What You'll Learn
Use a drum leak repair kit
If you're looking for a quick and convenient way to repair a leaking plastic drum, a drum leak repair kit is an ideal solution. These kits are designed to address various types of damage, including punctures, cracks, gashes, and surface rot in plastic drums. They offer a temporary fix to stop leaks and salvage your drum, preventing content loss and minimising clean-up efforts.
Drum leak repair kits come with a comprehensive set of tools and hardware, offering a one-stop solution for your repair needs. The kits typically include a range of ball plugs, surface plugs, wedges, patches, tapes, and repair putty. Some kits may also provide basic tools, such as screwdrivers, safety hammers, rubber mallets, and pliers, to facilitate the repair process.
One of the critical components of the kit is the epoxy putty, which can effectively seal small holes and cracks in plastic drums. This putty cures within 20 minutes, hardening like steel, and is suitable for various surfaces beyond plastic, including metal, glass, and ceramic. For hairline cracks, stress fractures, and weld connections, lead wool can be packed into tight spaces using a screwdriver or knife.
To address larger holes, wooden wedges or plugs can be hammered into place using a rubber mallet. These wedges can be used alone or in combination with an absorbent pad for added effectiveness. Additionally, stainless steel sheet metal screw patches with neoprene compression seals can restrict and stop the flow through pinholes, providing a secure seal.
Drum leak repair kits are designed with portability and convenience in mind. They are often packaged in a heavy-duty metal storage box or carry case with a latched lid, making it easy to store and transport the kit to the repair site. The kits are available with different tool options, including standard steel and non-sparking tools, depending on whether you're working with flammable or combustible materials.

Sealants and glue for small holes and cracks
Plastic drums are robust and long-lasting, but they can still sustain damage. When cracks or holes appear, there are a variety of sealants and glues that can be used to repair them.
For small holes and cracks, a dedicated plastic sealant can be used to fix leaks and provide a new waterproof layer. Silicone sealants, for example, are flexible, gap-filling, temperature-resistant, and can act as both a sealant and adhesive. They are ideal for bonding with ABS plastics, rubbers, and more. Loctite Clear Silicone Waterproof Sealant is a good example of this type of product.
Two-part plastic adhesives and epoxies are another option for repairing small holes and cracks in plastic drums. These usually come in tubes with plungers and require mixing the two components before application or priming the surface before applying the adhesive. They are designed to adhere to hard-to-bond surfaces like PP and PE plastics. Loctite Metal and Concrete Epoxy is a good choice for repairing holes and cracks in plastic.
Single-tube plastic sealants are also available and provide a flexible seal. These are intended for use with softer plastics. Some products, like the Loctite Plastics Bonding System, are specifically formulated to bond with challenging materials like polyethylene, polypropylene, and Teflon.
When choosing a sealant or adhesive, it is important to consider the type of plastic and the size of the hole or crack. Always follow the manufacturer's instructions for compatibility, application techniques, delivery systems, and cure times.

Proper handling and storage
Plastic drums are a versatile and durable storage solution for liquids, powders, and granulated solids. However, leaks can occur due to various factors, and proper handling and storage are crucial to prevent them. Here are some detailed guidelines for the proper handling and storage of plastic drums to minimise the risk of leakage:
Proper Handling:
- Avoid rough handling: Be cautious during loading, unloading, and transportation. Ensure the drums are not knocked over, dropped, or subjected to impacts, as this can cause dents, warping, or cracks.
- Secure lids and openings: Always securely tighten and fasten lids and bung openings before moving the drums. This prevents gradual spilling during transport or handling.
- Use caution with stacking: When stacking drums for storage, use proper staggering and stacking techniques. Avoid stacking them too high, and always use protective padding between layers to prevent denting, warping, or cracking.
- Handle with care: Always handle drums gently to prevent damage that can lead to leaks.
Proper Storage:
- Regular maintenance: Maintain the drums with regular interval inspections and cleaning. This helps identify any signs of wear and tear, such as scratches, cracks, or punctures, and allows for timely repairs.
- Protect from elements: Shield drums from harsh weather conditions, including extreme heat, cold, and UV rays, as these can weaken the plastic over time.
- Store on a level surface: Ensure the drums are stored on a flat, even surface to distribute weight evenly and prevent stress points that could lead to leaks.
- Check inlet and outlet connections: Inspect the inlet and outlet points for proper connections. Ensure fittings for pipes, hoses, or valves are secure, tight, and correctly sealed to prevent leaks at these vulnerable points.
- Replace old drums: Drums have a recommended lifespan. Proper inspection and scheduled replacement of aged drums can reduce the likelihood of leaks due to corrosion and seam failure.
- Use leak repair kits: In case of leaks, promptly address them with dedicated leak repair kits. These kits provide temporary repairs with ball plugs, surface plugs, wedges, patches, tapes, and repair putty.
By following these proper handling and storage guidelines, you can effectively minimise the risk of leakage in plastic drums and extend their lifespan.

Regular maintenance and inspection
Maintenance Schedule: Establish a routine maintenance schedule for your plastic drums, which includes periodic inspections, cleaning, and, if necessary, repairs. The frequency of inspections and maintenance tasks may vary depending on the usage, environment, and specific recommendations from the manufacturer.
Inspection: During each inspection, thoroughly examine the plastic drum for any signs of damage, including cracks, scratches, dents, or punctures. Pay close attention to areas that are more susceptible to damage, such as seams and edges, as these tend to corrode or wear out over time. Also, check for any loose components, such as handles, lids, or nozzles, and ensure that all connections at inlet and outlet points are secure and properly sealed. Keep an eye out for any signs of corrosion or degradation, as this can weaken the drum and increase the likelihood of leaks.
Cleaning and Repair: Regular cleaning of the plastic drums is essential to maintain proper hygiene and prevent the buildup of dirt or debris, which could contribute to deterioration. When cleaning, be gentle to avoid causing accidental scratches or damage. If you identify any issues during the inspection, address them promptly. For minor issues, such as small cracks or loose components, you can use dedicated plastic sealants or industrial-strength glue as a temporary fix. Ensure you follow instructions carefully and choose products suitable for the specific type of plastic your drum is made of.
Preventative Measures: To reduce the likelihood of leaks, always handle and store your plastic drums with care. Avoid rough handling, collisions, or dropping the drums, as this can lead to dents, warping, or cracks. Properly secure the lids or bung openings before moving or transporting the drums to prevent gradual spills. Additionally, ensure drums are stacked correctly during storage, with proper staggering, protective padding, and adherence to stacking limits to avoid excess weight damaging the lower drums.
By implementing these regular maintenance and inspection procedures, you can effectively prevent leaks, extend the lifespan of your plastic drums, and maintain the integrity of the stored contents.
