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 if a suitable level of surface cleanliness and roughness (profile) is achieved.

Wet Sand blasting is a common procedure for removing paint and rust from steel or other metal surfaces. As shown in the CD, with this procedure, a dry abrasive material or sand is mixed with the water jet to create an abrasive spray. This abrasive spray is blasted on the surface, which breaks away small piece of undesirable coating corrosion or other undesirable substances to create the desired white metal finish, perfect for recoating.

Nozzle used in wet sand blasting consists of an ejector, which works on the principle of venturimeter. As soon as high pressure water passes through this ejector, vacuum is created and to this vacuum portion taping is provided to a suitable source of sand. As a result of this suction, sand is sucked inside and at the end through the spraying nozzle an abrasive fluid comprising of water with sand passes with high velocity. To avoid excessive wear, discharge nozzle tip is made up of tungsten carbide.

applications of wet sand blasting

Wet sand blasting technology can be used for preparing surface prior to coating, for rust removal, de-burring, flash removal, etc. Please find below herewith list of some applications wherein this method can be used

Paint, grease and rust, corrosion, scale removal

Casting Cleaning

Paint removal from ship hull

Clean and peen precision parts

Clean areas not accessible to hand sanders

Produce and anchor pattern ideal for uniform finishing

Deburr and finish machined parts

Blend light scratches and tool marks

Deflash plastic and metal parts

Chewing gum removal

Stone & Marble Cleaning

Surface preparation of plates and other structures.

Laitance removal from concreter surface and walls.

Please note as herein we are using sand or other abrasive material along with high-pressure water, it will make the parent surface rough, degree of which depends upon the size of sand particles used. Hence one cannot use this method on any surface, which is already grounded or finished.

advantages of sand blasting over other conventional methods

Wet sand blasting is widely used in various industries for different applications as it offers following advantages vis-à-vis other conventional methods.

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) and scales formed on surface and clean the surface without damaging the working piece.

The surface finishing can access a homogeneous matter 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 affect the dimensions of the object.
