Method for testing stain resistance and weather resistance of texture coating

The invention discloses a method for testing the stain resistance and weather resistance of texture coating. The method comprises the following steps that (1) putty powder is prepared; (2) four test plates are prepared, and putty powder applying and polishing are conducted; (3) each test plate is equally divided into an area A, an area B, an area C, an area D, an area E and an area F, the areas A,the areas B, the areas C and the areas D are coated with seal primer, the areas A and the areas B of two of the test plates are selected are coated with master standard white texture coating, the areas C, the areas D, the areas E and the areas F of two of the test plates are coated with to-be-tested white texture coating, the areas A and the areas B of the other two test plates are coated with master standard colored texture coating, the areas C, the areas D, the areas E and the areas F of the another two test plates are coated with to-be-tested colored texture coating, and then the areas B,the areas C and the areas
