FAQ
Frequently Asked Questions
No. Pressure washing uses high-pressure water. Sandblasting (abrasive blasting) uses a stream of abrasive material like sand propelled by air or steam to erode the surface, which is much more aggressive for removing coatings or rust.
Yes, metaphorically. It can describe a forceful, abrasive action that strips away superficial layers, such as harsh criticism sandblasting someone's reputation or a revealing documentary sandblasting the truth about an event.
It is most commonly used as a transitive verb (e.g., 'to sandblast a wall'). It can also be a noun referring to the machine or the process (e.g., 'The sandblast took two days').
Less commonly now due to health risks (silica dust). Modern abrasive blasting often uses safer materials like steel grit, glass beads, crushed walnut shells, or synthetic abrasives, though the general process is still often called sandblasting.
