Sponge Blasting

What Is Sponge Blasting?

From delicate cleaning to aggressive coating removal, Sponge Blasting provides an almost dust-free solution to sand blasting. Using closed-cell urethane sponge granules which contain an abrasive aluminium oxide, it is a dry, safe and low-dust process to strip exterior paint or create a profile on a steel surface.

How Does Sponge Blasting Work?

  • Compressed air propels sponge media to the surface.
  • Upon impact, sponge media absorbs collision energy and flattens on the surface. When the abrasive aluminium oxide is exposed to the surface, the contaminants are removed. The coating is removed, leaving the required profile on the substrate.
  • The sponge media entraps most airborne dust.
  • Sponge media contains different sizes and grades of abrasives for use on various surfaces.
  • Dry Ice International’s professional blasting technicians will carefully select the best sponge media to comply with client–specific requirements.
  • Air requirements: 11.35 m3/minute (400 cubic feet per minute) at 7 bar (100 psi).

Power Stations and Sub Stations

Power stations require a non-conductive, environmentally responsible cleaning process which allows for equipment to be cleaned in-situ.

General Maintenance

Removing rust on steel surfaces creates a desired profile prior to the application of paint.

Vehicle Restoration and Panel Beaters

Removing rust prepares steel surfaces for painting of bodywork.

Civil Engineering

Removing process stains, graffiti, environmental pollutants and soot from concrete buildings, bridges and other structures means sponge blasting is an excellent method for cleaning building façades and for interior refurbishing.


Aircraft maintenance specialists use sponge blasting to remove paint coatings, layer-by-layer, without damaging sensitive metallic or composite substrates.

Nuclear Power Generation; Reactor Coolant Piping and Turbine Rotors

Ideal for nuclear decontamination and general industrial coating and rust removal.

  • Low dust emissions.
  • Low ricochet and clear visibility.
  • Reduced need for dust suppression and on-site dust extraction.
  • Greater operator safety – low abrasive rebound, low dust.
  • Dry surface preparation.
  • Enhanced surface cleaning and chloride removal from steel.
  • The option to create a surface profile of 5-100 microns on steel.
  • Replace mechanical cleaning tools for faster and easier treatment of curved surfaces with a near-perfect finish.
  • The process is dry and non-conductive, and therefore suitable for use on electric motors and electrical circuitry.
  • The sponge media is 95% recyclable, providing the following benefits:.
    • Reduced waste
    • Simplified clean-up procedures
    • Simplified clean-up procedures
    • Reduced impact on the environment
    • Reduced waste disposal

Industrial Painting

What Is Industrial Painting?

Dry Ice International has provided award-winning solutions streamlining the dry ice industry. Dry Ice International is the market leader in dry ice products and dry ice blasting solutions in South Africa. According to a recent market survey, the proven capabilities and scale of our production solutions, support operations and reliability have positioned Dry Ice International for continued success in the future.

It’s the application of surface covering: preserving, protecting and functionally enhancing untreated and treated surfaces and structures including all required pretreatments. Industrial paint has two purposes:

  • Provides a protective coating against chemical and physical attack
  • Gives the product a pleasant appearance that increases its value

Industrial painting considerably extends the life of objects and buildings. It contributes to the reliability, safety and availability of the painted surface and serves sustainability and the environment in general. Preparation is usually the key to long lasting applications. The process tends to be easier if paint was not applied previously, otherwise a removal of the existing coat is required, making use of sand, sponge or dry ice blasting.

Industrial paint can be used to protect metal, wood, and a variety of other materials and surfaces. Various characteristics depend on the ingredients of the paint and the performance specifications of the selected application. Application methods can also influence the quality of the paint coverage and determine how well paint will stick to the surface.

How Does Industrial Painting Work?

Industrial paint can be applied to various structures that can be aggressively cleaned. It is essential to blast before painting, because the removal of all rust is of supreme importance in providing a long-term corrosion resistance system.

Various paint systems may be used, including inorganic and organic zinc-rich primers and zinc phosphates, epoxies, epoxy tars, alkyds, acrylics, vinyl, enamels and polyurethanes.

Painting is done under cover to ensure that the blasted surface does not rust before painting. Blasted surfaces can begin to rust or become contaminated within 4 hours.

When surface preparation and painting is done outside, the clean steel starts to rust immediately, especially if humidity levels are high. 

Therefore painting needs to be done immediately after surface preparation in order for it to be successful and long lasting.

The overall quality of painting under cover is better due to less interference from the wind, dust, rain and general contamination from the environment. This ensures that the required thickness is accomplished within the necessary time span and that the paint dries without accumulation of dirt and dust in the coating.
