When to Use
Compared to sanding by hand, sandblasting is much less laborious when you need to remove paint from a large area. It is also the method of choice to remove paint from objects with many nooks and crannies that would be impossible or very difficult to remove by sanding.
What to Sandblast
Sandblasting can be used to remove paint from any object that will hold up to the intense abrading force of sandblasting. Brick, concrete and metal surfaces generally fall into this category.
