How to Create A Waterproof Seal For My Tarp?

April 5, 2026

Quick Answer

Create a waterproof seal for your tarp by using a combination of a tarp clip or cord tightener, a few turns of paracord or cordage, and a knot, such as a bowline or trucker's hitch, to secure it tightly and prevent water from seeping in.

Preparing the Tarp Seal

Before creating a waterproof seal, ensure your tarp is properly installed and tied down with a sturdy lean-to structure. This includes securing the tarp to the frame with a few turns of paracord or cordage to create a taught surface. Use a tarp clip or cord tightener to pull the tarp taut, eliminating any sagging or wrinkles that could compromise the waterproof seal.

Creating the Waterproof Seal

To create the waterproof seal, wrap a few turns of paracord or cordage around the tarp clip or cord tightener, overlapping the turns by at least 1-2 inches. Then, tie a bowline or trucker’s hitch knot to secure the paracord in place, making sure it is snug and even. This knot will keep the tarp tight and prevent water from seeping in through the clip or tightener.

Reinforcing the Waterproof Seal

To further reinforce the waterproof seal, use a small amount of waterproof adhesive, such as silicone or beeswax, to seal any gaps or holes around the tarp clip or cord tightener. This will provide an additional layer of protection against water ingress. Additionally, consider adding a few extra turns of paracord or cordage around the seal to provide extra security and prevent any potential water leaks.
