Glue for pink foam


My next project is most likley going to be with the 1/4 inch pink fanfold. I also have most of a 2" 4x8 sheet in the garage to work with too. What is everybodys glue of choice. I have medium foam safe ca and some probond and a hot glue gun. If I have to I can work with those. The ca sometimes takes a while to set up and I dont like waiting forever with the probond. I read something last night about mixing it with white glue instead of water so I may have to give that a try. The hot glue works well in some places but other places its just not quite what I need.
Just looking for other options. Is there a contact cement or rubber cement in a can that wont eat the foam? Doesent help that im impatient when it comes to glue drying.

I use gorrilla glue, you have to wait for it to dry but it makes great joints and fills large gaps with good streangth.

Nick,

If you want the Probond( elmer's brand) to cure faster mix it 75/25(elmer's white glue) starts to harden in 20-35 mins then let it cure for 2-4 hrs. I also have done 50/50 take 15- 20min. It will look light grey in color when mixed.

glue


I've done quite a bit of work with Blucor and tried lotsa different types of glue.
The type that gives me the most satisfactory results is canopy glue, i.e., RC-56 or Pacer Formula 560. Yes, you have to wait for it to dry, but the end result is worth it. They are supposedly the same formulations, but I have worked mostly with Formula 560 which happens to be the most expensive of the two.
Just this past week a buddy of mine discovered a product at A.C. Moore called Super Tacky which comes in a 4 oz. bottle for $.79 and appears to have the same characteristics as Formula 560. He brought a couple of pieces of 3 mil Depron that he had glued together with the stuff and I couldn't pull them apart without destroying the foam.
3M C-77 is a contact cement that doesn't attack many foams and is pretty strong, but try it first on a test piece just to be sure.

I like Polyurethane glues. Gorilla or Probond.

Probond is a bit runnier then Gorilla.

Mixed with water 3 parts glue to 1 part water speeds the curing a lot.

Probond (polyurethane glue), Gorilla glue (basically the same) are great for foam. Be aware they expand a lot, especially if mixed with a drop of water or if high humidity is present. Tape the glued joint to prevent the glue to burst out too much.

A new polyurethane based glue that does not expand that much is the Sumo glue (I only saw it at Lowes). It also cures quicker, but it is a bit more expensive.

Many times I prefer epoxy because I do not have to worry about the expansion.

I use 3M Super 77 to laminate foam sheets. If too much is applied it will eat foam, so apply in quick passes. I use it on bluecor, pink foam, depron. Itís good to practice on some spare pieces first.

Hope it helps,

a hot glue gun set on medium. That's all I use for foam flyers.

Time for another motto!
UHU-por is a nice foamsafe contact cement. Apply thin to both surfaces, let it dry for a few mins and push tightly together. It remains a bit rubbery, but for foam that is not bad. UHU is made in germany, but i've heard it was wexported to the US too. United Hobbies has some glue too, and as a nice exotic cachet, the tilte 'Foam Safe Glue' is printed in chinese on the tube. Gws has similar glue with their kits, maybe that is for sale separately too.

UHU-por is the best, strong, yet slightly flexible joint.

Loctite has a new glue called Sumo which is a clear version of Gorilla Glue. It turns white when it foams instead of brown like Gorilla glue. Its my slow glue of choice on Depron.
