Styrofoam glue is a special glue used for gluing styrofoam. Gluing styrofoam can be necessary for at home craft projects, models, or other uses involving styrofoam and styrofoam adhesive. There are many different brands of styrofoam glue, which is good for you since your reason for needing to glue styrofoam might be different than someone else's. You may have to glue styrofoam by using a hot glue gun, while the 3M styrofoam glue spray might work for someone else's project.
Most of the time you will never use a hot glue gun directly on styrofoam, although there are the rare exceptions. Most styrofoam adhesive needs to be used either by spray or by actually gluing the styrofoam by hand. Most conventional styrofoam glue, therefore, will be in normal bottles and/or tubes, and tend to be smaller because most people don't have a consistent need for this type of specialized adhesive.
If you're looking to glue styrofoam, make sure ahead of time that you know exactly what type of specific styrofoam adhesive you need, that you have enough to get the project done, and that you know some of the basic information about your project, like how long to wait or how long to let the items dry. There are a lot of little things that can go wrong, and thinking the project all the way through from step A to step Z can be a good way of helping to dodge these problems before they ever take place.
Some of the more popular brands of styrofoam glue include: 3M, Henkel, and UHU. These aren't the only companies that make this product, however, and a little bit of research can go a long way in figuring out which one works best for you. Styrofoam glue is the best way to glue styrofoam together, and it is made especially for that purpose. Finding the right glue for styrofoam isn't that difficult, and once you have the right one, your styrofoam gluing project should go off without any hitch at all.
All it takes is some good know how, common sense, and a good vial of styrofoam glue.
