Here is the way we remove sanded grout from a tiled floor. This technique takes a great while of time to perfect, so I wouldn’t suggest a beginner trying this at home. We typically remove grout this way a half dozen times per month, so we have a lot of practice at it. The Grout Pro also specializes in keeping the dust in your home to a minimum. We use hepa filters along with a vacuum system to capture about 75% of the dust.
When removing the grout utilizing grinders be sure to use gloves, safety glasses and ear protection at all times. As always, feel free to ask any questions you may have.
