Collect door frame it is not difficult to do it yourself, if you correctly approach this process Often, door frames are sold in stores in disassembled form, and home master you have to assemble them yourself, carefully fitting them to the size of the doorway. So that the process does not take much time, it is recommended that you first familiarize yourself with the assembly technology, purchase the necessary tools, and then get to work. Every man should know how to assemble a door frame, since this skill is indispensable in the construction and repair, both in an apartment and in a private house.

The door frame consists of several bars different sizes, which need to be connected together, pre-fitting and under the dimensions of the opening. Two of them are longer - racks will be made of them, and two are shorter, a threshold and a crossbar will be made of them. The size of each element will depend on the height and width of the opening, as well as on the method of connecting the structure.

Ways of connecting bars:

With the help of spikes cut into the uprights and crossbars;
Washed down at an angle of 45˚;
Sawing at an angle of 90˚.

Before assembling the door frame, experts recommend that you familiarize yourself with the methods of connecting the bars

For home craftsmen with experience in carpentry, all of the above methods are suitable, and for beginners, they washed down at one of the angles. To cut the spikes, you need an electric jigsaw, for sawing at 45˚ - a miter box and a hacksaw, and to cut a beam at 90˚, you only need Miter saw or a hacksaw with fine teeth.

The spike connection of the door frame is strengthened with small carnations with an anti-corrosion coating or glued with wood glue.

To assemble the connection at any of the corners, a hole is first drilled, and then wood screws are screwed into it, the length of which is 50 - 60 mm.

Before making cuts at the ends of the bars, everything should be carefully measured and marked with a pencil, because the mistakes made cannot be corrected and you will have to buy new material.

Particular attention should be paid to the installation of hinges. Their locations must exactly match the location of the fittings on the door leaf.

How to cut a door frame at 45 degrees correctly

Basically, door frames with a rounded section are sawn at an angle of 45 degrees. If there is a threshold, then gashes will have to be done on all the details. In the absence of a threshold on the racks, the cutting is carried out only on one side, and on the crossbar - on both sides.

There are two ways to saw the door frame at an angle of 45 degrees, which you can choose at your discretion

Sawing methods at 45˚:

With the help of a chair. First, marks are made on the beam with a simple pencil, marker, or simply squeezed out with a sharp object. Then the beam is installed and fixed in the miter box. Carefully saw off the bar so that there are no chips.
Rotary table saw. A bar is installed on the frame at the desired angle, on which markings are applied. The saw quickly and easily saws off the excess part, leaving a smooth saw cut without cracks and chips.

It should be borne in mind that the distance between the box and the door itself (canvas) should be three millimeters.

When assembling the structure, the screws are screwed in at an angle. This step is necessary to securely fix the box.

Do-it-yourself quick installation of a door frame

Immediately after assembling the door frame, you can immediately install it. To do this, there is a certain algorithm of actions that must be carefully followed.

In order to quickly install the door frame with your own hands, you should prepare tools and materials for work in advance

Work procedure:

The doorway is cleaned of plaster residues and narrowed or expanded as necessary. The distance between the opening and the jamb should be no more than 2.5-3 centimeters.
The box is installed in the opening. For its reliable fixation, you will need a spacer made of wooden wedges. If there is no threshold, then a wooden plank is installed in its place.
The door frame is attached to the wall with anchor bolts or iron bars. The cavities between the opening and the jamb must be foamed mounting foam.
To prevent the box from deforming after the foam hardens, additional wooden wedges should be installed. They are pulled out in the process of cutting off excess foam.

In order not to stain the structural elements with construction foam, they should be pasted over with masking tape.

How to fix the door frame in the opening: detailed instructions

The stronger and more securely the box will be fixed in doorway, the longer the door will last without requiring repairs. There will be no particular difficulties if you follow all the tips and instructions. When installing interior door it should be fixed so firmly that it is possible, for example, to attach children's jumpers to it.

When fixing the door frame in the opening, you can additionally read the instructions

How to fix the door frame correctly:

After the door has been fixed with spacers, three holes must be drilled on each support;
Anchor bolts or metal rods are driven into the prepared holes, the ends of which are flattened;
If the installation is carried out in concrete wall, then special dowels are driven in;
All cavities are carefully filled with mounting foam with the expectation that it can double in volume;
In a narrow passage for fastening door frames, wide metal plates with holes are used, into which self-tapping screws are screwed or anchors are driven in.

Recommendations of the masters: how to put the door with the box

Not everyone will be able to install the door correctly the first time, especially if a person has never encountered this. First, he must study the sequence of work in detail. He may need a clear and detailed diagram structures and fixtures.

If you decide to install the door frame in the opening yourself, in this case it is better to do everything in stages

Stages of work:

Box assembly;
Fittings installation;
Installation and strengthening in the opening;
Hanging and adjusting the door leaf;
Trim trim.

If the door is made of MDF, then in no case should the slopes be plastered, but it is better to fill the space with extensions to match the color of the product.

Fittings can be inserted both before the complete assembly of the door frame, and after.

Spacers are best made in the form of wedges to make it easier to level the box.

Mounting foam is applied in stages several times. Until it completely hardens, you can not use the door.

How to competently assemble the door frame of an interior door (video)

Even a novice master will be able to install the door on his own without any problems, if he does not rush and uses the tools correctly. Don't despair when things don't go smoothly. You need to calm down, think it over carefully again or ask for advice from professionals. With the help of the recommendations given in the article, you can not only mount the doors yourself, but also control the work of hired builders who do not always perform it efficiently.

The door frame is wooden frame, most often from wooden beams and folds. Timber is a lumber made from solid or glued wood, often ten centimeters thick, used in construction, furniture and door production.

FROM German language the word "Falz" is translated as a groove, they call rectangular recesses on wooden blocks. In the manufacture of the box, with their own hands or at the factory, bolts and various metal linings are also used.

What is a door frame and what does it consist of

The door frame is the supporting part of any door and no assembly can do without it. It is mounted in the opening. When installed, loops and the canvas itself are hung on it. The work of the door itself in principle depends on the quality of the material from which the door frame was made and the professionalism of the installer. The box has horizontal and vertical slats. If desired, you can also install a threshold and dobor.

The choice of material used for manufacturing

Before proceeding with the manufacture of the door frame, it is necessary to choose the material from which it will be made. When choosing a material, it is necessary to take into account the weight of the door leaf, since it is the frame that will hold the entire door structure.

Often used:

Wood;
MDF or micro wood fiber;
Metal.

Often, it is wood that is used because it is more: durable, environmentally friendly and easy to cut a box with your own hands. It is worth considering the type of wood, since it is the breed that is responsible for strength. For the manufacture of the frame of interior doors, pine is mainly used. When choosing a material for entrance doors, often prefer oak.

Nowadays, there are already standard parts of the door frame, all that needs to be done with your own hands is to carry out the installation.

Removal of dimensions

In order to make a door frame with your own hands, you need to take measurements. This can be done in two ways:

Remove the size of the opening;
Take size down already installed door.

Consider the first option - measuring the opening. When using this method, it is necessary to measure each side of the frame, namely the height of the opening and its width in several places. It is also necessary to measure the diagonal of the opening, it serves as a control dimension in the manufacture of the box. There is another important measurement - this is the thickness of the box itself, it depends on the thickness of the walls themselves.

The second option is to measure the already installed door. First, measurements are taken of the sides and five centimeters are added to each measurement. Then, the threshold is measured, leaving room for allowances.

How to make a door frame

Making a box is considered a rather troublesome and time-consuming process, but in fact it is very easy and simple to do it yourself. When all dimensions are known, the cutting of the box parts begins.

The list of necessary tools for frame assembly:

Hammer;
Chisel;
Construction knife;
Roulette;
Pencil;
Screwdriver;
Square;
Plane;
Hacksaw.

First, two bars are prepared equal to the height of the opening and two bars equal to the width. All bars must be sanded from three ends, then they will front sides door frame. According to the width of the door frame, a gap is made into which the door leaf will be inserted. The gap must be made on the side that the door will open. If the door will open in both directions, then the gap must be made on both sides. Now, according to the same principle, we process transverse parts. After all the details are cut out, it is necessary to fit them to each other, and also make slots for installing loops.

Decorative part of the box

In addition to the fact that the box must be durable, it must also be decoratively beautiful.

The most commonly used option is painting. The color of the paint is selected under the door leaf or stain is used, it leaves the structure of the tree visible. After staining, the wood is varnished. Often, such an operation is done after the box is installed in the opening. decorative trim gives the door frame a finished look.

Mounting

Do-it-yourself installation is carried out in two stages. The first is assembly. Assembly must be carried out on a level, level surface such as the floor.

It is necessary to connect all the parts together and adjust to the size of the canvas. If everything matches, proceed with the installation.

Detailed video instruction in the video below:

Installation is carried out in the following order:

Measures are taken from the door and the places for the hinges are determined.
Not a large layer of wood is removed so that the canopies lie in line with the rack.
Mount all parts.
Install the box in the opening.
Adjusting the position of the slats and checking the installed box for level.
Fixing the box with wedges.
Fastening the box with bolts.
Install spacers between the box and the opening.
Filling the void from the box to the opening with mounting foam.
Removal of protruding wedges and dried foam.

If all the conditions for manufacturing and assembly are met, then this operation will not be difficult for you.

Conclusion

The door frame is the basis for the installation of any door leaf. Its manufacture does not take as much effort and time as it might seem at first. However, making a door frame with your own hands is not difficult. Enough to have necessary set tools and materials for its manufacture.

Final stage repair work in residential or commercial premises - installation of interior doors. High-quality assembly and installation of the box in the appropriate opening is the key to reliable locking of the canvas, right job main and auxiliary mechanisms.

The door frame is mounted in a wall opening, therefore it is a key part of the finished structure, to which the leaf is attached to the hinges. Let's figure out how to assemble a door frame with your own hands without involving third-party specialists, following a simple step-by-step instruction.

Choice of box sizes

Boxes for interior doors are made of reliable and practical materials - MDF, chipboard and wooden beams. The design of the box consists of several functional elements, so for its installation it is necessary to know the dimensions of all components.

The dimensions of the door frame of the interior door are determined by the thickness of the walls and the dimensions of the door leaf:

For brick walls 7.5 cm thick - a box 10.9 cm thick;
For walls made of wooden paving stones up to 10 cm thick - a box 12 cm thick.

The thickness of the door frame from foreign manufacturers may differ from the indicated dimensions, amounting to:

8 cm;
10 cm;
12.5 cm;
14.5 cm;
18.5 cm;
20.5 cm.

The correct ratio of the parameters of the thickness of the box and the wall opening eliminates the occurrence of violations in the future. With a wide wall and a narrow box, the finished structure must be expanded with wooden planks or boards installed in special grooves.

As standard, the frame for the opening is equipped with a special cutout, the depth of which is equal to ¼ of the thickness of the door leaf.

Modern models of interior doors can have different dimensions, but standard size- 80 cm. The width of the door frame is presented in two ranges:

Height - 2 meters, width - from 60 to 80 cm;
Height - 1.9 meters, width - from 55 to 90 cm.

Finished products are ordinary and profiled, and the width of standard elements can be from 1.5 to 4 cm.

Tools and materials for work

Installation of the door frame is carried out using the basic tools and necessary materials.

For work you will need:

Bars and wedges wooden.
Electric cutter.
Hacksaw equipped with a miter box.
Screwdriver.
Drill.
Self-tapping screws, nails with small caps.
Construction level.
Mounting foam.
Construction pencil.
Knife with a thin sharp blade.

For installation work the room must be dry and well ventilated.

The box is a frame-type structure, consisting of vertical guides - a loop and a feigned jamb. The hinge beam takes on the load of the installed door.

Preliminary installation work

Do-it-yourself installation of interior doors is carried out after finishing work on leveling wall surfaces, installing floor cladding and other finishing work.

Finished slopes should be checked vertically in several places. If a difference of up to 5 cm is detected, the slopes are leveled. Similarly, horizontal jumpers are checked. A technological gap of 15 mm should be observed between the floor surface and the door.

Proper assembly of the door frame determines the phased work:

Using a cutter, small recesses are made for hinged joints in the door leaf. The distance from the edge of the canvas to the edge of the loops (top and bottom) must be at least 18 cm.
The slopes are sawn at an angle equal to 45 degrees. The surfaces are carefully cleaned and trimmed, applied to the canvas and marks are made where the loops on the jamb will be placed. Using a cutter, recesses are made for the door hinges.
Finished hinges are inserted into the existing recesses in the canvas, holes are made for self-tapping connections with a drill. In this case, it is recommended to choose a drill whose diameter is equal to the diameter of the self-tapping screws. At the end, the hinges are fixed to the door leaf.

Installing the handle and lock

The next stage of work is fixing the handle and lock on the door, which is performed after installing the hinges.

The canvas is turned over in a horizontal direction and a recess is drilled at a distance of 85 to 118 cm on the side opposite to the loops. desired diameter to install a lock with a latching mechanism.
The lock is inserted into the recess, edging is done with a pencil. Using a cutter, another recess is made for attaching the front plate with a valve.
A valve is inserted into the canvas, while its body should be located at the level of the end of the door.
Next, marks are made on the door with a pencil under the recesses for the handles, which are drilled with a drill.
The lock latch is mounted in a recess from the end part and fixed with self-tapping screws.

Finally, handles are installed on self-tapping screws and decorative overlays using a simple hex wrench.

Complete assembly and installation of the box in the wall opening

At the final stage, the door frame is completely assembled and installed in the corresponding wall opening.

In the transverse box with a hacksaw, the ends are cut at a 45 degree angle. This will ensure a smooth and reliable docking of all elements. In this case, the width of the opening should exceed the dimensions of the door leaf by 6 mm.
The drill makes holes in the cuts of the angular type for the correct connection of the box. Many models of doors, which are equipped with platbands and slopes, are equipped with special cuts and fasteners. In this case, there is no need to drill additional holes.
Further, the slopes are carefully shortened in accordance with the dimensions of the finished door, observing the technological gaps between the floor and the lower part of the door of 15 mm.
All elements of the box are folded into a design that has the shape of the letter P on flat surface and securely connected with self-tapping screws.
In the grooves that are intended for mounting the hinge, through hole for fixing the assembled box to the wall surface. The box is fixed at the top of the opening with a long self-tapping screw.
The vertical position of the rack to which they are fixed door hinges, checked by the building level. Correction is carried out using wedges driven into the groove between the post and the slope.
A similar procedure is carried out with the second rack.
The horizontal location of the structure lintel should be parallel to the floor surface. Correction is performed with wedges.
After full check the position of the box, the design is securely fixed from below with self-tapping screws.
Next, it is recommended to hang the door to check the correctness of the work.

Step-by-step instructions for assembling and installing the box involves another important step - hanging the canvas.

Hanging the canvas is carried out using self-tapping screws, while the loops reliably hide the fixing elements. When properly hung, there should be no arbitrary opening / closing of the door.

After the box is securely fixed and the canvas is installed, the wooden wedges are removed from the technological gaps, and the existing gaps are filled with mounting foam, having previously covered all the installed fittings with masking tape.

Even a novice master, with the necessary tools, can perform his first installation of a door, whether it is an apartment, a house or a bathhouse. The main thing is to observe all stages of work and carefully check the correct fixation of all structural elements.

Installing the door frame of an interior door with your own hands is not as easy as it seems at first glance, so you need to approach this process with all responsibility. Before proceeding to work, it is worth carefully studying all theoretical aspects work, prepare the required materials and tools. In addition to learning the steps, you can watch a video containing detailed instructions for the performance of work. This will allow you to complete the installation without errors.

In order to mount an MDF box, of course, there cannot be a universal set of tools, but a list of the most necessary ones still exists. The first thing you need in almost any job is a marking pencil, a tape measure with a square and a knife. To prepare grooves for locks with hinges, well-known chisels cannot be dispensed with. In addition, you will need hammers, a level with a plumb line and a hacksaw. You need to buy screwdrivers and pliers.

Do not be afraid of power tools, since installation is hardly possible without a drill or screwdriver. In addition, a screwdriver is used not only for screwing in screws, but also instead of a drill, only with less power. A puncher will be needed for installation in the same way as a miter saw, with which the elements will be prepared.

The ideal option would be a universal trimming tool, which will allow not only to prepare elements such as additional strips, but also to trim the trim. A milling cutter will be of great help in the work, with which you can quickly make holes for locks, hinges or crossbars.

Opening preparation

If you still wondered how to assemble an interior door with your own hands, the first thing to start with is to check how even the wall is relative to the vertical. This is done by measuring the opening along the horizontal axis, and then along the vertical axis. It is best to take measurements in several places. The main goal is to create a gap of about 1.5 cm. It should be borne in mind that it must be present on all sides, and the difference in size between the opening and the door should be 2-3 cm.

Diagram of a door frame in a wall opening

There are times when the door leaf does not fit the opening a little in size. What to do in this case? For example, if the opening is larger, you can narrow it down a little by stuffing a plank of the required width over the entire area. If the difference is large enough, you can use brickwork, that is, to lay the extra space with bricks.

You can use another option: make a metal frame, followed by plasterboard wall cladding. If we talk about ideal, you must first make the necessary measurements, and then purchase the door and install it. This will avoid many of these problems.

box assembly process

Today, there are only three ways to assemble the door frame of an interior door with your own hands: with a tenon joint, fastening the bars at angles of 45 ° and 90 °. As for the first option, special spikes are made on adjacent bars. With their help, the connection takes place. The height of the spikes, as a rule, is similar to the thickness of the timber.

What is the 45° assembly technology? At the junction of the horizontal beam and the vertical one, a cut is made on both sides at the specified angle. When determining the length of the bars located vertically, it is necessary to take into account their thickness, the height of the opening itself and the size of the gaps. Their length must be the same.

As for the horizontal bars, you need to add up the thickness of all the beams vertically, the gaps, as well as the width of the door itself. Before cutting, it is necessary to check the measurements several times to see if the calculations were made correctly. Fastening can be done with nails or screws, and they must be screwed in at the same angle of 45 °.

If the connection occurs at a right angle, then the element, which is located horizontally, is installed on vertical beam. This method- one of the simplest, however, it involves sawing off the porch on vertical bars.

Once the bars are ready, you can assemble the door frame of the interior door with your own hands. All work must be done on as flat a surface as possible. When adjusting the bars, it is best to put something under them, for example, stools. To connect the structure, it is necessary to screw two screws into the corner joints. How to properly assemble the door frame, you can see on the presented videos.

How to install hinges?

The main thing is to decide on the operation of the door: where it will open. Before starting work, you will need to purchase the loops themselves and the entire essential tool. The side of the web for inserting loops should be chosen the one that is more massive and does not have any cracks and defects. Features of the insert depend on the type of loops. Installation of interior doors of a standard type is most often carried out on two hinges.

As a rule, they are quite enough. If we are talking about input structures, three loops can be installed here for greater reliability. For optimal load distribution, the third loop is installed slightly above the middle. You can determine the place where you want to install the hinges as follows: measure 20 cm from the bottom and top and mark up. Next, the loop is applied to the marked place on the end of the door and circled with a pencil, then with a knife.

Now, with the help of a hammer and a chisel, it is necessary to cut out a place for the loops about 3-5 mm deep, otherwise they will either hang out or stick out. In order to get the ideal depth, you need to cut the tree gradually, applying a loop periodically. The final stage is fitting loops and marking places for screwing screws. Next, holes are drilled. The hinges are fixed with screws.

How to mount the frame in the opening?

The block is mounted using self-tapping screws. It would, of course, be possible to fasten with anchors, but this is not advisable. Most often, in order to qualitatively fix the structure, 3 fasteners are enough. When assembling an MDF box with your own hands, the fastening elements must be masked with a hinge striker, as well as a lock. Next comes the installation in the opening itself. The rack is also fastened with self-tapping screws.

The next step is hanging the canvas itself, which needs to be well strengthened. When fixing the door leaf in a vertical way, it becomes fixed. After that, the lock rack is attached. On the canvas, you need to display the same gap between the crossbar and the uprights. It should not be more than 3 mm, otherwise the aesthetics of the door will be compromised.

If, on the contrary, it is made smaller than the indicated size, then over time, due to changes in humidity and wear of the hinges, it is likely that difficulties may arise with closing and opening. In buildings with brick walls, before installing the racks, you need to prepare mortgages for self-tapping screws. On each side, 4 spacers made of wood are mounted.

The gap formed during the work is removed with ordinary mounting foam, but you should be very careful not to stain the coating of the door itself with it. The foam hardens, as a rule, for 3 hours, however, the end of the process occurs in a day, when it becomes approximately 3 times larger in volume. When working with it, it is necessary to take into account the mentioned property, since if you “go too far”, then the elements of the block may suffer.

It is worth noting that the assembly of the box is a rather complicated process, which includes certain steps that require special attention. All work must be done step by step to avoid mistakes and disappointments. You can learn how to properly assemble the door frame of an interior door with your own hands from the video.

Installation, namely, the assembly and installation of an MDF door frame, is a rather painstaking process that must be thought out in advance and each stage must be approached responsibly. A person with minimal knowledge of installing interior doors can also install such a product. However, there is no room for error here. Otherwise, you will either have to redo everything or correct it, which can lead to the unsuitability of the assembled door structure in the hands of a beginner - you will have to re-install the door product. Therefore, the master must stock up on a sufficient amount of time and nerves. The whole process should proceed in stages.

At the very beginning of the work, before the assembly is carried out, it is necessary to determine the dimensions of the MDF product. It is necessary to make an accurate calculation, down to the millimeter, of the length of the loot racks and the upper bridge.
In order for the measurement to be the most accurate, after dismantling the old box, you need to remove the excess building materials– remnants of foam, plaster, etc. It is impossible to take measurements without flooring floor covering. Installation begins on the finished floor.
It is worth considering the distance from the wall to the box: the casing must fit entirely - when cut off, it can spoil the positive impression of the interior. When taking measurements, it is worth considering that there must be gaps between the door itself and the box. If the gap is large, the door will lose its attractiveness, and if it is not enough, the door simply will not close.
To measure the racks, you need to measure the height of the door. Racks should be equal to the height of the entire product. standard height equal to 2,000 mm. Leave a gap between the loot and the MDF sheet - 4 mm. From below, you need to add a gap of 1 cm so that the floor does not interfere with the use of the canvas.
As a result, the following indicators should come out: the height of the doors and racks will be equal to 2000 mm + 4 mm of the gap between the leaf and the loot + 10 mm of the gap from the floor = 2014 mm.

Assembling an MDF door frame

In order for the assembly of all components to be carried out correctly, first of all, you need to saw down the door frame to the size of the opening. Features of the saw cut - the top is at 45 degrees, the bottom remains flat - it will be installed on the floor. You can use a wood saw, but for smoother and more accurate work, it is better to file the corners with a circular saw.
Sides sawn at 45 degrees need to be pulled together. To assemble, you will need self-tapping screws for wood with a length of at least 55 mm and a drill with a drill. To prevent MDF from cracking, you first need to make holes of a slightly smaller diameter than the self-tapping screw, approximately 2-3 mm. Self-tapping screws are twisted from two outer sides of each corner - on top 2 and on the side in the center 1.
If, when trying on screwed parts, the height of the opening does not allow you to accurately place the structure, you can do this - knock down the plaster on top of the opening and file the beam located in the middle of the opening.
Before attaching door structure in the opening, you need to check the horizontal and vertical with the building level.
So that the installation does not subsequently disappoint the owners and, through negligence, does not violate the aesthetics of the box when fastened to the opening, you need to make holes for self-tapping screws in those places where the hinges will be attached and the latch will adjoin.

Insert hinges

Inserting the hinges begins with the choice of the side on which it will be decided to install the handle, and in which direction the door is planned to open. Both of these factors determine the location of the loops.
Two loops for an MDF product at the top and bottom will be enough.
When measuring and marking, you will need a goniometer. We apply a loop on the end side, circle with a pencil. Next, we make a recess with a chisel along the resulting contour to a depth equal to the thickness of the loop.
Ideally, the hinge markings should be set at a distance of 200 - 250 mm from the bottom edge of the door and 150 - 200 mm from the top edge.
After finishing the marking of the loops, we fasten them with self-tapping screws to the door.

Installation

The next step is to level the structure horizontally and vertically.

Use a drill to drill the required holes for the anchors. To securely fix, make three holes on the left and right, as an addition, you can also drill one more hole at the top and bottom.

The most crucial moment is fixing the box in the opening.

When trying to install, you may encounter a problem - if there is a thick layer of plaster in the opening, then the screws may not fall into the wooden part of the wall. To avoid this, you need to make a lining - wooden beam points so that the self-tapping screw is fixed, while it does not damage the plaster. A plank is carefully drilled into problem areas along the right size, on which the rack will subsequently be planted. After this manipulation, we install and fix the structure in the wall. Now it is important to set the vertical level. For this we take building level and adjust the first and second sides. Next you need to wedge the door frame: take ordinary wooden wedges and hammer under the top of the wall. Check again the level on both sides for slope.

Door leaf installation

After making sure that the assembled "frame" is firmly installed, you can begin to hang the canvas. In order not to keep it suspended during fastening, put a small wooden beam under it, it should be 1 cm. And thus this trick will help to carefully fix the canvas.
If the door is assembled and installed correctly and evenly, then the canvas in any position will stand as it should, as well as open and close freely.
After completing the installation of the entire assembly, you need to fix it - eliminate the gaps and foam it with mounting foam. At the same time, the gaps under the MDF door frame should be 4 mm, since the coating of this material absorbs moisture and can expand. In order for the door to close anyway when it dries out, you need to leave a gap between the canvas and the door frame of at least 4 mm. Liners need to be placed in them, because when foaming, the foam begins to expand and the gap may decrease.
Before this, the dusty surface must be moistened with water so that the PMP fits better. Then leave to dry for 30-45 minutes.

Installation at the final stage - installation of platbands. They are fixed with self-tapping screws or decorative nails. Assembly and installation completed.
