Historic Plaster Ceiling Restoration
Historic Manufacturing Building, Downtown Los Angeles
Project Overview
417 South Hill Street, Downtown LA — formerly the Subway Terminal. Decorative plaster coffer ceiling severely damaged by years of water exposure and neglect.
The Challenge
- Multiple areas of complete plaster collapse; extensive holes throughout.
- Water contamination preventing new material bonding; historic coffer details requiring faithful reproduction.
Our Approach
- Primer coat applied to block residual water contamination before patching.
- Larger collapsed sections fully removed and replastered from substrate up.
- Smaller areas patched to match original profile and texture.
- Decorative ceiling and column elements molded and reinstalled to historic spec.
The Result
- Ceiling returned to original grandeur — coffer patterns and column details faithfully reproduced for long-term durability.
