Gluing marine ply to ali, what glue?
James - 29/5/06 at 02:08 PM

Not sure my dash is stiff enough. Thinking of gluing a sheet of marine ply to the back of it.

What sort of glue would you recomend? Is Impact Adhesive up to the job? The stuff in the red pots?

Thanks,
James

sikaflex would definatley do the job, bit pricey though..

PU or epoxy

Slight hijack, but are there different types of sikaflex? If so, which types are suitable for what?

I've used some 'serious stuff' by Evostick from B+Q. I think it may be a cheap PU adhesive. Bonds most materials apparently and pretty cheap.

Evo-Stik impact would be ideal. or just use spray adhesive, the one carpet fitters use. Put a thin film on both surfaces and let it go off then whack it together but make sure you get it in the right place as you won't get a second go if the surfaces are good.

Many years ago I my father did an emmergency storm damage repair on a carvan, he stuck a square of hardboard on to a door with evostick impact ---- wasn't half effective.

James, You still doing work for the car mob? Maybe you could get them to laminate a bit of hex cell and a layer of kevlar on the back, to form a nice sandwich. Little side job for the laminating lads.

Cheers,
Syd.

I have used just PU wood glue, and believe me, you wouldn't want to try and get it apart. Sticks like s**t to a blanket.

Sikeflex is a tradename. Very common so often gets used as the generic name for PU adhesive. There are several makes around. Wurth bond and seal is very good (very possibly sikaflex in a wurth tube). There are some cheaper brands which are ok for most applications. For applications that are structural or you dont want to risk a problem (ie bonding cycle wings) id go for the better more expensive named brands.

James id be tempted to use PU. At least it doesne get affected by dampness.

The Sikaflex sold in panel shops and yacht chandlers is high modulous PU and has a quick cure time which is what enables it to be used as an adhesive. Builders PU is normally low mod and slower curing time as well as being cheaper. Prolly cos it aint made by a Swiss company who like to keep their country clean by manufacturing in more needy countries

Thanks everyone.

I've got a cheap PU version so I'll give that a go I guess.

Cheers,

There's a Sikaflex builders' adhesive that I use - it's black, very sticky, and very good at holding stuff together... rather like classic PU sealant.

Can't remember its reference number just now, but it cost me around £5 for 2 tubes, in a paint supply shop (not a cheap place!).

Car builder solutions 7.50 a tube and i love the stuff, seals, sticks and bonds. I always have a tube hanging about.
