Finishing window slopes inside with their own hands: options and technology works
If you also decide to install, you will certainly come across the need to finish the surface around the perimeter of the opening. The raw strip will have a width ranging from 5 to 15 cm (it depends on the building structure). The strip is called a slope, it must be covered up necessarily. But first you need to familiarize yourself with what is needed for this.
Finishing window slopes inside is the final stage after the installation of windows. This procedure is necessary, because otherwise the opening will look unaesthetic. Old slopes are destroyed after the dismantling of wooden frames, they must be closed, which especially concerns the seam. It is filled with foam. This allows you to make the opening more frost-proof and get rid of problems with windows.
If the slopes are trimmed correctly, they will not be afraid of temperature changes.Excess moisture will not appear on their surface, and the heat and noise insulation properties of the aperture will increase. However, property owners quite often refuse to finish the slopes, putting these works in a distant box. Many believe that if the window zapenit, then nothing will happen to it. However, the waiting period for repair is delayed for a long time.
How to prevent mistakes
Experts say that this approach is not correct. The gaps between the glass are sealed with mounting foam, which has soundproofing characteristics. The sun is affected by the foam, which can make it unusable. Foam increases in volume and begins to crush itself. Therefore, a gap appears between the foam layer and the frame after some time.
Why you need to hurry
In its open form, construction foam does not perform waterproofing functions. It absorbs moisture, destroying the material when the temperature drops. Foam, being a long time in the open, loses its insulating properties. It begins to collapse by 50% when its humidity rises by only 5%.
Use plaster and paint
Finishing window slopes inside can be carried out with plaster. It has a low cost. Before starting the cement-based composition must be diluted. The surface around the glass is cleaned, dust and bituminous spots are removed from it. Concrete beads in the corners must be cut down.
To improve the adhesion of masonry and plaster it is necessary to embroider the seams by 10 mm. Once the surface is plastered, it is necessary to level the angles of the slope. You can start laying a new layer only after the previous ones have dried, for this reason this method can be called long. The plastering procedure can take up to 3 days. The layer is quite thick in some cases, it is caused by the irregularities of the walls.
When finishing window slopes inside with a plaster, a small amount of the mixture should be applied to the groove. This fragment is left until dry. After that, the plaster is applied in a small amount and compared until the sinuses are filled. In one opening, the applied layer should not exceed 7 mm in thickness. It should be leveled, guiding the movement from the bottom up.
To align docking lines, you need to apply poluterok. Between the wall and the box when finishing you need to keep the angle. Angles should be the same.On the entire surface of the slope before plastering it is necessary to strengthen the wooden rail with a horizontal edge. It can be strengthened with nails, and plaster plaster is acceptable.
On the sides of the surface can be installed slats. Leveling the mixture is carried out with a wooden stick, which has a rounded handle. One end of the tool must be installed on the box, while the other - on a wooden rail. It is possible to begin the alignment of the edge only after the mixture begins to set. After applying a covering layer, which must be wiped. As soon as the plaster dries, the slats must be removed. The remaining parties get off in the same way.
The nakryvochny layer should have a thickness of 22 mm on all slopes. When finishing of window slopes inside is carried out by plaster, it is not necessary to open windows. If the mixture gets into the fittings, it damages it, as a result, the window will not cope well with the tasks assigned to it. An even layer of plaster will allow the window to open and close normally during the whole operation.
The disadvantages of finishing plaster
Although the plaster finish is fairly cheap,Some property owners refuse to use it, because this method has some drawbacks. Among others, it can be noted that the mixture is not reliably connected to the plastic frame, which leads to the appearance of gaps between the slope and the surface of the frame.
Seasonal temperature drops and the lack of elasticity of the mixture contribute to the formation of cracks on the surface. Among other things, the plaster has no special insulating properties, which causes condensation and mold.
You can be made to finish the window slopes inside the drywall. This method is traditional, it is preferred because of the moisture resistance of the material. This quality is especially important for windows, because they often form condensate. You can also take ordinary drywall, which is treated with a primer applied in several layers. To do this, use a moisture-proof composition. As for moisture resistant GCR, it has high rigidity, high thermal stability and excellent thermal insulation.
If you carry out the finishing of the window slopes inside with your own hands with the help of drywall, then you will get many advantages over plastic finishing. The advantages are low cost materials and the possibility of repairs. Damaged place can be putty and paint over.
Drywall is also good because it is able to maintain optimal humidity indoors. It absorbs the excess, giving it back when the humidity level decreases. But if it exceeds 75%, the drywall can swell, losing its characteristics. When choosing it, you must be prepared for negative moments: the material has low strength, so the slope can be damaged by mechanical action.
Method of work
Finishing window slopes inside a wooden house can also be carried out with the help of drywall. It is fixed on a metal or wooden crate. You can use a mounting foam for this, if the putty does not set well. An alternative solution is glue. After mounting the window, the excess foam is cut off, the old finish is removed. Treat the surface with a primer.If there are cracks and gouges, they should be leveled with plaster.
In order to prevent the penetration of moisture into the drywall and prevent the occurrence of mold, it is necessary to saturate the slope with a moisture-resistant composition. Drywall is cut. Sheet must be marked by the parameters of the window opening. It is necessary to use a special knife for cutting. The slope is collected from the top panel. The glue is applied to the sheet with a solid stripe. Its width should be 2 cm. The panel is installed in the starting strip, while the second edge of the sheet is pressed against the wall. Then you can proceed to the side panels, which are inserted into the grooves.
All joints are treated with a neutral sealant. When finishing the window slopes with plasterboard inside the room, it is important to eliminate the premature wear of the corner. For this purpose, paint corners of aluminum or galvanized steel are used. In those places where the gypsum plasterboard enters the profile, you should stick a tape-grid so that there are no cracks. Then the surface is prepared for painting, for this put several layers of putty, well rubbing the surface.Paint drywall can be acrylic or oil paint.
The most versatile are plastic slopes. In their designs there is mineral wool, which gives the products hydro and thermal insulating ability. Plastic can last more than 20 years. It is rational to install it for the reason that the slopes can be made on the same day when the windows were installed. Work takes not much time.
Plastic openings have high moisture resistance, rigidity and strength. They do not fade, are easy to clean and do not mist over. Material corresponds to that of which the double-glazed window is made. Therefore, when temperature drops, expansion occurs in the same way, and there is no excessive stress in the slopes. Additional painting work is excluded. The openings get a finished look, so they are perfectly combined with other structures in the room.
You can also carry out the finishing of the window slopes inside the sandwich panels. They are products of two sheets of plastic, between which is extruded or foamed polystyrene.The thickness of such panels can vary from 8 to 36 mm. When facing the window opening, it is better to use panels that are 1 cm thick.
The basis can be plastic or wooden openings, the width of which varies up to 150 cm. The advantages of the panels are that they do not need to be insulated, because the corresponding material is embedded in the design. But such a finish also has some drawbacks, one of which is expressed in the fact that the panel can exfoliate under the influence of moisture.
Recommendations for the work
Finishing window slopes inside the plastic with their own hands provides for work on the installation of products the next day so that the mounting foam dries well. For the best insulation performance, slopes are installed at the same time as sills. Sandwich panels can be fixed by one of several methods, but the most common of them is described below.
When finishing the window slopes inside with plastic, the ends of the panels are attached with dowels to the base, after the wizard begin to install fasteners and decorative corners.The joints between the panels and the window sill are treated with PVC-based glue. You can use a neutral sealant for this. If you compare it with silicone, it does not have a sticky consistency; as a result, the seams do not turn yellow when contaminated.
Using wall panels
When choosing materials for finishing window slopes inside, you should pay attention to the wall panels, which are not so expensive compared to the sandwich counterpart. Panels are hollow products, inside which the stiffeners are located across. The thickness is one centimeter, while the width can vary from 25.39 to 37.5 cm. As for the length, it is equal to 2.7 or 3 m.
Decorating window slopes inside the plastic is carried out in cases where the depth of the plane does not exceed 25 cm. This is true for the reason that wider openings do not allow to achieve rigidity and strength of the coating.
