For tarp repair, the most widely recommended adhesive out there is HH-66 Vinyl Cement.
The world’s most powerful PVC vinyl adhesive is also the top choice of the international association representing manufacturers of truck tarps, agricultural tarps, waste tarps and gym floor covers.
Why? No glue works better. HH-66 is waterproof, sets with a single application, and bonds vinyl to itself with a seal stronger than the fabric.
If your tarp or gym floor cover is too important for a tear, HH-66 is the tool for you.
Please note that tarps made of polyethylene (typical “blue tarp” material) – sometimes called “poly tarps” – or with extremely thin vinyl (used for lettering or wraps) are not compatible with our products.
