  • GB 1300929.5 describes a method in which a photo- luminescent pigment is mixed with a liquid sealant and sprayed over a base layer consisting of a binding agent and a particulate medium such a stone chips. In this way a ground surface can be created which absorbs UV radiation by day and re-emits radiation after dark to produce a gently glowing surface .
  • the present invention provides an alternative method which produces an improved end result.
  • a method for providing a self-illuminating ground surface comprising the steps of: spraying a liquid binding agent from a first dispensing device onto a ground surface to be coated; spraying particulate media under pressure from a second dispensing device onto the ground surface to be coated, whereby the binding agent adheres the particulate media to the, surface to form a base layer; and applying a liquid sealant over the base layer; wherein the particulate media comprises a mixture of a first particulate and a second particulate and the first particulate comprises a photoluminescent material ,
  • the photoluminescent particulate absorbs UV radiation during the daytime and re-emits that radiation after dark to provide a gentle illumination, thus showing users where they are going and revealing obstacles in their path, without any significant contribution to light pollution.
  • the illumination provided requires no ongoing energy costs, no groundworks to install, small initial capital cost and can provide years of maintenance- free use.
  • the photoluminescent particulate comprises a rare earth strontium aluminate, such as strontium aluminate doped with Europium. Such materials have been found to exhibit an appropriate level of luminescence which can be sustained for several hours.
  • the second particulate medium is selected according to the type of finish required.
  • the second particulate medium comprises construction aggregate, such as stone chips, crushed glass, or a combination thereo .

  • the liquid sealant is applied using a roller, preferably at a coat weight of approximately 200 to SOOg/ ' m . This provides an easy method of application and an even result.
  • the liquid sealant may be any suitable flexible and quick drying solution.
  • the liquid sealant is an aliphatic polyaspartic comprising a resin and a hardener.
  • Such a sealant has been found to be very effective when used with the present invention, offering a quick-drying, flexible, resilient and UV and light stable coating.
  • the particulate media may be sprayed into the spray of liquid binding agent as it is applied to the ground surface. However, preferably the particulate media is sprayed towards the ground surface to be coated in the region of the newly applied binding agent. By doing so, the particulate media are prevented from rebounding directly off of the surface to be coated and is forced, by the pressure at which it is sprayed, into the binding agent. By forcing the particulate media into the binding agent, it is not necessary to wait for the particulate media to sink and settle into the binding agent under its own weight before the binding agent can be cured. Thus, a quick-curing binding agent may be used, reducing the time required for the coating to be applied .

  • the base layer 12 comprises a cured binding agent 16 into which particulate media 18 is set.
  • the sealing layer 14 comprises a cured liquid sealant.
  • the particulate media 18 comprises a mixture of a base particulate 24 and a photoluminescent particulate 26.
  • the base particulate 24 gives the surface coating 10 a rough, non-slip, hard-wearing finish, while the photoluminescent particulate 26 provides the illumination effect.
  • the sealing layer 14 seals the base layer 12 from water ingress.

  • the primer is applied by roller at a rate of 6 to 10 m 2 /L, and left for at least 90 minutes to cure. This forms a moisture barrier underneath the surface coating 10 to prolong the useful life of the coating 10.

  • the binding agent sprayer and the particulate media spraying apparatus thus also the nozzles 20 and 22 as shown in Figure 2, are separate and ideally operated by two operators, each operating one of the apparatuses and both sharing the weight of the unapplied binding material 16 and particulate media 18. This is particularly advantageous given the weight of material required for spraying large surfaces and also enables further applications of binding agent 16 or particulate media 18 to be made separately, as required.
  • the particulate media 18 is applied in a series of wave- like passes to ensure even coverage of the ground surface 100.
  • the blast nozzle 22 is held such that the particulate media 18 is expelled at an angle of approximately 30-45° to the horizontal.
  • the particulate media 18 is forced into the liquid binding agent 16, which is "bulked out” and coats the particulate media 18, providing a rough upper surface. Since the particulate media 18 is forced under pressure into the binder 16, it is not necessary to wait for the particulate media 18 to sink into the, binder 16 under its own weight, enabling a fast curing binding agent to be used.
  • the binding agent 16 may be of any suitable composition, provided it may be applied in spray form and cures quickly to provide an elastomeric, flexible and tough coating which is resistant to impact, tearing and abrasion.
  • the binding agent. 16 is a two-component polyurea hybrid formed from a polyurea hybrid isocyanate mixed with a polyurea hybrid polyol and applied using a plural component proportioning sprayer (such as the "Reactor E-XP2" available, from Graco, Inc., Minneapolis, Minnesota) attached to a spray gun (such as the "Plural Component Impingement Mix Air Purge Spray Gun” available from Graco, Inc., Minneapolis, Minnesota) .

  • the sprayer includes a heating unit by which the components of the binder 16 are heated to approximately 7Q-80°C to reduce the viscosity of the component liquids and the, curing time of the resulting polymer.
  • the exact temperature to which each component is raised is dependent upon the nature of the component and the ambient conditions and should be adjusted to ensure that the delivery is balanced. That is, the viscosity of each component should not be so different as to result in the delivery of unequal quantities of the two components.
  • the polyurea hybrid polyol component is heated to approximately 80°C and the polyurea hybrid isocyanate component heated to approximately 75 °C.

Once set, an air lance can be used to remove any loose particulate media 18 lying unbound on the base layer 12. If necessary, second and further passes can be completed in much the same way. The air lance is ideally used between each pass to prevent loose particulate media 18 from being oversprayed and thus causing a visible seam between adjacent waves. Following the application and curing of the base layer 12, the sealant is prepared.
  • the liquid sealant forming the basis of the sealing layer 14 is preferably a two-component aliphatic polyaspartic , namely "PU4827/1W” polyaspartic aliphatic topcoat, available from Leeson Polyurethanes Ltd. of Warwick, UK. This is formed from “PU4827/1W Part. A” resin and "PU4827/1W Part B” hardener and cures to form a transparent, flexible and UV stable coating.
  • the resin is mixed using a slow speed, high torque helical blade mixer until uniform.
  • the hardener is then added at a weight ratio of 1 part hardener to approximately 2.27 parts resin and mixed slowly for approximately 2 minutes until uniform.
  • the liquid sealant is applied on top of the base layer 12 using a non-absorbent roller at a coat weight of between 200 to 500 gsm, and left to cure for approximately 40 minutes to form the sealing layer 14. Once the sealing layer 14 has cured, the surface coating 10 is complete and can be walked on immediately.
  • the resulting surface coating 10 provides a hard-wearing, weather-resistant and non-slip finish that is flexible, tough, UV and light stable and strongly adhered to the underlying ground surface 100.
  • the photoluminescent particulate 26 absorbs UV radiation during the daytime and re-emits that radiation after dark, providing a gentle illumination for up to 20 hours. This illumination can show users where they are going and illuminate obstacles in their path, without contributing to light pollution.

  • the coating 10 could be used on any surface for which illumination is beneficial, for instance on footpaths, cycle lanes, building entrances and exits, or on steps.
  • the photoluminesecent material is provided as relatively large particles interspersed among the aggregate particles of the base particulate 24, illumination is provided as a plurality of discrete pinpoints of light against a dark background.
  • the overall visual effect is akin to looking at a clear night sky filled with stars. This is visually appealing as well as functional.
  • the photoluminescent particulate 26 is generally a pale colour, looking somewhat like pieces of white shell. When interspersed amongst the base particulate 24 it gives a slight speckling effect but the overall colour of the base particulate 24 is unchanged.
  • the intensity and duration of the illumination provided by the coating 10 depends on the intensity and duration of the sunlight to which the coating 10 is exposed, although even exposure to UV radiation on a cloudy day is adequate to cause the coating 10 to glow sufficiently for 12 hours.
  • the sealant layer 14 prevents any of the particulate media 18 becoming dislodged from the binding agent and provides extra weather and wear resistance. It is flexible, allowing it to bend rather than crack in the event that the underlying ground surface 100 moves, for example due to subsidence or the movement of tree roots. The sealant layer 14 also provides a barrier to water, reducing the occurrence of potholes and increasing the useful life of the coating 10.
