Conclusion analysis: meanwhile, the building caulking agent prepared by the invention is adopted to carry out 24-hour water spraying test according to the requirements of national exterior wall waterproof inspection specifications, and the results show that the performances of the examples 1-5 are better than those of the comparative examples 1-3, and the performances of the comparative examples 1-3 are better than those of the 42.5 Portland cement. The original cracks of the walls in the embodiments 1 to 5 have no new water penetration phenomenon, and the mildew spots on the surfaces of the walls are not generated after the observation for nearly 6 months.
