Materials and tools
You need to use professional power tools and high-quality building materials to get reliable concrete window sills. A collection of different tools to make a window sill:
- construction vacuum cleaner;
- Bulgarian;
- drill, screwdriver;
- laser level;
- putty, spatula, masking paper.
- wooden structures of various widths and lengths for formwork;
- metal grid;
- roulette;
- screws and other fasteners.
Nitro enamel or colored varnish is used for decorative purposes and to protect linings from damage such as chips, scratches, and other abrasions.
Surface preparation
The window sill component is cleaned and prepared prior to manufacturing. A 6 cm-wide recess is made for the panel on the front of the wall and along the slope in case the installation is done after the slopes have been plastered. They are carried out beneath what are known as windowsill ears.
The corner is cut to match the window block’s bottom in terms of height. The dimensions are transferred to the outer corner, the laser is installed, and the distance between the bottom of the window block and the red line the device produces is measured.
When constructing concrete window sills, it’s critical to seize this opportunity. This is done to ensure that, following structure installation, there is no poor alignment of the outer corner between the wall and the slope.
The measurement of the distance between the infrared beam and the window frame is depicted in the first image. The second demonstrates that an identical action is carried out with respect to the outer corner. Notably, the distance should always be the same—7.2 cm, for example—both here and there.
Dust, debris, and dirt are removed from the window sill following excavation and processing of the outer corner. Brooms and brushes don’t work. Vacuum cleaners are used for cleaning. This marks the end of the working surface preparation process.
Installation of window sill boards
You can construct a high-quality concrete window sill yourself in two different ways. The window sill board is cast separately in the first instance. In the second, it is produced right away on the spot. The final option provides a comprehensive solution to the problem of how to make a concrete window sill.
What makes up a window sill:
- formwork;
- cement mortar;
- metal grid;
- power tools and connecting elements (screws, bolts).
Creating a concrete window sill by hand starts with the formwork. It is advised to construct a window sill form for the purpose of pouring concrete on the location. This is the best option if you want to install a concrete windowsill yourself quickly and for the least amount of money.
Writing
The future product’s width and length are measured in order to manufacture formwork. For instance, at 17 cm, the board’s width and height should be 2-3 and 4 cm, respectively. This will suffice to make the windowsill standard in size.
Using a drill and a screwdriver, self-tapping screws are used to join wooden structures.
A completed design is displayed next to the work area in the figure below. The window sill in the picture of the open type makes a difference.
Dust, debris, and dirt are removed from the window sill following excavation and processing of the outer corner. Brooms and brushes don’t work. Vacuum cleaners are used for cleaning. This marks the end of the working surface preparation process.
The formwork from the inside of the window sill is visible in the picture. The completed structure for pouring a window sill indoors should resemble this.
Formwork installation involves the use of iron fixing elements. They let you install the product safely.
Each element has two holes drilled for self-tapping screws to be used when putting in formwork at the bottom. A screwdriver and screws (used ones are acceptable) are needed for the task. This is how the completed formwork appears:.
This is how self-tapping screws are used to secure the formwork from below.
More structures are nailed to the sides to stop the cement mortar from leaking out. The formwork production is now finished.
Preparing the surface for pouring cement
A design with the necessary width is created after the window sill area has been cleared of any mesh. It’s essential for premium filling. folds in half and has wires fastened for dependability. After being lowered into a brick hole, each wire segment is fastened to the mesh.
Use silicone if there are spaces between the window sill and the formwork. It will assist in preventing solution leakage.
Cement mortar
The mixture is made with crushed stone, sand, and cement. The solution’s ratio is one to two, or one hour of cement to two hours of sand. Utilizing concrete grade 400 is advised. There shouldn’t be much thickness in the final mass.
The solution is prepared and then poured in, first filling the gaps in the brickwork.
This is the image you should see after filling out.
The surface is then left until it dries completely. After that, overlays are applied, the surface is polished, and decorative processing is done.
Decorative treatment of window sill
Using a spatula, remove any protrusions, rough spots, and drooping areas after the surface has dried. The window sill after drying is seen in the picture below.
The last step is to level the surface with putty (either ready-made acrylic or gypsum). At least two layers make up the composition. The achievement of a smooth final surface is crucial.
Using fine sandpaper, the surface is smoothed out once the putty has dried. The window sill is then cleared of dust, and primer is reapplied.
The picture displays a perfectly level surface.
The surface is painted after the last drying process. Consider using water-based or light-colored enamel; neither has a strong smell. Painting is done using a brush or narrow roller in multiple layers.
Step | Description |
1. Gather Materials | Get concrete mix, water, a mold, and tools like a trowel and sandpaper. |
2. Prepare the Mold | Create a mold the size of your window sill using wood or plastic. |
3. Mix the Concrete | Follow the instructions on the concrete mix package to prepare the concrete. |
4. Pour the Concrete | Fill the mold with the concrete mix, making sure it"s evenly spread. |
5. Smooth the Surface | Use a trowel to smooth the surface of the concrete and remove any air bubbles. |
6. Let it Cure | Allow the concrete to cure for the time specified on the package, usually a few days. |
7. Remove the Mold | Carefully take off the mold once the concrete is fully cured. |
8. Finish the Surface | Sand the edges and surface for a smooth finish, and apply sealant if desired. |
