Need to make a repair in metal? Here are some popular adhesives that can make a strong bond with metal:
- Steel epoxy: A two-part compound sold in tubes, steel epoxy is quite similar to regular epoxy. It forms a very strong, durable, heat-and water-resistant bond and is recommended for patching gutters and gas tanks, sealing pipes, and filling rust holes. Drying time is about 12 hours; curing time is one to two days.
- Steel putty: This metal putty consists of two putty-consistency parts that are kneaded together before use. It forms a strong, water-resistant bond and is recommended for patching and sealing pipes that aren't under pressure. It can also be used for ceramic and masonry. Curing time is about 30 minutes; when dry, it can be sanded or painted.
- Plastic metal cement: Plastic metal is one-part adhesive and filler. It is moisture resistant but cannot withstand temperature extremes. This type of adhesive is recommended for use on metal, glass, concrete, and wood, where strength is not required. Curing time is about four hours; when dry, plastic metal cement can be sanded or painted.
