Materials Needed

Before you embark on making your phone waterproof, it’s important to gather all the necessary materials. Here’s a list of what you’ll need:

  1. Waterproof Sealant: Look for a high-quality waterproof sealant specifically designed for electronic devices. Silicone-based sealants work well as they create a protective barrier against water.
  2. Plastic Gloves: Wearing gloves while working with sealant helps prevent any unwanted mess or residue on your hands.
  3. Microfiber Cloth: You’ll need a clean, lint-free cloth to wipe down your phone and ensure there is no dust or debris before applying the sealant.
  4. Masking Tape: This will come in handy to cover certain areas of your phone that you don’t want to be sealed, such as the charging port or headphone jack.
  5. Small Brush: A small brush, like a paintbrush or a soft toothbrush, will be useful for applying the sealant evenly and precisely.
  6. Plastic Sheet or Bag: To protect your work surface from any accidental spills or drips, lay down a plastic sheet or bag.
  7. Hairdryer (Optional): If the sealant you’re using requires heat for proper curing, having a hairdryer on hand can help speed up the process.

Gathering these materials beforehand will ensure a smooth and efficient process when making your phone waterproof. Now that you have everything you need, let’s move on to the next step: preparing the phone.

Preparing the Phone

Before attempting to make your phone waterproof, it’s crucial to adequately prepare it. This preparation process will help ensure that the waterproofing method is effective and doesn’t cause any damage to your device.

The first step is to clean your phone thoroughly. Remove any dirt, dust, or fingerprints from the surface of the phone using a microfiber cloth or a screen cleaning solution. This is important because any debris can hinder the adhesion of the waterproof sealant.

Next, you’ll want to inspect your phone for any existing damage, such as cracks or gaps. If your phone has any pre-existing issues, it’s best to get them fixed before attempting to make it waterproof. The waterproofing method will work best on a phone that is in good condition.

It’s also essential to check the manufacturer’s guidelines or warranty information for your specific phone model. Some manufacturers may have specific instructions regarding waterproofing or may offer official waterproofing services for their devices. Following these guidelines can help you avoid voiding the warranty or damaging your phone.

If your phone has removable parts, such as a back cover or battery, ensure they are securely in place before proceeding. Loose or improperly fitted components may compromise the effectiveness of the waterproofing.

Lastly, make sure your phone is fully charged before starting the waterproofing process. This is important because once the waterproof sealant is applied, you’ll want to avoid opening or powering off your phone for a certain period to allow the sealant to cure properly.

By properly preparing your phone, you’ll maximize the chances of successfully waterproofing it without causing any harm to the device. Take your time during this stage to ensure that your phone is clean, in good condition, and ready for the waterproofing process.

Applying a Waterproof Sealant

Once your phone is fully prepared for waterproofing, it’s time to apply a waterproof sealant. A sealant is a protective coating that helps prevent water from seeping into your device. Here’s a step-by-step guide on how to apply a waterproof sealant:

1. Choose the Right Sealant: There are various types of sealants available in the market, so it’s important to choose one specifically designed for electronic devices. Look for sealants that provide a waterproof barrier without hindering the functionality of your phone.

2. Follow the Instructions: Carefully read the instructions provided by the manufacturer before applying the sealant. Different sealants may have slightly different application methods, so it’s important to follow the specific instructions for optimal results.

3. Apply Evenly: Using a clean and soft brush or applicator, apply the sealant evenly on the surface of your phone. Pay extra attention to the areas that are more prone to water damage, such as the charging port, headphone jack, and buttons.

4. Allow Proper Drying Time: After applying the sealant, make sure to allow proper drying time as mentioned in the product instructions. This step is crucial to ensure that the sealant forms a protective barrier and adheres firmly to the surface of your phone.

5. Check for Bubbles or Imperfections: Once the sealant has dried, carefully inspect your phone for any bubbles or imperfections. If you notice any, gently remove them using a toothpick or a soft cloth. A smooth and even application of the sealant is necessary for effective waterproofing.

6. Apply Multiple Coats (Optional): If you want to add an extra layer of protection, you can apply multiple coats of the sealant. Just make sure to follow the recommended drying time between each coat to allow proper bonding.

7. Reassemble Your Phone: Once you’re satisfied with the sealant application and it has fully dried, carefully reassemble your phone by placing the battery, back cover, and any other removed components back in their respective positions.

Following these steps will help you effectively apply a waterproof sealant to your phone and minimize the risk of water damage. However, it’s important to remember that even with a sealant, complete immersion in water should be avoided, as it may still cause damage to your device.

Testing the Waterproofing

Once you have applied the waterproof sealant to your phone and allowed it to dry, it’s time to put it to the test. Follow these steps to ensure that your phone is effectively waterproofed:

Step 1: Submerge the Phone

Fill a container with water, ensuring that it is deep enough to completely submerge the phone. Carefully place your phone in the container, making sure that it is fully immersed in water.

Step 2: Observe for Leaks

Keep a close eye on your phone as it is submerged. Look for any signs of moisture or water seeping into the phone’s interior. Pay attention to areas where the sealant was applied. If there are any leaks, you may need to reapply the sealant and repeat the drying process.

Step 3: Test Functionality

While the phone is submerged, test its functionality. Try pressing the buttons, using the touchscreen, and making calls. Make sure that the phone is still responsive and that there are no issues with its performance.

Step 4: Duration Test

Leave the phone submerged in water for an extended period of time, such as 30 minutes to an hour. This will simulate exposure to water in real-life scenarios, such as accidental submersion in a pool or rain. After the designated time, remove the phone from the water.

Step 5: Dry and Inspect

Once you have finished the duration test, carefully remove the phone from the water and dry it thoroughly. Use a soft cloth or towel to remove any excess moisture. Inspect the phone for any signs of water damage or malfunction. If everything looks good, congratulations! You have successfully waterproofed your phone.

It’s important to note that while waterproofing your phone can provide some protection against water damage, it is not foolproof. It is always recommended to exercise caution and avoid exposing your phone to excessive water or submersion for prolonged periods of time.

Remember that testing the waterproofing of your phone should be done in a controlled environment and at your own risk. If you are unsure or uncomfortable performing these tests yourself, it is best to consult with a professional.

Additional Tips and Precautions

When it comes to making your phone waterproof, there are a few additional tips and precautions to keep in mind. These measures can further protect your phone from water damage and ensure that your waterproofing efforts are successful.

1. Avoid excessive water exposure: While making your phone waterproof can provide a certain level of protection, it’s important to remember that it is not completely waterproof. Therefore, it’s best to avoid unnecessary exposure to water. Try to keep your phone away from water sources such as swimming pools, oceans, or heavy rain.

2. Regularly check the waterproof sealant: Over time, the waterproof sealant may wear off or become damaged. It’s essential to regularly inspect the sealant and reapply it if necessary. This will help maintain the integrity of the waterproofing and prevent any potential water leaks.

3. Use a waterproof phone case: If you want an extra layer of protection for your phone, consider investing in a waterproof phone case. These cases are specifically designed to keep your phone safe from water damage. Make sure to choose a high-quality case that fits your phone model for optimal protection.

4. Handle with care: Although your phone may be waterproofed, it’s crucial to handle it with care. Avoid dropping it or exposing it to extreme temperatures. Mishandling your phone can still lead to internal damage, even if it’s been waterproofed.

5. Don’t submerge your phone for extended periods: While your phone may be able to withstand some water exposure, it’s important not to deliberately submerge it for extended periods. Prolonged immersion in water can still cause damage to the internal components of your phone, even with waterproofing measures in place.

6. Keep your phone clean and dry: Regularly clean your phone and make sure it stays dry. Use a soft, lint-free cloth to wipe away any moisture, dirt, or dust. Keeping your phone clean and dry will help maintain its performance and prevent any potential water-related issues.

7. Follow manufacturer guidelines: Different phone models may have specific instructions and guidelines when it comes to waterproofing. Always refer to the manufacturer’s recommendations to ensure you are following the proper steps and using compatible sealants or waterproof cases.

By following these additional tips and precautions, you can help maximize the effectiveness of your waterproofing measures and minimize the risk of water damage to your phone. Remember, prevention is always better than dealing with costly repairs or replacements, so take the necessary steps to protect your device.


In conclusion, making your phone waterproof is an essential step in protecting your investment and ensuring its longevity. With the wide range of waterproof cases, pouches, and coatings available today, there are plenty of options to suit your needs and budget.
