The invention relates to the technical field of chemical materials, and specifically relates to a powdery crack filler. The crack filler is composed of the following components in parts by weight: 6 to 12 parts of lignocellulose, 550 to 580 parts of quartz powder with a size of 325 meshes, 20 to 30 parts of ferric oxide pigment, 1.7 to 5 parts of hydroxypropyl methyl cellulose ether, 3 to 5 parts of polypropylene fiber, 3 to 9 parts of water repellent, and 25 to 20 parts of ethylene-vinyl acetate powder. The powdery crack filter does not damage the tiles, and is capable of resisting moisture and water.
