Review: Affordable Protection That Really Works! - After our house flooded last year, we looked into professional flood barriers, but the cost was outrageous. That’s when we tried Flex Seal Liquid—and honestly, it was a lifesaver. We applied it along the base of our foundation and around vulnerable door frames, and it created a strong, waterproof barrier that gave us real peace of mind during heavy rainstorms. The application was straightforward—brush or roll it on, let it cure, and you’re set. It dries into a thick, flexible coating that feels durable yet not brittle. When the next big storm hit, we had no water seeping inside where it used to pour in. It’s not a complete replacement for professional flood systems, but for the price, it’s an amazing layer of protection. If you live in a flood-prone area and need a cost-effective solution, I can’t recommend this enough. It’s not just hype—Flex Seal truly helped protect our home when we couldn’t afford expensive alternatives.

### ⭐ Don’t Buy This - Can’t work with it, can’t remove
*by R***T on October 11, 2024*

This product never did dry ( applied over the Flex Tape to prevent predicted 6-8 ft storm surge from Milton as recommended ) and it will cause you to repaint or restain any wood item it comes in contact with. Took 4 1/2 hours to remove it from 2 French doors and 1 sliding glass door. The entry door is mahogany and the lower half must be restained. In addition- perhaps due to high humidity- the product becomes thick like sludge and the product isn’t useable when the can is still 1/2 full. Did it or the Flex Seal Tape work, you wonder? The storm surge never happened and saying we are grateful for this is an understatement, as we did flood from hurricane Ian and learned about the Tape after the fact. Next hurricane we will use more Tape and keep our fingers crossed.
