Abstract: A paste composition, method of use, and building product containing such composition. The composition comprises at least one (preferably two) silyl-terminated polymer resin and a plurality of adhesion promoters. In preferred embodiments, the composition has a paste consistency. In preferred embodiments the paste has a slump between 0 and 20 mm, more preferably a slump between 0 and 10 mm, and most preferably a slump between 0 and 5 mm, and a low water absorption after water immersion. In further exemplary embodiments, the composition further has good bond to dry/damp concrete and other substrates, with and without water immersion.
