Epoxy flooring makes way for a solid surface and finds use in the toughest industrial environments. It consists of epoxy at its core, which in turn includes resins and hardeners as its two key components. The surface of the floor therefore comprises numerous layers of epoxy down to a depth of around two millimetres, which makes it rigid and resistant to degradation. However, a major impediment to the longevity of these rugged surfaces comes from moisture vapor transition (MVT), which is responsible for much of the bond failure and adhesion-related issues.

Common Moisture Problems
Moisture vapor rises by osmosis and condenses on the surface of the slab, only to damage the epoxy flooring via bubbling, blistering, delamination, efflorescence, softening, mold, dissolution and more other undesirable situations.
In particular, adhesive degradation is the primary moisture problem in epoxy flooring. It occurs when moisture emerges through the concrete and fills the space between the flooring and the concrete. As the humidity continues to rise, the adhesive breaks down. It also tends to cause the flooring to pop and blister, which is another common problem resulting from excess moisture.
If the moisture remains between the floor finish and the concrete for a long time, it could pave the way for mold growth and therefore affect the air quality issues of the structure. Efflorescence is another major obstacle to epoxy flooring that results from the soluble salts present in the material. In addition to this, defects such as stains, ejections, warping of tiles and condensation are other important reasons that promote moisture and destroy the flooring.
Fights moisture damage
Some important measures such as proper flooring choice or proper flooring for moisture vapor control could be effective in preventing moisture from wreaking havoc. Additionally, several test procedures to detect the source of moisture are equally effective in knowing if the surface is ripe for epoxy flooring.
For example, concrete moisture testing is a notable process prior to flooring installation. It is useful for determining the moisture situation of a slab and detecting any problems occurring in the ground. Similarly, the calcium chloride test is another beneficial method to determine the moisture content in a concrete slab.
Similarly, the baseline test is another useful procedure for testing concrete floors and slabs. It involves drilling a part of the slab to test it in the laboratory by professionals, and gives a complete analysis of each part that forms the slab. It detects contaminants in the slab, which can interfere with the installation of the floor covering.
