三、四层及以上涂装系统：

Three, four or more coating systems:

    1、选用材料及特点：和二及三层涂装系统相比，主要是中涂层采用平底刮板刮涂的工艺，先刮砂浆后刮腻子，视厚度要求确定刮涂道数，结合打磨而找平地面，这样对中涂层的材料各方面要求降低了。而面涂采用生产好的无溶剂环氧自流平面漆甲乙混合后直接镘涂，不用现场加填料，可以控制面涂用量在0.8-1.2KG/M2之间。

1. Selection of materials and characteristics: Compared with the two and three-layer coating system, the medium coating is mainly scraped by flat bottom scraper, scraping mortar first, then putty, depending on thickness requirements to determine the number of scraping routes, combined with grinding and leveling the ground, which reduces the requirements for all aspects of the medium coating material. The surface coating can be directly upset by mixing solvent-free epoxy self-flow planar paint A and B. Without filling on site, the amount of surface coating can be controlled between 0.8 and 1.2KG/M2.

    2、施工要点：施工工序较为繁多，施工工期长，人工费用高些。

2. Key points of construction: there are many construction procedures, long construction period and high labor costs.

    3、主要特点：这种工法和二层、三层涂装系统相比，材料费用低，所以该工法占主流。

3. Main features: Compared with the two-layer and three-layer coating systems, this method has the lowest material cost, so it is the mainstream.

    保定环氧自流平地坪漆的施工方法，在施工的时候一定要按照上面的步骤进行，咬住各个步骤上的施工特点和施工要点，不可大意，否则会影响地坪漆的施工质量。

The construction method of epoxy self-leveling floor paint must be carried out according to the above steps during the construction. The construction characteristics and key points of each step should not be carelessly bitten, otherwise the construction quality of floor paint will be affected.
