Unverified85% confidenceDecision RuleTime unknown
补墙膏干燥后一般会比原墙略白且有轻微反光差，浅色乳胶漆墙面修补后需局部或整墙滚涂同色乳胶漆盖色，仅修补不刷漆几乎必留补丁痕

Unverified浅色乳胶漆浅色不代表遮盖力好，深转浅底墙（如原墙有深色/污渍）需选择遮盖力强的产品，对比比≥0.95为佳，否则需刷2遍面漆以上仍可能透底85% similarUnverified白色乳胶漆墙面直接选带涂料的补墙膏（膏+漆二合一）可免刷漆；但彩色墙、深色墙必须先补白色腻子再单独刷同色漆，二合一产品颜色几乎无法匹配非纯白墙84% similarUnverified二合一免刷漆补墙膏施工最便利，但颜色与原墙存在色差且遮盖力有限，修补面越大越明显；分步腻子+刷漆虽麻烦但整体效果更均匀84% similarUnverified泛黄的旧白墙不要指望用白色补墙膏补出无痕效果，新补处会比老化墙面更白形成亮斑，大面积泛黄建议整墙重刷83% similarUnverified乳胶漆开桶后调色和一次性用完为佳，剩余漆密封保存也易变质结块；同色墙面务必同批次购买足量，不同批次可能存在肉眼可辨的色差83% similar
