How do I know if my slab needs a moisture vapor barrier?

You need a professional moisture vapor emission test. We perform this on every job before recommending a system. The test measures how much moisture vapor is passing through your slab. If readings are elevated, we recommend a barrier before coating.

What happens if I skip the moisture vapor barrier?

The coating may delaminate — moisture vapor pressure builds up under the coating and can push it off the slab. You'll see bubbling first, then peeling. This is a preventable failure with proper testing and treatment.

Which properties in Central Florida are worth testing carefully?

Older slabs, lakefront and low-lying properties, and any home where a previous coating has failed are worth testing carefully. We test every slab regardless of age or location — the test result, not assumptions, guides our recommendation.

Does a moisture vapor barrier add to the cost?

Yes — a moisture vapor barrier system adds material and labor cost to the project. It's far less expensive than having a coating fail and paying for removal and reinstallation. We'll include it in your written quote if testing indicates it's needed.

Does the moisture vapor barrier affect the finished appearance?

No. The barrier is installed as a base coat and is completely covered by the decorative system on top. The finished floor looks identical whether or not a barrier was required.

Do I Need a Moisture Vapor Barrier in Florida?

Florida's water table is high, the humidity is relentless, and many slabs were poured before vapor barriers were standard practice. The result: some Central Florida garage floors have elevated moisture vapor that can affect any coating applied without proper treatment.
