Completing the window slopes is a crucial step that comes after installing plastic windows. Plastering the slopes improves insulation and seals gaps in addition to improving the look of your windows.
If you follow the proper procedures and techniques, plastering window slopes can be a simple task. It contributes to the installation’s overall neat and polished appearance by facilitating a seamless transition between the wall and the window frame.
This article will walk you through the essentials of plastering slopes so you can complete the job yourself and look professional. This information will help you complete the task correctly, regardless of your level of experience.
| Step | Description |
| 1. Prepare the surface | Clean the slopes from dust and debris. Apply a primer for better adhesion. |
| 2. Apply the first layer of plaster | Spread the plaster evenly on the surface using a trowel. Let it dry. |
| 3. Reinforce the corners | Use corner beads to strengthen the edges and prevent cracks. |
| 4. Apply the finishing layer | Apply a thin layer of plaster, smooth it out, and let it dry completely. |
| 5. Sand and paint | Once the plaster is dry, sand the surface and paint it if needed. |

Advantages of plaster
There are other ways to finish, that much is obvious. For instance, using panels composed of plastic, wood, or plasterboard. Plastering window slopes offers the following benefits:
- Long service life.
- Low cost of material.
- Ease of execution, you just need to choose the right thing to plaster the slopes with.
- Durability, strength.
- Good thermal insulation.
- Hiding of mounting parts if necessary.
Slopes of windows made of plastic or wood can be plastered.
After installing plastic windows, plastering slopes is necessary to create a neat, finished appearance and shield the window area from moisture and drafts. Plaster must be evenly applied, the surface must be prepped, and a smooth, polished finish that blends in perfectly with the surrounding walls must be achieved. Enhancing the appearance and usability of your new windows is an important step.
Tools and materials
To ensure accurate and convenient work, we will require:
- Spatula (trowel), or better yet several with different working surfaces.
- Simple pencil.
- Aluminum rule.
- Bucket for diluting the solution.
- Melka – a template cut out of a piece of plywood that allows you to do the work evenly.
- Stepladder or stool.
- Corner for plastering slopes, window strip. There are plastic or metal options. Such corners for plastering slopes can be bought or made yourself.
- Level.
- Roulette.
- Rubberized gloves.
- Sharp knife.
- Roller, brush.
- Mounting foam.
- Sealant, gun for it.
- Primer.
- Grater, if you have chosen a cement mortar; trowel, if you use a gypsum mixture for plastering slopes.
How to make a solution for plastering
Select the plaster to use for the window opening based on the room’s humidity level and whether the window opening is installed internally or externally. We must also consider that the composition needs to be frost-resistant because we live in an area where winter is the predominant season.
It is preferable to select a composition with cement for external slopes in an apartment with high humidity. Note that it provides heat-insulating and water-repellent properties.
Within the home, gypsum or lime-gypsum mixtures work well.
You can use acrylic material in both situations, but be aware that it is not inexpensive.
You either purchase or make the mixture yourself.
Should you opt for the latter approach, bear in mind that improperly computed ratios will yield subpar outcomes: a composition with a high fat content (high quantity of binder) might start to crack after drying.Plastering window slopes with a composition like that will be pointless because there won’t be enough fat in it, and you’ll have to redo all the work very soon. Avoid preparing too many solutions at once. It will become harder after an hour if you don’t use it. You must consider the fact that the gypsum mixture dries considerably more quickly than cement when selecting a solution.
A well-mixed plaster will slightly adhere to the spatula.
Preparing the surface
You must shut the window block first. The best method for doing this is to cover the window sill with a film and use construction tape. PVC windows need to have their side opening surfaces cleaned and leveled. Additionally, earlier plaster layers must be removed. Tapping on both sides will cause the old mixture to come off. Using a construction knife to assist oneself is convenient in this situation.
After being treated with a hydrochloric acid solution, brick walls are cleaned with water. If oil stains are present, you must apply fat clay to them, allow it to dry, and then rinse with water.
Using a deep penetration primer improves the composition’s ability to adhere to the surface. To ensure that the work is completed evenly, install beacons next. Here, visual perception is of no use. Plastering the slopes is done strictly according to the guidelines. The primer needs to thoroughly dry.
Insulation and soundproofing of the slope
You can greatly increase the apartment’s thermal insulation by using your hands to plaster plastic windows according to the proper technique. In order to complete it effectively, keep in mind:
It will be appropriate to use more hermetic, dense materials from the inside of the room and more porous, heat-insulating materials closer to the exterior.
This helps to prevent condensation by creating ventilation within the insulation.
The type of window seals and sealant used is just as important to the quality of sound insulation as the double-glazed window’s design. More elastic materials will have a higher sound absorption rate.
Today’s market offers a vast array of insulation materials, including foamed polyethylene and polyurethane foam.
After installing plastic windows, plastering slopes is a crucial step in finishing the window installation process. It guarantees that the window will appear completed and will mix in perfectly with the surrounding wall. Furthermore, slopes with good plastering provide better insulation, preventing moisture and drafts from entering your house.
A polished finish can be achieved by taking the time to thoroughly prepare the surface and apply the plaster evenly. It is possible for anyone to create sturdy and smooth slopes that improve the look and feel of windows with the correct equipment and supplies.
All things considered, plastering the slopes surrounding your plastic windows correctly is an investment that pays off in terms of both energy efficiency and aesthetics. You can make sure your windows look great and function well over time by following these steps.
