How to plaster the slopes on the windows

How to make slopes on stucco windows? Such a question is facing the owners of their homes when replacing windows. Repair is not considered complete until the slopes are in order.

The article suggests getting to know how to plaster slopes on windows to reliably protect the entire structure from moisture and cold. A novice can do similar work, if you really want to do the repair yourself, which has certain information, and he does all the operations carefully and carefully.

Why do you need slopes on the windows, their types and features

Slopes are a part of a wall located between its corner and a window.

They are:

• Domesticconstituting the interior of the wall.
• Outdoorlocated on the outside of the building.

The functions of these elements include:

• Giving a finished look to the window opening, which will make it possible to decorate it, emphasize the general style of the room.
• Hiding mounting elements.
• Improving the thermal insulation of the room, shifting the "dew point" beyond the boundaries of the room.

The very first appeared plaster slopes, which are carried out by applying one or more plaster layers, followed by coating the top layer with paint. When installing such slopes, a lot of debris and dust appears, and in terms of the completion of work, they take a lot of time.

With the advent of new materials and technologies, plaster slopes began to be replaced by:

• Plastic (see Plastic window slopes - installation steps). Materials for their manufacture are taken:

1. plastic panel that does not have a heater;
2. a sandwich panel is a two-layer material, it already contains a heater. This is the warmest type of slopes for windows, with the longest service life, commensurate with the service life of the metal-plastic structure itself.

• Plasterboard. These are slopes, the material for which is moisture-proof drywall, with its subsequent coloring in any color that the customer wishes. As a rule, he is selected in white. The space inside the slope, if necessary, is laid with a heater, which can be polystyrene foam or mineral wool.

The advantages of such materials:

• Low price.
• Speed ​​of work.
• The presence of a small amount of debris and dust.

Materials and tools for work

Before plastering the slopes on the windows, you should prepare:

• The construction level, up to one meter long, but not very short, will be inconvenient to work with.
• Aluminum rule.
• Roulette.
• Plaster, water and primer dilution tanks.
• Small spatula.
• Master OK.
• Smoothers large and small.
• Wide spatula - 45 centimeters.
• Sponge grater for applying gypsum compositions.
• Grater and grater for working with cement mortar.
• Special gun for sealant.
• A sharp construction knife.
• Spray or brush for applying a primer.
• Corner profiles, window rail.
• A simple pencil.

Tip: To work, you need to make a small goat, on which it will be more convenient to perform all operations. Do not putty on a stepladder or stool, which can be quite dangerous.

The choice of how to plaster the slopes on the windows depends on the presence and level of humidity in the room and the location of the slope - inside or outside the home:

• In rooms where there is high humidity and for structures located outside, it is better to take cement compounds.
• Work inside the room can be performed with lime-gypsum, gypsum mixtures.

In addition, you will need:

• Foam, for blowing cracks in the window unit.
• Primer (seeWhy do we need a primer: technological nuances of finishing work) deep penetration.
• Headdress.
• Nitrile gloves to protect hands from solution.
• Overalls.
• Comfortable shoes.

Slope plastering

To properly design a window, it is necessary to mount all its elements in a quality manner:

• Windowsill.
• Window unit.
• The correct ebbs.
• The slopes themselves.

How to prepare a window for plastering slopes

Before plastering the slopes on the windows, you need:

• Decide on the type of solution.
• Perform priming work. The use of a primer improves the adhesion of the mortar for plaster with any base for slope. Depending on the material of the execution of the side surfaces of the window, which can be very different, the appropriate mixture for the primer is selected.
• After processing, the surface should dry completely.
• Steam isolation is in progress. The end elements from the side of the room are closed with a vapor barrier film or silicone sealant is applied to them. In the absence of this stage, over time, the foam will become wet from the condensate, which will violate its thermal insulation properties, it may begin to crumble and collapse, this will lead to fogging of the window, a draft will stretch from it.

Tip: You should choose a frost-resistant sealant, apply it only on a dry surface, immediately removing excess. When they freeze, it will be practically impossible to do this.

General rules for finishing window slopes

There are several basic rules when making window slopes:

• Putty of slopes is carried out:

1. for cement-based solutions - at temperatures above (+ 5 ° C);
2. for gypsum mortar (seeGypsum putty: its advantages and problems of use) - (+ 10 ° С).

• The instruction on the packaging allows you to properly prepare the plaster mortar. Do not use an expired composition.

Tip: Do not immediately prepare a large amount of solution, especially gypsum, which quickly hardens.

• The amount of material needed depends on the total slope area and the required thickness of the coating layer.

Stucco window slopes

Further work is carried out approximately in the following sequence:

• Remains of plaster and mounting foam are removed from the window opening.
• The surface is treated with a deep impregnation primer.
• Special galvanized metal corner profiles are used to reinforce the plaster. Their position is controlled by level. These elements are used as beacons that protect the corners of the structure from accidental mechanical damage.
• A special strip with two gutters, having the form of two shelves, is fastened or glued:

1. one holds the bar on the slope of the window;
2. the other serves as a guide defining the plastering plane.

Tip: To protect the window glass from dirt, when performing work on plastering slopes, it must be sealed with a protective film.

• To conduct quality work, it is advisable to use a special template, you can do it yourself. For this:

1. a piece is taken from the old plastic window sill;
2. cut off at an angle to form a hard, sharp and even edge;
3. the width of the part should be slightly larger than the corresponding size of the slopes themselves.

How to apply plaster on slopes

Plastering

Work instruction:

• The location of the slope angle is determined.
• A rule is set using a level and a pencil, a mark is made.
• The template is tightly pressed to the angular profile and the bar near the window.
• The solution is slowly smoothed from the surface, as shown in the photo, to even out the layer.

Slope manufacturing

• The rule is removed by slowly moving it along the corner.
• The surface is carefully inspected. In the presence of defects, an additional portion of the solution is made, and the slope is re-leveled with the help of malka.
• After a few minutes, the superfluous is removed and the rule is vertical alignment.
• Small irregularities are removed with a grater. In this case, gypsum plaster must first be soaked with a sponge.
• Grouting is done in a circular motion, gently pressing the grater.
• The surface is smoothed with a wide spatula.
• The slope is left to dry.
• Finishing is in progress. It could be:

1. staining;
2. tile laying, in this case, small irregularities should not be removed.

• After the work is completed, the end of the window sill is gently broken off, the paper and film are removed from the elements that were protected from the ingress of solution.

How to make slopes for plastic windows

If there are windows made of plastic, there are some recommendations:

• After plastering the slope, a groove with a width of up to 5 millimeters is made with a spatula, between the frame and the slope.
• The notch is filled with silicone, which is a protective gasket. This will avoid the occurrence of cracks at the junction of the window and slope.

High-quality plastering of slopes will improve the thermal insulation of the home, emphasize the beauty of the premises. If you want to learn more about how to plaster the window slopes, you are invited to watch the video in this article. Window decoration affects the overall style of the interior.
