Grit blasting and shot blasting are excellent methods for surface preparation. Either use of material, fired at an extreme speed, can prepare a surface to either be resealed or repainted. This is a fantastic way of removing stains, rust, old coats of paint and scaling which no longer keep vibrancy.
There are numerous advantages to choose grit blasting for surface preparation over the other techniques that can be used, this article will explain why people use this technique.
Because the key principle involved with shot and grit blasting is abrasion there is no better alternative. Other methods would involve acids and chemicals which are harmful to the environment and difficult to dispose.
With shot and grit blasting, the results are identical but with pellets and dust to clean up and materials such as these are often recycled, resulting in very little wastage involved. It is vital to keep in mind that although both chemicals and blasting do the same job, chemicals that are used could impact the surface and any new coating applied.
Better Potential Bond
Along with the above point, the bond of the surface once it has been cleaned up is extremely important. Because grit and shot blasting is more of a natural technique, it will allow any new paint or seal to take better hold. It the surface is cleaned with chemicals, the bond between the coating and surface may not be as strong.
Accuracy for Patterning
With a wider range of abrasive materials and the choice for greater accuracy in blasting, you are able to create patterns when blasting – this is something that is harder to accomplish with other techniques.
No Dust on Your Surface
Using grit or shot blasting means that there will be no dust or scaling left behind on your surface, you will end up with a cleaner surface. In addition, you will not need to wash the surface of chemicals because there is none used in the process.
For a long-term solution, you can do no better for the surface than to apply abrasive blasting. This is the eco-friendly, accurate and residue-free technique, resulting in the potential to last a longer time.
