Thread: Waterproof Contact Adhesive

"Bear Brand", contact adhesive was used for many years to glue laminex etc, to kitchen benches and all sorts of other things as well.
I think it is a Selleys brand.
I would have to look in my other workshop to tell you for sure.
I don't know what degree of "water proof", you are looking for, but if you want a truly water proof glue, you need to use epoxy.
It is not contact, but if you have the time it is very permanent.

Thanks Paul

I have spoken with Selleys but none of their contact adhesives are w/proof, guess such a beast does not exist yet/still.

What do you need the glue for. ??
That might help us all answer your question.

Paul I have often fancied doing a couple of 'cold molded' jobs since way back when reading the Gougeon Bros WEST Systems book but could never stomach the thought of using cleats and fastenings to hold laminates steady then filling the holes later (what a terrible thing to do to wood). Vacuum set ups are not practical for the specific use in mind either.
I have only made ply 'cold' in a mold but never over a male frame for one off jobs like a boat, kayak or surfboard for that reason.

Using epoxies and the like is just so time consuming and messy. Say for instance making an HWS (hollow wooden sboard) in cold mold 2 or 3 ply wait 24 hours min between each layer whoah. It would take weeks instead of a day or 2 max air dry to touch press to seal then sand in the same day....yes my very own pipedream. lol

Every one should have a dream Steve.

Steve, I know nothing about surfboards, but watched a friend build a cold-moulded boat. All that (expensive!) wood got covered in fibreglass/resin at the end, so no-one ever gets to see the very small holes left by the staples that held the strips in place while the epoxy cured. Isn't a surfboard likewise encased in resin after it's formed, & does that not form a waterproof barrier over the wood? But apart from water-resistance issues, contact adhesives remain plastic to some extent & so are not really suitable where there is constant tension on the joins, as would be the case in most 'cold-moulding' applications.

Cheers,

Yes right you are Ian, most certainly are glassed over. And I am almost ashamed to admit that I had never given a thought to .... "regarding the properties of any finished contact adhesive" and for sure the behaviour of any finished 'glue' always needs to be considered. I guess i like to see things hidden and secret where possible lol.

I quite late but in case someone is still wanting an answer, the product is Aquaseal.
