Flex Seal in a can...

[KFC911]

I was thinking about spraying a screen door and rafting down the Nolichucky... or just stopping a minor leak around a skylight. Since Billy Mays died .... I don't trust TV pitchmen either .

Anyone used it... the stuff in the can that you spray on. Any other options or suggestions? Thanks!

Those chuckleheads at Mythbusters made a dingy out of duct tape. Don't know how wooly the Nolichucky is, but you could try!

Back when I worked in a photo lab, processing film we had two film processors that the chemical tanks were made of a grey plastic that felt much like teflon. No glue would stick to it at all. PCV cement was as useless as Elmers glue on it, and would just peel off. We had a slow seep from one very minor crack near the top to the fluid level. We tried everything we could find. Finally the boss came in with a can of flexseal. It just made a mess on that plastic.

We ended up having to hire a plastic welder to come fix the slow leak, and a bigger leak cause by an idiot employee hammering on the side of the tank trying to get a threaded fitting off.

It may well work for your skylight. No real pressure to hold back, just a slow leak. Just mask off the parts you don't want covered in the stuff.

I would think that you'd want to spray from the outside, not the inside. If you spray from the inside, I think you'll just collect the water and eventually send it somewhere else both of which sound bad.

I tried this stuff last week in a failed attempt to coat some tiki torch canisters that were leaking. The citronella oil dissolved the flex seal stuff at the leak points. Nothing on the can warning was not to use on or how to clean up. One of ten ski torches failed immediately (to had some rust through holes). The others with slow leaks at the seams are holding up but I think it is only a matter of time before they shoot craps>

This stuff sprays on super thin. You have to spray multiple coats to get any kind of buildup.

try HENRYS roof patch.
there are different types of it but dont know the difference.

I've never used it to stop a leak or seal anything, but I did use a couple coats on a pedal board I made out of a 2x4. I'm happy with the texture it provides as opposed to just spray painting it black.

^. That's cool! Nice rig. I assume the Altoids can is for the wireless?

Just picks! Only picks! You will not find anything else in there other than picks!

It really is just picks in mine, but some have been know to put other stuff in there. Stuff that they may use in between sets.

3 years ago when I rebuilt my wheelhorse mower deck, I sprayed the entire bottom. It is still doing a great job and nothing sticks to it.

Did you spray the Flex Seal on raw metal deck ? Or over primer/paint ? I am very surprised it can stand up to that harsh environment . Did you use clear or white or black ?

While we use it in new construction at underground foundation penetrations, I would not use it to fix a skylight. It's the flashing or the skylight itself.

Pitched shingle roof?

That stuff is good. Had a leak in the garage roof (nail hole) and it has kept it dry for 6 years now (sprayed outside and inside). Same with another leak around one of those venting pipes in the roof, cured as well.. One of those rare times TV-informercial-crap works ! Within reason of course, it won;t fix a structural issue - and other brands work too...

Tried it on a fridge waterflow sensor for icemaker and door water thing. No dice and $18 wasted.

The part is a plastic box like thing that water flows through. It has electrical connections and somehow checks flow and possibly pressure. Part has leaks that appear to be from plastic cracking. Part is only about $40 but has been on backorder for a few months.

We currently have to buy ice at the 7-11 and get water from the tap.

I primed it first. I used white Flex Seal. I am pretty surprised myself.

This is just a bandaid... gonna replace the pitched shingle roof soon. Sloped skylight now has a slight leak at the top that runs down the glass.... very minor, and it just started. Flex seal would be sprayed on the outside... until a "real fix". I need to get up there and take a look... could be the flashing or the skylight itself.

I hate ladders and climbing on my roof.... because I am NOT "roof girl" .

Thanks all!
