Buying Guide: Key Purchase Considerations
- Surface type and exposure: Choose coatings rated for exterior use on horizontal concrete. Avoid vertical surfaces or areas with hydrostatic pressure unless specified by the manufacturer.
- Finish and appearance: If you want a decorative look, consider epoxy with marble-like colored sand or high-gloss options. For a more practical look, satin finishes balance dirt visibility and maintenance.
- Durability factors: Look for resistance to hot tire pickup, wear, chemical exposure, and moisture. Two-part systems generally offer stronger adhesion and longer life than one-part formulas.
- Application conditions: Check temperature and humidity guidelines. Self-leveling products help reduce ridges but may require precise substrate prep for exterior conditions.
- Coverage and project size: Larger spaces require more material; volume per coat varies by product. Plan for extra material to account for porosity and surface roughness.
- Maintenance and safety: Consider anti-slip features or aggregate textures for wet outdoor areas. Ensure proper ventilation during application and curing outdoors.
