Epoxy Coating & Lining
High-performance protective coatings for cooling tower basins, chiller tube sheets, and mechanical substrates.
Corrosion Control
Corrosion is the enemy of mechanical longevity. Our coating systems arrest rust and create a monolithic barrier against leaks.
Basin Leaks
Pitting and seam failure in cooling towers lead to water loss.
Tube Sheet Decay
Galvanic corrosion between tubes and sheets causes bypass.
Structural Rust
Oxidation compromises the integrity of support frames.
Life Extension
Adding 10-15 years to the life of a metal asset.
Surface Preparation & Application
Success is 90% preparation. We adhere to strict SSPC surface prep standards.

Measurable Performance Recovery
Re-lining a cooling tower basin costs approximately 15-20% of the price of a new tower, with similar longevity benefits.
Frequently Asked Questions
How long does commercial epoxy coating take to cure before equipment can return to service?
Most 100% solids epoxy systems achieve immersion-ready cure in 24–48 hours at ambient temperature. BAM verifies cure hardness before authorizing system refill to prevent premature coating failure. Total project duration including surface preparation, application, and cure typically spans 3–5 days per asset.
Can new epoxy be applied over an existing failing coating?
Generally, no. BAM removes old, failing coatings down to bare substrate using abrasive blasting to SSPC SP-6 or SP-10 standards. Coating over delaminated material traps moisture and corrosion underneath, guaranteeing premature failure. Proper surface profiling is 90% of a successful lining system's longevity.
What surfaces can be epoxy coated in commercial HVAC equipment?
BAM applies protective coatings to cooling tower basins, chiller tube sheets and water boxes, condensate drain pans, structural steel supports, and mechanical room floors. Each substrate requires a specific epoxy chemistry—ceramic-filled for abrasion resistance, flexible urethane for thermal cycling, or hybrid systems for chemical immersion environments.
How does epoxy basin lining compare in cost to cooling tower replacement?
Relining a corroded cooling tower basin typically costs 15–20% of a full tower replacement and adds 10–15 years of service life. It also eliminates the crane mobilization, structural engineering review, and extended downtime a replacement demands. BAM's coating systems achieve zero-leakage performance verified by holiday testing.
What surface preparation standards does BAM follow for epoxy application?
BAM adheres to SSPC (Society for Protective Coatings) surface preparation standards. Depending on the substrate condition, we blast to near-white metal (SP-10) or commercial blast (SP-6), verify anchor profile depth with replica tape, and perform chloride testing to ensure no salt contamination compromises adhesion. Shortcuts in prep guarantee coating failure.
How is the quality of an epoxy coating verified after application?
BAM performs three post-application tests: dry film thickness measurement to confirm specified mil build, holiday (spark) testing to detect pinholes or discontinuities, and adhesion pull-off testing to verify bond strength to the substrate. A complete inspection report with test data is included in every project closeout package.
