What to Look for When Hiring a Coating Contractor: Spotlight on QP1 and QP3

Choosing the right contractor for your industrial coating project is one of the most critical decisions you’ll make. The stakes are high—coatings are essential for protecting assets from corrosion, wear, and environmental stressors. Poor workmanship can lead to premature failures, increased maintenance costs, and even safety risks.

One of the best ways to ensure your project is in good hands is to look for contractors with QP1 and QP3 certifications. These certifications, issued by the  Association for Materials Protection and Performance (AMPP), are the industry’s gold standard for quality, safety, and compliance.

This checklist will help you vet potential contractors and ensure they meet the highest standards for your project.

1. Certification Credentials

Checklist:

• Is the contractor QP1-certified for field applications?
• Is the contractor QP3-certified for shop-applied coatings?
• Can they provide documentation of their certifications?

Why It Matters:
QP1 and QP3 certifications prove the contractor has been vetted for technical expertise, quality control, and adherence to safety and environmental regulations. Without these certifications, there’s no guarantee they can meet industry standards.

2. Experience and Track Record

Checklist:

• How many years of experience does the contractor have in industrial coatings?
• Do they have experience with projects similar to yours (e.g., bridges, pipelines, tanks, or structural steel)?
• Can they provide references or case studies?

Why It Matters:
Experience is a strong indicator of a contractor’s ability to handle complex projects and deliver consistent results. A QP-certified contractor will also have a proven history of successful projects.

3. Surface Preparation Expertise

Checklist:

• Does the contractor follow AMPP standards for surface preparation (e.g., SSPC-SP10 for near-white metal blast)?
• What surface preparation methods do they use (e.g., abrasive blasting, power tool cleaning)?
• Can they verify surface cleanliness and profile with industry-standard testing?

Why It Matters:
Surface preparation is critical for coating adhesion and performance. A contractor with QP1 certification will have the tools, techniques, and knowledge to ensure the substrate is properly prepared.

4. Coating Application Standards

Checklist:

• Does the contractor use advanced equipment, such as spray systems, to ensure uniform coating application?
• Do they monitor environmental conditions (e.g., temperature, humidity) during application?
• Can they meet manufacturer specifications for film thickness and curing times?

Why It Matters:
Proper application techniques are essential for creating a durable, long-lasting coating system. QP-certified contractors follow strict guidelines to ensure coatings are applied correctly the first time.

5. Quality Control Measures

Checklist:

• Does the contractor conduct quality control testing, such as:
• Dry film thickness measurements?
• Adhesion tests?
• Surface cleanliness checks?
• Do they maintain detailed documentation of inspections and test results?
• Can they provide a clear quality assurance plan?

Why It Matters:
Quality control ensures that coatings meet project specifications and perform as intended. QP1 and QP3 certifications require contractors to implement rigorous quality assurance processes.

6. Safety and Environmental Compliance

Checklist:

• Does the contractor have OSHA-compliant safety protocols?
• Do they use containment systems to manage hazardous materials?
• Are they compliant with environmental regulations for waste management and emissions?

Why It Matters:
Safety and environmental compliance are critical for protecting workers, the public, and the surrounding environment. QP-certified contractors are regularly audited to ensure compliance with these standards.

7. Skilled Workforce

Checklist:

• Are the contractor’s employees trained and certified in industrial coating techniques?
• Do they participate in ongoing education to stay current with industry advancements?
• Can they provide evidence of workforce qualifications?

Why It Matters:
A skilled workforce is essential for delivering high-quality results. QP certifications require contractors to maintain a team of trained professionals.

8. Facility Capabilities (for Shop-Applied Coatings)

Checklist:

• Does the contractor have a dedicated, climate-controlled shop for coatings?
• Can they demonstrate proper handling and storage of materials?
• Do they have automated equipment for consistent, precise application?

Why It Matters:
QP3-certified contractors operate in controlled environments, which ensures coatings are applied under optimal conditions. This is especially important for components that require a high degree of precision.

9. Communication and Transparency

Checklist:

• Does the contractor provide detailed project proposals with clear timelines and cost estimates?
• Are they transparent about their processes, certifications, and past projects?
• Can they offer regular progress updates and reports during the project?

Why It Matters:
Open communication builds trust and ensures that everyone is on the same page throughout the project. QP-certified contractors are accustomed to maintaining detailed documentation and sharing it with clients.

10. Reputation and Reviews

Checklist:

• Do they have positive reviews from previous clients?
• Are they known for meeting deadlines and staying within budget?
• Have they earned industry awards or recognition?

Why It Matters:
A contractor’s reputation is a reflection of their reliability and commitment to excellence. Choosing a QP-certified contractor with strong client endorsements ensures peace of mind.
