The seams are overwhelmed first on the frame, and then around the door of the hatch. To do this, they clean them around the perimeter, then glue the masking tape around the seam. Then fill the seam with a sealant of the color that has a grout. The remains of the composition are cleaned with a rubber spatula. After two days, the seam to the entire depth is cut through with a knife, the door is opened. At this installation is completed. In those hatches when there are special nodes that regulate the door, the gap there must be adjusted around the perimeter.
