The problem of wall pollution refers to the damage caused by the improper operation of the builder when the epoxy floor paint splashes onto the wall. Even if the damaged wall is repaired in time, it will be difficult to restore as before. The residual defects not only seriously affect the beauty of the wall, but also cause customers to question the professionalism of the floor paint manufacturer. Therefore, it is a crucial detail to do a good job of wall protection measures in floor paint construction. So, how can we avoid polluting the walls? Or, when the walls are polluted, how should we clean them up?一般来说，墙面污染来源主要有2种：一是交叉施工导致地面泥浆或地坪漆、着色剂等溅到墙面上;二是在施工前，施工人员没有对已完工墙面进行有效保护，施工时也没有留心，导致地面材料沾染到墙面。
Generally speaking, there are two main sources of wall pollution: first, cross-construction causes ground mud or floor paint, colorants and other splashes on the wall; second, before construction, the constructors did not effectively protect the completed wall, nor did they pay attention to the construction, leading to the surface material contamination to the wall.针对交叉施工导致的污染问题，施工团队只要建议业主让地面施工提前进行，避免与其他工种比如水电、墙面一同作业，就能轻松解决。
In view of the pollution caused by cross-construction, the construction team can easily solve the problem by recommending that the owners make the ground construction ahead of schedule and avoid working with other types of work, such as hydropower and wall.而对于因墙面保护不到位导致的污染，就需要地坪漆厂家在施工地坪漆前，采用塑料薄膜，或装修专用保护膜、美纹纸等对已施工完的墙裙、樯柱脚进行覆盖保护，待完工后撕去保护膜即可。当然，如果是采用滚涂、镘涂方法施工环氧地坪漆，操作足够小心的话，也可以不用保护膜，具体还需依据实际情况来判断。
For the pollution caused by inadequate wall protection, floor paint manufacturers need to use plastic film, or decoration special protective film, decoration paper, etc. to cover and protect the completed wall skirt and pillar foot, and tear off the protective film after completion. Of course, if the rolling and upsetting methods are used to construct epoxy floor paint, the operation is careful enough, or the protective film can not be used, and the specific situation needs to be judged according to the actual situation.相比施工前的墙面保护，处理污染后的墙面就显得比较麻烦了，若墙面已经发生污染就需要地坪漆施工团队及时补救，用铲子或腻刀铲除污染物，对于难清除的着色剂或地坪漆就用强溶剂型清除剂清洗再用铲子清理干净，等到污染物清理完毕后，马上用砂纸对墙面上部及墙角底部残留进行细致打磨，直至露出原墙石膏或腻子底，再补刷墙漆。
Comparing with the wall protection before construction, it is more troublesome to deal with the polluted wall. If the wall has been polluted, it needs the floor paint construction team to remedy it in time. The pollutants are removed with shovels or putty knives. For the hard-to-remove colorants or floor paint, the strong solvent-type cleaner is used to clean it up with shovels. When the pollutants are cleaned up, sandpaper is used to the wall immediately. The upper part and the bottom of the corner are polished carefully until the plaster or putty bottom of the original wall is exposed, and then the wall paint is repaired.
