An Overview Of The Sponge Blasting Method

By Misty Tyler


When you have a surface that needs to have dirt, paint, oil and grease or other coatings removed, you want a process that is effective, without costing a small fortune. Better yet, the product should not harm the environment. Ohio customers can make use of the sponge blasting method to clean and prep surfaces of all types. The cleaning product is a polyurethane which is impregnated with abrasive materials. The product is sprayed on the surface which needs attention. The cellular structure of the poly flattens out as it strikes the surface which exposes the abrasive material. The polyurethane then constricts so that it lifts the coating or contaminants from the surface. The poly media can be reused, so it is economical.

A common use of the method is to remove one or more layers of paint without harming the underlying surface. Other substances can be removed with the same method. The variable in each case is the type of sponge that is utilized. This makes the method ideal for eliminating materials that should not be allowed to become airborne. The media is collected and reused, so that it is economical and efficient in job after job.

Because of the design of the media and the abrasives, there won't be damage to the underlying surfaces. At the most gentle level, the product has very minimal abrasives included, so that the process won't hurt even delicate surfaces. No dust is released and the cleaning process doesn't incorporate water, so that it is suitable for indoor, as well as outdoor use. This makes the process suitable even for restoration of historic homes.

If you have surfaces which are deteriorated or contain multiple thick layers of coatings, the polyurethane which contains steel grit is the most effective product. It even removes layers of rust. It can be used to remove industrial coatings or linings for petrochemical tanks and tanker cars.

When you need to remove coatings in industries such as marine manufacturing, military installations, offshore locations, power generation plants and petrochemicals, sponge media which contains aluminum oxide as the abrasive material is the best choice. It is a powerful media, but will not destroy the underlying surface.

When there are sensitive surfaces under the tough coatings, an abrasive consisting of plastic chips is helpful. This media type will remove graffiti and other coatings from surfaces such as fiberglass, tile, composites and other exotic surfaces.

If the underlying material is valuable and has a layer of oil and grease, only a mild abrasive is required. Light abrasion is needed to remove smoke and soot from hard surfaces such as concrete or brick. A light abrasive action can also be effective when working around hoses and fittings, or when there are nooks and crannies which are difficult to reach by hand.

The major benefits of the media lie in its minimal airborne dust. The product is economical, since the sponge media is captured and can be reused. Clean up after the removal is reduced, thus causing minimal impact on employee productivity. There is no water involved in the application process, further reducing the mess and cleanup efforts.
