Hoping the great GZ minds can assist.

Just spoke to Ados CRC about the right adhesive to use to stick an aprox 15 cm strip of rubber latex to the bottom end of a 5cm thick pure rubber latex topper. He said they didn’t have anything that would work. Topper was cut down from a double bed size to king single, but was too short so needed the piece added. I thought it would be a simple matter but appears to be a lot more complex.

When I look at Bunnings etc their adhesives don’t show the back of the label instructions so you can't make an educated guess. The Warehouse are even worse with no relevant descriptions.

Non toxic would be important. I also thought of some sort of sticky cloth type tape to go over the seal to give it strength after adhesion, but not sure what would stick, thinking a sticky web like they use for Gib seals maybe.

Thanks.

Not sure whether you have searched.

More specifically, I found this YT video which may help.

Ados CRC should know but I'm surprised they couldn't help. I would have guessed that their F2 contact adhesive would have been spot on.

Sometimes I just sit and think. Other times I just sit.

Don’t forget it is a soft foam that can crumble, not a solid smooth surface as in the video. ADOS said that any join would eventually give way. I was hoping someone who makes masks or models may have an answer. Didn’t want to bother anyone at Weta.

I wondered how long it would take for something like this to come up!

Every site I have seen advises spray glue is the answer:

https://www.thefoamfactory.com/blog/index.php/how-to-glue-foam-helpful-diy-foam-tips

The above is just one such site, but most advise contacting a mattress company to see what they are using and whether they are willing to assist with supply.

In your thread title and your OP you mentioned latex four times - nothing about foam.

You don't know what a mattress topper is?

Of course - we have a mattress topper and it's some sort of thick quilting covered in soft fabric.

To make it clearer this is a photo of the cut side. It’s very heavy but soft and bouncy sponge like. It’s not light like foam sponge. Two people need to lift a big piece.

My plan was to bond the two smooth sides together that you can’t see in the photo, not the cut sides shown which also very easily tear. Then it has a zipped cover that goes over the whole thing. They are pretty expensive to buy so worth the bother.

Rang a old mate and used to make Latex matts suggests

If you are sticking the outside not cut parts use

Ados F2 Contact adhesive or a standard hot glue gun

Best of luck

I would also reinforce it with some sort of mechanical bond, e.g. stitching if you can get it through the foam, since as others have pointed out it's both a bit crumbly and will be subject to constant movement from people on it. I don't know if I'd trust any adhesive to hold up under those conditions.

@Eva888, if you're in Orkland I think I have a pot of F2 somewhere from which you could grab some, that stuff isn't the cheapest particularly if you only need a spoonful of it.

Just rereading this, you want to do a butt joint, so glue the pieces end-to-end rather than one on top of the other? For that I'd been even more nervous about any kind of glued joint holding it, that's the weakest possible joint type and then you've got spongy foam that isn't going to make good contact.

If it is a butt joint I'd perhaps glue or stitch straps to the larger bit and then glue/stitch the smaller bit into the straps. And run some stitches the around the join between the larger and shorter bit to stop any gap opening up.

Yeah, Frankentopper!
