Measure the opening you want to seal. Cut a piece a plywood large enough to overlap the entire opening. Apply a generous amount of the flood paste to the wall surrounding the entire opening.

Firmly press the plywood to the wall, covering the entire opening. The Flood Paste should squeeze out between the plywood and the wall. If not, you’ll need to apply more Flood Paste.

Brace or hold the plywood in place for a few minutes until it stays in position. Once in place, use a gloved finger or gap filler tool to push the Flood Paste into the seam between the plywood and the wall and smooth out, making sure there are no gaps or openings.

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.

Once the plywood is sealed and completely dry, and you already have multiple layers of Flood Protection Paste, we recommend using our Flood Protection Liquid as additional layers of protection.

Brush a generous amount of Flood Liquid directly on top of the plywood, as well as the surrounding areas, making sure to overlap where the Flood Paste meets the wall.

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 Liquid.

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