Short answer
Use foam for small, flat, smooth parts in semi-gloss or gloss: cabinet doors, flat doors, shelves, furniture. Use microfiber (or another woven cover) for walls and ceilings, for anything with even slight texture, and whenever you need to cover area quickly. If you are only buying one, buy microfiber.
Side by side
| Foam | Microfiber | |
|---|---|---|
| Best surfaces | Smooth, flat, small: cabinet doors, flat doors, furniture, shelves | Smooth to lightly textured walls and ceilings, doors, trim |
| Paint held | Low; frequent reloading | High; Benjamin Moore describes microfiber blends as high capacity |
| Texture | Cannot reach into texture | Short naps handle light texture; longer naps exist |
| Finish | Very flat, minimal stipple when rolled slowly | Smooth with a fine, even texture |
| Lint | No fibers to shed | Low once de-linted |
| Common problem | Bubbles if rolled fast; edges can leave track lines | Spatter and drips if overloaded |
| Reuse | Often treated as disposable | Washable and reusable |
When foam wins
Foam shines on enamel over smooth, flat parts where any stipple would show: a slab cabinet door, a flat interior door, a bookshelf. Shur-Line sells Cabinets and Doors foam covers in 4 and 6 inch sizes, and Wooster sells a 9 inch Pro Tiz foam cover, both pitched for smooth results with minimal stipple (retailer listings). Bob Vila’s testers found a foam mini roller left a smooth finish on smooth surfaces but performed poorly on anything textured.
- Load it fully, then roll off the excess on the tray so it does not drip.
- Roll slowly and lightly; speed makes bubbles.
- Finish each panel with one light pass in one direction, end to end.
When microfiber wins
Anything bigger than a door, and anything with texture. Benjamin Moore says microfiber blends are designed for high capacity and smooth, consistent paint release; it also claims microfiber can hold up to three times more paint than a standard cover (the maker’s figure). On walls, more paint per load means fewer reloads and an easier wet edge, which is what prevents roller marks.
Purdy groups microfiber with the woven fabrics that leave little lint and a very smooth finish, and pairs woven covers with glossy sheens and enamels (Purdy).
And the third option: short woven
For cabinets in particular, many painters skip both and use a 1/4 inch or shorter woven cover on a 4 to 6 inch frame. It holds more paint than foam and leaves less texture than a longer microfiber. See the best roller for cabinets.
Questions people ask
Do foam rollers leave a smoother finish than microfiber?
On small, smooth, flat parts, foam can leave a very flat finish with little stipple; Shur-Line and Wooster both sell foam covers on that promise. On walls, a short-nap microfiber or woven cover is usually the better tool because it holds more paint and keeps a wet edge longer.
Why does my foam roller leave bubbles?
Rolling too fast or pressing too hard pumps air into the paint. Load the foam evenly, roll slowly with light pressure, and finish with one light pass in one direction. Paint that is thick or partly dried also bubbles more.
Can I use a foam roller with oil-based paint?
Many foam covers are sold for both water and oil-based enamels, varnishes and urethanes, but solvents can attack some foams. Check the sleeve; if it does not list oil-based products, do not use it with them.
Does microfiber shed?
Any fresh fabric cover can release some fibers. Benjamin Moore suggests de-linting with painter’s tape wrapped sticky side out around your hand, and notes that cheaper covers tend to shed more.
