Abstract

The invention provides colored decorative paint difficult to fall off, and relates to the field of building paint. The colored decorative paint difficult to fall off comprises primer, decorative paint and protective paint, and the spraying steps are as follows: carrying out surface treatment on a wall surface to be sprayed, smearing putty, troweling the putty, waiting for drying, and preparing the primer and a brushing tool; after the putty is dried, the primer is brushed on the wall surface through a brushing tool, the brushing thickness is 2-3.5 mm, waiting is conducted for 30-50 min till the primer is completely dried, meanwhile, decorative paint is blended, and ground color decorative paint and colored decorative paint are formed.
