Abstract
A premixed photoluminescent composition and related hardened form and method of forming joints for pavers or stones. The premixed photoluminescent composition comprises solid aggregates; a photoluminescent particulate component adapted to emit light when photoexcited; and a binder. When in contact with an activator, oxygen or water, the binder is adapted to harden into a water-resistant binder matrix that bonds the solid aggregates and embeds the photoluminescent particulate component. In use, the water-resistant binder matrix has a transparency allowing transmission of at least a portion of the light emitted by the photoluminescent particulate component.

A method of making a hardened water-resistant photoluminescent composition, the method comprising:
- providing a dry premixed photoluminescent composition to form a composition layer, the premixed photoluminescent composition comprising solid aggregates, a photoluminescent particulate component adapted to emit light when photoexcited, and a water-activated binder;
- and
- distributing water onto the composition layer to activate conversion of the water-activated binder, via diffusion of water, into a water-resistant binder matrix having a transparency allowing transmission of at least a portion of the light emitted by the photoluminescent particulate component, thereby forming the hardened water-resistant photoluminescent composition.
