Surface preparation is the key factor in determining the success of a protective coating system. The objective of surface preparation prior to applying a coating system is to create proper adhesion of the coating to the original surface.  Proper adhesion will occur, only if a suitable level of surface cleanliness and roughness (profile) is achieved.  

There are a wide variety of Surface Preparation methods available, such as Solvent Cleaning, Power-tool Cleaning, Dry Sand Blasting etc.  But, all these conventional methods are rarely used because they are time consuming, not cost effective & provide poor cleaning results & also create environmental pollution.

Nowadays, Water Sand Blasting by High Pressure WaterJet Pump has got wide acceptance in the field of surface preparation as well as in Paint Removal. Water Sand Blasting is a common procedure for removing paint and rust from steel or other metal surfaces. In this process, an abrasive material is mixed with the WaterJet to create an abrasive spray. This abrasive spray is blasted on the surface, which breaks away small pieces of undesirable coating corrosion or other undesirable substances to create the desired white metal finish, perfect for recoating.

Water Sand Blasting is widely used in various industries for different applications as it offers following advantages vis-à-vis other conventional methods.
 

ADVANTAGES

• Because of the water ingredient, it will not create any environmental pollution problem caused by fluttering the micro power.
  
  
• It can remove the burrs (surface projections) & scales formed on surface and clean the surface without damaging the work piece. 

• The surface finishing can access a homogeneous matte finish (spot pattern). It can contribute significantly to the finishing demand for surface roughness.

• It only applies small shot blasting effect to the surface to be finished and improve and reinforce the material of work piece.

• The foreign materials after being removed will be rinsed and flushed out by the jet of water.

• It doesn’t require any chemical during operation.

• It doesn’t affect the dimensions of the object.
