Testing the drying time of architectural paint (table dry) is to evaluate the drying speed and degree of paint in the construction process, so as to determine its scope of application and construction quality. If the drying time of the coating is too long or too short, it will affect the beauty and protection performance of the coating surface, so it is necessary to test the drying time to ensure the construction quality. At the same time, the subsequent coating construction before the coating surface is not completely dry will also affect the adhesion and durability of the coating.

How to test the drying time of architectural paint (table dry)?

Method of detection
The drying time (table dry) of architectural paint is an index to evaluate its drying speed and drying degree in the construction process. The following are the testing methods and steps for the drying time of architectural coatings:

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

Drying time test: record the drying condition of the coating within the specified time after construction, observe the state of the sample surface, such as surface dry, hard dry, etc., and drying time.

Follow-up construction test: according to the recommendation of the coating manufacturer, observe the state of the sample before and after surface drying to evaluate the follow-up construction performance and the adhesion and durability of the coating during the construction process.

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

We remind you: different types of paint in the performance of drying time 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 drying speed and drying degree of paint in the construction process.

In short, the detection of drying time of architectural coating is an indispensable work in construction engineering. Through reasonable detection methods and steps, the drying speed and degree of paint in the construction process can be evaluated, and the suitable type and brand of paint can be selected, so as to ensure the construction quality and service life of the building.
