Simiron Polygrout is a patented, two-component hybrid polyurea/polyurethane pore filler engineered to enhance the performance and appearance of polished concrete and terrazzo flooring systems. Designed specifically for the concrete polishing process, Polygrout permanently fills pores, pinholes, pitting, scratches, cracks, and surface voids to create a denser, smoother surface capable of achieving higher gloss and improved depth of image. Unlike traditional inorganic densifiers that rely solely on chemical reactions within the concrete, Polygrout physically fills surface imperfections while creating permanent densification that will not break down over time. The result is a more uniform polishing surface, improved reflection clarity, and a professional finished floor.
