Moisture vapor barriers prevent epoxy floor failure by forming a seamless, non-porous membrane that blocks water vapor from rising through the naturally porous concrete slab. Because concrete acts like a wick, drawing moisture from the ground, untreated slabs allow vapor to migrate upward and condense directly beneath the epoxy film. Without a barrier, this trapped moisture creates pressure that causes the coating to blister, peel, and delaminate.
We utilize low-VOC, 100% solid epoxy systems engineered specifically to:
- Stop vapor transmission: By sealing the surface, the barrier prevents moisture from reaching the underside of the epoxy and breaking the adhesive bond.
- Resist hydrostatic pressure: These systems are designed to withstand the physical force of water pushing up from below the slab.
- Prevent environmental damage: The dense barrier helps inhibit the growth of mold and protects against freeze-thaw damage, which is particularly common in Alberta’s climate.
To ensure these barriers perform effectively, we always start with Diamond Grinding to open the concrete’s pores for a strong mechanical bond, followed by ASTM F2170 or F1869 testing to confirm moisture levels are within an acceptable range. This comprehensive approach ensures the flawless finishes your business deserves while protecting your long-term investment.

Why is Moisture Testing Important before Applying Epoxy?
Read More »Moisture testing is a critical first step because concrete is naturally porous, acting like a wick that draws moisture up from the ground. If this moisture is trapped under an impermeable coating without being properly addressed, it creates pressure that can cause the epoxy to blister, peel, and delaminate, leading to a total floor failure.

Why is a Uv Stable Topcoat Necessary for Outdoor Epoxy Projects?
Read More »A UV-stable topcoat is essential for outdoor epoxy projects because standard epoxy coatings are inherently vulnerable to ultraviolet (UV) degradation. When exposed to direct sunlight over extended periods, traditional epoxy undergoes a photochemical reaction that causes visible damage, including chalking (the development of a powdery residue on the surface) and yellowing or amber discoloration. To […]

How does Polyaspartic Compare to Epoxy for Sun Exposure?
Read More »Polyaspartic coatings are significantly more UV-stable than standard epoxy. While standard epoxy is prone to rapid UV degradation when exposed to the intense sun found in Alberta, polyaspartic formulations use aliphatic chemistry that resists yellowing and chalking at the molecular level. When comparing the two for sun exposure, we have found that polyaspartic topcoats offer […]
