PART 3 - EXECUTION

3.1 PREPARATION

3.1.1 All surfaces to be insulated shall be free of dirt, oil, wax, rust, loose mill scale, paints/primers, or any other foreign matter that may impair adhesion of the acoustic/insulation material to the substrate. Where necessary, cleaning of the surfaces to be sprayed shall be the responsibility of the Structural Steel Erector of the General Contractor.

3.1.2 Compatibility of Surfaces: The project architect shall determine whether the painted/primed asbestos lock down substrates are compatible with the sprayed acoustic/insulation material and will facilitate complete and proper adhesion.

3.1.3 SOUND-PRUF™/THERMAL-PRUF™ will adhere to most clean structural surfaces, however, the use of a primer coat may be necessary on painted/primed asbestos lockdown surfaces. Contact manufacturer for further compatibility information.

3.1.4 Clips, hangers, support sleeves, and other attachments shall be in place before application of acoustic/insulation material.

3.1.5 Rolling compounds and lubricants used in the manufacture of steel deck and steel siding may impair adhesion of acoustic/insulation material to the substrate. Steel deck and steel siding specifications shall call for the deck/siding manufacturer to supply deck/siding free of such compounds of lubricants. Ducts, pipes, or other suspended matter shall not be installed until acoustic/insulation application is completed.

3.1.6 Metal siding use in the pre-engineered steel building industry are coated with a wide variety of interior (backer) finishes. Certain types of backer coatings may require the applications of a primer to ensure adhesion of sprayed acoustic/insulation material to the substrate. The project architect shall determine the type of backer coating used, and compatibility with the acoustic/insulation material. Contact American Sprayed Fibers, Inc. for complete information on backer coatings, compatibility, and acceptable acoustical/insulation primers.

3.1.7 The project architect shall call for a galvanized interior (backer) coating in steel siding specifications if possible.

3.1.8 All roofing applications shall be completed prior to application of acoustic/insulation material to the underside of roof decks. All roof traffic shall be prohibited upon beginning of acoustic/insulation applications, and until the acoustic/insulation material is fully cured and dried.

3.1.9 All concrete work shall be completed prior to application of acoustical/insulation to underside of steel deck.

3.1.10 The applicator shall provide all necessary drop cloths, masking, and coverings, to prevent acoustic/insulation over spray.

3.1.11 Application of acoustic/insulation material shall not begin until the applicator and general contractor have inspected the surfaces to be sprayed, and performed bond strength test necessary, to determine these surfaces acceptable to receive acoustic/insulation material.

3.1.12 When outdoor temperature is below 32° F, substrate and ambient temperatures of 35° F or higher must be maintained for 24 hours before, during, and 24 hours after application of the acoustic/insulation material. If necessary, the general contractor shall provide heated enclosures to maintain proper temperatures for job progress. Drying time for temperatures about 32° F depend on thickness sprayed.

3.1.13 Beginning of installation means applicator accepts existing substrate conditions, and environmental conditions.
