其实这是一个关乎新环氧地坪施工后的质量问题的关注，影响老旧无锡环氧地坪重施工之后的质量因素，主要就集中在砼层是否仍具有足够的使用价值上，如果砼层性能已经下降到不符合新环氧地坪施工的强度要求，那就需要重建砼层再施工环氧地坪漆。前面关于停车场环氧地坪漆施工的问题我们已经介绍了很多，基本上是以新建建筑的全新停车场所作为介绍的基础，但是在停车场环氧地坪施工项目中，老旧环氧地坪的翻新和重建，其实是占总项目的较大比例的，所以这里我们介绍一下两者中主要的区别。

In fact, this is a concern about the quality problems after the construction of new epoxy flooring. The quality factors affecting the quality of the old epoxy flooring after the heavy construction mainly focus on whether the concrete layer still has enough use value. If the performance of the concrete layer has declined to the strength requirements of the construction of new epoxy flooring, it needs to be rebuilt. The epoxy floor paint is re-applied to the concrete layer. We have already introduced a lot of problems about the construction of epoxy floor paint in parking lot, basically based on the brand-new parking lot of the new building. But in the parking lot floor construction project, the renovation and reconstruction of the old epoxy floor actually account for a large proportion of the total project, so here we introduce. Introduce the main differences between the two. 与新停车场的地面情况相比较，旧停车场环氧地坪情况会更为复杂，如何对复杂环境进行专业的处理，对于后面环氧地坪漆的施工有着重要的影响，我们需要详细分析各种原因再进行相应的施工操作，下面用对比的方式进行。

Compared with the ground condition of the new parking lot, the ground condition of the old parking lot will be more complex. How to deal with the complex environment professionally has an important impact on the construction of the epoxy floor paint behind. We need to analyze various reasons in detail and then carry out the corresponding construction operation. The following is done in a comparative way.

一、新地面的停车场环氧地坪标准化施工

I. Standardized Construction of Epoxy Floor in Parking Lots with New Ground

1、检测地下渗水情况对于地面的影响，如果防水效果不足，则需要先建设专业的防水层。

1. Detecting the influence of underground water seepage on the ground, if the waterproofing effect is insufficient, we need to build a professional waterproofing layer first.

2、砼层养护，砼层施工完成之后，需要经过28天养护，使其强度达到最高状态。

2. Maintenance of concrete layer. After completion of construction of concrete layer, it needs 28 days of maintenance to make its strength reach the highest level.

3、专业环氧封闭底漆施工，在地下停车场地坪施工中，封闭底漆效果显著，不可省略。

3. Professional epoxy sealing primer construction, in underground parking lot floor construction, sealing primer effect is remarkable, can not be omitted.

4、砂浆中涂与腻子中涂施工，根据需求施工多次砂浆中涂可以提升地坪强度。

4. The strength of the floor can be improved by applying the middle coating of mortar and putty for many times according to the requirement.

5、自流平面漆施工，选择自流平材料可以进一步提升地坪的耐磨性与抗酸碱性能。

5. In the construction of self-leveling surface paint, the choice of self-leveling material can further improve the wear resistance and acid-alkali resistance of the floor.

二、老旧停车场环氧地坪翻新施工方法

2. Renovation Construction Method of Epoxy Floor in Old Parking Lots

旧环氧地坪翻新的前提是漆面磨损严重，但基底砼层未出现损坏或者局部损坏面积不大，可以通过局部修补之后进行面漆施工来延长整体地坪的使用寿命。

The premise of renovation of old epoxy flooring is that the paint surface is worn seriously, but the concrete layer of the base has not been damaged or the area of partial damage is not large. The service life of the whole flooring can be prolonged by painting construction after partial repair.

1、局部损坏地面修补，对于破损裸露的地面，需要先清洁干净之后，视损坏情况，采用砂浆中涂或腻子中涂进行修补后打磨平整。

1. Partially damaged ground repair. For damaged and exposed ground, it is necessary to clean it first, and then, depending on the damage situation, use mortar or putty to repair it and grind it flat.

2、整体打磨除污，修补好局部之后，需要采用专业的打磨设备，对老漆面进行全面的打磨，去除表面附着物、油污及已经松动剥落的漆层。

2. After overall polishing and removing dirt and repairing parts, professional polishing equipment is needed to completely polish the old paint surface to remove surface attachments, grease stains and loose and exfoliated paint layers.

3、自流平面漆施工，按照标准面漆施工之后再进行划线漆的标注即可。

3. Self-flowing surface paint construction, according to the standard finish construction, then mark the marking paint.

三、老旧停车场地坪重建施工方法

3. Construction method of old parking lot floor reconstruction

1、旧地坪的拆除：旧地坪拆除有抛磨法、火烧法、溶液浸泡法，采取适合现场施工的方法拆除旧地坪。

1. Removal of old floors: The old floors are demolished by polishing, burning and solution immersion methods, and the old floors are demolished by methods suitable for site construction.

2、砼层的修复：地坪拆除之后，如果砼层损坏严重的情况，需要把自流平水泥层打掉，然后重新施工水泥层及防水层，如果损坏不严重，则可以采取局部修补的方法恢复砼层功能。

2. Repair of concrete layer: If the concrete layer is damaged seriously after the floor is demolished, it is necessary to remove the self-leveling cement layer, and then rebuild the cement layer and waterproof layer. If the damage is not serious, local repair can be adopted to restore the function of the concrete layer.

3、新环氧地坪施工：根据以上第一点的停车场环氧地坪标准施工方法进行施工即可。

3. New epoxy floor construction: According to the standard construction method of parking lot epoxy floor at the first point above, construction can be carried out.

老旧停车场无锡环氧地坪漆施工的重点在于：老漆层的拆除、局部砼层损坏的修补、整体砼层作废的重建上有所不同，而环氧漆的施工上区别不大。但是为什么要把两者区别开来呢？

The key points of the construction of epoxy floor paint in old parking lot are: the removal of the old paint layer, the repair of partial concrete layer damage and the reconstruction of the whole concrete layer scrap are different, but the construction of epoxy paint is not very different. But why distinguish the two?
