Aluminium Boat

Any suggestions,how to glue marine plywood to the aluminium surfaces?
I dont want to screw it!

 

Go to 3M.com they have a 2 stided tape speacially designed for metals and after 24 hrs cure time the stuff is about as strong as welded!

 

I beleive in my readings of either the literature of West or System III, with the proper surface prep you can just glue the marine ply to the aluminum...

Check it out, worth a shot anyway...

 

5200 and good surface prep

 

gluing plywood to aluminum

Rough up the surfaces of the wood and the aluminum and use "sikaflex" marine sealant. This stuff holds like nobody's business. Only draw back is it is very messy so be careful and good luck.

 

For areas where you may need to remove lining use self adhesive Velcro tape from 3M
Simply stick the tape to the area you wish to cover with the second side glue side out and press in place,
Most brands have backing tape so you only need to expose enough to trail fit then remove the balance to attach more permanently

Sand, primer, "glue", vacum= the most durable way

 

Epoxying Aluminum

With chemical protective gloves on, cover aluminum with epoxy and then under the cover of the epoxy use 60 grit wet-dry sandpaper to remove the oxide layer on the aluminum.

At this point the aluminum surface cannot reoxidize because it is protected from atmospheric oxygen. Continue with the bonding process.

The 60 grit sandpaper not only removes the oxide layer but also roughs the surface enough to give the epoxy a good grip.

 

i've had luck with sanding the metal a bit and then using a marine quality caulking. you can get it in a tube or get it in a tub, i'd suggest you go with a tube. if you can only get the one in the tub i HIGLY urge you to wear gloves! once the stuff gets on your skin it has to wear off . hope i helped!
