Adhesive Recommendation

[Aven]

I have used Weldwood, Masters and Barge.  They all worked well.  Success is in the surface prep and the application.  Its better to use two thin layers of contact cement than one thick.

Another vote for Aquilium 315. Same reasons as the others, no fumes, and you don't have to worry about the wife or blowing up the house. Seems to hold as well as Weldwood.

I am another convert to the Renia Aquilium 315. I tried it about 1 1/2 years ago for the first time and now I wouldn't consider anything else. I do a lot of wet forming and that was my major concern when I started, would a water based adhesive hold up. It does and I haven't had any issues.

A couple of real pluses about using it are no more gripes from the wife about the smell of other contact cements and a very little bit of the product goes a long way.

I've used Fastbond 30NF by 3M. Another water based adhesive, but with a long work time (up to 4 hours).
I find it very useful, especially when glueing large areas or multiple items together.
