The invention discloses a caulking anti-crack mortar comprising the following components, by weight: 10-30 parts of calcined gypsum, 5-15 parts of cement, 50-75 parts of sand, 8-20 parts of fly ash, 1-5 parts of mineral powder, 1.5-3 parts of re-dispersible latex powder, 0. 2-0.5 parts of a water-retaining agent, 0.5-3 parts of an extender, 0.5-3 parts of an activator, 0.1-0.3 parts of polypropylene fiber, 0.15-0.2 parts of a water reducing agent, 0.2-0.5 parts of a waterproof agent, and 0.02-0.2 parts of a retarder. The mortar has the advantages of simple preparation and convenient construction. The prepared caulking anti-crack mortar has high bonding strength, and does not shrink, such that the flatness of a joint is ensured, and cracking and falling phenomena are avoided.
