MoistureProblemsinConcreteGarageFloors
Florida's high water table and humidity make moisture one of the biggest threats to garage floor coatings. Testing before installation is not optional — it is essential.
What you need to know
- Moisture vapor transmission (MVT) can push coatings off the concrete from below, causing bubbling and delamination.
- Florida homes are especially susceptible due to high water tables and year-round humidity.
- Calcium chloride testing and relative humidity testing are the standard methods for measuring slab moisture.
- If moisture levels are too high, a vapor barrier or moisture mitigation system must be applied before coating.
- Skipping moisture testing to save time or money is the most expensive shortcut in garage floor coating.
If you're dealing with this issue, the fix usually starts with a proper slab assessment. We can take a look and give you honest options — no obligation.
