Testing the drying time of architectural coatings (surface drying) is to assess the drying speed and degree of paint in the process of construction, 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 aesthetic and protective performance of the coating surface, so the drying time detection is needed to ensure the quality of construction. At the same time, the subsequent coating construction before the coating surface is completely dried will also affect the adhesion and durability of the coating.

Detection method
The drying time (surface drying) of architectural coatings is an index to evaluate its drying speed and degree in the process of construction. The following are the testing methods and steps for the drying time of architectural coatings:

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

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, and drying time.

Follow-up construction test: According to the suggestions 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 tests, the drying time of the coatings is assessed, and the rating of the coatings is determined, usually according to relevant criteria, to determine whether the coatings meet the application requirements.

We remind you: different types of paint in the drying time performance is different, therefore, in the actual detection, should be based on different paint types and application scenarios, the use of different detection methods and standards, in order to evaluate the drying speed and degree of paint in the construction process.

In a word, the detection of drying time of architectural coatings is an indispensable work in architectural engineering. Through reasonable detection methods and steps, you can evaluate the drying speed and drying degree of paint in the construction process, choose the appropriate type and brand of paint, so as to ensure the construction quality and service life of the building.
