Things You'll Need
Masking tape (optional)
If you regularly work on crafts or art projects that use canvas as a material, you may find yourself in need of a way to securely glue metal to canvas. While there is a wide variety of glues available on the market, not all of them are suited to attach a porous material such as canvas to a non-porous material such as metal. According to the creators of ThisToThat.com, a reference website dedicated to methods of gluing different materials together, the best glue to use to attach metal to canvas is a classic spray adhesive.
Spray the adhesive on the canvas in the area you want to attach your metal to. Protect the rest of your canvas with masking tape if the area is small.
Wait for one minute for the adhesive to become tacky.
Press the metal firmly onto the canvas to attach it. Leave to set for two to five minutes.
