What are the best adhesives for repairing cracks in polyethylene outdoor seating?

Repairing cracks in polyethylene outdoor seating requires adhesives that bond well with plastic and withstand outdoor conditions. Here are the best options:

1. Epoxy Adhesives: Two-part epoxy provides a strong, durable bond for polyethylene. Look for formulas specifically designed for plastic repair.

2. Polyurethane Glue: Flexible and waterproof, polyurethane glue is ideal for outdoor use. It expands slightly to fill cracks.

3. Specialized Plastic Adhesives: Products like Loctite Plastics Bonding System or 3M Scotch-Weld are formulated for polyethylene and similar plastics.

4. Cyanoacrylate (Super Glue): Works for small cracks but may not be as durable for large repairs.

For best results, clean the surface thoroughly and lightly sand it before applying the adhesive. Clamp or weigh down the repaired area until fully cured. Choose a product with UV resistance for long-lasting outdoor repairs.
