Media Blasting

Sponge-Blast is Fast, Clean, and Dry!

Sponge Blasting adds speed and decreases dust in the removal of paint and coatings when compared with more traditional preparation methods. This new technology offers PennFleet the ability to remove individual layers of coatings with no damage to the surface beneath.

Sponge-Blast technology is so advanced that we can remove finite layers of paint, grime, or other coverings without damage to the substrate beneath. This system is often used on historic buildings and homes, and is the industry choice when precision is required. Sponge-Blast is even safe for use around delicate control systems.

Other removal systems cause dangerous particulate emissions or fumes from chemicals, and make a big mess. Because the Sponge-Blast system uses a sponge abrasion method, your ability to use your business or home is unhindered. There is no moisture, harmful fumes, nor air quality concerns to contend with. The sponge media is recaptured for re-use so it is clean and environmentally friendly.

The Sponge-Blast Process
Sponge Media is an open-celled, water based polyurethane impregnated with abrasives. As a result it has several inherent cost, time and money saving benefits. The pliant nature of Sponge Media allows its particles to flatten on impact exposing the abrasive. After leaving the surface, the media constricts pulling and encapsulating what would normally have become airborne contaminants.

Sponge-Jet’s Sponge Blasting System™ consists of the Sponge-Jet Media Feed Units, Sponge-Jet Media Classifiers and a variety of different Sponge-Jet Sponge Media designed to offer a dry, low dust, low rebound, reusable abrasive or non-abrasive surface preparation system.

Sponge Media is poured into a Blast Feed Unit where it is mechanically stirred and fed into a rotating screw-auger port at the bottom of the pot. The auger entrains the sponge in a variable pressure air stream – and the air-media mix flows through a hose and venturi blast nozzle to impact the work surface at 15 to 100 mtrs (50 to 325 ft.) per second depending on the blast pressure. On impact with the surface the sponge particles compress and slide across the surface producing a scrubbing and cleaning action, more similar to a sanding effect eliminating the more harsh and dusty negative effects associated with conventional grit blasting. The abrasive particles remove the paint coating or corrosion products and the media rebounds at quite low velocity as the media converts the majority of its energy into work at the surface. For most projects a tarpaulin or light plastic sheeting around the work area will contain media for pick-up and recycling. The Sponge Blast media will generate less than 10% of the airborne dust levels normally experienced with conventional grit blasting medias. This is a key Health and Safety benefit when removing lead and chromate paints. The Media Feed Unit requires a 7 bar (100 psi) air supply – capable of supplying clean dry air at 6 to 10m3/min (210 to 353 cfm).

Other removal systems cause dangerous particulate emissions or fumes from chemicals, and make a big mess. Because the Sponge-Blast system uses a sponge abrasion method, your environment is virtually undisturbed. There is no moisture, harmful fumes, nor air quality concerns to contend with. The sponge media is recaptured for re-use so it is clean and environmentally friendly.

Applications

humveeVehicles
The technology behind our Sponge-Blast method is so powerful that even the United States Military uses it for surface preparation of their combat and general transport vehicles. The sponge blasting process can be used on such a wide array of surfaces, from heavy metal to fiberglass. From restoring a tractor trailer to prepping your high end sports car, Pennfleet’s Sponge-Blast technicians know how to professionally prepare the surface of your vehicle to provide years of durability and extend the life of your paint job.

 

Marine
boatWhether you own a yacht or a small fiberglass runabout, your boat is subjected to the harsh sun and a punishing marine environment. These factors age a boat and cause them to need to be refinished to extend their life. With the Sponge-Blast process, your boat can be removed from the water, stripped, painted, resealed, and returned to service in short order. Sponge media can remove marine coatings and create a less-than-one mil profile without damaging the base of the boat. Should you require the use of our mobile service, there is no need to worry about contaminating the aquatic environment. The sponge system does not cause particulates ricochet, and harmful airborne contaminants are not an issue.

When running a business, cleaning and repainting can have a costly consequences.

 

Sponge-Blast can help you meet the following goals:

  • Cost competitive
  • High-quality surface preparation in sensitive or confined areas
  • Dry process – Low dust and fugitive emissions
  • A solution for preparing surfaces near finished coatings, instruments, and equipment
  • Accelerating your surface prep and painting time
  • Less downtime
  • Coatings perform longer, saving maintenance costs

historic-homeHistorical Restorations
Sponge-Blast’s low dust, environmental cleaning, and micro abrasion technology is specified by architects, preservationists, and masonry professionals as the choice to precisely clean and remove surface contaminants from sensitive and ultra sensitive substrates – while protecting the surrounding environment.

In historical restoration the goal is to remove contaminants without risking damage to the surface and surrounding substrates. Water and chemicals can leave a mess. Traditional abrasion techniques can cut into surfaces. Alternatively, the sponge media in our process flattens on impact, exposing the banded abrasives, and dislodges the contaminants safely. The vacuum system recovers the sponges, then removes the contaminants from them, and reloads the sponges for continuous blasting.

Sponge blasting is a Smart Choice for:

  • Stone Ornaments
  • Balustrades
  • Columns
  • Walls
  • Stair Treads
  • Wrought and Cast Iron Decorations
  • Copper, Tin and Bronze
  • Granite, Marble, Terracotta and Sandstone.
  • Brick and Masonry Block
  • Concrete
Sponge Blasting is Superior Because:

  • Sponge media captures most of the dust without the use of water
  • It is controllable for precise cleaning and removing paint
  • The process allows for inspection and visibility during the blasting process
  • The sponges are recyclable and less wasteful than other methods
  • Is up to 20 times faster than wiping or using power tools
  • Technicians can selectively strip coatings and remove environmental pollutants without damage to the surface.
  • Equipment allows for precises control and flow of media at pressures from .1-7bar (2-100psi)
  • Damage from media ricochet is virtually eliminated
  • It allows for cleaning and grease removal without water or detergents
  • There is no chemical runoff or leachable constituents.
  • Fugitive emissions are reduced leaving the air and environment cleaner than with traditional abrasives.
