PROBLEM TO BE SOLVED: To provide an antibacterial floor face in which a noble metal antibacterial component is present over the whole of the floor face by applying an antibacterial coating material for flooring using a resin as the main agent and in which a noble metal antibacterial component is present into a coating film after application at a high concentration.SOLUTION: Using a liquid coating material containing one or more liquid coating materials, a volatile coating solvent dissolving the coating materials and fulvic acid captured with a noble metal salt, and in which the fulvic acid captured with a noble metal salt, an oily antibacterial coating for flooring dissolved into the coating solvent is formed, and the antibacterial coating for flooring is applied to form a coating. In the antibacterial floor face, the noble metal salt is distributed over the whole of the thickness of the coating.SELECTED DRAWING: None【課題】樹脂を主剤とし、塗布後の塗膜中に貴金属抗菌成分を高濃度に存在するフローリング用の抗菌性塗料を塗布して、床面の全体に貴金属抗菌成分を存在させた抗菌性床面を提供する。【解決手段】１以上の液体の塗料材料と、この塗料材料を溶解する揮発性の塗料溶剤と、貴金属塩を捕捉したフルボ酸と、を含み、貴金属塩を捕捉したフルボ酸を溶解した液体の塗料材料をもちいて前記塗料溶剤に溶解した油性のフローリング用抗菌性塗料を形成し、フローリング用抗菌性塗料を塗布して塗膜を形成する。本発明の抗菌性床面は、貴金属塩が塗膜の厚さ全体に分布していることを特徴とする。【選択図】なし
