Description

The Flex Seal Family of Flood Protection Products are specifically designed to work TOGETHER to create multiple layers of super-strong, waterproof protection, and to be easily removed after floodwaters recede. They can help slow down or even stop water from entering structures. Floods are now the leading natural disaster on the planet. Help defend your home from rising water by applying our Flood Protection Paste, Tape, Spray, and Liquid to every opening of your home where floodwaters could enter. All of our Flood Protection Products have been designed for simple removal once floodwaters recede. When used in combination and as directed, our Flood Protection products have been independently verified by UL Solutions to hold back 3ft of water for 14 days on gaps up to ½ inch.* All of our Flood Protection products come with a comprehensive application directions booklet, as well as a link to detailed “how-to” videos, guided by Flood Protection pros. Our primary Flood Protection product. Should be used as a base coat for your first layer of protection. The cartridge nozzle allows you to target specific areas that need to be sealed. Use on windows, doors, garage doors, and all types of seams, casings, thresholds, conduits, vents and ducts, keyholes, and more. Use on larger areas, flat surfaces, or directly on top of our other Flood Protection products. Great for basement widows, pet doors, crawlspaces, seams, windowsills, foundation cracks, and more. Use primarily as a final layer of protection to help seal any small pinholes or openings that may have been missed. Brush a generous amount directly on top of our other Flood Protection products. Each coat should be wider and overlaps previous layers of our Flood Protection products. Use on smooth, flat, even surfaces, and always in combination with our other Flood Protection products. Do not bend our Flood Tape around corners or over irregular shapes. Apply Flood Paste directly on top of the Flood Tape and its edges, making sure that each coat is wider and overlaps the Flood Tape. IMPORTANT INFORMATION Always follow State and Local weather advisories and evacuation orders. Depending on the age and type of construction, there may be areas that cannot be seen or sealed. Unsealed porous surfaces may seep water during extended underwater exposure. Not designed to protect against extreme winds, water pressure, flying or floating debris. Not intended to stop water from flash floods or if there is structural damage to the building. For best results, use our FLEX PASTE FLOOD PROTECTION IN A CARTRIDGE as the base coat for the first layer of protection, and our FLEX SEAL LIQUID FLOOD PROTECTION as a final coat to help seal openings that may not be visible. *For complete Flex Seal Family of Flood Protection Products UL Verified details, visit: Verify.UL.com V114667, V165781, V855276

Flex Seal Spray Flood Protection Review for Coop Interior
Style: 10 oz
I've got to share a little trick I've used with the Flex Seal Spray Flood Protection. You see, I've been concerned about droppings damaging the wood inside my chicken coop, and this stuff has been a real lifesaver. Pros: Waterproofing: Flex Seal lives up to its name when it comes to sealing out moisture. I sprayed it on the coop's interior walls and floor, creating a waterproof barrier that keeps the wood safe from any mess. Durable: This stuff forms a strong, flexible barrier that doesn't crack or peel, even when faced with the constant wear and tear of a chicken coop. Easy Application: Applying it was a breeze. I didn't need any special equipment, and it adhered well to the wood surfaces. Cons: Ventilation: While it's great for keeping moisture out, it's essential to ensure proper ventilation in the coop to avoid any buildup of fumes. I made sure to have adequate ventilation in place. Coverage: Depending on how large your coop is, you might need multiple cans to ensure thorough coverage. In the end, using Flex Seal Spray Flood Protection for my coop's interior has been a smart move. It's added a layer of protection to the wood, helping it withstand the challenges of housing chickens while making cleanup a breeze. Plus, it's just one more step toward my goal of ensuring a comfortable retirement, knowing my investments are well-protected – whether in the stock market or in my coop! ... show more

WASTE OF MONEY, DOES NOT WORK AS DESCRIBED
Style: 10 oz
I've been using Flex Seal products for years but had never needed flood protection before. I thought this was going to come out a little thicker, filling in gaps and cracks. NOT. This product comes out in a very thin liquid, making it impossible to stay in place. You spray it, and it just slides right down. The spray is extremely wide. Whatever you're spraying, you'll have to cover everything behind, beside, above and below it. Since it doesn't actually stay where you spray it, expect huge globs of it to drop off underneath whatever you spray. Doesn't matter if you wear gloves, this wide spray gets on EVERYTHING. Fumes are noxious, will need LOTS of ventilation if you do buy it. ... show more

Awful. Do not buy.
Style: 10 oz
This stuff sprays in a very wide path. Which makes useless for a normal seam. Even worse is trying to get off. Absolutely difficult!!!!

Not what I expected
Style: 10 oz
I thought this was the flex seal that puffed up when sprayed to fill a hole. It wasn't. I located the other spray & got the project finished with & checked off of my to-do list.

Not impressed
Style: 10 oz
This product is supposed to be waterproof, but I put it on the inside of a flower pot to keep the water from coming through. Did not work. Not impressed with the product.
