Green Umbrella Applicator

Green Umbrella has three different levels of certification offered to meet your needs. A GU Applicator is trained and certified to use our concrete treatments for an earth-friendly concrete floor. An applicator applying our product may not have our equipment because it is unnecessary to apply our concrete treatments.

Green Umbrella Craftsman

The next level is a GU Craftsman. In addition to using our concrete treatments, the craftsman uses our abrasive mechanical process and Green Umbrella propane-fueled equipment.

Green Umbrella Master Craftsman

A GU Master Craftsman combines concrete polishing skills with the ability to place and finish new concrete.


The Process for Abrasive Polishing

A Green Umbrella Craftsman supports the industry standard of The Green Polishing 9, the nine fundamentals that have several advantages. A green mechanical system includes processing the floor wet to avoid silicosis issues, which could endanger installers and future inhabitants by contaminating air ducts in the building. The GP9 process uses a progression of abrasive grits on a machine built for wet concrete processing. Using water with a liquid cutting agent enables a higher-quality cut. The wet grinding system has been well supported in the industry for the best finish to a floor. It keeps a project OSHA compliant, preventing the use of inadequate vacuum systems and violations of health safety standards often encountered when using other methods.

The Process for Integrally Troweled Floors

A Green Umbrella Master Craftsman uses best concrete practices to place and finish concrete. Possibly certified by standard organizations, such as the American Concrete Institute or American Society of Concrete Contractors, that provide both guides and certification to assure the craftsman is trained in procedures accepted in the industry.
