Polerowanie betonu kątówką na sucho miedzianymi padami polerskimi. Jak szlifować podłogę betonową?

In this video, you'll learn how to grind and polish a concrete floor using a small angle grinder. The video describes how and what to use to renovate a concrete floor, dry grinding it with a diamond disc and copper scratch removal pads. The procedure is similar for renovating stone or terrazzo stairs. We begin with grinding it with a diamond cup wheel. After leveling the concrete floor, we move on to the actual polishing. This process is performed using copper pads attached with Velcro. We polish the floor successively using 30, 50, 100, 200, and 400 grit. When working dry, we don't need to use water jetting, but tests show that it's more effective. You'll find out in the next video.
