Why Do You Need a Waterproof Glue?
There are a number of reasons why you might need waterproof glue. Maybe you’re working on a project that will be exposed to the elements, or maybe you just want to make sure your work is extra durable. If you find yourself in need of a waterproof glue, there are a few factors to keep in mind while making your selection.
There are different formulations for different materials, so it’s important to choose one that’s compatible with whatever you’re working with. For example, if you’re gluing together two pieces of wood, you’ll want to use a wood-specific glue.
Once you’ve chosen the right kind of glue, the next step is to make sure you’re using it correctly. Waterproof glues require a little bit more care than regular glues, so it’s important to follow the instructions on the label carefully.
With a little bit of care and attention, you can easily find the right waterproof glue for your needs. Just make sure to do your research and follow the instructions carefully, and you’ll be able to create something that will withstand anything life throws at it. 
How to Make a Waterproof Glue: Easy Recipes
Recipe 1: Traditional Paper-Paste
Instructions: Start by mixing flour and water in a ratio of three to one. Add salt to the mixture and stir until it is fully dissolved. Heat the mixture over low heat, stirring constantly, until it thickens and forms a paste. Once the paste has cooled, apply it to your paper project. 
Recipe 2: Milk-based White Glue
This recipe is best for bonding porous materials like paper and cardboard.
Instructions: Combine the milk and flour in a bowl, then slowly add water until you have a smooth paste. Apply the glue to your project, then allow it to dry completely before putting the item into use. 
Recipe 3: Vegan-Mucilage Adhesive
This recipe uses flaxseed meal and water to create a sticky, waterproof adhesive.
To make this recipe, you will need:
- ¼ cup flaxseed meal
- ¾ cup boiling water
- A small bowl
- A spoon
Instructions: In the small bowl, mix together the flaxseed meal and boiling water until it forms a gel. If the mixture is too thick, add more water a tablespoon at a time until it reaches the desired consistency. Apply the mucilage to your project as you would any other glue and allow it to dry completely before using. Store any leftover adhesive in an airtight container. This recipe is great for those who are looking for a non-toxic, eco-friendly option.
Recipe 4: Basic Cornstarch Glue
- White vinegar (optional)
Instructions: Start by mixing together equal parts cornstarch and water in a bowl. If you’re using white vinegar, add a splash of it now. Stir the mixture until it’s smooth, then transfer it to a small saucepan. Cook the glue over low heat, stirring frequently, until it thickens and becomes clear. Once it’s reached this point, remove the pan from the heat and let the glue cool completely before using it. Store your homemade glue in an airtight container for future use. And that’s all there is to it! 
Recipe 5: Pine Pitch Glue
This recipe is a little more involved than the others, but it’s worth it for the strength of the glue.
- A double boiler or two saucepans that fit snugly together
- Pine pitch (you can usually find this at a craft store)
- Coconut oil
- An old toothbrush
To make the glue, start by melting the pine pitch in the double boiler. Once it’s melted, add equal parts beeswax and coconut oil to the mixture and stir until they’re completely combined. Remove from heat and let cool slightly before using an old toothbrush to apply to your project. This glue will dry hard and waterproof, so it’s great for outdoor projects.
Recipe 6: Sourdough Glue
- Sourdough starter (active, from the fridge is fine)
Instructions: Mix together equal parts sourdough starter, water, and flour. Add a pinch of salt and mix well. Allow the mixture to sit for at least 30 minutes before using. This glue can be stored in the fridge for up to a week. To use, simply brush on a thin layer of glue to both surfaces that you wish to adhere. Press the surfaces together and allow the glue to dry completely before subjecting it to any stress or moisture. This glue is not recommended for outdoor use. 
Recipe 7: Gelatin Glue With Vinegar
In a small saucepan, mix together:
- One tablespoon of granulated gelatin
- One cup of cold water
- Let the mixture sit for about five minutes to let the gelatin bloom.
- Bloom is when the granules of gelatin swell and absorb water to form a gel.
- After the bloom period, heat the pan on low heat until the gelatin has dissolved completely.
Once it has dissolved, add in:
- One tablespoon of white vinegar
- Stir until mixed and then remove from heat. The glue will thicken as it cools. Once it’s thickened, you can use it like any other glue!
Keep in mind, this glue will not be as strong as some of the other recipes on this list.
Hot water will dissolve the granules faster and result in a stronger bond.
Things to Avoid When Making a Waterproof Glue
- Do not use an already wet surface.
- Avoid using too much water.
- Do not let the glue dry out completely.
- Do not apply too much pressure.

If not, you may need to adjust the ratio of ingredients slightly.
What glue is totally waterproof?
There are a few adhesives that perform well in wet conditions, but no glue is completely waterproof. The best way to make sure your project can withstand moisture is to use a sealant over the top of the glued area. This will provide an extra layer of protection against water damage. Here are a few tips for using glue in wet conditions:
- Choose an adhesive that is designed for use in wet conditions, such as Gorilla Glue or E6000.
- Apply the glue to one surface and allow it to dry before joining the two pieces together.
- Use clamps or weights to keep the surfaces together while the adhesive dries.
- Apply a sealant over the top of the glued area for extra protection against moisture.
- Store your project in a cool, dry place until the glue is completely dry.
