Reasons for color difference in epoxy floor construction: precipitation of main agent of epoxy resin coating, insufficient mixing average; long contact time between pouring material and front joint in air; uneven thickness of coating; material breakage in construction; different batch topcoat. The precautions against chromatic aberration in epoxy floor construction are as follows: before construction, the main agent should be fully agitated and averaged; the contact distance between the main agent and the front joint should be prevented for a long time, and the whole operation line should be constructed together; the fixed tools should be used as far as possible and the construction purity of the builders should be enhanced; the coatings should be prepared at one time to avoid material breakage; and the same batch of coatings should be used as far as possible.
Causes and preventive measures of blistering in epoxy floor construction: high humidity of water and air in open layer of structure, near water tank, bottom floor or other air; no water cut-off disposal or poor primer blockade. Preventive measures, first of all, to grind well in the air, otherwise it is likely that the adhesion is not good. Every layer should be polished after it is dried, otherwise it will show the above situation. Pay attention to the construction time, do not insert construction, in order to avoid affecting the quality. Material should be stirred well, and each layer should be dried before the next process, so as to avoid foaming and other problems. The construction environment and weather are too wet to stop work. Before construction, the water meter should be used to assist the discrimination; the water cut-off treatment should be done at the place where the water content and pressure are too high; and hydrophilic epoxy resin primer should be selected.
