Plastering of window slopes as a way of decoration and reliable protection. How to plaster the slopes on the window correctly? How to make plaster window slopes

How to plaster the slopes on the windows? A similar question arises for many people who decided to independently seal up the transitions formed when replacing windows. One of the best solutions for finishing slopes is the use of drywall, with which you can quickly and easily create a perfectly flat plane. In addition, it is necessary to plaster it only in exceptional cases, since most often to achieve the desired effect.

Plastering the window slope

The purpose of the plaster is to seal cracks and holes, as well as to correct irregularities in the walls and ceiling. Most often, it is used when working with concrete and brick surfaces, which, due to the complexity of installation, simply cannot be made even. Plastering makes it possible to eliminate obvious flaws in the plane and completely level it. However, such a surface is not suitable for applying a decorative coating, since it requires finishing.

Most of the plaster mortars are made on a cement or gypsum base. At the same time, unlike putty, plaster is distinguished by a large grain, which affects the quality of the finished surface.

Plasterboard slope plaster

In relation to plaster, they are used extremely rarely, since their surface is already flat. Therefore, from the inside, they are never covered with a layer of plaster.

The only option when it is necessary to plaster window slopes made of plasterboard is their location on the street or in places with high humidity, such as a kitchen or bathroom.

In such conditions, the purpose of plastering is not to level the plane, but to protect it from the negative influence of moisture particles that can lead to damage to the material. At the same time, it is necessary to plaster the slopes on plastic windows or doors correctly, without violating technology or neglecting building codes. The process of plastering window or doorways consists of two equivalent parts:

Each of these stages contains its own characteristics and specific structure. Depending on the location of the slopes, the main stages also change. construction works... Their purpose in a bathroom or kitchen is to protect the plasterboard surface from steam particles, and outside the room is to counteract the direct influence of atmospheric precipitation.

Preparatory work: main points and their characteristics

How to plaster the slopes on the windows inside and outside? The purpose of the preparatory work for the processing of window and door slopes is to create optimal conditions for applying the next layer of finishing and improve the waterproofing characteristics of the surface. It consists of the following stages:

How to properly plaster the slopes on the windows? Preparatory work is a mandatory stage of construction work, which allows you to create optimal conditions for plastering on slopes front door or windows.

Important! Slopes between a window or door can be closed with special plastic inserts. Their installation is carried out using fastening systems and does not involve any "wet" processes. In addition, the plastic pads provide good moisture protection and have excellent appearance.

Plastering door and window slopes: a step-by-step sequence of actions

How to plaster the slopes of doors and windows? Leveling the plane, eliminating its defects and creating a waterproofing layer is carried out according to a certain procedure, which includes the following stages:

Ready-made, which ensures a flat and monolithic plane. For working with external slopes the best solution is a plastic cladding. It is she who makes it possible to completely protect the surface of the drywall from moisture and preserve its integrity. See in the video: DIY plastering of door slopes.

Conclusion

Plaster of plasterboard slopes does not belong to the category of mandatory stages of construction work. The purpose of this process is to increase the bearing characteristics of the surface and protect it from moisture, which is especially important when processing external input or window slopes... It consists of two main stages of preparation and direct application of the solution. Moreover, after the plane dries, it must finishing, which can be puttying or installation of plastic panels.

The question of how to plaster the slopes on the windows , can occur in two cases: the slopes were once made, but they need repair, or they are not at all. At the same time, it does not matter when the windows were installed and what material they are of, often builders do not want to deal with this issue, and the owners themselves are forced to plaster the slopes. This procedure is simple, and anyone can learn it.

What are slopes used for?

These elements are necessary not only from the inside, but also from the outside of the window. They perform the following functions:

• Decorative: they make the window complete, they can decorate it, help give a certain stylistic direction
• With the help of finishing slopes, you can hide installation elements, traces of foam and other construction activities.

Plastering helps to get rid of excess moisture on the glass, make the room warmer, eliminate drafts, and increase the level of silence.

Prepared slopes for plaster

What is required for the job?

You can finish the slopes yourself without much experience, for this you just need to read the instructions and purchase the necessary tools, which include:

• Building level.

Advice : It is best to use a long tool, which will allow you to know for sure if a bevel has occurred over a large section.

• Rule (aluminum is most often used).
• Roulette.
• The container in which the solution will be stirred, water or a primer will be collected.
• Convenient size spatula.
• Master OK.
• Cement grater.
• Sealant in the gun.
• Profiles and planks.
• Small auxiliary tools such as a knife, pencil, brushes for applying a primer.

Advice: before plastering the slopes on windows with inside, equip the goats. Using a stepladder is inconvenient, you can fall over or drop the bucket.

How to make a plastering solution?

It is diluted with water, so its consistency can be different and depend on how much liquid was added to the mixture. The composition of the substance itself may also differ. Ideally, the mixture should look like semolina... For areas where the humidity is high or outdoors, it is better to use a compound containing cement.

Ready dry mixes for plastering

It is not difficult to decide the slopes on the windows inside, since in most stores you can find a ready-made mixture for this purpose, but the substances differ somewhat in composition. A cement variety is required for outdoor work. If the work will be carried out indoors, you can use a gypsum mixture: it is convenient to use, quickly solidifies, and has an optimal consumption.

Before starting the surface, you need to close all the cracks; this can be done with construction foam. It is also required to cover the surface with a primer.

Advice: it is better to work in a headdress, as, falling from a height, the plaster can get on the hair and harden. It will be difficult to get rid of it.

Preparation of mortar for plastering

The order of work

Plastering window and it is required to start with the preparation of the area for this. First, the window opening cleans, removes dirt, dust, degreases the surface and fills the voids with polyurethane foam. When the foam hardens, you can cut off the excess. Do not worry about its appearance, the plaster will still cover the mounting material.

In order to prevent moisture from getting into the joints, they need to be sealed with a special tape, which you can buy at any hardware store. The window sill is mounted before plastering work begins. This will allow you to immediately seal the cracks with polyurethane foam and give the structure additional strength.

Advice: if the window is already ready for use, a battery is installed under it, a window sill is mounted, there are fittings, it is best to cover all these elements with a film, otherwise the plaster can stain them, getting and drying to the surfaces during the work.

Plastering of slopes is carried out after the elements of the slope are impregnated with a primer. It is needed so that the plaster fits better on the wall surface. The primer is chosen depending on the material of the walls. There are different types of it, designed for wood, concrete, and other materials. Do not start work before the primer is completely dry. At room temperature, this happens for about a day.

Once the gaps have been repaired, it is too early to think about plastering. A vapor barrier is required. It looks like a film, but you can also use a sealant. The task of this layer is to protect the plaster from moisture. If we neglect this stage of work, the slopes may deteriorate after a while, condensation will begin to appear on them, fungus is possible, the plaster will begin to soak and crumble. In addition, the film will help to avoid drafts.

Advice: must be frost-resistant. The usual one, which is used indoors, will lose its properties in winter and collapse.

Excess material should be removed immediately after application of the substance, it is most convenient to do this with a wet sponge.

Plastering slopes after installing the head profiles

Work process

You need to work with the composition at a positive temperature, if the composition is at least +5 degrees, cement - +10. Each solution has certain requirements, the manufacturer provides them on the packaging, the proportions must be observed as indicated in the instructions.

Preparing slopes for painting

Plastering door slopes begins with the installation of corner profiles. They will be required to protect the slope from mechanical damage, and also provide orientation along the lighthouses. After that, the guides are installed and the solution can be applied. In order for the slope to turn out to be even, you will need to set its corners and work according to the level.

Advice: the plaster is applied in three layers. Before applying the second, the first one should dry thoroughly: it will take about a day, so you should not think that the work will take little time.

After the last coat is dry, it can be cleaned with sandpaper and primed to paint.

Output: how to plaster the slopes , it is not difficult to learn, you can learn this skill almost immediately. However, you need to immediately prepare for the fact that this process will take a lot of time.

Plastering is the most budget option arrangement of window slopes. This is not a difficult job, but, despite the extreme simplicity of implementation, you also need to prepare for it.

In the absence of experience in conducting such events, it is recommended to begin with practicing plastering simpler surfaces such as the ceiling and walls. Having mastered the basic subtleties of the process, you can independently plaster window slopes no worse than a qualified master.

Before starting work, prepare all the accessories necessary for its implementation. It is better to collect all the required elements in advance so as not to be distracted by the search for missing elements in the future.

You will need:

When choosing a building level, pay attention to the length of the product - the tool should fit normally between the window sill and the lintel. At the same time, the level should not be too short either - it is simply inconvenient to work with such a tool. The optimal level is 100 cm.

Additionally, you may need various assistive devices, such as:

Before proceeding with finishing works, you have to perform several preparatory activities... Pay due attention to their implementation. The convenience and speed of further finishing and, in general, the quality of the finished coating directly depend on the correct preparation.

It is better if the window sill is installed before finishing. Otherwise, in the future you will have to close up the gaps that appear between the side window slopes and the mounted window sill.

First step... Provide reliable protection of the window sill from damage and contamination with mortar. For protection, it will be enough to cover the product with a simple thick cardboard or with suitable drywall scraps, if available.

Second step. Remove old plaster, paintwork and any kind of contamination from the surfaces of the opening, if present. The wall for laying the plaster must be clean and even, the presence of dust and any other contamination is unacceptable.

Third step. Cover the glass unit with plastic wrap. You just need to glue protective film to the double-glazed window with scotch tape.

Pens, heating batteries and also wrap all the rest of the accessories with foil or thick paper.

Fourth step. If you find excess foam (it is assumed that all slots have already been blown out with this material after installing the window), carefully cut them off with a sharp knife.

Fifth step. Cover the surfaces of the opening with a deep penetrating primer. Such treatment will contribute to the improvement of adhesion (setting of the applied plaster mortar with the finished surface).

When choosing a plaster, be guided, first of all, by the material for making the window opening. A specialist store consultant will help you choose the right mixture.

Sixth step. Equip a vapor barrier. To do this, cover the foam seal with a special film vapor barrier material, or cover it with a frost-resistant silicone sealant.

Apply the sealant to the previously cleaned and dried surface. Dispose of excess sealant immediately. It is very difficult to remove the cured product.

Without the internal vapor barrier of the foam seal, the foam will constantly get wet from the resulting condensate, lose its thermal insulation properties and collapse. In parallel with the foam, glasses and slopes will begin to get wet, a draft will appear in the room, etc.

Seventh step. Make a mala. You can buy it ready-made, but making it yourself will save you a certain amount of money.

Malka is an ordinary template used for plastering. Examine the window slopes. You will notice that they do not have a strictly even shape, but seem to expand slightly inward, due to which the window dawn is created. In order to qualitatively plaster such a surface, a bevel is needed.

Video - Using Malka

For self-made the easiest way is to use sheet plywood. Ready template will have a width of about 150 mm, and a length of 50-100 mm more than the length of the slope. A cut must be made on one side of the template. You will move the side with the cutout along the window slope, and the other side along the pre-assembled lighthouse.

As a result, the finished surface will be as flat as possible. Also, in the template, you need to make an additional cutout to pass the window hinges.

The manufacture of malka should be taken with full responsibility. The working surfaces of the template should be as smooth as possible.

Professional painters-plasters use aluminum beads in their work. Such devices are usually made according to individual order, but ready-made options can also be found in specialized stores... In this moment, make a decision at your discretion.

Of course, the slopes can be plastered without a template, but in such a situation the angles are unlikely to be the same.

What do you need to know before getting started?

To make the work as easy as possible, and the finished coating is durable, beautiful and of high quality, remember and follow these simple rules:

The procedure for plastering slopes

The process of finishing the slopes with plaster does not differ significantly from the plaster of simple walls with an angle. However, as already noted, when finishing window slopes, it is strongly recommended to use a bevel.

First step. Determine the location of the slope angle.

Second step. Set the rule with a level at a certain angle and mark the position of the angle on the surface of the wall with a pencil.

Third step. Apply starter plaster to the surface to be finished. The bottom layer of plaster must be thick enough.

Fourth step. Press the template against the sash and slowly smooth the plaster off the slope. Your task is to get the correct angle and smooth surface slope without irregularities.

Fifth step. Remove the rule by slowly moving the tool along the slope.

Sixth step. After the bottom layer has dried, apply a finishing plaster mixture to the slopes. Pre-place special products called perforated corner on the corners of the slopes. Such elements should be fixed in a not yet dried starting layer of plaster, slightly pressing them into the coating. Thanks to these devices, additional protection of the edge from various kinds of damage will be provided.

After a while, use the ironer

Apply the finishing coat in the same order as the starting coat. Make the second layer thinner than the first.

Level the plaster until the finish is as smooth and perfectly smooth as possible.

In the case of finishing slopes plastic windows ny structures, a number of separate rules must be observed.

The work is carried out in the sequence described above. After the design of the slope in the not yet dried plaster mortar, a small groove must be cut with a spatula. Make it between the frame of your window and the slope itself. A depression up to 0.5 cm wide will suffice. The finished cavity should be filled with silicone sealant.

PVC (the main material for the manufacture of the windows in question), especially if it is of low quality, expands noticeably when heated. In the heat, the plastic can expand so that cracks form at the junction points of the block with the slopes. The silicone sealant has an elastic structure and will not allow the above problem to appear.

Now you know how to cope with plastering slopes on your own. Follow the recommendations received and everything will definitely work out.

Happy work!

The final finishing of the slopes after the installation of plastic windows is a mandatory step in decorating a home. In addition to decoration, well-made slopes insulate the window frame well and protect the room from dust, drafts, rain and snow. Correctly installed windows will serve you for a very long time.

It is customary to make slopes immediately after installing windows. The mounting foam, with which the gaps between the window frame were blown out, collapses literally in one season when moisture and direct sunlight hit it. It alone cannot provide sufficient insulation from moisture and cold, and even more so, if it is destroyed. So the seams from polyurethane foam must be carefully hidden under the slopes.

The use of cement or other special mortar for finishing and decorating slopes is the cheapest among analogues - finishing with metal, plastic, ceramic tiles, drywall, etc. The downside of these works is that they are very dirty, an inexperienced or novice builder will have to tinker before the slopes become perfectly smooth. Therefore, if you are not confident in your abilities, we recommend that you turn to professionals who will do this work much faster and better. However, if you decide to try to make them yourself, then you need to study the types of plaster that are used for these purposes, the necessary tools and the technology itself, which should be unswervingly followed to achieve the highest quality result.

Types of plaster

To get the maximum benefit from the upgrading of newly installed plastic windows in terms of heating and to achieve maximum comfort, you should first of all look at special heat and sound insulating plaster. It has high reflective properties due to the use of natural raw materials as components - vermiculite, perlite and their mixture with durable gypsum.

The scheme for preparing a solution for plaster is quite simple - you need to buy one of the above building mixtures and dilute it with water, smoothly and thoroughly mixing. The consistency of the finished solution should not be very liquid, otherwise the plaster will start flowing right on the slopes, but it should not be too thick and stretchy - it will be very difficult to work with such a solution, and it will set too quickly.

Mixed bags usually indicate the optimal mixing ratio for the preparation of the solution, so we advise you to follow the manufacturer's recommendations. It will also indicate on what area this amount of the mixture will be calculated for a given preparation of the solution, therefore, having previously found out the approximate area of ​​work (with a small margin), you can calculate how much of the mixture you need to purchase.

Preparation for work and collection of tools

Tools and materials that you will need in the process of carrying out the work:

• construction trowel;
• marker;
• drill and construction mixer;
• sharp knife;
• construction brush;
• container for water and solution;
• plumb line;
• square;
• metal and rubber spatulas of different sizes;
• plaster mix;
• water;
• painting, plastering or metal grid and fastening materials to it (staples, screws, dowels, the solution itself will do).

Preparation for work consists in collecting necessary tools and the actual preparation of the surface for work. It consists in cleaning the protruding excess of polyurethane foam with a sharp knife. It is advisable to cut off the foam at a level with the window frame; you should not go deeper into the seam. Using a brush, remove as much as possible all dust and dirt from the surface where you will be working. After completing the preparatory work, we proceed directly to the main part of the work.

Plastering of external slopes of plastic windows

This procedure consists of several stages:

• The most difficult stage in finishing work is the plastering of the upper part. From it, we begin to attach the base for the applied solution - the type of mesh you have chosen. The shape of the attachment depends on the type of slopes that you will make - straight (perpendicular to the window frame) or unfolded.
• Strictly by the plumb line, we determine the thickness of the layer that we will apply, and mark the value with a marker.
• The surface on which we will apply the plaster must be very well treated with a construction primer, this will allow the mortar to adhere more firmly to the surface.
• After that, we knead the plaster solution for the first time. To create the best quality mortar, it is recommended to use a drill with a construction mixer. It will ensure thorough mixing of the components and uniformity of the structure.
• With the help of a trowel and a spatula, we apply the first rough layer, trying as carefully as possible to fill in all the flaws in the surface of the walls. The installed mesh will serve as additional reinforcement and will not allow the plaster to peel off, but to set right on the wall.
• If you need to fix a lot, and the layer is very thick, then you should not immediately apply it completely. It is better to do it in stages, to put on the necessary layer several times, each previous layer is pre-primed. Each of them should be allowed to dry for at least 1-2 days.
• The last layer must be removed with a spatula, forming a finishing surface. Usually, after drying, small cracks remain on it, they are caused by the fact that "starter" mixtures are used for the plaster. To remove them, you need to use a small (for the size of the slope or a little less) with a spatula to process the dried slope with a slightly more liquid solution than was previously used. By applying a moderately thin layer, under it we will hide all the imperfections of the rough surface. After the last layer has dried, the surface is carefully sanded, while removing small undulating irregularities.
• After they are formed, you need to bring out the corner with the main wall. For this, two floats are used, one of them is placed against the plane of the main wall of the building, and the second one is used to create a slope with a beautiful even angle. It is recommended to first mark the angle line using a plumb line so that it does not turn out to be overwhelmed. For this, the plaster solution needs to be moderately thick, so that the required angle can be freely formed, and after the trowel, the applied layer did not immediately float, but began to set.
• After the formation of the corner is completed, you need to wait until the applied solution is completely dry. To do this, you need to wait at least 2-3 days in dry weather, so that you can fearlessly begin to further refine the slopes.
• Next, gently but thoroughly rub off the last layer of the applied plaster. Visible cracks and minor imperfections are easily corrected by soft paint brush and a liquid solution. Such a layer does not take long to dry, and soon you can start priming the slopes.
• The next mandatory step is to protect the plaster from moisture. The ideal option for this would be to use a hydrophobic paint from the same manufacturer whose plaster mix you used. This layer will protect your plaster from water and will not allow external natural phenomena to adversely affect it.
• After protection from moisture, ready-made smooth slopes can be painted with facade white paint. The recommended but more expensive option is to use an acrylic sealant, which will add another protective layer in addition to protecting against moisture and dirt. In addition, it is easy to clean, which will allow you to return a snow-white, pristine appearance to your slopes with the help of an ordinary rag and soap. In addition, this paint is about twice as long as the usual paint, which will allow you not to return to prophylaxis soon.

Non-standard situation with the installation of windows

Sometimes when installing metal-plastic windows on old houses, it is not possible to use levels and plumb lines, because a window installed strictly according to the level will look very unaesthetic and strongly striking. In this regard, the plaster of the slopes will also be carried out not according to the level, but based on installed window... Therefore, using standard construction tools can be inconvenient.

Plaster templates are usually cut from materials at hand (a piece of plastic or a thin board) so that they can work in the most difficult to reach places. When installing metal-plastic windows, such are the sides of the slope closer to the window frame, where the use of a large metal spatula will be prevented by the opening sash of the window, which protrudes. A correctly cut template will be able to reach this place and in one motion, along with the entire area of ​​work, align it.

Templates are usually applied without using a level and plumb lines, that is, plastering is done by eye in connection with the above method of installing windows.

From the video you will get acquainted with the secrets of plastering window slopes with your own hands.

Do-it-yourself plastering of window slopes is an excellent and economical solution, which is popular, despite the prevalence of plastic on the market. Below we will describe this procedure in detail.

The plaster of window slopes retains its popularity due to some of its advantages:

• Availability. The plaster mix costs very little, and this is what attracts attention.
• Showiness. The place of decoration will look very beautiful, subject to all the rules.
• Lack of emptiness inside.

The finishing of slopes with plaster gradually fades into the background, giving way to PVC panels... This is largely due to the disadvantages of technology:

• Risks. During work, there is a high probability of damage to the frames.
• No additional insulation. The use of this technology complicates the process of creating a heat-insulating layer.
• Poor resistance to temperature extremes. If you live in a sharply continental climate (for example, Eastern Siberia), then cracks will begin to appear in a few seasons.

Tip: to extend the operating period along the perimeter of the slope at the points of contact with the frame, make small grooves with a knife. We squeeze out acrylic sealant into them. This technique is relevant only if the window slopes are plastered with gypsum plaster.

• Labor intensity of installation. Despite its simplicity, such work will require a lot of effort.

Conclusion: there are more disadvantages and they are more significant than the named advantages.

We do the job correctly

Some people wonder, first is the window sill or the plaster of the slopes? We highly recommend the second option. In this case, the window sills will remain intact. Otherwise, during work with cement mixture they can be damaged. Next, we will consider in stages everything that needs to be done.

What tool need to be prepared

We need the following list of tools:

• Level (if funds allow, then laser).
• Roulette, pencil (or marker).
• Rule (preferably aluminum).
• A set of spatulas.
• Malka (made of plywood or sheet of metal) - it should ideally fit the depth of the opening. It can be made independently from scrap materials.
• Containers for water and mixing.
• Master OK.
• Square.

When choosing a mixture, pay attention to its characteristics. It is advisable to use moisture resistant analogs. The use of cheap unstable mixtures will force you to perform surface restoration almost every year.

Preparing the original surface

In our case, preparation is the most laborious and time consuming process. You will need to do the following:

Now let's take a closer look at how to make slopes on plaster windows. Most people are familiar with trowel work. However, each case will have its own nuances. Let's analyze the work in stages - for a better perception of information.

Important! You can work at a temperature of at least +7 degrees (at different manufacturers may have their own requirements). It is also undesirable to work at high humidity, because in this case the solution will dry out for a very long time.

• First, the markup is done. Using a square, draw the line of the future opening.
• We create limiters for finishing the side parts of the slope (so as not to go beyond the applied markings). We cut out three strips of plywood and screw them onto self-tapping screws around the entire perimeter of the window. It is necessary that the edges extend beyond the edge by the appropriate distance (according to the markings applied earlier).
• It is necessary to achieve perfect evenness - we set the horizontal edge using a level, and the vertical posts with a plumb line.
• Following the instructions, we prepare the solution - it is better in small portions so that it does not have time to set, especially if you do not have the appropriate experience. To speed up the mixing process, use a screwdriver with a mixer attachment. We achieve the consistency of "liquid sour cream".
• We throw the mixture onto a plane using a small spatula. We completely fill the space between the beacons.
• Armed with a wide spatula, smooth the surface. We do this from bottom to top in smooth circular motions. We achieve maximum evenness.
• Let the mixture dry (not completely).
• Then we make undercuts in the places where the beacons are installed and take them out. Do this carefully so as not to damage the plaster layer.
• We cover the gaps that have appeared and let the surface dry.
• We proceed to the following procedures only after the mixture has completely dried.
• We evaluate the evenness of the surface - if necessary, apply another leveling layer.
• After drying, slightly moisten the surface with water from a spray bottle.
• Armed with a grater, we do the grout. We drive along the surface with smooth circular movements (as with manual polishing). We do this until the surface is perfectly flat.

Conclusion

As we said, putty is not the most durable option. However, there are ways to extend her life. You can paint it with enamel, which will give increased strength. If the aesthetic characteristics of this paint material you do not like it, you can immediately after drying, cover the surface with a PVA solution (1 to 1 with water). As a result, a transparent waterproof film will be created on the surface.
