Although wrought iron is very strong, it is made from porous cast metal that will break under pressure. In the event you have wrought iron that does break, you can repair it with epoxy weld. This is an alternative to stripping the wrought iron and welding it with a pop welder. You can repair your wrought iron with a few dollars in supplies and a little bit of your time.
Sand the broken surfaces to remove approximately 1/4 inch of paint from both ends of the break. Use a piece of 600-grit sandpaper for this.
Remove grease and dirt from the surface of the wrought iron with a clean rag dipped in white spirit.
Mix the epoxy weld or epoxy resin per the instructions on the packaging. High-quality epoxy welds and resins require a base and a catalyst. Mix the two together to achieve a thick, claylike material.
Apply the epoxy to the surface of the wrought iron and put the two pieces together.
Secure the two pieces together with a clamp.
Apply a bead of epoxy around the break to add additional strength, and allow at least 24 hours drying time.
