Sticking memory foam.

[Grebo]

Any tip's ?

I just tried sticking two pieces with Helmicar 17020 spray glue & it looks like it has melted   :(
together leaving a thick lumpy join.
I have a few memory foam bed toppers to make up to 'boat bed shapes'

We use a product called Cami 303 to glue foam together.  We haven't used a lot of memory foam, but we used the same stuff to glue that and there was no melting or "lumpiness" to the join site. 

I found the memory foam a tough customer to handle because it tends to stretch out of shape when you're positioning  it.  I always ask for help when positioning it over the base piece.  And I frequently make little registration marks so I know I'm "in the ball park" as it's being lowered and the bond is made. 

I don't know much about memory foam but I wonder if the melting you've experienced is due to a different chemical composition in the foam? maybe European standards are different than those in the States?

Probably are Bobbin, the glue I use is fine with 'normal' foam. May be I got to much on it, I will try a lighter spraying.  ;)

Oh, BTW I am not fixing it down, but making up the shape. One boat has 185cm one end & 73cm at the other  ::)
( 2 metres long) The largest piece I can get is 160 cm x 200cm

Interestingly I have a temporary glue 505 & a craft glue 404 ( permanent repositionable) That might be worth a try, thanks for that.

That's pretty small sheets.  Don't you have access to memory foam bed toppers that are large enough?  Like these?

 :o NO.  :'(
But I will be buying them on-line. So may be I need to shop about more.  ::)

Looks like I was too heavy handed with the spray glue #2 ( same glue) is looking good.  :-[
