Fixing poly nuc super

[Smudger55]

Hi, can I use copy dex glue to fix a cracked poly nuc super , I have used it before when bits have broken off , but not to fix a crack from top to bottom …..

No idea about copydex. Probably, yes.

Paynes do a bespoke one for polystyrene, but it's probably a lot more expensive!

I believe Copydex is a water based acrylic adhesive and as such will disolve when it gets wet again. You would be better with a polyurethane like gorilla glue.

Spot on ... Copydex won't work - it's not waterproof. Polyurethane glue is best and if it's a crack right through the poly I would dig out the first couple of millimetres of the crack and skim it with car body filler.

Gorilla glue is brilliant but expensive and if you are not using it regularly it goes off ... so buy the smallest you need to fix the problem as it does not keep well.

This is about the smallest you can buy,

UHU POR - special adhesive for hard foam like styrofoam, wood, plastics etc etc.....

I found polyurethane glue, both foaming and non-foaming, on Amazon for less than Gorilla Glue. I assume it's the same stuff. It comes with a proper closure for the spout, too.

I have a poly brood box that suffered painfully during the recent storms. I shall be giving the glue a go on that.

Ordinary Portland Cement (I think JBM must be engrossed in Countryfile)

No - SWMBO fed me a load of Jerusalem artichokes earlier, I decided to step outside for a breath of fresh air.
They didn't half kick in quickly and the canary just fainted.

I agree gorilla glue is brilliant but goes off too quickly in the tub. I use this which is much cheaper and lasts much longer.

That's a good price ....probably just as good as Gorilla for most jobs ... I like Gorilla but it drives me mad coughing up £13 and when you come to use again it a few weeks later it's set like rubber tyre ! I use Titebond 2 for my woodturning and woodworking which is excellent but it's not up to sticking poly hives back together.

Never used the Titebond 2 but do use the 3 and it works very well. I glue and put in at least one screw to brace the repair on the odd occasion I've been clumsy.

There seems to be a plethora of types of gorilla glue. I use the expanding foam version to fasten points into carbon fibre arrows. Roughen smooth surfaces, apply a thin coating of the glue and assemble. Wet the assembled piece and allow to cure while maintaining pressure to avoid the gap opening up.
It's quite a small bottle with a cap and I've had it for 6 months with no sign of the contents solidifying.

I have found that the Gorilla glue can go off in the dispenser BUT if it starts to go stiff a quick short blast in the microwave will let you use it for a lot longer. Just watch it doesn't spurt out when it gets hot though.

I find warming it in front of the blow heater I have in my workshop makes it much easier to use.

Do you use gorilla glue on poly?

I use the soudal 45p, as above, on poly.

I used gorilla glue to repair my poly hive. Worked a treat.

Helps to store a partially used (sealed) bottle upside down - in a jar, perhaps. Liquid glue sits up against the cap, preventing moist air in the bottle setting glue at that end.
