Flex Seal Product Test: Can it Keep a Barrel from Bursting?

The sun is finally shining today here in Minnesota. It’s been unseasonably cool, cloudy and rainy for the last several days, and everything outdoors is wet and soggy. As you can see in the first photo below, our rain barrel was overflowing and threatening to burst at one of its seams. We recently received a can of Flex Seal to review, and sealing the seam seemed like a good test of this liquid rubber sealant in a spray can.

First, I masked off the affected area. Then I followed the directions on the can, shaking vigorously for about a minute before holding the can about a foot away and applying several thin coats in a sweeping motion. Very fast and easy to apply. I let it dry before removing the masking to reveal a neat and clean repair that will hopefully last a long time. Flex Seal is advertised as useful for patching roofs, foundations and gutters, as well as sealing flashing around skylights, vents and chimneys. Based on this simple test, I’m sure I’ll find many more uses for Flex Seal around our 100 year old home to stop leaks and keep it watertight. Here’s where to order.
