Glueing polyethylene to wood

[nickelodeus]

Hey Peeps,

 

I need to stick a couple of 3mm polyethylene strips to the inside of my hatch - which is lined with ply. I've been using a non-solvent gap filling adhesive for other bits, but I know that you can't use it on polyethylene or polyurethane.

 

I've had a look round on the web and I know that there are adhesives recommended for this purpose (3m scotch spay stuff) - but its expensive and I can only see myself using it once (ie just for this job).

 

Is there anything more common and cheaper that would be suitable for doing this job - perhaps wood glue or pva? I'd like to make a decent job of it so it doesn;t have to be done again.

 

Thanks!

Nick

Polyethylene, like polypropylene is quite a difficult substance to join. Often it will be welded because not many of the solvent based adheseives that will bond say PVC will work. Suggest you try a hot melt glue gun, may hold for some time but will probably fail long term.

Screw it on with brass or stainless screws, bed it onto something like Sikaflex. I don't think you'll have much luck glueing it.

Hi Guys,

 

Thanks for your replies. Ok let's say that I abandon the adhesive route here and screw the plastic in place instead. I want to maintain a percectly flat, flush surface so I would probably have to counter sink? - only thing is that my plastic runners are only 3mm thick. Could I still do this?

 

Perhaps there's a far simpler way of doing this that I'm missing here....let me know if you come up with anything!

 

Thanks again

Not sure if its cosmetic trim or a load bearing runner but if the former, double sided sellotape, carpet tape or foam strip might work - the double sided carpet tape is mega sticky and strong.

 

On the subject of adhesives I am quite a fan of Evostick impact adhesive. once set it appears to be stable in sunlight / waterproof and I have used outside to finish seal cable connections where it has lasted years. And it smells great !!

Yes, countersinking in 3mm no problem. Use a proper countersink bit the right size for your screws, don't try with a drill bit as the angle is wrong, plus you'll almost certainly end up with a bigger hole right through the plastic.

What about "no nails" or silicon sealer?

 

Sounds like the stuff that kitchens are lined with & they use some sort of mastic to slick it up.

Polyethylene is notoriously difficult stuff to stick, normal adhesives don't stand a chance.

Were they polyethylene?

I used Grip Fill when I glued strips on our hatch where it runs on the brass runners. Its under compression all the time with a shear force when you slide the hatch. I took the hatches off last time out to have a bit of welding done on them and all 4 strips were still sound.
