Get Concrete Sandblasting QuotesThe Finish Decides the Method
| Goal | Common method |
|---|---|
| Clean dirt, mould or staining | Pressure washing, sometimes light blasting |
| Remove paint or old coatings | Abrasive blasting or grinding |
| Prepare a floor for epoxy | Shot blasting or diamond grinding |
| Light texture or anti-slip | Light abrasive blasting |
| Exposed aggregate or deeper texture | Heavier blasting to the agreed depth |
| Pool shell before resurfacing | Abrasive blasting to remove old coating |
Surface Preparation for Coatings
Epoxy and polyurethane coatings need a clean, open surface to bond. Laitance (the weak top skin), oil and old coatings have to go. Coating suppliers often specify a surface profile, and the contractor should prepare to it.
Limitations and Preparation
- Blasting opens the surface and exposes stone, so the look changes. Do a sample area.
- Oil soaked into concrete may need degreasing first or will stop coatings bonding.
- Dust is heavy. Indoor floors usually need vacuum-recovery equipment rather than open blasting.
- Weak or damaged concrete may need repair before any coating.
- Cracks and joints show up more after blasting.

Frequently Asked Questions
Is concrete sandblasting the same as shot blasting floors?
Both prepare concrete. Floor shot blasters throw steel shot and vacuum it back up, which suits large indoor floors. Open abrasive blasting suits walls, pools and outdoor areas.
Can paint be removed from a concrete driveway?
Usually, by blasting or grinding. Some paint stains remain in the pores. A small test area shows the result.
Will blasting make concrete rougher?
Yes. The depth is controlled from a light etch to exposed stone. Agree the texture with a sample first.
Do I need blasting before epoxy flooring?
The floor needs a clean, profiled surface. Shot blasting or diamond grinding is standard. Painting over unprepared concrete risks peeling.
Can pool shells be sandblasted?
Yes, it is common before resurfacing or recoating a pool. The pool must be drained and the debris removed.
