What is Moisture Vapor Transmission (MVT)?

Not all industrial flooring companies in Dallas are created equal.


Some will do the job right, protecting your investment for years to come. Others might cut costs – but they might also be cutting corners.


One reason it’s important to find a reputable industrial flooring company in Dallas is because moisture vapor transmission is a very real thing – and it can wreck havoc on your brand new epoxy floors.


What is Moisture Vapor Transmission?

Moisture Vapor Transmission (MVT) occurs when water vapor comes up through a concrete slab, producing a high-PH liquid at the surface. This water vapor then breaks down flooring coating systems.


Determining Moisture Vapor Transmission

Professionals can administer several tests to determine the moisture levels in your slab before installing an epoxy floor coating. The Calcium Chloride Test, Plastic Sheet Test, and Relative Humidity (RH) tests are the most common, with the Calcium Chloride Test being the most popular. It is critical that you choose a seasoned professional to administer these tests to ensure that levels are where they should be. Before installing an epoxy floor, moisture levels in the concrete must be below 75%, even better if they are lower in the humidity of Texas!


Effects of Moisture Vapor Transmission

The number #1 problem associated with MVT is cracking and peeling of epoxy floor coating systems. You might also notice the coating bubbling up or even emitting an oily substance on your Dallas epoxy floors. This is especially true in Texas where heat and moisture levels are high most of the year.
