The coating quality of epoxy floor paint depends on three parts of the coating and seven points of the coating depend on the construction. If the strict construction technology is not used, the excellent effect will not be obtained. Therefore, the construction of epoxy floor paint is very important. The construction temperature of epoxy flooring should be controlled in the range of 10-35 C, and special kinds of epoxy flooring coatings should be used beyond this range. In the process of coating and curing (before surface drying), the surface temperature of the base material should be higher than 3 C of dew point, so as to prevent the water vapor condensation on the base material and wet film surface from affecting the adhesion of the coating. And surface effects.
Summer construction requirements
It is suitable to construct in the morning or evening in summer. Temperature should be measured during construction. When the temperature exceeds 35 C, construction should be avoided in order to improve the health of construction personnel and the quality of coating film. In wet and rainy days, it is necessary to measure relative humidity and dew point temperature, inspect the quality of the dried film at any time, and repair it in time when cracks, orange peel and peeling occur. For two-component coatings, slow volatile solvents should be used as far as possible in the preparation of diluents and curing agents. When mixing A and B components, the principle of a small amount and many times of diligent mixing should be adopted to prevent the phenomenon of excessive heat release in the curing of coatings from causing paint scrap. When the temperature is too high, two-component coatings, especially insoluble two-component coatings, are prone to explosion. That is to say, the reaction of coatings is too fast and a large amount of heat release shortens the service life of coatings. In high temperature construction, although the drying rate of the coating will be faster, the next coating should be carried out according to a certain painting interval even if the measurement is dry.
(2) winter construction requirements
When there is fog or the surface of the coating is covered with water vapor and frost and snow, it is not suitable for outdoor construction. During construction, the surface temperature of the coating should be higher than dew point 3 C, and the temperature should not be lower than the minimum temperature prescribed by the drying of the coating. When construction is under 10 (?) C, it is generally necessary to work from 10 a.m. to 3 p.m. to make full use of the time when the temperature is high, organize the construction force and complete the work as soon as possible. As far as possible, select special winter curing coatings. If the paint is too thick and difficult to be coated, solvents with a faster volatilization rate of less than 5% can be added, such as acetone, ethyl acetate, butyl acetate, etc. Coatings can be stored in a warm environment or heated by hot water or steam (which may result in a decline in the quality of the paint). When a thermothermal coating is applied, the temperature shall not exceed 38 C unless a special coating heating device is used. When the flash point of the coating is below 38 C, the heating temperature shall not exceed its flash point. Pay attention to opening the lid of the packaging barrel, avoid water vapor entering, prohibit direct heating with open fire or electric fire, and pay attention to safety when heating. Compared with the conventional coating requirements, the number of coating paths can be increased and the coating interval can be prolonged on the premise of guaranteeing the film thickness. After testing the film dry, the next coat is applied.
