膩子刮痕是指環氧地坪漆涂料涂層表面刮過膩子的部分產生殘痕或失光現象，而環氧地坪漆的工序主要劃分包括底漆層、砂漿層、膩子層和面漆層，因為環氧地坪漆膩子層是最接近面漆的一層，而面漆層又非常的薄，這就產生了如果膩子層在批刮施工時留下了痕跡，輥涂面漆后，從而使整個環氧地坪工程都將存在刮痕。讓施工和打磨都比較費力。因為耐水膩子較結實， 產品膠性大，攪拌和批刮時要比非耐水膩子困難。耐水膩子的強度也要比非耐水膩子高，打磨時也會比較費力。如果環氧地坪漆工程出現大量刮痕，將會嚴重影響環氧地坪的表光效果。并且會導致環氧地坪的摩擦系數提升，將導致無法達到前期商定的要求。因此如何避免出現膩子層刮痕是非常有必要的。

Putty scratch refers to the phenomenon that the part of the epoxy floor paint surface scratched over the putty produces residual marks or loss of gloss, while the process of epoxy floor paint mainly includes primer layer, mortar layer, putty layer and topcoat layer, because the putty layer of epoxy floor paint is the closest to topcoat layer, and the topcoat layer is very thin, which results in this phenomenon. If the putty layer leaves traces during batch scraping construction, the scratches will exist in the whole epoxy flooring project after roller coating. Make construction and grinding more laborious. Because the water-resistant putty is stronger and the product is more gelatinous, it is more difficult to mix and scrape than the non-water-resistant putty. The strength of water-resistant putty is also higher than that of non-water-resistant putty, and it will be more laborious when polishing. If there are a lot of scratches in the epoxy floor paint project, it will seriously affect the gloss effect of the epoxy floor paint. The friction coefficient of epoxy flooring will be increased, which will lead to the failure to meet the agreed requirements. Therefore, how to avoid the appearance of putty scratches is very necessary. 環氧環氧地坪漆膩子刮痕產生的原因：

Causes of Scratch on Putty of Epoxy Floor Paint:

1、刮涂膩子部位未涂封閉底漆，膩子層的吸油量大;

1. Scraping putty parts without sealing primer, putty layer has a large oil absorption;

2、所使用膩子的收縮性大，固化后容易變形，產生膩子殘痕。

2. The putty used has large shrinkage and is easy to deform after curing, resulting in putty residue.

3、涂刮膩子層部分打磨不足，出現凹凸，不平整現象，沒有經過處理直接施工環氧面漆;

3. Lack of polishing, concave and convex, uneven phenomena appeared in the coated putty layer, and epoxy topcoat was directly constructed without treatment.

有效避免環氧環氧地坪漆膩子刮痕的方法：

Effective methods to avoid scratches on putty of epoxy floor paint:

1、由于收縮性大，造成的膩子殘痕，應選擇使用配套的膩子進行刮涂;

1. Because of the large shrinkage, the putty residue should be scraped with matching putty.

2、避免產生膩子殘痕，建議對涂刮的膩子層充分打磨，光亮、平滑后，再進行環氧面漆施工;

2. To avoid putty residue, it is suggested that the coated putty layer should be polished sufficiently, and then epoxy finish should be applied after it is bright and smooth.

3、由于底漆封閉層，封閉性不強，膩子層吸油量過大，我們應該在刮涂膩子層前刷涂封閉底漆，做好基層處理。

3. Because the sealing layer of the primer is not strong and the oil absorption of the putty layer is too large, we should brush the sealing primer before scraping the putty layer, and do a good job of grass-roots treatment.
