The lifespan of epoxy colored sand floor coatings is affected by factors such as material quality, construction process, and operating environment. A comprehensive analysis is provided below:
1. Lifespan Range
High-quality epoxy colored sand flooring: 10-15 years (indoor, dry environment)
High-performance epoxy self-leveling colored sand: 15-20 years (thickness ≥ 2mm)
Low-quality products: Lifespan may be shortened to 5-8 years (low resin content or improper construction)
Specific application differences
Humid areas (such as kitchens and bathrooms): 8-12 years (regular maintenance required)
Outdoor environments: 5-8 years (weather-resistant product required)
Heavy-duty industrial areas: 6-10 years (high-hardness formula required)
2. Key Influencing Factors
Material Quality
High-purity epoxy resin + weather-resistant pigments can extend the lifespan to 15 years
High-quality domestic materials offer high cost-effectiveness and a stable lifespan.
Construction Technology
Improper base preparation (moisture content >8%) can lead to hollowing and shedding within 1-2 years.
Proper construction (meeting required thickness and dense filling) can increase lifespan by 30%.
Maintenance
Regular cleaning (avoiding strong acids and alkalis) can reduce surface corrosion.
Promptly repairing local cracks can prevent the problem from spreading.
3. Recommendations for Extending Lifespan
Material Selection
Preferably use solvent-free, environmentally friendly formulas (low VOC, anti-aging).
Recommended thickness ≥ 3mm for heavily loaded areas.
Construction Controls
Ensure base strength ≥ C25 and moisture content ≤ 8%.
Expansion joints require elastic filler (displacement ≥ 5mm).
Usage and Maintenance
Avoid scratches with sharp objects; heavy equipment should be equipped with cushioning pads.
