A method for providing a self-illuminating ground surface 10, comprises the steps of spraying a liquid binding agent 16 from a first dispensing device onto a ground surface 100 to be coated; spraying particulate media 18 under pressure from a second dispensing device onto the ground surface 100, whereby the binding agent 16 adheres the particulate media 18 to the surface 100 to form a base layer 12; and applying a liquid sealant 14 over the base layer 12; wherein the particulate media 18 comprises a mixture of a first particulate 26 and a second particulate 24 and the first particulate 26 comprises a photoluminescent material. The sealant 14 is flexible and water impermeable. The sealant 14 is preferably derived from an aliphatic polyaspartic and hardener. The preferred photo-luminescent material 26 comprises a rare earth strontium aluminate. The second particulates 24 are preferably construction aggregate, especially stone or glass chips. The method can be used for illuminating roads, cycle lanes or footpaths.
