The casings are made from different materials.- wood, plastic, MDF. They can be laminated, veneered or varnished. But they have one function - to hide the gap between the wall and the door frame. The door frames are installed at the final stage of the renovation, when not only the door frame is installed, but the walls are also wallpapered, tiled or painted.

Than to strengthen the platbands
The most common method of fasteningtrims are finishing nails. Their optimal length is 3-4 cm, since they should enter the frame by 1.5-2 cm. It is better to give preference to thin nails with a miniature flat head. If there are none, then the head can be removed using side cutters. This procedure is done when the nail is driven in three quarters. This installation method is simple and reliable, and the trims can be easily removed and installed if necessary.
Installation diagram of a metal door for a flatthe casing is flush with the wall. Glue in tubes (liquid nails) can be used for fastening, provided that the surfaces are absolutely flat. It is very easy to work with: cover the back of the casing with a thin strip and press it firmly against the wall. After holding for a few seconds, everything is ready. The main thing is that there is not too much glue, as it can get on the wall and will be difficult to remove. Liquid nails, unlike regular nails, do not leave marks on the front side, allow you to do the work quickly, but the reliability of such fastening is not the highest. Their disadvantage is also the difficulty of dismantling the structural elements. In addition, if you plan to install wooden casings, it is not recommended to use glue. They can be fastened with self-tapping screws 2-3 cm long and 5-6 mm in diameter. When working with wood, the following must be taken into account: to prevent splits from appearing on the material after fixing, you need to drill holes with a slightly smaller diameter than the self-tapping screw in the places where the fasteners will be. To make the cap less noticeable, it needs to be “drowned”. To do this, drill a small recess on the front side. It is quite easy to install using special fasteners - “beaks”. With this type of installation, the door trims are wedged into the grooves made in the frame. As a result, the entire “edging” of the door looks aesthetically pleasing. This method of fastening is undesirable only for MDF trims, since the “beak” may delaminate in the event of dismantling. Return to contents</a>
Variants of installation of platbands
Scheme of finishing slopes with MDF trims. To install trims, you will need the following tools:
- fasteners (nails, glue, screws);
- protractor or stool;
- a hacksaw on wood;
- roulette.
There are several options for installing door frames:
- butt joint;
- using a decorative insert;
- cut at an angle of 45 °.
If you need to frame an interior door, thenThe butt-to-butt arrangement is used quite rarely. It is mainly used in cases where there is a need to use telescopic trims. They have projections that allow them to be attached to the extension or door frame. As a rule, it is advisable to install them if the wall is thicker than the frame. Image 1, 2 A decorative insert - also known as a capital - is rather a door decor, although it is also considered a trim and is installed together with it. When using it, the trims are usually arranged "butt-to-butt" and not at an angle. A capital is used only in some styles. It can be standard and included with the door or custom-made for a specific interior. Image 3
Doorway parameters.The most popular method for framing a door is to install the door trims at an angle of 45°. The first thing you need to do when installing is to cut the required length from the material purchased in the store. To do this, you can attach the strip to the door frame and make a mark. Keep in mind that the height should not be equal to the inner part of the frame; you also need to add the width of the trim to this value. Then place the strip on a flat surface, use a square to determine the right angle, and cut off the rest. If you are working with a trim covered with PVC film, then turn it over so that there are no chips when cutting. If you are installing the strips “butt to butt”, this is where the work with the vertical ones ends. If not, then the trim is then attached to the door frame, aligned, and a mark is made for the inner angle. Next, starting from this, use a protractor or miter box to set off the 45°C angle and cut it off. Image 4 After this, the first side trim is ready. The same actions should be taken with the second one. It is highly undesirable to "take measurements" from the first one - there may be errors in height, and the material will be spoiled. After both side strips are ready, experts do not advise moving on to fitting the top one, it is better to first fix the vertical ones. Return to the table of contents</a>
Installation of platbands
The door frames are applied to the door one by one.the box, and nails are driven into them. As a rule, they are located at a distance of 50 cm from each other, that is, one at the bottom and one at the top, and the other two at an equal distance. There is another option. Nails are driven directly into the box, while about 5 mm remains on the surface, which is necessary for “putting” the casing on them. Then the heads are removed using side cutters or nippers. It is not recommended to hit directly on the strip during installation. It is better to use a wooden block wrapped in fabric. After the vertical casings are installed, the upper one is applied to them, and the cut point is marked (on both sides). Then the excess is removed, and the upper strip is installed in the same way as the side ones. If the marking of the upper casing is carried out according to the vertical principle, then minor errors are possible, and a gap of even a millimeter will spoil the entire appearance of the door. If cracks appear, it is recommended to mask them with acrylic sealant or wax corrector of the desired shade. Since it is quite easy to install door frames, any novice craftsman can do the job, that is, finish installing the door. But you will have to be patient. Otherwise, you can get a lot of spoiled material. If you are going to improve interior doors yourself for the first time, then first choose the largest opening, since in case of a mistake, these strips can be used for others, those that are smaller.
