A two-component composition including: a) a first component A, including: an aqueous dispersion of at least one polymer P1; b) a second component B, including: at least one hydraulic binder H, and at least one functional compound P2; wherein both components A and B are liquid or pasty and both are prepared and stored separately and mixed directly before application; and with the proviso that the functional compound P2 includes functional groups that chemically react with the aqueous dispersion of the first polymer P1 to form cross-linked and/or chain-extended polymers. The composition is highly suitable cementitious adhesive, joint sealant, casting composition, or coating and shows improved mechanical properties, adhesion properties, and resistance as well as minimized plasticizer migration problems. |
