Choose putty, depending on how you will decorate the walls: to paint or hang wallpaper. In the first case, select Uniflot putty from the company Knauf or Vetonit. It is more flexible and after drying it does not appear in the cracks.
If you want to paste over the wall wallpaper, then stop your choice on a budget option, as small cracks that may occur as a result of work still disappear under the wallpaper.
Prepare putty. Pour dry mixture in a bucket (or other container). Add water (according to the manual) and stir using a mixer. Finished plaster should be the consistency of thick cream, with no lumps.
To seal the inner corner, type filler at the end of a spatula and spread it along the seam and along one side of the angle. Then do the same along the second side.
Cut a piece of ribbon-serpyanku and fold it in half. Press the tape to the right, press it lightly. Once the composition is dry, apply another layer of filler on each side of the angle.
To seal the outer corners, attach aluminum perforirvanny Area, attaching it with screws. If the load on a small angle, for example, the angles of slopes in the window, it is possible to strengthen the ledges ribbon. It has an aluminum insert and a notch on the shaft. With this notch the tape easy to bend in half.
Apply plaster trowel first on one side of the angle and then - on the other. After the first coat has dried, apply another.
When the plaster has hardened, sand the surface with sandpaper. Then you can proceed to the application of top coat on the surface of the walls.
