The invention discloses a high-crack following epoxy coating for concrete, a coating and a preparation method and application of the high-crack following epoxy coating. The high-crack following epoxy coating comprises a component A and a component B, wherein the component A is prepared from G-clay modified epoxy resin, polydopamine, a polymer elastomer, a wetting dispersant, a grafting coupling agent, an anti-settling agent, pigment filler, butanol and xylene, and the component B is prepared from a flexible curing agent, butanol and xylene. And uniformly mixing the component A and the component B to prepare the high-crack following epoxy coating for concrete. The invention further discloses a high-crack following epoxy coating formed by curing the high-crack following epoxy coating for the concrete. The high-crack following epoxy coating for the concrete and the high-crack following epoxy coating for the concrete, provided by the invention, have excellent high-crack following performance and have application
