3/8 inch nap roller covers work best on semi-smooth surfaces such as drywall and lightly textured walls.
What Handle Fits Which Cover?
Traditional Mini Roller Refills are available in 4 to 6-1/2 inch widths and are designed to mount on a round unthreaded rod approximately 1/4 inch thick rod. Most suppliers use a 7/16 inch round inner roller core with a bearing assembly that slides on and holds. One handle will usually fit both 4 and 6 or 6-1/2 inch widths.. Larger hollow cores also exist from 1/2 inch to 1-1/2 inch diameter. Matching the replacement cover to the handle and Series by Manufacturer is the most desirable.
What’s the difference between knitted, woven and microfiber roller covers?
Knit gives better coverage at a lower cost but some lint (shedding). Woven gives a better finish, less lint but lower paint pick-up and release. Microfiber yields maximum coverage, flawless finish, less lint.
How do I choose the right cover for the job?
For brushes, it’s the type of paint that matters latex or oil. For rollers, it’s the sheen flat to gloss, because the higher the sheen in the paint, the more the surface will show lint as texture from the roller. For semi-gloss or gloss paint, choose a shed-resistant woven cover. To apply flat, eggshell, or satin paint, a high-capacity knitted cover can be used. For a super-fine finish, it’s perfectly okay to use a shed-resistant roller with a flat or satin paint, too.
