If the wardrobe is assembled, there is a gap between the cabinet and the wall, which is usually15 mm. This 15 mm gap comes from the thickness of the skirting line under the corner. If you want to close the gap above, the front, left and right of the cabinet should be padded with 3 mm, so that the whole cabinet can be tilted backwards until the back is closed. Seal the gap with styrofoam first, and then scrape off the excess styrofoam with wallpaper knife. You can stick beautiful sewing paper on the seams of the wall to prevent styrofoam from polluting the wall. Then glue the gap between the cabinet and the wall with neutral glass glue.
If the size difference is too big, blow foaming agent in the gap, cut it off after drying, let the wall master fill gypsum or putty, and finally apply latex paint, so that the color of the gap will be the same as that of the wall. Glue is the first choice for the treatment of cracks between walls and cabinets, and china white is better. It is not recommended to scrape putty, because the putty is hard after drying, and the cabinets and walls are deformed, and the putty will continue to appear cracks or even fall off. The elasticity and adhesion of sealant are better choices. This is the case with most customizations. Because the cabinet is a standard 90-degree right angle, the angle between the ground and the wall is not standard, that is, the wall is inclined.
