Paint rollers are a popular choice for interior and exterior DIY painting jobs due to their ease, versatility, and speed of application. They can be used for multiple coats of paint, but it is important to clean them properly between coats. There are several methods for cleaning rollers, including rinsing them with water and spinning them out or scraping off the excess paint and wrapping them in plastic to prevent drying. Some people also store their rollers in the refrigerator between coats, but this is not necessary if the roller is properly wrapped. For oil-based paints, it is recommended to use a new roller for each coat, as the paint can be difficult to remove from the roller.
Should I change rollers for each coat of paint?

Cleaning paint rollers
While it may seem easier to discard paint rollers after each use, doing so can become costly. Cleaning and reusing high-quality paint roller covers saves money and ensures a better finish.
If you need to take a break during a painting session, wrap the roller first in aluminium foil, a plastic bag, or plastic wrap to prevent air exposure, which dries the paint. You can then store the roller in the refrigerator for up to a week or two. Some painters claim this method is effective for months.
To clean a paint roller, first, remove as much excess paint as possible. Use a putty knife to gently scrape excess paint back into the paint can. Slowly and gently work around the surface of the roller in a downward motion. Finish by using the remaining paint on the roller to touch up bare spots on your wall or roll the excess paint on newspapers until the roller stops releasing paint.
Next, remove the roller from the frame. Wearing gloves, submerge the roller in a bucket of warm water with a few drops of dishwashing liquid. Massage the roller's fibres to remove caked-on paint, making sure to clean every surface.
Rinse the roller with a hose or in another bucket of clean water until all paint is removed. Shake the roller to remove excess water, then allow it to air dry. Place the roller upright on its end or slip it over a pants hanger to dry. Never place the roller on its side to dry, as this will flatten the fibres.
If you used oil-based paint, you must use a solvent like mineral spirits to remove the paint. Always wear rubber gloves and eye protection when cleaning with solvents to prevent skin irritation and splatters to the eyes. Place enough mineral spirits in a bucket to completely cover the paint roller. Work the solvent through the paint with your hands until the bond between the paint and roller is broken. This may take several minutes.
Dispose of the dirty water down a sewer drain connected to a water treatment facility. Never dispose of it down a stormwater drain.

Storing paint rollers in the fridge
When it comes to painting, there are various methods to store paint rollers between coats of paint. Some people choose to discard rollers after each use, while others aim to reuse them. Those who reuse rollers typically clean them after each use, allowing them to dry, and store them for future painting projects.
Now, let's delve into the topic of storing paint rollers in the fridge:
Storing paint rollers in the refrigerator is a common practice recommended by several sources. This method helps prevent the paint from drying on the roller, eliminating the need for cleaning the roller between coats. It is suggested that rollers be placed in plastic bags or wrapped in plastic wrap to create an airtight seal before being stored in the fridge. This technique is particularly useful when there is a gap of several days between coats of paint, as it keeps the roller usable for an extended period.
However, it is crucial to exercise caution when storing paint rollers in the fridge. One should only use water-based paints for this method, as oil-based paints can emit solvents that can ruin the refrigerator and contaminate food. Additionally, some sources advise against placing paint rollers in the freezer, as freezing paint is not recommended.
While storing paint rollers in the fridge can be convenient, it is not the only option. Some people opt to wrap the rollers tightly in plastic wrap or bags without refrigeration, finding that the paint remains wet and usable for the next coat. Others choose to clean their rollers with water after each use, ensuring that the water runs clear before leaving the rollers to dry.
Ultimately, the decision to store paint rollers in the fridge or not depends on personal preference and the type of paint being used. It is essential to consider the potential risks associated with oil-based paints and freezers while also recognizing that proper wrapping and storage can extend the life of paint rollers without the need for refrigeration.

Using plastic wrap to store paint rollers
While it is not necessary to change rollers for each coat of paint, it is important to properly store them to prevent the paint from drying out. One effective method for preserving paint rollers is to wrap them in plastic wrap and store them in a cool place.
Using plastic wrap is a simple and inexpensive way to keep paint rollers fresh between coats. It helps prevent the paint from drying out, allowing for multiple uses before needing to clean the roller. Here is a step-by-step guide to using plastic wrap to store paint rollers:
- Remove the handle from the roller: Although not necessary, removing the handle makes wrapping the roller easier and ensures a tighter seal.
- Wet the roller: Before wrapping the roller, ensure that it is wet. This can be done by dipping the roller in paint or running it under water if you intend to clean it before the next use.
- Cover the roller's entire nap: Make sure to completely cover the roller's surface, ensuring no exposed areas.
- Secure with tape (optional): Plastic wrap usually sticks to itself, but you can use painter's tape for added security.
- Store in a cool place: Once wrapped, store the roller in a cool, dry location. Avoid placing it in direct sunlight or near heat sources, as this can accelerate drying.
By following these steps, you can effectively use plastic wrap to store your paint rollers between coats. It is recommended to restart your project within 24 hours for the best results, although the roller should remain usable for up to a week. Additionally, consider other storage methods such as using plastic bags or refrigeration to further extend the life of your paint rollers.

Reusing paint rollers
Short-term storage:
If you plan on reusing the roller within the next day or two, wrap it tightly in plastic wrap to prevent air exposure and keep the paint from drying. You can also dip the roller in paint to completely coat it before wrapping it up. Another option is to place the roller in a plastic bag and store it in the refrigerator to keep it fresh for a few days. This is especially useful if you are waiting for a coat of paint to dry and need to use the same roller for the next coat.
Long-term storage:
If you won't be using the roller for a while, it's best to clean it thoroughly. Start by scraping off as much excess paint as possible using a roller scraper or your hands. Then, rinse the roller under running water until the water runs clear. You can speed up the process by spinning the roller while rinsing it. Finally, let the roller air-dry before storing it in a plastic bag.
Extending the life of the roller:
A quality roller should last for about 3-5 uses before it starts shedding or dropping lint. To extend the life of the roller, make sure to scrape off excess paint and create an airtight cover after each use. Storing the wrapped roller in a refrigerator can also help keep it fresh for a longer period. However, some people prefer not to use the refrigerator as it may leave the fridge smelling like paint and there may be safety concerns with storing paint near food.
When to discard:
Paint rollers should be discarded when they start to deteriorate and tiny pieces of the nap end up in your paint job. This usually happens after multiple cleanings, as the nap in paint rollers deteriorates with each cleaning. If you are using a cheaper roller, it may be more cost-effective to discard it after each project rather than spending time and resources cleaning it.

Types of paint rollers
There are several types of paint rollers available, each designed for a specific purpose. The type of roller you choose will depend on the size of the area you need to paint, the smoothness of the surface, and the desired appearance.
The most common type of paint roller is the manual paint roller. These typically consist of a handle, a metal frame, and a rotating metal roller. They are usually used for painting interior walls and ceilings, but can also be used outdoors with the right roller cover. However, they may be too long for thin surfaces like baseboards and door frames. Manual rollers are also one of the most affordable options.
Another type of roller is the pad roller, which has a flat pad that absorbs and releases paint onto the target surface in straight, even strokes. This design helps prevent paint splatters, but pad rollers only apply a thin layer of paint, so they are not suitable for covering darker or more vibrant colours.
Textured rollers refer to the roller sleeve rather than the actual roller. They can be used with a manual roller to create innovative patterns or mimic designs like wood grain, brick, or stone textures. The sleeves are made of foam and have individual patterns etched in, but these patterns may be difficult to appreciate on smaller surfaces.
Specialty rollers are similar to textured rollers but are designed by the manufacturer for specific textured paints. They are not just manual rollers with innovative roller sleeves, and while you don't need to use them with textured paint, you may get better results with the specialised tool.
Mini rollers are used to reach tight spots, and you should match the fabric and nap size for a seamless finish.
Other factors to consider when choosing a paint roller include the fabric type and pile height. Woven fabrics, such as microfiber and mohair, provide a smooth finish and prevent lint from being left behind. Knit fabrics like polyester and lambswool hold more paint and cover larger areas faster but leave some stipple.
The nap size, or thickness of the fibres, also varies based on the surface being painted. Low-nap rollers pick up less paint, while high-nap rollers pick up and hold more. For interior surfaces like drywall, cabinets, and metal, use smaller nap sizes (around 1/4 inch). For walls, ceilings, and panelling, a slightly larger nap size of 3/8 inch is suitable. For textured ceilings, stucco, and masonry, a 3/4 inch nap size is recommended, while for outdoor jobs or rough interior surfaces like brick and cinder block, a higher nap size of 1 inch or more is needed for greater paint pickup and faster application.
In addition to the type of roller, it is important to consider the care and maintenance of your paint rollers. If you are not finished painting and need to store your rollers overnight, you can put them in a plastic bag and place them in the refrigerator to prevent the paint from drying. However, do not store them in plastic bags or cling film overnight, as this can change the shape of the roller. After each use, scrape away excess paint and wash the roller in warm water until the water runs clear, then let it air dry.
