Inflatable Kayak

When you think of the perfect day on the water with your inflatable kayak, the last thing you want to worry about is dealing with mould and mildew when it’s time to pack up. Unfortunately, if you don’t take the right precautions, these pesky invaders can make their way onto your kayak, leading to unsightly stains, a bad smell, and even damage that can shorten the lifespan of your kayak.

The good news? Preventing mould and mildew is easier than you might think. With a little maintenance and upkeep, it's possible to keep your inflatable kayaks in top condition for years to come. 

Let’s dive into why mould and mildew happen, the risks they pose, and how you can counteract them with a few practical measures!

Why Do Mould and Mildew Form on Inflatable Kayaks?

Mould and mildew thrive in damp environments. When you’re out paddling on the water, your kayak is exposed to plenty of moisture. Combine that with mild temperatures and the fact that inflatables often don’t get the same airflow as rigid kayaks, and you’ve got the perfect breeding ground for mould and mildew.

The materials used in inflatable kayaks (especially PVC and rubber), can sometimes trap  moisture if they are left wet and not dried properly before being packed away. When left unchecked, mould and mildew may grow on both the surface and inside the air chamber.

While they may seem innocuous, they actually pose potential health hazards for you and your fellow paddlers. This is because mould spores could cause everything from allergies to respiratory irritation and infections—particularly if exposure is prolonged.

That’s why regular maintenance and cleaning are essential. 

The Consequences of Mould and Mildew

It’s easy to dismiss a little bit of mould here and there as harmless, but the truth is, these fungi can cause significant damage over time:

  • Aesthetic Damage: Mould and mildew will leave unsightly stains on your kayak, which can be tough to remove if left untreated.
  • Material Breakdown: Mould can weaken the fabric and seams of your inflatable kayak, making it more susceptible to leaks and punctures. Over time, this may compromise your kayak’s structural integrity.
  • Health Risks: Mould spores are known to cause respiratory issues and allergic reactions. Prolonged exposure may even lead to infections, especially if you’re particularly sensitive to mould.

How to Prevent Mould and Mildew on Your Inflatable Kayak

The key to keeping inflatable kayaks free of mould and mildew is consistent care and attention. Follow the steps below to make sure your kayak stays dry, clean, and in great condition.

1. Rinse Your Kayak After Every Use

After each outing, especially in saltwater, it’s essential to give your kayak a thorough rinse with fresh water. Saltwater, pollutants, and debris from the water all have the potential to build up on your kayak. In turn, this increases the risk of corrosion and encourages the growth of mould.

Step-by-Step Rinsing Process:

  • Remove any accessories, seats, or removable parts from the kayak.
  • Rinse the entire kayak with fresh water, paying special attention to seams and crevices where salt or dirt can get trapped.
  • Be sure to close the valves before rinsing to avoid water getting into the air chambers, which could lead to internal mould growth.

Tip: Use a gentle spray rather than a powerful jet of water to avoid damaging the kayak.

2. Dry Your Kayak Thoroughly

Drying your inflatable kayak after every use is arguably the most crucial step in preventing mould and mildew. Mould thrives in damp environments, so eliminating moisture from the water is key.

How to Properly Dry Your Inflatable Kayak:

  • After rinsing, use a microfiber towel to wipe down the entire kayak, including hard-to-reach areas.
  • Open the valves to make sure that no moisture is trapped inside the air chambers.
  • Leave your kayak in a shaded, well-ventilated area to air dry completely. Avoid direct sunlight for extended periods, as this can damage the kayak’s material.
  • If you need to pack up quickly, at least make sure you dry the kayak as much as possible and unfold it at home to dry completely before storing it.

Tip: Bring along an old towel on your paddling trips for quick drying, especially if you’re on the go and don’t have time for a thorough clean.

3. Clean Your Kayak Regularly

Regular cleaning is essential for maintaining the condition of your inflatable kayak. Beyond rinsing, you’ll want to give your kayak a deep clean at least a few times a season to remove any oil, dirt, or sunscreen that may have built up on the surface.

What You’ll Need for Cleaning:

  • Microfiber cloths
  • A soft sponge
  • Mild natural soap or kayak cleaner
  • Freshwater supply (hose or bucket)
  • UV-protectant spray

Step-by-Step Cleaning Process:

  • Fully inflate the kayak and inspect it for any damage, dirt or debris.
  • Use a soft sponge and mild soap to clean the entire surface of the kayak. Avoid harsh chemicals, as these can degrade the material over time.
  • Pay special attention to the valves, seams, and any other areas that may trap dirt.
  • Rinse the kayak thoroughly with fresh water.
  • Allow the kayak to air dry completely before applying UV protectant.

4. Apply a UV Protectant

Consistent exposure to the sun’s ultraviolet rays could weaken your inflatable kayak’s material over time, making it more prone to damage and deterioration. Applying a UV protectant spray, therefore, allows you to extend the life of your kayak and add an extra layer of defence against the elements.

How to Apply UV Protectant:

  • After your kayak is fully cleaned and dried, spray the entire surface with a UV protectant spray.
  • Use a microfiber cloth to evenly spread the protectant across the kayak, ensuring all areas are covered.
  • Let the kayak air dry for a few minutes before deflating and storing.

Tip: Use a protectant that’s specifically designed for inflatable kayaks or PVC materials to avoid any potential damage.

5. Store Your Kayak in a Dry, Cool Place

Proper storage is essential for preventing mould and mildew from forming on your kayak during the off-season or between uses. Leaving your kayak in a damp or humid area can actually undo all the hard work you put into cleaning and drying it.

Best Practices for Storing an Inflatable Kayak:

  • Make sure the kayak is completely dry before deflating and packing away.
  • Store the kayak in a cool, dry place. Avoid areas with high humidity, such as a damp basement.
  • If possible, store the kayak slightly inflated to reduce stress on the seams and materials, but ensure it’s not exposed to heat or direct sunlight.
  • If you’re packing it away in a travel bag, leave the bag slightly open to allow for airflow and prevent any residual moisture from getting trapped.

Tip: Storing the kayak on a raised surface, like a shelf, can help keep it away from moisture that might accumulate on the ground.

6. Rotate Your Kayak’s Fold

As you pack up the kayak, try to avoid folding it the same way every time. Constant folding along the same creases can cause weak spots in the material, which can lead to tears and leaks.

How to Fold Your Kayak:

  • Deflate the kayak completely and open all valves to ensure there’s no trapped air.
  • Fold the kayak loosely, avoiding sharp creases in the same places each time.

This simple habit could go a long way to prevent unnecessary stress on the kayak’s seams and extend its lifespan.
