The #1 hidden cause of epoxy failure in Central Florida isn’t the coating — it’s water vapor pushing up through the slab. Here’s what every homeowner should know before coating any concrete here.
Florida slabs are different
Much of Central Florida sits on a high water table, and many homes — especially in lower-elevation areas of West Orange and Osceola counties — have slabs poured with minimal or degraded under-slab vapor barriers. Moisture constantly migrates upward through the concrete’s capillaries. You can’t see it, but a coating can feel it.
What happens if you coat over it
Vapor pressure builds under the coating film and pushes: first bubbles, then delamination — often within the first rainy season. This is why “the last company’s epoxy peeled” is the most common call we get.
How we prevent it
- We moisture-test every slab before quoting a system — calcium chloride or meter testing, documented.
- Moisture-barrier epoxy primers are formulated to tolerate high vapor drive and lock the surface.
- Breathable systems for extreme cases, like lakefront properties and boathouses.
This testing is included in every free estimate — it’s a standard step in our process, not an upsell. If a contractor quotes your floor without mentioning moisture, that’s a red flag. Schedule your free slab assessment.
