Interior wall water-resistant putty is a kind of building material used for interior wall decoration and repair. It is mainly composed of polymers, pigments, fillers and additives. The interior wall water-resistant putty has excellent waterproof performance and durability, which can effectively repair and smooth the cracks and unevenness of the interior wall surface, making the wall more smooth, beautiful and durable. The characteristics of inner wall water-resistant putty include easy construction, quick drying, strong adhesion, not easy to crack and crack, and good water resistance. It is widely used in the interior wall decoration and maintenance of residential, commercial and industrial buildings, and is a very practical interior decoration material.

Detection performance
Interior wall water-resistant putty is a kind of interior decoration material, and the following performance parameters need to be tested, which are very important for the production and use of interior wall water-resistant putty. The specific detection performance is as follows:

Key performance parameters and testing methods of interior wall water-resistant putty

The above are some common test methods. In fact, there may be other parameters and test methods for the performance test of interior wall water-resistant putty. At the same time, for some performance parameters, it is necessary to follow the relevant standards and specifications, such as ASTM (American Society for Testing and Materials) or ISO (International Organization for Standardization), etc., to ensure the accuracy and reliability of the test. In addition, different countries or regions may have different testing methods for the performance of interior wall water-resistant putty, and the specific testing methods should refer to local standards and regulations.

Detection method
Construction performance: Observe the performance of the inner wall water-resistant putty in the construction process, such as coating, uniformity, easy coating, etc., and evaluate the appearance and quality of the coating to detect the construction performance.

Drying time: Observe the drying time of the water-resistant putty coating on the inner wall, and judge whether the coating is dry by touching and scratching.

Water absorption rate: Measure the amount of water absorbed by the inner wall water-resistant putty sample in a certain time, and use the water absorption test method to test. After soaking the sample in water for a certain time, measure the weight change of the sample and calculate the water absorption rate.

Compressive strength: To measure the compressive strength of the inner wall water-resistant putty sample under certain conditions, the compression test method can be used to test. The sample is placed in a press, compressed under a certain pressure, and the compressive strength of the sample is measured.

Adhesion: Measuring the adhesion strength between the water-resistant putty coating of the inner wall and the base can be tested using the stripping test method. The coating is torn off under specific conditions and the strength required to tear off the coating is measured to evaluate the adhesion.

Bending strength: To measure the bending strength of the inner wall water-resistant putty sample under certain conditions, the bending test method can be used to test. The sample is placed in the bending test machine and bent under certain conditions to measure the bending strength of the sample.

Crack resistance: To measure the crack resistance of the inner wall water-resistant putty sample under certain conditions, the tensile test method can be used to test. The sample is placed in the tensile test machine, stretched under certain conditions, and the tensile strength of the sample is measured, so as to evaluate the crack resistance.

Environmental performance: To detect the content of harmful substances, volatile organic compounds and other environmental pollutants in the inner wall water-resistant putty, various chemical analysis methods can be used for testing, such as gas chromatography, liquid chromatography, etc.

Notes
There are a few other things to keep in mind when testing:

Sample preparation: Sample preparation should be carried out in accordance with relevant standards or methods to ensure that the preparation process and conditions of the sample meet the requirements.

Experimental conditions: When performing various performance tests, it is necessary to control the experimental conditions, such as temperature, humidity, pressure, etc. to ensure the repeatability and accuracy of the experiment.

Test accuracy: For some performance parameters, such as compressive strength, tensile strength, etc., the test accuracy will be affected by many factors, such as sample preparation, experimental conditions, test equipment, etc. It is necessary to pay attention to control these factors to improve the test accuracy.

Data analysis: After the completion of each test, statistics and analysis of the test data are needed to determine the performance characteristics of the interior wall water-resistant putty and evaluate its quality level.

In summary, the performance testing of interior wall water-resistant putty requires different test methods and standards, and for some complex tests, professional laboratories or technicians are required to conduct them. The above problems should be paid attention to when testing to ensure the accuracy and reliability of the test results.
