RUSTGRIP ® primer and SUPERTHERM ® top coat

Versa Cold Storage Facility - SUPERTHERM

These infrared scans taken prior to the application of a primer coat of RUSTGRIP ® and a combined base coat and top coat of SUPERTHERM ® show black spots where the insulation has totally failed due to moisture. There is so much moisture in the insulation that it actually has a NEGATIVE R value and is now conducting heat instead of resisting heat ( Water is a better conductor than resistor ). This increased the problems inherent in all metal substrates being conduction, condensation and corrosion.

This caused the existing paint to crack and peel. It would have been extremely beneficial to have been given these scans prior to commencing this project. Unfortunately they were not revealed until after the project was completed.

Because of the extreme condensation on this substrate, a base coat of EPOXOTHERM ® should have been applied over the RUSTGRIP ® and then top coated with SUPERTHERM ®. These scans also would have identified areas were a higher build of the EPOXOTHERM ® / SUPERTHERM ® system was required.

Note the TEMPERATURE SCALES on the side of each of the scans located below. The temperature range of the scan taken BEFORE the coating system was applied is from 18.2°C - 25.1°C ( 64.76°F - 77.18°F ). The temperature range of the scan taken AFTER the coating system was applied is from 20.9°C - 35.6°C ( 69.62°F - 96.08°F ). The adjustment was required because of the much higher ambient temperature on the day the AFTER coating scan was taken.

Note: Also at the same time that we were doing the worst wall ( East wall ) a coat of elastomeric was applied by another company to one test panel on a far less challenging area of the South wall. Now less than two years later it is already delaminating, cracking and peeling. The SUPERTHERM ® is still fully bonded and looks like new in addition to providing ongoing Thermal protection.
