From the street, door and window openings can be plastered with cement mortar. This type of finishing is very cheap in terms of material costs, but allows you to simply transform the facade. Such work at first glance looks complicated, but it can be done with your own hands if you follow the plaster correctly: cement M400; the process of framing openings with plaster. To work, you need to prepare thick plaster. To do this, add cement and sand in a ratio of 1:3. Everything is mixed dry, then 0.5 parts of water are poured in. While it is being mixed, it is added little by little until the thickness of the plaster is optimal. To make a frame around the opening, it is necessary to apply a thick layer of plaster to the required width on the wall. You need to adjust the thickness of the solution using rulers or even wooden slats. The latter stick very well to the plaster. You need to attach 2 slats to each side on either side of the frame line. Then the solution is poured between them and smoothed. It is necessary to create a plane between the light rays. Then clean, dry cement is rubbed into the plaster. It will strengthen the surface, make it harder and more resistant to moisture. It will be like concrete. The cement will immediately absorb water from the plaster and become wet, so it can be easily ground. You can create a perfect plane by making a wide hole in the slats. Then you will have to pull out the side surface of the frame. To do this, the slats are removed. One of them is applied flush with the edge of the front smooth side. Plaster is then applied to the side wall, followed by dry cement and smoothed. After removing the planes, you need to smooth everything out again, applying a lath so that the tool does not press into the plaster more than necessary. Finally, decorative slots can be made on the frame. To do this, apply a lath, and cut the plaster along it, as a rule, with a thin trowel or other suitable tools. Then you need to let the plaster dry. If necessary, it must be protected from direct sunlight. After the frame has dried, you can paint the facade. If there are any defects, they can be easily sanded when the solution dries a little.
