Zusammenfassung:	To provide an aqueous coating material having excellent coat strength, adhesion, rust-prevention properties or the like.SOLUTION: An aqueous coating material contains a coat formation component and a powder component. The coat formation component contains an aqueous epoxy resin emulsion as a resin component, and a coat to be formed has a gel fraction of 10% or more. The powder component contains an antirust pigment, and calcium carbonate. Relative to the resin component 100 pts.wt., the content of the powder component is 50-300 pts.wt. In the powder component, the content of the calcium carbonate is 30-90 wt.%.SELECTED DRAWING: None 【課題】塗膜強度、密着性、防錆性等に優れた水性被覆材を提供する。【解決手段】本発明は、被膜形成成分、及び粉体成分を含む水性被覆材であって、上記被膜形成成分は、樹脂成分として水性エポキシ樹脂エマルションを含み、かつ形成被膜のゲル分率が１０％以上であり、上記粉体成分は、防錆顔料、及び炭酸カルシウムを含み、上記樹脂成分１００重量部に対し、上記粉体成分を５０〜３００重量部含み、上記粉体成分中に、上記炭酸カルシウムを３０〜９０重量％含むことを特徴とする。【選択図】なし
