What to make under a plastic window sill. How to properly make a window sill on plastic windows with your own hands: step-by-step instructions, video. The process of preparing concrete mortar for a window sill

Window sill is not easy decorative element window design. It contains important, multi-component functionality. Make window sills on plastic windows- this is only half the battle; they still need to be made functional, reliable and safe.

Endurance must be inherent in the new design. Suddenly you want to put a large pot or you need to stand on it to wash the windows, replace the curtains, and you never know what else you need to do. It is better to initially make a durable window sill with your own hands.
Changes temperature regime the window sill is affected throughout the year. In summer it heats up, and in winter it is exposed to hot air from the battery on one side, and frosty air from the other. open window which is open for ventilation. When choosing a material, this factor must be taken into account.
Humidity can appear from watering flowers, condensation and other factors.
The beautiful appearance of the window sill is the key to a cozy atmosphere in the room.

We found out how to make window sills on windows with our own hands. And now nothing prevents us from moving on to the practical part of the conversation.

This design usually has good foundation and meets all the requirements described above. We will describe how to make window sills from tiles in the following instructions.

If there is an old concrete window sill left near the window, then the work is greatly simplified. In this case, you will need to remove the paint and putty. In this case, you may need an ax, a crowbar and other tools, since there are often many thick layers, to dismantle which you will have to use brute male force.
The free surface will need to be leveled using a solution. If there are “ears” that protrude from the wall, you will need to dismantle them.
A wooden window sill for plastic windows can also be tiled with your own hands. In this case, drywall is mounted on the tree and a damping layer is created. After these manipulations, you can proceed to the next steps.
Lay the tiles on a prepared and primed surface. It is better to start from the middle and move towards the slopes. If necessary, the tiles are cut according to the dimensions of the structure.
At corner joints, the edge should be cut at an angle of 45 degrees. Decorative corners can be used.
Special attention should be paid to the inside of the window sill, which hangs above the radiator or floor. It is not visible and you don’t have to worry about aesthetics. But it will be necessary to ensure a drop arrest. To do this, you need to create an angle of inclination that will be directed inward. You can't make a right angle. Finishing can be done using putty and paint, for example.
To install tiles, any adhesive that is intended for these purposes can be used. The seams should not be wide as they tend to clog and crack. And in the future they will cause a lot of headaches.

This way you can make window sills and slopes on the windows. And you don't have to use a whole tile. Multi-colored pieces will create an exclusive mosaic that will transform the entire window structure.

Previously, this material was used very often for the production of window sills. Time passes, everything changes, but this trend remains unchanged. Even the popularity of plastic is not replacing wood. We will tell you how to make a wooden window sill for plastic windows and you will see that this process is not difficult.

For this work, you should choose hardwood, coniferous or hardwood materials. You should not choose a planed board, but prefabricated glued factory elements can be used. Creating a high-quality typesetting board at home, which will consist of various types of wood, and covering it with durable plastic is an unrealistic task. It’s a completely different matter to prepare a regular, solid wooden board. Anyone can handle this.

Thoroughly dried wood is suitable for making boards. The thickness of the board should be within 4-5 cm. It is very rare that you come across a board of the required width; it is not worth wasting time looking for it. You need to take two or even three boards, the total width of which will be equal to the dimensions of the working surface. Glue is suitable for joining boards, and its effect is enhanced and secured with dowels. The hairs of the boards should have different directions. This trick will help avoid the formation of tension from excess moisture or uneven heating.

In this case, a laminated chipboard is used for work. This material has a large number of colors and textures, giving designers plenty of room to roam. The chipboard sheet is covered with PVC film on both sides. The film is pressed with the base material, which makes it possible to achieve solidity. Moisture does not harm such material.

All work comes down to cutting the workpiece according to the layout of the future structure and gluing the ends. After this, the window sill can be installed in place.

This material, like wood, has been used previously and is still used today. So it’s not surprising that many modern users are interested in how to make a concrete window sill with their own hands. Welcome to use decorative compositions with crumbs natural stone. You can also use special kind cement is decorative, it has a beautiful White color.

Such a structure can be made immediately in the window opening or created in another place, and then transported to work surface. In the first case, the window sill will not need to be installed, but the polishing and grinding processes will be more complicated. Hand tools It will be difficult to achieve the desired result; it will take a lot of time, effort and nerves. A grinder or grinder with a suitable disc is a completely different matter. How to make a window sill on concrete windows - in the opening or in another place - is your business and no one can make such a decision for you.

To form the formwork, it is convenient to use boards or sheet materials with sufficient strength. The edge of the board can be decorated with a figured profile. To make the window sill strong, it is necessary to carry out reinforcement. Frozen surface needs to be sanded.

When polishing is completed, you can begin impregnation. These compounds will add strength and make the structure durable. You know how to make a concrete window sill with your own hands, now everything is in your power.

No one will describe the creation process plastic profile because it is absolutely impractical. Usually a ready-made profile is purchased, which is cut to the required size. The ends are closed with plugs. This completes the work.

Of all the methods, this is the easiest and fastest. But to wooden windows It is not advisable to install plastic. In addition, this material is not as strong as wood or concrete. In any case, you know how to make a window sill for a plastic window yourself.

This material has found many applications, including in the field of creating window sills. Nowadays, window sills are increasingly being created in the form of a table or multifunctional shelf. You can create such a structure using drywall. Practical guide, which is located below, can be used by a person who is interested in how to make a window sill on a balcony with his own hands.

Work begins with the installation of the frame:

We remove the mounting foam that remains after installing the window.
We fix the frame under with self-tapping screws window frame. There should be gaps under it that will allow you to install the gypsum board without any problems.
To fix the upper part of the window sill, it is necessary to old window sill attach small profiles.
Now you can attach the top profile to the window sill, having previously inserted it into the horizontal elements. The location of the parts must be checked with a level.
On short products it is necessary to place profile guides.
To attach the guide, select the ledge of the window sill. In this case, the structure will be rigid and even take on an unusual appearance.
We attach an additional profile from the end. This will make the structure voluminous and increase the margin of safety.
We connect all the parts together with self-tapping screws.
Vertical guides are necessary to increase the thickness of the structure. The point of their attachment will be the upper profile.
At the bottom we place a long profile and fix it with the help of short ones that are already installed.

After this stage, you can proceed to the installation of drywall. This work is performed as follows:

We take measurements from the frame and mark the location of the guide profiles. In this case, it will be possible to accurately position the screws and at the same time maintain the integrity of the skin.
Carefully fill the seams between the sheets and the opening with sealant.
After completing the covering of the lower part of the frame, you can fill the distance between the profiles with foam. Such actions will make the structure warm.
We fix the upper part on top and fasten the sheets with self-tapping screws.

This is how you can still improve plastic windows; it’s easy to create slopes and window sills with your own hands from plasterboard.

We told you what window sills for plastic windows are made of and looked at each option. The next conversation will explore slopes. So very soon you will know how to make window sills and slopes on windows. And if you also practice, you can be considered an expert in this field.

After all those construction work, which you and I have already learned to do on our own, installing a window sill with your own hands will not be difficult. Window sill installation includes all the main stages and conditions that are necessary for any type of work. This includes preparing the base, having the necessary tools and materials, and the process itself. Please note that in each article we drew your attention to the fact that a satisfactory final result, no matter what construction or repair work This did not concern, it is not so much the ability and skills that influences, but a scrupulous and responsible approach to work.

Having all the necessary tools at hand important condition for quality work done. Working with modern construction adhesives, mounting foams and sealants requires strict adherence to time schedules. It may happen that after applying, for example, polyurethane foam, you suddenly discover that the level is missing. Spending a few minutes searching for it will be enough for the foam to set. And if it suddenly turns out that the window sill is installed with an insufficient slope, consider that you can start all over again."Drill and screwdriver" "Jigsaws, reciprocating saws, planes, milling machines"

Installation wooden window sill

Before installation, it is necessary to prepare the surface, thoroughly clean it of construction debris and dust, and moisten it with a little water for better adhesion of the base and the mortar. The wooden window sill blank should be 4cm longer than the length window opening and a maximum of 10cm wider. If the slopes are made perfectly level, you can install the window sill flush with them. The uniform rule for window sills of any materials is the angle of inclination into the room relative to window frame should be exactly two degrees, no more and no less. If you install the window sill clearly horizontally, then, not to mention the possible accumulation of condensation, but even carelessly watered flowers will create a lot of problems. If the slope angle is too large, then whatever you put on the windowsill will simply roll off it. With all the desire to do wide window sill, we do not recommend increasing the width by more than ten centimeters relative to the width of the window opening. . Because of this, the windows will begin to fog up, which will lead to excessive condensation accumulation. "Wood stain"

When wooden blank cut to the required size, using pre-prepared spacer wings, install the window sill level. Small quantities solution, secure the wedges in the desired position. They will serve as beacons for you. Then apply the solution to the surface half a centimeter higher than the beacons. “Plastering correctly.” The solution must be selected in accordance with the room in which you are installing the window sills and depending on the material from which the window sill itself is made. If the room is poorly heated with high humidity Cement mortar with waterproofing additives is better suited. For normal conditions, a gypsum solution or one made from putty is suitable. Additionally, it is recommended to secure the wooden panel with self-tapping screws. At the junctions of the window sill with the walls and window frame, possible cracks must be sealed with acrylic or sealant.

Installation of a plastic window sill

The most common installation method pvc window sill, on polyurethane foam. The same as in the previous case. Prepare the base and cut it out right size. If you use two-component polyurethane foam, which does not expand in volume as it dries, you can do without spacers. If a plastic window sill is installed on ordinary foam, the surface of the window sill should be rigidly loaded with spacers to prevent deformation and shifting. . After this, secure the end plastic linings, to hide the cropped places.

After this, secure the end plastic covers to hide the cut areas.

The process of installing these window sills is practically no different from installing other types of window sills. The only thing is that professionals do not recommend using polyurethane foam in this case. A natural stone- a porous material, and the foam in the process of swelling, entering the veins, can damage the structure of the stone.

Not so long ago, window sills made of high-strength plastic were especially popular, but last years Once again there is a tendency to return to natural materials. If earlier they were not so attractive and comfortable, they were simply painted in a boring white color, but now the lineup has become much wider.

Modern window sills are beautiful and extraordinary; they are covered with stains and varnish. Making a wooden window sill with your own hands is not so difficult; to do this, you just need to have some skills in working with tools and wood, and strictly follow all the steps of the instructions.

There are many advantages of using wood for window sills, among them the following should be noted:

The material is environmentally friendly and completely safe. It does not emit harmful and toxic substances and is not allergenic.
When the heating is turned on, the heat from the radiators has no effect negative influence on wood, as can happen when using plastic.
Window sills from natural wood are more reliable and durable, they can withstand various loads.
The coating will look stylish and expensive, especially if you use not standard paint for finishing, but glossy or matte varnish, or oils that are used to impregnate wood. This will make the surface stylish and expensive, especially if the window frames are designed in exactly the same way.

How to make a presentable window sill?

Making a wooden window sill with your own hands is not as difficult as it might seem. Of particular importance is what kind of material will be used for the work. It should be a perfectly dried board that has no knots, cracks, or defects. The board should be carefully processed, given the desired style, and a selection of moldings and teardrops should be made.

Teardrops are small grooves, the width of which is 8-10 mm, with a recess depth of 6-8 mm. Such a groove is made along the bottom of the board, approximately 1-2 cm from the front part.

After such pre-treatment, it is necessary to cut the window sill board to the required length. This takes into account the width of the window opening plus 4 cm for each side. This size will be quite enough for a window sill.

Often the board for a window sill is taken not as a single piece, but as a composite one. This ensures reliability and durability. To connect the boards, wood glue, dowels and dowels are used. During the manufacture of the window sill, attention should be paid to what the dimensions of the structure will be.

The length of the window sill, as already mentioned, should be at least 8 cm greater than the width of the window opening. If there is a need for additional reinforcement, then it can be made about 10-15 cm larger, but this will make the selection of wall material more difficult, this should not be forgotten.

It is important to pay attention to the protrusion into the room. You can make the width so that the window sill is flush with the wall, but this is inconvenient for a number of reasons. The optimal design is considered to be when the width is approximately 6-7 cm larger. Such a window sill will be convenient to use and will serve as an excellent frame for the window opening. Too large a protrusion is inconvenient from the point of view of using the window; it will be difficult to open the sashes. Wide boards can be installed when the window sill is installed in the kitchen. Here it can act as a convenient tabletop, which is useful for arranging utensils, seedlings, or as a compact table for eating. During manufacturing, we must remember that wood needs excellent protection from moisture. To do this, it is necessary to treat the boards with an antiseptic. This will protect them from rotting and the harmful activities of insects.

Installation of a wooden window sill: step-by-step instructions

To install a wooden window sill with your own hands, you must first clean the future installation site, and then cover the bottom with shingles and felt. This will insulate the structure, eliminating blowing and heat loss.

The installation itself is done using a solution based on lime and gypsum. In this case, you need to ensure that the window sill is tilted approximately 3 degrees into the room.

Wooden wedges are used for installation, after which lime-gypsum mortar is poured. It should be poured approximately 1 cm higher than the level of the wedges. After this, all excess is carefully removed.

The installation of a wooden window sill itself is carried out in this way:

After preparatory work After installing the wedges and pouring the mortar, you need to start laying the boards. It is mounted from the bottom of the window opening. 4 cm is added from each end of the board. This distance is necessary for laying the window sill into the slopes of the wall. Usually this amount is enough for the window sill to be installed firmly, not to become loose, and not to warp even under fairly heavy loads.
For the window sill itself, it is best to take a board with a thickness of 5-6 cm. If you need to connect several boards, you will have to use quarter-length fasteners. The boards are additionally secured with transverse dowels. By inside you need to place a special gutter with a depth of approximately 6-8 cm.
If the wall is stone, then you need to carefully clear the grooves, and then adjust the board for installation. The ends of the board and the lower part must be covered with felt. This will allow the structure to be insulated more reliably.
Using a building level, the board is aligned horizontally; distortions are unacceptable.
After installing the board, you need to carefully fill all the gaps construction plaster. It is pre-diluted in the required proportion. After installation, walls that have been damaged must be carefully plastered and then decorated in accordance with the overall finish.

Usually installing a window sill, plastic slopes and low tide occurs immediately after window installation. In most cases, this is done by a team of builders specializing in metal-plastic structures. But there are times when it becomes necessary to install a window sill with your own hands, and we’ll look at how to do it correctly in the article.

There are various reasons why there is a desire or need to install a window sill with your own hands:

The window is in good condition, but the window sill is damaged (dirty, scratched, melted, burned, etc.).
The old window sill was installed incorrectly.
There was a desire to install a window sill of a different color. For example, after renovation of a room, the color of the PVC plate does not match the new interior.
There is a need to replace the window sill with a wider or narrower one. A wider window sill is installed if you need to place a large number of objects on it, for example, pots of flowers or seedlings. A narrower window sill may be needed if too wide one interferes with the free movement of warm air from the battery upwards and the air circulation in the room in cold period of the year. Wherein warm air The battery does not heat the window, it “sweats”, dampness and even fungus appear.
It is difficult to find a craftsman who will take on such a small amount of work as installing one window sill.
Installing a window sill yourself is not at all difficult, and you can save money that could have been spent on paying a specialist.
It's just nice to make something useful with your own hands.

Important!A wide window sill visually enlarges the room and its usable area.

So, if there is a need to replace a PVC plate, you need to know that window sills are different:

flowers, except light and dark shades there are imitations of stone and valuable species wood;
dimensions: width from 110 to 800 mm, length from 4050 to 6000 mm, thickness from 18 to 22 mm;
company and country of origin;
price (from 3 to 20 dollars per linear meter);
the quality of the material - polyvinyl chloride, including resistance to wear and scratching, resistance to heat, moisture and steam resistance, resistance to ultraviolet radiation, environmental friendliness, strength.

Did you know? Polyvinyl chloride has a very wide range of applications. Condoms are even made from PVC for people with latex allergies.

In addition to the window sill itself, it is necessary to purchase two end caps, which are installed on the side sections of the window sill at the final stage installation work. If there is a need for direct or corner connection two window sill boards, you should purchase a universal corner connector for PVC boards.

Required tools and supplies

For high-quality installation of a plastic plate with your own hands, you will need the following tools and consumables:

Metal square.
Marker or pencil.
Roulette.
Primer.
Grinder, jigsaw or hacksaw.
Hammer (not necessary, only if the slope material is dense concrete).
Chisel and hammer.
Brush.
Building level.
Construction foam and gun.
A set of plastic supports or wooden blocks.
Cement, gypsum mortar or glue for installing bars to the required height or for raising the level of the base.
Sealant.
Masking tape.
Stationery knife.

Installation process

Regardless of whether the window sill is installed by a specialized installation team or by a person new to this business, the entire process PVC installations slabs can be divided into several stages.

Preparatory stage

You should prepare the place where you plan to install the PVC plate, namely the lower part of the window opening and the side window slopes. The window sill should fit slightly into the wall on the sides, therefore, in the slopes it is necessary to cut connectors 1-2 cm deep on each side in order to insert a plastic plate there. To do this, the window sill is applied to the wall and marks for cuts are made with a pencil or marker. Next, carefully select the grooves so that the window sill fits freely into them. This work requires care so as not to restore grossly damaged slopes and not to fill large holes in the slopes.

Important! In order to minimize the procedure for restoring slopes, you should treat them as carefully as possible during the installation of the window sill.

If the corners of the slopes were leveled using metal perforated corners, then you should carefully trim metal corner using a grinder. It is also advisable to use a grinder to make a horizontal cut in the slope. It is convenient to make the rest of the recess in the wall using a chisel and hammer. These tools are most suitable if the slope material is gypsum plaster. If the slopes are made of concrete, then the recesses in the slope should be made using a hammer drill. The side grooves in the slopes serve as additional support for the window sill on the sides.

The lower part of the window opening and the stand profile, which is located under the window frame and is used to install the window sill, should be cleared of pieces of plaster, concrete and brick that appeared during the process of creating grooves in the slopes. Then use a brush to sweep away all remaining debris and dust. The cleaned surface should be moistened. This is necessary for better adhesion of the polyurethane foam to the surface on which the window sill will be located. It is advisable not just to wet the surface with water, but to use a primer for these purposes. The soil strengthens the surface, removes dust and moisturizes it at the same time. Using a brush, generously apply primer to the surface, saturate all the holes, bulges, pores, and cracks.

Important! In order to prevent blowing from under the window sill, you should check the quality of the foaming of the window frame and, if necessary, eliminate all deficiencies in the preparatory stage works

Window sill trimming

AND Having a finished window sill, you need to cut out a blank for the window sill from it. To do this, you need to calculate the length and width of the future window sill. The length of the window sill must be greater than the length of the surface for the window sill and extend beyond the slopes. The length of these protrusions depends on individual taste preferences, usually 5-7 cm on each side, but you can limit yourself to a protrusion of 1-2 cm.

The width of the workpiece is calculated by summing:

width of the window sill surface;
the depth to which the slab is inserted under the window into the stand profile (usually about 20 mm);
the protruding part of the window sill, which should not be more than 100 mm, so as not to interfere with the passage of heat from the battery.

Rectangles should be cut along the edges of the window sill, which prevent the canvas from sliding downhill. The plastic sheet is cut quite easily. You can choose any cutting tool: grinder, hacksaw, jigsaw. All nicks, irregularities and other small cutting defects will be covered with plastic end caps.

After the workpiece is ready, it needs to be tried on in place, that is, placed on the lower part of the window opening and placed into the recesses of the slopes and inside the stand profile. If any inaccuracies are identified during fitting, they should be eliminated before the final installation of the window sill.

Gasket Installation

Some installers install the window sill strictly perpendicular to the window and use a metal square for control. However, most experts believe that a properly installed window sill should have a slight degree of inclination into the room, so that if moisture appears, it will flow down.

To fix the desired installation option for the window sill blank, you need to place plastic spacers or wooden blocks. Their dimensions must be selected so that the surface of the PVC plate is perfectly flat. To install one window sill you need at least 3 supports (one in the middle and two closer to the edges). The distance between supports should not exceed half a meter. To prevent the spacers or wooden blocks from moving, it is advisable to glue them to silicone sealant, gypsum or cement mortar.

Important! The process of fitting and installing a PVC window sill must be constantly monitored by the building level.

The supports of the window sill should be placed at such a level that when trying on the window sill blank, no gaps will appear between the window sill and the window frame. If, to comply with this requirement, the supports are higher than 40 mm, this is unacceptable. A layer of foam exceeding 40 mm will not be of high quality, it will have voids, it will not be able to withstand the required load, and the thermal insulation properties will be insufficient. In this case, before placing pads under the window sill, you need to raise the level of the lower part of the window opening. This can be done with cement or gypsum plaster, self-leveling floor, etc.

Installation

At the preparatory stage of installing the window sill, we cleaned, strengthened and moistened the lower part of the window opening with a primer. By the time the window sill is installed, the primer has already dried, and for better adhesion and accelerating the hardening process of the foam, the surfaces with which it will come into contact polyurethane foam must be wet. Therefore, it is necessary to moisten both the lower part of the window opening and the lower part of the window sill. PVC coated board protective film. The edges of the window slab that will be mounted under the window frame and in the openings of the slopes must be cleaned of protective film.

It is advisable to keep the film on the remaining parts of the window sill until all repair work is completed. To prevent wind from blowing from under the window sill, the first thing you need to do is lightly foam the space between the bottom of the window opening and the window support profile. Then the foam is applied in a wide strip under the far edge of the window sill, and then in dense strips over the entire plane of the base. For ease of foam application, additional extension nozzles are used.

Important! The height of the foam should not be greater than the level of the supports placed under the window sill. When foaming, the main thing is not to overdo it.

When hardened, the foam increases in volume so much that it can lift the window sill upward. To prevent such a nuisance, you need to put some kind of weight on the PVC plate. It is advisable to place something flat under the load so that the weight is distributed evenly. The load should be placed on the inner edge of the window sill, since the outer edge will already be securely pressed by the window block.

Checking deviations

We check once again whether there are any cracks, whether the window sill is installed evenly, Are the protrusions at the edges the same, are they observed? required slope. If small irregularities are detected during the first two hours after installation, they can be easily corrected. It may be necessary to make several gentle blows with a hammer in the desired direction, and the formation of holes or bumps can be leveled by moving the load on the surface of the window sill.

Sealing gaps

Gaps and cracks appear at the junction of the window slab and the slope, the window sill and the window, and the window and the slope. Obviously, it is advisable to correct such shortcomings after all the main elements (window, window sill and slope) have been installed.

The gaps are sealed using silicone sealant, which is applied in a thin strip at the joints. It is advisable to seal the edges of surfaces on which the sealant should not come into contact with masking tape in advance. Moreover, excess sealant and masking tape should be removed immediately after applying the sealant. Once it dries, this will be much more difficult to do and the result will be less neat. Excess dried foam under the window sill should be removed. The foam is easily cut with a stationery knife. The resulting cavity should be filled ordinary plaster for walls.

Excess foam under the window slab must be removed so that the thickness of the plaster layer is at least 1 cm. Such a layer will lie securely and will not be pressed through during further work and operation.

Installation of clamps

On final stage the side edges of the window sill are protected with end caps, and the window sill itself is cleaned of protective film.

How to wash a windowsill

When common home remedies such as: soap, soda, vinegar, tooth powder, chalk turned out to be powerless in the fight against pollution, special ones will come to the rescue chemicals. Choice of modern household chemicals will be able to cope with any contamination on plastic surface. You only need to correctly formulate your problem to the sales consultant in the household chemicals department, emphasizing that you need a product to clean plastic.

Careful operation and regular maintenance will help avoid problems associated with washing complex stains. The main thing is not to use metal scrapers and abrasives: they leave scratches in which dirt then accumulates.

It's up to you to install the window sill yourself or use the services of a specialized construction team. In fact, the process of installing a window sill is not complicated, but it requires the availability or acquisition of the necessary tools, Supplies(the remains of which may no longer be useful) and work skills. If the first attempt to install a PVC plate with your own hands is unsuccessful, then the total cost of self-installation may turn out to be much more than the wages of the master.
