Testing the drying time of architectural coatings (surface drying) is to assess 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 aesthetics and protection performance of the coating surface, so it is necessary to detect the drying time 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.

How to detect the drying time of architectural coatings (surface drying)?

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

Prepare the sample: apply the coating evenly on the sample plate to ensure the uniform thickness of the coating, and cut the sample into the appropriate size after drying.

Drying time test: Record the drying 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.

Subsequent construction test: According to the suggestions of the coating manufacturer, the state of the sample before and after surface drying is observed to evaluate the subsequent 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 assessed, and the rating of the coating is determined, usually according to the relevant criteria, to determine whether the coating meets the application requirements.

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

In short, the detection of drying time of architectural coatings is a difficult or lacking work in construction engineering. Through reasonable detection methods and steps, you can evaluate the drying speed and 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.
