I applied epoxy coating to a residential sewer line today using specialized equipment. After thoroughly cleaning and drying the pipe with high-pressure water jetting and specialized drying equipment, I conducted a precise measurement of the pipe to ensure proper epoxy mixture ratios. The epoxy coating process involved carefully controlling the application speed and pressure to achieve uniform thickness throughout the pipe. I paid special attention to joint areas and previous repair spots, applying additional material where needed. Following application, I used UV curing equipment to ensure proper hardening and conducted a post-installation camera inspection to verify complete coverage.
