Very useful around the house

DGS May 11, 2026

I always keep a can around the house just in case I need it. Each time I used it it solved my issue. I mainly use it in drainage pipes for tubs. showers. bathtubs, sinks where there is no water pressure. I used it in wet condition and it performs perfectly. Months and years later it performs better than my expectations. It is very durable,

Seal

Gnirad April 7, 2026

Not sure what happened with the item I got but it was caked hard and hard to work with not sure if it was how it was stored but it was not what I had expected. It was very difficult to apply to the surface where I needed it , as it was overhead and because of it no being as pasty as I had anticipated made the project harder than it should have been A picture of the product received is submitted

it was solid as a rock

Lauri August 7, 2026

I bought this several times and it always worked well and this time it arrived and the paste was solid as a rock. very disappointed, I really needed it and am worried to order more if it keeps happening.

Can I get a good can, please?

Larie October 3, 2026

My paste arrived promptly, however, the can was damaged. When I opened it, the paste was hard already. I have rated this a two because I know flex seal has great products, but whomever does their storage or shipping, sucks.

Complaint

Julie April 14, 2024

I bought the Flex Paste in March of this year. We opened it yesterday (April of this year). There was a ring of dried paste 1/4 of the way down. It was very difficult to get the good paste out from below the ring. We would have been able to finish our project if not for the dried paste. I don’t appreciate spending $15 and not being able to use all of the product.

Most of it had solidified and was unusable.

SaraLinda December 16, 2025

Arrived mostly solidified with a central area of barely useable semi solid rubber. Very disappointed.

Rock Hard on arrival

Florida July 18, 2023

The item arrived with 1-1.75” of hardened product. The top layer was almost impossible to penetrate. I was able to make a small hole with a drill bit and scoop out 2-3 teaspoons. My worst experience with Flex seal.

Not very good

Gerthy October 30, 2023

Open the container to use it for the first time today half the product has already hardened. Not pleased at all. I can only use the middle.
