A thing of beauty, concrete steps restored using a Milwaukee grinder. #milwaukee #tools #torginol
What happens here
A significant portion of the video demonstrates the crucial surface preparation phase. A worker, wearing comprehensive personal protective equipment including a respirator, earmuffs, and gloves, uses a hand-held concrete grinder to remove an old coating from concrete stairs. The grinder is fitted with a diamond grinding cup wheel and an attached dust shroud, which is connected to an industrial vacuum system. This setup effectively captures dust, ensuring a cleaner and safer working environment. The grinding creates a clean, rough profile on the concrete, which is essential for the proper adhesion of new epoxy coatings.
Goal: Remove old coatings and profile concrete for new epoxy application.
