At Elegant Coatings, we understand that epoxy flooring moisture represents the silent destroyer of the installation process, capable of compromising even the most meticulously planned installations.
Research indicates that moisture-related failures account for approximately 75% of all epoxy flooring performance issues1, making moisture management a critical consideration for both contractors and homeowners.
Understanding Moisture’s Impact
Concrete is inherently porous, acting like a massive sponge that can retain significant moisture levels. In Vancouver’s unique climate, concrete’s inherent porosity becomes an even more critical challenge for flooring systems. Research from the National Research Council of Canada highlights that concrete acts like a massive moisture-retaining sponge, with pore structures significantly impacting material performance.
Local studies reveal that:
- Moisture levels above 6% can compromise structural integrity
- Concrete’s pore characteristics directly influence water retention capabilities
- Vancouver’s high-humidity environment can accelerate moisture-related degradation
The National Research Council’s investigations demonstrate that concrete’s pore structure is not uniform, with interlayer spaces capable of retaining substantial moisture. In the Vancouver region, where humidity levels fluctuate dramatically, these moisture retention properties can pose significant risks to epoxy flooring installations.
Specific findings from Canadian research indicate that:
- Pore sizes ranging from 8 micrometers can dramatically affect material durability
- Water absorption can vary significantly based on concrete mix composition
- Supplementary cementitious materials can influence moisture penetration rates
These insights underscore the critical importance of comprehensive moisture management strategies, particularly in moisture-prone environments like Vancouver’s coastal climate.
Advanced Epoxy Flooring Moisture Testing Techniques
Calcium Chloride Test
This method quantifies moisture vapor emission rates using a standardized scientific approach. By placing a pre-weighed calcium chloride container on the concrete surface for 60-72 hours, professionals can:
- Measure moisture vapor emission in pounds per 1,000 sq. ft.
- Determine surface-level moisture characteristics
- Follow ASTM F1869 standardized testing protocols
Relative Humidity Probe Testing
Unlike surface-level assessments, this technique provides comprehensive internal moisture analysis. By inserting specialized sensors directly into the concrete, professionals can:
- Measure core concrete humidity levels
- Obtain precise relative humidity readings
- Utilize ASTM F2170 testing standards
- Evaluate long-term moisture potential within the concrete structure
Key Differences:
- Calcium Chloride Test: Surface-level moisture measurement
- Relative Humidity Probe: Internal moisture comprehensive analysis
Both methods are complementary, offering a holistic understanding of concrete moisture conditions critical for successful epoxy flooring installations.

The Foundation of Epoxy Flooring Moisture Resistance
Successful moisture management begins with meticulous surface preparation. Diamond grinding represents a sophisticated approach to concrete surface optimization. This technique uses industrial-grade diamond tools to mechanically remove surface contaminants, creating a perfectly profiled substrate ready for epoxy flooring moisture barrier application.
Shot blasting takes surface preparation to another level. Specialized equipment propels steel shot at high velocities, effectively removing surface layers and creating a micro-textured profile. This process not only cleans the concrete but also creates microscopic peaks and valleys that dramatically improve moisture barrier adhesion.
High-pressure water jet profiling offers a complementary approach to surface preparation. Powerful water streams remove surface contamination while simultaneously creating an ideal surface texture. This method provides exceptional cleaning without introducing additional mechanical stress to the concrete substrate.
Environmental Control
Controlling the installation environment is as critical as surface preparation. Temperature management plays a crucial role in moisture mitigation. Maintaining a consistent temperature between 60-80°F ensures optimal chemical reactions during moisture barrier and epoxy application.
Humidity control represents another critical factor in successful epoxy flooring moisture management. Professional-grade dehumidifiers create a controlled environment that minimizes ambient moisture interference. By reducing atmospheric humidity, installers can prevent moisture entrapment and ensure superior coating performance.
Our approach at Elegant Coatings integrates these advanced techniques, transforming moisture management from a challenge into a precise, engineered solution.
