Getting the lid off a sealed 5 gallon paint bucket can be a frustrating task if you don’t know the proper techniques. The lid fits tightly and once the paint dries and seals it, the suction can make it nearly impossible to remove the lid without the right tools and methods. Don’t force the lid and end up spilling paint everywhere or ruining the lid so it can’t be properly resealed. Follow these steps using common household items to get the paint bucket lid off efficiently.

Try a paint bucket opener tool
A specialty paint bucket opener tool is designed specifically for removing tight lids from paint cans and buckets. The simple handheld tool has two flat metal prongs that you wedge under the lid and then twist the pliers-like handle to pry up the lid up and break the seal. This takes advantage of leverage for a quick and easy way to pop the top off. The tool can be purchased at any hardware store or home improvement center, usually for around $5-10. Keep one on hand if you frequently need to open paint cans.
Use a hammer and wood block
If you don’t have a paint bucket opener tool, you can make one yourself using common household items. Take a block of wood, like a 4 inch wide segment cut from a wood dowel or 2×4. Place the wood block flat on top of the paint bucket lid, near the edge. Take a hammer and give the wood block 1-2 firm hits. The focused force should break the lid free from the sealed edge. Be careful not to dent or damage the lid. You can also try gently tapping around the lid edge to break the seal.
Wedge a paint stirring stick under the lid
Another common household item that works is a paint stirring stick. Metal ones are best, but wood ones can work too. Wedge the thin edge of the stick into the tiny gap between the paint bucket lip and lid. Slowly work your way around, gently prying up the edge of the lid as you go. Once you’ve pried up the lid all the way around, it should pop free. Be careful not to bend or snap the stick. This may take a few minutes but can save you if you have no other tools.
Use a screwdriver
For a similar approach, a large, flat-head screwdriver can be carefully wedged into the gap at different points under the lid. The solid metal shaft and leverage of the screwdriver allows you to pry the lid up gradually. Tap the screwdriver gently with a hammer if needed to wedge it further under the lid. Go slowly and be careful not to puncture or scratch the paint bucket with the screwdriver tip.
Cut or peel the seal
Some paint bucket lids have a thin foil seal around the underside rim to create an airtight seal. If you cut through or peel away this foil liner, it breaks the vacuum lock allowing the lid to pop off easily. Use a utility knife to carefully slice through the foil at one spot on the lid rim. You can also try peeling it away with your fingers or pliers. With the seal broken, the lid should lift off without much effort.
Hit the side of the bucket
If you don’t want to pry anything under the lid, simply smacking the side of the paint bucket with a hammer, mallet, or piece of wood can sometimes shock the lid loose. Give the bucket several firm whacks around the outer sides and base, avoiding hitting near the handles. The vibration can help dislodge the lid. However, this is less controlled and risks spilling paint if done too forcefully.
Use hot/cold water
Heating or cooling the sealed lid and paint bucket can also help release the stubborn lid. Very hot water from the tap or a kettle poured over the lid may soften the dried paint enough to penetrate the seal. Allow it to soak in briefly. Chilling the bucket with cold tap water, ice, or in the freezer for 30 mins before opening can also help contract the metal lid away from the bucket rim seal.
Puncture the lid
If all other methods fail, an awl, nail, or drill can be used to puncture the center of the paint bucket lid. This breaks the seal for air to enter allowing the lid to be removed. However, this permanently damages the lid so it can’t be properly resealed. Only puncture as a last resort if you don’t intend to use the remaining paint. The hole will prevent you from storing the paint for later use.
Avoid forcing with knives or chisels
Never pry at paint bucket lids with knives, chisels, screwdrivers, or other sharp tools. You are likely to irreparably damage the lid, scratch the paint bucket, bend your tool, or have it slip and injure you. Any tool you wedge under the lid should have dull, flat edges to prevent puncturing the metal or plastic.
Use lubricant
Spraying lubricant like WD-40 on the seam between the paint bucket and lid can help it release. Allow the lubricant to soak in for 5-10 minutes. The oil will seep into the seal and weaken the suction grip. Go slowly and be careful not to get lubricant on the work surface or your hands to avoid slipping.
Tap lid with rubber mallet
For a more controlled impact, use a rubber mallet to lightly tap around the bucket lid rim. This focuses the force on the lip rather than the sides, weakening the seal. The soft rubber also reduces denting. Continue lightly tapping until the seal breaks free. Remember to open away from you in case paint splashes out.
Wear gloves and eye protection
Be sure to wear thick work gloves and eye protection before attempting to open the paint bucket. Gloves protect your hands from sharp metal lid edges. Safety glasses or goggles prevent paint splatter or tools slipping into your eyes. A paint bucket under pressure can spray paint when opened, so precautions are a must.
Use towel or rag for grip
To help grip the paint bucket when trying to twist the lid off, wrap a towel or cleaning rag around it first. The extra friction helps you get a solid grip, even with paint on the bucket exterior. Place the rag over your gloved hand and squeeze tight as you turn the lid. This allows you to really bear down and apply more force.
Twist and rock the lid
Once you’ve broken the lid free from the seal, you still need to twist and lift it off. Gripping tightly with a rag, use an up-down rocking motion as you twist back and forth to break the stubborn lid loose. The motion provides extra leverage to release the suction. Be patient and keep trying different spots until the lid pops free.
Vent and reseal properly
When resealing a paint can, make sure to vent it properly by placing a nail or skewer through the rim seal break before clamping the lid down. This allows air exchange to prevent suction lock. Once sealed with the vent hole, store upside down to prevent leaking and keep the paint fresh. Tape over the hole when ready to use again. Then open, remove tape, and reseal as before for storage.
Conclusion
Removing stuck paint bucket lids takes a few tricks, but goes quickly once you get the hang of it. The key is breaking the airtight seal using common tools for leverage and controlled force. Avoid puncturing the lid to keep the paint usable. Remember safety gear, vent for resealing, and the lid will pop off easily next time paint day comes around.
