I need sticky stuff

[Pocster]

Got my recycled plasticy stuff decking and trim . Tried ct1 , gripfill etc . The trim sticks for a bit - but after rain , sun , hot , cold always eventually comes loose . There will be a lot of trim ( to hide all the shit cuts ) .

What magic sticky stuff bonds this plastic stuff so nothing on earth can seperate it ?

No good doing a mechanical fixing as screw through plastic trim into plastic decking just wears the fixing and then it pops off also …

I glued a bit of ply to a recycled plastic bench over a year ago.

If I can be bothered, I shall pop to the woods tonight and have a look.

Generally there are better things to look at in the woods at dusk, but for you, I shall resist my urges and just stick to the plan.

always thought screws were the way, maybe a screw with course threads...

You could try Mitre Mate.

Been to the woods, seems the new owners of the cafe have changed the benches.

But no matter, here is a picture of some ply stuck to a slab that has been out in all weather for over a year.

I wiggled it and it did not come off.

I am sure a tube of Lumberjack will sort you out.

Not heard of that - will give it a try . There I was believing that ct1 was the be all and end all of bonding .

You shouldn’t be in the woods on an evening . Cornish people do strange things in those situations . It’s not normal

I play around with recycled plastics quite a bit and I've yet to find a glue that sticks to it. Use lost head screw for best finish.

 

Depending on the decking type a bit of WD40 on the screw before driving it in helps buy displacing the plastic instead of cutting it away. The head becomes more "lost" in the plastic. 

 

Make sure to use stainless screws. Nothings worse than a fancy, permanent, rot proof, ever lasting decking structure.........with some rusty ass screws stuck in it. 

 

Btw, What decking did you go for?

I used

It’s really good stuff but … the ‘special ‘ brackets and screws bump the cost a lot . I choose this because of the aluminium frame I.e do once and it should last forever

No good for polypropylene, polypropylene and polytetrafluoroethylene, so that is most of the recycled plastics out then.

It’s recommended by the decking supplier so I *assume* their recycled product isn’t one of those you list .
