Our Mission

With Green Umbrella we have put together a complete system of treatments and equipment that work seamlessly together. This process can be as complete as the initial pour all the way to the polish.

About Green Umbrella

Environmentally-Friendly Concrete Treatments for Architects and General Contractors

A combination of industry-leading performance and environmentally sensitive chemistry, Green Umbrella products are rinse-free, quick to cure, and simple to maintain. For wet or dry grinding and polishing, the Green Umbrella line has you covered.

Green Umbrella has a system approach to concrete polishing. It can be as complete as from the concrete pour to the polish. The Green Umbrella process IS NOT opening the concrete and applying a sealer. The majority of Green Umbrella Treatments are 100 percent reactive; non-resinous polymer, and ph-neutral when possible. Green Umbrella chemistry will not resist color introduction or walk off, as is common with other chemistry.

Providing greater accountability, Green Umbrella Craftsmen are certified with in-depth training using Grinding, Honing and Polishing equipment designed for complete concrete processing that can expose aggregate (this is not janitorial equipment).

Wherever possible alternative fueled equipment is used; not electric, and does not require a 3 phase hook up. Unless specified, Green Umbrella installers will process the entire floor including any and all wall edges. The process is wet wherever possible, maintaining ambient air quality and ensuring no dust contaminates the HVAC system. We endorse this for better health and wet grinding enables a higher quality cut to the floor. Green Umbrella floors include accountability through onsite management.

Simply put, Green Umbrella products are safer for the environment, and a responsible alternative for professionals concerned about the ecological impact of densifiers and other polished concrete treatments. Unlike most traditional floor treatments, Green Umbrella products have a very low VOC content, minimal impact on indoor air quality, and create an ultra-hard surface that reduces maintenance frequency while significantly extending the life of polished concrete and masonry.

Green Umbrella: Industry Terms

GHP Floor

In commercial terms a “Polished Concrete” Floor.  However this term leaves no doubt that the floor is receiving a full mechanical process (not opening the concrete and applying a resinous polymer or Acrylic sealer). This includes all three steps; Grind, Hone and polishing the floor. You can learn more about the GHP process here.

GH Floor

This includes the first two steps of a “Polished Concrete” floor.  Grinding and Honing the floor may be used to mechanically open up the floor for the introduction of color or chemistry in the concrete. Often times this is recommended over chemical stripping of the floor to remove contaminants or sealers. This method is better for environment and does not leave dormant chemistry in the pours of the concrete.

Concrete Processing

The act of changing an existing concrete surface by means of a mechanical process that involves cutting and/or refining the surface to a desired finish.

Ground Concrete

Also the complete processing procedure as mentioned for Polished Concrete. Ground Concrete has a flat appearance with no, or very little reflection and sheen. Grinding Steps are the lower grit diamonds up to 50 grit.

Honed Concrete

Also the complete processing procedure as mentioned for polished concrete. Honed Concrete has a matte appearance and a slight clarity of reflection that has a low, medium, or high sheen depending on the final diamond grit used. Honing steps are those between 50 grit diamonds and 800 grit diamonds.

Polished Concrete

The processing of the concrete surface through means of a mechanical process that uses an abrasive medium where each step is refined to its purest possible form on a microscopic level from one progressively finer abrasive to the next until the desired level of “polish” is achieved. Polished Concrete has clarity of reflection like a mirror and has a glass-like finish. The clarity will depend on the final diamond grit. Polishing Steps are 800 grit and higher.

Clarity of Reflection

The degree of how crisp and clean the reflection of objects appear in the surface of the concrete. Clarity of reflections are categorized as Polished, Honed, and Ground.

Surface Cut

The degree to which the surface of the concrete is abraded. These cuts are defined as Surface Cream, Fine Aggregate, Medium Aggregate, and Large Aggregate.

Full & Maximum Refinement

When the abrasive has refined the surface to the degree to which it no longer cuts, or cuts very little under its current weight.
