A leaking pool float doesn’t mean it’s time to throw it away. With the right tools and some care, you can easily fix it at home. This guide explains how to locate the leak, choose the right materials, apply the patch properly, and keep your float lasting for many more swims.
Locate the leak
Inflate the float to about half its normal firmness. Mix dish soap with water and brush it across the seams, body, and valve. Watch for steady small bubbles — that’s where air is escaping. Mark each spot with tape or a marker. If the bubbles come from the valve, you might need a valve-specific fix rather than a patch.
Deflate and dry
Once you’ve marked the leak, deflate the float until it’s soft. Clean the damaged area with rubbing alcohol or mild detergent to remove dirt, oils, and sunscreen residue. Allow it to dry fully. For vinyl materials, lightly roughen the surface with fine sandpaper — it helps the glue bond better.
Prepare the patch
Use a patch that matches the float’s material (usually PVC or TPU). Cut a piece at least 2 cm larger than the hole in every direction, rounding the edges to prevent peeling. Place it over the hole to ensure full coverage before gluing.
For vinyl or PVC floats
Use a vinyl cement or repair adhesive designed for inflatables.
Apply a thin, even layer of glue to both the float and the patch.
Wait 1–2 minutes until both surfaces feel tacky.
Carefully align and press the patch over the hole, smoothing from the center outward to remove air bubbles.
Press firmly for a few minutes using your fingers or a flat object.
Let it cure for at least 12–24 hours before inflating.
For TPU or specialty materials
Use a flexible polyurethane adhesive.
Apply a light layer of glue to the patch only.
Wait a few minutes until it becomes sticky.
Press the patch evenly onto the float and hold for one minute.
Wipe excess glue and leave it flat for 24 hours to cure completely.
Peel-and-stick patch option
If you need a fast fix, a self-adhesive patch works for small holes. Clean and dry the surface, peel off the backing, and press the patch firmly from the center outward. Wait several hours before use. It’s quick, but less durable than glued repairs.
Double patch for larger damage
For long tears or high-stress areas near seams, apply one patch inside and another outside. Align both and press firmly. Keep the float flat for at least 48 hours for a solid bond.
After curing, inflate slowly. Add air in small stages, checking that the patch edge doesn’t lift. Never overinflate — air expands in heat and can stress the repair.
Once firm, brush a thin soapy layer around the patched area and watch for bubbles. No bubbles mean success. If a slow leak appears, deflate slightly, seal the edge with a drop of glue, and allow it to dry again.
Rinse the float after use to remove chlorine and sunscreen, and dry it before storage. This prevents residue from weakening the adhesive over time.
Avoid rough surfaces
Sharp edges and pool tiles can puncture thin vinyl. Always lift the float instead of dragging it. Laying a towel or mat underneath adds protection.
Mind the temperature
Hot sun expands internal air, increasing pressure on seams. Slightly under-inflate the float if it will sit in direct sunlight. The material should feel firm but still flexible.
Handle gently
Avoid jumping or standing on floats. Concentrated weight causes tiny splits that spread with time. Encourage smooth, even use — especially for children’s inflatables.
Proper storage
Deflate fully after the season, roll (not fold) the float loosely, and store it in a cool, dry place. Avoid heat and humidity, which can weaken both the material and your patch.
Protect frequent contact zones
If your patch sits where people often climb on, apply a transparent protective film over it after curing. It spreads stress and prevents peeling.
Repairing a pool float is simple if done carefully. Clean the surface, match the right patch and adhesive, and give it enough time to cure. With routine maintenance and mindful use, a single repair can last for many months of summer fun — saving you money and reducing waste while keeping your float ready for every splash.
