Flex Seal Paste, Super Thick Rubber Spreadable Paste, White 9oz Cartridge Sealants

it works. cracjs don't come back

It does all it says it can do. I have had leaky skylights for over a year and have tried various ways to stop the leak. Need I say more? Flex Paste sealed them up. I am going to get two more tubs of it, just to even out the job, now that the first application has set.

We put it on top of our toy hauler which had leaked the previous year. It was a chore prepping it and our friend who lives in it did a fantastic job painting wherever there was a possibility of water seeping in. Two days after competition we had a big, long storm, and all is well! I was worried about my friend and my nice toy hauler, but all is well!

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.

The tub is actually small. On TV it looks large. The product works great and it sticks to just about anything. The tub arrives with a foil covering or should i say partially covering the paste. The product not covered will have solidified. I estimate that i lost 25% of the product because of this. Maybe someone should check when they are making the product that the foil needs to COMPLETELY cover the product

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.

When I got the jar the outside of the paste was already hardened. About 1" around the jar. I used the inside of the jar and it was ok. I am not good at stuff like this and then I saw the spray kind and that is what I should have ordered to begin with!

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.

It's a great product, BUT, unless flexseal finds a better a better way to package their product expect to lose 1/3 . The top one third of every tub has already solidified when you open it. In essence you're paying for 2/3 of whatever is marked on the tub. I've got a bunch of solid donuts from each tub if anybody wants them. THAT ALUMINUM FOIL ON TOP IS NOT DOING THE JOB.

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.
