Waterproof Glue Recipe

When you’re gluing something together that’s going to go under water, you need a glue that doesn’t melt. This waterproof glue recipe is the one you need.

This homemade glue needs to be applied warm so it will form a bond. Even then, it’s not the strongest glue in the world and the bond may not last forever. But it does stand up to being in water.

It’s a good idea to make small batches of it so you can use it all up in one go, while it’s warm. For future applications, put the glue container in a bowl of hot water to warm it up again.

Apply it with a brush. It can take a few days to gel, but it’s good for lots of crafts.

A lot of waterproof homemade glues include milk, which of course spoils quickly. This one will actually keep for a while, but isn’t quite strong enough to hold together something like a broken china plate.
