How to Repair Plastic Using Baking Soda
- 1). Squirt a couple of drops of quick-setting glue--cyanoacrylate-- onto the crack, hole or dented surface of your plastic.
- 2). Sprinkle a small amount of baking soda (enough to absorb the liquid) immediately onto the quick-setting glue. This will create a bonding material that fills the surface area.
- 3). Repeat the method if the split, hole or dent is large.
- 4). Sand the area with a medium-grit sandpaper after it dries, if necessary. This helps to create a smooth level surface.
