How to sew a doorway using drywall

The main task of overhaul - to make housing more beautiful and functional. Often this is due to the changing location of rooms. Some of them are combined, others, on the contrary, are divided into smaller, but separate rooms. When doing this work, it is often necessary to change the location of doors, after dismantling of which remains a large and unsightly hole. Let's talk about how to sew the doorway as quickly and inexpensively.

Overview of materials

The following building materials are used to sew the doorway:

• plywood,
• OSB plates,
• brick,
• gypsum board.

Plywood is a fairly strong material that is easy to use and does not require large expenditures for additional consumables. Nevertheless, like any wooden product, plywood is highly prone to moisture. Since the opening in the door, even with high-quality insulation, will still be a source of draft, a condensate will necessarily appear on the surface of the plywood sheet, which will lead to the wetting and delamination of the sheet elements. As a result, the wall will lose its appearance and completely deteriorate. As an option, waterproofing impregnations are used, but they significantly increase the cost of the structure.

OSB-plate is more reliable, but not much. The reason is still the same - excess condensate. Although the process of soaking will take much longer and take 4-5 years, but ultimately the plate will still not be usable.

Brick is devoid of these drawbacks, but its cost, as well as the cost of the solution - is a significant disadvantage. In addition, work involves the presence of a large amount of dirt, which then is difficult enough to clean. If we are talking about an apartment, then there is one more question - what is the solution to mix? Small dishes are uncomfortable, since you have to knead cement every 10-15 minutes, and there is nowhere to put a big one.

Against the backdrop of these standard methods, drywall looks like the most suitable option. First, working with it is very simple, secondly, the consumption of materials is minimized, and thirdly, the design, like a brick, will last almost forever. If we talk about condensate, then for gypsum it is not terrible. The material works like a sponge filter. The paper absorbs moisture, which immediately takes up the gypsum, while drying the paper coating. Further moisture passes to the front of the sheet of drywall and gradually dries. In addition, modern technology allows the use of moisture resistant gypsum board impregnated with hydrostatic additives.

We prepare all the necessary

To work on a certain set of tools and supplies:

• perforator / drill,
• screwdriver,
• set of screws with dowels,
• set of screws for metal profile,
• set of screws for gypsum,
• level,
• rule( at least 1,
• putty,
• spatula,
• tape measure,
• hammer,
• construction knife,
• bulgarian / metal scissors,
• mounting foam,
• 2-5 sheets of drywall( depending on doorway dimensions),
• rer.

A few getting ahead( because the finished surface still has to be decorated with wallpaper or paint), it is worth immediately buying a primer and fiberglass paper if you plan on painting the walls.

How to sew a doorway with drywall

Before starting work, you need to create a sequence of actions. It looks like this:

• door dismounting,
• cleaning of the doorway from debris, pieces of plaster, remains of the box,
• garbage removal,
• dimensioning,
• frame assembly,
• plasterboard mounting,
• finishing work.

The dismantling of the door takes place primarily, firstly, it is the dirtiest work, and secondly, it is associated with certain disruptions, on the extent of which the course of the subsequent installation of the plug depends. Technologically the process is simple enough:

• remove the door from the hinges,
• remove the trim,
• unscrew the screws from the box( if any),
• cut parallel to the ground along the top and bottom edges of the side strips,
• remove one of the side strips,
• dismantle the top,
• dismantle the remaining parts.

Next, look at the result and proceed to clear the doorway of debris. If the work is done carefully, the wall will not suffer, otherwise pieces will be broken. It is not necessary to seal them at this stage. With a hammer, carefully discard all excess garbage( pieces of plaster, broken stone, etc.).The end result is a smooth, even surface( you do not need to bring to an ideal, the main thing is that the rule should be straight to the end of the wall).

Garbage collection is mandatory, as it will interfere with the work, shards of plaster or stone can damage the drywall, in addition, it is harmful for health to work in the dust.

The next step is to size. This procedure should be taken as carefully as possible. In order for the final result to coincide with the planned one, we recommend the following algorithm:

• to measure the perimeter( for example, the opening size is 85x185 cm),
• to calculate the number and dimensions of the supporting profiles for the frame( to ensure maximum impact strength, the support bars are set every 20 cm,85 cm is enough for 5 supports, two on the edges and three on the center, their length should be 195 cm, 185 - the main height and 5 cm from the top, and bend downwards for fixation with screws in the floor and ceiling),
• calculate the quantities(bulkheads are installed only if it is planned to hang something on plasterboard.) It is necessary to accurately remember or mark their location, since the fixation of the hinged structures must take place directly in the metal. Install one guide, which will have to be loaded, and on the sidesfrom it two fixing bulkheads at a distance of 20 cm from the central one),
• calculate the necessary number of sheets of gypsum board( standard sheet dimensions - 120x250 cm, therefore, only two pieces if the openingSobienie, the individual calculations),
• count the heater( this area know the structure of Example 86h185 = 1.6 sq.m. It is worth noting that the insulation must be placed in two or even three layers, depending on the thickness of the opening. Thus, the number of insulation is given by the formula: perimeter area x( wall thickness / material thickness) .In this example, if the brickwork is brickwork and the mineral wool insulation material, the formula looks like 1.6x( 10/5) = 3.2 square meters.m.

Rough work done, now go to the most important.

Mounting the frame

If the dimensions were removed according to the specified algorithm, the assembly of the frame will take no more than an hour. Work begins with cutting the profile. A hand-made Bulgarian is easy to perform, but if the profile metal is of low quality, then it will become brittle from overheating, so it is better to use metal scissors. The work is most conveniently performed by two people - one saws, the second fastens.

Once the parts are cut, go directly to the installation. First of all, the support bars on the sides of the structure are installed. This is done as follows:

• for 5 cm along the length cut and bend the edges of the profile( so that the heel turns out),
• strip is used in the opening, it should go freely( otherwise cuts are made a little more),
• through the legs, screwed into the heels of screws( at the beginning to the ceiling),
• if the material is a stone, we use dowels( for concrete anchors),
• check the level with the angle( should be ideal 900, otherwise the design will lead),
• screw the bottom heel,
• check the rule( there should not be "belly"),
• check the level.

It is impossible to put the supports in the spacer, as they will bend and create an arc that, first, breaks the strength of the structure, and secondly, leads to uneven surfaces.

In the same manner, the other straps are mounted. After completion of work, it is necessary to put a rule parallel to the ground. It should fit perfectly smoothly. The rule is set to the level and the angle is checked against the wall, it must also be 900.

If it is necessary to install the bulkheads, it is done as follows:

• measures the distance between the supports( in each case separately),
• to the resulting value is plus 6 cm,
• at the edges are made heels( 3 cm),
• screw-up for metal profiles is screwed to the support.

Even if the planned hinged construction does not occupy the entire parallel of the drywall, the bulkhead needs to be installed between all the supports, otherwise they will not perform their function of evenly distributing the load on the frame.

The next construction for the other side of the wall is assembled. Even more detailed will show how to sew the doorway, photo:

Board : in order for the sheet to fit perfectly smoothly, it is necessary to measure its thickness, the value indicates the distance that should be retreated from the edge of the wall to the edge of the profile.

Installation of drywall

This is the most pleasant part of the procedure and takes only 20-30 minutes. As in the case of the profile, the work begins with the cutting of the material. To do this, we use the rule and the construction knife. To make the cut turned smooth, you must apply the rule from the front side, with medium strength to draw a line and then, with a light blow, break the sheet. It will hang on the fold of the rear paper, which is cut through the boat.

Technology cutting sheet drywall includes another fundamental point - they always start with a narrower side. Thus, the first thing to gain height, then the width( cut completely extra length, then one edge is used as a base, mark with the help of a tape measure the necessary width and make a second cut).

If the frame is assembled correctly, just attach the sheet and begin to screw it, first to one of the side supports. The distance between the screws should be about 15 cm. It is very important to drown the head of each screw in the gypsum, otherwise it will damage the decorative material or ugly will protrude in the plaster. Each support is screwed in series.

If the work is done alone and there is no one to support the sheet, then first all the central screws are fastened, then the bottom and top. This will fix the sheet and allow you to calmly finish the work. On how to sew up the doorway with plasterboard, the video from the article will tell more clearly.

Several variants of finish works

Wired doorways, photos of which are placed by various construction companies, will be very different from the result you get. The fact is that it is not enough just to lay an opening, still it is necessary to conduct decorative finishing works.

First, you need to fill the heads of screws in the plaster and the places where the sheets are joined( if any).This is done in order to create the most flat surface. Similarly, you should deal with the seams between the plaster and the wall.

Secondly, between the sheet of gypsum and the wall, large crevices are often found. Naturally, they can be laid with cement or putty, but much easier, and also more economical, blow out with mounting foam. Surpluses are then cut off, and the foam itself shpaklyuetsya.

Third, the question of external surface finish remains open. Actually there are only two of them:

• painting,
• wallpaper.

Everything else follows from them. If the front side of the sheet is white, then there are no questions. But in the case of moisture-resistant cardboard, the surface will have a blue or green color. In addition, most of the putties are stained, both on the wallpaper and on the paint. To solve a problem it is simple enough - a glass paper. It is a thin white material with high adhesion. Despite the fact that it increases the consumption of paint or wallpaper glue, its properties are very useful, since they significantly prolong the life of the wall covering( exclude cracking of the paint).

In order to paste glass paper, it is necessary to treat the surface in the beginning with ground, then with liquid PVA adhesive( only for bricks).The paper itself is glued to wallpaper glue. Absorbent effect( and with it the consumption of paint or wallpaper glue) will decrease if the paper is primed.

If the issue of economy is not worth it, it is desirable to paste glass paper not only on the doorway, but also across the entire wall area( materials, on average, will last 5-10 years longer).
