Grit blasting involves the propulsion of abrasive material at a surface, with the aim of preparing it for NDT, repainting, resealing, or coating. The abrasives remove stains, scaling, rust and old coats of paint. Below are some benefits which make grit blasting the ultimate method of surface preparation:
1) Eliminates The Need For Chemicals
The main principle behind grit blasting is abrasion, requiring no use of chemicals. Acids and other chemicals pose a danger to the environment and are more difficult to dispose of than abrasive material. Chemicals are also more costly as they cannot be easily recycled.
2) Provides A Better Bond
Grit blasting prepares the surface for painting or coating not only by removing contaminants but also by providing the optimal conditions for the new paint to adhere to the surface. As opposed to chemical cleaning, grit blasting does not alter the chemical composition of the surface, which could lead to difficulty in bonding between the coating and the surface.
3) Allows Consistent Profiling
As a surface preparation technique, grit blasting offers the added advantage of allowing the creation of profiling when blasting. The surface being prepared can be accurately modified by selection of the most appropriate abrasive material.
4) A Cleaner Surface
Grit blasting – especially wet grit blasting – aids the removal of soluble corrosion salts and other hidden contaminants. This reduces the potential expense of additional post blast cleaning by other methods, making the process more efficient.
