Abstract: Methods are disclosed for planarisation of a coated glass substrate by deposition of a silazane based layer thereon. Coated substrates according to the invention exhibit improved properties in terms of reduced roughness, lower haze and higher visible light transmission and the coated surface may be exposed to the external environment, for example as surface 1 or surface 4 of a double glazing unit. The resulting smooth surface is less susceptible to marking and scratch damage, and offers enhanced surface energy (improved hydrophobicity).
