PROBLEM TO BE SOLVED: To obtain an additive for treating a surface, capable of being readily dispersed in a surface-treating agent while keeping the surface-modifying effect possessed by a conventional surface-treating agent obtained by using silica or the like, excellent in redispersibility after preservation, and further excellent in prevention of the surface from lacking. SOLUTION: This additive for treating the surface comprises polyvinyl chloride resin particles having 0.1-40μm average particle diameter, and capable of providing 0.1-70μm resin-averaged particle diameter and <150μm maximum diameter when 100 pts.wt. dried powder of the particles is formulated with 60 pts.wt. 2,2,4-trimethyl-1,3-pentanediol diisobutylate, and the formulated product is kneaded by using a dissolver-type mixer at 25 deg.C at 800 rpm for 3 min. The additive of 1-50 wt.% is included in the composition for treating the surface.
