Clean and Fill Concrete Floor Joints and Cracks

In this video, a QuestMark commercial flooring professional demonstrates the process of cleaning and filling joints and cracks in a concrete floor. First, debris and dust are thoroughly vacuumed from the joints and cracks. Next, the joints and cracks are filled with flexible epoxy, creating a smooth surface. The epoxy is used because it allows the concrete slabs to move independently while maintaining sealed joints and cracks, preventing debris from entering those areas. Once the epoxy has dried, the surface is ready to be ground or polished, ensuring a seamless, durable finish.
