Abstract
Selected surfaces of a cellular polymeric foam surface finishing pad are heated to cause the surface cells to partially collapse or to fully collapse and glaze over. The selected surfaces may be the planar pad faces or may be formed in one or more depressions formed in the planar faces. The areas of partially collapsed cell structures in the operating face of the pad provide a slow down in the rate of polish or compound absorption, increasing the effectiveness of the finishing process. The fully collapsed cell glazed surface on the rear attachment face of the pad prevents the migration of moisture through the pad to the pad attachment mechanism.
