1、 Temperature

1. RequirementThe curing temperature of epoxy floor paint is 15-25 ℃, and the construction environment temperature for floor paint is required to be between 10-35 ℃.

2. The Influence of Temperature on Floor Paint Construction

(1) Low temperatureWhen the temperature is below 5 ℃, the curing of floor paint will slow down or even stop, resulting in slow surface drying or incomplete curing of the coating film. The curing process of floor paint coating is too long, and the floor is easily damaged by foreign objects such as dust and mosquitoes. At the same time, the strength, hardness, wear resistance and other properties of the coating will be reduced.

(2) The temperature is too highWhen the construction environment temperature is too high, the curing time of epoxy floor paint will be significantly shortened. If the construction speed cannot keep up with the curing rate of the paint, it will cause the paint to be cured and scrapped, and even lead to paint explosion. At the same time, construction operations in high temperature environments can also have adverse effects on workers' health. Therefore, when the temperature is above 35 ℃, it is advisable to avoid the construction of floor paint as much as possible

2、 Relative humidity

1. RequirementThe construction of floor paint requires a relative humidity of less than 75% in the construction environment.

2. Relative humidityRelative humidity is usually expressed as RH, which represents the moisture content in the air at a certain temperature. When the relative humidity reaches 100%, condensation begins.

3. The Influence of Relative Humidity on Floor Paint Construction

　　When construction is carried out in an environment with a relative humidity above 85%, the coating of floor paint is prone to problems such as whitening, cracking, and peeling. Therefore, floor paint should be applied in an environment with a relative humidity below 75%.

　　It should be emphasized that it is not only the construction process that requires relative humidity of the environment, but also that the relative humidity of the air during construction and the curing period of the floor paint coating must be below 75%. Therefore, floor paint construction should not only consider the relative humidity on the day of construction, but also pay attention to the weather conditions in the next few days.

3、 Dew point temperature

1. RequirementWhen applying floor paint, it is required that the temperature of the construction base surface be 3 ℃ higher than the dew point temperature, otherwise it cannot be applied.

　　Details: The base surface of the floor paint must be 3 ℃ higher than the dew point temperature. Detailed explanation of the reason

2. Dew point temperatureDew point is the temperature at which moisture in the air condenses into dew drops, and it is a temperature indicator. Keeping the moisture content in the air constant and lowering the temperature will increase the relative humidity. When the relative humidity reaches 100%, the moisture in the air will condense, and the temperature at this point is the dew point temperature.

3. The impact of condensationWhen the surface temperature is lower than the dew point temperature, water vapor in the air will condense and condense when encountering objects with lower temperatures, producing water droplets on the surface. The water condensed on the ground will damage the curing agent components in the epoxy floor paint, causing problems such as whitening, loss of gloss, and sticking back.

4、 Other

　　In addition to temperature, relative humidity, and dew point temperature, the construction of floor paint should also pay attention to issues such as site enclosure, lighting, and electricity.

1. Closed siteCheck whether the doors and windows on the construction site are intact and can be sealed to prevent external dust, mosquitoes, etc. from damaging the floor paint coating and affecting the aesthetics of the floor.

2. Avoid cross assignmentsThe construction of floor paint should avoid cross operation and should be staggered with wall construction, water and electricity layout and other operations as much as possible to prevent debris from falling off and sticking to the floor paint, affecting the floor effect.

3. Lighting and electrical equipmentWhen the construction period is tight or the epoxy self leveling needs to be completed in one go, the floor paint needs to be applied overnight, and complete lighting and power facilities are required at this time.
