PART 3 - EXECUTION
3.01 Examination
  1. Examine surfaces and report unsatisfactory conditions in writing. Do not proceed until unsatisfactory conditions are corrected.
  2. Verify surfaces to receive spray insulation to determine if priming/sealing is required to insure bonding and/or to prevent discoloration caused by migratory stains.
3.02 Preparation
  1. Provide masking, drop cloths or other satisfactory coverings for materials/surfaces that are not to receive insulation to protect from over-spray.
  2. Coordinate installation of the sprayed cellulose fiber with work of other trades.
  3. Prime surfaces as required by manufacturer's instructions or as determined by examination.
3.03 Installation
  1. Thickness will be determined as the minimum thickness measured as per ASTM E-605 field test procedure.
  2. Install spray applied insulation according to manufacturerÕs recommendations
  3. Cure insulation with continuous natural or mechanical ventilation.
  4. Remove and dispose of over-spray.
3.04 Protection
  1. Protect finished installation under provision of Division 1
3.05 Schedule
Provide a schedule when insulation requires listing by color, insulation value, NRC values and attributes.
