Paint rollers can be stored for short periods of time without being cleaned, but they will need to be wrapped to prevent the paint from drying out. Wrapping the roller in plastic wrap, cling film, or aluminium foil will prevent air from getting to the roller, keeping the paint from drying. For longer storage, the roller should be cleaned with soap and water and allowed to dry completely before being wrapped and stored. Some people also suggest moistening the roller before painting to improve the finish and reduce paint usage.

Wrapping the roller in plastic wrap or aluminium foil
Wrapping a paint roller in plastic wrap or aluminium foil is a great way to prevent paint from drying on the roller. This method works by preventing air from getting to the roller, thereby stopping the paint from drying. This method is ideal for short-term storage, such as between coats of paint, and can keep the roller usable for up to 2 weeks.
To use this method, leave the paint on the roller and wrap it tightly in plastic wrap or aluminium foil without cleaning it first. This technique works best for solvent-based paints, as these dry through evaporation, so depriving them of air keeps them from hardening.
It is important to note that this method does not work as well with foil, as it allows some air to get into the covering. Plastic wrap is a better option for this reason. Additionally, this method should not be used for long-term storage, as the paint will eventually dry and crust at the edges. For longer storage, it is recommended to clean the roller with soap and warm water, or with mineral spirits if it was used with oil-based paint.
Another method for storing a paint roller for later use involves using a damp towel. First, wet a shop towel or paper towel, then wring it out so that it is damp but not dripping. Next, place the roller on the edge of the towel and roll it up, so that the towel is wrapped around the roller. Finally, roll the towel-wrapped roller in plastic or place it in a Ziploc-type bag. The damp towel helps to keep the roller from drying out for longer than if it were wrapped in plastic alone.

Placing the roller in an airtight bag
If you're looking to store a paint roller for a short period of time, such as 2 hours, you can simply wrap the roller without cleaning it first. The whole point of wrapping it is to leave the paint on the roller and prevent air from reaching it, thereby stopping the paint from drying. You can use cling wrap, aluminium foil, or plastic wrap for this purpose.
However, if you're aiming for longer storage, tools should be cleaned. One effective method for storing a paint roller for an extended period is to use a damp towel and plastic. First, take a shop towel or paper towel, dampen it, and then spread it out flat. Place the roller on the edge of the towel and roll it up so that the towel envelops the roller. Finally, roll the entire setup in plastic or place it in an airtight bag, such as a Ziploc bag. The damp towel helps prolong the storage time compared to using plastic alone.
Alternatively, you can skip the towel and simply place the roller directly into an airtight bag. Make sure to remove as much paint as possible from the roller before storing it in the bag. This method can effectively preserve the roller for several weeks.
It's important to note that failing to properly store a paint roller can lead to crusty, dried paint, rendering the roller unusable. Additionally, different types of paint, such as oil-based or water-based, may require specific cleaning methods and solvents for effective long-term storage.

Using a wet towel and plastic bag
Keeping paint rollers wet between coats can be a tricky business. One method that can be used is to wrap the roller in a wet towel and plastic bag. This method can keep rollers usable for many days.
First, take a shop towel or paper towel and get it wet. Ring it out so that it is damp but not dripping. Spread the towel out flat, then place the roller on the edge of the towel and roll it up so that the towel surrounds the roller.
Next, roll the towel-covered roller in plastic or place it in a Ziploc-type bag. It is important to squeeze out as much air as possible. The damp towel will help to keep the roller from drying out, and the plastic bag will provide an additional barrier to the air.
This method is more effective than using plastic bags alone, as it is difficult to seal a plastic bag well around a roller. Thin plastic bags can also be slightly porous, allowing solvents or moisture to escape and the paint to harden.
For longer storage, it is recommended to clean the roller thoroughly. One source suggests that washing the roller with soap and warm water will allow it to be stored for 2 hours, 2 days, 2 weeks, or even 2 years!
Another option for keeping rollers usable for longer periods is to place them in the refrigerator. This can increase their useful life by weeks, or even months. However, freezing rollers is not recommended for latex paints, as it can cause the paint to become stringy and semi-solid.

Rinsing and spinning the roller before use
To begin, simply rinse the roller cover with water. For latex paint, use water, and for other paint types, use the appropriate thinner. Ensure you remove any excess water from the centre tube, as you don't want dripping.
Next, take the damp roller to a clean, flat surface. This could be an unused section of the wall you're painting, a smooth piece of plywood, or even a paper grocery bag. Avoid newspaper, as the ink may transfer to the roller. "Paint" the water onto the surface using quick, zigzag strokes, zipping the roller around to get out the remaining water and ruffle the nap.
After this step, your roller should be slightly damp, ready to absorb and release paint evenly. If you've removed too much water, you can always re-wet the roller and repeat the process.
Additionally, if you're using a new roller, you can preemptively remove lint by rolling the cover over some painter's tape before rinsing and spinning. This simple step will help ensure your walls remain fuzz-free.

Storing the roller correctly
Storing your paint roller correctly is crucial for maintaining its quality. Here are some detailed tips for storing your paint roller:
Cleaning the roller
Start by scraping any excess paint off the roller back into your paint tray with a putty knife. Then, roll the remaining paint onto a piece of scrap paper. Clean your roller immediately after use for the best outcome. For acrylic paints, rinse the roller in a bucket of water, squeeze out as much paint as possible, and then use a roller cleaner. For oil-based paints, you'll need turpentine (turps). Place the roller in a container with turpentine and shake it, then wash the roller in warm soapy water, shake out the excess water, and place it on its end to dry.
Wrapping the roller
Once the roller is clean and dry, you can wrap it in plastic wrap or aluminium foil. Foil is preferable as it is virtually airtight, conforms to the shape of the roller perfectly, and leaves minimal air for drying. If you use plastic wrap, you can seal the roller in an airtight bag, squeezing out all the air.
Storing the roller
Store the wrapped roller vertically or horizontally in a cool, dry place away from direct sunlight. If you need to store the roller for less than a day, you can skip the cleaning process and simply wrap the roller in plastic wrap or place it in a bag and put it in the refrigerator.
Maintaining the roller
Over time, roller covers may develop fuzzy edges that can affect paint application. To address this, use sharp scissors to trim away any dried paint flakes or fuzzy fibres from the ends of the cover. Properly storing your roller during any phase of the project will ensure it's ready and in good shape when you need it. With proper care and maintenance, your paint roller can last for about six months.

Frequently asked questions
You can wrap the roller in plastic wrap, aluminium foil, or cling film to prevent air from getting to the paint and drying it out. If you're waiting overnight or longer than 24 hours, you can place the roller in an airtight bag after wrapping it, squeezing out all the air, and then store it in the fridge or a cool, shaded place.
You can line the roller tray with cling film or a liner to prevent paint from drying on it.
Yes, you can wet your paint roller before use if you're using latex paint. Wet the roller until it is fully wet, then get any remaining water out of the centre tube. Take the dripping roller over to a clean, flat surface and "paint" the water onto the surface in quick strokes to get out the excess water.
