Better heated, so it absorbs more deeply and dries faster. Applying linseed oil can be an ordinary brush.
2. Ruberoid is placed under the sills, or, preferably, a rubimaster in two three layers. If the door is external, then to prevent decay of wood and fungus - a wooden door frame is beaten by a ruberoid around the perimeter.

Assembling wooden boxes for doors

1. The height of the lateral vertical posts on the folded ledges should be equal to the height of the door. The standard height of the door leaf is 200 mm. Add 2 - 3 mm gap between the bow and the base door leaf.
2. If you are planning a threshold, then add a further 3 mm tolerance from the bottom. Without shackle, the clearance is up to 1 cm, to prevent mashing in the event of precipitation.
3. The door box is assembled on the floor in a horizontal position. Fastening of corners is carried out by screws on a tree, and it is better than furniture confirmats, preliminary having drilled holes for their diameter. The tolerance for standard mounting of confirmations is 2 -3 mm less than the diameter of the screw.
4. In the reclining position, the door door itself is directly attached to the wooden door frame with the door hinges bolted to it.
5. On the door frame, a thin pencil marking is made with a pencil. The cells under them are hollowed out by a chisel, but the size and depth of the corresponding thickness of the hinge wing. The second fastening part of the hinge is screwed to the hollowed-out cell.

5. Collect the door frames on straight through spikes and glue. There is another way to fix the box, for this, long screws are screwed into pre-drilled holes with dowels.
6. Diagonal bars of wooden boxes provide proper strength and rigidity. Skylight _ is wetted in a damp way, that is, with cement or gypsum mortar, and it is better to blow out the foam along the entire perimeter.

Mounting the box in the doorway

1. Install the door frame in the designated opening. The lateral side is leveled, but the level. Prepared from wooden blocks mortgages - fit in size and installed on vertical side racks.
2. It is desirable to drill before installing mortises with a drill with a centered spout. By exposing the door frame to the level in the horizontal and vertical plane, you can begin fixing.
3. Self-tapping screws should not be pinched into holes. Having hardened the box, gradually tighten the screws checking the level in all parameters. Screws can be adjusted by the axes.
4. By adjusting the self-tapping screws, the door leaf is hung on the exposed door frame. The adjustment continues until the catches of the latches and lock bolts coincide.
5. Recently, fixation of the structure with the help of mounting foam is very popular. This is a good method, the foam mass fills all small cracks and has a low thermal conductivity.

After the foam has dried - the protruding mounds are removed with a mounting knife, and the cavities are sealed with putty. In the final, the clypeus is stuffed from the inside and outside.
