A method of opacifying a spandrel glass surface, which is intended to be on the interior of a building, to stop light transmission by the glass which method comprises applying to the surface, which is intended to be on the interior of the building, a coating composition comprising an ultraviolet light resistant organopolysiloxane and an opacifier, wherein the opacifier is a mixture of carbon black and titanium dioxide present in the amount of 1 to 25% by weight and in a ratio of between 1:10 and 1:100 by weight carbon black:titanium dioxide, in an amount sufficient to provide to the surface sufficient opacity to light transmission, and curing the coating composition on the surface whereby the bond at the interface between the coating composition and the surface maintains its bond strength without peeling, fading or degradation after exposure to daylight for at least 20 months.
