Test method for performance of polymer cement – based waterproof coatings
Polymer cement-based waterproof coating is a kind of waterproof coating made of polymer as the main raw material, by adding cement, наповнювач, additives, тощо. It has good adhesion, водотривкість, temperature resistance, chemical corrosion resistance and other characteristics, can effectively prevent moisture penetration, protect the surface of the building from water, moisture and so on. Polymer cement based waterproof coating is widely used in buildings, underground engineering, water conservancy engineering and other fields, such as roof, wall, basement, pool, water tower and other places of waterproof coating, to improve the waterproof performance and service life of buildings.

Test method for performance of polymer cement – based waterproof coatings
In the detection of adhesion, водотривкість, chemical corrosion resistance and other special properties, it is necessary to pay attention to the control of the detection environment and the selection of detection time to ensure the accuracy and reliability of the test results. Attention should also be paid to the origin and quality of the specimen and paint samples used during the testing process to ensure the representativeness and reliability of the test results.
