Plastering slopes of windows, doors and arches

28.02.13 02:39

The slope is structural element window or opening that adjoins window frame or door frame. Any slope can be made either at a right angle or with a divergence at different angles.

Slopes are external and internal. In the first case, moisture-resistant and frost-resistant materials are used, such as DSP, as well as special plaster mixtures For exterior finishing. When calculating the cost of working with slopes, the distance between planes, the width of which is up to 50 cm, is calculated.

Today the modern construction market can offer its customers big variety finishing materials for slopes, namely PVC, wood, MDF, plasterboard, plaster mixtures and much more.

As a rule, wood is undoubtedly environmentally pure material, which cannot be said about plastic. Thus, plastic slopes and sandwich panels are a controversial solution from an environmental point of view, but they are very convenient and practical to use. As a rule, wooden slopes are used for door and arched openings, while at the same time plastic sandwich panels have found their use in finishing window openings. The most suitable solution There will be plaster slopes that are environmentally friendly and durable. In addition, joints, edgings and plastic corners will not be visible.

It is worth noting that it is best to plaster slopes in new buildings or in non-residential premises during capital construction, where plastering of walls is necessary. This process unlike other options for finishing slopes, it is considered the most labor-intensive and is completed over a longer period of time. If you have replaced windows in a residential area, it is best to finish the slopes using plastic sandwich panels; it will be much cleaner and faster.

Plaster slopes

Plastering slopes today is in the classic way finishing works. Such slopes sometimes provide an opportunity to get excellent results. Regarding the percentage of application this method finishing, I would like to note that it is not great. This is due to the variety of new finishing materials.

Let us pay attention to arched windows; in this case, any arched slope is made only by plastering, since it is simply not possible to make a slope from a PVC panel or a sandwich panel.

Plastering slopes of windows, doors and wall corners and instructions

After installation and final fastening of windows and doors, preparation and leveling of walls, as well as their preliminary finishing, the slopes are plastered. This traditional method of leveling the surface using special dry mixtures helps to make it complete and aesthetically pleasing. In each individual case, different solutions and technologies are used, when choosing which it is worth taking into account the object and its further operation.

Insulation and soundproofing of slope

Depending on the design and installation of the double-glazed window or door, there may be gaps between the wall and the frame different sizes. If they are more than five centimeters, which is often found in old houses, then plastering window slopes includes two mandatory stages - insulation and sound insulation.

The space between the box and the wall is filled with heat-insulating materials. Usually they are lightly moistened with gypsum mortar and compacted along the entire perimeter of the window, leaving 2-3 cm for filling with the main mixture. If, after installing the window, sounds are clearly audible from the street, then the gaps are additionally filled soundproofing materials.

When installed correctly, there are practically no holes left between the windows and the wall, and they can be filled polyurethane foam, which also has good insulating properties. After it dries, the window slopes are plastered.

Preparing for work

To better penetrate the room with light, plastering the slopes is carried out at a slight angle. It is measured with a special square.

This is done very simply: we cut out a corner from the extreme corner of the board, taking into account that the layer of plaster extends onto door frame by about 5 mm. The even door frame and our installed perforated corners serve as beacons for the plane of the plaster layer. With this *cutting piece* prepared to the size of the door frame, we will simply cut off the excess mortar that we put between the corner and the frame.

After we plaster the slope, we need to wait about 1 hour and clean the internal ones filled with gypsum mixture top corners on the slope. They are perfectly trimmed and leveled with a spatula, while the solution has not yet dried, but has just set on the surface

At the end of the story, watch a short video and understand how easy it is to do it all!

And the next day, after the solution has completely set and dried, we wash our metal door frame. After the solution has completely dried, you can begin to putty under or under the wallpaper.

Masking tape metal door It’s better not to paste it over, because Rotbant won’t do anything to it - and it will take a lot of time to wipe off well-adhered tape. Just place a wide spatula in the corner between the plaster layer and the box, and wash off the gypsum plaster from the metal with a sponge soaked in water.

When replacing windows or performing renovation work indoors, it is also necessary to work with slopes. Plastering slopes is a very labor-intensive and complex task, so you can do it better only when you have at least basic putty skills or experience plastering works. Without experience, it is unlikely that it will be possible to perform high-quality plastering on slopes. However, if you have the desire and perseverance, you can get the job done efficiently and quite quickly.

Preparatory stage

Before starting work, it is necessary to prepare or purchase everything necessary tools and materials. Some tools will definitely be needed, and the need for some is determined by the initial state of the slope and other factors. It is recommended to organize before starting work workplace. Near this workplace there should be access to sockets to connect a mixer that will be used to mix the plaster mixture.

To avoid staining the floor and surrounding surfaces, it is recommended to lay a large piece of thick oilcloth on the floor and place all tools and materials on it.

This way the room will be clean, and it will be easy to clean the workplace after the renovation is completed.

Selection and preparation of tools

What tools will you need exactly to level the slopes with your own hands:

An assortment of spatulas (preferably several pieces - 10 cm, 25 cm, a spatula whose length is slightly greater than the width of the slope).
A level whose length is slightly less than the height of the window or door whose slopes need to be processed. If only door slopes are to be plastered, it is advisable to choose a level of one and a half meters; if both window and door slopes are to be plastered, a level of 1 m is suitable. large area Using a small level is not recommended.
Rule. Its length must be greater than the length of the slope. If you have no experience working with the rules, it is better to choose aluminum, it is light and comfortable to work with.
Bucket for mixing and washing tools.
Cloths and brushes for washing tools.
A square designed for setting the beacon at an angle of 90°.
Rubber or rubberized gloves to protect hands.
Polishers or smoothers for comfortable work with a slope.
Container for primer (wide tubs are convenient).
Brushes, brushes and rollers for priming.
Mixer for mixing the mixture and whisks for it.

Depending on the selected sequence of work and method of processing the slope, the following tools may be needed:

dowels;
self-tapping screws;
hammer;
drills;
and so on.

Purchase of materials

To level slopes on windows or doors, you will need the following materials:

Primer. You can use quartz or one designed for deep penetration. It is not recommended to dilute the primer with water - when plastering, maximum adhesion between surfaces is needed.
Water. It is recommended to bring sufficient water to the work site before starting work. The larger the layer of plaster placed on the slopes, the faster the water intended for mixing the mixture will drain away. It is recommended to have 2 buckets - one for mixing plaster, and the second for washing tools.
Any starting gypsum putty (ideal for plastering door and window slopes. The mixture has high plasticity, is easy to apply, and is comfortable to work with. It does not dry too quickly, and is also easy to wash).

How to plaster slopes

The technologies for how to plaster door slopes and how to work with window slopes are practically the same. Difficulties arise when working with the upper slope due to its extremely inconvenient location in space. After completing work with the side slopes, it is easier to work with the top one. Firstly, I already have some experience in plastering slopes, and secondly, since the side slopes are adjacent to the top, part of the work on forming the corners has already been completed.

Beacon fasteners

Plastering of slopes is carried out according to installed guides. Such guides can be long rules, even and smooth wooden beams, long pieces of profiles and the like. It is much easier to carry out work relying on beacons. To install guides on side slopes, it is most convenient to use a starting mixture for plaster. Several spatulas of the mixture are applied to the wall, and the beacon is attached directly to the plaster. It dries, and the slope along the lighthouse is plastered.

As for the upper slope, it is best to mount the lighthouse using brackets, profiles or dowel installations. This is more difficult, but more reliable. A beacon that is not dry can slide off the upper slope, and thus the plane will be plastered crookedly. The same rule applies when leveling slopes doorways.

This way all planes will be processed sequentially. When installing the beacon, you should make sure that it is placed level. Since the beacon gives a flat surface, you should make sure that it is level. To do this, a level is applied to one of the sides of the beacon and the guide is aligned with the level. After this, they need to be left to dry to the wall. After about an hour you can start plastering the slopes.

Slope preparation

Before leveling the slopes with plaster, take several preparatory steps.

These include:

cutting off with a stationery knife the protruding mounting or adhesive foam that was used when installing the window;
window covering masking tape and stretch film to prevent plaster from getting on it;
wiping dust from slopes (to improve adhesion), window sills and windows;
primer treatment of the entire slope.

All this can be done while the beacons are drying up. At the same time, it is recommended to organize a workplace, prepare a mixture for plaster, a spatula and other tools that will be needed when working with a slope.

Plaster preparation

Before mixing the mixture, be sure to read the instructions on the package. Manufacturers give different recommendations regarding mixing specific putty mixtures. Therefore, to achieve best result and reliability, all manufacturer’s recommendations should be followed. When mixing the mixture, it does not matter whether the door or window slope will be plastered. It is important that the mixture has a consistency so that it will not flow or slide down the slope. At the same time, it will be comfortable to work with and there will be time before it dries to level the surface.

It is best to stir the plaster with a mixer. It is best to test what consistency it is with a small spatula - 10 or 15 cm.

Bucket in which plaster for slopes is mixed front door, interior doors or windows should be clean. Before mixing a new portion of the mixture, the bucket should be washed with a brush and rinsed.

Leveling the slope plane using a mixture

When the surface and the plaster mixture are prepared, they begin to apply it to the slope. Plastering process door slopes does not differ from window treatment, the technology for carrying out the work is the same. Using a spatula, the mixture is applied to the slope. It is recommended to process small areas, 20-30 cm each.
First, the mixture is applied to them, and then using a trowel or a wide spatula it is leveled. The spatula or trowel used to level the slope should be held at an angle of 90° to the plane of the slope, perpendicular. This way you can achieve an even and smooth slope.

The door itself will hinder movement when working with the slope, and there is a high probability of getting it dirty. It is best to work with slopes after installing the box.

Final work

After the slopes are plastered, you need to wait for it to dry completely or partially and remove the beacon. Regardless of the method used to attach it to the wall, it should be removed in the direction from the slope to the wall so as not to damage the plaster layer. After removing the beacon, it will be noticeable that a small influx of plaster mixture has formed on the wall. It needs to be removed. If the plaster layer is still soft, you may be able to do this with a spatula. If not, you can use coarse sandpaper (number 40-80).

After the slopes are plastered, painting perforated corners can be installed on them. The corners help form an even angle and also protect the wall from chipping pieces of putty. After installing the corners, you can putty the slope with a finishing gypsum mixture.

Using the above scheme, you can align the jambs of doorways and window slopes. Working with plaster is quite dirty, so it is recommended to do it in clothing that completely covers your arms and legs. After finishing work, all tools should be washed with a brush under running water and then wiped dry (except for power tools). This way the tools will last longer.

It is recommended to carry out work on plastering slopes with your own hands in the absence of any experience in carrying out repair work after watching training videos.
If possible, you should consult with those involved in repair work or.

An obligatory part of a major renovation of a room is the alignment of doorways. Before finishing a room from scratch or making major renovation in the house, you should check with specialists on how best to level the doorway with plaster.

Plastering a door or window opening is quite difficult, so you need to have a little personal experience in this matter or simply invite a team of specialists. The second option is much more reliable, but it will hit the customer’s pocket harder.

Applying plaster to the surface will take a lot of time, but if you follow the process technology, the slopes will last for many decades. This option is only possible if there are high-quality Construction Materials, some personal experience and professional tools.

Before leveling the surface, you should define the concept of slope. The concept refers to the area in the area where the door is inserted, framing it from the sides and from the top. The use of plaster mixture in this embodiment allows:

will be able to perfectly level surfaces;
will reliably protect slopes and adjacent surfaces from destruction;
will increase the level of thermal insulation in the room;
will enhance sound insulation properties.

To get perfect slopes, you will have to choose the right plaster mixture. It is necessary to talk about the selection of initial and final plaster, since it is selected depending on:

features of the technical plan object;
features of further operation;
the cost of the work performed.

If the gaps are more than 50 millimeters, then before filling them with the plaster mixture, care should be taken to ensure maximum noise and heat insulation by filling doorjamb special materials.

Experts strongly recommend making plaster-type slopes from:

cement-sand composition - for which you should stock up on cement and sand (1:4), diluting them with water to the state of thick sour cream;
alabaster based solution.

If the structure is installed in compliance with all requirements, the gap is so small that it can be easily filled with ordinary polyurethane foam. After the foam layer has dried, it will be possible to carry out further surface treatment - plastering and decorative finishing.

For quality leveling door or window opening, it is strongly recommended to use branded devices, which can be purchased at any hardware store. Although just a few years ago plastering work was carried out exclusively with the help of a trowel and a painter's bucket...

Now, before leveling the doorway with plaster, the following is purchased in the store:

scraper - a small spatula used to remove old trellises from walls, the length of which is only four centimeters;
brush with metal bristles - allows you to remove old paint, but is often replaced with a drill with a chain for speed;
a plastic bucket for diluting dry plaster, the volume of which can be ten or twenty liters;
trowel and spatula for applying the plaster mixture - have the shape of a drop or an uneven rectangle, used for a flat surface or corners;
metal profile beacons with galvanized coating, which are necessary for leveling the surface;
plaster spatulas - for accurate selection, application and distribution over the wall surface plaster mortar you should purchase a wide and a narrow one (for applying the mixture to hard-to-reach areas).

It is necessary to clarify the best way to level the doorway with plaster, and then purchase the necessary tools. To work with this material, a plaster corner may be required, and in large quantities, because with its help you can make a spacer between the walls and the ceiling and properly plaster the doorway.

Experts say that plastering works need to be stocked up with:

usually - a metal strip, which removes excess solution from the surface;
trowel - a strip whose surface is polished, designed to smooth out the applied layer of plaster;
steel trowel - can replace a trowel, but allows you to apply a thicker layer of plaster.

For more comfortable production of high-quality slopes, you can stock up on a construction mixer or a hammer drill for thoroughly mixing the plaster mortar. If you have to plaster slopes not just once in a house or apartment, but constantly in industrial workshops or office premises, then you can’t do without a device for applying plaster.

Preparing openings

To decide on the best way to level a doorway with plaster, you need to listen to the advice of experts. In order for the layer of plaster to lay more evenly, it is necessary to properly prepare the surface of the openings.

In order to properly finish a doorway, it is necessary to prepare the surface of future slopes in advance according to the rules:

remove dirt and dust deposits from the surface;
eliminate stains from bitumen, resin, grease;
carefully prepare the corners in the area of the door leaf;
eliminate concrete deposits;
masonry joints will need to be cleared down a centimeter to obtain improved adhesion and increase the service life of the corners in the area of the door covering opening;
prime the wall surface using a special solution.

Installation of guides

In order to correctly align doorways using a high-quality and safe plaster mixture, you will have to install guide plaster corners and metal profile beacons in the door area.

In order to secure galvanized beacons, use:

solutions such as Rotband or MP-75;
alignment with respect to the wall itself and along the slope, without shifting the position of the beacon or corner.

If there is not one, but several doorways, then at the same time you will have to install a profile corner and beacons on the extreme slopes. Then the specialist waits for the mixture to harden, and then installs intermediate-type elements with parallel alignment along the line of those that were installed before.

It is common to use aluminum slats as beacons, as they can help protect the corners from damage. The rules for fixing beacons are simple:

cut off a corner according to the height of the opening;
cut the top corner at an angle of 45 degrees;
fix by applying the solution to the profile or directly to the corner of the door;
align the corner to the same level with the wall;
You can attach the corners with screws or nails.

If cement mortar protrudes during fixation, it will have to be carefully removed using a spatula. Determine how evenly the beacons and corners lie, perhaps measuring this value using a building level.

Rough plaster

The rules for applying plaster to door slopes are no different from most plastering works. To do this, apply a layer of mortar from the bottom up using a spatula or paint bucket to the area of the doorway, moistened with water and cleaned of dust and dirt.

Then the layer of rough plaster is carefully straightened using a rule or template along the guide beacons, and the excess part of the solution is removed back into the container. If the mortar is applied to corners or concrete beams with great difficulty, then before applying it the surface must be prepared (coated with a primer).

Applying the finishing layer

After the rough plaster has dried, you will have to make a finishing layer. This will have to be done after twenty-four hours for all possible defects to appear.

If you try to finish grouting immediately or after a couple of hours, you won’t get slopes because the solution:

will float;
will completely lose its shape.

A well-set plaster solution may crumble, but not float. For finishing, you should not use a solution that is too strong, since it will not only need to be applied, but also smeared. The surface of the slope should be as smooth as possible, and the solution will have to be poured into the holes and gaps.

Experts point out that there is no need to pull the solution in one direction. It would be better to do this in zigzags, as this will give additional smoothness.

Before installing the door in its proper place, decorative purposes should be sanded. To do this, after applying the finishing layer of plaster, but before it sets, you will have to carefully grout using circular movements special grater made of wood.

You can grind the surface of the door slope using two methods:

circular movements;
at speed, that is, with direct strokes of the grater.

It is possible to attach a felt pad to the surface of the trowel, since this makes the surface smoother and rubs the slopes better. As a rule, it is not necessary to sand the plaster, but if this is necessary, then it is worth using a piece of fine sand. sandpaper or a special trowel.

Methods for aligning doorways

To understand how best to level a doorway with plaster, you need to understand several techniques for this procedure. It will be possible to level the opening using the same plaster, and you can use it not only cement version, but also gypsum or polymer. Polymer and gypsum plaster, which is sold in the form of a paste.

You can level the opening using wooden beam, but only in houses with wooden walls, parallel to the block, it is possible to reduce the width or height of the opening and increase the height of the threshold. To do this you will have to stock up:

bar;
hacksaw;
antiseptic impregnation;
a piece of sandpaper;
varnish (paint).

Now leveling with drywall is used, since this option is inexpensive, and even a beginner can implement it. Drywall sheets allow you to make an opening for a door of any shape, but for this you will have to make a metal frame.

You will need to fix pieces of drywall onto the metal sheathing using self-tapping screws, while simultaneously plastering over the unevenness and defects. You should not use sheets of plasterboard thinner than 12.5 millimeters, or intended for the ceiling. For long term For operation, it is recommended to use green plasterboard, which easily tolerates moisture in the room.

Finishing of door slopes can be done either at a right angle or at any other angle; it can be external or external. The external one is made from moisture-resistant and frost-resistant materials.

For plastering the external slope, it is worth using special solutions designed specifically for this type of finishing. Currently, the construction market is very big choice materials for such work.

Selection of materials

Both wood and PVC, as well as special plaster mixtures, can serve as finishing materials. Slopes made of wood will be environmentally friendly, unlike plastic ones.

For doorways, wooden slopes are more often used, and for finishing window openings, more suitable option will plastic materials. One of the most durable and environmentally friendly slopes are plaster slopes. Due to the absence of joints and edgings, the products become more attractive. This type of finishing is most advisable to carry out in new buildings simultaneously with plastering the walls, since such work is quite dirty and time-consuming. When replacing windows, the most suitable option would be to install PVC plastic panels. Working with such materials is much cleaner and will take no more than a day.

Finishing process

Before plastering the door slopes, you need to make sure that the installation is secure. After which you can begin preparing the mixture. The solution for such work should be prepared at a ratio of one to three (a shovel of cement and three sands).

Plastering slopes is a classic. There are situations in which finishing in this way simply cannot be done. Such situations, perhaps, include the processing of almost all arched windows, because for such surfaces it is almost impossible to make slopes from other materials. The immediate advantage of plaster is that it makes it possible to process any shape. In addition, it is resistant to external mechanical influences, environmentally friendly and easy to repair or update. Among other things, the solution will fill all the cracks, which will add integrity to the structure and provide additional insulation. Before finishing the doorways, you need to install the frame, plaster the walls, and then proceed directly to the slopes.

In most situations, work is done using a template. You can make the desired template from any durable sheet material. But there are often cases when doors are not installed at all, and the slopes of the doorway are still plastered. What to do in this case? To begin with, metal plaster corner profiles should be installed on both sides, which will later serve as additional protection for the corner from external negative impacts, and the resulting space between the profiles is filled with solution (excess should be removed immediately). After everything is dry, you can start finishing slope

Before you start painting or applying thin wallpaper, the surface is first puttied.

Arched slopes

The side parts of the arch are plastered similarly to door slopes without installed doors, that is, using corner profiles installed on both sides of the opening. Additional attention Only the top rounded part is required. To do this, mark the location of the edges of the arch on the finished slopes. The bend of the arch should be reinforced with wire or thin reinforcement. For further work You will need a couple of templates; they can be cut from plywood or some other durable sheet material. Templates are cut out specifying the required radius of curvature and attached to the wall using dowels. After which the resulting void is filled with polyurethane foam. Plaster mortar is poured over the top of such a structure. Using a special semicircular grater, the radius of the arch is drawn according to templates. After the arch is completely dry, the templates are removed and you can begin painting or gluing the arch.

All surfaces are puttied before painting.

The process of plastering doorways is not complicated. But in order for the slopes to be smooth and beautiful, you need to be patient and persistent. Drywall is also used for leveling. Using such material does not require special skills. Drywall is easy to install without special effort. The only difference between such slopes is the quality and service life.

During the installation of new doors or when repair work In the house, slope plaster is most often used.

The advantage of plastering the opening is simple technology carrying out work, thanks to which even a beginner can cope with the task. Let's find out how to plaster the slopes of doorways with your own hands and what is required for this.

Key data and benefits

The doorway is formed using various materials, their quality is laminate, plastic panels, wooden elements. However, plastering is still the most popular today due to the following advantages:

Cheap material, the price of which is suitable for budget repairs
No seams, high strength
Plastering slopes is allowed both indoors and outdoors
Long service life

Before you independently level the slopes of a doorway with plaster, you should find out the disadvantages of this type of finishing:

There is a possibility of condensation, due to which fungus and mold will subsequently form on the surface.
Over time, the material will crack and may peel off from the frame.
A lot of dust and dirt during work

Important! If you plaster the slopes according to all the rules and regulations, you can avoid the appearance of many shortcomings.

Tools for work

Before you begin finishing work on the slopes of a door or window, you should select the right tool. When purchasing a plaster solution, feel free to ask for quality certificates for the mixture, they confirm the production of the plaster in accordance with all GOST standards.

The following tools are needed for plastering slopes:

Building level
Plastering rule
Goniometer
Tape measure or pencil
Spatula 50mm
Master OK
Container for plaster mortar

Advice! When choosing a spatula, take into account the depth of the slope - it will be difficult to smooth out the plaster if it is too narrow, and a wide one will simply not fit into the opening.

Features of repair work

Plastering slopes also means leveling them. First of all, the surface is prepared, on which both the quality and service life of the finish depend. Do not forget that when the doors slam, vibration is created, which negatively affects the slopes - strength in this case is extremely important.

Important! Video lessons for beginners describe all the details and subtleties of plastering slopes.

Many sources say that slopes should be leveled cement mortars, but if the finishing is done inside the house, then it is more relevant to apply gypsum material. These mixtures have moisture-resistant properties, they are much easier to work with and their drying time is much shorter. Another plus is the improved sound absorption properties of the gypsum mortar, which significantly improves the sound insulation qualities. When installing the door and frame, you should immediately think about the subsequent design of the opening:

Cracks and voids are sealed using polyurethane foam
Using a primer with deep penetration good adhesion of the plaster to the slope is achieved
Thanks to special corners you can create an even angle of the opening

When plastering slopes, pay attention to the depth of the opening - sometimes multi-layer application of plaster mortar is required. Reinforcing mesh is used to prevent cracking. After the plaster has dried, the surface should be grouted, which will reveal possible unevenness or differences. If any are identified, then another layer of plaster and re-grouting should be applied.

Every meter of area should be checked with a level - this will protect you from additional costs and plastering work. As finishing coating paint is suitable for the door slope or decorative putty. Each of these materials requires high-quality preparation and a perfectly flat surface. There is one secret that can be used as protection against cracking of the plaster in places of contact with the frame:

When the plaster is dry, make a slot small size in this place and fill it with sealant that can be painted
Using a rubber spatula, the sealant should be immediately leveled and after drying, begin finishing.

There are several mistakes that should be avoided when plastering door slopes:

You cannot plaster slopes in parts - with a long break, the surface is susceptible to rapid cracking
Cannot be carried out Finishing work when the base humidity is above 4%
When creating a metal box, you cannot use a grinder to cut profiles - this destroys the zinc layer and leads to corrosion and rust formation

Pay attention to the type of mortar you are going to use for slopes - not all are suitable for indoor use. As you can see, there is nothing complicated in upgrading a doorway, because for high-quality repair processes it is enough to adhere to all the rules and requirements, and also use only quality tools and leveling materials.
