1. Assess Substrate Condition Before Starting Work
Before launching into any surface preparation project infrastructure professionals must perform a comprehensive substrate assessment to guarantee optimal results and long term durability. Understanding the current condition of your surface is the foundational step that determines the success of your entire surface treatment strategy.
Substrate assessment involves a systematic evaluation of multiple critical factors that impact surface quality and treatment effectiveness. This process goes far beyond a simple visual inspection and requires a nuanced understanding of material characteristics.
Key components of substrate condition assessment include:
- Identifying surface contaminants
- Measuring surface roughness and profile
- Detecting existing corrosion or degradation
