Waterproof glue between aluminum alloy aluminum sliding door frame and wall must be carried out after the wall is completely dry. 

At the same time, before playing waterproof glue, the base should be treated with ash removal and gravel removal. If the wall is not completely dry and dust is not cleaned, the water vapor released by the wall will make the sealing effect of waterproof glue fail, and eventually lead to water leakage and seepage in the whole door.
