Method for testing adhering strength of theme plastering

The invention provides a method for testing adhering strength of theme plastering. The method comprises the following steps of cleaning dust and debris on a substrate, wetting the substrate, and fixing a mesh sheet on the substrate; spraying a plastering material, and immediately plastering to form a 10mm-thick plastering flat surface after spraying is completed; enabling a 8mm galling device to horizontally draw a 3 to 4mm-deep groove; wetting a second plastering layer; spraying a decoration surface material, so as to prepare a to-be-tested surface; adhering a drawing head onto the to-be-tested surface by an epoxy adhesive, and curing for 48h; cutting out a 75mm-diameter circular groove around the drawing head, and enabling the depth to reach the just middle part of the second plastering layer; performing drawing test. The testing method provided by the invention can provide technical support for ensuring the project quality. 本发明提供种主题抹灰粘结强度的测试方法，包括如下步骤：清除基材灰尘和碎片，润湿基材，将网片固定到基材上；喷涂抹灰材料，喷涂完成后立刻抹成10mm厚抹灰平面；用8mm拉
