However, a high-performance, long-lasting epoxy floor is not achieved by chance. Its success depends on strict control over every stage, from the substrate to the topcoat. Based on our extensive industry experience, we have outlined eight critical factors to ensure the success of your epoxy flooring project, serving as a reference and guideline for your construction teams.
The substrate is the foundation of the flooring system. An inadequate substrate is a primary cause of later issues such as delamination, peeling, and blistering. An ideal concrete substrate should meet the following criteria:
Adequate Strength: Concrete strength should be no less than C25 to ensure it can withstand design loads.
Smooth and Dense Surface: A power trowel is recommended for finishing, with a flatness tolerance of no more than 2mm under a 2-meter straightedge.
Proper Drying: Newly poured concrete requires sufficient curing (typically recommended for 28 days or more), with a moisture content below 4%. Effective moisture barriers are essential for ground-level slabs.
Proper Treatment: Control joints should be pre-planned and appropriately addressed. All repairs must be made with high-strength materials (such as epoxy mortar or high-strength polymer mortar) to ensure compatibility with the original substrate.
Our Recommendation: Conduct a comprehensive substrate inspection and evaluation before construction begins. Any substandard surfaces must be strengthened, repaired, or moisture-treated—this is the first step toward a successful project.
Surface preparation is far more than simple cleaning. Its core purpose is to remove laitance and contaminants, achieving a uniform, sound, clean, and properly profiled surface to ensure optimal adhesion.
Mechanical Grinding: Use professional grinding equipment to remove laitance and weak layers, opening the surface pores.
Complete Cleaning: Remove all dust with industrial-grade vacuum cleaners. For oil stains, use specialized degreasers for chemical cleaning and rinsing.
Detail Work: Pay special attention to edges and corners using hand tools. Cracks and holes should be pre-filled with appropriate materials (such as epoxy crack filler).
There is no one-size-fits-all solution. The coating system must be perfectly tailored to the floor's end use.
Assess Requirements: Clearly define the mechanical stresses (e.g., traffic type, impact), chemical exposure (e.g., oils, cleaners), cleanliness requirements, and aesthetic expectations.
Select the System: Choose the most suitable system—whether thin-film, mortar, or self-leveling—based on the floor's needs. For example, heavy-duty warehouse areas may require a multi-layer epoxy mortar system, while electronics cleanrooms benefit most from high-leveling self-leveling topcoats.
Environmental conditions directly affect material reaction and final film formation.
Temperature and Humidity: Ambient and substrate temperatures are generally recommended to be above 10°C, with relative humidity below 85%. Ensure the substrate temperature is at least 3°C above the dew point to prevent condensation.
Airflow and Cleanliness: Maintain good ventilation in the work area but avoid strong drafts that could cause surface defects. The application environment should be as dust-free as possible to prevent contamination of uncured coatings.
Even with high-quality materials, improper handling can lead to failure.
Precise Proportioning: Strictly follow the mix ratio specified in the product technical data sheet, using a scale to accurately measure Part A (resin) and Part B (hardener).
Thorough Mixing: Use a mechanical mixer to blend the two components completely and uniformly, adhering to the specified pot life.
Proper Application: Use appropriate trowels or squeegees to ensure uniform film thickness. Complete application within the material's pot life to avoid lap marks.
As the "heart" of the epoxy system, the selection of hardener is critical—it directly determines the floor's final performance.
Performance Matching: Choose a hardener fully compatible with the resin, application environment, and performance requirements (e.g., hardness, flexibility, chemical resistance).
Addressing Challenges: In harsh conditions such as low temperatures or high humidity, specially formulated hardeners (e.g., low-temperature cure, moisture-tolerant) must be used to ensure proper reaction and curing.
Aesthetic Considerations: For topcoats requiring high decorative appeal and UV resistance, select high-quality modified amine or cycloaliphatic amine hardeners.
Post-application curing is crucial for the development of the coating's properties.
Adequate Curing Time: Do not allow traffic or exposure to chemicals until the specified cure time has been reached .
Controlled Environment: Maintain stable temperature and humidity during curing. Use barriers and warning signs as necessary.
A successful project is the result of combining high-quality products with professional expertise.
Select a Trusted Supplier: Partner with suppliers who provide high-quality, consistent epoxy resins and compatible hardeners, backed by professional technical support.
Rely on Experienced Contractors: A skilled application team can accurately assess site conditions, strictly follow procedures, and effectively handle unforeseen issues.
By diligently following these eight essential keys, you will significantly increase the success rate of your epoxy flooring projects, creating aesthetically pleasing, durable, and high-performance floors.
