Hot Project, Freezing Temperatures
TMI Coating recently completed installation of a secondary containment lining for an expanding medical company. The customer needed the outdoor containment dike ready for service ASAP, requiring the work be completed in January during sub-zero temperatures.
- The FIBERLIFE lining, consisting of layers of fiberglass reinforcing mat saturated in a chemical resistant vinyl ester resin, was installed inside a concrete dike located outdoors.
- Erected a temporary enclosure and heated the area to allow for lining installation and proper material cure.
– Indirect heat used to safely heat the area and apply coating.
– Zero degree overnights and 55 minimum temperature requirements for proper cure challenged heating options.
– Needed to heat around the clock. 24 hour heat required overnight supervision and fueling.
- Mechanically abrade all surfaces per material specifications.
- Applied lining suitable for hydrogen peroxide spills.
– System included prime, 2 full coats of fiberglass mat, and an aggregate broadcast to the floor for slip resistance prior to a final seal coat with wax for added chemical resistance.
– New poured walls have bugholes which need to be filled with epoxy mortar prior to applying system.
- Work long hours, including overnights and weekends, to minimize disruption and return the dike to the owner for use.
- Fiberglass mat had to have rough areas sanded between coats to eliminate rough areas and voids in chemical resistant lining.
- Prior to final coat a flood (seal) coat was added to ensure a pinhole free finish.
- A final wax coat was added to all surfaces for added chemical resistance.
- The floor was broadcast with aggregate on the final coat for slip resistance when the containment dike is put into service.
All work was completed safely, on time, and within budget.
