D. Where sprayedon fireproofing is indicated as exposed finish in occupied spaces, repair substrate imperfections to ensure acceptable visual effect in texture of finish. Remove minor projections of substrate materials and fill voids which might telegraph through as visual texture variations.
E. Cover other work which might be damaged by fallout of overspray of fireproofing materials during spraying operations. Provide temporary enclosure as may be required to confine operations, protect the environment, and ensure adequate ambient conditions including temperature.
