GlowZone has developed the first 2-component photoluminescent system to allow users to easily add PL material on concrete stairs, around a swimming pool or spa, or to any paintable surface where photoluminescence could add safety or convenience. The system keeps the two components separate until they are mixed together in the nozzle with the perfect mix ratio for maximum ease of application. Years of R&D have gone into perfecting this system to ensure that a single coat will pass brightness ratings for building codes.
