Zusammenfassung:	Methods of treating a cured porous inorganic; coating include contacting the coating with water vapour or a combination of water vapour and base, wherein the coating prior to curing includes a coating composition having particles with a core which is hollow or which comprises an organic polymer composition and a shell formed of an inorganic oxide. The shell has a thickness in the range from 2 to 75 nm and has at least one and no more than five enlarged pores, each enlarged pore having a diameter of between 5 nm and 300 nm.
