Choosing the right paint roller significantly impacts both the smoothness of the work and the appearance of the finished paint surface. A smooth door, a standard interior wall, and a rough plastered surface all require different rollers.
The most important factors in choosing a roller are the smoothness or roughness of the surface to be painted, the paint to be used, the desired surface texture, and the size of the area to be painted.
A good basic rule is simple: the smoother the surface and the finer the desired finish, the shorter the roller nap should be. For rough and uneven surfaces, on the other hand, a longer nap roller is chosen, as it reaches better into the depressions of the surface.
Short-nap rollers for smooth surfaces
A short-nap roller is suitable for smooth or nearly smooth surfaces where the goal is as even and fine a paint surface as possible. The short nap leaves very little surface texture caused by the roller, which makes it a good choice for projects requiring a fine finish.
Typical applications include:
- doors and furniture
- moldings and panels
- smooth wood and sheet surfaces
- metal and floor surfaces
- very smooth wall surfaces
- surfaces to be varnished and painted as a final finish
Short-nap options in C.E. Lindgren's selection include Anza Pro Super Huopa, CEL felt roller, and CEL foam roller.
Felt rollers are particularly suitable for surfaces where a neat and even finish is desired. A foam roller, on the other hand, leaves a very fine surface, but it is not automatically suitable for all paint types. Suitability should always be checked from the paint manufacturer's instructions.
A short-nap roller typically picks up less paint than a longer-nap roller. In return, it allows for controlled application and a fine finish.
Medium-nap rollers for walls and ceilings
A medium-nap roller is a versatile general choice for painting interior walls and ceilings. It combines good paint absorption, even paint release, and a clean surface finish.
Medium nap is especially suitable for:
- plasterboard walls
- skimmed wall surfaces
- interior ceilings
- lightly textured wallpapers
- fine-textured plastered surfaces
- smooth and semi-rough interior surfaces
- general renovation and maintenance painting
This group includes Anza Pro Super Titex, Anza Pro Super Micmex, CEL Microstar and CEL Keltaraita.
Anza Pro Super Titex is a versatile option for general wall and ceiling painting. Anza Pro Super Micmex and CEL Microstar are microfiber rollers, whose strengths are good paint absorption and even paint release. CEL Keltaraita, on the other hand, is a practical general-purpose roller for standard interior painting projects.
A medium-nap roller is often a safe choice when the surface to be painted is relatively even but not completely smooth.
Long-nap rollers for rough surfaces
The coarser and more uneven the surface to be painted, the longer the roller nap generally needs to be. A long nap picks up plenty of paint and can effectively carry it even into the depressions of the surface.
Long-nap rollers are suitable for example:
- rough plastered surfaces
- brick and concrete walls
- facades
- textured surfaces
- uneven interior walls
- porous surfaces
- rough wooden surfaces
C.E. Lindgren's selection of long-nap rollers includes Anza Pro Classic Rilon, Anza Pro Super Rimax, Anza Pro Super Wistex, and CEL Vihreäraita.
Rilon is a good and reliable option for painting rough surfaces. Rimax is particularly suitable for projects requiring high paint absorption and effective coverage. Wistex offers controlled paint application on semi-rough and rough surfaces. CEL Vihreäraita is a long-nap general-purpose roller for plaster, concrete, and facade surfaces.
On a rough surface, a roller with too short a nap can leave depressions in the surface unpainted. This slows down painting and can result in an uneven finish. A sufficiently long nap facilitates work and improves coverage.
Rollers for industrial paints and epoxies
Industrial paints, epoxies, and other demanding coatings place different requirements on rollers than ordinary wall paints. The roller material must withstand the chemical properties of the paint or coating used and any solvents.
A standard wall paint roller may not be suitable for two-component paints, epoxies, or strong solvent-based products. The wrong roller material can soften, be damaged, or release fibers into the paint finish.
Suitable options for industrial paints and epoxies include Anza Industrial & Coatings X3, Anza Industrial & Coatings X6, and CEL Nylon.
Anza Industrial & Coatings X3 is suitable for situations where controlled application and a relatively fine surface texture are desired. X6 picks up more coating and is suitable, for example, for slightly rougher surfaces and larger floor coating jobs. CEL Nylon is a durable option for demanding paints, epoxies, and concrete, metal, and industrial surfaces.
When using industrial paints and epoxies, always follow the coating manufacturer's instructions for tools, application, and cleaning.
Roller width is chosen according to the area to be painted
In addition to nap length, attention should be paid to roller width. A wide roller speeds up painting large continuous surfaces, while a smaller roller is better suited for confined and detailed areas.
A roller about 18–25 centimeters wide is a common choice for painting walls and ceilings. For very large open surfaces, even wider rollers can be used.
A mini roller is well suited for example:
- doors and furniture
- moldings and panels
- around windows
- behind radiators
- near corners and edges
- small touch-up painting jobs
The nap length of a mini roller is also chosen according to the surface to be painted. A short-nap roller is used for smooth surfaces and a longer nap for rougher surfaces.
Extension pole makes painting walls and ceilings easier
An extension pole makes painting walls and ceilings faster and more ergonomic. It allows you to work largely from the floor without constant reaching or moving ladders.
With an extension pole:
- working posture improves
- strain on hands and shoulders is reduced
- high surfaces are more easily accessible
- work speeds up
- handling large surfaces becomes easier
A telescopic extension pole is a versatile option because its length can be adjusted according to the object to be painted and the ceiling height.
Prepare a new roller before use
A new paint roller should be prepared before starting to paint. This prevents any loose fibers from ending up in the paint finish.
Remove loose nap with, for example, painter's tape or a roller brush. When using water-based paint, the roller can be lightly moistened with clean water and squeezed almost dry before the first dip into the paint.
For solvent-based paints, industrial paints, and epoxies, follow the paint manufacturer's instructions.
Wash and store the roller correctly
If the roller is to be reused, it should be cleaned as soon as possible after work is completed. Excess paint should first be removed from the roller back into the paint tray.
Water-based paints are usually washed with water and, if necessary, mild soap. For cleaning solvent-based paints, epoxies, and industrial coatings, use the cleaning agent recommended by the paint manufacturer.
The cleaned roller is rinsed thoroughly and left to air dry. The roller should be stored in such a way that the nap does not become compressed or change its shape.

The right roller improves the outcome of the work
The choice of paint roller can be summarized in a few basic principles. For smooth surfaces, choose a short-nap roller; for standard walls and ceilings, a medium-nap roller; and for rough surfaces, a long-nap roller. For industrial paints, epoxies, and other special coatings, use a chemically resistant roller designed for them.
When the roller's nap length, material, and width match the surface to be painted and the paint to be used, the work proceeds more smoothly, and the result is neat, even, and durable.
