PART 3 – EXECUTION
Examine surfaces scheduled to receive insulation for voids, projections, foreign substances on surfaces, lack of caulking at plates, or other items, which might interfere with integrity of complete wall system. Examine surfaces and report unsatisfactory conditions in writing. Do not proceed until unsatisfactory conditions are corrected.
Assure that rough plumbing, electrical conduit and boxes, and other items required to penetrate the sprayed soundproofing are installed before applying soundproofing.
Spray-force material into all cracks, holes, seams; seal around electrical receptacles, telephone/ television jacks, ducts and plumbing.
Provide masking, drop cloths or other satisfactory coverings for materials/surfaces that are not to receive insulation to prevent damage from over-spray.
Coordinate installation of the sprayed cellulose fiber with work of other trades.
Thickness will be determined as the minimum thickness measured as per ASTM-E605 field test procedure.
Install spray applied insulation according to manufacturer’s recommendations. Apply material with specially designed nozzle using pressure recommended by the manufacturer.
Cure insulation with continuous natural or mechanical ventilation.
Remove and dispose of over-spray.
Protect finished installation under provisions of Division 1.
