Definitions

  • This invention relates to methods of providing surfaces with anti-slip characteristic, and to anti-slip surfaces themselves, the methods being of the kind which include the steps of applying to the surface a first coating of paint, distributing particles of mineral or other material on the coating before the coating has dried so that the particles sink partially into the first coating, then applying a second coating of paint over the particles and the first coating to lock the particles into the first coating with the particles projecting from the second coating.
  • Anti-slip surfaces and methods of the above-specified kind for providing them are known from US-A-4662972. Such methods include the step of spreading aluminium-oxide grit over a polyurethane coating while the coating is still wet so that the grit particles sink into the coating to an extent that one-half to two-thirds of each particle is embedded in the coating. Once the coating is dry, a thinner, second coating of polyurethane is applied to cover the first coating and encapsulate the exposed portions of the grit particles totally or at least sufficiently to leave just the sharp points of the grit particles projecting. The second coating traps any loose grit that is not well fastened in the first coating.
  • a method of providing a surface with anti-slip and retro-reflective characteristic, of said above-specified kind is characterised in that the method also includes the step of distributing retro-reflective beads on the second coating before the second coating has dried to sink partially into the second coating such as to be bonded thereto and effectively overshadowed by the projecting particles.
  • the particle size and the thicknesses of the two coatings of paint may be chosen in relation to one another, such that for the average-dimension of the particles, about one-third of each particle projects from the second coating.
  • the particles may be of aluminium oxide, silicon carbide (to give sharpness), zirconium (to give toughness), or plastics material (for example, for spark suppression), and may even be granules of rubber or cork (to give resilience and/or compliance). They may be applied by spray or a controlled gravity-feed system or by an electrostatic method.
  • the retro-reflective beads may be added by gravity feed or otherwise (for example by spray) either during application of the second coating of paint, or immediately afterwards before that paint has set.
  • the beads as bonded to the surface by the second coating are preferably of significantly smaller dimension than the particles used. They are preferably no more than two-thirds the size, so that they will be readily overshadowed by the projecting particles.
  • Retro-reflective beads tend to present a slippery surface, especially when wet, but this does not have deleterious effect where they are effectively overshadowed, as with the method of the present invention, by the projecting particles.
  • the beads may be interspersed between the particles to maximise the anti-slip characteristic and afford them good protection against dislodgement.
  • they may be similarly, effectively overshadowed where they are included in strips or other narrow areas of the second coating which are surrounded closely by projecting particles but which are themselves free from those particles.
  • the paint used which may be the same for both coatings and may contain fillers and/or pigments, may be an epoxy-resin based paint.
  • the method of the present invention may be successfully applied economically and readily to paths, roadways, passageways, decks (for example on ships and oil platforms), helicopter landing pads and airfield runways and taxiways.
  • an anti-slip surface in which the surface involves a first coating of paint that has particles of mineral or other material embedded within it to project from it, a second coating of paint covers the first coating and the projecting particles to lock the particles in the first coating, and the particles project through the second coating, characterised in that retro-reflective beads are bonded partially into the second coating to project therefrom, and that the beads are effectively overshadowed by the projecting particles.
  • Figure 1 shows a section through a two-coat anti-slip paint system that has been applied to a blacktop (for example, bituminous or tar macadam) or concrete surface of a path, roadway or airfield runway or taxiway, in accordance with the present invention.
  • a blacktop for example, bituminous or tar macadam
  • the traffic surface may be a metal or other deck for helicopter use on a ship or oil rig.
  • the swept and cleaned traffic surface 5 is given a first coat 6 of an epoxy-resin based paint to a thickness of 0.3 mm; in the case illustrated, the surface 5 has been previously primed with the paint to the extent necessary to enable the first coat 6 to be established without absorption into its sub-surface 7. While the paint of the first coat 6 is still wet, mineral particles 8 having a 16-mesh grit size are applied evenly over the paint to sink into it, at a rate of some 1 to 1.5 kg/m2.
  • a second coat 9 of the paint is applied to a thickness of 0.3 mm, over the first coat 6 to lock in the particles 8.
  • glass beads 10 are distributed evenly over it to sink in partially, and to be firmly bonded into the coat 9 when it dries.
  • the beads 10 which are at least nominally spherical, have diameters generally within the range 0.18 to 0.40 mm, and are applied at a rate of some 400 to 500 g/m2. They are interspersed between the significantly larger particles 8 to nestle down between them in the second coat 9. The beads 10 are accordingly protected by the particles 8 and overshadowed shielded by them so as not to have any effect on the overall anti-slip characteristic of the surface.
  • the helicopter landing pad is a square area 11 marked with the conventional symbol consisting of an area 12 delineating the letter 'H', and an area 13 that delineates an enclosing circle.
  • the whole of the square area 11 has the two-coat anti-slip surfacing system as provided by the mineral particles, but it is only the areas 12 and 13 that also include glass beads in the manner described with reference to Figure 1.
  • the resultant retro-reflectivity of the areas 12 and 13 make them distinctive, but they are also distinguished from their surrounds within the area 11 by use of coloured paint for the second coat or for both the first and second coats.
  • strips or other narrow areas of the anti-slip surface may be masked so as to be left clear of the mineral particles, and then subsequently filled with beads to give that strip or other area retro-reflectivity.
  • This latter technique may be adopted especially where narrow lettering or other marking is to be inset into the anti-slip surfacing, and is to be very clearly visible at night.
  • An example of application of this technique to the marking of an airfield taxiway with an arrow and box symbol will now be described with reference to Figure 3.
  • Figure 3 shows part of the taxiway with its anti-slip surfacing broken away to reveal the concrete base surface beneath.
  • the concrete base 14 of the taxiway is surfaced with a two-coat anti-slip system 15 that is inset with strips 16 and 17 of glass beads which delineate an arrow and an open-box symbol respectively.
  • the anti-slip system 15 is applied by a two-coat process comparable with that described above with reference to Figure 1, after the concrete base 14 has first been treated with a primer to improve adhesion of the system 15 with it.
  • the first coat of the paint system has been applied to cover the base 14, the areas to be occupied by the strips 16 and 17 are masked off in order to keep them clear of the mineral particles distributed on the first coat in the process.
  • the masking is removed and the second coat of the system is then subsequently applied to cover the whole of the first coat, including the areas (for the strips 16 and 17) that are free of mineral particles.
  • the beads within the strips 16 and 17 are of significantly smaller dimension than the mineral particles used for the anti-slip surfacing, so that the beads are protected (by being effectively overshadowed) to a certain degree by the mineral particles surrounding them in the surface.
  • This protection is greater the narrower the strips 16 and 17, and provided the strips 16 and 17 are kept narrow, the anti-slip characteristic of the surface elsewhere can be maintained across the strips 16 and 17 without significant loss.
  • the strip-width is desirably significantly less than the smallest 'footprint' likely to occur on the surface.
  • the widths of the inset strips 16 and 17 of glass beads are significantly less than the widths of the narrowest tyres that are likely to be used on that surface.
  • a significant proportion of the ground-contact area of that tyre overlaps the strip so as to remain in contact with the mineral-occupied surrounds of that strip and be afforded adequate anti-slip restraint.
