Foaming Tools!

摘要

The solution is based on filling the gap behind the insert with a medium - in this case I've used expanding foam, but plaster, silicone, or other media could be used to good effect, albeit at the expense of weight, and curing time. The insert is placed upside down (so the back of the insert is facing up) and a thin layer of spray foam is prayed in the back of the insert - paying particular attention to try and work the foam into the corners and crevasses (photo 2). A disposable sheet of paper or thin card is placed over the insert, and weighted with a large flat object - Here I have used a damaged suspension file for the disposable card, and a socket set to weight it all down (photo 3).
