Concrete Moisture and Epoxy Coatings
Water vapor moving up through a slab is a leading cause of coating failure. Testing before install prevents surprises.
Warning Signs
Dark spots, efflorescence, past coating delamination, and basement slabs with no vapor barrier.
Testing
ASTM-style relative humidity probes and calcium chloride tests quantify vapor movement.
Mitigation
Moisture-tolerant primers create a barrier so the coating stack can perform as designed.
Frequently Asked Questions
How is moisture measured?
Calcium chloride tests, relative humidity probes and plastic sheet tests. Different systems have different tolerance thresholds.
Can moisture be mitigated?
Yes, with a moisture-mitigation primer or vapor-barrier resin before the main coating stack.
