JB "Waterweld" - advice please.

Has anyone one here used the above product (it's from the same stable as "Weld" and "Marine Weld").

I need to seal multiple leaks in a rusty (once) galvanised water gutter. The surface is rusty and wet - this stuff looks like it might work. Any thoughts if you have used it or any other recommendations gratefully considered.

A new gutter will cost me €1000 so I'm hoping for a cheap fix

I used this stuff on the garage. http://www.lindab.co.uk/dokumenter/R...uctions(1).pdf Looks superb, easy to fix, not much more expensive than plastic sh*te.

Sounds very nice. Unfortunately mine is more of an industrial sized item - it's about 8" square section and about 80' long so replacement is to be avoided. I wasn't joking about the €1000, that was just to supply the new one, never mind a contractor to fit it

Thanks Tim, I wonder are we thinking about the same stuff - the blurb says that it is a "putty"

Willk,

It is a kneadable 2 part putty that is a bulker/filler and a hardner. It forms a plasticene type consitency paste that can be moulded for a while then it hardens off fully. I've never used it on a wet substrate, rust may need the loose stuff removing or it could blind the adhesive nature of it. It sticks ok but it is not as as good say as a mastic. It will perform best if it can be moulded say on both sides of a hole (like a rivet) or can be forced into something where it cannot come out after hardening (an undercut)

um, no, the inner side of the gutter is built into the top of the wall, I only have access to this inner side from INSIDE the gutter. And it's wet

sounds like a right pain in the posterior

Ah, rite. Ally patch, pop rivets and Sikaflex then.

wot he said works well but would as advised to remove any rust flakes for better bonding.

Tried this stuff - have to say it's something of a miracle and you'd wonder would it have a use in the emergency box? (they make a Marine Weld too)

A word of WARNING!

www.jbweldadhesives.co.uk are to be avoided. Only two items in a three item order arrived, no paperwork in the package. Two emails and two weeks later, still no comms. A Paypal case got the owner's (Paul Bradbury) attention and his lame excuse was that their email wasn't working and they were out of stock (remember no paperwork). WTF?
To be fair, the price of the missing/out of stock item was refunded.
