It takes minutes to create a seam seal that’s stronger than the tarps themselves.

When you’re using tarps for weatherproofing or containment, partial coverage is no coverage at all.

That’s why knowing how to make a strong seam seal is an essential part of customizing tarps. Modifying tarps for your job’s needs is powerful – if you combine tarps effectively. If not, you’re waiting for an accident to happen.

HH-66 is the only adhesive recommended by the Advanced Textiles Association for tarp repair. Here’s how 5 minutes with the right glue can get you the custom tarp coverage you need.
