Roof Parapet Paint Removal by Blast Cleaning
Commercial
- Surface and material
- Concrete roof parapet
- Existing condition
- Failed, flaking paint coating across the full length of the parapet.
- The problem
- The existing coating had lost adhesion and could not be overpainted — any new system applied over it would have failed with it.
- Method used
- Abrasive blast cleaning at a pressure matched to the concrete substrate.
- Work completed
- Surrounding roof surfaces protected, coating stripped back to bare concrete, spent abrasive and coating debris collected for disposal.
- Result
- Clean, keyed concrete parapet handed over ready for a new coating system.
