How to Get the Most Out of Your Coating Through Water Blasting

Tuesday, March 19, 2013

A new coating can spruce up your business, impress customers and give employees a brighter outlook with an inviting work environment. Before slapping on a fresh coating, it’s essential to clean and adequately prepare the area in order for the coating to adhere. There are many forms of surface preparation and water blasting is a safe yet effective way to ensure a solid finish.

Water blasting is a form of pressure washing that removes surface material and contaminants by spraying highly pressurized water onto a hard surface. The surface could be asphalt, concrete or any metal that needs a coating.

Facts & Features:


  • Water blasting can remove several types of contaminants, rust, dirt and previous coatings from the area.
  • Common uses include removing paint from highways, runways, concrete or steel surfaces, even parking structures. Some use water blasting to remove gum, graffiti or pollution.
  • Improperly prepared surfaces impact both the integrity and endurance of the new surface coating. If the surface is not sufficiently arranged, coatings can completely fail to adhere.
  • The appropriate blasting method depends on material, environment, expected life of new coating and any contamination on the surface.
  • There are two types of water blasting, both cold and hot. Cold water blasting is typically cheaper, lighter and simpler but hot water blasting is usually faster and more powerful. Hot water can offset labor cost and be financially beneficial overall depending on the job. For example, if you would like to remove oil from concrete, you would need hot water blasting.

After the surface has been prepared, you will need a satisfactory coating. Coatings can protect concrete from rain and salt as well as create a smooth surface for industrial use. If you are looking for a contractor in California (more specifically Central or Southern California), Cor-Ray Painting Company has had extensive experience in hot, cold and steam water blasting. For example, they completed interior and exterior blasting on Eastgate Reservoir tanks for Walnut Valley Water. They are also a great resource for painting and coating needs or any other type of surface preparation. Call (562) 906-9770 or click here to find out more.
