Discovering a crack in your outdoor trash bin lid can be frustrating, but before you consider replacement, try these effective repair methods that can save you money and extend your bin's life.
For plastic bin lids, plastic welding creates the most durable repair. Clean the cracked area thoroughly with soap and water, then dry completely. Using a plastic welding kit or soldering iron with a plastic welding attachment, gently melt the plastic along the crack while applying compatible plastic welding rods to fuse the material together. Work in sections, applying moderate pressure to ensure proper bonding. Once cooled, sand the repair smooth for a professional finish.
For those without welding equipment, two-part epoxy designed for plastic provides a strong alternative. After cleaning and roughing the area around the crack with sandpaper, mix the epoxy according to package directions. Apply generously over and into the crack, then use a clamp or weight to hold the pieces together while curing. For extra reinforcement, consider adding a fiberglass mesh patch between epoxy layers.
Small hairline cracks respond well to waterproof flexible sealants. Silicone-based products work particularly well as they remain flexible through temperature changes. Apply the sealant, smooth with a putty knife, and allow full curing time before use.
Prevention remains crucial - avoid overloading your bin and keep it out of direct sunlight when possible. Regular inspection and minor repairs can prevent small cracks from becoming major problems. With these techniques, your repaired bin lid should provide years of additional service.
