Comparison of Waterblasting vs. Sandblasting

The preparation of the surface greatly influences the quality, effectiveness, and life span of a paint job. Coating adherence to the substrate depends on the surface being free of debris, including dust, grime, and grease.

Abrasive water blasting and sandblasting are two of the most common ways industrial painters prepare surfaces today.

Waterblasting

  • Cleaning various surfaces has never been easier or more cost-effective than water blasting. Listed below are the most significant advantages.
  • Waterblasting, unlike chemical-based cleaning, leaves no residue, eliminating the need for washing.
  • Waterblasting can clean and prepare a wide range of outdoor painted surfaces without the risk of releasing harmful toxins into the air.
  • Users may change the water pressure and swap fan nozzles to suit the task. This includes lowering the pressure to remove dust and cobwebs while increasing it to remove multi-layered adhesive coating systems, exposing cracks so that suitable repairs can be made, and opening the surface pores to deliver specific types for the implementation of modern protective coating systems.
  • Waterblasting cleaned surfaces are chemical-free and ready to reuse (once completely dry).

If you don’t do it the right way or use waterblasting equipment the wrong way, you could cause localized damage and severe erosion of surfaces.

Sandblasting

Even though sandblasting is most often used for metal, it can be used to clean dust, dirt, and old paint off of other surfaces as well.

Two methods of sandblasting are available. It is possible to utilize either wet sandblasting or dry sandblasting, both of which use high-powered streams of water combined with abrasive material to clean a surface. The following are the advantages of both methods:

  • Sandblasting is a better, simpler, and quicker method of cleaning and preparing various surfaces for painting than water blasting.
  • There are many different sandblasting settings that can be used to perform a variety of tasks, from light cleaning to more abrasive operations like removing grit or old paint.
  • Sandblasting is much more powerful than sandpapering, making it possible for professionals to prepare surfaces in hours rather than days.

To get metal ready for painting, sandblasting, pressure washing, or steam cleaning, are sometimes used together. Wet sandblasting, on the other hand, is less harmful since it doesn’t produce toxic dust clouds. Sandblasting projects in certain sections of Florida (e.g., Miami, Long Beach, and Coral Gables) need approval from the city or county.

There are a variety of factors to consider while undertaking a painting job.In order to determine which blasting method is best for a certain application, it is necessary to review the project parameters, substrate condition, technical data sheets, and application techniques.

When in doubt, it’s always a good idea to consult with specialists for guidance. More info on Vertidrive.com.
