Kauai is the wettest of the main islands — Mount Waialeale averages over 450 inches of annual rainfall — and yet the south and west sides are dry and intensely sunny. A coating system for Kauai often has to solve water intrusion, solar heat, and salt corrosion simultaneously.
Heavy rain, lush growth, humidity, and short-term-rental tourism economy. Roof leaks and mold are the dominant problems.
Mixed climate — moderate rain and moderate sun. Most commercial buildings on the island sit here.
Dry, sunny, salt-aerosol heavy. The resort and hotel infrastructure carries continuous cooling load all year.
The driest part of Kauai. Agricultural land, coffee farms, military installations (Pacific Missile Range Facility). Solar heat is intense.
Coatings ship by pail to Kauai with a few days’ lead time. Site visits scheduled in advance for commercial projects; residential typically handled with detailed photos and a phone consultation followed by an applicator visit.
