Install fill materials for firestopping by proven techniques to produce the following results: 1. Fill voids and cavities formed by openings, forming materials, accessories, and penetrating items as required to achieve fireresistance ratings indicated. 2. Apply materials so they contact and adhere to substrates formed by openings and penetrating items. 3. For fill materials that will remain exposed after completing the Work, finish to produce smooth, uniform surfaces that are flush with adjoining finishes. 3.4 CLEANING AND PROTECTION A. Clean off excess fill materials adjacent to openings as the Work progresses by methods and with cleaning materials that are approved in writing by penetration firestopping manufacturers and that do not damage materials in which openings occur.
