Hoe kan ik naden waterdicht maken?

Camping is great, right? The smell of nature, the sound of birds in the morning and the soothing atmosphere of the outdoors. But there is one thing every camper will agree on: leaking tents are a nightmare, especially in the rain. Fortunately, we have the solution for you: tent seam waterproofing.

Why do tent seams leak?

Before we share the solution, let's look at the main causes of leaking tent seams:

  • Seam wear: This is where two pieces of tent fabric are joined, making it a vulnerable point.
  • Wear ofthe seam-tape: This wear is especially common with synthetic tent fabrics.
  • Stitch thread wear: The stitching thread can deteriorate over time, especially the cotton sheathing.

Tip: Just got a new cotton tent? Wet the tent fabric before you go on vacation. That way the yarns expand and the seams are immediately waterproof!

The solution: Sprayhood & Tent Protector impregnator 👍

Impregnating your tent is the most effective way to prevent leaks. We highly recommend Ultramar's Sprayhood & Tent Protector. Why.

  • Suitable for all types of canvas: tents, boat covers, convertible roofs and more.
  • It not only makes your tent waterproof, but also dirt repellent.
  • Less chance of mold, algae and other dirt.
  • The tent fabric stays beautiful longer and is easier to keep clean.

Instructions for use:

  • Make sure the canvas is clean and dry.
  • Spray the dry canvas generously.
  • Spread the impregnating agent evenly.
  • If possible, also apply on the inside.
  • Be careful with plastic windows: remove the agent from them immediately.
  • Let the cloth dry thoroughly.

Tip: Before impregnating your tent, check the stitching. If the stitching is worn, it may be time to consult an expert.

Other ways to maintain your tent:

  • Remove stains immediately.
  • Clean after each use.
  • Make sure the tent is thoroughly dry before storing.
  • If necessary, apply seam tape for extra protection.

Tip: Don't rely on seam sealers. They can leave unsightly streaks and are not as effective as a good impregnator.
