Flex Seal Review: Your Infallible Sealing and Caulking Repair Tool

I have been watching the advert of Flex Seal on television and to be honest, I wasn’t interested at all about using it though the pipes of the washrooms were leaking and so was the roof. Even though I was just hoping that they don’t start dripping so that I don’t have to take an off from the office and spend a fortune, which I don’t have in the first place, to repair them. But soon it happened and it happened in the dead of night, when the odd voice of tiny droplets falling from a height woke me up. Mind you, those drops wouldn’t mean anything if they don’t belong to you or aren’t caused due to your negligence but if they are in your house, their sound can be earth shattering especially in the silence of night and when you are trying to ignore their sound and try to fall asleep.

What is Flex Seal?

In simpler words, it is a liquid rubber that is filled in a pressurized tin can. In professional, it is a proprietary and patent-pending formulation in a liquid form that can be used on any surface and which, when dried upon turns out to be a robust, flexible, water-proof and rubberized coating. It creates a moisture-proof, water-proof and air-proof as well as non-slip surface. You can treat a surface to protect it from moisture, UV degradation, extreme temperatures and natural wearing. You can treat the surface with steel wool or sand paper before the adhesion. Depending on the coats used, the coverage may vary. For instance, approximately 20 square feet can be filled with 1 large 16oz and 1 Jumbo 32oz can be used to treat 40 square feet. However, you need to make sure that surface is completely dry and cleaned. If the surface is moist or dry, it can take time to fill.

You can roll, dip or brush on liquid to the surface. However, it is recommended that if you want to fill a large gap or hole, it is always better to brush on or roll over for a quick application. For additional coats, you should wait for at least 24 hours. You can also make dip the surface making a swirl motion. You can drip back the surface in the can to remove excess liquid. Just hang the surface with the help of a clip to let it dry. You can also fill holes and cracks with the help of Flex Seal. Just pour on the liquid and let it reach the corners, which are otherwise difficult to access.

Upon drying, the Flex Seal liquid takes on black color, which can be painted to match the surface. This is one more advantage that the liquid has over other rubber sealants that come in darker and hard to conceal colors. With Flex Seal, when painted with the matching surface, it is in fact, difficult to tell the treated and original surface apart.

Moreover, Flex Sealant can be used to cover any surface, be it moist or soft whereas other rubber sealants have limitations and can’t be used on surfaces that have been exposed to heat, water or moisture. All you need is clean and dust-free surface to apply Flex Seal.

Reports of Flex Seal Bottles Catching Fire and Other Issues Reported by Users:

It was very important that we discuss this topic as the maker of Flex Seal was under fire literally due to its cans catching fire and setting the homes ablaze. However, it is very important to understand Flex Seal is liquid rubber that is filled in cans using lots of pressure. So, you are supposed to keep it in cool environments and away from direct sunlight and heat sources. Ensure proper storage of product and you won’t have a thing to worry about. If possible, try taking the surface outdoors and if it is a leaky faucet or pipe that can’t be taken outside, make sure there is an arrangement of proper ventilation.

Other than this, the users have complained about the product being not effective enough as even after using four coatings of the Flex Seal, the leakage wasn’t fixed and the problem remained as it is. First thing, you need to maintain proper intervals between spraying. Too much spraying won’t solve the leakage. Proper application of the product would. There should be at least 12 to 14 inches of distance while spraying and you should let the first coat dry fully before you proceed to the next one. Usually, it takes up to 4 hours to dry a coat completely. With each extra coating of Flex Seal, the time increases. The idea is to take notice of holes and cracks on the surface. As you apply a coat on the surface, the size of holes and cracks becomes smaller. So, ideally, you should spray on until the holes are completely disappeared and the cracks are fully filled as well as covered.​

There have also been complains about floors and other items such as furniture and pipes being ruined while using Flex Seal. Folks, you need to be careful with Flex Seal the way you would while using other handy repair tool or rubber sealant.
