contain a dynamic viscosity between 10 mPa·s and 10 000 mPa·s at 25° C.
