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
