how to seal stickers on hydro flask


Sealing stickers on your hydro flask not only adds a personal touch but also ensures their longevity. By properly adhering the stickers and protecting them from moisture and sunlight, you can enjoy a beautifully customized hydro flask for a long time. In this article, we will guide you through the step-by-step process of sealing stickers on a hydro flask.

Points to Consider

1. Choose the Right Stickers

When selecting stickers for your hydro flask, opt for those specifically designed for water bottles or hydro flasks. These stickers are made from durable materials that can withstand exposure to moisture.

2. Clean the Surface

Prior to applying any stickers, thoroughly clean the surface of your hydro flask using warm water and mild soap. This step ensures that there are no dirt, oils, or residue that could interfere with the adhesion of the stickers.

3. Dry the Surface

Once the surface is clean, ensure that it is completely dry. Moisture can hinder the adhesive properties and cause the stickers to peel off easily. Allow the hydro flask to air dry or use a clean cloth to dry it manually.

4. Position the Sticker

Decide where you want to place the sticker on your hydro flask. Carefully peel off the backing of the sticker and align it with the desired location. Take your time to position it accurately, as readjusting once it sticks can be difficult.

5. Smooth Out Air Bubbles

To prevent air bubbles, slowly smooth out the sticker from the center towards the edges using your fingers or a credit card. This gradual approach ensures a seamless application and eliminates any trapped air bubbles.

6. Seal with a Protective Coating

For added protection, consider applying a clear sealant or mod podge over the sticker. This protective coating will guard the sticker against water and sunlight exposure. Follow the manufacturer's instructions for the specific product you choose.

7. Let it Dry

Allow both the sticker and the protective coating, if applied, to dry completely before using your hydro flask. This ensures a strong and long-lasting bond between the sticker and the surface of the flask.


By following these steps, you can confidently seal stickers on your hydro flask, adding a personalized touch while ensuring their durability. Remember to clean and dry the surface, position the sticker carefully, smooth out air bubbles, and apply a protective coating if desired. Enjoy your customized hydro flask for years to come!


Q: How long does the protective coating take to dry?

A: The drying time for the protective coating varies depending on the product. Refer to the instructions provided by the manufacturer for the specific drying time.

Q: Can I remove the stickers easily if I want to change the design?

A: With proper adhesion and sealing, removing the stickers might be more challenging. However, if desired, you can use heat (such as a hairdryer) to loosen the adhesive and carefully peel off the stickers from your hydro flask.

Q: Can I seal any type of sticker on a hydro flask?

A: It is recommended to use stickers specifically designed for hydro flasks or water bottles, as they are made from materials that are better suited for these surfaces and can withstand exposure to moisture.
