How to Use CosBond with XPS FOAMCosBond Attach & Build is the best way to attach XPS Foam. Adhering XPS Foam together has always been a problem — you can’t use hot glue, contact cement, or superglue as they will melt the material. Wood glue is a viable alternative but it can take up to 24 hours to cure.
To attach XPS Foam using CosBond, start by cutting a piece of CosBond Attach & Build to the shape of the desired contact area. Remove one liner and attach the CosBond to the first piece — then remove the second liner and press the two pieces together firmly. This gives you an instant, powerful hold with no dry time and no fumes.
