Abstract
A method for coating the interior of a cylindrical surface comprising depositing on the interior or a rotating cylindrical surface a dry hydraulic cement composition and applying to the dry cement coating which is held stationary on the interior cylindrical surface by the centrifugal force of the rotating cylinder an aqueous composition and allowing the cement to harden to provide a coating having no tendency to slump or sag in the wet condition.
