  6. We make cutting.

Action algorithm:

  1. Measuring the corner of a room with a corner. The tool is applied in the corner compartment to the ceiling surface. The indicator must be equal to 90º. If there is a deviation, it can be argued that the angles are uneven, which means that cutting the plinth will be more difficult.
  2. Apply a ruler to the baseboard at an angle of 45º. With a sharp stationery knife with a sharp movement we cut off the unnecessary part. If we are talking about wooden plinth, then first make the markup with a pencil, and then perform cutting with a hacksaw.
  3. Verifying proper cutting: ceiling plinths are applied to the corner of the wall. If the work is done inaccurately or there are minor defects, then you can eliminate them with emery paper (unless the part turned out to be smaller than necessary).

In the presence of an uneven angle, it is necessary to measure its degree, and divide the resulting number by 2. As a result, we obtain the required value for cutting. For example, if there is an angle of 80º, the baseboard angles should be equal to 40º.

You can adjust the baseboard in place, in this case, follow the sequence of actions shown in the photo:
