Our Flood Paste in a Sleeve starts out as a thick, paste that can be pushed deep into all types of openings and hard-to-reach areas. It dries to a strong, flexible, rubberized coating. It seals out water, while remaining completely flexible. Once floodwaters recede, our Flood Paste can be easily removed. Flood Paste in a Wrapped Sleeve should be used on larger areas, flat surfaces, or directly on top of our other Flood Protection products. Use on basement widows, pet doors, crawlspaces, seams, windowsills, foundation cracks, and more. When applying our Flood Protection Paste in a Sleeve, it's important to push the Flood Paste deep into all seams and openings. This will help create a watertight seal. Always be cautious of any sharp objects that may cause injury. Color: Yellow.
