Conventionally, paints which are formulated for use as markings on roads have also been used as markings on airport runways but have been found unsatisfactory since airport runway markings have special requirements. The present invention provides a high opacity thin coat concept airport runway marking paint comprising 20-60% by weight of titanium dioxide in the paint or higher within the critical pigment volume concentration (C.P.V.C.), extenders such as Barium Sulphate, Laminar Talc, Calcite or Dolomite used alone or as blends thereof, binders such as Plasticised Chlorinated Rubber, Acrylated rubber, Epoxy, Polyurethane or emulsified resins and an anti-skid aggregate comprising crushed glass particles or calcined Aluminum oxide or the like. Airport runway markings need frequent maintenance re- application of paint in order to obliterate the black marks left after contact with aircraft tyres. The high opacity paint has the advantage that it can be sprayed on at very thin film thickness thereby minimising the tendency of the build up of thick smooth film to potentially hazardous levels.
