Newgrind Inc. is backed with the knowledge of Owen Rogers, who has over 30 years of hands-on experience. With the development of the Rhino RL450, Newgrind Inc. can facilitate the removal of coatings and all types of glues and mastics and then grind, polish, color, densify and seal any concrete floor that is a candidate for polishing. Prepping for coatings and overlays is a dream when using the RHINO along with our superior 100% German tooling.
