The environmental conditions have a great influence on the quality of the epoxy floor painting project, which is mainly reflected in the following aspects: the coating itself has requirements for the environmental conditions of the coating, and only in the environment that meets the requirements can good results be achieved. The requirements of the epoxy floor paint coating materials commonly used at present are generally as follows: no matter sealed. Closed primer, mid-coat or topcoat, because the reaction of amine curing agent is generally less than 5 C, it is best to coat at ambient temperature above 10 C. If it is lower than this temperature, some improvement measures should be taken for the coatings, and special attention should be paid to the coatings. Summer type is recommended when the temperature is above 20 C. When the temperature is below 20 C, it is suggested that the use system type be adopted. During the pre-curing process, the surface temperature of the base material should be higher than 3 C, in order to prevent the condensation of water vapor on the surface of the base material and wet film, which will affect the auxiliary force and surface effect of the coating. The instrument for measuring the ambient temperature has a temperature measuring meter and measuring the When measuring, the instrument should be installed in the place where the heat, cold and average data are collected, but not in direct sunlight. 高湿度也对涂层外观有很大影响，特别要避免在低温高湿环境下施工。所以一般相对湿度小于85%时方能施工，此类涂料一般可同时调整固化剂来适应不同的施工条件。
High humidity also has a great impact on the appearance of the coating, especially to avoid construction in low temperature and high humidity environment. Therefore, the general relative humidity is less than 85% before construction, such coatings can generally adjust curing agent at the same time to adapt to different construction conditions.
When the surface temperature of the substrate can not meet the condition that the dew point of the coating environment is higher than 3 degrees, on the one hand, the surface of the substrate dew (with a layer of water film), resulting in surface defects. Especially topcoats (including solvent-based epoxy and solvent-free epoxy) are liable to cause paint diseases such as low gloss, fogging, whitening, sticking, oil point and low hardness, which greatly reduce the decorative effect of the surface and cause rework in serious cases.
In addition, epoxy floor painting requires clean and dust-free painting environment, and requires environmental sealing during maintenance, which also has a great impact on the quality of the project. This includes whether there is dust in the construction site, whether there will be rain in the construction site and so on.
