The invention relates to a decorative process, in particular to a damp-proof technology for a door pocket in a wet area. The damp-proof technology comprises the following steps that 1, plates with thehigh quality are selected as door pocket base layer plates; 2, a door pocket base layer is made by cutting the plates according to the thickness and height of a door opening wall; 3, the surface of the door pocket base layer is subjected to anti-corrosion treatment; 4, the door pocket base layer is installed, the lower end of the door pocket base layer is lifted to the suspension height being 20-50 mm from the ground, a technical cushion is embedded in the suspension height, the ground is a completion surface after surface decoration materials are laid on an original floor; and 5, door pocketdecorative facings are installed. According to the damp-proof technology for the door pocket in the wet area, the door pocket base layer in the wet area is installed on the door opening wall in a suspended mode, the technical cushion is installed, a damp-proof cushion and an anti-corrosion cushion can effectively prevent the ground moisture from spreading upwards, and a moth-proof cushion can repel insects and ants to prevent the insects and the ants from biting the door pocket; anti-corrosion paint is painted on the inner face of the base layer, so that the wall is separated from the door pocket base layer, moisture is isolated to permeate into the door pocket from the wall and cause mildewing and spot of the door pocket, and attractiveness, sturdiness and durability of the door pocket are effectively ensured.
