Q-Lab Florida exposure site is located south of Miami on the southern tip of Florida, in the only true subtropical region in the continental United States.

This site has high-intensity sunlight, high annual UV, high year round temperatures, abundant rainfall and very high humidity. When combined, these factors create the harsh climate that makes Miami the ideal location for testing exterior durability.

The moist, humid climate has been proven especially useful for certain types of testing:

• Moisture sensitivity of products like coatings, building materials, and some plastics
• Mildew resistance
• Corrosion testing
  

Moisture sensitive products like coatings and building materials, and some plastics are particularly affected. Florida is also an excellent site for testing mildew resistance.

Natural exposure testing is an essential part of any weathering and light stability test program. Material scientists often use "Florida Weathering" or "Arizona Weathering" as international benchmarks for material weatherability testing,  For a complete outdoor testing program, many companies test their products in both Florida and Arizona.
