First you need to decipher the abbreviation. MDF in English means medium density fiberboard. The material is made from dried wood fibers treated with synthetic binders. They are formed into a carpet shape and then hot pressed and sanded. Density is 700-870 kg/m³.
The material has the following advantages:
MDF is considered a replacement natural massif tree. At first glance, it is almost impossible to distinguish products made from wood chips from wood, provided that the material is made of high quality.
The disadvantages include the following properties:
Price interior design from MDF depends on the type of canvas. From of this material They mainly produce panel and panel products. The former are a solid canvas with or without internal filling, while the latter have decorative inserts. The latter are a lighter and more economical design due to panels that are lightweight.
Panel doors consist of three parts:
The base is made of beams. Mostly pine materials are used for production. The beams are located around the perimeter of the structure, and in some cases additional inserts are made for mounting fittings. Greater value has door filling. The quality of sound and heat insulation of the structure depends on this. Cardboard or hardboard is mainly used.
The main reasons for choosing such materials are to maintain the lightness of the doors, reduce sound transmission and thermal conductivity. In expensive products, the interior is made of MDF, which increases the weight of the structure and its cost. The cladding is made of wood chips.
Paneled doors consist of the following parts:
The base is made of solid wood. Depending on the number of panels, 1 or more horizontal jumpers are made. To give the structure a uniform look, it is often covered with MDF boards. Inserts are made of wood-based material or glass. MDF is convenient because it can be easily milled. This allows you to create panels of any shape and size.
Decorative coating is important parameter when selecting slabs for the design and decoration of a room. There are these types of finishes:
When purchasing, you need to pay attention to the following parameters:
To install an MDF interior door with your own hands, you will need the following materials and tools:
Installation door leaf is performed in the following sequence:
Installing a door yourself is not difficult if you have basic locksmith skills.
The quality of the proposed interior doors, which can be purchased in most construction stores, may not always satisfy customers. They can be beautiful and attractive, but the strength and durability of these products leaves much to be desired. Therefore, many home craftsmen have no choice but to make interior doors with their own hands. Moreover, there are no great difficulties in this if you select the material and follow a certain plan.
Before starting work on self-production interior door requires preparation of material. In most cases, wood is used for this purpose. The frame of the door leaf, as well as the door frame, is made from it. In addition to wood, the following can be used:
Polystyrene foam and cardboard honeycomb are used as a filler for the door leaf; it is not made of solid wood. These materials are lightweight, which is important for subsequent use. In addition, polystyrene foam can reduce noise levels by making the fabric more sound-absorbing.
The use of glass for the manufacture of interior doors is primarily due to the aesthetic side. Such inserts visually expand the room and also allow you to diversify the design of the room. Glass also has one more property. It passes perfectly daylight. Therefore, with glazed interior paintings the corridors of the apartment will be much lighter, even if the door is closed.
Fibreboard or its more advanced version MDF is used as sheathing material . In the construction of the canvas, these materials are responsible for decorative finishing future product. At the same time, MDF is the finishing element, but fiberboard will have to be further processed to give it an attractive appearance.
In addition to the listed materials, sheets of laminated chipboard can be used as cladding. Wide selection of colors that imitate natural wood, makes this type of finishing very popular. It should be noted that the use of laminated chipboard will give the doors more rigidity in the diagonals.
As fastening material You can use PVA glue or confirmats. To coat the finished canvas you will need varnish. If you need to add color, the problem is solved thanks to stains and tinted varnishes.
The next stage of preparation will be preparing the tools that will be needed to make an interior door. You need to have on hand:
With this set you can safely start making any carpentry product. You should also prepare a vacuum cleaner to quickly remove not only sawdust, but also dust, which should not end up on the surface of the product during paintwork.
When the preparation ends, it’s time for the main work. You will need to perform the following steps step by step:
In order for the work to proceed quickly and the product to turn out to be of high quality, it is worth preparing a drawing. Thanks to it, it is easy to mark and not make a mistake with the configuration of the future door.
The principle of assembling a paneled door 
The work should begin with measurement doorway. This operation will allow you to calculate the dimensions of the box and canvas, as well as determine the configuration of the future product. If the opening does not exceed 80 cm, then a single-leaf one should be made door block. With more large size you need to make two canvases to reduce the load on the loops and give a more attractive appearance to the entire product.
The resulting size must be reduced in height and width by 2 cm. This is required to create assembly seam, obtained between the box block and the opening slope. After installation, it is filled with polyurethane foam. Using the obtained dimensions, a drawing is drawn up according to which the interior door needs to be made.
Door leaf dimensions Such a manual should also contain the dimensions of the door leaf. To calculate them, you should subtract from the width and height of the opening the thickness of the box beam in the place where the quarter will be selected. From the resulting size it is necessary to subtract another 4 mm in width and from 4 to 12 mm in height. These values correspond to the gap that should remain for the free rebate of the door leaf. This defines all the data for the drawing.
It should be noted that the box beam does not have to cover the entire thickness of the wall. The remaining space can easily be covered by an extension installed after installation work..
As soon as the drawing with dimensions is completely ready, you can move on to the next stage of work. At this stage, the material should be processed and the frame of the door leaf should be prepared. To do this you should use a plane.
For the frame of the door leaf you need to use planed boards For the frame you can take edged board 40 x 100 mm. Ideal option you will purchase planed material, which will make the work easier and significantly speed it up. But you can also use simply sawn boards. They will have to be processed with a plane to make them smooth. During planing, you should carefully monitor the corners of the bars. They must have a strict 90 degree angle. You can check the work using a square.
Connection diagram of frame elements Next, the parts are marked according to the dimensions indicated in the drawing. They will need to be sawed off. If the parts must be secured with tenons, then all horizontal parts of the frame will be longer by the size of two tenons. For example, for bars 100 mm wide, a tenon 70 mm long will be required for connection. In this case, 140 mm should be added to the size of the workpiece, which means two tenons on both sides of the part.
During processing, it is necessary to select a groove or quarter in the sides of the workpieces. This is necessary for installing glass or inserting panels if solid wood was chosen as the door manufacturing option. This work can be done using a hand-held electric router. A cutter of the appropriate profile is inserted into the tool and a cut is made on the side indicated in the diagram.
The groove in the workpieces is cut using a router Details for door frame must contain a quarter, thanks to which the canvas can cover the opening. It is also made with a router, setting the depth and width of the cut. The size of the quarter should be based on the thickness of the door leaf. You need to add 1 mm to it for a better rebate. The depth of the quarter must be at least 10 mm.
When the frame parts are processed and the places for the fasteners are sawn down, preliminary assembly of the interior door leaf can be done with your own hands. This operation will allow you to check the correctness of the marking and filing of all elements. The structure is assembled dry, which means without using glue. If the type of connection was chosen to be confirmed, then you will simply need to bait them without performing a tight twist.
When all the parts are assembled and fastened, check the width and length of the door leaf. If deviations from the drawing are found, then it is necessary to adjust the parts. After finishing work, the product is reassembled and inspected. If all parameters are met, you can proceed to the next stage.
Separate mention should be made of marking parts and making cuts. This step by step process, where an error can result in reworking the entire product and damaged material. Therefore, all pencil lines should be made only after checking the size. And before starting sawing, the marking itself should be checked against the drawing.
When marking, you should strictly adhere to the dimensions When marking, you can add 1 mm for adjustment. In this case, even if the workpiece is sawed off unevenly, it will be possible to correct it painlessly. If everything works out the first time, then the extra millimeter can be simply removed with a plane. To transfer the drawn line to the other side of the block, you should take a square and place it directly at this point. Since the part has an even angle of 90 degrees, the lines on all sides will exactly repeat the markings made at the very beginning.
If spikes and eyes are chosen as a connection, then you will have to completely mark these elements. The place for the nest should be located strictly in the center. To calculate this data, you simply need to divide the thickness of the bar by 2, and then mark the resulting number from any plane of the part. The size of the tenon itself should be equal to 1/3 of the thickness of the workpiece. The width of the nest can be half a millimeter less than the width of the spike.
The eye should be carefully drilled strictly according to the markings made, and then cleaned with a chisel. You cannot protrude beyond the edges of the lines, otherwise the connection will be weakened and the structure will be fragile. According to the instructions, it is necessary to precisely adjust the tenon joint, so it is imperative to leave a half-millimeter margin.
When all connections have been checked and the dimensions exactly match those indicated in the drawing, assembly of the door leaf begins. When making a tenon joint, it is necessary to smear the plane of the tenons with glue and inner surface nests After this, the parts are inserted into each other, followed by tamping with a mallet. If this procedure is performed with a hammer, then a small wooden block onto the tamped surface. This way you can avoid damage to the assembled product.
After assembling all the parts, there should be no gaps left at the joints. If they are present, then you should knock out this place again. The ideal option would be to tighten the canvas with webbing. If they are missing, you can install a metal corner on the board, measure the width of the canvas from it, add 3–4 cm to this size and secure another corner. Three boards are needed on which the door is laid. A wedge is inserted into the gap between the canvas bar and the corner and tapped until the cracks completely disappear.
The door is assembled until the cracks disappear Once the door is assembled, the trim is attached to its surface. First, the sheets are cut to fit the frame and then laid on it. Fastening is done using glue. Additionally, nails can be used. This operation must be performed carefully and carefully so as not to damage the surface of the cladding, especially if it has a finishing coating.
Before laying the second sheet with reverse side The filler is installed on the interior door. To do this, foam plastic or cardboard honeycombs are cut to the size of the free space. internal space between the parts of the canvas. A tight fit will ensure the integrity of the future door. Next, the second sheet of cladding is laid and the canvas gets its finished look.
In order for the door to open, you need to install hinges. They are located at a distance of 20 cm from the edges of the door. The markings are made with a finely sharpened pencil. The nest must be selected with a chisel strictly along the inside of the line, without protruding beyond its limits. The hinges in the seats must fit without gaps. When the socket is ready and checked, the part is fastened using self-tapping screws or the screws included in the kit. Read more about this in the article “Installing hinges on a door.”
Door hinges secured with self-tapping screws or self-tapping screws Another element of an interior door is the handle. A lock is often inserted into it, which makes it possible to lock the room if necessary.
The hole for the lock is made using a drill The center of the handle should be 1 meter from the floor. A through hole for the lock is drilled with a drill. Seat also cleaned with a chisel. Once the lock is inserted, there should be no gaps left. Read more about installing a handle on an interior door.
If the interior door requires glazing, then you need to prepare a glass cutter and select the desired type of glass. This element is inserted into a quarter, which is selected along the entire inner perimeter of the door. The glass is cut 2 mm smaller than the size of its installation space.
Glass cutting is done with a glass cutter If after working with a glass cutter the sheet has irregularities, they must be removed. You can use pliers for this. At large balance(from 2 mm) another cutting line should be drawn. This will make it easier and more efficient to remove excess. When the procedure is completed, you need to sand the edges of the glass with sandpaper.
Next, the glass is installed in the quarter of the door. Fastening is done with a decorative layout, which is nailed down with small nails. This ensures the possibility of quick repairs if the installed glass is damaged.
The assembled door, if it is not covered with laminated chipboard, needs to be finishing works. They can be of the following types:
Depending on the type of finishing chosen, appropriate operations must be carried out.
Before painting the surface of the door leaf, it is necessary to prepare it. And the first thing to do is sand it completely. An electric one is ideal for this purpose. Sander. You need to take a tape for it that is not too abrasive, so that it does not remain on the surface. minor scratches. You need to work in the direction of fiber growth. Perpendicular grinding is allowed only if it is necessary to level the surface and as a rough grind.
Before painting the door, its surface must be sanded. If there are any chips or dents on the door, they should be filled with putty. The color of the putty must be selected to match the shade of the wood from which the canvas is made. So, during subsequent painting, this place will not stand out from the general background. After applying the putty, you need to let it dry and sand it again.
Defects wooden surface remove with putty Next, you need to clean the surface from dust and only then start painting. To apply the material, brushes, rollers or paint sprayers are used. Last option allows you to complete the job quickly and with minimal paint consumption. There should be no drips on the surface during painting. They need to be removed. To get a quality painted door, you need to apply two or three layers of paint..
The door must be painted in 3 layers Unlike painting, door tinting involves the subsequent application of varnish. You need to apply a tinting material to the prepared surface, which can be:
Either type of material will give the wood a new color while leaving the grain exposed. The stain is applied with a brush, roller or spray gun. If necessary, repeat the procedure after the material has completely dried.
Wood stains, mordants or paints are used as tinting materials. When the desired shade is achieved, the canvas is varnished. To achieve a glossy surface, more than three coats should be applied. Moreover, each stage involves sanding with a fine sanding belt. This will remove raised lint and make the surface smooth.
An alternative paint and varnish materials is the use of films and veneers. The gluing of these materials is called lamination. For home production the best option will cold method gluing.
The surface of the interior door must be prepared in the same way as in the case of painting or tinting. The film or veneer is cut to the size of the door leaf, making an allowance of up to 3 cm. Then, starting from one edge, the material is glued. If a self-adhesive film is used, then the protective paper is gradually removed from it as it is glued to the surface of the door.
Self-adhesive film used for door lamination The veneer is applied to glue, which is used to pre-lubricate the canvas. The material should be smoothed from the middle to the edges. This will make it easier to remove air trapped under it. If the bubble cannot be expelled, then it can be carefully pierced with a needle. This place must be pressed firmly so that the adhesive layer can connect the surface of the door and the veneer. Excess material around the edges is carefully trimmed with a knife.
Excess film is removed with a knife
