Roughing-up
A term applied to the first process when covering the bricks of a loam-mould with loam. After the bricks are set three fourths of an inch back from the sweep-board, the coarse, wet loam is rubbed vigorously on the bricks to make it adhere firmly, a little more than enough being spread over. The sharp edge of the sweep-board scrapes off the surplus, leaving a rough face--hence the term. This rough face is afterwards made smooth by the application of fine loam, over which the sweep-board is again drawn in the opposite direction. See BRICKING-UP; LOAM-BOARD; SKINNING-LOAM.
