What is DIY Waterproof Glue?

DIY waterproof glue is a type of adhesive that is specifically designed to provide a strong and durable bond, even when exposed to water.

This makes it perfect for a wide range of applications, including outdoor projects and repairs. One popular use for waterproof glue is in gluing EVA foam for costumes and cosplay props.

How to Make DIY Waterproof Glue

Step 1: Gather the Ingredients

To make your own DIY waterproof glue, you’ll need the following ingredients:

  • PVA glue: This serves as the base of your waterproof glue. Make sure to choose a high-quality, waterproof PVA glue for best results.
  • Borax powder: Borax acts as a crosslinking agent, strengthening the bond of the glue.
  • Water: Water is needed to dilute the glue and make it easier to work with.

Step 2: Mixing the Ingredients

Now that you have your ingredients ready, it’s time to start mixing:

  1. In a clean container, pour 1 part PVA glue.
  2. Add 1/4 part borax powder to the glue.
  3. Slowly add water, stirring continuously, until you achieve a smooth and slightly runny consistency.

Step 3: Testing the Glue

Before using the glue, it’s a good idea to test its effectiveness. Take a small piece of the material you wish to glue and apply a thin layer of the DIY waterproof glue. Allow it to dry for the recommended time, and then expose it to water or moisture. If the bond remains strong and intact, you’re good to go!
