A method of coating sheet material with a coating composition comprising particulate solid material suspended in a liquid carrier, wherein the coating composition is applied to the sheet material as a foam and subsequently dried, the air content of the foam being such that the viscosity of the coating composition is greater in its unfoamed state than in the foamed state in which the composition is applied.
