Seam Grip +SIL works great with our Nylon Trekker Tents.  Use it to repair small holes in outdoor fabrics, seam seal a tent, or fix tears. Works on silicone-coated fabrics.

Seam sealing with Seam Grip SIL is the best way to keep moisture out when using a silnylon (silicone-nylon) tent. Previously known as SilNet, this clear sealant dries to a flexible rubber that works on all silicone treated gear including nylon tarps and ultralight backpacks. A single 1.5 oz tube can seal up to 24 ft of seams. Fast and easy to use, it’s also handy for pinhole repairs and small tears. When you need to waterproof a silnylon tent only a silicone sealant will work, because silicone will only adhere to silicone. So, treat gear right and seal out the weather with Seam Grip SIL.

  • Waterproof – Provides a water-tight seal that won’t peel or crack over time, keeping you warm and dry

  • Flexible – Cures to an elastic, rubber seal that flexes and stretches with high performance gear
  • Weather-resistant – Tough formula is not affected by extreme heat or cold


  • Size: 1.5oz (42g) tube

How to use for seam sealing

  1. Ensure seams are clean and dry.
  2. Apply a thin layer across the seam threads. For our Trekker Tents we recommend applying to the outer seams of the tent. We also recommend applying a layer to the inside corner seams over/around the seam tape.
  3. Allow to cure for 8-12 hours.

How to use for repairs

  1. Ensure surface of fabric is clean and dry.
  2. For large holes or rips use tape (such as tenacious Tape) to create a backing.
  3. Fill the hole with sealant, extend at least a 1/4in past the damaged area.
  4. Keep level and allow to cure for 8-12 hours.
  5. You can remove the tape once cured.
