Depends on the glue. If white glue or another PVA, then scrub it with warm water and shop vac it up. Repeat 2-3 times.
-If other types of glue then you need to be more specific. -Name your glue-
High density polyethylene foam. Use heat. Non foam plastic use super glue.
You should use a craft glue or a specialized foam glue for foam sheets. Regular glue may not adhere well to foam.
No, there is no carpet glue in cigarettes.
Try some good old fashioned finger nail polish remover. It works on super glue.
You can find the type of glue you need at the upholstery shop. They will be able to advise you on how to make the repair you need. It will probably be a good idea to use both a foam glue, and some upholstery tape to hold it together.
You could use duct tape to put it together, or hot glue it.
The best glue for polystyrene foam is a solvent-based adhesive specifically designed for bonding foam materials.
Yes, I believe so. You can use wood glue on foam.
NO super glue is not elmers
We need details on what the mats are for. Under carpet, a table, an upholstery project, etc. etc. since sometimes there is no need. If it is thin and must be glued and a smaller project-there are spray upholstery adhesives in an aerosol can at many better auto parts stores-that will hold it.
That depends what kind of glue it is. -I would try Goof -Off for removing unknown glue from a carpet.
of course you can !ANS 2 - I don't know what 'fun foam' is - but I DO know that hot glue melts many foam surfaces.
