There are several ways to mend a broken plastic bucket, depending on the type of break. For small cracks, plastic glue, hot water, or plastic slurry can be used. Plastic glues are readily available at hardware stores and are formulated to create strong bonds between plastic surfaces. Alternatively, a strong chemical solvent like acetone can dissolve plastic, allowing it to be painted onto the damaged area. For larger cracks, welding with a soldering iron may be necessary. This involves melting plastic strips and applying them to the crack, potentially with metal reinforcement. Another method involves spraying a rubber coating on the crack, but this may not be suitable for holding liquids.

Using glue to mend a broken plastic bucket
Mending a broken plastic bucket with glue is a simple and effective method. You can use plastic glue, super glue, or a strong adhesive to fix the crack in your bucket. Here is a step-by-step guide:
Prepare the Glue and Bucket:
First, ensure you have enough glue to complete the repair. Plastic glue is ideal, but super glue or strong adhesives can also work, as long as they are suitable for plastic. Standard glue may not be strong enough, so opt for a specialized plastic glue if possible. You can find these at your local hardware store or home improvement center. Wear rubber gloves to protect your hands from the adhesive.
Apply the Glue:
Spread the glue over the edges of the crack. Squeeze the tube gently to release a small amount of glue at a time, avoiding excess. Plastic glues dry quickly, so be prepared to work fast. Use a cloth or wipe to dab any excess glue and prevent hardening.
Join the Pieces:
Line up the edges of the broken pieces carefully. Once the glue is applied and the pieces are aligned, press them together firmly. Apply constant pressure for at least 30 seconds to ensure a secure hold.
Additional Tips:
If the crack is larger, you may need to use a different method, such as welding with a soldering iron or filling the crack with a plastic slurry created by melting plastic in acetone. For simple glue repairs, ensure proper ventilation or wear a facemask to avoid inhaling strong glue fumes.
With these steps, you can effectively use glue to mend your broken plastic bucket, restoring it to functionality.

Welding plastic strips to mend a broken plastic bucket
Welding plastic strips is an effective method for mending a broken plastic bucket. This process involves using plastic welding rods or strips to fill and seal the cracks or holes in the bucket. It is important to first identify the specific type of plastic the bucket is made of, as different plastics have different welding requirements. Polyethylene, for example, is a common plastic used in buckets and is known for its stability and resistance to reactions with other substances. Due to this stability, achieving quality repairs with adhesives is challenging, making welding the preferred repair method.
To begin the welding process, ensure that the bucket is clean and dry. Cut the welding rod or strip to a suitable length, slightly longer than the crack or hole being repaired. If necessary, use a soldering iron to remove any excess plastic or to smooth out the area around the crack. Hold the welding rod approximately 1/2 inch above the damaged area and use a plastic welder to melt the plastic into the hole, filling it completely. Turn off the welder and allow the plastic to solidify.
Once the plastic has cooled and hardened, use a file or sandpaper to smooth out the repaired area, ensuring it is flush with the surrounding surface. For larger holes, it may be necessary to use a cardboard backing to prevent run-off and provide support during the welding process. This can be attached to the back of the hole with tape or a hand clamp.
When selecting welding strips or rods, choose a colour that matches the bucket for a more invisible repair. It is also crucial to use a welding rod with the same or lower density as the bucket. This ensures compatibility and a strong weld. Poly Welder Pro Polyethylene Welding Strips, available in various colours, are specifically designed for welding polyethylene and can be purchased online.

Using a soldering iron to mend a broken plastic bucket
Mending a broken plastic bucket with a soldering iron is a simple and effective method. Most common plastics are thermoplastic, which means they can be heated and remoulded. Before you begin, ensure your work area is well-ventilated as melting plastic produces harmful fumes. It is also recommended to wear a breathing mask.
First, clean and dry your bucket. Repairs will be stronger and last longer when you start with this simple step. Next, plug in your soldering iron and set it to the lowest setting, usually no higher than 400 °F (204 °C). While the iron is heating up, prepare the rest of your materials. Ensure the tip of the soldering iron is clean and do not rest it on anything flammable.
Once the soldering iron is heated, push the edges of the crack together so they connect but do not overlap. Try not to stretch or bend the rest of the plastic. If the edges of the crack cannot connect, you can use a small piece of scrap plastic as a patch. Cut the plastic to a size that fits the crack and try to use the same type and colour of plastic. Melt the edges of the patch and the crack with the soldering iron, then fuse them together.
Lightly rake the hot tip of the soldering iron over the edges of the crack until they melt and fuse together. Ensure you heat the plastic evenly so it fuses together smoothly. Allow the plastic to fully cool and set before using the bucket.

Using acetone to mend a broken plastic bucket
Prepare the Materials and Work Area:
Firstly, ensure you are working in a well-ventilated area or wear a facemask to avoid inhaling the acetone fumes. Fill a glass or metal container with acetone, being careful not to use a plastic container as acetone will melt it. You will also need some scrap plastic; ideally, use a type of plastic that matches the cracked plastic bucket.
Create the Acetone Slurry:
Take the scrap plastic and slowly add it to the acetone. You can use a drill with a drill bit to create plastic shavings, which will increase the surface area and speed up the process. Slowly mix the acetone and plastic until you form a goopy slurry or putty. This mixture can be adjusted to suit your needs; a thicker consistency will make it easier to handle and apply.
Apply the Acetone Slurry:
Before applying the slurry, clean the area around the crack in the bucket. Carefully brush or spread the acetone slurry onto the crack, ensuring you fill it completely and evenly. You can also apply the liquified plastic to the underside of the crack to make it less visible. The acetone will eat into the existing plastic, creating a strong bond.
Allow the Acetone to Evaporate:
Once you have applied the acetone slurry, let it dry. The acetone will evaporate, leaving behind a solid piece of plastic that has filled and bonded the crack. You can then choose to sand or paint over the repaired area for a smoother finish.

Using plywood to mend a broken plastic bucket
To fix a broken plastic bucket using plywood, follow these steps:
First, find a piece of plywood that is as wide as the bucket at its widest point. The plywood should be at least 1/2" thick, but 3/4" thick plywood will also work. If you don't have any plywood available, you can purchase some from a home store.
Next, measure the diameter of the bucket and mark this out on the plywood. Find the middle of this length and mark it. You can use a scrap metal bracket, a nail, and a pencil to draw out the circumference by pushing the nail through a hole in the bracket and swinging the pencil against the bracket's edge.
Use a band saw, jig saw, or hand saw to cut out the circular shape you've drawn. Trim the bottom edge of the wooden circle at a 45-degree angle to allow it to fit snugly inside the bucket. Sand both sides of the wooden disc and the edges to ensure smoothness and remove any sharp bits.
Flip the bucket over onto a smaller diameter object, such as a trash can, to use as a brace and prevent the wooden disc from falling out. Find screws that are shorter than the thickness of the plywood to avoid them poking through into the inside of the bucket. Use a drill bit that is smaller in diameter than the screws so that the threads have something to grab onto. Drill holes around all the cracked parts of the bottom and screw everything down until it looks flat and secure. Use longer screws for the sides, drilling holes around the bucket into the sides of the plywood disc, spaced about 3 inches apart.
Finally, apply glue to the wooden disc. E6000 glue is a good option as it is flexible and will move with the bucket without breaking. Press the disc into the bucket, and you can even stand on it for extra pressure.
Now your bucket is ready to be filled and used again!
