Analysis of Polishing and Maintenance Techniques for Terrazzo

Shanghai Jiani Material Technology Co., Ltd. is a professional company specializing in the production of stone tiles.

Traditional terrazzo boasts unique advantages such as low cost, customizable color matching and pattern splicing, and convenient construction. It enjoys a huge market in China, with over one hundred trillion square meters of terrazzo flooring installed in various buildings across urban and rural areas nationwide. However, traditional construction techniques leave terrazzo floors extremely rough and prone to dirt accumulation. Many become stained and unsightly even before official occupancy, creating major obstacles for daily sanitation maintenance and termite prevention.

Over time, prominent problems have emerged in practical use: terrazzo surfaces suffer from weathering, abrasion, stubborn stains and a dull, lusterless appearance. Nearly five billion square meters of various terrazzo flooring have been laid in buildings across China. Restoring the original bright and aesthetic appeal of weathered and abraded terrazzo has become an increasingly urgent issue for the architectural decoration industry.

Currently, the only solution adopted at home and abroad for weathered and abraded terrazzo is to clean surface dirt and then apply a layer of wax. This method offers a certain protective effect on new terrazzo surfaces and slows down natural weathering and abrasion. Yet for already weathered and worn terrazzo, the effect is no different from applying varnish to rotting wood, failing completely to restore a mirror-like gloss. Moreover, the wax film formed has poor durability, usually lasting only about a week before re-waxing is required. Frequent reapplication leads to high costs, and waxing provides neither temporary relief nor a fundamental solution.

Waxing is not a genuine stone floor treatment method because it fails to address the core technical problem of terrazzo maintenance. The mirror-like shine and crystal clarity of terrazzo stem from a vitreous film formed on its surface after mechanical processing. This film delivers mirror luster and transparently reveals the internal texture and natural patterns of the stone — the very source of its aesthetic charm. The key to restoring the beauty of weathered and abraded terrazzo lies in reforming this vitreous film on the surface.

To rebuild a protective film on terrazzo flooring, professional grinding and polishing treatment is required. A terrazzo floor grinder and polisher is used to remove the weathered and abraded aged surface layer, exposing the fresh inner layer. A specialized mechanical process then triggers complex physical reactions on the terrazzo surface to form a new vitreous film, restoring its natural bright decorative effect. The entire process involves multiple procedures without the use of any chemical agents. It fundamentally renovates rough, dirty terrazzo into a smooth, mirror-finished surface, delivering both symptomatic and permanent solutions.
