Project Overview
This project involved the specialized coating and restoration of marine downstand walls at the Natural History Museum Abu Dhabi. The objective was to achieve a consistent color match with existing planters while providing a high-performance protective coating system to withstand harsh marine conditions. The works were executed in line with industry best practices to enhance durability, aesthetics, and long-term performance of exposed marine structures.
- Total Downstand Area (Walls): 1,611 sqm
- Optional Tunnel Areas (as applicable): up to 1,065 sqm
- Environment: Coastal / Marine Exposure
Project Objectives
- Achieve uniform color integration with surrounding architectural elements
- Protect concrete surfaces from saltwater, humidity, and environmental exposure
- Restore and prepare substrates for long-lasting coating performance
- Deliver a consistent, high-quality finish across all downstand surfaces
Scope of Work
1. Surface Inspection & Preparation
- Comprehensive inspection of all downstand surfaces to assess coating condition
- Identification of defects, deterioration, and surface irregularities
- Removal of salts, mineral deposits, marine growth, oils, and grease
- Surface preparation using abrasive blasting and mechanical methods
- Execution of concrete repairs to achieve a uniform and continuous substrate
- Treatment of all joints to ensure seamless color matching
2. Joint & Surface Integration
- Coating of all joints to ensure visual and tonal continuity across surfaces
- No filler applied, maintaining structural integrity while achieving uniform finish
3. Quality Assurance & Compliance
- Continuous monitoring throughout all stages of coating application
- Adhesion testing to verify coating performance and bonding
- Inspection for defects such as runs, uneven finishes, or surface inconsistencies
- Use of certified equipment with regular third-party inspection
4. Health, Safety & Environmental
- All personnel equipped with appropriate PPE
- Certified marine access operations including trained personnel
- Emergency response plan and vessel in place
- Tools secured with lanyards to prevent marine contamination
Coating System
Application of a marine-grade protective coating system, specifically selected for durability in coastal environments:
- Application of primer coat to enhance adhesion and corrosion resistance
- Application of intermediate coats to achieve required thickness and coverage
- Application of final topcoat to deliver a uniform finish, consistent color integration, and long-term protection
Technical Highlights
- Extensive downstand coverage requiring specialized high-reach and marine access execution
- Integration of finish with adjacent architectural planter elements
- Maintenance of original structural form without utilizing fillers
- Execution strictly following approved method statements and best practices
Challenges & Solutions
Achieving consistent coating performance and appearance across large and varied downstand surfaces
Systematic surface preparation, controlled application processes, and rigorous quality checks ensured uniformity and durability
Operating within a marine environment with safety and access constraints
Implementation of strict safety protocols, trained personnel, and marine access planning ensured efficient and safe execution
Final Outcome
The project successfully delivered a durable, high-performance marine coating system that enhances both the aesthetic consistency and structural protection of the downstand elements. The finished surfaces provide long-term resistance to coastal environmental conditions while maintaining alignment with the project’s architectural vision.
