This conditioning pad is used to finish refractory surfaces after initial aggressive grinding. Its purpose is to create a smooth, level face on bricks and castable linings, which ensures a tight fit and minimizes joint gaps during installation. The pad uses a fine abrasive grit to remove imperfections without taking off excess material, and its semi-flexible design follows surface contours. It is the ideal tool for fettling bricks and for final preparation of refractory surfaces.
