How long is the life of epoxy colored sand floor coating?

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.
