To provide a decoration method capable of forming an aesthetically pleasing, newly deposited coating film and holding its finished state over a long period on an existing wall surface having an uneven pattern and comprising an existing coating film of high durability.SOLUTION: The present invention is a decoration method for an aged existing wall surface, the existing wall surface having an uneven pattern on its surface and comprising at least one type of existing coating film selected from an inorganic coating film, an organic-inorganic composite coating film and a fluorine resin coating film. To the existing wall surface is applied an under coating containing a resin component and powder (m) of an average particle diameter equal to or less than 1 μm and/or powder (n) with an oil absorption amount equal to or higher than 100 ml/100 g and an average particle diameter of 2-100 μm, where a total amount of the powder (m) and the powder (n) is 10-250 pts.wt. relative to a solid content of the resin component 100 pts.wt., and a pigment volume concentration is 1-30%. After drying the coating, an upper coating is applied.SELECTED DRAWING: None 【課題】凹凸模様を有し、高耐久既存被膜を備えた既存壁面に対し、美麗な新設被膜が形成でき、その仕上り状態を長期にわたり保持することができる化粧方法を提供する。【解決手段】本発明は、経年劣化した既存壁面の化粧方法であって、上記既存壁面は、表面に凹凸模様を有し、無機質被膜、有機無機複合被膜、フッ素樹脂被膜から選ばれる少なくとも１種の既存被膜を備えたものであり、上記既存壁面に対し、樹脂成分、並びに、平均粒子径１μｍ以下の粉体（ｍ）及び／または、吸油量１００ｍｌ／１００ｇ以上であり、平均粒子径２～１００μｍの粉体（ｎ）を含み、当該粉体（ｍ）と当該粉体（ｎ）の総量が、当該樹脂成分の固形分１００重量部に対し１０～２５０重量部であり、顔料体積濃度が１～３０％である下塗材を塗付し、その被膜の乾燥後、上塗材を塗付することを特徴とする。【選択図】なし
