Pool noodles are much more than just a fun floatation device for the pool! These colorful, versatile foam tubes can be transformed into all sorts of creative projects, from DIY decorations and craft items to protective padding and learning tools. But what do you do when one noodle isn’t long enough, or you need to connect several to build something bigger? That’s where knowing how to glue pool noodles together comes in handy!
While pool noodles are soft and flexible, finding the right adhesive can be tricky. Some glues might not stick well, others could melt the foam, and some might not hold up to water or stress. Don’t worry, we’re here to guide you through the best methods and materials to ensure your pool noodle creations stay firmly connected.

Choosing the Best Glue for Pool Noodles
The secret to a successful pool noodle project often lies in selecting the perfect adhesive. Here’s a look at common glues and how they perform with pool noodles:
-
Construction Adhesive (e.g., Liquid Nails, Gorilla Glue Construction Adhesive)
The Top Pick: For a strong, durable, and waterproof bond, construction adhesives are often your best bet. These powerful glues are designed to adhere to a variety of materials, including foam, and can withstand outdoor conditions. They offer some flexibility once cured, which is great for the noodle’s natural movement.
- Pros: Excellent strength, durable, waterproof, flexible bond.
- Cons: Slower drying/curing time (can take 24-72 hours), requires good ventilation, can be messy.
-
E6000 Craft Adhesive
Another fantastic option, E6000 is a favorite among crafters for its versatility and strength. It forms a flexible, waterproof bond that holds up well, making it suitable for projects that might get wet or need to flex.
- Pros: Strong, flexible, waterproof, good for crafts.
- Cons: Slower drying time, strong fumes (use in a well-ventilated area).
-
Silicone Sealant/Adhesive
While primarily used for sealing, clear silicone sealants can also work as an adhesive for pool noodles, especially if flexibility and water resistance are key. The bond might not be as strong as construction adhesive, but it’s excellent for areas that need to be watertight.
- Pros: Very flexible, waterproof, good for sealing gaps.
- Cons: Weaker bond strength compared to other options, slow curing, can be messy.
-
Hot Glue
Hot glue is super fast and convenient for quick fixes or temporary projects. However, it has some significant downsides for pool noodles. The high temperature can melt the foam if not applied carefully, and the bond isn’t waterproof or very strong, especially under stress.
- Pros: Dries quickly, easy to use.
- Cons: Not waterproof, weak bond, can melt the foam if too hot, rigid bond.
-
Super Glue (Cyanoacrylate)
While super glue offers a very strong and fast bond, it dries rigidly and can make the foam brittle at the joint. It’s generally not recommended for pool noodles, which need flexibility, and its bond can easily break under stress.
- Pros: Dries very quickly, strong initial bond.
- Cons: Rigid and brittle, not flexible, fumes, can break easily.
-
PVC Cement
This adhesive is designed for PVC pipes and contains strong solvents that will dissolve and melt pool noodles rather than bond them. Avoid using PVC cement on foam noodles.
Factors to Consider When Choosing Your Glue
To pick the best glue for your project, think about these points:
- Project Type: Is it a temporary craft or a permanent outdoor fixture?
- Water Exposure: Will your project be in or near water? (Choose waterproof!)
- Flexibility Needs: Does the joint need to bend or remain rigid?
- Drying Time: How quickly do you need the bond to set?
- Safety: Always ensure good ventilation, especially with stronger adhesives.
Step-by-Step Guide to Gluing Pool Noodles Together
Once you’ve picked your adhesive, follow these steps for a strong, lasting bond:
-
Preparation is Key
- Clean and Dry: Make sure the surfaces you’re gluing are clean and completely dry. Any dirt, dust, or moisture can weaken the bond.
- Cut Evenly: For a seamless connection, cut the ends of your pool noodles as straight and even as possible. A sharp utility knife or serrated knife works best.
- Test Fit: Briefly hold the pieces together to ensure they align perfectly before applying glue.
- Roughen Surfaces (Optional but Recommended): Lightly sand the ends of the noodles with fine-grit sandpaper. This creates tiny abrasions that give the glue more surface area to grip, leading to a stronger bond.
-
Apply the Glue
- Apply a thin, even layer of your chosen adhesive to one of the noodle ends. Don’t overdo it; too much glue can weaken the bond and make a mess.
-
Join the Pieces
- Firmly press the two noodle ends together, ensuring they are perfectly aligned.
- Twist slightly as you press them together to help spread the glue evenly and create a better seal.
-
Secure and Cure
- If possible, use clamps, tape, or weights to hold the glued sections firmly in place while the adhesive cures. This consistent pressure is crucial for a strong bond.
- Follow the glue manufacturer’s instructions for drying and full curing times. This can range from a few hours to several days, but patience is vital for maximum strength.
-
Finishing Touches
- Once fully cured, carefully remove any excess glue that may have squeezed out. You can often trim it with a sharp knife or scrape it off once dry.
- For extra strength, especially on larger projects, consider adding internal dowels or external reinforcement.
Tips for a Super Strong Pool Noodle Bond
- Internal Dowel: For ultimate strength, especially in load-bearing projects, insert a wooden dowel or PVC pipe connector into the hollow core of both noodles before gluing. This provides a rigid core for the glue to adhere to and significantly reinforces the joint.
- External Reinforcement: Wrap the joint with strong, waterproof tape (like duct tape or electrical tape) after the glue has dried for added stability and protection.
- Use Enough Pressure: Don’t just press and release. Apply consistent, firm pressure during the initial setting phase of the glue.
- Ventilate: Work in a well-ventilated area, especially when using stronger adhesives with fumes.
FAQs About Gluing Pool Noodles
Got more questions about sticking pool noodles together? We’ve got answers!
-
Q: Can I use duct tape to join pool noodles?
A: Yes, you can for temporary or light-duty projects. Duct tape provides a quick and easy connection but isn’t as durable or waterproof as a strong adhesive, nor does it create a truly rigid bond. -
Q: Is Gorilla Glue suitable for pool noodles?
A: Yes, Gorilla Glue offers several products that work well. Their Gorilla Glue Construction Adhesive is highly recommended for a strong, flexible, and waterproof bond. Their original polyurethane Gorilla Glue also works but expands as it cures, which can be messy and requires clamping. -
Q: How can I join pool noodles without glue?
A: There are several glueless methods! You can use zip ties, string, strong tape, or even internal dowels (like wooden sticks or PVC pipe pieces) for a snug friction fit. For a permanent, waterproof bond, some people carefully melt the ends together with a heat gun, but this requires extreme caution and practice. -
Q: Can I melt pool noodles together instead of gluing?
A: Yes, with extreme care. Using a heat gun on a low setting, you can gently melt the ends of two noodles until they become tacky, then press them together. This creates a very strong, waterproof, and seamless bond. However, it’s easy to over-melt or burn the foam, so practice on scrap pieces first and always work in a well-ventilated area.
