环氧地坪表面的涂膜，因涂装质量不良，或在使用过程在逐渐老化、脱落、开裂，或因长期磨损造成涂膜破坏，需要重新涂装时，必须将损坏涂层去除。去除环氧地坪表面质量不良涂膜可采取以下方案：

The coating on the surface of epoxy floor must be removed when it needs to be repainted because of poor coating quality, gradual aging, shedding, cracking, or long-term wear and tear. To remove the poor quality of epoxy floor surface, the following solutions can be adopted:

将失效涂膜除去，而保留功能尚好的涂层再进行环氧地坪涂装，这里需注意，重新涂装前必须弄枪原涂装涂料的配套体系，严格按照涂料配套进行。检查被保留涂膜确无缺陷后，去顶涂料品种。

Removal of the invalid coating film, and retain the good function of the coating and then epoxy floor coating, it should be noted here, before re-painting must be gun original coating system, strictly in accordance with the coating matching. After checking that the coating is not defective, remove the top coating varieties.

若底漆为环氧地坪涂料，可保留完好涂膜，上面需配套涂装的涂料选择范围则较宽，大多数涂料都可以直接加涂。

If the primer is epoxy floor coatings, can retain intact film, the above coating needs to be coated with a wide range of coatings, most coatings can be directly applied.

完全将表面的涂膜去除，直至露出基材本体。当涂过漆的表面出现了腐蚀、起皮、起泡、开裂、起鳞或全面破裂的现象时，应把损坏的涂膜完全除去，直到露出裸露基体表面再重新涂装。由于重新涂装涉及涂料配套问题，如果是单组分环氧地坪丙烯酸、氯化橡胶等挥发干燥涂料，则很容易出现咬底等问题，环氧地坪加涂时一定要选择合适的涂料。

The surface coating is removed until the substrate body is exposed. When corrosion, peeling, blistering, cracking, scaling or total cracking occur on the painted surface, the damaged film should be completely removed until the exposed substrate surface is re-coated. Because the re-coating involves coating matching problems, if it is a one-component epoxy floor acrylic acid, chlorinated rubber and other volatile dry coatings, it is easy to occur underbite and other issues, epoxy floor coating must be selected when the appropriate coating.
