Repairing cracked plastic tin seem like a difficult task, simply virtually common plastics are thermoplastic, which means they tin be heated and remolded. The key to fixing cracks in plastic is knowing which method is best to repair the fissure. Smaller cracks can usually exist fixed with glue, hot water, or plastic slurry, while larger cracks may crave some welding with a soldering iron. With the correct method, fixing a fissure in plastic is easier than y'all think.

one
Use plastic mucilage to fix small cracks in plastic. If yous need to reconnect a scissure in plastic, y'all can utilise plastic gum, which is specially formulated to bond plastic surfaces. Plastic gum is often used for making models then it is piece of cake to employ and safe to handle for adults. Brand certain you lot have plenty to connect the whole crack, yous don't desire to take to stop afterwards yous've started applying strong gum!^[1]
- Yous can utilize most super glues also, but check the packaging to make sure it can exist practical to plastic.
two
Use the glue to the edges of the crack. Squeezing the tube gently, spread a layer over the edges you will reconnect. Keep a cloth or wipe nearby in instance you pour also much and dab any excess glue immediately to prevent it from hardening. Glue dries fast to be sure you lot are set to connect the cracked plastic before you lot offset applying!^[ii]
- Stiff glues take strong fumes. Work in a well-ventilated surface area or wearable a facemask when handling the mucilage.
- Wear gloves when using strong mucilage to prevent information technology from getting onto your skin and becoming painful to remove.

Reconnect pocket-sized cracks in plastic using hot h2o. Plastics often do not need extreme heat to go malleable enough to repair a crack. Soaking the plastic in hot h2o tin can make the plastic soft enough to mold and reconnect the edges of the scissure. You can make the plastic set up almost instantaneously by rapidly submerging information technology in cold water.^[5]
2
Fill up a container of hot water and a container of common cold water. Fill up a bowl or container with enough hot water to submerge the cracked piece of plastic. Then fill a container with cold water and keep it nearby so you tin set the plastic after you lot've repaired the cleft.^[vi] Make sure you don't overfill the containers so the water doesn't spill over the sides when you submerge the plastic.
- The water should non be boiling when you lot submerge the plastic.
3
Identify the cracked plastic in the hot water. Yous may not need to fully submerge the entire piece of plastic since you're only repairing a crack and not remolding the whole slice. Dissimilar types of plastic may accept longer to become malleable in the h2o. Leave the cracked plastic in the water for at to the lowest degree 30 seconds.^[7]
- Take the plastic out of the h2o periodically to examination if information technology is soft enough to mold.
- You can use tongs to hold the plastic in the hot water.
- Don't slosh the plastic around in the water. Allow it to sit undisturbed.
4
Have the plastic out of the water and connect the cracked plastic. When the plastic starts to loosen and become malleable enough where you can mold it with your fingers, remove it from the water. Press the croaky edges together to reconnect them. Endeavor not to squish the plastic edges so they don't appear uneven.^[viii]
- Wear gloves or apply tongs to pull the plastic out of the hot water.
5
Submerge the plastic in the cold water to fix. In one case you have reconnected the edges of the scissure, it'due south important that you quickly cool the warm plastic and then that information technology sets into place. Fully submerge the plastic into the container of cool water. Practise not move it effectually in the water and allow information technology to sit for at least xxx seconds.
- You lot can use a C-clamp to hold the crack together when you submerge it in the common cold water, simply be certain non to squish the plastic so it's uneven when it sets.
- Accept the plastic out of the h2o and check to see that it has hardened completely earlier using it.^[ix]
- Submerge as much as the plastic as y'all tin. Cooling the entire slice will help the recently molded plastic gear up improve.

Use acetone to make a plastic putty to fill in cracks. Acetone is a potent solvent that can dissolve plastic down completely. You can apply acetone to make a putty of melted plastic that is peachy for filling in cracks. But you lot shouldn't use information technology for large holes or gaps or it may not prepare evenly.^[ten]
2
Fill up a drinking glass container with acetone. Acetone melts plastic, and then you don't want to fill a plastic container like a cup or bucket with it.^[11] Utilize a drinking glass or ceramic bowl and fill up information technology with enough acetone to completely submerge a few pieces of chip plastic. It may be difficult to fully clean the melted plastic when y'all're finished, so use a basin you don't listen ruining.
- Acetone can emit noxious fumes, so be certain y'all're working in a well-ventilated expanse or wearing a facemask when you use it.
3
Submerge a few pieces of chip plastic in the acetone. You lot'll be melting down plastic to utilize to fill up your crack, so use pieces that y'all don't need. Information technology doesn't affair the shape, because information technology will cook completely earlier you apply it.^[12] If possible, employ scrap plastic that matches the cracked plastic you are repairing.
- Do not become the acetone on your peel as it tin irritate it.
- If y'all tin can't lucifer the same type of plastic, try to match the color as all-time as you tin.
4
Allow the plastic pieces deliquesce in the acetone overnight. The plastic will slowly disintegrate into a thick slurry.^[13] Depending on the pieces of scrap plastic, the time information technology takes to fully intermission down may vary. A safety bet is to allow the plastic to sit in the acetone for over eight hours.
- You lot can speed up the time it takes the scrap plastic to break down by cutting it into smaller pieces.
- If the plastic sludge has any large lumps of plastic in it, information technology may need more time to disintegrate.
five
Pour out the extra acetone. Once the pieces of plastic have fully broken downward in the acetone, they will dissever and sink to the lesser of the container. Advisedly drain the acetone in the sink, leaving only the melted plastic backside. Be careful not to breathe in the fumes.^[14]
- Acetone can eat through plastic and damage your grass so exercise not empty the acetone in the garbage or outside!
- Whatsoever small corporeality of acetone left in the container volition evaporate speedily.
6
Castor the plastic slurry over the crack to fill in the seam. With the acetone fully removed from the mixture, you tin can utilize the plastic slurry made from your scrap plastic. Dip a modest paintbrush or swab into the liquid plastic and use it to fill in the crack. Be sure to make full it in completely and employ the putty every bit evenly as you can.^[fifteen]
- Apply the liquified plastic to the underside of the crack and then it won't be equally visible.
seven

Let the plastic slurry to harden completely. The slurry will speedily begin to bond with the plastic and start to harden. It'southward of import that you let it prepare completely earlier you utilise the plastic or the crevice can reopen. Look at least 1 60 minutes before using the repaired plastic.^[16]

Use a soldering iron to ready larger cracks in plastic. A simple soldering iron is a corking way to set up a crack in plastic. The focused heat from the iron allows you to cook but the edges of the cleft and then you tin reconnect them easily without melting or warping any of the rest of the plastic. They are also easy to utilize and do not crave any extra material.^[17]
- Soldering irons are bachelor at hardware stores and the home improvement section of many stores for about $10.
two
Permit the soldering iron heat upwards. Plug in and turn on your soldering fe and set it to the lowest setting. It may have a little while for the iron to heat upward, but yous can use this time to fix the rest of your materials. You don't want to use the soldering fe until it has reached the set temperature or your plastic may weld unevenly.^[18]
- Practise non rest the soldering iron on anything flammable while it heats up.
- Brand sure the tip of the soldering fe is clean of any balance.
- Plastic melts much easier than metal, so your soldering iron does not demand be higher than 400 °F (204 °C).
3
Connect and hold the crevice together. When the iron is ready, push the edges of the crevice together and so that they connect, but don't overlap each other. Try not to stretch or bend the balance of the plastic. If the edges of the crack cannot connect, you use a small piece of scrap plastic as a patch past melting the edges of the patch and the edges of the crack, and then fusing them together.^[nineteen]
- Use a clamp to agree the crack together and allow you to utilise both of your easily to solder.
- If you lot practise employ a piece of scrap plastic every bit a patch, cutting the plastic to a size that fits the crack, and try to use the same type and color of plastic.
iv
Cook the edges of the cleft with the soldering fe. Lightly rake the hot tip of the soldering over the edges of the crack until they melt and fuse together. Be sure to heat the plastic evenly so it fuses together smoothly. Allow the plastic to fully absurd before using it.^[20] There should non exist a flame or a lot of smoke.
- The soldering atomic number 26 will be very hot, and then take be careful not to burn yourself or anything effectually yous when you're handling it.
- Melting plastic tin can put off fumes that are harmful. Piece of work in a well-ventilated area or wear a breathing mask to avoid breathing in the fumes.
five
Let the plastic to absurd completely. The plastic must cool completely in order for it to set. If you effort to use the plastic before the crack is fully gear up, information technology may reopen and exist harder to repair the next fourth dimension. Remelting plastic can affect its appearance.^[21]
- Look at to the lowest degree 1 hour before using the repaired plastic.
6
Plough off and shop the soldering atomic number 26. When yous are done welding your plastic together, plough off and unplug your soldering iron and permit it to cool. Wipe the soldering tip clean of any plastic residue that may have collected there. Then store the iron in a safe location.
- You lot may demand to scrub the tip of the soldering iron with a brush to remove the remainder.
