1. Measurement of temperature and humidity, determination of dew point

The instruments for monitoring the temperature and humidity of the environment include temperature and humidity measurement tables, operating dry hygrometers for measuring dry and wet soaking temperatures, and continuous electronic temperature and humidity recorders. When measuring, the meter should be installed on the site where the hot, cold and average area data are collected, but it should not be installed in direct sunlight, wind, heat radiation, heating or ventilation ducts or other locations that affect the average count.

In the past, wet-bulb thermometers were used to measure the temperature and relative humidity. They consist of two identical mercury (or ethanol) thermometers. One of them consists of two layers of gauze (or cotton). The lower end of the gauze is immersed in a water-filled vial. The thermometer The reading is wet bulb temperature and the other thermometer reads dry bulb temperature. According to the dry and wet bulb temperature difference, the relative humidity in the air is detected in a dedicated meter.

At present, there are measuring tables for measuring ambient temperature and relative humidity on the market, which can directly measure the temperature and humidity, and check the dew point temperature by comparing the temperature and relative humidity cross points in Table 5-15. The coated surface temperature should be higher than the dew point of 3 °C before coating.

In the absence of the above conditions, a very clear, thin layer of water may be applied to the cleaned surface with a damp cloth and evaporated in 15 minutes to be considered as meeting the dew point requirement.

2. Other requirements and inspection items

Because the floor construction requires a clean and closed coating environment, the negligence of any one detail may cause defects or rework and cause losses. Therefore, the following aspects need to be inspected before entering the construction site:

①Whether the doors and windows are intact, whether the construction site can be closed, and whether the roof, water pipes, etc. are leaky;

②Avoid cross-operation, moderate ventilation during construction, but should prevent sand, dust and other pollution around;

③Whether the facilities such as lighting and electric power are complete, and if they are to be provided by themselves, they should be planned and prepared;

④Note the weather forecast, whether the weather conditions during the proposed construction are suitable.
