How Do You Store Paint Supplies?
Sep 3, 2026 / Public Storage
Store paint supplies at home by cleaning brushes and rollers, sealing paint cans tightly, labeling every container, and keeping materials in a cool, dry area away from direct sunlight and extreme temperatures. Store paint, solvents, mineral spirits, paint thinner, aerosols, and related products outside a storage unit.
A storage unit can hold dry household items while you revamp a room, but it cannot hold paint or other hazardous materials. Keep painting supplies in an appropriate at-home area and follow product labels and local disposal guidance.
Paint Supply Storage Essentials:
- Store paint, paint thinner, mineral spirits, solvents, aerosols, and other hazardous materials at home, not in a storage unit.
- Clean brushes and rollers according to the paint and tool manufacturer instructions.
- Let brushes, rollers, trays, and drop cloths dry fully before putting them away.
- Wipe paint-can rims before closing lids.
- Label paint cans with the color, room, finish, and date.
- Keep paint cans upright in a cool, dry at-home storage area.
- Store paint cans on a stable, low shelf away from direct sunlight and temperature extremes.
- Review local disposal guidance for paint that is dried out, separated, hardened, or no longer usable.
Paint Supply Storage at a Glance:
How Should You Clean Paint Brushes and Rollers?
Clean paint brushes and rollers according to the paint and tool manufacturer instructions. Water-based paint tools may use water for cleaning, while oil-based paint tools may require a product-specific cleaning method.
Let brushes and rollers dry fully before putting them away. Reshape brush bristles after cleaning and store brushes so the bristles do not bend or flatten.
Do not place wet brushes, rollers, paint trays, or drop cloths in a storage unit.
How Do You Store Leftover Paint?
Store leftover paint in its original can when the container is in good condition and the lid closes properly. Wipe the can rim clean, place the lid on evenly, and close it according to the manufacturer’s instructions.
Label every can with:
- Paint color
- Brand
- Finish
- Room or project
- Date opened or used
Store paint upright in an appropriate at-home location that stays cool and dry. Keep paint away from direct sunlight, heat sources, freezing temperatures, children, and pets.
Can You Store Paint in a Storage Unit?
No. Do not store paint, paint thinner, mineral spirits, solvents, aerosols, or other hazardous materials in a storage unit. These products are prohibited because they can create fire, leak, and air-quality risks.
Use storage only for dry, approved household items, such as furniture, boxes, dry tools, clean drop cloths, and other permitted belongings.
How Should You Store Paint Brushes and Rollers?
Store paint brushes and rollers only after they are cleaned and fully dry. Keep brushes in a container that protects the bristles, and store rollers where the covers will not become crushed or misshapen.
Use this process:
- Clean brushes and rollers according to product instructions.
- Let tools dry fully.
- Reshape brush bristles if needed.
- Store brushes in a labeled container or brush holder.
- Keep roller covers in a dry bin or box.
- Group trays, stir sticks, painter’s tape, and dry project tools in a separate labeled bin.
Use labels such as:
- Painting Tools — Brushes and Rollers
- Interior Painting Supplies
- Dry Drop Cloths and Trays
- Furniture Revamp Tools
- Painter’s Tape and Sandpaper
How Should You Store Dry Painting Tools in a Storage Unit?
Store only dry, approved painting tools in a storage unit. This can include cleaned brushes, dry rollers, empty trays, dry drop cloths, painter’s tape, sandpaper, and dry hand tools.
Pack dry tools in labeled bins and group them by project or room. Keep all paint cans, liquids, solvents, aerosols, and chemical products at home.
How Should You Store Dry Drop Cloths and Tarps?
Store drop cloths and tarps only after they are clean and fully dry. Fold lightweight canvas drop cloths into manageable squares, and roll larger tarps loosely to reduce sharp folds.
Place dry drop cloths in labeled bins or fabric bags. Do not store wet or paint-covered materials in a storage unit.
How Do You Dispose of Old Paint?
Dispose of old paint according to local household hazardous-waste guidance. Do not pour paint, paint thinner, or solvents into sinks, storm drains, or regular trash unless local rules specifically allow the disposal method.
Contact your local waste agency or household hazardous-waste program to confirm accepted materials, drop-off dates, and preparation requirements.
Keep Your Painting Supplies Ready for the Next Project.
Paint supplies stay easier to manage when brushes and rollers are cleaned, dry tools are labeled, and leftover paint stays in an appropriate at-home storage area. Keep paint and hazardous materials out of storage units, then use storage for dry project materials that do not fit your garage, closet, or workspace.
Find a Public Storage location near you to reserve space for dry drop cloths, clean painting tools, furniture, and household items while you organize a home project.
A clear project-supply system makes the next room refresh easier to begin.
