What is one of the primary risks associated with sand blasting?

Sand blasting, while an effective method for removing paint and contaminants from surfaces, carries certain risks, one of which involves the potential to scratch glass and moldings. During the sand blasting process, abrasive materials are propelled at high speeds, which can lead to unintentional damage on sensitive surfaces like glass and decorative moldings.

The impact of the abrasive particles can create micro-scratches on glass, impairing visibility and possibly requiring replacement or repair. Similarly, moldings, which may have delicate finishes or be made from softer materials, can be easily damaged, leading to costly repairs or replacements.

Understanding this risk is crucial for painters and refinishing specialists, as it emphasizes the need for careful masking and protection of areas that should not be exposed to the blasting process. While sand blasting does improve surface preparation for paint adhesion, it should be executed with great caution to prevent damage to surrounding components.
