The detection of water whiteness resistance of architectural coatings is to evaluate whether the coating will appear white precipitation when immersed in water or exposed to humid environment, so as to determine its water resistance and antifouling performance. If the water resistance of the coating is poor, it is easy to appear white precipitation in the humid environment, thus affecting the appearance and protection of the surface of the coating. Therefore, the detection of architectural paint water resistance is to ensure that the paint has good water resistance and antifouling, in order to ensure the construction quality and service life of the building.

The water whiteness resistance of architectural coatings is an indicator to evaluate whether white precipitation will occur when they are immersed in water or exposed to humid environments. The following are the test methods and steps for the water resistance of architectural coatings:

Sample preparation: evenly spread the coating on the test sample to ensure uniform coating thickness, and cut into the appropriate size of the sample after drying.

How to test the water resistance of architectural coating?

Water immersion treatment: The sample was completely immersed in water for 24 hours.

Observation and detection: Take out the sample and observe whether the coating surface appears white precipitation or white phenomenon.

Data processing: By observing the data obtained from the inspection, the water resistance of the paint is evaluated, and usually according to the relevant standards, the rating of the paint is determined to determine whether the paint meets the application requirements.

How to test the water resistance of architectural coating?

We remind you: different types of paint to water tolerance is different, therefore, in the actual detection, according to different paint types and application scenarios, different detection methods and standards should be used to evaluate the water resistance and antifouling performance of the paint.

In a word, the detection of water resistance of architectural coatings is an indispensable work in architectural engineering. Through reasonable testing methods and steps, we can evaluate the resistance of coatings in humid environments, select suitable paint types and brands, so as to ensure the construction quality and service life of buildings.
