J-B MarineWeld is a specially formulated two-part epoxy cold weld system that provides for strong, lasting repairs for bonding different or similar surfaces, such as aluminum, metal, composites, fiberglass and others. MarineWeld sets in 20-25 minutes at room temperature and is fully cured to a dark grey color in 15-24 hours. Once cured, it can be shaped, tapped, filed, sanded and drilled and will retain its strength above or below the waters’ surface. MarineWeld has a 1:1 mixing ratio and tensile strength of 3960 PSI.

INSTRUCTIONS

Prepare: Clean surface area of dirt, grease, oil, paint or loose debris.*

Mix: Squeeze equal parts from each tube onto a disposable surface and mix thoroughly.

Apply: Apply with appropriate tool in an even coat, weld bead or extruded shape as needed.

Dry: Sets in 20-25 minutes. Cures in 15-24 hours. Allow 4-6 hours before handling and 15 hours (min.) before putting object back in use.

 

* For best results use a detergent or degreaser to first clean the surface, then roughen surface with file or coarse sandpaper to provide the best repair.

    Just wanted to thank you for making a product that does exactly what it claims to do . . . and does it remarkably well. I dropped the outboard in my small car-topper aluminum boat and punctured it (right through). WaterWeld did a phenomenal job fixing my boat. It has not moved or leaked since I fixed it. Fish on!
