Whether you’re updating the exterior weatherproofing or updating the interior design, this do-it-yourself project will improve the look and feel of your windows.

Application

Slopes for installed window structures can be created from the inside of buildings as well as from the facade (outside).

Slopes made for windows with various profiles: aluminum, plastic, and, upon request from the owners, wooden.

Slopes create a more aesthetically pleasing space by keeping the wall surface where the window structure is located safe from wind, effectively sealing crevices, preventing freezing, precipitation, and condensation, and preventing the growth of mold.

Slopes also provide an extra layer of security against dust, noise, and other unwanted sounds. They also keep rodents and insects out of the room.

Vital. Putty slopes aid in maintaining the integrity of the assembly seams following window profile installation by shielding them from UV ray exposure, temperature fluctuations, and the loss of the construction foam’s strength, density, and tightness.

Technical requirements

Made in a factory from natural minerals, putty is an eco-friendly material. It is available as a dry powder with a uniform structure, and when diluted well with clean water, it forms a plastic mass.

The following are the GOST 10277-90 basic technical requirements for building materials meant for window slopes:

1. Available colors: white, light gray, pinkish, greenish, gray, brownish-red, which after drying becomes lighter by 1-2 tones.
2. Ideal temperature for work is 20-21°C. The permissible minimum operating temperature is +7°C, and the maximum is +32°C.
3. Strength index – up to 50, elasticity – up to 100, viscosity – up to 20-30.
4. The surface after application should be flat, as smooth as possible, without flaws or bubbles.
5. Minimum drying time – 3 hours.
6. When working with putty, it is advisable to comply with sanitary and fire safety rules.
7. Better adhesion to the surface – after degreasing with acetone or priming.
8. A high-quality composition should not flow from the surface.
9. Can be sanded with or without water.
10. Acceptance of finished products according to the rules undergoes laboratory tests.

The putty is created as a diluted, dry substance that is ready for application. The dry composition, which ranges in weight from 5 (kg) to 15, 20, 25, 30, and 50 (kg), is packaged in three-layer paper packaging meant for long-term storage.

The manufacturer places the batch number, manufacturing date, storage guidelines, and dilution instructions on each package. Buckets are used as plastic containers to produce the wet composition.

Crucial! Once opened, the putty can be used for six to eight months.

Varieties

The purpose of the putty (inside or outside), the room’s microclimate (humidity indicators are crucial), and the putty’s manufacturer (quality, price, guarantees, certificates) all play a role in the selection process. Putty is regarded as a special substance that works on any surface, including wood, aerated concrete, brick, and monolithic surfaces.

Among the putty varieties are the following compositions:

1. For interior work:
2. starting – is characterized by structural lightness, well levels and strengthens the surface, masks any imperfections;
3. finishing – has a lighter shade compared to the starting one, and forms additional protection for the surface, as well as its ideal smoothness;
4. universal – used as a base and finishing layer, suitable for all stages of installation.
5. For outdoor use:
6. waterproof – especially recommended for areas with high humidity. It contains special polymer additives that give the mixture, after the layer has dried, additional protection from moisture (condensation, precipitation);
7. frost-resistant – suitable for regions with low temperatures during the cold season, can be used in work at temperatures below 0°C. It is highly resistant, thanks to the anti-frost reagents included in the composition, strengthens and protects the surface from destruction caused by sub-zero temperatures. Also recommended for renovation work at any time of the year.

Putty is separated into the following categories based on its internal structure:

• cement-gypsum;
• acrylic (polymer);
• plaster;
• polycement;
• latex;
• oil-glue;
• glue (PVA).

On the packaging, the manufacturer himself designates the variety to which a specific type of putty belongs. As a result, selecting the wrong building material at the time of purchase is just not possible.

Crucial! The material is moisture-repellent because cement makes up a large portion of its composition.

Tools and Supplies

The following supplies and equipment are needed by the master to complete work on window slopes:

1. Set of spatulas with wide and narrow blades: small and trowel (application), medium and large (smoothing).
2. Selected type of putty (composition: starting and finishing).
3. Bucket or any other container (for diluting the putty composition).
4. Special mixer (kneading) or drill with attachment.
5. Construction tape, a simple pencil, a plumb line and a level (marking and maintaining horizontal and vertical lines).
6. Clean running water (formation of working mass).
7. Roller and brushes (for uniform distribution of the solution along the slope, priming).
8. Drywall sheets, self-tapping screws, screwdriver (surface leveling).
9. Ceramic tiles with adhesive, paint, wallpaper (for additional finishing, depending on the design of the room).
10. Metal perforated plates-angles (perfect alignment of near-window space).
11. Eskaric paper or grinding machine (creating additional smoothness before painting and other finishes).
12. Plaster composition (if necessary more thoroughly alignment).
13. Chancellery knife (formation of cuts of drywall sheets).

The owner of the home, apartment, or cottage won’t need to prepare tools or consumables if he contacts the experts of the construction company.

Specialists have access to the tools needed for their jobs, and the suggested consumables—builders purchase materials in bulk—will be significantly less expensive than those on the market. Customers are therefore responsible for paying for the use of consumables in accordance with the official price list.

Preparation of the solution

Making a solution with your hands is not hard at all.

To accomplish this, fill the container with the necessary quantity of dry putty, then add water and stir the mixture slowly until it becomes creamy.

The solution is viable for one to two hours. Plaster is prepared using the same principle and is always applied before the starting layer if it is required before puttying.

In addition to using mechanical tools like a drill with a special attachment or a construction mixer, you can manually prepare the solution with a spatula or trowel. The composition is more uniform and plastic after being kneaded mechanically, which also shortens the time needed to prepare it by hand.

Following the dilution proportions is crucial while working; for high-quality products, these are specified as volumes of dry putty and water on the packaging.

Skilled artisans pay close attention to the final consistency, making sure it’s not overly thick and, if needed, thinned with water. Create formulations in modest amounts. Mix a fresh solution once it has been used up.

Crucial! For optimal plasticity, experts advise infusing the solution for up to ten to fifteen minutes prior to installation.

Application Features

Strict adherence to technical guidelines and the uniform execution of all primary and preparatory stages are prerequisites for this kind of work. Initially, you must ensure that the slopes’ walls are perfectly smooth. Use plasterboard sheets and perforated metal corners (GKL) for this.

The gypsum board is covered with a primer composition first, followed by the ready-made plaster, putty, and starting compound. The finishing layer is applied to the starting layer within 6–10 hours of the surface drying, resulting in flawless smoothness.

The surface can be covered with wallpaper, painted in any color, or trimmed with ceramic tiles once it has dried. Make sure, however, that it doesn’t require sanding first (using sandpaper or a specialized grinding machine).

How to apply putty to window slopes:

Possible difficulties and errors

When working, novices may commit the following errors:

1. Replacing gypsum boards with sandwich panels (cold bridges are formed).
2. In humid rooms or climates, it is undesirable to insulate walls under plaster with mineral wool, as it strongly accumulates condensation and changes structurally over time, deforming the surface.
3. Lack of preparation and use of low-quality materials.

These guidelines must be adhered to in order to avoid mistakes when installing slopes:

1. Plaster, level and clean the working area (removing debris and unevenness promotes good adhesion of the building material).
2. If dismantling of the old finishing coating is required, it is better to do it immediately.
3. In your work, you must use consumables only from trusted industrial companies, with good expert and user reviews.
4. A base layer of putty mixture is applied to a thoroughly (1-2 times) primed surface.
5. The finishing layer always follows the starting layer.
6. The best composition for slopes is considered to be a specialized type, the packaging of which should indicate: frost-resistant or water-resistant.
7. Compositions with a large amount of cement are suitable for outdoor work and rooms with high humidity levels (baths, bathrooms, swimming pools).

Reinforced mesh can be used to better apply the starting base in challenging situations when forming slopes. Fibreglass, plastic, or metal can be used to make the mesh.

Crucial! Painting can be done in 1-2 layers to achieve a more saturated tone in wet rooms. It is best to finish the slopes with tiles.

Advantages and disadvantages

The benefits of arranging slopes along the window area’s perimeter are taken into consideration based on its intended use.

• masking any installation defects;
• additional thermal insulation;
• creation of a reliable, durable, stable structure;
• aesthetic orientation;
• noise protection;
• budget for purchasing and ordering work;
• easy care of the window area;
• painting in any color;
• rapid surface restoration;
• cold resistance;
• high speed of installation and finishing;
• no seams.

Slopes have only one drawback: they can be mechanically damaged.

The slopes highlight the window structure’s uniqueness and style while also fitting in nicely with its interior.

Average prices in the Russian Federation for work

Puttying costs per linear meter (p. m.) are listed in official construction companies’ price lists and range from 200 to 600 rubles on average in the Russian Federation.

The total cost, expressed in rubles per hour, is made up of a variety of these services:

1. Dismantling of old coating (material) – 200.
2. Surface priming – 30-35.
3. Plaster (if necessary) – 450.
4. Putty work (start, finish) – 380.
5. Painting the slope – 180.
6. Installation of gypsum boards and perforated corners – 320.

Each case is unique when it comes to working with slopes, and it all depends on the kind of surface and quantity of construction services needed. The area has an impact on labor costs as well. The northern regions (25–40% more expensive than above) and Moscow, Moscow Region, St. Petersburg, Novosibirsk, and Bryansk had the lowest prices for slopes and work with them.

Crucial! Independent contractors charge twice as much for their work as skilled artisans. For the paid service, there will be no guarantee and the work quality might be lower.

It is essential to properly putty window slopes for moisture resistance and aesthetic appeal. You can guarantee long-lasting and tidy finishes both inside and outside your windows by selecting the appropriate mixture and applying it correctly.

Take into account the particular needs for both interior and exterior slopes when preparing the mixture. Simple joint compound or spackling paste will do for interior slopes, giving a smooth surface ready for painting or wallpapering. However, exterior slopes call for stronger materials, like weather-resistant exterior putty or exterior-grade joint compound.

The putty type used determines the application techniques. Using a putty knife, evenly apply the mixture to interior slopes, making sure the surface is flush and blends in seamlessly with the wall. A smoother finish can be obtained by lightly sanding in between coats of paint. To ensure weather resistance, exterior putties frequently need a stronger adhesion and may need to be applied using a slightly different technique.

Make sure the slopes are clear of debris and clean before beginning, as this can have an impact on the finish’s quality and adhesion. It’s also crucial to properly seal any gaps or cracks surrounding the window frame to keep moisture out and preserve energy efficiency.

You can effectively putty window slopes yourself, improving the look and functionality of your windows while guarding against potential damage, by following these steps and using the right materials. Your window slopes will last longer with regular upkeep and recurring inspections, keeping your house safe and attractive.
