Fast and correct plastering of window slopes. How is slope plastering done? How to approach the slopes of the mixture

When an old window is replaced with a new one, many people have difficulty finding a person who can qualitatively make slopes on windows using plaster.

Many people do poor quality work, they demand a lot of money. Due to improper installation of slopes on the windows, there will be heat loss, and extraneous noise will enter the house. In addition, the appearance of fungus, mold is possible. Therefore, it is important to know how do-it-yourself plastering of window slopes is done.

How to plaster slopes on windows: step by step instructions

To make the window opening of the apartment beautiful and complement the interior, you can use the work guide, which will be presented in the article. Before starting work, you need to remember the basic rules that allow you to make slopes on windows with high quality, they will not crack and will last a long time:

  1. The temperature in the room where the slope is made should be at least 5 degrees Celsius if cement mortar is used, and also from 10 degrees when using a rodband. All mixtures are prepared according to the instructions on the bags.
  2. All mixtures have restrictions on the period of use. As a rule, the time for using the finished solution is indicated on the pack. Cement plaster is used for half an hour, which means that it does not need to be cooked a lot.
  3. Before plastering windows, the number of mixtures should be calculated based on the thickness of the window openings and the size of the slope.

Knowing the basic rules for success, you need to know how to plaster the slopes on the windows from the outside, inside.

What tools and materials will be needed?


Masters recommend using not only a solution for window decoration, but also other types of finishing materials. For example, PVC panels or drywall. It is easier to work with such materials than with solutions, but the putty itself is cheaper, and it can be used on an internal or external slope.

The main thing during plastering is to be accurate and accurate, to put a little time and effort in order to achieve a positive result. The start of work will be from the choice of mortar, after which you need to find out how to plaster the slopes on the windows. The table shows the mixtures that are best to work inside and out:

Advice! When choosing a mixture for a window slope, one should take into account the time that this or that material dries. The cement base will take longer to dry, even in summer period. At the end of the work, finishing, finishing material is used. IN this case paint is used more often.

The plaster itself for slopes wooden windows, as well as plastic systems it will not cost much if you do not plaster with the most expensive mixtures. In addition to the material, you will need to prepare tools:

  1. Brush for priming walls.
  2. Paint roller.
  3. Grid.
  4. Spatulas of various shapes.
  5. Poluterok.
  6. Wooden element, lath.
  7. Level.
  8. Perforated corners.
  9. Lighthouses.

When choosing tools to finish the window opening, you need to take into account that the plane is small, so it is inconvenient to work with a large tool. It is recommended to buy additional gloves, for convenience, a table or a goat is used.

The use of gypsum and cement-sand mortars

Although puttying windows is old way, but all the same materials are used as before:

  1. Cement-sand mortar.
  2. Gypsum mortar.

In stores, you can easily buy one and the other material. The choice is up to the owner of the house. When using a gypsum mortar and comparing it with a cement mixture, the advantage of cement is in its cost, which will be lower than gypsum. When it turned out to close up the window, in any case putty is used, and after its application - painting, wallpapering. It is necessary to putty the window only after the plaster has completely dried, after about 6-10 days.


When using a solution of gypsum, the drying period is reduced to 3 days. In general, the drying time depends on the indoor temperature. After each stage of work, it is necessary to clean the surface from dirt and dust, and during the finishing of the window, all windows must be closed.

The disadvantage of plastering is the duration of the work, because at each stage it takes time to dry. Otherwise, the slope will crack, and the paint on it will peel off. Another disadvantage of internal and exterior finish slopes with solutions - cracks that appear after a short period of time. How to properly plaster the slopes on the windows will be presented in stages below.

Preparatory work

If there is a window sill, it is better to install it before plastering the slope, otherwise it will be necessary to beat off part of the slope from below and re-seal the flaws. Installing the window sill is simple, but before plastering the slope on the window, you need to seal it with tape and film or paper so that it does not get dirty or damaged. The preparation of the window slope is as follows:

  • A layer of old mortar is removed from the window, after which the walls are swept over with brooms so that the plaster adheres well to the surface. Otherwise, cracks will appear, even worse if the new layer just falls off the wall.
  • It is better to close the window frame itself with tape or tape.
  • Inside, it is better to paste over the fittings on the window, as well as the radiator under the window.

  • All surfaces to be treated are primed with a deep penetration agent. This allows you to achieve maximum adhesion of materials.
  • Further, the window is left for the soil to dry out, if necessary, insulation can be made. Insulate the window sill itself before installation and you can use the material for the slope. Insulation for the slope is not suitable for any, it is allowed to use polystyrene foam and expanded polystyrene.

Do-it-yourself plastering of window slopes

How to plaster slopes on windows? Initially, you will need to spray the walls with a primer to ensure good adhesion of materials. A liquid mortar is thrown onto the wall to ensure better adhesion of the further mixture. This procedure is done over the entire surface, which will give a positive result. An excellent method is suitable if the layer of putties is thick. Next, you need to plaster the window opening like this:

  • It is necessary to install rails made of wood or metal, beacons that are sold in any store. They are mounted on mortar, but this does not guarantee strength, so you can use self-tapping screws or dowels if the house is brick. Correctly installed rails serve as a guide for installation.

  • Lighthouses are mounted on a plumb line so that they do not move, due to this the slope will be good, even.
  • The main beacons have been installed, now you need to make special beacons that will allow you to level the surface of the window slope and shape the edges.
  • The device is made easily. From an even tree, 10-15 centimeters longer than the slope, a nail is nailed on the reverse side, and it is better to bite off the hat with wire cutters so that the external or internal slope is not scratched. The nail is driven in at a distance of 4-7 mm from the rail.

  • Further, a ready-made mortar is placed in the slopes, and you can level the layer with a small one, moving the bar from the bottom up, to bring the surface into an even state. The rest of the solution is removed, the slope is left to dry. So you can plaster the slope of the window in one layer, but the work does not end there.
  • While the plaster composition is not completely dry, it is overwritten. Work is carried out from the top point to the bottom, with the help of translational movements.
  • After drying the solution, the slats are removed, you need to close up the holes that came from the slats with a small amount of material. After that, the window slope is grouted again.

  • Next, you need to bring the surface into a perfectly even state, for this you need to properly plaster the walls using a special spatula. The solution is applied in several layers, each of which is rubbed. During the application of the first layer, it will be correct to install a plastic perforated corner around the perimeter of the window so that the slope has the correct shape.
  • Next, the window slope is painted in several layers.

During operation, while the solution has not yet dried out to the end, it is necessary to make a furrow between the window and the slopes with a spatula, the width and thickness should not be more than 5 mm. Next, a sealant or liquid plastic is used to fill the void. This move is necessary for a plastic window, because from high temperatures they expand and increase in volume, therefore, cracks and breaks often appear in places of slopes, even if it was possible to plaster perfectly. The sealant will not allow the slope to deform.

At the end, around the perimeter of the window, you can stick decorative corner, which will add beauty, and for the summer you can close the window with foil so that heat does not enter the house or apartment. It is necessary to insulate so that the window does not freeze in winter, the warmth does not leave the house. You can choose the design of the window from the photo on the Internet, and you can get acquainted with the work, the solution and the technique of doing it yourself in detail on the video:

The slope is one of the main elements of the window or doorway. Without side surfaces, the entire structure can hardly be called complete. Firstly, incompleteness always looks unattractive, and secondly, slopes are additional protection against heat loss, which is very important for complex facade insulation.

You can save on energy consumption, and if you choose a budget material, the benefit will be significant. - the cheapest way to finish. All work can be done independently, for this you will need plastering material, tools and basic skills.

It is unfair to consider the method of plastering slopes hopelessly outdated. Modern technologies greatly facilitate Finishing work and allow home craftsmen to do everything on their own. Difficulties when working with plaster mixtures are extremely rare.

This is a classic, one of the familiar materials that is easy to work with. If you follow the technology, you can not worry about the result. Plastered surfaces are durable, moisture resistant and environmentally friendly.

External slopes are made in different ways. In addition to plaster for external decoration and insulation, they use:

  • metal;
  • drywall;
  • wood;
  • lime;
  • PVC panels;
  • stone.

These are the most popular materials, each of them has its own advantages and disadvantages. Stucco slopes are chosen by those who value durability and visual appeal. This material has stood the test of time and is associated with reliability. Plus, in affordability, the cost of arrangement will be minimal.

With proper implementation installation work seams will remain invisible. The plaster mortar fills all cracks and crevices, which ensures the integrity of the structure, high-quality sound absorption and waterproofing. This material is resistant to mechanical stress, easy to repair and update. It can be painted, varnished, decorated with decorated elements.

How to choose a plaster and prepare the right solution?

A mixture for plastering slopes can be bought. Facade plaster is better suited for outdoor work. Following the instructions, dry mixtures are diluted and applied to surfaces. Despite the inconvenience and efficiency of preparing ready-made solutions, many people prefer to make mixtures on their own. Their quality depends on the observance of proportions and the choice of the desired material.

Frost-resistant and moisture-resistant are suitable for external finishing of slopes, the best option is a cement-sand mortar. It is cement that is the most durable among the binding materials for external slopes. The component composition provides excellent adhesion to the base. The integrity of the coating is maintained much longer than with other mixtures. Building gypsum and clay are inferior in many respects. They are sensitive to moisture, which can lead to the destruction of the coating.

Cement is diluted with water. The most commonly used filler is sand. The standard proportion is 1:3, the consistency of "liquid sour cream" is considered ideal. Too thick a mixture can cause cracking of the surface, and a weak aqueous solution will spread.

The cement-sand mixture sets in 15 minutes, hardens in 11-12 hours. If you do the plastering of slopes with your own hands and there is no experience in this matter, it is better to prepare the solution in small portions. The application process requires promptness, you can simply not cope, as a result, the material will harden and be unusable.

Ideally, on a well-finished slope, defects do not appear. The plaster should not flake off, crumble, crack, etc. If these phenomena are observed, additional costs for restoration and sealing will be required. In order to prevent marriage in work, we first advise you to study the instructions for using the material or consult with professionals.

External slope plastering technology

The arrangement of slopes is a laborious process. It will take patience, accuracy and care. As you take on the job yourself, consider three key points proper plastering: high-quality mortar, competent application technology and professional grouting. Algorithm for finishing window and doorways in many ways similar, all plastering work can be done in 3 stages:

Leveling and cleaning surfaces

The bases must be clean. To do this, eliminate all contamination and external defects: protruding mounting foam, residues old plaster and paint, greasy stains. Cracks are carefully cleaned. If this is not done, the new layer will simply fall off.

The original surface should not have lagging parts and irregularities. In order to avoid deviations, it is checked for a vertical. With minor irregularities and the presence of voids, a leveling plaster layer is applied. For large deviations, a wire mesh can be used.

Application of the mixture

The plaster layer should not exceed 7 mm. Each next one is applied only when the previous one dries up. This is one of the main rules for plastering slopes. There are other nuances. The desired thickness is marked with a pencil and. They serve as a guide and allow you to achieve maximum evenness.

To improve adhesion, before starting work, the solution is made more liquid and distributed over the surface. Do this by throwing on a plane with a spatula. The solution should stick immediately and not spread. You can correct the surface small.

Finishing

After the solution dries, the corners are corrected, the slopes themselves are overwritten and treated with a primer. The final design depends on preferences. This can be painting, tiling, varnishing, etc. The main thing at this stage is to wait for the solution to dry completely.

In this chain of actions, it is important to follow the sequence. This is the only way to achieve a good result and enjoy the work done. Plastering slopes will not take much time, and with a competent approach, it will transform the facade and protect it from bad weather. Moreover, all this with minimal costs and labor costs.

Plastering slopes after the final installation of plastic windows gives an aesthetic appearance. The final work can be done independently or with the help of specialists.

It's no secret that there are other ways to finish. For example, the use of panels made of drywall, wood, plastic. Plastering window slopes has several advantages:

  • Long time use.
  • Low material cost.
  • Ease of execution, you just need to choose the right way to plaster the slopes.
  • Stability, strength.
  • Good thermal insulation.
  • Hiding mounting parts if necessary.

Plastering of slopes of both plastic windows and wooden ones is possible.

Tools and materials

For convenient and accurate work, we will need:

How to make a mortar for plastering

Depending on the humidity of the room and the installation of the considered part of the window opening - internal or external, they choose how to plaster it. You also need to take into account that we live in a strip where the main season is winter, which means that the composition should be frost-resistant.

In an apartment with high humidity for external slopes, it is better to choose a composition with cement. Please note that it has water-repellent and heat-insulating effects.

Gypsum or lime-gypsum mixtures are suitable inside the house.

In both cases, you can use acrylic material, but keep in mind that it is not cheap.

The mixture is bought or made by yourself.

If you decide to use the latter method, remember that incorrectly calculated proportions will lead to poor results: a composition with a high fat content (a high amount of binder material) may begin to crack after drying. Insufficient fat content will make the mixture fragile, plaster window slopes such a composition will turn out to be a futile exercise, soon you will have to do all the work again. Do not prepare a lot of solution at once. If you do not have time to use it within an hour, it will harden. When choosing a solution, you need to take into account that the gypsum mixture dries much faster than cement.

Properly mixed plaster will stick to the blade a little.

Surface preparation

First you need to close the window block. This is best done with construction tape, and cover the window sill with a film. The surface of the side opening of PVC windows must be cleaned, then
align. Previous layers of plaster will also need to be removed. The old mixture will fall off if tapped on both sides. At the same time, it is convenient to help yourself with a construction knife.

Brick walls are treated with a solution of hydrochloric acid, and then washed with water. If there are oil stains, you need to apply oily clay on them, let it dry, rinse with water.

For better adhesion of the composition to the surface, it is better to use a deep penetration primer. Then install beacons so that the job is done smoothly. Visual perception will not help here. Finishing slopes with plaster is carried out strictly along the guides. The primer should dry well.

Slope insulation and soundproofing

Following right technology do-it-yourself plasters for plastic windows, you can significantly improve the thermal insulation in the apartment. To do it well, you need to remember:

from inside the room it will be correct to use more airtight, dense materials, and closer to the outside - heat-insulating, porous.

This creates ventilation of the insulation, which avoids condensation.

The quality of sound insulation depends not only on the design of the double-glazed window - the type of window seals and sealant is also important. Sound absorption will be higher with more elastic materials.

There is currently on the market big choice heaters, ranging from polyurethane foam and ending with foamed polyethylene.

How to plaster slopes on windows?

It is necessary to start plastering the slopes on the windows indoors, and first of all they do the right and left sides, and then the bottom and top of the surface.


Do-it-yourself plastering of the outer slopes of windows takes place using a similar technology. After working with a plastic window, a groove is made between the frame and the leveled surface with a spatula. Then fill it with sealant so that there are no cracks.

By following these simple rules, you can get the job done quickly and efficiently.

Understanding how to plaster slopes is easy. However, this work requires maximum responsibility and a competent approach. You will be able to correctly plaster the slopes of the window only after a detailed study of the basics of plastering other, more simple surfaces(for example, ceiling and walls). Therefore, it is advisable to pre-train, and only then plaster the slopes of the windows. A few simple and intelligible, but very useful recommendations will help you do this in the best possible way.

Preparation of tools and materials for work

Any repair work require the use of appropriate tools and materials. And is no exception. The specific set of tools depends on what materials you will be doing the work with. However, without the following devices, you will not be able to do in any situation.

Plastering window and door slopes with bevels: 1 - wall; 2 - solution; 3 - rail; 4 - the position of the bevel when plastering the slope; 5 - box; 6 - small.

Prepare:

  • aluminum rule;
  • building level;
  • measuring tape and pencil;
  • Malka;
  • several spatulas (must be 5 cm);
  • containers for water and solution;
  • Master OK;
  • hammer-pick.

It is not enough to just know the list of tools. In order to properly plaster the window slopes, it is necessary to use the most suitable fixtures for this particular process. For example, too long level in this work you will not help. It may not fit in the space between the window sill and the lintel and become completely useless. However, even using an overly short tool, plastering the window slopes will not work - it will be very inconvenient. Therefore, the best option is a level 100 cm long. Auxiliary tools such as a knife and a sealant gun will not interfere.

When working, you may need a bottle of mounting foam. Carefully examine the condition of the window before going to the store. If there is a gap between the window opening and the frame, then the balloon will be needed.

If you use ready-made cement mortar for plastering, you will additionally need a trowel and a grater. If you use other solutions, then prepare trowels of different sizes, a sponge grater and a medium spatula. In most cases, a spatula of 45 cm is sufficient.

Prepare good protective clothing and footwear. They should be comfortable for you. Be sure to choose a suitable headgear so that the plaster does not fall on your head when processing the window slope. Due to the fact that in the process of working with plaster you will have to contact with your hands, it is best to buy sealed nitrile gloves.

A plaster goat will be a very good helper. You can make it yourself, buy it or borrow it from someone. It is more convenient and safer to work with it. Plastering a window slope from a stool or stairs is not best idea. Firstly, it is less safe, secondly, it takes longer, and thirdly, it is not very convenient.

Preparing for processing window slopes

Before the plastering of the window will begin directly, you will need to perform a number of preparatory measures. Not only the convenience of further work, but also the quality and durability of the finish directly depend on how thoroughly and carefully you approach the preparatory process.

Before work, it is recommended to install a window sill. So you will avoid further work on sealing the gaps between the window sill and the side slopes, and further increase the strength of the installation. In such a situation, the window sill will need to be protected from mortar and mechanical damage. To do this, cover it with thick paper. If after the repair you have unnecessary pieces of drywall, use them - it's even better.

If there are traces of old plaster and other unnecessary dirt on the window, be sure to remove them. A high-quality finish will be obtained only when laying plaster on a solid and well-prepared surface. Any dirt, dust, paint, etc. significantly worsen the final result.

The window block itself is recommended to be carefully closed with a film. It will be enough to stick it to the window with masking tape. Batteries, pens and other items that may “suffer” from plaster during operation, wrap with thick paper.

Cross-section of a wall with high-quality plaster: 1 - spray; 2 - soil; 3 - covering; 4 - brick wall.

Remove excess mounting foam with a knife if you used it to seal gaps. To improve the setting of the plaster mortar with the base, it is necessary to pre-treat the surface with a deep primer. When choosing a specific primer in the store, be sure to inform the consultant about what the base is made of.

In the next step, you will need to work on the vapor barrier device. For this inner wall covered with vapor barrier film. It can be sealed with foam or treated with a special frost-resistant silicone sealant. Make sure the surface is dry before applying the sealant. Otherwise, the composition will not stick. Remove excess sealant immediately. The solidified substance is very difficult to wash off.

If you do not vaporize the foam seal from the inside, then after some time the foam will get wet under the influence of condensate and lose its original properties as a heater. In some cases, it may completely collapse. As a result, the windows will begin to sweat, and drafts will be pulled from the street.

In the next step, you need to make a Malka. It is a template according to which you will plaster. Look at the slopes of your window. You will notice that they do not have a perfectly straight shape, but rather expand inwards. As a result of this, in fact, a window clearance is formed. In most cases, a piece of plywood is used to make malki. It should be 5-10 cm longer than the window slope. The width will be about 15 cm enough to make the template comfortable to hold with your hand during work. A cutout is made on 1 side of the bevel. During the plastering process, the side with the cutout will move along the slope. On the 2nd side, you will move along a pre-installed beacon. Malka will provide the most even windows. Additionally, it is necessary to make a cutout for window hinges.

Approach the manufacture of the template as responsibly as possible. Keep work surfaces as level as possible. If possible, remove a small chamfer (round the surfaces with a file). This will prevent chips from appearing on the plywood during operation.

Professional craftsmen use aluminum bevels for work. They are made to order. However, if you do not plan to professionally plaster slopes, it is quite possible to get by with an ordinary wooden template.

Plastering of window slopes dates back to the time when windows in their modern appearance became familiar to mankind. The technology of this type of work is so elementary that even an unprepared beginner can easily cope with it. Moreover, there are now much more plastic windows than wooden ones, and the plastering of slopes on such windows is even easier.

Selection of tools

How to plaster slopes and what tools to use for this, each master considers differently.

For indoor work, do not use a level that is too large or too small, a meter is best. Also stock up on sealant and a knife.

Before plastering the slopes on the windows, check whether all gaps are filled with foam, you may need to eliminate imperfections on the part of the installers.

If you decide to do the plastering of slopes with a cement solution, get a grater and a trowel, and for working with Rotband you will need different sizes of trowels, a wide spatula and a sponge grater.

Preparatory work

High-quality plastering of slopes with your own hands is impossible without following the following preparatory procedures:

  1. remove excess mounting foam with a knife;
  2. clean the surfaces with a brush with metal bristles;
  3. remove dirt and construction debris;
  4. start priming work (inside a dry room, you can use a liquid cement mortar or antibacterial substances);
  5. around the perimeter window frame to the base of the wall, it is necessary to apply a sealant that will increase waterproofing (for such work, substances are used that contain silicone, with its help the windows will not sweat, working with it is simple and comfortable, it is inexpensive and brings a lot of usefulness).

What solutions are used for plaster slopes?

It is necessary to plaster the slopes both indoors and outdoors. For work inside the room, you can use a combination of sand and alabaster in a ratio of 1: 2. A solution based on cement and sand is kneaded 1: 3, and a mixture of cement, alabaster and sand - 1: 1: 2.

Plastering slopes with your own hands becomes easier to perform thanks to the use of the Rotband dry mix. The cost of such material, of course, is not small, but it lays down evenly and has warming and antibacterial properties.

For finishing slopes from the outside, you can only use cement mortars: they are not afraid of changes in air temperature, different humidity and chemicals. Most importantly, do not forget to mix liquid glass and a plasticizer into this mixture.

The process of plastering slopes

Before proceeding with the installation of beacons, calculate at what slope the surface will be installed. Experienced builders call this indicator "dawn angle", and set it with a goniometer. Do not be too self-confident in your eye, the result of installing the surface “by eye” will not be very pleasant and will require rework.

Now you can start installing beacons. From the outside, you can use a flat plank made of wood or a metal profile, and near the frame you can not do without an aluminum corner. The external beacon, after completion of all work, can be removed, and the internal ones will be covered with plaster.

The outer beacon is fixed on the surface with nails or self-tapping screws, and the inner beacon is planted on alabaster or cement until it dries completely.

If you need to cover an area with a thick layer of mortar, give each one time to set. The maximum allowable density of pouring mortar from cement and sand should not exceed 2 cm, with gypsum mortar - 5 cm.

If you decide to plaster newly installed plastic windows and noticed them protective film, do not rush to remove it until the slopes are ready. Such work is usually very dusty, and the film will help protect the frame from damage and dirt.

But, if you still removed the protection, stick masking tape or polyethylene on the window.

Do not rush to apply one layer of mass to the second, give each of them time to dry - this will allow you to protect the walls from cracking.

The density of the extreme tier should cover the beacons. After throwing the mortar, all excess mass can be removed with a spatula or plaster corner. As a result of such actions, you can get a flat and smooth surface.

At the next stage, you can start grouting the slopes with sandpaper and making them smooth.

After that, you need to remove the corners. To do this, you will need to remove all external beacons and use a grater and trowel. The trowel should be leaned against one surface, and the grater should continue to apply the mixture and level the corner. After that, the same work is carried out on the other side.

The next step is painting. For this it is better to buy acrylic paint water based. If your apartment is dry and warm, you can not treat the slope before painting with a primer. But, sometimes (especially in rooms with high humidity), it is still worth covering the surface with an antibacterial primer solution.

Pay special attention to the fact that plastic can be exposed to the sun and expand. So that because of this the frame does not crack and deformation does not occur, use this advice: when you finally level the plaster, cut a notch 3-5 mm deep with a metal spatula, and then fill it with a colored sealant (to match the lining) based on silicone. Due to its elasticity, silicone will protect the structure from possible deformation.

In conclusion, I would like to say that it is quite possible to plaster the slopes on your own, having a certain amount of knowledge. But, if you have never held in your hands Building tools, let experienced and knowledgeable people solve the problem “how to plaster slopes”.
