A high-build, two-component epoxy filler designed for filling and leveling cracks and surface irregularities prior to the application of epoxy or polyurethane coating systems. It offers high hardness and excellent adhesion to a wide range of substrates, including concrete, steel, wood, and masonry surfaces. The filler provides a smooth, matt finish in white or gray, with good resistance to abrasion and chemical exposure. Suitable for both interior and exterior applications, particularly in flooring preparation works before final coating.
