How to Build a Tiny Electronic Patch That Makes Your Phone Waterproof Using Stuff You Already Have Around the House

Making your phone waterproof can seem daunting, but with a few simple household items you likely already have, you can create a tiny electronic patch to keep your phone protected. This cheap and easy method will allow you to use your phone worry-free around water without spending money on a bulky waterproof case.

What You'll Need

How to Make the Patch

Step 1: Cut the Plastic Base

Use scissors to cut your plastic sheet down to a size that will fully cover the charging port/earphone jack area of your phone. Leave some extra room on the edges for the tape border. Cutting a rectangle an inch or two wide usually works well.

Step 2: Clean the Phone

Use a cloth or cotton pad dampened with rubbing alcohol to clean the area where you'll apply the patch. This helps the adhesive stick firmly. Make sure to clean both the phone and the plastic base piece.

Step 3: Apply Tape

Place the plastic directly over the port area on the phone. Apply strips of clear packing tape over the plastic piece and phone surface until completely covered and firmly adhered. Press the tape down firmly as you apply it, smoothing out any air bubbles.

Step 4: Seal the Edges

Apply additional strips of tape extending at least 1/2 inch beyond the edges of the plastic, adhering them to the phone surface. This seals up and waterproofs the edges.

Step 5: Check Adhesion

Once assembled, firmly press and smooth the whole patch to maximize adhesion. Ensure the tape is stuck tightly with no lifts at the edges.
