Memory foam is used for a variety of purposes, from bed mattresses to upholstery. It is especially used in the home due to its conforming features that provide added comfort to the body. If your memory foam happens to become ripped or torn or you are simply constructing something of memory foam, you need to glue the memory foam together. Memory foam cannot be glued with just any type of glue, however; you need a spray foam adhesive.
Spread newspaper atop the area in which you plan to work, and arrange the memory foam pieces so they are evenly lined up in the manner in which you wish to glue them.
Spray the ends of the pieces of memory foam that you wish to glue together. Mist them lightly with the spray foam adhesive and allow them to sit for approximately 15 seconds until the spray adhesive becomes tacky and sticky.
Press the pieces firmly and evenly together.
If you are unhappy with the placement of your memory foam pieces, pull them apart immediately after positioning them and reposition them.
Spray adhesive dries quickly, so work quickly when working with it.
