That's a common issue, and fixing it yourself is totally doable! A small crack in a plastic outdoor trash bin can lead to leaks and worsen over time. The best repair method depends on the plastic type and crack size, but here are the most effective DIY solutions.
First, clean and dry the area thoroughly. For a permanent, waterproof fix on rigid plastic, a two-part plastic epoxy or plastic welding kit is your best bet. Apply the epoxy according to the instructions, ensuring it seals both inside and out. For a flexible polyethylene bin (common for wheeled models), a specialized polyethylene repair adhesive or a plastic welding technique with a soldering iron and matching plastic filler works wonders.
For a quick, temporary seal, consider a strong, waterproof repair tape like fiber-reinforced or silicone tape, applied tightly over the clean, dry crack. While not as permanent, it can effectively stop leaks.
The key is to act quickly before the crack spreads. With the right prep and material, your repaired bin will be back in service, saving you money and keeping your outdoor area clean.
