How to safely dispose and store your paint products

Storing and disposing of paint properly needs to be a big consideration. 

Industrial paints can have a big environmental impact if they aren’t disposed of appropriately, yet, not everyone knows the best way to stay environmentally friendly. 

Correctly disposing of paints and industrial paint supplies helps to keep waterways clean, divert from landfills, and increase the recovery of resources. 

In this post, we examine how to dispose and store your paint products at all times safely. 

Check your quantities 

Before you buy your paint, check how much of it you will actually need. Estimating the volume required beforehand helps to reduce and minimise any left-over paint at the end. If you do have paint left over, think about future products on the horizon and if this could be used. Could you even use it to upcycle old furniture, or decorate pots, etc.? 

Check with local authorities 

It’s advisable to check with local authorities on their preferences for disposing of paint tins and materials. Usually, paint pots and tins, etc. can go with regular household rubbish and recycle bins, or they can be taken to waste collection sites. However, and again, we would always advise checking first. 

Check where you buy your paint from 

Sometimes the retailer or wholesaler where you have purchased the paint will allow you to return empty paint tins, where they will collect them and dispose of them on a larger scale. It is always worth asking when you’re making your purchase. 

Paint Disposal 

Disposing of leftover paint 

If you have a small amount of paint leftover from a job, where there isn’t quite enough to start a new project, no matter how small, then you can pour the paint onto old newspapers, cloth or cardboard (any absorbent material) and then dispose of these once the paint has dried. 

Disposing of water-based paint 

For all latex, acrylic, or water-based paints, it’s important that you do not pour any remains into drains, down sinks, or directly onto the ground. 

You also shouldn’t put cans of liquid out for rubbish collection, and you most definitely shouldn’t try to burn this type of paint. 

Disposing of paint in this way is extremely harmful to the environment. Contaminating the air, soil, and groundwater. 

Best approach? 

When you have less than a quarter in full of paint, remove the lid and allow the paint to dry out completely (away from children and pets). It will take a few days for the paint to dry, however once dry you can then dispose of it like regular rubbish. 

When you have more than a quarter in full of paint, again, pour the remaining paint onto old newspapers and cardboard, letting the paint fully dry before disposing of it with the rest of your rubbish. 

Disposing of paint spray cans 

Aerosol spray cans must be disposed of safely as these products can ignite and cause serious injury if they puncture and explode. 

If the spray can is empty (you can no longer hear air being released), it can be placed into recycling bins. 

If the spray can is not empty, you will need to spray the contents, in a well-ventilated area, onto cardboard (or other absorbent material) until you can no longer hear the air being released from the can. 

Once the can is depressurised, and the paint has dried on the cardboard, both can be disposed of safely. 

Paint Storage 

Storing leftover paint 

The best way to store leftover paint is by cleaning excess paint from the can and the lid. You should then cover the opening of the can with plastic wrap. This helps to remove the film that often forms when the paint has been sitting for a while. 

Make sure to fit the lid securely and ensure it is completely sealed around the edges. 

Turn the paint container upside down to help seal the paint and keep it fresh. 

All paints need to be stored in a safe place, away from extreme heat – remember paint is flammable.
