Seal Your HVAC Ducts with Precision for Optimal Performance
Rigid Fiberglass Air Duct:
  1. Assemble Sections: Follow the manufacturer’s instructions to connect the fiberglass air duct sections.
  2. Apply Base Coat: Apply a 3-inch wide, 10-mil thick band of duct sealant to the duct board.
  3. Embed Fiberglass Scrim: Place a 5-mil fiberglass scrim with a 20×10 weave into the wet sealant.
  4. Apply Top Coat: Apply another 10-mil coat of duct sealant over the embedded scrim.
Flexible Air Duct/Metal Duct Application:
  1. Prepare Joints: Using a brush or putty knife, apply duct sealant to a minimum thickness of 20 mils to the male section of the spiral duct or to both fittings in a rectangular duct.
  2. Join Sections: Quickly join the sections while the sealant is wet (within approximately 15 minutes).
  3. Secure with Screws: Secure the joint using sheet metal screws placed as close to the joint head as possible (approximately 1/2 inch or less).
  4. Seal Exterior: Apply a 3-inch band of duct sealant to the outside of the assembled joint, covering the head and sheet metal screws.
  5. Allow to Set: Let the sealant set for approximately 48-72 hours.
  6. Pressure Test: After the sealant has set, pressure test the system for leaks to ensure a tight seal.
Tips for Optimal Results:
  • Follow Manufacturer’s Instructions: Always refer to the specific instructions provided by the duct sealant manufacturer.
  • Work Quickly: For flexible duct and metal duct applications, ensure prompt joint assembly while the sealant is wet.
  • Use Quality Sealant: Choose a high-quality duct sealant designed for the specific application.
  • Properly Secure Screws: Ensure that the sheet metal screws are securely fastened to prevent leaks.
