XTROWEL represents an important goal in the development of new products, designed according to the real needs of users. The need to avoid black streaks on applied materials, especially in light or white colors, at the time of polishing, led to the search for a new type of steel that the Marmorino Tools brand has obtained in exclusive use. The particular formula of this steel subjects the materials to a very low friction thus avoiding “burns” or streaks and the blade is minimally damaged by the particles of the decorative materials, resisting even the roughest stuff. It is therefore recommended for microcement, resins and for polishing the stucco.
