无锡环氧地坪【咬底】现象是指环氧地坪漆面漆将底漆涂膜软化、膨胀，在无锡环氧地坪表层形成皱纹的现象，一般在施工含有强溶剂环氧地坪漆材料时容易产生这种现象。环氧地坪漆出现【咬底】现象主要是两方面的问题：

Epoxy floor varnish [underbiting] phenomenon refers to the phenomenon that epoxy floor varnish softens and expands the primer film and forms wrinkles on the surface of the floor. Generally, this phenomenon is easy to occur in the construction of floor varnish materials containing strong solvents. There are two main problems in the appearance of epoxy floor paint. 

1、地坪漆材料不配套

1. Unmatched Floor Paint Material

一般来说环氧地坪漆材料厂家的产品都是配套生产，但不同地坪漆厂家配方不一样，如果混搭使用，很可能会出现原地坪漆发软的问题，而一旦底漆发软膨胀，就会出现【咬底】的弊病。所以要求施工同一厂家产品，这样可以减少风险。如果一定要分用两家材料，建议先小面积进行试验，无咬底现象才大面积使用。

Generally speaking, the products of epoxy floor paint material manufacturers are all matched production, but the formulations of different floor paint manufacturers are different, if mixed use, it is likely that the original floor paint will be soft, and once the primer softens and expands, there will be the disadvantage of underbiting. Therefore, the construction of the same manufacturer's products is required, which can reduce the risk. If two materials must be used separately, it is suggested that small areas should be tested before large areas can be used without underbiting.

2、涂层未干透就涂下一道漆

2. Paint a coat before it dries out thoroughly

环氧地坪漆是固化成膜的油漆涂料，要出现韧性、强度需要完全固化才行。而如果底漆还没有完全干就施工面漆，底漆和面漆会渗透在一起互相影响，从而导致【咬底】的问题出现。或者是面漆施工过厚，干燥时间过长，也会出现【咬底】的问题。

Epoxy floor paint is a film-forming paint, which needs to be completely cured in order to have toughness and strength. If the primer is not completely dry, the primer and the top coat will penetrate into each other, which will lead to the problem of underbiting. Or paint construction is too thick, drying time is too long, there will be a problem of undercutting.

环氧地坪漆出现【咬底】现象怎么办?

What about the phenomenon of underbiting of epoxy floor paint?

1、底漆和面漆应配套使用。

1. Primers and topcoats should be used together.

2、底涂层干透后再涂面漆;应在底漆还未完全干透之前罩面漆;在容易产生咬起的配套涂层场合，应先在底涂层上薄薄涂一层面漆，待销干后再进行面漆的厚涂施工。

2. Primer coatings should be coated after drying. Primer coatings should be covered before drying completely. In the case of matching coatings which are easy to bite, a thin layer of primer coatings should be applied first, and then a thick layer of primer coatings should be applied after the primer is dried.

3、如果出现严重咬底的现象，需将涂层全部铲除干净，待基层干燥后再选用同一品种的地坪漆材料进行涂刷。

3. If serious underbiting occurs, the coating should be completely eradicated, and the same kind of floor paint material should be selected for painting after the base is dried.
