Which glue can I use with foam for my modelling?

When working with foam, there are several glue options to consider:

• Hot glue guns: Hot glue is one of the most popular choices for sticking foam pieces together. It dries rapidly, forms a sturdy bond, and is straightforward to use. Low-temp hot glue guns are recommended as they are less likely to damage or melt the foam.

• Cyanoacrylate (Super Glue/CA Glue): Super glues like cyanoacrylate work well for bonding foam, especially dense foam types. The bond forms very quickly. Take care as some foams can react with the glue and cause cracking or discolouration.

• Foam-safe adhesives: There are specialised foam adhesives made specifically for bonding foam materials safely without damaging or dissolving them.

• Spray adhesives: Spray mount adhesives or repositionable adhesive sprays can be used to join foam sheets or pieces temporarily or permanently, depending on the product.

• PVA: Regular PVA glues can work for porous foam types but may not create the strongest bonds compared to other options.

The key is using adhesives labelled as "foam safe" or low-temp hot glues to avoid damaging, melting or dissolving the foam material. Test on scrap pieces first, and ensure proper ventilation when working with adhesives.
