Plastic paint tins can be challenging to open, especially when leftover paint dries on the rim and fuses the lid shut. The best way to open a plastic paint tin depends on whether it is new or old. If the paint tin is new, you can use a variety of tools to pry the lid open, such as a quarter, your keys, the back of a fork or knife, or a flat-head screwdriver. If the paint tin is old, you will need to slowly and carefully work your way around the lid as you open it to avoid getting any rust inside the paint. If the lid is stuck, you can try soaking the tin in warm water for 10 minutes to soften the paint, or use WD-40 to loosen the dried paint.

What You'll Learn
Use a flat-head screwdriver to pry open the lid
If you're struggling to open a plastic paint container, it may be because paint has dried and fused the lid shut. To open it, you can use a flat-head screwdriver. This is a common tool that you may already have lying around.
To open the paint tin, start by wedging the end of the screwdriver into the lip of the can. Then, gently push down on the handle of the screwdriver. This will help to push the lid up and release some of the pressure. Remove the screwdriver and repeat this process 3-4 times around the entire lid of the can. After gently lifting in a few different places, the lid should pop right off.
If there is dried paint on the screwdriver, it should be able to wipe off with a paper towel or rag. Be careful not to put too much pressure on the lid when using a screwdriver, or it may become deformed.
To avoid dried paint sealing the lid shut in the future, you can wipe the rim of the can and the inside of the lid with a clean cloth before closing it. You can also cover the rim of the pot and opening with plastic wrap, or apply olive oil or Vaseline with a paper towel or your finger around the edge of the lid.

Soak the can in warm water to soften the paint
So, you've got a paint job to do but your plastic paint tin is stuck shut. One way to loosen the lid is to soak the can in warm water to soften the paint. This is a good method to use if you live in a cold place and your paint has been stored somewhere chilly.
To do this, fill a sink with warm water and float the can in it. You don't need to use extremely hot water—warm to hot tap water will do the job. If you don't want to put the can directly into the water, you can place it in a plastic bag first. This will prevent the can from rusting. Leave the can to soak for 5 to 10 minutes.
While the can is soaking, the warm water will reduce the viscosity of the paint, making it less thick. This means that the paint will flow more easily from the can and will lie more smoothly on the surface you're painting.
After 5 to 10 minutes, remove the can from the water and shake it well. If it still feels cold, return it to the water for a little longer.

Use a paint can opener
Using a paint can opener is a great way to open a plastic paint tin without creating a mess. It is also a very cost-effective tool, often costing less than a dollar. To open a paint can using a paint can opener, push the flat end of the opener into the gap between the can and the lid. Then, gently pry the lid off by placing the paint can opener under the lip of the lid and lifting it up. Rotate the can to move the paint can opener around the entire lid. Be careful not to apply too much pressure when prying, as this can deform the lid and make it difficult to close and open the next time.
If you don't have a paint can opener, you can use a flat-head screwdriver or a putty knife instead. Simply place the head of the screwdriver or the front edge of the putty knife in the gap where the lid meets the can and gently lift up. Continue moving the tool slowly around the edge of the can until the lid is fully loosened and can be removed. If you are using a screwdriver, make sure it has a tip that is about 1⁄4–1⁄2 inch (0.64–1.27 cm) big to avoid putting too much pressure on the rim of the can.
For older paint cans, there may be dried paint around the rim that makes it difficult to open. In this case, you can use a paint scraper to slice along the rim of the lid and loosen any excess paint before trying to pry it open. Additionally, always remember to wear gloves when opening a paint can to avoid getting paint on your hands.

Cover the rim with plastic wrap to prevent dried paint
Covering the rim of a paint tin with plastic wrap is a great way to prevent dried paint from fusing the lid shut. This is especially useful if you are a messy painter and often get paint on the rim of your tin. The plastic wrap acts as a gasket, creating a tighter seal and preventing any paint from drying and sticking the lid in place.
To do this, simply place a piece of plastic wrap over the entire opening of the paint container and then place the lid on top of the plastic, screwing it on as you normally would. The plastic wrap will be between the lid and the container, so the paint cannot stick to the lid. You can also run a small amount of Vaseline or petroleum jelly along the bottom of the grooves of the jar, where the lid screws on, to prevent paint from fusing to the lid.
If you are using a screwdriver to open your paint tin, be careful not to put too much pressure on the lid, or it may get deformed. This will make it harder to close and take off next time. If you are working with an older paint tin, there is a chance that dried paint will get on your screwdriver. This should be able to be wiped off with a paper towel or rag.
If you are struggling to open a plastic paint container, you can try running the lid under hot water for around 30 seconds. The heat will loosen the dry paint, and it should then screw off easily.

Use a knife or key to open
If you're struggling to open a plastic paint tin, you can use a knife or key to pry it open. First, make sure you have placed the paint tin on a flat surface with dust sheets and protectors around. You don't want to get paint on any precious ornaments or surfaces! It's also a good idea to wear old clothes that you don't mind getting dirty.
If the paint tin is new, you can use a key to open it. Choose an old key that you don't use anymore, as you risk bending or breaking it. Insert the flat side of the key under the rim of the lid and gently pry it open, moving the key around the lid as you do so. You can also use a quarter or the back of a fork or knife to open a new paint tin.
If the paint tin is stuck, you can try using a knife to open it. A butter knife or a traditional knife with a flat edge will work, but avoid using anything too sharp as it could damage the tin. You can also use a paint can opener or a flathead screwdriver. Place the flat edge of your chosen tool under the lip of the lid and gently pry the lid away from the can. If you're using a screwdriver, you can also try tapping the edge with a hammer to apply more force. If the paint tin is still stuck, try soaking it in warm water for 10 minutes to soften the paint, or use a cloth dipped in warm water to wipe away any paint around the rim.
To prevent your paint tin from getting stuck in the future, make sure to wipe away any excess paint from the rim of the tin and lid before sealing it closed.
