Roller cover nap sizes, or thickness of the fibers, varies from low to high based on the surface you are painting. Low-nap rollers pick up less paint, while high-nap rollers pick up and hold more for larger projects.
Surface texture and general environmental factors, including temperature and humidity, should also factor into your roller cover selection. For uniform interior surfaces like drywall, cabinets and metal, use roller covers with smaller nap sizes, like our ¼-inch nap WhiteDove&#;, to ensure a smooth finish. Walls, ceilings and paneling require a slightly larger nap size of 3/8-inch; for lightly textured walls, decks and concrete, use a ½-inch nap; and for textured ceilings, stucco and masonry, use ¾-inch.
For outdoor jobs, or when painting rough interior surfaces such as cinder block, rough wood and brick, look for roller covers with a higher nap, like our 1-inch GoldenEagle&#; for greater paint pickup that reaches every nook and cranny, as well as faster application and increased productivity.

Yes, you can wash out paint rollers and reuse them multiple times, especially if you buy a good quality paint roller that has much more durability than a cheap roller sleeve.
If you are painting just one room in one colour, then you will only need a singular paint roller to finish the job. If you are using multiple colours, we would recommend you get two roller sleeves as this will mean you do not have to fully clean and dry the sleeve before moving on to the other colour. You will not need to get two roller sleeves as these can be very easily cleaned and dried using a paper towel.
There are a number of ways to prevent your paint roller from splattering paint on surfaces that you do not want painting. Firstly, a good quality roller will help minimise paint splatter, which is always a good place to start. Secondly, try not to apply to much pressure to the paint roller. Slow and gentle motions will apply to paint evenly, and if your roller has a good pick-up, it will not require much pressure to apply to paint. Lastly, move the roller in straight motions as when you use a zig zag motion, the paint will gather in corners on the roller and will splatter more often.
The cleaning process will differ depending on if you are using a water-based paint or an oil-based paint. If you have been using a water-based paint, firstly remove the sleeve from the frame and use a scraper or painters tool to scrape out any excess paint back into the paint tin. Once you have done this, you can simply rinse the roller under a tap of warm water until the water runs clear. If you have been using an oil-based paint, you must use a solvent to clean it such as white spirit. Remove the excess paint by scraping it back in the tin and then by rolling as much paint as possible onto a surface you can throw away, such as some paper. This removes as much paint as possible to make the next process as easy as it can be. Fill a tub with white spirit or turps and place the roller sleeve in, making sure it is submerged. Leave the sleeve for 5 minutes and remove it, repeating the process until all paint has been removed. If you keep them container with a lid on it for a few days, the paint will sink to the bottom and the white spirit can be decanted back into the bottle.
Once you have cleaned your paint rollers, store them in a sealed plastic bag until you come to use them again. Avoid getting them dirty as this will mean you will have to clean them again before use.
