The invention relates to environmental-friendly coating, in particular to an ecological shell powder embossment coating and an embossment construction method. The ecological shell powder embossment coating comprises shell powder, hydrated magnesium silicate, vinyl acetate, hydroxyethyl cellulose, polyvinyl alcohol, polydimethylsiloxane, titanium dioxide, propyl alcohol ether, coating wear-resistant hardening agent-aluminum oxide, a nano TiO2 (titanium dioxide)/white carbon black composite photocatalytic material. The ecological shell powder embossment coating has the advantages that the pollution problem caused by 'formaldehyde, benzene, ammonia, radon, an organic compounds TVOC (total volatile organic compound) and alkylphenol ethoxylates' is solved; the problems of yellowing, mildewing, swelling, discolouring, dusting, cracking, low hardness, short service life and generation of large amounts of bacteria after getting damp of a traditional interior wall material are solved. The embossment construction method has the advantages that skin textures of an embossment can reach to a 3D (three-dimensional) effect with bright color, solid figures are realistic and lifelike, people have a feel of be personally on the scene, and a high artistic appreciation value is obtained.
