FIELD: powder coatings. SUBSTANCE: invention relates to method for preparing weatherproof powder coatings on metallic or nonmetallic surfaces. Method involves applying powder facing composition followed by its melting and hardening where powder facing composition is used comprising hydroxyl- and/or carboxyl-containing polyester resins with acid structural blocks only or mainly based on aromatic dicarboxylic acids, their anhydrides and/or esters and also polyfunctional low-molecular epoxides as cross-linking agents. Melting and hardening are carried out by effect of NIR-radiation in the nearest infrared spectrum region 800-1200 nm for 1-200 s. EFFECT: improved preparing method. 8 cl, 2 tbl
