A protective coatings project being “simple and straightforward” is a false and dangerous misconception. One “minor” pitfall can lead to subpar results, wasting resources and compromising the integrity of assets. Moreover, if a coatings project involves chemical storage tanks, potable water systems, and other structures designed to hold hazardous substances or liquids for human consumption, the project immediately takes on added layers of complexity. A single mishap could cause environmental contamination and health hazards.
To ensure an error-free and fail-proof outcome, below, we have broken down the most common coating mistakes and how to avoid them.
1. Poor Surface Preparation
A leading cause of coating failure is inadequate surface preparation. Skipping or speeding through this crucial step can result in poor adhesion, blistering, wrinkling, peeling, and uneven coverage.
Proper surface preparation is a multi-step process involving (but not limited to):
- Surface condition assessments
- Thorough cleaning via abrasive blasting techniques
- Removal of previous coatings, grease, chlorides, and other surface contaminants
- Removal of any loose and rusted parts on the surface
- Surface profiling
- Surface drying to draw out any remaining moisture before applying a fresh coating
These surface preparation steps support optimal adhesion, setting the foundation for a successful coatings project.
2. Using Low-Quality Materials
While using poor-quality coatings and materials might save you money upfront, it is a recipe for disaster in the long haul. Inferior coatings offer mediocre protection and can deteriorate quickly. In consequence, your assets will require constant reapplications, costing you more money and time.
Instead, invest in high-quality coatings designed for the intended surface and environmental conditions. Quality materials provide better protection, longer lifespan, and improved performance.
3. Failure to Follow Product Instructions
Some products have a specific sweat-in time, which refers to the waiting period between mixing and applying a two-part product, such as an epoxy. Coatings also require thorough mixing using mechanical mixers or stirring tools for a consistent blend.
Neglecting the manufacturer’s instructions or treating protective coatings like regular paint can result in uneven, underperforming coatings that do not offer sufficient corrosion resistance.
4. Overlooking Environmental Factors
Environmental conditions play an essential role in a coating project’s success or failure. Factors such as ambient and surface temperature, humidity, dew point temperature, and air circulation can influence curing.
Working with protective coatings specialists who can (1) monitor environmental conditions, (2) understand the impact of sudden changes in temperature, and (3) follow product specifications for recommended application conditions is crucial to achieving satisfactory results.
5. Not Hiring an Independent Coating Inspector
The absence of a coatings inspector poses severe risks to your project. Without their impartial expertise in all of the above, you risk inadequate coatings, which can lead to premature corrosion, costly rework, and safety hazards.
Hiring an independent coatings inspector from Industrial Inspection Group guarantees quality work, industry compliance, and long-term asset reliability. Our professionals understand NACE-SSPC processes and procedures at an expert level, ensuring the safety and protection of your investments.
