How to Store Paint
When it comes to storing paint, a little preparation can make a big difference. At RGB House Painters, we always seal paint cans tightly using a rubber mallet to avoid denting the lid. Denting the lid can lead to leaks or air exposure.
Before sealing, it’s important to carefully clean the rim of the can. It will help to create an airtight seal, which helps to preserve the paint and also makes it easy to open it later when needed.
We also emphasize the importance of choosing the right storage location. Paint should be kept in a cool, dry place—away from direct sunlight, extreme temperatures, or damp areas like basements without proper ventilation. Moisture, heat, and cold can lead to spoilage, causing clumps or separation that’s hard to reverse.
Leftover paint is an investment, and preserving its quality matters! Just make sure everything is sealed properly and stored in a cool, dry space, away from moisture and temperature swings.
Proper Paint Storage Conditions
For the best results, we always store paint between 15–27°C, avoiding freezing or overheating to prevent spoilage. Temperature swings can ruin paint quality, so we make it a point to store leftover paint in climate-controlled areas to protect it.
While basements can work, we’re careful to choose spots that are moisture-free and well-ventilated to prevent mold or rust from developing. Keeping the environment consistent is key to preserving paint shelf life.
Also, never leave a can sitting directly on concrete floors, as this can cause rusting. Instead, you can put the paint cans on a shelf. When storing the paint, always check lids to ensure they are tightly sealed. These small steps keep paint fresh and ready to use for future projects.
Proper paint storage is all about planning ahead. Always label cans clearly with details like the color, room used, and date of purchase. This makes it easy to identify the right paint for touch-ups in the future.

How to Dispose of Paint
When it comes time to dispose of paint, it’s important to follow local regulations for proper disposal. Many communities have specific guidelines for disposing of paint, such as taking it to a hazardous waste facility or mixing it with cat litter to solidify before throwing it away. Below are simple steps to make this process easier for you.
How to Dispose of Water-Based Paint
Water-based paints, like latex, are easier to dispose of than oil-based options. But they still need proper handling to minimize waste and protect the environment. One of the easiest methods we use is drying out the paint completely before disposal.
We suggest leaving the lid off in a well-ventilated area for the paint to dry. If you have a cat, you can mix the paint with cat litter for a quick dry. You can also mix the paint with shredded paper or any other absorbent. Once the paint is solidified, you can safely dispose of the paint following local disposal guidelines.
If you have larger amounts of leftover paint, we always recommend recycling options. Many local recycling programs accept dried paint or empty paint cans for eco-friendly disposal. These programs make it easier to keep paint cans out of landfills. They also give the paint materials a second life.
We also encourage our clients to check for community drop-off points or municipal recycling centers to handle their own disposals in an environmentally responsible way.
Recycling paint cans is another simple step we often recommend to keep waste minimal. At RGB House Painters, sustainability matters—not just in the products we use but also in how we manage leftover materials.
How to Dispose of Oil-Based Paint
Oil-based paints and stains require extra care because they’re flammable and considered hazardous waste. At RGB House Painters, we understand the importance of proper handling to protect the environment and follow local regulations.
One thing we want to make very clear is to never pour oil-based paint down drains or throw it in the trash. This can lead to contamination and safety risks, as well as damage to your property.
It’s best to keep oil-based paints tightly sealed in their original containers. You can store them in cool, dry areas, away from heat sources or open flames. Flammable paint handling is all about minimizing risk. This starts with secure storage and proper labeling so we always know what we’re dealing with.
Please remember to bring these items to designated hazardous trash collection sites when the time comes to dispose of them. These facilities are fully prepared to safely dispose of solvent-based paint. It is highly recommended that homeowners always refer to their municipality’s regulations regarding the locations and schedules of drop-offs. Responsible disposal not only protects our community, but it also decreases negative environmental repercussions.
Recycling and Donating Leftover Paint
Giving leftover paint a second chance is one of the easiest ways to reduce waste and support the community. We often recommend donating unused paint to schools, charities, and community centers.
Many organizations appreciate receiving high-quality paint for renovations or art projects. It’s a simple way to help others while keeping perfectly good materials out of landfills. Recycling leftover paint is an eco-friendly option we encourage.
Local recycling centers make it easy to drop off unused or dried paint. These facilities ensure leftover paint is processed safely, whether it’s repurposed for new products or disposed of in an environmentally responsible way.
At RGB House Painters, we believe every drop of paint has potential. Recycling and donating to a local group have big environmental benefits. Reusing paint in a sustainable way that benefits your community.
