Bearing in mind the different categories of buyers, we recommend that you pay attention to the best, from our point of view, units.

1. For "state employees" - HYVST-A1. The most practical and efficient option for small volumes of work.

2. For mid-budget - Eibenstock ELS 225. For medium to large work sizes.

3. For premium class - Mirka Leros 950cv. A device with a high rotation speed (from the devices presented in the review) and excellent quality.

When using a sander, it is important to follow a number of rules.

1. The grinding process is accompanied by a high degree of dust formation... Therefore, work should be done in a respirator. If conditions permit, close windows to avoid drafts. Cleaning after the work process is best done with a vacuum cleaner.

2. It is more convenient to grind not in diffused light, but under the beam of a small spotlight - so all the imperfections on the walls or ceiling are better visible. At the same time, it is better to periodically change the angles of the backlight.

3. You should work on the imperfections of the walls graduallyusing smooth circular motions.

4. With significant processing areas use clippers with a larger disc area, e.g. 225 mm in diameter... This will significantly shorten the running time.

5. Telescopic handles are very convenient for grinding ceilings, some can be adjusted for themselves, in lengths 110-180 cm.

6. Some models provide special systems for collecting dust, then you don't have to clean up after work.
