Specialist Coatings

Providing innovativecoating services 

Coatings and Rope Access with Specialist Painting Group and Cygnet Projects 

Specialist Painting Group is an international coatings contractor that began trading in 1997 as a UK, Peterborough based commercial painting company with two employees. SPG has become a well established, multi faceted company providing technical expertise to the industrial sector. Our company directly employs a specialist work force who operate across a diverse range of industries both off-site at our head office and painting facility in Peterborough and on-site across the UK and Europe. Today the company is run by three members of the Fallows family who are dedicated in their pursuit of excellence within an industry they have been involved in for many years.

High Density Co2 Blasting

Using frozen Carbon Dioxide pellets derived from high density liquid Co2 the blast medium sublimates and returns to a gaseous state upon impact. This sublimation results in no spent blast medium being created.
High Density Co2 blasting removes existing coating systems, corrosion products and surface contamination in three ways:
  • Velocity of High Density Co2 being propelled by compressed air
  • Thermal effect of the High Density Co2 impacting the existing coating system, corrosion products or surface contamination reducing the adhesion to the substrate
  • Expansion of the High Density Co2 sublimating to a gaseous state expanding to 800 times its original size results in lifting the existing coating system, corrosion products or surface contamination from the substrate
High density Co2 blasting is a controlled method of blast cleaning. The selection of the correct nozzles, rate of blast medium throughput and correct pressure are important elements of this unique application. The result is the complete removal of existing coating systems upto 15mm, corrosion products and surface soluble salts, exposing the original profile of the steel substrate.

The financial implications of using High Density Co2 are significant. The sublimation of the material means that no waste blast medium is produced during the process. Unlike traditional grit blasting methods, High Density Co2 can be used without the requirement for hazardous waste removal and grit extraction.

Productivity during a coating removal project is dramatically increased as the cleaning out process associated with grit blasting is eliminated. The exposure to operatives is reduced as hazardous waste in not being produced in the form of spent grit. The procedure is a non fatigue procedure resulting in reduced exposure to those undertaking the application.

High Density Co2 blasting has a reduced impact on the environment due to no hazardous waste being produced as part of the process. High Density Co2 is a more sustainable method of blast cleaning in comparison to traditional methods.
SPG works directly with the leading supplier of High Density Co2 and is the UK's approved contractor for this process of blast cleaning. We have extensive experience in the use of the application equipment and high density liquid Co2 processing machinery.
