Sandblasting and power washing are both methods of cleaning surfaces, but they use different techniques and are suitable for different types of cleaning tasks.
Sandblasting uses a high-pressure stream of abrasive material, such as sand, to blast away dirt, grime, and other unwanted materials from a surface. This method is typically used for heavy-duty cleaning tasks, such as removing rust or paint from metal surfaces, cleaning stone or brick surfaces, or preparing surfaces for painting or coating.
Power washing, on the other hand, uses high-pressure water to blast away dirt and grime. It's commonly used for cleaning exterior surfaces such as decks, sidewalks, driveways, and building exteriors. Power washing is less abrasive than sandblasting and is often used to clean surfaces that have been previously painted or coated, as well as surfaces that are not suitable for sandblasting such as wood and plastics.
Sandblasting is more abrasive, uses abrasive materials and is suitable for heavy-duty cleaning tasks while Power washing uses high-pressure water and is suitable for cleaning surfaces that are not suitable for sandblasting.
In summary, Sandblasting is a more heavy-duty method and typically used for larger surfaces, while conventional sanding is used for more precise or detailed work, and it is mainly used for woodworking and metalworking.
