So that the door box is firmly held and does not lead to a loosening the door itself, you need to correctly and securely fix it in the doorway. To do this, use thick and long metal pins or nails of the same size. With concrete walls, into which it is difficult to drive anything, the mount should be carried out on dowels. In the concrete wall, the holes of the same size and diameter are pre -drilled as the nails or pins, and wooden plugs are inserted into these holes. Now many people buy high -quality metal doors inexpensively.
With the help of wooden wedges and using the construction level and the plumb line, the door block is aligned in the opening and only after that is fixed. The cracks formed between the wall and the door block are filled with construction foam, which is very convenient to use, since it quickly fills all the voids and cracks, and after drying all the excess can be easily removed with a knife. Inside the door block, you must first install vertical and horizontal spacers, and then pour foam. You need to install spacers so that the drying and hardening foam does not deform the door box. After installing the door, you can also mount a door skirting board, the fasteners of which are carried out according to the pre -made holes. The holes are first drilled with a small drill, then a larger drill. The skirting board must be fixed and trimmed strictly at an angle of 90 degrees, for which a building corner is used.
