Great Leak Stopper

Anonymous April 29, 2022

A couple of weeks ago I received my Flexseal product. I used it to try and stop a persistent basement sewer drain pipe leak that ran from a sewer drain pipe from the house through the basement's cement wall outside to my septic tank. Unfortunately, in the past , everything I tried failed to stop the small leak. However, after I smeared it with the Flexsea, as best I could, and after three or four days I was delighted to see that it no longer leaked. I was delighted to see that it no longer leaked! Great job.

Flex seal has a new purpose (or two)

Anonymous November 6, 2022

Two different uses of the Flexseal paste I have never seen advertised. 1) I have used Flexseal to repair bicycle inner tube punctures rather than a cheap patch. Normal prep of the tube and a coating if the paste is all that's required tor an air tight seal and no issues. As a competitive cyclist, I have lots of training rides in less than ideal conditions resulting in several punctures. I'll usually collect several tubes and spend very few minutes affecting the repairs. 2) I'm currently replacing pool decking and installing composite decking over a concrete and paver pool deck. Over time, the pool deck has shifted and cracked and the surface is uneven and broken in places. I use Flex seal to help anchor the ends of the composite decking to the existing surface to keep the surface level and secure. Works well.

Flex Paste experience

Mac1 February 18, 2023

I bought both Flex Seal spray and Flex Paste at the same time. The Flex Seal spray worked great, and turning the can upside down and spraying until it clears after each use allowed me to use the spray, a little at a time, over a 2 week period without any clogging. The Flex Paste came with about an inch thick ring of the paste hardened at the top. Using the suggestions of leaving the remaining paste level and resealing with the protective foil and silica pack allowed me to use a little at a time over a two week period without any further hardening or waste. Luckily I didn't need that amount that was hardened when it was delivered. But yeah, it worked great layering it on every other day, allowing each layer to dry between coats.

Don't Get What You Pay For

CW Reed October 11, 2022

This is a great product..... however, only 3 Stars because I expect to get what I pay for! I purchased the 6 lb. tub, so I expected to get 6 lbs of usable product. But when I opened the container I found a dried ring approximately an inch and a half wide and deep around the top of the tub. I paid for 6 lbs but only received 5 lbs of usable product. This not the first time either. I have purchased a total of three of the 6 lb. tubs and three 1 lb. sizes over the last two years and ALL of them have the same issue. So, if you need the amount you paid for you will need to order and pay more or purchase another brand.

A very bad day, product or packaging was defective

SPY3 January 15, 2023

I have used this product before - and I will use it again. However, this order arrived with the top 1/3 of the product already set. I had to pry the set material out with screwdrivers to get to the "good", unset material. I was in the middle of a project, tools and pumps around, so returning the order for replacement was not reasonable. Very annoying and frustrating. Many bad thoughts were had by me.

I can't really attest to how well this seals or how quickly it dries because I didn't really get to use it in full. You have to be a bodybuilder to get the darn stuff out of the tube. I am 5 ft tall and 61yo and most definitely not a bodybuilder. I tried to use it for two days, gave up, chalked it up to a lesson learned, and threw it away.
