How To Seal French & Double Doors

Apply Flood Paste (cartridge) directly into the gap between the threshold and the bottom of the doors, between the doors, around the lock sets or door handles, and all seams. Also where single panes of glass meet the door and/or where multiple panes meet the mullions. Use gloved finger or Flex Gap Filler tool to push Flood Paste into seams and smooth out.

Apply Flood Paste along the front, bottom, sides, and corners of the threshold, including screw holes. Push the Flood Paste in and smooth it out with gloved finger or Flex Gap Filler tool.

Apply Flood Paste along where the doorframe meets the casing as well as where the casing meets the exterior wall. Push the Flood Paste in and smooth it out with a gloved finger or Flex Gap Filler tool.

Cut a small square of Flood TAPE, peel the backing, and place over keyhole, pressing firmly. Next, completely cover with Flood Paste and smooth out with gloved finger or other tool.

Cut the Flood Tape to size. Remove the backing only a few inches and press the exposed adhesive side to the top of the area being sealed. Continue to pull off the backing, pressing the Flood Tape firmly with a gloved hand or squeegee to smooth out any creases or wrinkles.

Do not apply Flood Tape around corners, contoured surfaces, or irregular shapes, as they can create air pockets and allow water to enter.

Using a putty knife, remove the Flood Paste (Sleeve) from provided tray and apply an even coat on top of the Flood Tape, covering the edges (excluding keyhole) with each coat being wider and overlapping the previous one.

If you applied Flood Protection Paste in thin, even layers, you should expect it to be dry to the touch in two to six hours. Next, we recommend applying additional coats of our Flood Protection Paste as needed.

Follow the same application process as the first layer, but each individual coat that you apply should be wider and overlap the previous layer of Flood Protection Paste and Tape.

Once the doors have been sealed and are completely dry and you already have multiple layers of Flood Protection Paste, we recommend using our Flood Protection Liquid as an additional layer of protection.

When applying our Flood Protection Liquid, use your brush and apply it directly on top of our Flood Protection Paste and Tape, making sure you overlap your final coat, this will help cover any pinholes or openings that you can't see. Don't forget the seal around the door handle and lock.

Remember you want to make sure all the flood protection products are fully cured before a flood arrives.
