Flex Seal – Does It Work?

The Flex Seal makes some pretty bold claims. In the commercial they replace the bottom of a boat with a screen door and cover it with the Flex Seal, and the boat stays afloat.

But we don't want you to sink money into a product that may not work. So we called on mr. fixit himself, Bobby Carr with greenville handyman services.

He set up 5 different tests that mimic the commercial.

He drilled holes in a gutter and covered it with the Flex Seal, repeated the drill on a shingled roof, patched up a cracked plant holder, sealed a mesh bowl, and even covered the screen door bottom of our makeshift boat.

On day one of testing Carr remarks, "it's got a good name, liquid rubber, so it's definitely becoming very sticky, tar like rubber base."

Fast forward a few days to let it dry, and we're ready to see if the flex seal lives up to it's image.

Carr tests out the gutters first by spraying water directly into the "repaired" gutter. "This is direct application of water to the products and it's not leaking at all."

The pot also holds up, and after seeing the thick layer covering the mesh bowl, I was even ready to take a chance by holding the bowl above my head. I stay dry.

But the results weren't as promising for the roof test.
