HOW TO SEAL

DUCTS & VENTS

IMPORTANT: When sealing a vent or duct, do NOT use any appliance or xture that leads to the

vent or duct being sealed. Example: don’t use your dryer while (or after) your dryer vent is sealed.

STEP #1 – APPLY FLOOD PROTECTION TAPE

1. Make sure the areas being sealed are clean, dry, and free of grease, oil, dirt, and debris.

2. Unroll Flood Tape and cut a piece a little larger than the opening you’re going to cover. Multiple

pieces may be required to seal the opening.

3. Remove the Flood Tape backing and apply directly over the vent or opening.

4. Using your gloved nger or squeegee, press rmly to smooth out any folds, creases, or wrinkles.

STEP #2 – APPLY FLOOD PROTECTION PASTE IN A CARTRIDGE

1. Cut the nib o the Flood Paste (cartridge), screw on nozzle, cut the nozzle to the desired bead

thickness, and apply Flood Paste directly on top of and around the Flood Tape.

2. Use your gloved nger to spread the Flood Paste, making sure you cover the entire opening.

3. Apply Flood Paste (cartridge) to where your duct meets the wall.

4. Use a gloved nger or Flex Gap Filler tool to push the Flood Paste into the seam and smooth it out.

5. Let dry to the touch (2-6 hours*).

6. Apply additional coats as needed and make sure each coat is wider and overlaps the previous coat’s

edges. Let each coat dry to the touch before applying the next coat.

STEP #3 – APPLY FLOOD PROTECTION SPRAY OR LIQUID

1. If using the Flood Spray, apply a light coat using an even sweeping motion from 8” to 12” from the

surface. If using the Flood Liquid, brush a generous amount over the entire area. Be sure you’re

covering the opening and the area where the vent duct meets the wall. Using the Flood Spray or Flood

Liquid will help seal any small openings or pinholes that may have been missed.

2. Let dry to the touch (Spray: 30-60 minutes / Liquid: 3-6 hours)*.

3. Using the same process as above, apply additional coats as needed, with each coat being wider and

overlapping the previous coat. Let each coat dry to the touch before applying the next coat.

*Dry times may vary based on temperature, humidity, and thickness of applied layers.
