What type nap roller to use for satin finish interior paint for a bathroom?

For applying satin finish interior paint in a bathroom, a ⅜ to ½-inch nap roller is ideal. This nap length provides a good balance, allowing for smooth application while still holding enough paint to cover the surface effectively. Opt for a roller made of synthetic materials, such as microfiber or polyester, which work well with water-based paints and help achieve a smooth finish. Additionally, ensure the roller is of good quality to minimize lint and roller marks.
