How to Glue Plexiglas to Steel

Adhere plexiglas to steel with the proper glue.

Steel and plexiglas are two heavy, durable surfaces that require more than a simple white crafting glue to adhere together. An instance may arise where you need to adhere the two surfaces, perhaps when a piece of furniture has a plexiglas shelf that comes loose from its steel base. You need to find a way to glue the two surfaces together so that the bond will last.

Things You'll Need

• Dish soap
• Paper towels
• Steel wool
• Clear-drying industrial-strength glue
• Clamp or heavy book

Instructions

1. Moisten a paper towel, add a drop of dish detergent, and wipe over both surfaces where you plan to apply the glue. Rub a piece of fine-grain steel wool over the steel surface if any heavy residue is present. This creates a clean, residue-free surface that will work best for glue adhesion.

2. Apply a thin layer of glue to each surface. Since these are two strong materials, it is important to apply the glue to both sides.

3. Let sit for 15 seconds to allow the glue to begin the drying process.

4. Push the steel and plexiglas together, and hold firmly into place for 5 minutes. When possible, lay the items on the side instead of leaving them standing upright.

5. Place a clamp or heavy object such as a book onto one of the surfaces to hold the objects in place.

6. Let sit overnight to allow enough time for the glue to fully dry and adhere.

Tips & Warnings

• Read the product label to make sure the glue you plan to use is designed for use on both plexiglas and metal surfaces; each glue typically has a list of suitable surfaces uses on the package. Also choose a glue that dries clear, as you do not want the glue to be noticeable through the plexiglas surface.
