The Green Umbrella GHP Process: Steps Towards Achieving a Ground, Honed and Polished (GHP) Floor

Polishing a floor is more than just opening the concrete and applying an acrylic sealer! The Green Umbrella GHP process is the art of mechanically and chemically processing a concrete floor through a series of grinding, honing and polishing techniques to produce a reflective surface.

Substrate Prep

Includes the removal of any floor coatings, tile, carpet, mastics, glue, etc.


The concrete is opened up and surface blemishes removed using heavy duty grinding machines equipped with bonded, impregnated discs. Additional floor flattening may occur as well.


A variety of concrete treatments may be applied to dust-proof, seal out potential contaminants, provide abrasion resistance, repel salts, oils, etc.


Using grinders and a bonded tool that mechanically produces a matte appearance and a slight clarity of reflection.

Penetrating Colorants

When desired, colorants may be introduced to a properly opened concrete substrate. Some colorants are better when multiple colors are desired. Others in outdoor environments.


Last step in the mechanically processing of the floor that produces a clarity of reflection like a mirror and has a glass-like finish.

Penetrating Microfilm

A concrete treatment may be applied to protect against foreign contaminants, oils, acids, etc.

Make sure your spec contains:

  • Equipment-Must have production rates that will not impede other trade schedules
  • Abrasives– The Cut is as critical as the Treatments
  • Treatments– Hardener, Color, Microfilm
