Boys and girls,

Desirous of glueing one piece of teak to another - a mounting pad under a cockpit table.

Any recommendations for prep and adhesive?

There will also be a few wood screws, but don't want to trust them entirely. No through fixings - reluctant to spoil the top surface.

Thanks in advance.

Cascamite is good as it is an epoxy. You could also use an epoxy resin like West System and colloidal silica to thicken it (West 406).
The most important thing is to d-wax the teak by wiping with a rag soaked in acetone or alcohol. Done right and you won't need the screws.
 
I have glued lots of iroko which is also an oily wood like teak and i only use polyurethane wood glue like Balcotan.

If the joint is prepared with the glue line a close fit joints I have tested joints where the wood has broken with the glue joint remained intact.

As said cascamite id not and epoxy and is not suitable for long tern immersion in water.

My plywood dingy I built 10 years ago only has screws where the bottom panel is connected to the stem all other joints are polyurethane only.
 
Being it's in the cockpit it could end up with standing water on the surface from any rain. You also get a lot more rain than we do

My own cockpit table very obtain gets standing from rain when erected and that is under a canvas cover.
 
Hi Ken.
Have a look at these peeps John and Ian really know what they are talking about.
Balcaton seems to be no longer available they have a new product just as good if not better "Collano adhesives are known by the name SEMPAROC".

Of course if you do use screws you can peg plug the holes.
I hope this helps David.

Ken it sounds very similar to mine and I don't use mine when sailing but it tends to get left up when in dock and it rains at night. Might be just me being to lazy to take it down when finished using it.
 
Evostick polyurethane glue, screwfix, B&Q etc. easy to use, great sticking capability and in and easy to use tube. Used it on scarf joints on my teak toerail with no problems at all.

I've used epoxy thickened with micro fibres and a few brown (I think they're phenolic resin) microballoons (to make it look a bit browner), to glue scarf joints in Avocet's rubbing strake. A trick someone showed me was to leave the ends of the teak to be joined in a tray of acetone for 10 minutes or so, prior to sticking them together. I was quite surprised at how much oily residue came out. Being bent round the boat they're under constant "peel (as bad as it gets for an adhesive joint) and three of them are fine. One popped when some git (I never found out who!) bashed it in a marina, but re-glued OK. The other tip is not to clamp the joint too tight so as not to squeeze too much of the glue out.
