环氧地坪漆涂料工程翻修的两种原因，一是原有涂环氧地坪漆层的陈旧、老化：二是更新的需要。 旧环氧地坪漆涂膜的清除需要了解旧涂膜的老化程度与新环氧地坪漆涂层的相容性，对严重老化的环氧地坪漆涂层可用水浸泡、冲洗后用油灰刀铲除。溶剂型地坪漆涂料形成的地坪漆涂层表面致密，须用钢丝刷或电动砂轮等机械方法剔除。 对地板漆涂层并未老化，仅因更新需要而进行翻修的地坪漆工程，主要考虑新老地坪漆涂层的相容性.相容性好的话，只须将表面进行清洗，待干燥后进行地坪漆涂饰施工。如相容性差，在重新涂饰过程中，原地坪漆涂料易起皮，脱落，则旧环氧地坪漆涂膜应按上述方法全部清除。
There are two reasons for the renovation of the epoxy floor paint project, one is the old and aging of the original floor paint layer, the other is the need for renewal. Removal of old floor paint coating needs to understand the degree of aging of old coating and the compatibility of new floor paint coating. For serious aging floor paint coating can be soaked in water, washed and removed with a putty knife. Solvent-based floor paint coatings form a dense surface, which should be removed by mechanical methods such as wire brushes or electric grinding wheels. The compatibility between old and new floor coatings should be taken into account in the renovation of floor coatings which are not ageing. If the compatibility is good, only the surface should be cleaned and the floor coatings should be painted after drying. If the compatibility is poor, in the re-painting process, the original floor paint coating is easy to peel off, then the old floor paint film should be removed according to the above method. 一般情况，同种高分子成膜物质都具良好相容性。溶剂型涂料形成的地坪漆涂层容易在上面覆盖溶剂型地坪漆涂料，水溶型及水乳型地坪漆涂料情况比较复杂，必要时可在旧地坪漆涂层上进行小面积试涂，然后再进行下一步的施工。
In general, the polymer film forming material has good compatibility. Solvent-based floor paint coatings are easy to be covered with solvent-based floor paint coatings, water-soluble and Water-Emulsion Floor paint coatings are more complex, if necessary, can be used on the old floor paint coatings on a small area of trial, and then the next step of construction.
